Why Mitsubishi Mini Splits Are Revolutionizing Home Comfort
Ever walked from a perfectly comfortable living room into a freezing cold bedroom in winter? Or felt like you’re paying to cool empty rooms all summer long? Mitsubishi mini split systems are changing how Pacific Northwest homeowners experience indoor comfort, room by room.
These ductless heating and cooling champions deliver personalized temperature control exactly where you need it. Unlike traditional HVAC systems that treat your entire home as one temperature zone, Mitsubishi mini splits give you the power to create comfort microclimates throughout your house.
Quick Answer: Best Mitsubishi Mini Split Models
- Highest Efficiency: Deluxe FS Series (up to 32.2 SEER2)
- Best for Cold Climates: FH Series with Hyper-Heating (100% capacity at -5°F)
- Most Affordable: Standard GL Series (up to 24.6 SEER2)
- Best for Low Ceilings: MLZ Ceiling Cassette Series
- Best for Attics/Dormers: MFZ Floor-Mounted Series
I’ve seen the delight on homeowners’ faces when they realize their energy bills have dropped by up to 50% after switching to a Mitsubishi mini split system. With efficiency ratings reaching an impressive 32.2 SEER2 – more than double what federal regulations require – these systems sip electricity rather than guzzling it.
What’s equally impressive is how whisper-quiet these systems operate. At just 19 decibels (quieter than a library whisper), you might forget your heating system is even running. The secret is Mitsubishi’s inverter technology, which gently adjusts output based on actual needs instead of the jarring on-off cycling of conventional systems.
Flexibility is another game-changer. A single outdoor unit can connect to up to eight indoor units, letting you customize temperature zones throughout your home. And don’t worry about our Pacific Northwest winters – Mitsubishi’s Hyper-Heating technology maintains 100% heating capacity down to -5°F and continues working in temperatures as frigid as -13°F.
I’m Colin Matei, owner of Clean Air Heating & Cooling in Bellingham, WA. Having personally overseen hundreds of Mitsubishi mini split installations throughout Whatcom, Skagit, and Snohomish counties, I’ve witnessed how these systems transform homes – dramatically improving comfort while slashing energy costs.
How Mitsubishi Mini Split Systems Work & Key Technologies
When I explain Mitsubishi mini split systems to homeowners across Bellingham, I often start with one simple fact: they work completely differently than traditional HVAC systems. Instead of generating heated or cooled air centrally and pushing it through leaky ductwork (where up to 30% of your energy dollars literally vanish into thin air), mini splits use a direct refrigerant circuit that transfers heat between indoor and outdoor units with remarkable efficiency.
The Inverter Advantage
The heart of every Mitsubishi system is its ingenious inverter-driven compressor. I like to tell my customers in Whatcom County, “Imagine your old HVAC system is like driving by constantly stomping on the gas pedal, then slamming on the brakes – while a Mitsubishi mini split is like setting your car to cruise control at the perfect speed.”
Traditional systems blast on at full power then shut off completely, creating those uncomfortable temperature swings we’ve all experienced. Mitsubishi’s inverter compressors, however, gently adjust their speed to deliver precisely the heating or cooling your space needs – maintaining your desired temperature within half a degree while sipping electricity. This remarkable precision is how these systems achieve efficiency ratings up to an astonishing 32.2 SEER2, more than double the federal minimum of 14 SEER2.
Hyper-Heating H2i Technology
If you live in the chillier parts of Skagit or Whatcom counties, you’ll appreciate this next innovation. Traditional heat pumps have always struggled in serious cold, losing heating capacity just when you need it most. Mitsubishi’s Hyper-Heating (H2i) technology changes everything by maintaining 100% of rated heating capacity down to -5°F and continuing to function even when temperatures plummet to -13°F.
This cold-weather performance comes from brilliant engineering: a flash injection circuit keeps refrigerant flowing optimally in frigid conditions, while the improved compressor design operates efficiently at temperatures that would cripple standard units. The system even features smart defrost cycles that minimize interruptions to your heating – keeping you toasty through our Pacific Northwest winters.
Zoning: The Ultimate Comfort Solution
One feature my customers absolutely love about Mitsubishi mini split systems is true zoning capability. With multi-zone setups, a single outdoor unit can connect to up to eight indoor units, each independently controlled.
This means your bedroom can be a cool 65°F while your living room stays at a comfortable 72°F. You can turn off conditioning completely in unused guest rooms, provide extra heating to naturally chilly basements, or adjust temperatures throughout the day based on how you actually use your home. It’s personalized comfort that traditional HVAC simply can’t match.
3D i-see Sensor: Smart Comfort
Some of our premium Mitsubishi models include the clever 3D i-see Sensor technology. This intelligent system constantly scans your room, detecting both occupancy and temperature variations. It can direct airflow toward or away from people (depending on your preference), automatically adjust settings when rooms are empty, identify and fix hot or cold spots, and optimize energy usage based on real-time conditions.
The technology is so smart it can even tell when you’ve left the room and automatically adjust to save energy – then return to your preferred settings when you come back.
Whisper-Quiet Operation
When I install Mitsubishi mini split systems in bedrooms or home offices, customers are often shocked by how quiet they are. At just 19 decibels on their lowest setting, these units are literally quieter than a whisper (which typically measures around 30 dB). You’ll feel the comfort without hearing the equipment – perfect for light sleepers or anyone sensitive to noise.
Dual Barrier Coating
Mitsubishi’s proprietary Dual Barrier Coating protects the internal components from dust, dirt, and grease accumulation. This thoughtful feature not only improves your air quality but also extends system lifespan, maintains efficiency over years of operation, reduces maintenance needs, and prevents those unpleasant odors that can develop in older air conditioning systems.
For homeowners interested in a deeper dive into the technical side, I recommend checking out our detailed explanation on How Do Ductless Mini Split Systems Work?. We also have great information about innovative indoor unit options like the 1 way ceiling cassette that offers flexible installation options for unique spaces.
At Clean Air Heating & Cooling, we’ve installed hundreds of these systems throughout Whatcom, Skagit and Snohomish counties, and I’m continually impressed by how Mitsubishi’s technology delivers both comfort and efficiency that conventional systems simply can’t match.
Best Mitsubishi Mini Split Models for 2024
After installing hundreds of systems throughout Northwest Washington, we’ve developed clear insights into which Mitsubishi mini split models work best for different homes and needs. Here’s our comprehensive breakdown of the top models available today:
Deluxe Hyper-Heat FS Series Mitsubishi mini split
The FS Series represents Mitsubishi’s pinnacle of efficiency and performance, making it our top recommendation for homeowners seeking the absolute best in comfort and energy savings.
The industry-leading 32.2 SEER2 efficiency rating and exceptional 13.5 HSPF2 heating efficiency make this model a true energy champion. With Hyper-Heating technology, you’ll enjoy 100% heating capacity even when temperatures drop to -5°F, and the system continues working down to a frigid -13°F – perfect for our Pacific Northwest winters.
The 3D i-see Sensor intelligently detects room occupancy and temperature variations, automatically adjusting airflow for maximum comfort. Plus, the Dual Barrier Coating keeps internal components clean, improving air quality and reducing maintenance needs.
One Bellingham homeowner told us after their FS Series installation: “Our home has never been more comfortable, and our winter electric bills dropped by nearly 60% compared to our old baseboard heating.”
For the ultimate performance package, we often recommend our Mitsubishi Mini Split Gold Package which features the FS Series with premium installation components.
Premium FH Series Mitsubishi mini split
The FH Series balances exceptional performance with advanced comfort features, making it a popular choice for homeowners seeking premium comfort without the highest price tag.
With up to 28 SEER2 efficiency rating, this model still delivers impressive energy savings. The double-vane airflow system provides precise air distribution, while the improved triple-action filtration system is a game-changer for allergy sufferers. A unique humidify mode during heating operation prevents that dry winter air feeling that’s common with other heating systems.
“The FH Series’ ability to maintain humidity during heating mode has eliminated the dry skin and static electricity problems we used to have with our forced air furnace,” reported a customer in Mount Vernon.
Available with the Hyper-Heat option and Energy Star certified across all models, the FH Series is ideal for homes with varying heating and cooling needs.
Standard GL Series Mitsubishi mini split
The GL Series is our most popular model line, offering an excellent balance of performance, reliability, and value that makes it perfect for most Northwest Washington homes.

The simple, neat design blends with most interiors, and the standard filtration system improves air quality without the premium price tag. Wi-Fi control capability is available with an optional adapter, giving you the convenience of smartphone control when you want it.
The GL Series forms the backbone of our Mitsubishi Mini Split Silver Package, which provides outstanding value for most Northwest Washington homes.
Ceiling Cassette MLZ Series
For homeowners who prefer their HVAC equipment to be virtually invisible, the MLZ Ceiling Cassette Series offers a sophisticated solution that integrates seamlessly with your home’s architecture.
These clever units flush-mount into standard 16″ joist spacing, making them practically disappear into your ceiling. The multi-directional airflow from a central location ensures even comfort throughout the room, and the easy-access service panel makes maintenance a breeze.
“Our architect recommended the MLZ Series for our open-concept living area, and we couldn’t be happier,” said a Snohomish County customer. “Guests don’t even notice it until we point it out.”
These units are particularly popular with builders and homeowners doing major renovations, as they’re perfect for spaces where wall-mounted units aren’t practical or aesthetically desirable. For more information on these innovative units, check out Mitsubishi’s 1 way ceiling cassette product page.
Floor-Mounted MFZ Series Mitsubishi mini split
The MFZ Series offers a unique solution for spaces where wall mounting isn’t ideal, such as rooms with sloped ceilings, dormers, or large windows.
With dual air discharge for improved circulation and quick-install mounting legs for simple installation, these units are particularly well-suited for attic conversions and spaces with architectural challenges. The compact design fits perfectly under windows, and the powerful airflow can effectively heat rooms from floor level – making them excellent replacements for inefficient baseboard heaters.
A customer in Anacortes with a converted attic space told us: “The MFZ unit fits perfectly under our dormer window and heats the entire space evenly, even with our sloped ceilings.”
The MFZ Series comes with an allergen filtration system and is Hyper-Heat compatible for reliable cold climate performance. Available in 9,000, 12,000, and 18,000 BTU capacities, there’s an option for nearly any challenging space in your home.
Comparison of Top Mitsubishi Mini Split Models
When helping homeowners throughout Whatcom and Skagit counties choose the right system, I often find that seeing models side-by-side makes the decision much clearer. Here’s how the top Mitsubishi mini split models compare:
| Model Series | Max SEER2 | HSPF2 | Sound Level | Key Features | Best For |
|---|---|---|---|---|---|
| FS Deluxe | 32.2 | 13.5 | 20-43 dB | 3D i-see Sensor, Dual Barrier Coating | Maximum efficiency, premium homes |
| FH Premium | 28.0 | 12.5 | 20-44 dB | Double vane airflow, Humidify mode | Allergy sufferers, comfort-focused buyers |
| GL Standard | 24.6 | 11.5 | 19-45 dB | Simple design, Reliable performance | Budget-conscious, most homes |
| MLZ Ceiling | 19.8 | 10.3 | 27-46 dB | Flush mount, Multi-directional air | New construction, hidden installation |
| MFZ Floor | 21.6 | 11.0 | 25-44 dB | Under-window mounting, Dual discharge | Attics, dormers, baseboard replacement |
Looking at this comparison, you’ll notice that even the “standard” GL Series offers impressive efficiency that far exceeds federal minimums. In fact, many of our Bellingham customers are surprised to learn that the most basic Mitsubishi mini split model is still about 75% more efficient than the average conventional system.
The sound level measurements are particularly interesting. While the range looks similar across models, experiencing the difference between 19 dB and 27 dB in person is quite remarkable. As I often demonstrate in our showroom, 19 dB is quieter than rainfall, while 27 dB is closer to a whispered conversation.
For most Pacific Northwest homes, the sweet spot tends to be either the GL or FH series, depending on your specific needs and budget. However, for those with larger homes or unique architectural features, a mix-and-match approach often works best – perhaps using the premium FS model in your main living area while installing the more economical GL units in bedrooms or less-used spaces.
One Ferndale customer recently told me, “I was skeptical about whether I’d notice the difference between the FH and GL models, but the FH’s double-vane airflow makes my living room feel so much more evenly comfortable.” These kinds of real-world experiences are why we take the time to thoroughly explain the differences rather than simply pushing the most expensive option.
Installation, Sizing & Operating Costs
Proper sizing and installation are critical to ensuring your Mitsubishi mini split system delivers its promised efficiency and comfort. As Diamond Dealers, we follow Mitsubishi’s exacting standards for every installation in Whatcom, Skagit, and Snohomish counties.
Proper System Sizing
The most common mistake I see when installing mini splits is improper sizing. It’s like buying shoes—too small and you’ll be uncomfortable; too large and you’ll waste money while still feeling uncomfortable!
An undersized system will struggle during our Pacific Northwest cold snaps, while an oversized system will constantly turn on and off (short-cycle), reducing both efficiency and comfort while potentially shortening system life.
For accurate sizing, we perform a detailed heat load calculation that considers everything unique about your home: room dimensions, insulation quality, window types, local climate data, home orientation, and even your family’s living patterns.
As a friendly rule of thumb for our Bellingham neighbors:
- Small rooms (100-250 sq ft): 6,000-9,000 BTU
- Medium rooms (250-500 sq ft): 9,000-12,000 BTU
- Large rooms (500-750 sq ft): 12,000-18,000 BTU
- Very large spaces (750-1,000+ sq ft): 18,000-36,000 BTU
But remember, these are just starting points! Your actual needs might differ based on your home’s specific characteristics. For more detailed guidance, check out our comprehensive guide on How to Size a Mini Split System.
Single-Zone vs. Multi-Zone Considerations
When designing your system, we’ll help you decide between single-zone and multi-zone options based on your specific needs.
Single-zone systems connect one outdoor unit to one indoor unit. They’re typically more efficient for individual applications and have a simpler installation with lower upfront costs. I often recommend these for additions, converted garages, or solving comfort problems in specific rooms.
Multi-zone systems allow one outdoor unit to connect to multiple indoor units (up to 8 with some models!). These are more economical than installing multiple single-zone systems and create a smaller footprint outside your home. They’re perfect for whole-home applications or multiple adjacent spaces that need conditioning.
“We initially wanted individual units for our bedrooms,” shared one Anacortes family, “but Colin showed us how a multi-zone system would save us money and look better outside our home. Best decision we made!”
Installation Requirements
A proper Mitsubishi mini split installation involves careful planning of several critical elements:
Line sets (the copper tubes connecting indoor and outdoor units) have specific requirements for length and height differences. Most residential models can handle 50-100 feet total length with height differences of 40-50 feet between units. We ensure proper insulation of all refrigerant lines and secure mounting to protect from damage.
Electrical requirements vary by system size. Smaller single-zone systems typically need a 115V/15-20A circuit, while larger systems require 230V/15-30A dedicated circuits. Safety features like proper disconnects are installed to meet code requirements.
Permits are essential! We handle all the paperwork for electrical permits, mechanical permits, and ensure compliance with local noise ordinances and setback requirements. This protects you from potential issues with inspections or home sales down the road.
Professional Installation Benefits
As Mitsubishi Diamond Dealers (the highest certification level!), our installation teams bring specialized expertise to your project. We’re not just installing equipment—we’re creating a comfort system that will serve your family for decades.
Our technicians are factory-trained and certified, following Mitsubishi’s exacting specifications that go well beyond minimum requirements. We use specialized tools for proper vacuum and refrigerant charging, ensuring your system operates at peak efficiency from day one.
The Diamond Dealer difference also extends to your warranty—you’ll receive the extended 12-year warranty instead of the standard 7-year coverage, providing additional peace of mind.
“The attention to detail during installation was impressive,” noted a recent customer in Mount Vernon. “The technicians took time to explain everything, positioned the units perfectly for airflow, and left my home cleaner than when they arrived!”
Learn more about our approach to Ductless Mini Split Installation or find a qualified installer through Mitsubishi’s Diamond Dealer locator.
Operating Costs and Savings
One of the most rewarding parts of my job is hearing from customers about their energy savings after installing a Mitsubishi mini split system. Throughout Northwest Washington, our customers typically report:
25-50% reduction in heating costs compared to electric resistance heating like baseboards or wall heaters. For a typical 2,000 square foot home in Bellingham, this can mean savings of $600-1,200 annually!
30-40% reduction in cooling costs compared to window units or central AC systems. While our summers are mild, those few weeks of heat can be much more comfortable without breaking the bank.
Additional savings come through zoning capabilities—no more heating or cooling unused spaces. Why pay to condition the guest room when nobody’s visiting?
We’re so confident in these savings that we offer a 25% utility savings guarantee. If your system doesn’t deliver, we’ll make it right.
Available Rebates and Incentives
The initial investment in a Mitsubishi mini split system becomes even more attractive when you factor in available incentives. Many utilities in Whatcom, Skagit, and Snohomish counties offer substantial rebates for high-efficiency heat pumps:
PUD rebates often range from $500 to $1,500 for qualified heat pump installations. Homes converting from oil or propane heating may qualify for special incentives that can exceed $2,000. Additional rebates are frequently available for homes with existing electric resistance heating.
There are also potential federal tax credits for high-efficiency systems that can provide additional savings on your tax return.
During your free consultation, our comfort advisors will identify all available incentives to maximize your savings and make your new Mitsubishi mini split system as affordable as possible. For many homeowners, these incentives can cover 15-30% of the total project cost!
The average installation in Washington state typically ranges from $4,000 for a simple single-zone system to $12,000 for a whole-home multi-zone solution—but your specific costs will depend on your home’s unique needs and the incentives available to you.
Maintenance, Troubleshooting & Warranty
Keeping your Mitsubishi mini split running smoothly isn’t complicated, but a little regular attention goes a long way toward ensuring years of efficient, trouble-free operation.
Essential Maintenance Tasks
Those beautiful wall units don’t just look good – they’re designed for easy maintenance too. The most important task is regular filter cleaning. While Mitsubishi officially recommends a two-week cleaning schedule, we’ve found that most homes in Whatcom and Skagit counties can get by with monthly cleanings during normal use. If you have pets or it’s pollen season, you might want to stick closer to that two-week recommendation.
Cleaning your filters is simple – power off the unit, pop open the front panel, slide out the filters, and either vacuum them or give them a gentle wash with mild soapy water. Just make sure they’re completely dry before putting them back in!
“The five minutes I spend cleaning my filters each month has kept my system running like new for years,” one of our Bellingham customers recently told us. “It’s so much easier than my old furnace ever was.”
Beyond the regular filter cleaning, your Mitsubishi mini split benefits from semi-annual maintenance that includes:
- Cleaning indoor coils and blower wheels to remove built-up dust
- Checking and clearing condensate drain lines (a common source of issues)
- Inspecting and cleaning the outdoor unit, removing debris and vegetation
- Checking refrigerant levels and electrical connections
Many of our customers opt for our professional Mini Split Cleaning Service, which thoroughly addresses all these points and more. For those who prefer the DIY approach, we’ve put together a comprehensive Mini Split Maintenance guide on our website.
Common Issues and Troubleshooting
Even the best systems occasionally need a little troubleshooting. Here are some common situations we encounter in Northwest Washington homes:
Defrost Cycles – During winter operation, your outdoor unit will periodically defrost itself. This is completely normal, but excessive defrosting can indicate problems. According to Mitsubishi technical support, “The most frequent defrost cycle should be once every 40 minutes.” If your system defrosts more often, it could be due to restricted airflow around the outdoor unit, snow accumulation beneath the unit, or in some cases, the system may need a firmware update.
Strange Noises – Some sounds are perfectly normal. Slight clicking or ticking happens as components expand and contract with temperature changes. You’ll also hear occasional whooshing sounds as refrigerant flows, especially during defrost cycles. Gurgling is typically just condensate draining away. However, if you hear loud rattling or grinding, it’s time to give us a call.
Water Leaks – A properly installed Mitsubishi mini split shouldn’t leak water inside your home. If you notice dripping, the condensate drain line might be clogged, improperly sloped, or in winter, possibly frozen. A quick inspection can usually identify the cause.
Control Problems – Before assuming there’s a system problem, try the simple fixes: replace remote batteries, ensure nothing’s blocking the signal to the indoor unit, or reset the remote by removing batteries for a minute. Many of our customers have switched to the kumo cloud Wi-Fi control system, which eliminates most remote control headaches while adding convenient smartphone control.
Uneven Comfort – If your room has hot or cold spots, check for obstructions blocking airflow, adjust the vane direction settings, or consider upgrading to a model with the 3D i-see Sensor that automatically detects and compensates for temperature variations in the room.
Warranty Coverage
One of the reasons we’re proud to be Mitsubishi Diamond Dealers is the exceptional warranty coverage they provide:
The standard Mitsubishi warranty includes 7 years of coverage on the compressor and 5 years on parts. But as certified Diamond Dealers, all Mitsubishi mini split systems we install automatically qualify for the extended 12-year warranty on both the compressor and parts. That’s among the best coverage in the industry!
“Having that 12-year warranty gave us such peace of mind,” shared one of our Mount Vernon customers. “It was a major factor in choosing Mitsubishi over other brands.”
Warranty registration within 60 days of installation is required to activate the full coverage, but our team handles this paperwork for you as part of our installation process.
Special Considerations for Northwest Washington
Our unique Pacific Northwest climate presents some specific challenges for heat pump systems:
Snow and Ice Management – For homes in the foothills or mountain areas of Whatcom and Skagit counties, we typically install outdoor units on wall brackets to keep them safely above snow accumulation. Hyper-Heat models include sophisticated defrost cycles, but they still need proper clearance to function optimally.
Coastal Considerations – For our customers in coastal areas and the San Juan Islands, salt air can be hard on outdoor equipment. We often recommend additional corrosion-resistant coatings and more frequent maintenance checks to ensure long system life.
The good news is that Mitsubishi mini splits are specifically engineered to handle our climate challenges, which is why they’ve become our most recommended comfort solution for homes throughout Northwest Washington.
Frequently Asked Questions about Mitsubishi Mini Splits
What SEER2 rating should I choose for the best balance of cost and efficiency?
When customers visit our Bellingham showroom, this is often their first question. For most Northwest Washington homes, we recommend systems with a SEER2 rating between 18 and 24. This sweet spot delivers excellent energy savings without the premium price tag of the highest-efficiency models.
In our climate, upgrading from an 18 SEER2 to a 24+ SEER2 unit typically pays for itself in 5-7 years through lower energy bills. If you’re planning to stay in your home long-term, that higher efficiency rating becomes an increasingly attractive investment with each passing winter.
That said, efficiency isn’t everything. Many of our customers find the premium features of higher-end Mitsubishi mini split models—like the 3D i-see Sensor that detects room occupancy or the improved filtration systems—worth the additional cost regardless of the efficiency rating. These comfort features can transform how your home feels day-to-day, which is hard to put a price tag on.
Can a Mitsubishi mini split be my primary heat source in sub-zero winters?
Absolutely yes—with the right model and proper sizing. Many of our customers across Whatcom, Skagit, and Snohomish counties have completely replaced their old oil, propane, or electric resistance heating systems with Mitsubishi mini splits as their sole heat source, even in areas that regularly dip below freezing.
The secret is selecting Hyper-Heat (H2i) models specifically engineered for cold climates. These remarkable systems maintain 100% of their heating capacity down to -5°F and continue working in temperatures as frigid as -13°F. For perspective, Bellingham’s record low is -7°F, meaning these systems can handle even our most extreme weather events.
For cold-climate installations, we typically recommend slightly oversizing the indoor units in primary living spaces to ensure toasty comfort on the coldest days. A multi-zone system helps ensure even heating throughout larger homes, preventing cold spots that can occur with single-zone setups.
The final piece of the puzzle is professional installation with cold-weather performance in mind. Our technicians optimize the refrigerant charge specifically for winter operation and position outdoor units to prevent snow buildup and ensure proper defrosting.
How long does a properly maintained Mitsubishi mini split last?
“Built like a tank” is how one of our long-time customers describes his 18-year-old Mitsubishi mini split that’s still running strong. With proper care, these systems typically last 15-20 years—significantly outlasting conventional HVAC equipment.
We have customers throughout Northwest Washington with original Mitsubishi systems installed in the early 2000s that continue to operate efficiently. This impressive longevity stems from several key factors:
First, the inverter technology dramatically reduces wear and tear on the compressor by avoiding the stress of frequent on/off cycles. Think of it like highway miles versus city driving on your car—steady operation is much gentler on mechanical components.
Second, Mitsubishi’s Dual Barrier Coating protects internal components from dust, dirt, and other contaminants that typically degrade performance over time. The high-quality materials and manufacturing standards further contribute to this exceptional durability.
Regular maintenance plays a crucial role too. Simple tasks like monthly filter cleaning and annual professional service visits can add years to your system’s life. We’ve noticed a clear correlation between maintenance frequency and system longevity among our hundreds of installations.
This extended lifespan dramatically improves your return on investment, especially when combined with the substantial energy savings these systems provide. When amortized over 15-20 years rather than the 8-12 years typical of conventional systems, the annual cost of ownership becomes remarkably affordable.
