I have had many dealings with contractors over the past 50 years. Clean Air Comfort Systems recently installed a mini split system heat pump to replace our electric baseboard heat system. While it is to early to determine the operating efficiency, I am pleased to report this as the first 5 star experience I've ever enjoyed.

Always good service from technicians to their customer service. My technician today for my yearly service was Easton. He was personable, knowledgeable and familiar with my units. He spend extra time problem solving an issue I had and advising me of solutions. All the technicians that have provided service over the years have been great. I recommend Clean Air to anyone for quality service!

FAQs

Mini-Split Installation & Replacement

If your mini-split is over 10–15 years old, needs frequent repairs, or isn’t keeping your home comfortable, replacement is often the smarter long-term option. New systems are significantly more energy-efficient and reliable, which can reduce monthly costs and eliminate ongoing repair headaches.

Mini-split installation typically ranges from $4,000 to $15,000+, depending on the number of zones, system size, and installation complexity. The best way to get accurate pricing is with an in-home consultation so we can design the right system for your space.

Most mini-split installations are completed in one day, though multi-zone systems or more complex layouts may take longer. Our team will give you a clear timeline before work begins.
