Furnace Testimonials

Rated 5 out of 5
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

Furnaces

If your furnace is under 15 years old and the issue is isolated, a repair is often the most cost-effective option. Frequent breakdowns, rising energy bills, uneven heating, or major component failures may indicate replacement is the smarter long-term choice. Our technicians walk you through both options so you can decide with confidence.

Yes. If your furnace stops working during cold weather, emergency service may be necessary — especially if your home loses heat completely or safety systems shut the unit down.

We recommend professional furnace maintenance once per year, ideally before winter. Regular tune-ups improve efficiency, reduce breakdown risk, and extend the life of your system.

A furnace tune-up includes inspecting and cleaning critical components, testing safety systems, checking airflow, and verifying proper operation — all with clear recommendations and no surprises.

Most furnace installations are completed in one day. After installation, we fully test the system and walk you through operation, thermostat use, and maintenance basics before we leave.
