Heating and Cooling Questions

What people ask us

1. When is a furnace problem a safety problem?

   Gas smell, carbon monoxide alarm, or a burning smell that will not fade. For gas or carbon monoxide, leave the house and call from outside.

2. How much does HVAC repair cost?

   Across the U.S., many repairs run $150 to $900. Motors and compressors cost more. New AC systems often run $4,000 to $9,000.

3. What can I safely do myself?

   Thermostat, breaker, furnace switch, filter, outdoor unit debris and snow on vent pipes. Stop there.

4. What should I never do?

   Add refrigerant. Touch capacitors. Work on gas parts or wiring.

5. How do I choose a provider?

   License, insurance, clear visit fee, written estimate, real warranty. Missing any? Keep looking.

6. What are the biggest red flags?

   Today-only prices, no written estimate, scare talk without proof and refusing to show the failed part.

7. Should I get more than one estimate?

   For big jobs like replacement, yes. For a small repair with a clear cause, one is often enough.

8. Does Cometaxi Heating & Air do the work?

   No. Cometaxi Heating & Air is a referral service. Independent providers do the work.
