HVAC FAQs

Properly maintaining most heating and cooling equipment will last 12 to 15 years. To maximize the service life of your HVAC system, change the air filter often, schedule repairs as soon as you notice a problem, and don’t skip your annual HVAC maintenance appointments.
To avoid the inconvenience of a service call, make sure your thermostat is working, set correctly, and has fresh batteries before calling a professional for HVAC repairs. Ensure the air filter is not clogged, and remove any furniture or other items blocking HVAC vents. Finally, try resetting the system by turning its breaker off, then back on.

Blue Frost checked my furnace and did a very thorough job. Tech was very good and took his time checking all components of the furnace and explaining what he was doing in terms I could understand. I highly recommend Blue Frost.
