My HVAC equipment is frozen, what should I do?

Turn off your system; it needs to thaw out before a certified technician can assess the issue.

How do I turn my furnace off?

A furnace can be turned off by setting the thermostat to OFF.

How often should I change my furnace filter?

Furnace Filters should be changed once a month, year-round.

Do I need annual maintenance on my HVAC equipment?

Yes, maintenance is not only necessary to extend the life of your equipment and prevent unexpected breakdowns. Maintenance is also required by most manufacturers in order to maintain product warranties.

Can I still use my furnace with a cracked heat exchanger?

No, this is incredibly dangerous. A cracked heat exchanger produces carbon monoxide that could leak into your home.
