Furnace Repair FAQs

When should I change my furnace filters?

Plan to change your furnace filters every 60 days, or even sooner if you have pets or a serious dust issue. Your furnace can overheat and break down without clean filters, so make sure you take care of this task.

Do I have a carbon monoxide leak?

Carbon monoxide is an odorless and tasteless gas, but it’s also poisonous. The only way to know if you have a leak is with a carbon monoxide detector. 

Why is my home not getting warm when my furnace is on?

Make sure your thermostat is set correctly. If it is, and your furnace isn’t getting the job done, it may indicate you need to schedule a repair.
