Common questions
Should I repair or replace my furnace?
It depends on age, the cost of the repair and how well the furnace runs. A furnace past 15 to 20 years old with a costly repair is often better replaced. We give you honest numbers, and install estimates are free.
How long does a repair take?
Many repairs finish in one visit when the part is on the van. If a part has to be ordered, we tell you before you decide.
