- The pilot light or ignitor will not stay lit
- The furnace is 15+ years old and needs repairs most winters

Replacing a furnace? Here is the process.
Home visit & sizing
We check your ductwork, venting, and square footage so the replacement furnace is sized right, not just matched to the old model number.
Flat-rate quote
One written price before equipment is ordered. No surprise line items on install day.
Install day
Most furnace swaps are done in a day, with the mechanical room left as clean as we found it.
Safety check & warranty
We test the combustion and safety circuits before we leave, register the manufacturer warranty, and back our labor for a year.
Furnace safety is part of every visit, not an upsell.
Every furnace tune-up and repair includes a check of the heat exchanger, venting, and safety-shutoff circuits. If something needs attention, we will show it to you and explain the fix in plain language before we do anything.
