Not enough heat
If your furnace is on but not giving off enough heat, it may have a clogged, dirty air filter — one of the leading causes of a furnace breakdown.

Drastic temperature changes
If your furnace can't regulate your home's temperature, it could be a thermostat failure or malfunction. Thermostat issues cascade into fan, pilot light, power or gas problems and ruin your home's comfort.

Pilot light or ignition problems
If your furnace isn't turning on at all, a common explanation is the pilot light or electronic ignition. A flickering pilot may seem minor, but it causes unnecessary wear and drives up your monthly utility bill.

The furnace won't turn on
The most common causes are restricted airflow and an overheated heat exchanger. Our team will diagnose the exact problem and give you a transparent quote for fixing or replacing the unit.

A broken blower fan
The fan is the part of a furnace blower motor that breaks most often. Damage to it stops airflow moving across the heated coils, which leaves you with uneven heat throughout the house.
