Frequently Asked Questions
How much does furnace repair cost?
Most furnace repairs in the DMV area cost between $150 and $700. Simple fixes like an ignitor replacement run $150-$300, while blower motor or gas valve repairs can be $400-$700. We provide an exact quote before starting — no surprises.
Why is my furnace blowing cold air?
Common causes include a dirty air filter restricting airflow, a malfunctioning thermostat, a pilot light or ignitor failure, or a cracked heat exchanger. Our technicians diagnose the root cause and explain your options before proceeding with any repair.
Is a cracked heat exchanger dangerous?
Yes. A cracked heat exchanger can leak carbon monoxide into your home — a serious safety hazard. If we detect a cracked heat exchanger, we’ll explain the situation honestly and help you weigh repair vs. replacement options. Every JDL furnace repair includes a free CO safety check.
How often should I replace my furnace filter?
Most standard 1-inch filters should be replaced every 30-90 days, depending on household factors like pets, allergies, and occupancy. A clogged filter forces your furnace to work harder, increasing energy bills and wear on components.
Do you repair heat pumps too?
Absolutely. Our technicians are trained on all heat pump systems — air-source, mini-splits, and dual-fuel configurations. We service Carrier, Lennox, Trane, Goodman, Mitsubishi, Daikin, and all other major brands.
