Which Furnace Service Do You Need?

Four services cover almost every furnace call. Find the row that fits your furnace, and ring us if you are unsure which one applies.

Furnace repair If the heat has gone out, furnace repair is the visit you want: the technician traces the fault and quotes the job before starting.

Furnace tune-up A yearly furnace tune-up catches small problems before they turn into a no-heat call, and the fall is a quieter time to book it than the first cold snap.

Furnace installation and replacement If the furnace is past saving, furnace installation starts with a free estimate that shows your options and the price.

Maintenance plan Our VIP maintenance plan puts the seasonal visits on a schedule so you do not have to remember them.

Gas, Oil and Electric Furnace Service

Furnaces differ by fuel, and the visit changes with them. Tell us which type you have when you book, and the right technician arrives prepared.

Gas furnace service Our gas furnace service includes repair, tune-ups and replacement for homes on either side of the Potomac. Gas furnaces involve fuel and combustion, so we treat any gas smell as a reason to leave the house first and call second.

Oil furnace service Oil furnaces are part of what we service, from Fairfax to Bethesda. If your home heats with oil, say so when you call and we will book the visit accordingly.

Electric furnace service Electric furnaces burn no fuel, so service centers on the electrical side of the system. We repair them, tune them up and install them.

Not sure what you have? Describe the unit or give us the brand and model, and we will confirm the type before the visit.

24/7 Emergency Furnace Service

A furnace rarely quits at a convenient hour. Our emergency furnace service in Northern Virginia and Maryland is staffed around the clock, every day of the year, including holidays and long weekends.

When to call at night Call straight away if the furnace dies on a cold night, a home with young children, older relatives or pets is losing heat, or the system shuts down repeatedly and will not stay on.

What to have ready Tell us whether the furnace burns gas, oil or electricity, what it was doing when it stopped, and the brand if you know it. That lets us plan the visit before we arrive.

Safety comes first If you smell gas or a carbon monoxide alarm sounds, get everyone outside and follow the safety steps on our furnace repair page before you phone us.

What Affects the Cost of a Furnace Visit?

The price of furnace service depends on which service you book and what your furnace needs, so we quote after the technician has looked at it. For a broader view of typical spending, our furnace repair and cleaning cost guide breaks down what drives the bill.

The service you book Maintenance, a repair and a replacement sit at very different price points, so start by deciding which one matches your situation.

The furnace itself Fuel type, brand, age and condition all shape what a visit involves.

What needs fixing A minor part and a major component do not cost the same, and the diagnosis tells you which one you are dealing with.

Price before work Once the technician has found the issue, you are told the cost and choose whether to proceed.
