Keeping Loudoun County Homes Warm Through Winter

Brick Street Plumbing Heat & Air offers furnace repair and installation in Leesburg, VA, plus the maintenance, diagnostics and safety checks that keep a furnace running all winter. When the heat goes out, call us any time. We are available 24/7 for emergency furnace calls and never charge overtime, so a breakdown on a cold January night does not come with a bigger bill. A licensed technician will find the fault and tell you plainly whether repair or replacement makes more sense.

Furnaces here work hard from late fall into early spring, and the problems we see most often are worn igniters, dirty flame sensors, failing blower motors, clogged filters and tripped limit switches. Older systems can also develop cracked heat exchangers or venting problems, which is why every visit includes a look at safety. We work across Loudoun County and the rest of Northern Virginia, and in nearby Maryland and West Virginia towns. If your home heats with hot water instead of forced air, see our boiler repair service.

BEFORE YOU CALL

Three Quick Checks When the Heat Stops

Some no-heat calls end before a technician arrives. First, make sure the thermostat is set to heat and the setpoint is above room temperature, and replace its batteries if the screen is blank. Second, check the furnace filter. A badly clogged filter can trip the high-limit switch and shut the burners off. Third, confirm the furnace switch, which often looks like a light switch near the unit, is on, and that the breaker has not tripped. If all three look fine and the house is still cooling off, call for furnace repair. If you smell gas, leave the house first and call from outside.

SAFETY

Why Every Furnace Visit Includes a Safety Look

A gas furnace burns fuel inside your home, and the products of that combustion have to leave through the flue. On each call our technicians check for gas leaks at the valve and connections, confirm the venting is intact and drafting properly, and look over the heat exchanger and burners. These checks matter most on older furnaces and after a long idle summer. Every home with fuel-burning equipment should also have working carbon monoxide alarms. The same care carries into new installs. When we replace a furnace, we size it to the house instead of copying the old unit, check that the ductwork and return air can handle the airflow, set up the venting for the new equipment, and test gas pressure and safety controls before we leave. If a heat pump or dual-fuel setup suits your home better, we will lay out that option too, and our heat pump services page covers it in more detail.

Frequently asked questions

Why does my furnace turn on and then shut off after a few seconds?

A dirty flame sensor is the most common reason. The sensor confirms the burners lit, and when it is coated with residue the control board cannot see the flame and shuts the gas off as a safety measure. Other causes include a clogged filter tripping the limit switch, a venting problem, or a failing pressure switch. Cleaning a flame sensor is a quick repair, but a technician should confirm that is really the cause.

Is it safe to run my furnace if I smell gas?

No. If you smell rotten eggs near the furnace or anywhere in the house, do not touch light switches or the thermostat, get everyone outside, and call your gas provider's emergency line or 911 from outside the home. Once the gas side has been made safe, call us to inspect the furnace, find the leak point and make the repair before the system is put back into service.

How long should a furnace last before replacement in Leesburg?

There is no fixed number. Many gas furnaces give well over a decade of service with regular maintenance, though the real answer depends on how well the unit was installed and cared for. Signs that replacement is getting close include frequent repairs, uneven heating, a cracked heat exchanger, rising gas use and yellow or flickering burner flames. When a technician finds one of these, we explain the repair option and the replacement option side by side.

When should I schedule furnace maintenance?

Early fall is the best time, before you need heat every day. A tune-up then catches weak igniters, dirty sensors and worn blower parts while you still have time to fix them calmly. It also gives the technician a chance to check venting and look for gas leaks after the furnace has sat unused all summer. Change the filter regularly between visits.

Can you replace a furnace and air conditioner at the same time?

Yes, and it often makes sense when both are aging. The furnace blower moves air for the air conditioner as well, so replacing them together lets us match the indoor coil, blower and outdoor unit so they work as a set. If only one is failing, we will tell you honestly whether the other still has life left before you decide.
