Homeowners' pick for heating and cooling across Virginia and the Mid-Atlantic

Gas Furnace Repair in Alexandria, VA

If you smell gas, leave the house first, call 911 or your gas utility from outside, and call us after that. With the house safe, gas furnace repair in Alexandria usually means testing the igniter, flame sensor, pressure switch and gas valve in order until the failure shows itself. Short cycling and a furnace that lights then quits after thirty seconds are the two calls we run most in older brick colonials. Reach us by phone or through the quote form.

What brings Alexandria homeowners to this job

The furnace clicks, then nothing happens Ignitor, flame sensor or control board lockout
It runs for two minutes and shuts off, over and over Short cycling from a dirty flame sensor, blocked flue or restricted airflow
Air is coming out of the vents but it feels cool Burners not lighting, or the blower running on a fan setting

What gas furnace repair involves

A gas furnace repair starts with watching the unit try to run through a full heating cycle. We follow the sequence the way the furnace does it: call for heat, inducer, pressure switch proof, igniter, gas valve, flame sense, blower. Whatever step it stalls on tells us where to look. Older homes across the region often have ducts running through vented crawlspaces, so we also check what is happening downstream, because weak airflow at the registers can look like a furnace fault when the duct is the problem.< /p>

What we check and replace

Common repairs include flame sensors that have gone sooty, cracked or weak hot surface igniters, failed inducer motors, blocked condensate traps on high efficiency units and pressure switches that will not prove because a flue or drain is restricted. We inspect the heat exchanger, wiring, limit switches, the gas valve and the blower motor and capacitor. We check flue termination and combustion air, and we clean and test rather than guessing at parts. You get told what failed and why before anything is replaced.

How we decide repair is the right call

We weigh the age of the furnace, what else on it is worn, and whether the repair returns the system to safe, reliable heat. A twelve year old furnace needing one igniter is worth fixing. A furnace with a cracked heat exchanger is a safety shutdown, not a repair, and we will say so plainly. If damp crawlspace conditions have rusted the cabinet and drain assembly, we talk about that too. You decide with real information, and we will quote both paths.

Gas Furnace Repair in Alexandria — quick answers

My furnace lights then shuts off after a minute. What is that?

That pattern usually points to flame sensing, a restricted flue or an overheating limit trip from poor airflow. Change the filter and open closed vents. If it repeats, book a furnace repair so we can read the fault codes.

Is a yellow or lazy burner flame a problem?

It can indicate incomplete combustion, which raises carbon monoxide risk. Do not adjust anything yourself. If an alarm sounds or you smell gas, leave the house, call 911 or the gas utility, then call us for heater repair.

How soon can you get to my Alexandria home?

Call us and we will give you the first available window rather than a vague promise. During July and August heat waves, AC repair calls stack up, so morning calls usually get same-day or next-day attention. Parking is tight in Old Town and some condo buildings need a service elevator reserved, so tell us about that when you book and we will plan the visit around it.

How it works

Step 1
Tell us the symptom
Call or fill in the form and describe what changed. Warm air, short cycling, a smell, water near the indoor unit. Details like that help us load the right parts before we leave.
Step 2
We diagnose the whole system
We check the thermostat, the indoor unit, the outdoor unit and the ductwork, including runs in crawlspaces where damp air and loose joints quietly cause weak airflow and long run times.
Step 3
You approve the fix
We explain what failed, what it takes to repair it, and what we would watch next season. Nothing gets replaced without your yes, and we clean up before we leave.

Why homeowners call us

Humidity is our home groundMuggy summers and damp shoulder seasons drive most of the calls we take. We look at moisture and airflow together, not the cooling number alone, because a clammy house often means a sizing or duct problem.
Crawlspace ducts get checkedOlder homes across the region run supply ducts through vented crawlspaces. Crushed flex, disconnected boots and soaked insulation show up constantly, and we get under the house to look instead of guessing from the register.
Heating and cooling bothSame crew for air conditioning repair in July and heating repair in January. We know how your furnace, heat pump and air handler share ducts and a blower, so one visit covers the whole system.
Plain talk on repair or replaceWhen a repair makes sense, we repair it. When a system is failing in ways that will keep costing you, we say so and explain why, then leave the decision with you and your timeline.
