Heating Repair in Northern Virginia

The System Is Running, But the Air Is Cold – If your system is blowing air, but the house isn’t warming up, it’s likely a failed igniter, clogged burner, broken heating element, or refrigerant problem in heat pumps. You’re using energy, but not getting heat. We isolate the heat source, repair or replace faulty parts, and make sure the unit is actually producing warm air—not just moving it.

Only Some Rooms Are Getting Heat – Uneven heating happens a lot in two-story homes or homes with additions. It’s usually caused by airflow restrictions, bad zoning dampers, or a failing blower. We check air distribution room-by-room, identify where it’s being blocked or imbalanced, and fix the airflow path so every room heats consistently.

The Thermostat Isn’t Working or Is Inaccurate – When the thermostat is off, your whole system is off. It might be a wiring problem, a dead sensor, or a control board issue. We test communication between the thermostat and system, recalibrate or replace it, and can upgrade you to a smart model for better control if needed.

Short Cycling: System Starts, Then Shuts Down – Short cycling usually points to overheating, pressure imbalance, or a dirty flame sensor. Left unchecked, it can wear out the system fast. We find the cause, stop the on-off cycle, and protect the system from excess stress and inefficiency.

Loud Noises from the Unit – Banging, whining, rattling—none of these are normal. They usually mean loose components, worn bearings, delayed ignition, or blower issues. If your system’s making noise, we shut it down, inspect all moving parts, and get it operating quietly and safely again.

Frozen Heat Pump or Outdoor Unit – In freezing weather, outdoor heat pumps can ice over if the defrost system isn’t working. That stops the entire heat transfer process. We check refrigerant levels, the reversing valve, and the defrost cycle to clear the issue before it burns out your compressor.

Pilot Light or Ignition Issues – If your furnace won’t ignite—or keeps shutting off—it’s likely a bad igniter, flame sensor, or gas valve. These are common failure points in older systems. We’ll safely test and replace the failed component so your heat comes on and stays on.

Boiler Pressure Issues – We specialize in diagnosing and fixing low boiler pressure, ensuring your system operates efficiently and your home stays warm. Whether it’s a leaking valve or air trapped in the system, we’ll get your boiler back to optimal performance.
