Fast & Professional Furnace Repair

When your furnace fails, you need an immediate solution. Our certified technicians accurately diagnose and repair all gas, electric, and oil furnaces to safely restore your home's warmth.

Warning Signs

Common Furnace Problems

A malfunctioning furnace is a serious safety concern. If you notice any of these signs, turn your unit off and call our professionals immediately.

Blowing Cold Air

This often points to a malfunctioning limit switch, a dirty flame sensor, or an extinguished pilot light preventing burner ignition.

Strange Noises

Squealing, banging, or rumbling sounds indicate mechanical wear, such as a failing blower motor or loose internal components.

Yellow Burner Flame

A healthy gas flame should be crisp and blue. A flickering yellow flame indicates a dangerous mix of gas and oxygen, potentially creating carbon monoxide.

Short Cycling

If your furnace turns on and shuts off rapidly without heating your home, it is overheating, usually due to a severely clogged air filter.

Why Fix Your Furnace Now?

Postponing furnace repairs doesn't save money—it typically leads to massive breakdowns during freezing nights. Prompt attention ensures safety and efficiency.

    A cracked heat exchanger or blocked flue is deadly. We test for and eliminate CO risks.

  • Restore Consistent Warmth

    Stop dealing with freezing rooms and constantly adjusting the thermostat. Get even heat back.

    A repaired, correctly cycling furnace stops wasting expensive natural gas or electricity.

Furnace Repair FAQs

Repair costs vary widely depending on the issue. Replacing a simple flame sensor or capacitor is relatively inexpensive, while replacing a control board or draft inducer motor costs more. We always provide a flat-rate, upfront quote before any work begins so there are no surprises.

A burning dust smell is very common the first time you turn on your heater for the season, as it burns off settled dust. However, if the smell persists for more than a day, smells like burning plastic, or smells like rotten eggs (gas leak), shut the system off immediately and call us.

First, check your thermostat to ensure the fan is set to 'Auto' rather than 'On'. If it's set correctly, the issue could be an unlit pilot light, a dirty flame sensor preventing the burners from igniting, or a triggered limit switch. This requires professional diagnosis.

A cracked heat exchanger is extremely dangerous as it leaks carbon monoxide. Signs include soot buildup inside the furnace, a yellow (rather than blue) burner flame, or your home's CO detectors going off. Only a professional inspection can confirm a crack, which typically requires a full furnace replacement for safety.
