When the Heat Stops Working, We Get It Back
A failing furnace can be frustrating — especially when your home is cold and your family’s comfort is on the line. At CRS Heating and Air Conditioning, Inc., we specialize in fast, honest furnace repair. Whether the system won’t turn on, makes strange noises, or just isn’t keeping up, we’ll figure it out and get you warm again.
We service all major brands and furnace types, including older systems that many companies won’t touch.

Common Furnace Problems We Fix
Furnaces can fail in a lot of ways. You might notice cold air coming from the vents, a system that turns on and off constantly, or a burning smell when the heat kicks in. Sometimes it’s a safety shutoff. Sometimes it’s something simple.
We’ll check the whole system — ignitor, flame sensor, blower motor, control board, and safety switches — and explain what’s happening in clear terms.
