When to Call for AC or Furnace Repair

Most heating and cooling failures start small. These are the signs worth a call.

  • Rooms that never reach temperature
  • Higher bills than last season
  • Burning or musty smells
  • System short cycling
  • Strange noises at startup

None of these fix themselves, and most get more expensive with time. If you notice one, call the office and we will take a look.

Before you call, check two quick things. Make sure the thermostat is set to the right mode, and look at the air filter. A clogged filter can shut down an air conditioner or a furnace, and swapping it may solve the problem.

Common Air Conditioner Repairs

Capacitors and contactors are among the most common AC repairs. They wear out after years of starting the compressor, and a failed one can leave the outdoor unit humming without running.

Refrigerant leaks come next. A system low on refrigerant cools poorly and can freeze at the indoor coil, so we find and repair the leak instead of just adding more. Clogged filters, dirty condenser coils, and blocked drain lines account for much of the rest.

What Usually Goes Wrong With a Furnace

A furnace that runs but blows cold air often has an ignition or flame sensor problem. A furnace that will not start at all may have a failed control board, a tripped safety switch, or a thermostat issue.

Blower motors, belts, and clogged filters cause noise and overheating, and they tend to show up during the first long cold stretch of the season. Every furnace repair includes a check of the heat exchanger and venting, because those parts protect your family from exhaust gases.

What to Expect When We Arrive

Each AC and furnace repair visit follows a simple order.

Check-in

We ask what the system has been doing and listen to your concerns.

Full inspection

We check the parts most likely to fail along with the safety components.

Options and cost

You get a clear explanation and the price before any repair starts.

Repair and confirm

We make the repair and run the system through a full cycle.

Our technicians are background-checked and NATE certified, so you know who is in your home. Call the office or fill out the form to book a visit.

Emergency Heating and Cooling Calls

Systems rarely fail at a convenient time. Our phone is answered 24/7, and emergency calls are handled based on the weather and how severe the situation is, so a home without heat in a hard freeze or without cooling in dangerous heat moves up the list.

Field hours run from about 7 AM to 8 PM. Outside those hours, we will talk through what is happening and give you an honest answer on timing. If you smell gas, get everyone outside and call your gas utility before anything else.

How Repair Pricing Works

Repair pricing depends on the problem, the parts, and the system you have. We diagnose first, then give you the cost, so you never approve work without knowing the number.

The repair-or-replace question comes down to the age of your system, the cost of the repair, and how often it has needed work. A newer system with one failed part is almost always worth fixing, and we will tell you when it is not.

When repair costs start stacking up on aging equipment, we lay out the option of AC installation and replacement or furnace installation and replacement next to the repair so you can compare honestly. Financing is available through Hearth, and first responders and military members get 10% off.

To keep repair bills down in the first place, schedule AC maintenance each spring and furnace maintenance each fall.
