Common causes include low refrigerant, a dirty filter or coil, a frozen coil, or a failing compressor. We'll diagnose the exact cause before recommending a fix.

Usually restricted airflow from a dirty filter or coil, or low refrigerant. Turn the system off to let it thaw, then call us to find the root cause.

With regular maintenance, most AC systems last 12 to 15 years. Beyond that, replacement often costs less than ongoing repairs.

Yes. We locate and repair leaks and recharge your system to the correct level — simply topping off refrigerant without fixing the leak is only a temporary patch.

If your unit is over 10 to 15 years old, needs frequent repairs, or drives high energy bills, replacement may save you money. We give you an honest recommendation either way.

It could be a thermostat setting, a dirty filter, a pilot or ignition issue, or a safety lockout. We'll pinpoint the cause and fix it right.

Gas and electric furnaces, heat pumps, and air handlers — repair, maintenance, and replacement for all major brands.

A heat pump both heats and cools efficiently, making it a great fit for our East Tennessee climate. We'll help you decide if it suits your home.

With regular maintenance, most furnaces last 15 to 20 years. If yours is older and struggling, it may be time to consider replacement.

A cracked heat exchanger or poor combustion can leak carbon monoxide. Annual maintenance checks for safety, and we recommend a working CO detector in every home.

Yes. Heating and cooling don't fail on a schedule, so call (865) 336-0176 and we'll respond as fast as we can.

Turning on and off too often can come from an oversized system, a dirty filter, a failing thermostat, or a refrigerant issue. We'll diagnose and correct it.

A burning smell can be dust or an electrical issue; a musty smell often means mold or moisture in the system. Both are worth a professional look.

Rattling, buzzing, or grinding can signal loose parts, a failing motor, or debris. Don't ignore new noises — early repair prevents bigger failures.
