A functioning central air conditioning system is the difference-maker when the temperature heats up. But when your AC begins to blow warm air, produce odd noises, or have trouble keeping up, it's not just a nuisance—it's an indication that something has to be fixed.
Common Central AC Issues We Repair
Air conditioners do their best to make homes comfortable, but eventually, components wear out and efficiency is lost. We've seen it all when it comes to AC problems, and some of the most common issues we repair are:
✔️ Poor Airflow – If your vents aren't blowing out enough cool air, it may be a dirty filter, malfunctioning blower motor, or clogged ducts.
✔️ Warm Air Rather Than Cold – Low refrigerant levels, a bad compressor, or thermostat problems can all cause warm air to blow through the vents.
✔️ Constant Cycling – An AC that cycles on and off too frequently may have an airflow blockage, a thermostat problem, or be the incorrect size for the room.
✔️ Strange or Loud Noises – Grinding, banging, or hissing noises usually indicate that the motor, fan, or refrigerant lines are experiencing problems.
✔️ Water Leaks Around the Unit – Frozen coils or clogged drain lines can create excessive moisture and water damage.
✔️ Increased Energy Bills – If your AC is running harder than normal, it might be laboring because of worn-out parts or a refrigerant leak.
Catch these issues early to avoid more expensive repairs in the future. Our technicians are experienced at diagnosing and repairing AC issues promptly so you can enjoy comfort without unwarranted anxiety.
