Our experienced technicians have seen it all and are equipped to handle a wide range of heating and cooling issues.

- AC Not Cooling or Blowing Warm Air: Often caused by low refrigerant, a failing compressor, or dirty coils struggling against Georgia’s humidity.
- Furnace Fails to Ignite or Heat: This can stem from a faulty ignitor, a malfunctioning thermostat, or gas supply issues.
- Strange Noises or Odors: Banging, squealing, or grinding sounds can indicate loose parts or serious mechanical problems, while musty smells may point to moisture or mold buildup.
- System Short Cycling: When your unit turns on and off too frequently, it could be a sign of an oversized system, a clogged air filter, or electrical problems.
- Weak or No Airflow: Blocked filters, obstructed ductwork, or a failing blower motor are common culprits that restrict air from reaching your rooms.
- Thermostat Malfunctions: An inaccurate or unresponsive thermostat can prevent your system from maintaining the desired temperature.
