Expert HVAC Services in Spartanburg, SC 29301 - Aire Service Heating & Air Condition

This is a common issue during our hot summers and often stems from a refrigerant leak, a frozen evaporator coil, or a failing compressor. Restricted airflow from a dirty filter or blocked vents can also cause it. Our technicians will perform a thorough diagnostic to pinpoint the exact cause and provide a repair that restores full cooling power to handle Spartanburg's heat.

A faulty reversing valve, crucial for switching between heating and cooling modes, often shows itself as your system blowing lukewarm air, being stuck in one mode, or making a distinct hissing noise. Given our climate where heat pumps are used frequently, this part can wear. We can test the valve's operation and replace it if needed, restoring your system's proper function for all seasons.

The single most impactful step is changing your air filter regularly, typically every 1-3 months. A clean filter maintains proper airflow, which prevents your AC from overworking and freezing up in summer and helps your heat pump run efficiently year-round. We recommend a professional tune-up twice a year—in spring and fall—to catch small issues like refrigerant levels or electrical connections before they lead to a major breakdown.
