Gierer Heating & Cooling - Saint Louis's Best HVAC Services

Common signs in St. Louis include the system blowing cool air when set to heat (or warm air when set to cool), the unit not switching modes properly, or unusual hissing sounds from the outdoor unit. This valve is crucial for our seasonal temperature swings. If you notice these issues, contact us for a prompt diagnosis and repair to prevent further system strain.

Yes, a failed outdoor fan motor is a serious issue, especially during our hot, humid St. Louis summers. Without the fan, the compressor can overheat and fail, leading to a much more costly repair. If the fan isn't running, turn the system off to prevent damage and call us immediately. We keep common motor parts in stock for faster repairs to restore your cooling.

Saint Louis's wide temperature ranges and high humidity put extra stress on HVAC components like fan motors and valves. Our thorough maintenance includes cleaning coils, checking electrical connections, lubricating moving parts, and testing system operation. This proactive service helps catch small issues before they become major breakdowns, improves efficiency to lower your bills, and extends the life of your equipment.
