AC failure can cause a panic, especially if it happens during the hottest part of summer and the homeowner has to make a last-minute service call. By taking a proactive approach and scheduling routine checkups, one can keep their central air unit functioning as it should. Below is a list of the five main causes of HVAC failure, which customers can avoid by having preventive maintenance done by AA Temperature Services Inc.
Faulty Thermostat
A poorly functioning thermostat can cause Carrier Air Conditioners to work inefficiently or not at all. However, this cause is commonly overlooked when diagnosing problems. Homeowners should ensure that the tech checks the thermostat for debris and that they’re periodically calibrated for better accuracy.
Compressor Problems
The AC compressor is the engine of the system. A tripped breaker or blown fuse may be an early indicator that the compressor could fail. Some compressors are equipped with internal switches that shut the unit off if it’s overtaxed. Homeowners can prevent this by hiring a tech to configure the equipment, rather than turning it all the way up for quick cooling. Compressor fixes are costly and mean significant downtime, and maintenance should be included in routine checkups.
Blown Fuses
The fuse’s job is to regulate the flow of current to the unit, and they’re critical in preventing severe damage. The AC repair tech should check the fuses and replace them as necessary; this preventive maintenance step can save considerable expense later on.
Dirty Filters
Anything that keeps air from flowing freely through the system is a threat to its optimal performance. A dirty or clogged air filter will cause the HVAC system to overwork itself, blow fuses and damage other parts. Homeowners should replace filters on a regular basis, and they should consider that a dirty filter is a serious health hazard.
Poor Drainage
A failing condensation pump can cause the overflow safety valve to turn the unit off to prevent damage. This pump is normally turned on via a float switch when water levels become too high. When the unit is serviced, the tech will check the condensation pump and ensure that the float switch isn’t keeping the pump from coming on.
Most of the signs of AC failure are relatively easy to spot, and can be resolved with proper upkeep. By managing the maintenance schedule and getting routine service, a homeowner can keep Carrier Air Conditioners working well throughout its lifespan.
