The Most Common Air Conditioning Problems
It’s common for an air conditioning system to fail to operate at the beginning of the cooling cycle.
Modern air conditioning systems are usually reliable, requiring minimal maintenance and providing homes with cool air to stay comfortable throughout summer. However, like all major appliances, an air conditioner can develop problems, making the home extremely uncomfortable. Homeowners should consider the most common problems that air conditioning units face to quickly identify problems or even avoid them altogether.
The unit does not turn on
It’s common for an air conditioning system to fail to operate at the beginning of the cooling cycle. If the thermostat is defective or not appropriately set, it can prevent the system from turning on. If this is causing the problem, the issue can likely be resolved independently. Check the thermostat and make sure that it’s set to cool. If the thermostat is automated, make sure the timer is not set to be off during this period. An HVAC contractor may be needed to re-calibrate the home’s thermostat.
Another reason the unit may not be turning on is that it’s not receiving any power. To determine if this is the cause, check the fuse or circuit breakers and see if any have tripped. If it seems to be an electrical issue, call a professional immediately. Working with an electrical system is unsafe, so do not attempt this independently.
The unit blows warm air
If the air conditioner blows warm air, the filters are likely dirty and clogged. The system may be producing cold air but unable to distribute it properly. Replace or clean the air filters at least once a month during the cooling season. If the filters have been changed, ensure the outdoor unit is on and running. If it is on and is not running, call our professionals to have the system inspected.
Frozen air conditioning unit
When a home’s air conditioner freezes, it could be due to various problems. One possibility is a lack of proper airflow. Check if the air filters need to be cleaned or replaced as necessary. Also, ensure the coils are free of dirt, debris, or other obstructions. While a homeowner can clear away debris and change air filters, a certified technician must replace any electrical components.
Watch for these common air conditioning problems to identify and resolve them swiftly. Be sure to contact an HVAC technician with any doubts, as these professionals have the knowledge and skills to restore an air conditioner to working order quickly.
