Cooling your house in the summer is one of the most important things you, as a homeowner, can do. Your AC unit gives you relief from the summer heat and allows you to be more productive during even the hottest days.
However, at some point, almost every AC unit starts to blow warm air. This can be incredibly uncomfortable, not to mention a waste of your hard-earned money.
So what is causing your AC blowing warm air and how can you fix the problem? Keep reading to find out.
Inadequate Refrigerant Levels
This can be caused by anything from a refrigerant leak, or an incorrect charge during the initial installation. Solutions to this problem include having an HVAC technician repair any potential leaks, as well as recharging the AC system with the correct amount of refrigerant.
The technician will use a special tool that can accurately measure the amount of refrigerant and verify that it is at the recommended levels for proper operation. Additionally, if the leak is not repairable, the technician may recommend that the system be replaced.
Clogged Filters
The filters can be blocked with dust and debris, blocking their ability to absorb cold air, so when warm air is pushed through the system, the warm air is all that comes out. To solve this issue, the filters need to be cleaned and replaced regularly to ensure that they can filter the air adequately.
It’s recommended to change the filters every 6-12 months and to clean them regularly – either by vacuuming or wiping them down and checking for debris. Following this procedure can help reduce the chances of clogged filters and help ensure that the air conditioner will be blowing cold air.
Faulty Relays
One of the many signs you need HVAC repair is if warm air is being emitted from the air conditioner instead of cool air. This can be caused by faulty relays, which are part of the air conditioner’s compressor. If the relay is damaged, it can cause the compressor to shut down and leave the air conditioning system unable to give cold air.
To resolve the issue, the faulty relay must be removed and replaced with a new one. Repairing or replacing a defective relay will help ensure that cold air from the air conditioner is once again flowing through your home.
Faulty Capacitors
The capacitor is a device specifically designed to store electricity and smooth out the electrical current flow. If these capacitors become defective, the blower motor can’t achieve the desired speed and the compressor will not kick on, resulting in warm air still being blown out.
The first step to solving this issue is assessing which capacitor is the cause. This usually involves probing the capacitors with a multimeter. If these solutions don’t work, you may need to call a service technician to further diagnose the issue.
