Sure Signs That Your Air Conditioner Needs Repair
Nothing is worse than a broken AC unit the middle of summer! There can be many causes behind an air conditioner not functioning properly, so before you try to fix it or call a heating & cooling professional to come work on it, check a few things first, so you can get a clearer idea of what the source of the problem is.
Here are a few common types of air conditioning malfunctions and what the potential causes may be:
- The air is not cool enough. Check to see if the Freon lines are frosted up. Poor airflow is often caused by the cooling coil fronting up, which makes it unable cool the warm air passing through it. This is usually caused either by blocked vents and dirt or the thermostat being set too low, which causes the coils to freeze. The solution to this problem is to turn off the air conditioner and leave it for a few hours with just the fan running to melt the frost off the ice. Another reason behind air not being cool enough is a leak in the system, resulting in low refrigerant. The leaks must be repaired before you can add more Freon to the system. You can purchase convenient leak stop kits for emergency leaks, which will allow you to fix the problem easily.
- There is no cooling at all. If the outdoor fan unit is still running, but only warm air is coming out of the vents, this can be due to a variety of problems. Usually, it is due to a damaged compressor. Outdoor condensing units are equipped with a fan and a compressor, but the fan can work even if the compressor does not. It can be difficult to determine if this has occurred, but it is not uncommon. It is best to hire a professional work on the issue, as there are many electrical components involved that require certain skills to address.
- There are loud noises. Check to see if the loud noises are coming from the indoor unit or the outdoor unit. There are three components in the outdoor unit that can cause noise, including the fan motor, which causes screeches, the compressor, which is louder and more like a hammer or a growl, and the contactor, which buzzes or hums.
