Top Reasons Your Air Conditioner May Need To Be Fixed
Are you worried about your air conditioner? During the previous summer, did it seem to struggle more than usual with cooling your home? Now is a good time to get your air conditioning unit checked out before spring and summer roll around again. Here are some common issues that you should have checked out:
Refrigerant levels: An air conditioning unit in good condition should have steady levels of coolant. But as your air conditioner ages, it may develop small leaks and start to loose its refrigerant. Because the leaks can start out very small, it may take an entire season for you to notice a drop in cooling efficiency. A good repair technician will be able to pinpoint even small leaks, fixing them so that your unit is fully functional once again.
Interior and exterior fans: A lot of air conditioning units have both internal and external fans. The internal fan will draw air out of your home and through the air conditioner, causing it to be cooled. An external fan will blow air across the air conditioner's coils, transferring heat to the outside air. Either or both of these fans can start to slow down as their motors begin to burn out. If the motors aren't replaced, other parts of your unit can become damaged as they become too hot or too cold.
Mold growth: If you live in an area that's humid, your air conditioning unit's cold coils can attract quite a bit of moisture. This moisture, in turn, can facilitate the growth of mold and mildew. While this mold and mildew can make you sick, it also has the effect of reducing the efficiency of your air conditioner. Some air conditioner units come with internal UV lamps to help combat mold growth while others would have to have these lamps installed separately. If mold has already started to form, it should be cleaned off before anything else is done. After the mold is removed, your repair technician can then either replace the UV bulbs or install new fixtures inside your unit.
Thermostat: Your thermostat could be much older than your air conditioning unit. If the thermostat was working fine when the previous owners replaced the unit, they may not have seen any reason to spend additional money on updating the thermostat. However, the thermostat's temperature sensor could now be faulty and not signaling your air conditioner that it's time to turn on. You could also have a thermostat that sends its signal to the air conditioner wirelessly. It may be a battery operated thermostat, not connected to any wires. Gently pull on the thermostat to see if the cover easily pulls off or swings open. If it does, replace any batteries you find. If it doesn't, you may need to have your repair technician (such as one from Always Ready Repair) replace the thermostat with a new model.
