Air conditioners regulate the temperature indoors during hot days, keep out pollutants and contaminants, and maintain comfortable humidity levels in the home. Despite the amount of use AC units get, many homeowners wait until small issues become large problems to schedule an air conditioning repair service. Here are a few common reasons for repair calls.Lack of MaintenanceWhen it comes to keeping an HVAC unit in good working condition, regular maintenance is key. A routine tune-up can help keep units working all summer long. When homeowners neglect regular maintenance, small issues can become costly headaches. Remember, technicians can spot damage before it causes a major issue.Moisture Inside the SystemAir conditioning units are designed to reduce the risk of moisture building up in the system. A central drain line funnels excess moisture outside, where it can do no damage to the home. However, if the drain line gets clogged, water can pool inside the system, leading to corrosion, mold, and even electrical issues. Furthermore, the moisture build-up can attract pests that can damage other parts of the home. These repairs require an experienced professional and should not be handled by the homeowner.Overused and Overworked AC UnitsDuring the hottest days of the summer, many homeowners run their systems continuously. While this does keep homes cooler, it can also damage the air conditioning unit. The constant use places a lot of strain on the system and can cause severe damage when the unit is not properly maintained. An overused unit may even stop working, resulting in an expensive air conditioning repair that could likely have been avoided with a routine maintenance appointment.Improperly Sized AC UnitsWhen a technician installs a unit, they always look at the size of the home to determine which unit will work best. If a unit is too small to cool a home properly, the air conditioner may break, forcing the homeowner to call an air conditioning repair technician to assess the problem. It’s important to note that unless the unit is upgraded or supported by additional units, an undersized AC will likely break again after repairs.Faulty WiringWhen an unlicensed contractor or handyman installs an AC unit, they may not be familiar with the proper safety protocols for installation and could wire the unit incorrectly. If this is the case, the air conditioner won’t work as efficiently and may even be a fire hazard. Homeowners who notice that their unit runs without cooling the room or constantly trips the circuit breaker should schedule a consultation immediately.Avoid these common repair problems by scheduling routine maintenance each year. Call a local AC repair expert to be prepared for summer before it arrives.
