Homeowners who work, exercise, or run household errands during hot, humid summer weather may find themselves daydreaming about the cool air that will envelop them when they arrive home and enter their front door. If, however, the home's air conditioning system has developed a problem, that longed-for cooling experience may be less and less enjoyable as the summer heat increases.
If you have just arrived home expecting cool comfort but were disappointed to find an uncomfortably warm room instead, here are some potential air conditioning system issues you may be facing.
If the air conditioning system has suddenly begun to fail after a history of reliability, the problem may be as simple as an incorrectly set thermostat. Before moving on to other potential causes, it can be helpful for homeowners to check their thermostat settings to ensure that it is set correctly and functioning as it should. In addition to being improperly adjusted by the occupants of the home, thermostats can fail to work properly due to calibration issues that can cause them to be inaccurate.
Residential air conditioning systems can also struggle to cool the home adequately if there are existing maintenance issues. The process of cooling an average home requires the central AC components to force air through a system of ducts and vents, some of which are equipped with filters. If these air filters become clogged and are not promptly replaced with fresh ones, the system may become unable to cool the home as well as it should.
Central air conditioning systems are actually made up of several components, each with a specific job to perform. Blower assemblies and duct systems move the air, while compressors and condensers perform the process needed to create the cooling effect. With each component made up of many moving parts, even small mechanical issues can be enough to prevent the system from cooling the home as efficiently as it should.
An aging system
Homeowners can also see a marked decline in the performance of their air conditioning systems when the components near or pass their expected lifespan. The stress of summer heat can be particularly hard on marginal systems, exerting stress that contributes to their demise. Whether your cooling problems were caused by one of the problems mentioned above or advanced age, discussing the situation with an air conditioning contractor will help you determine the root cause of the problem and decide on your best option for addressing it.
