The heating and cooling unit in a home is something most homeowners really do not pay attention to unless it is broken. Once it is not working properly, panic sets in and it can be hard to think rationally about the problem. However, before you call a technician for heating and air repair in Loganville, you can save yourself a little bit of frustration by running your own, simple diagnosis of the unit to narrow down where the problem is located. Check the Thermostat This is the first place homeowners should start their diagnosis. The thermostat is the life force of both the air conditioner and the furnace. It will read the current temperature and relay a message to the unit telling it when to turn off and on. If it is not turned on or the wrong setting is selected, there is no message to be sent. If the temperature setting is too unrealistic, the system will work continuously without reaching a comfortable level. This can put a strain on the system and cause problems. Adjusting your thermostat may fix the problem without calling for service. Wiring Issues If the wiring is faulty, your thermostat still may not work because the message cannot get to the HVAC unit. There may be corroded connections at the unit that are producing intermittent connections. The thermostat may also have been installed incorrectly and the wires were not tightened all the way. This can lead to a missing connection altogether. Each half of the unit also has several wires that can experience connection problems. If you find corroded wiring, you'll need to call an HVAC tech to help you fix this issue. Fan Problems Besides the thermostat, the wiring to and from the fan is another major problem HVAC units face. But, there can be other problems with the fan as well. Because the fan works to circulate the air no matter what the temperature may be, it is the hardest working component in the HVAC unit. The motor that turns the fan could be overworked and burning out. If the air filter is not changed regularly, the fan has to work harder to keep the air moving. It also will begin to collect the dust and dirt eventually causing the fan to stop spinning. While you may not be able to fix a fan issue yourself, you can change the air filter if it is dirty. In some cases, this will give the fan the break it needs and the unit will start working correctly. Coolant and Condensation Issues The air conditioning part of the HVAC unit is usually plagued by one of two reasons. The first is incorrect coolant levels, which prevent the air from being cool enough to reach a comfortable temperature. The coolant is responsible for moving the heat energy out of the house. If the level is too high or too low, the coolant cannot trap enough heat energy and carry it out. The second likely scenario is that the evaporator fan is not drying the condensation that can form in more humid areas. Any condensation will begin to freeze on the coolant tubes and coils, making it difficult for the coolant to reach the air. These problems may be easy to spot by an untrained eye, but not easy to fix. Let an HVAC specialist help you adjust coolant levels and wipe off condensation on tubes and coils. Regular Maintenance Is the Best Prevention So, you've solved the problem either on your own or with the help of an HVAC tech. Now how do you prevent the problem from coming back? The key to avoiding heating and air repair in Loganville is to make sure you properly maintain the unit. Ask your local HVAC company about regular maintenance programs they offer that are inexpensive and highly effective at keeping small problems at bay.
