Most people consider holidays as an off-season for the AC system. So, make it an excellent opportunity to have it checked for any problems it could have developed in the hot season and autumn because of constant operation. Moreover, having a maintenance check in the off-season costs less, and you will not have to wait longer periods as you would during the peak season. Here are three common issues the HVAC service expert will likely catch and how to fix them.
The System Doesn't Blow Cold Air
An air conditioner that doesn't blow cold air into the home can frustrate you. Note that the system needs a recommended refrigerant volume to efficiently cool air in your home. However, if there is a leak in the system, the cooling will not happen. As such, the air will cycle back into the room at the same temperature it went into the unit. To rectify this, the AC repair expert will check for leaks in the system, seal them, and regas your unit for proper cooling.
The AC Runs Constantly
Typically, the air conditioning unit runs for a particular time before it switches off. Also, most units are automated, so when temperatures inside the room rise above the reading on the thermostat, the AC will kick in and start cooling. However, many things can interfere with this automatic function. For example, if the thermostat is not working as it should, the system may not sense that the ideal temperature has been reached and then turn off. Instead, it will keep running. Also, if you have less than enough refrigerant in the system, it will not remove heat as fast as it should. Consequently, the system will keep running longer than it should. In such cases, an HVAC service technician will assess the refrigerant and your thermostat for possible issues and rectify them to restore proper unit cycles.
The Unit Stays Frozen
Freezing is another indicator that your air conditioner is not working as it should. You should know when the coolant levels are low, the heat exchange process doesn't happen as it should. Therefore, if yours keeps freezing, you have low refrigerant levels, or the filters are clogged with dirt. If this is the case, the low coolant level will lead to the condensation of the evaporator coils. Also, the same happens when the filters are dirty and cannot allow enough air into the system for the cooling process. So, you can try changing or cleaning the filters to see if the freezing will stop. However, you should call the air conditioning expert to resolve problems affecting the refrigerant.
