When it is hot outside, the last thing you want to do is to come home to a warm house. For many homeowners, this is bound to happen at one point in time. There are many reasons why your air conditioning system may quit working all of a sudden. It can be as something simple as needing Freon or as big as needing a complete replacement. Whatever the problem is, it is a good idea to troubleshoot the problem before calling your local HVAC technician. This allows you to save time and money with a quicker diagnosis from your HVAC repairman. Here are some common air conditioning repair problems you can expect.
Unit Freezes Up
One of the most common problems homeowners face with their air conditioning system is it freezing up. This happens when the coils freeze over. It can be caused by numerous problems including dirty air filters or low refrigerant. In order to see if the unit has frozen up, you need to check the vents to see if air is blowing. If the air is blowing, but it is not cold, this is usually a common sign that the unit is frozen. The technician should be notified so they can go straight to work figuring out what caused the coils to freeze.
Your thermostat could be the reason your air conditioning system is not working properly. Many times, it could be as simple as needing new batteries. It could also be that the thermostat needs to be calibrated. In order to figure out if the thermostat is bad, you will want to set it about 5 degrees lower than you normally would. This should trigger the A/C unit to turn on. If that does not happen, you will want to go turn the breaker off to the unit. Take the cover off the thermostat and make sure the wires are attached. Turn the breaker back on and check to see if the unit is using.
At times, your unit may run more in order to keep it at the temperature you set it at. When you notice it needing to put out more energy, this is often a sign that it is not running as efficiently as it once did. This can cause your energy bill to increase. An inefficiency in your air conditioning system is a sign that your unit has not been maintained properly. The best way to avoid this is through preventative maintenance checks on the system.
