Why Isn't the AC Turning On or Cooling? Common Causes and Solutions

As the warm weather floods the area, many of us are turning our heat down to cool. Unfortunately, you might find that things aren’t cooling off as you had hoped. When the heat rushes in, it does so quickly, meaning that it is go-time for your air conditioner! If you are having a hard time cooling things down, try these troubleshooting tips from our residential HVAC Charleston pros!

Thar She Won’t Blow…

If you turn on your air conditioning and the cold air won’t blow, first check to make sure that the registers are open and not blocked. Second, check your thermostat to ensure that the batteries are working. After doing both of those, try changing the air filter. During the spring, pollen can wreak havoc on your HVAC system and clog the air filters to the point they stop the flow of air to and from the unit. If your air conditioning unit’s filter is clogged, then it can lead to freezing the evaporator coil, which can result in burning your unit out. If all else fails, there might be a problem with the fan or the motor, which will require that you call our residential HVAC Charleston company.

It isn’t Cold Enough

If you are having a hard time maintaining cold areas in your home, the first likely suspect is going to be your vent registers. If you have just one shut off, it can make a dramatic difference. The next culprit could be that your refrigerant line leaks. Other issues might be that the size of your unit isn’t appropriately proportioned to the square footage of your home, in which case you might want to consider upgrading. When your system has to run constantly, over time, it will eventually lead to a breakdown. And if that happens, not only will you have to call an emergency repair company; you’ll have to replace the entire unit. Prevention is always better than replacement!

Air Conditioner is Leaking Water Inside

For homeowners who have not checked their air conditioner, the water pan can sometimes runneth over, which will lead to flooding and water damage. Also, the drain line can become clogged, and it will back up into your air conditioning unit. First, try to vacuum out the line. If that doesn’t work, then it could be that the line is rusted or your condenser pump is broken. Either way, it will probably require that you hire an HVAC company.

Air Conditioner Leaking Water Outside

During super-hot days, it is not uncommon to see water pooling around your condenser unit. When it is cold outside, however, water should not be there. If you notice the unit leaking at any other time, then it is probably a refrigerant leak that needs to be repaired. It could be that you have a block in your drain pipe or the condensate pan is no longer connected.

Your Air Conditioning Runs Incessantly

Sometimes the hot and humid conditions can make your unit work overtime. If it never shuts off, however, that is not a good sign. Try turning off the unit and either clean or replace the filter and see if that solves the problem. If you have recently added square footage, it could be that your air conditioner simply can’t keep up with the demands placed on it. If that is the case, it is a good idea to call an HVAC company to see if an upgrade is warranted.

As the warmer weather makes its way here, now is the perfect time to test out your air conditioning system to make sure that it is good to go on the first day of summer. As anyone in the area can confirm, summer will insist that your HVAC be ready on day one!
