Air conditioners are complicated. Some homeowners try to repair them on their own in order to avoid the expense of professional service. However, more often than not, serious repairs simply require the skills of an experienced technician.  In spite of this, you can perform a few simple maintenance steps on your own.

The most useful tip we can offer you is this: change your air filter regularly. If the filter is dirty or clogged, the system cannot work efficiently. Furthermore, a clogged filter could lead to your whole unit freezing. Filters need to be checked, cleaned, and replaced on a near-monthly basis. We also highly recommend executing a thorough cleaning. Don’t stop with the air filter -- you should clean the entire unit. On the outside, clean the fan blades and remove any accumulated debris. You can also clean the condenser fins.

In this way, you can avoid as many expensive repairs as possible and keep your air conditioner running efficiently for years to come.

Signs You Need a Repair

Watch out for these signs that it's time for air conditioning repair.

  • Uneven cooling
  • The unit turns off and on quickly and constantly
  • House not cooling well
  • The condenser isn't running
  • The unit is overheating

If you detect any of these symptoms before a break down, contact our McQuerry's service technicians before you lose your indoor cooling completely. Remember, the best way to prevent break downs and major expensive repairs is to have a regular air conditioning maintenance schedule.

How Do I Know if My A.C. is Working Properly?

During the heat of summer, everyone loves to hear the steady hum of an air conditioner in the background. On particularly sweltering days, though, it can be hard to tell if your air conditioner is actually functioning. In most cases, the system is working exactly as it should -- it just has a lot to work against. However, you can always check for yourself.

First, test the air temperature differential. If it’s 80 degrees outside, set your thermostat below that. Let your unit run long enough to reach the new temperature. Then, place a thermometer inside an air duct. After 10 minutes, check the temperature readings. You’ll immediately know whether the system is working properly or not. You can also check the air filter. A dirty filter means the unit isn’t functioning properly. Change it monthly to avoid problems. If your air conditioner refuses to work, it might need further cleaning in the ductwork or outdoor unit.

Why Do I Need to Change My Filter Regularly?

Every air conditioning technician will tell you to change out your air filter on a monthly basis. Over time, the filter will accumulate dirt and debris, resulting in decreased efficiency and airflow. The unit will not be able to keep up with the heat. Furthermore, a dirty filter allows all manner of dust, allergens, and contaminants into your home. What air does leak through will carry particles, decreasing the quality of your indoor air. Reduced indoor air quality is a leading factor in numerous health issues, including asthma, lung irritation, and respiratory diseases. In rare cases, it can even lead to cancer. You can avoid all this trouble by simply changing your air filter each month. This will also increase your energy efficiency, lower your monthly bills, and allow you to enjoy a more refreshing environment. It’s a simple task that can make a big difference.
