Here’s our deeply experienced look at the ten most common problems with older air conditioning systems and how to best prepare for them. If you will be here in Waterloo, Guelph, Cambridge, Kitchener and South Ontario surrounding areas this summer pay attention. You could really be glad you did!

  1. Age. It may seem obvious, but if your air conditioning unit is an older one, it will likely have experienced considerable wear and tear. This could make the unit not work as well as it should, and leave your home not as cool as it should be. Or be the cause of many other issues. The good news is bringing a professional in for air conditioning maintenance can remove these headaches before they happen.
  2. Fans or Belts Not Performing. Small inefficiencies from age can often make internal fans or belts become worn and not run optimally. The results in your air conditioning unit working poorly, or even making weird noises. Having this taken care of before something breaks is a very good idea.
  3. Icing Up. If your air conditioning unit has ice formed on its outside, it is likely either a filter that needs to be changed, or it could point to a larger problem like a broken fan, a refrigerant leak, or a condenser that is no longer working.
  4. Leaking Refrigerant. Many people make the mistake of thinking if the refrigerant in their A.C. unit is low, just adding more will solve the problem. Chances are it won’t. You probably have a leak that will need to be repaired.
  5. Electrical Problems. As your A.C. unit ages the chances of electrical shorts skyrockets. Failing capacitors, damaged relays, and tripped circuit breakers are some of the possibilities. These can actually lead to a fire, which makes regular maintenance a must.
  6. Fan Issues. Your A.C. unit has two fans that are necessary for it to operate properly. One blows air from inside the home over its coils and brings the temperature of the air down. The other pushes the hot air outside of the home. If either fails and the unit continues to run, its compressor could fail. And that is so expensive to replace, you may as well by a new unit.
  7. Leaking Water. It’s a good idea to make sure the A.C. unit’s drains are clear and its overflow pan is attached and working. Otherwise water leaking internally could damage the air conditioning unit, and if the leak is external it could cause damage to your home.
  8. Poor Air Quality. It’s recommended that you have your air conditioning unit’s air ducts cleaned every few years. If not you could end up facing mold and mildew which can actually cause health problems. Dust, debris, and even things like pet fur accumulate in its air ducts.
  9. Misaligned Sensor. If your air conditioning unit’s thermostat isn’t functioning correctly, you could end up with having the nightmare of the unit turning on and off at seemingly random times. Replacing it can be a quick and easy fix.

The best way to get ready for the hot South Ontario summer when it comes to your air conditioning unit is a simple call. Bring in a professional to do normal A.C. maintenance and take a look and see if there’s anything else that needs to be repaired. Having it done on your schedule, is much better than having to bring in someone to fix the unit in an emergency. No one wants to be A.C. free this summer, even if it’s only for a day or two.
