Cooling System Troubleshooting - Save Money and Stay Cool with These Simple Tips

cooling system troubleshooting tipsP.K. Wadsworth Heating and Cooling has been servicing just about every kind of air conditioning system for the better part of a century—spanning four generations of the Wadsworth family. Our goal is to have happy customers, and sometimes that means providing tips that will help them diagnose and solve problems themselves.

Here are some basic items to check before turning to a professional to repair your air conditioning system:

  • Make sure the thermostat is set correctly.
    Both the temperature and heat/cool/off system setting will determine if a system kicks on. Remember to give your air conditioning system a few minutes to react to the proper setting. There may be built-in delays to protect the equipment from cycling too rapidly.
  • Be sure the time on thermostat is accurate.
    An inaccurate thermostat time is most likely the result of a time change or power outage. Check your thermostat like any other clock in your home and make sure it’s set to the correct time.
  • Check and change thermostat batteries regularly.
    Many thermostats (though not all) require batteries and low batteries can affect performance, so it’s best to change them every six to 12 months. If you’re unsure how, ask a professional to show you during your next regular service appointment. When the batteries are near replacement, check for a battery icon in the display.
  • Close all your windows.
    Summer in Greater Cleveland can be hot, and sometimes unwanted heat comes from a forgotten open window. This often happens when the weather is transitional and windows get opened to air out the house.
  • Make sure your system’s breathing well.
    If you notice less airflow, make sure your air ducts are sealed and cleaned. Check to make sure the system filter is clear and not clogged with dirt.
  • Check your fuse box.
    Sometimes a reset breaker is all you need to get up and running. If a breaker goes out repeatedly, be sure to call us to make sure your system is running correctly. Repeatedly tripping a breaker also will weaken it. This should be avoided by addressing the root cause. Weak breakers always must be replaced.
  • Check the outdoor temperature.
    Extreme temperatures can leave even the best systems struggling to keep up. For example, most air conditioners can reduce the temperature only about 20 degrees compared to outdoor temperatures.
  • Turn off your programmable thermostat during record-setting weather.
    During extreme weather, it’s too difficult to recover from the setback temperature setting on a programmable thermostat. It’s just too hard to make up the difference. Turn off the setback until normal temperature patterns return.
  • Take the cover off your AC unit at the beginning of the season.
    If you use a cover, be absolutely sure you don’t run the AC with the cover on. In a very short period of time you can do a lot of damage and even destroy the major components of your system. Also make sure the cover is the correct cover for your system and doesn’t trap in moisture. Trapped moisture can cause greater problems than leaving the unit uncovered.

AC Tips


 

"Fantastic from start to finish. I just had a great experience with the guys over at P.K. Wadsworth Heating & Cooling. The salesman who helped me out when I went in was absolutely fantastic. He really took the time to listen to what I really wanted and gave me suggestions based on what I told him. I really like that he didn’t try to upsell me with things I didn’t need. Once I made my decision, they were really quick to schedule an appointment to install my new unit. The technician who they sent out was really great as well and did the whole install in such a quick and efficient manner. My unit is working like a dream and I could not be happier. If I need any service or a new unit in the future I will definitely be coming back to these guys."
