Common A/C Problems and How to Handle Them
Posted By: 
Tuesday, May 30, 2017

All home appliances eventually face mechanical problems.  Over time as machines get used they will inevitably deteriorate and/or malfunction. Knowing how to recognize, diagnose and mitigate issues quickly will help you to keep your unit running well for longer, as well as saving you money on a/c repairs and replacement.  The following are some of the most common HVAC problems and some simple solutions you can try yourself before calling in the experts.

The air conditioner runs but doesn’t cool. There are any number of possible reasons for this kind of failure but the most common are dirty/clogged condensers and evaporators or low or leaking refrigerant levels.

               Fix: The condenser is where the air is cooled before it’s released into the house and it can easily become blocked or clogged with outside particles or debris. Check that first and if it is dirty or blocked try and clean it out. If that doesn’t fix the problem, then your unit is probably low on or leaking refrigerant.  Because a/c coolant can be highly toxic you should never try to add refrigerant yourself.  Call a professional to check for leaks and do any refills.

The air conditioning unit won’t turn on/repeatedly shuts on and off -- If the issue is the former then the most common reasons are a malfunctioning thermostat, a tripped circuit breakers or clogged vents.  This last one can also cause intermittent shut off and start up, as can a dirty condenser or evaporator.

Fix: First check the circuit breakers near your unit.  If any are is tripped, do a reset and then try to turn the unit back on.  If it is still not working check your thermostat to see if the sensor that measures the temperature has been bumped out of position. It should be near (but not touching) the evaporative coil.  Gently try to move it back into place.  If that doesn’t do it, you can try to clean out the vents but it may be necessary to call an HVAC technician for maintenance or replacement of faulty parts.

The air conditioner is blowing cool air, but the house is still hot. If one room/area of your home is consistently hotter or colder that the rest of the house it usually signals that the air distribution of your a/c unit is out of balance.  This can be due to a dirty evaporator, an undersized unit or too large of a range between your thermostat setting and the outside temperature.

Fix: Make sure all windows and doors are closed and if you have a lot of windows letting in sunlight try putting down the shades on all the windows. When it’s 95 degrees outside any heat gain can counteract whatever cooling you are getting from your unit.  Reduce the thermostat by 5 degrees and see if the room gets any cooler.  If not, clean out the evaporator and let the unit run for a couple hours. If the problem still isn’t resolved, then it is very possible that your A/C unit is not the proper size for your house.  You will need to call an HVAC tech for a professional inspection and opinion.

Even armed with the knowledge of the problems that can arise there are still many issues that you need an expert to resolve.  When you are looking for an a/c contractor nearby, know that at Crane Heating and Cooling we are proud to serve the home comfort needs of our neighbors in and around the Greater Cincinnati area.  For installation, repair and troubleshooting of your HVAC system or to schedule annual maintenance visits with one of our professionals, give us a call at 513-641-4700 or contact us online at info@craneheatingandair.com
