Your home AC is one of those things you will probably miss the most if it malfunctions, especially on a hot and humid spring or summer day. After the winter weather where you perhaps didn't turn on the AC regularly, you need to ensure that an HVAC contractor comes in to maintain the cooling system so it works well when temperatures rise in the coming weeks.
Simply having your air filters cleaned, air ducts checked for leaks and the refrigerant level on your condenser checked can enhance the efficiency of the AC and keep your home cool and comfy in the coming months. Here are simple tips for troubleshooting common problems with your air conditioning so as to keep it running smoothly.
AC won't dehumidify adequately
If your AC won't adequately suck up moisture in your home, it is likely too large for your indoor space. To fix this, you can talk to your HVAC contractor about expanding ductwork into your garage and attic so as to increase the load on the system. Alternatively, have your current AC replaced with one that is adequately sized for your home.
If you still have excess moisture after replacing your AC or increasing the load on your current one, the problem could be excessive moisture entering the home through gaps in your windows or walls. You can remedy this by closing any gaps in your home that could be letting in moist air and boosting your condensing unit's dehumidifying power with a portable dehumidifier, especially in the basement and attic where moisture could build up.
AC won't cycle properly
A condensing unit that runs a long on cycle without effectively cooling your home is probably worn out or running low on refrigerant. An HVAC contractor can fix this by adding more Freon to the unit or replacing worn out condenser fans or motors.
Similarly, if your AC unit runs a very short on cycle, it won't be able to offer effective cooling. The issue could be caused by obstructed air flow in the condenser that makes the condensing unit to overheat prematurely. This can be fixed by straightening bent condenser fins with a fin comb or removing twigs and branches that could be obstructing the free movement of condenser fins so as to improve the supply of air to the AC.
If that doesn't fix the short cycling issue, replace dirty or clogged air filters and have your unit inspected for refrigerant leaks that could be affecting the AC unit's ability to transfer heat to the outdoors.
