Common Air Conditioning Problems

Your guide to central A/C maintenance and repairs.

central air problems Chester County, MD When the summer swelter rolls into Central Delmarva, nothing beats the welcome chill of air conditioining — unless, of course, your home’s central A/C throws a tantrum and starts acting up.

Homeowners in Chester County turn to the team at Poore’s Propane and Oil to ensure that their air conditioning woes don’t last long. Here are some answers to some of the A/C questions our team regularly hears.

Why Is My A/C Leaking Fluid?

We know it’s disconcerting to see a puddle of liquid around your A/C equipment, but it probably isn’t cause for panic. More often than not, it’s just condensation, which accumulates in any healthy cooling system. This condensation typically drains from the condensate drain line. To prevent it from leaking elsewhere, regularly clean the A/C unit to ensure proper drainage and arrange regular maintenance to keep this line from getting clogged.

If the liquid coming from your A/C is dark, it could be refrigerant, which is a health hazard and should be handled by a professional.

Why Won’t My A/C Turn On?

A non-responsive A/C unit can stem from various issues. Many of them are easily fixable without an HVAC technician’s visit. Begin troubleshooting with these steps:

  1. Check that your thermostat is set to “air conditioning,” “cool” or “fan,” and also set the thermostat below the current room temperature.
  2. Make sure the A/C’s power switch is on.
  3. Inspect the circuit breakers and fuses to see if a switch has flipped or a fuse has blown.

If none of these steps work, it’s time to call in a professional.

Why Is My A/C Blowing Warm Air?

If you’re getting warm air from your vents and air handlers when you should get cold air, it’s often due to poor airflow or a compressor issue. The first thing to do is check your air filters. (You should do this once a month during the peak heating and cooling season.) Replace any dirty filters, which can obstruct airflow. If that doesn’t work, inspect the outside A/C unit for any debris or blockages.

Other potential causes for warm air could be low refrigerant levels or compressor malfunctions. A Poore’s technician can look at your cooling equipment and diagnose the problem.

Why Is My A/C Making Strange Noises?

Clanging, banging, squealing and grinding are all abnormal sounds to hear from your A/C. If you’re hearing them regularly from your equipment, it’s an issue demanding your attention.

Strange noises can result from a loose part, a failing motor bearing, a slipping belt or a wiring problem. Turn off the unit immediately if you suspect this is the case to prevent further damage.
