5 Most Common A/C Problems and How to Avoid Them

5 Most Common A/C Problems and How to Avoid Them

In the hot Florida heat, your air conditioner is working overtime and is bound to run into maintenance issues here and there. However, that doesn’t mean that you shouldn’t be taking care of your HVAC system in order to prevent these problems from happening (or becoming costlier). Keep your A/C low-cost and efficient by watching out for these five common problems.

1. Electric Control Failure

 Over time, the compressor and fan controls in your system begin to wear out and wires and terminals can become corroded. Faulty wiring can be dangerous and a possible fire hazard, which is why it’s so important to have scheduled maintenance checks. If you suspect your unit might be experiencing electrical problems, do not risk electrical shock by trying to fix the problem yourself. Call a trained HVAC professional who can quickly and safely fix the issue for you.

2. Condensate Drainage Issues

When it’s hot and humid outside (as it often is in Florida), your condensate drain will experience more condensation than usual. This condensation build-up can cause mold, blockages, leaking, and flooding. Your unit should be routinely cleaned and checked in order to stop these problems from arising. Make sure that condensate drain system inspection and cleaning is included in your seasonal HVAC maintenance agreement.

3. Sensor Problems

If you’re having A/C problems, a quick and easy check is to make sure that your thermostat sensor hasn’t shifted. Your sensor is located behind the control panel, where it measures the temperature of air coming into the evaporative coil. If knocked out of place, it can cause your unit to behave erratically. Your sensor should be near the coil but not touching it and can be repositioned by carefully bending the wire that holds it in place. If you have no experience with unit maintenance or repair, call a technician to handle this for you.

4. Inadequate Cleaning and Maintenance

Just like anything else, your HVAC unit accumulates dust and dirt. There are lots of factors that contribute to it (pets, air quality, filter type, etc.), so there is no exact science to how often you should change your air filter. For best results, check your filter every month or so and, if it’s dirty, change it. Your air conditioning coils should be cleaned during your scheduled maintenance visit.

5. Refrigerant Leaks

Your unit’s refrigerant charge should match the manufacturer’s specifications exactly, without being under- or overcharged. If you’re low on refrigerant, it is mostly likely a sign of a leak somewhere within the system. Unfortunately, the problem cannot be solved by simply adding more refrigerant. You’ll need to call a technician to locate, repair, and test the leak to ensure it is properly and safely fixed. Only then can the tech recharge the system back to the correct level of coolant.

Most HVAC system issues can be minimized or avoided entirely with regular scheduled maintenance checks. Save yourself money and stress by calling (239) 694-4849 to request a free estimate and get 10% off repairs with D & D Air Conditioning and Heating.
