More often than not, shoddy thermostats are responsible for faulty air conditioners. If your thermostat isn’t properly calibrated, it’ll throw off the temperature of your control system. If you’ve detected a defective thermostat, replacing it will remedy the problem. If you’ve held on to the manual, consider consulting it for guidance.


If your ducts are on the fritz, your heating, air conditioning, and refrigeration will soon suffer a tragic demise. When AC units go kaput, leaking ducts are typically the culprit. These passageways transfer cool air from one space to the next. With that said, when they aren’t up to snuff, it disrupts the airflow. Moreover, your air conditioner is forced to work harder and, as a result, your energy bill spikes.

Refrigerant Lines

Perhaps the word that gets tossed around the most in the AC domain is refrigerant. In short, refrigerant helps eliminate heat and humidity. When refrigerant levels are low, heat and humidity run rampant. If your AC system is exhibiting signs of decay, refrigerant lines are generally the first to experience adverse effects. Some of which include leaks and corrosion. Any noticeable holes should be repaired immediately. If your refrigerant lines are intact, you may need to replace the refrigerant itself.


Clogged drains don’t bode well for any apparatus. This sentiment rings undoubtedly true for air conditioners. The moisture that your air conditioner collects is removed via the drain line. If this pathway is blocked, the moisture will build up. The result is usually a stuffy, muggy, and overall unpleasant atmosphere. If this problem goes unchecked for too long, it can cause irreparable water damage. If you’re concerned about the condition that your drain is in, hire a trained technician.

Air conditioning issues are invariably stressful. Fortunately, when complications occur, it doesn’t mean you have to bid your AC unit farewell. Above are some areas you’ll want to look into to see if your system is worth salvaging. If you’re unsure of how to proceed, an HVAC specialist, such as Master Service Heating, Air Conditioning & Refrigeration, can assist.
