If you’re struggling to keep your AC unit operating properly, there are a few tips that can help you solve your problem. These tips cover everything from checking the refrigerant levels to cleaning the condenser and drain lines.
Troubleshooting a thermostat problem
If the thermostat is not calibrated properly, it may be causing short cycling or other problems that are draining energy efficiency. To adjust this setting, slide the calibration arm toward the “longer” side. Then, adjust the anticipator’s setting to “longer” and let the system run for at least two hours to see the difference.
If you’re wondering how to troubleshoot a thermostat, check your main breaker box and the air conditioning unit. If your thermostat resets to factory defaults after switching circuit breakers or losing power, it’s likely that the unit is malfunctioning. Ideally, it should be programmed to a temperature that you prefer.
Thermostats are the brains of your HVAC system, so they control the temperature of your home. A malfunctioning thermostat can impact comfort and energy cost. As such, it is important to troubleshoot this component regularly.

Checking refrigerant levels
When fixing air conditioning problems, one of the most important tasks is checking the refrigerant levels. Incorrect refrigerant charge can lead to a wide range of problems. Inadequate cooling can be caused by incorrect charge, improper installation, and leaks.
While it is less common than undercharging, overcharging can damage the compressor and cause the system to shut down unexpectedly. Overcharging also makes the air feel more humid and increases the likelihood of a major breakdown or explosion.
Low refrigerant levels can cause the compressor to work overtime to recover from a warm air day. According to https://inspectapedia.com/aircond/AC_Refrigerant_Line_Frost.php, this can lead to ice buildup on the evaporator coil. Moreover, you may notice a water puddle near the furnace, indicating low refrigerant levels which can be changed quickly.

Checking condenser fins
When you’re fixing air conditioning, you should always check the condenser fins. These thin metal slats move warm air from your home away from the AC. This process is critical for your AC to function efficiently. Check the condenser fins before you start fixing your AC.
When your condenser coils are bent, they may not get the air they need. Debris that collects near the coils will interfere with airflow, which will decrease the effectiveness of your cooling system. Grass clippings, fallen leaves, and pet hair can cause the fins to bend. They also can restrict airflow around the condenser.
To clean the condenser, remove the protective grille. Use a soft brush to scrub the fins. Make sure not to use water, as this can turn the dirt into mud and compact it between the fins. Additionally, don’t use a fin comb to clean the fins.
Checking drain lines
One of the easiest ways to fix your air conditioner is to check the drain lines. These lines carry small amounts of water produced by the air conditioner. Don’t worry if you’re looking for air conditioning repair Surprise AZ has several companies that can fix the problem or simply just remove the debris from the drain line. Over time, they can become clogged with debris and cause problems.
To test the drain line, locate the drain pan under the indoor unit. It is usually located on the bottom of the unit. Check it carefully for debris. If it is clogged, a leak in the drain pan could be a sign of a clogged drain line. If the leak is confined to the drain pan, use epoxy glue to plug it.
Once you have located the leak, check the drain lines. Look for a dark mass in the drain pan. If the mass is not there, you should call a plumber to fix the air conditioning system. If the drain is not clogged, you can try flushing the drain line with a solution of vinegar and warm water.
Checking fan belts
When fixing your air conditioning system, it’s important to pay attention to fan belts. It’s important to keep these belts free from kinks, and ensure that they’re functioning properly. Checking fan belts is simple; just turn off your air conditioner and insert a screwdriver into one of the slits on the condenser unit.
If you hear a chirping or whistling noise, it may be time to replace the fan belt. These belts usually make the sounds of a serpentine belt, and can be a good indicator that the fan isn’t working properly. A serpentine belt can wear down and crack if the resistance is too low, so make sure to get a new one.
Another sign that it’s time for a replacement AC belt is the belt snapping. It’s important to replace this belt if it’s broken because old belts are weakened from service and age. Visual inspection is also important to determine whether the belt is broken. A broken belt should be replaced as soon as possible.
Checking capacitors
If your air conditioner suddenly shuts off and the fans don’t spin, chances are that one of the capacitors is bad. To determine which capacitor is bad, you can perform a simple test. If you’re not familiar with high voltages, you should not try to perform this test.
If your AC system has three terminals and a cylindrical canister shape, then it has a run capacitor. These terminals are connected to colored wires coming from the AC unit. When the capacitor is bad, it won’t deliver stored energy to the motor and compressor, resulting in a malfunctioning air conditioning system.
If you see a smoky smell coming from your AC, it’s probably a faulty capacitor. If you’re unsure whether it’s the capacitor or a faulty part, you should take your AC to a professional for a test. They can repair the part or replace the entire unit. A good air conditioning contractor will also be able to measure the voltage and resistance of the capacitor with a millimeter.
