If your air conditioner isn’t working correctly, check whether the fuse or the circuit breaker has blown or tripped. If the problem persists, it’s time to call in a professional!
A well-functioning air conditioning unit reduces humidity, which can lead to mildew and musty smells in your home. It also saves you a lot on your electricity bill as it won’t be running in overdrive to cool the house.
Thermostat Issues
Thermostats are not designed to last forever and can break down or malfunction. Luckily, the thermostat is usually one of the least expensive parts of an air conditioning system to replace.
The first sign of a thermostat problem is often that the display is dark. This is easy to fix by checking that the power switch is on and ensuring the batteries are fresh.
However, it might be time to call Dallas air conditioning companies if the issue is more severe than a tripped circuit breaker or a dead battery. Thermostats are also subject to dirt and dust, which can cause problems, so cleaning them regularly is necessary.
Electrical Issues
Air conditioners run on complex electrical components that can cause issues if they break down. These issues include corroded wires that keep electricity from flowing through the system and other problems such as short circuits.
Electrical issues can be challenging to diagnose because they often require you to work with high voltages and other hazardous materials. Therefore, always use insulated tools and wear protective gloves when performing electrical repairs on your AC.
Some electrical issues that need repair include burnt wires, melted insulation, damaged circuit boards, or faulty capacitors. If you suspect your aircon has an electrical problem, turn off the power to the unit by flipping the breaker in the main electrical panel. Then, check for 240 voltage by following the two wires that carry electricity to the condenser access panel using a voltage tester.
Water Leakage
If you notice water leaking from your air conditioner, turning it off immediately is essential. You can then check the drip pans if you have them. Under the evaporator coil, the primary drain pan is usually welded in place and can’t be removed, but you may be able to replace a smaller drip pan attached to it.
The problem could also be a clogged condensate drain line, where dirt, dust, or mold has built up over time. You can try clearing this yourself, but getting a professional is best to avoid further damage to the unit and potential flooding in your home.
Faulty Compressor
Located in the outdoor portion of your air conditioning unit, your compressor is one of the most critical components responsible for turning your refrigerant gas into cool air. Hence, if your compressor is faulty, it can cause many problems.
If your compressor starts making chattering or ticking noises, you should get it checked out immediately, as this indicates that it is losing its ability to create. Also, if it keeps tripping your circuit breaker, that is a sign that it’s overheating and drawing too much power, which is a fire hazard. It’s best to call a Natrad technician for help.
Faulty Evaporator Coil
An air conditioner’s evaporator coil is a critical component in your system that holds the refrigerant and draws warmth from the household air. It is essential to your system’s performance and health, so technicians recommend routine maintenance.
A faulty evaporator coil can cause your AC to leak coolant. You may notice this as a warm airflow from your vents. It would help if you also looked for oily residue around the drip pan, which shows that your coil needs cleaning.
Faulty Condensate Pump
A faulty condensate pump will stop your air conditioner from working, so checking that the drain line isn’t blocked is essential. If it is, you can use a full cup of vinegar, peroxide, or bleach to flush the line.
If everything works fine, you should see water from the drain hose within a minute. If it doesn’t, it means there is a blockage somewhere. The pump reservoir is an excellent place to start looking. It is usually a transparent plastic tank. The float switch is there to prevent the tank from overflowing, and it will shut off the AC when the level gets too high.
Faulty Fan
If your car’s air conditioning isn’t as effective as it used to be, the issue could be a faulty radiator fan. The fan is responsible for pulling air across the AC condenser and can be affected by conditions like a clogged vent or dust buildup.
Blown circuit fuses are another sign of a problem with your fans’ motors. The motors might surge or fail, causing them to blow a fuse to protect the rest of your system from damage.
You can check for a blown fuse by testing a 4-pin relay using a multimeter or a fuse tester. Alternatively, you can jump between the black (“hot”) wires and the fan relay to see if it works.
Faulty Thermostat
If your aircon’s thermostat displays a dark screen, it’s time to replace the batteries. Then, check the power supply and reset the system breaker.
Similarly, if your unit blows cool air slower than usual, it might indicate a clogged air filter or frozen evaporator coil. A duct cleaning should help.
You can also remove the thermostat cover and use canned air or a soft artist brush to remove dust from the inside. Ensure the wires are firmly connected to their respective mounting screws, too. Otherwise, you’ll have to call a technician for an inspection.
