The Essential Guide to Air Conditioning Repair

Wednesday, December 20, 2023


Your air conditioning system works hard to keep your home cool. But it also experiences wear and tear from regular use.

It's essential to find signs that it needs maintenance or repair. Identifying these issues early prevents them from becoming more significant problems that require more extensive repairs.

These DIY tips can help you avoid costly emergency repairs to your AC.

Check the Electrical Connections

Air conditioning repair involves a lot of electrical work and should only be done by qualified technicians. These professionals understand how different electric components interact within an AC system and know how to troubleshoot complex wiring issues.

Performing this type of work without understanding the electrical schematics of an HVAC Linden NJ system could lead to disastrous consequences. These risks include electrocution and high carbon monoxide levels that threaten the health of family members.

Before doing any electrical work on an air conditioner, it's essential to shut off the power to the unit using the main circuit breaker. This is to prevent accidental shocks that could be dangerous or even fatal. Additionally, insulated tools and protective eyewear are essential for conducting any maintenance or testing involving electricity.

Check the Compressor

The compressor is the heart of your air conditioning system. It's the only moving part in the system and draws its power directly from your car engine. It's also the most expensive component in your air conditioning system to repair or replace.

A faulty compressor can cause a host of problems. Some more apparent signs include leaking refrigerant, damage to the compressor, and loud noises such as rumbling, rattling, and clicking.

The easiest way to check the compressor is to take a multimeter and examine its terminals and wires. Look for burns or a lack of flow at the terminals, and make sure the unit is not Heating but has already been cooled down before you test it. If the compressor is shorted, it will surge electricity and overheat. This will cause the wires to contact one another and ground themselves.

Check the Refrigerant Levels

When your air conditioning system runs low on refrigerant, the compressor and other components must work much harder to compensate. This significantly strains the system and often leads to expensive damage or a complete system breakdown.

Professional technicians know to check the refrigerant levels regularly and address any issues contributing to the low levels – such as finding and repairing leaks or topping off the refrigerant. This prevents costly problems, saves energy, and helps to keep your system running longer.

To perform this critical task, take the appropriate safety precautions and follow all manufacturer guidelines and instructions for working with refrigerants. This includes wearing protective equipment and ensuring adequate ventilation. This is essential because working with refrigerants can release dangerous fumes.

Check the Fan

The fan is essential to the air conditioning unit that circulates cool air around your home. If the fan doesn't work, it can cause the evaporator coils to freeze up and make your system less efficient.

To check if your AC fan is working, walk outside to the condenser unit and look through the vents at the top. You should hear a humming sound from the fan and see the blades spinning. If the blades don't spin, there could be a problem with the fan motor or capacitor, which provides power to the fan. A trained technician can replace the fan motor or capacitor quickly. They can also test the capacitor to ensure it's delivering power to the motor.
