5 TYPES OF AIR CONDITIONER PROBLEMS

Listed below are five common AC-related issues that homeowners can most frequently come across. These are problems that should be addressed promptly to avoid larger and more costly air conditioner issues.

1. OUTDOOR WATER LEAK

On hot summer days when your AC unit seems to be working harder than usual, you might notice a puddle of water outside under your unit’s compressor. This could be because of several reasons: improper installation, a broken condensate pan, dry air filter, or bad AC seal, to name a few.

2. REFRIGERANT LEAKS

Refrigerant, also known as freon, is responsible for cooling the air inside your air conditioning system. The performance of your AC remains top-notch if the refrigerant charge matches the manufacturer’s specifications. We offer air conditioning repair services for refrigerant leaks. If you do not fix the refrigerant leak quickly, your system will become less efficient.

3. FROZEN EVAPORATOR COILS

In a properly functioning system, the evaporator circulates refrigerant vapor at about 40 degrees—the optimal temperature to extract heat from the airflow passing through the coil but never frigid enough to produce ice.

When ice accumulates on the coil, it prevents the refrigerant in the coil from absorbing latent heat. Damage may occur as the blower fan strains to pull air through the ice-obstructed coil, often overheating, or the compressor is dangerously overstressed as the A/C runs continuously, never cycling off. You’ll need to call our certified HVAC technicians to perform an air conditioning repair and fix the problem.

4. FAN FAILURE

The outside unit of your air conditioner transfers the heat from inside to outside through a fan. If the fan located outside of the house does not perform efficiently, proper heat transfer does not occur. As a result, the air conditioner’s compressor may overheat or trip the safety load. Worst case scenario? This may cause internal damage to the compressor, which could lead to an air conditioner replacement.

5. DIRTY FILTER

If you notoriously forget to change your air filter, you’re not alone. In a perfect world, you’d change an air filter every three months. If you have pets or suffer from allergies, you’ll probably opt to change it every seven to nine weeks. An air conditioner filter may seem insignificant, but it plays an important role in keeping the airflow through your house clean and free from dust and pollutants.

4 MAIN COMPONENTS OF AN AIR CONDITIONER

EVAPORATOR COIL

In a conventional split-system air conditioner, the evaporator coil is located inside the home or nearby the air handler where the blower fan is. Cold refrigerant vaporizes inside the evaporator and draws heat from warm return airflow. Coils should be cleaned each year for maximum cooling efficiency. As the air conditioner runs, the compressor’s job is to pull cold, low-pressure liquid refrigerant through the tubes in the evaporator coil.

Before the refrigerant enters the evaporator coil, it passes through the expansion valve. The valve relieves pressure which quickly cools it. If you need help cleaning your evaporator coils, our staff of licensed technicians offers air conditioning repair services in Wayne, West Chester, Broomall, Drexel Hill, and other areas in Pennsylvania and Delaware.

COMPRESSOR

This is typically the noisiest component. The compressor’s job is to receive refrigerant from the evaporator coil and prepare the refrigerant to release heat at the condenser coil.

CONDENSER COIL

Where the evaporator coil extracts heat, the condenser coil releases heat at the outside cabinet. The evaporator coil gets heat from indoor air, and the condenser coil expels heat into the outdoor air.

FANS

An air conditioning system has two fans that pull airflow over the evaporator and condenser coils. The fans are in the outdoor unit and help suck in and expel the air. With a traditional cube-style unit, you can easily see the fans spin while your unit runs.

3 TYPES OF AIR CONDITIONER NOISES

1. WHISTLING NOISES

A whistling air conditioner is a tell-tale sign of duct leaks. As the cooling system forces air through the ducts and into your living areas, air that’s pushed through leaks in the duct system will make a whistling noise. If you’re uncomfortable tackling this job with masking tape, call your HVAC contractors at WM. Henderson to inspect and seal leaks.

2. CLICKING SOUNDS

Electrical parts tend to click when air conditioners start-up and shut down. Clicking noises may also be a sign of loose parts brushing against other components while the system is running. Our staff offers dependable air conditioning repair services and have the equipment required to fix noises in your system. Give our technicians a call by phone or book online to receive help with a broken system. Constant clicking is abnormal and may indicate a defective control panel, poor electrical connections, or a failing thermostat. Schedule a service with your local WM. Henderson contractors.

3. CLANKING NOISES

Clanking air conditioner noises indicate a component is loose within the AC unit. A certified technician will determine if the clanking originates from a failed component or if the fan blades are unbalanced. Regular air conditioner maintenance can help you detect underlying problems that possibly decrease the efficiency of your system or may lead to AC failure.
