10 most common problems with air conditioning and how to fix them

1. AC filters

One of the typical reasons why air conditioners do not work properly is a clogged or dirty filter. Follow the manufacturer’s suggestions on how often you need to replace your air filter. Some are monthly, others every three months, while some are reusable and must be cleaned if they are dirty. One way to determine if a filter needs to be cleaned is to check if light passes through. If not, it’s time to clean it. Dirty filters not only reduce the air flow, but can also cause the AC unit to freeze.Best DC inverter AC in Lahore is more reliable then others.

2. AC thermostat

Another simple solution is to make sure that your thermostat (which controls the temperature setting in your house) is switched on, the inside is clean, the level is, is not affected by sunlight and has the correct setting. If the problem persists, there may be another problem.

3. AC coolant leaks

When the coolant starts to leak in the air conditioner, the device does not work properly and the temperature fluctuates. The location of the leak has an impact on the cost of the repair, so it is advised to have it trained annually by a trained AC technician.

4. AC drain

Just like the filter, the drain pipe can become clogged with dirt, dust and lint. If it becomes clogged, the drip tray will flood and water will leak that could damage the AC unit or what is around your pan.

5. AC breakers or fuses

The circuit breakers and fuses protect the motor or compressor of the AC unit against overheating. Often when an engine dies, one of the first parts that the HVAC technician checks is the breaker.

6. AC capacitors

Without capacitors, the motors that drive the compressor and fans will not work. The starting capacitor sends a shock to activate the motor, while the starting capacitor delivers a series of shocks to make the motor work. The AC unit does not work efficiently if one of the two burns out.

7. AC compressor

The compressor supplies energy to the coolant and drives it through the coils to perform heat exchange. If the compressor does not work, the AC unit will not cool your house. If there is not enough coolant, the compressor becomes hot and eventually it sticks. If there is too much, the refrigerant returns to the compressor, which may cause it to malfunction.

8. AC evaporator coils

Evaporator batteries absorb heat in the air and send it through a series of air ducts as cold air into the house. Bobbins can get corroded, but if they are inside, they usually only require maintenance every three years.

9. AC condenser batteries

Condenser coils are located outside with the compressor, so that they can become dirty due to the elements. They can usually be cleaned once a year with a water hose, but if they become too dirty, an HVAC technician should clean them with a chemical cleaner.

10. Worn AC switch

In an AC unit there are contactors for the compressor, the fan motor and the condenser fan motor. They make an electrical connection that starts the engines and the compressor. If there are sparks and pits on the switch, it will be difficult for electric current to start the motors.

 

Tips for a healthy air conditioner

 

Clean and / or replace air filter on AC unit

Replacing your air conditioner air filter (or cleaning it if you have a reusable filter) is one of the most important regular tasks in AC maintenance. It should be done every month during seasons with a lot of use (such as summer and winter) and once during fall and spring.

Check the wiring and AC components

Before working on an air conditioner, ALWAYS start by turning off the power to the unit, which can be done via the service connection on your outdoor unit or on the main break panel of your home.

Then remove the access panel from your condensing unit and see if you see any signs of overheating – melted insulation on wires, blackened or burned wires, and the like.

You can also check all electrical connections to make sure they are tight. If you have an electrical test meter, you can check the capacitors in the device.

Check condenser fan

Turn off the power to your air conditioner unit and check the fan on top of the outer condenser unit to make sure it is still in good condition. Replace the fan blades if cracks or chips are visible in one or more of the blades.

If you have an older air conditioner, the fan motor bearings may also need to be oiled regularly.
