Air conditioning repair is an important service for your home’s heating and cooling system. A poorly maintained system can cause damage to your home and health problems.

 

There are many types of air conditioning systems. Some are more complicated than others. If you aren’t sure how to fix your unit, it’s best to call an experienced technician for help.

 

Some repairs are do-it-yourself projects that you can perform yourself, while others are complex jobs that only a trained AC repair professional should tackle. The type of repairs you can do depends on the system’s make and model, and how familiar you are with its internal components.

1. Clean the condenser coil and fins

 

A buildup of dirt can reduce the efficiency of your ac unit by making it work harder than it needs to. It can also block airflow and increase energy consumption. If you notice any signs of dirt around your ac unit, use a garden hose or other sprayer to remove it from the condenser and coils.

2. Change the air filter

 

You should clean your air filter on a regular basis. Clogged filters can cause your ac to work harder than it should and lead to costly air conditioner repairs.

3. Recharge the refrigerant in your ac unit

 

Most air conditioning systems use a coolant called Freon to run the system. If your system has low Freon levels, it will not cool properly and you may not be able to get the desired temperature. If you suspect that your ac has low Freon, contact a qualified AC contractor to recharge it for you.

4. Test the electrical components

 

A qualified HVAC technician will check for proper voltage and ohms resistance. He or she will also check the contactor switch and contactor coil.

5. Install a new fan motor

 

A professional AC service technician will replace the fan motor if it is not functioning correctly. It costs about $150. It is usually the most common part to break, so it’s worth replacing sooner rather than later.

6. Test the compressor and start/run capacitors

 

The most commonly failed parts of a ac system are the contactor relay (the on/off switch) and the capacitors that turn the compressor on and off. The contactsor relay and capacitors are inexpensive and easy to find, so if your ac system is more than five years old and you haven’t replaced these yet, buy them and replace them right away.

7. Test the thermostat

 

A skilled HVAC technician can test the thermostat to make sure that it’s in good condition and working well. This will ensure that the air is consistently comfortable in your home.

8. Recharge the thermostat and ac system

 

A trained HVAC technician can recharge your ac system to help it operate more efficiently. This can improve your home’s air quality, save you money on your energy bills and provide peace of mind. It can also prevent future repair costs. You can get more enlightened on this topic by reading here: www.britannica.com/technology/HVAC.
