Repairing an AC can be quite expensive and replacing the AC is an even bigger challenge. Not only is the AC running for hours on end during the summer months but it is also exposed to heat, dust, moisture, debris, and all kinds of other harmful elements. Using these tips to take care of your AC can help you reduce maintenance costs and increase uptime.

1.  Check Sockets

ACs draw a lot of power from the socket, especially when they start. They also run for hours on end which means the socket goes through a lot of wear and tear. Using a multimeter, you can check the voltage in the socket and should also visually inspect the condition of the socket and plug. Low or high voltage or fluctuations due to a poor connection can cause severe damage to the AC unit.

2.  Comb Fins

The fins on the external cooling unit help to channel air towards the internal components. These are made from aluminum which means they are soft and can easily bend and deform. Investing in a fin comb is a great way to save on ac maintenance as you can properly straighten out the fins and improve airflow. This will save your unit from overheating and getting damaged.

3.  Clean Condenser

The condenser coils and evaporator coils are the brains of the system. This is where refrigerant changes state to provide the cooling effect. Properly cleaning these coils helps the refrigerant change from hot to cold more efficiently. If you are getting poor cooling, this one trick alone can make a huge difference. It’s safe to use water on these coils. A pressure washer works very well.

4.  Replace Filters

Filters in the AC can get clogged and start to smell. They can also get moist and start to harbor fungus and mold which can lead to respiratory problems. In both HVAC systems and AC systems, you can clean or replace the air filters. Check your filters every few weeks and clean or replace them as needed.

5.  Top-up Gas

The AC uses gas to cool the evaporator coil that provides the cool air in your house. If there isn’t enough gas in the system, it can’t provide proper cooling. Over time and through micro leaks in the system the gas volume decreases. Have a professional check the system and get your gas topped up if necessary.

6.  Cover Piping

There is a lot of line loss through the piping in the AC system, specifically the pipes that are exposed to the environment. Covering these pipes with insulation foam can help reduce these losses and increase the overall efficiency of the system. If the pipes aren’t insulated, or the insulation looks worn out, install or replace it.

There is no harm in running the AC continuously. Most commercial offices never turn off the HVAC system. However, to get this level of performance from the system you need to make sure all the components are in great condition.

Regularly cleaning the AC, making sure everything is in good condition, and installing the right bits and pieces in the system will ensure it works as it should. If you aren’t sure about a certain thing always consult an expert or you could end up permanently damaging the AC.
