A Complete Guide to Air Conditioner Maintenance

The filters, fins, and coils of the air conditioner require regular maintenance so that they can work efficiently and effectively for years and years. Neglecting the required maintenance that your air conditioner needs will lead to a steady decline in its performance while energy usage will steadily increase. At, we would like to recommend getting your air conditioner unit maintained and serviced once a year. Homeowners should do this in the spring so you can get the flawless service of your air conditioners during the hottest months of summer.


Here are more ways to help your air conditioner unit run efficiently throughout the year, improving your comfort and convenience.

Coils of Air Conditioners

The evaporator and condenser coils of the air conditioners collect dirt and dust over months. While the clean filters prevent the evaporator and condenser coils from frequent soiling; the coils still collect dirt over time. The continuous accumulation of dirt in the coils reduces the flow of air by insulating the coils. Further, it reduces its ability to absorb heat. Homeowners should check their loops and clean them every year to avoid such problems.

Homeowners should also take care of condenser coils that are outside. They should not allow these outside coils to get dirty as these can get dirty due to nearby foliage and dusty environment. Dirt collected on the outdoor condenser coils can be seen easily. Falling leaves, lawnmower, and dryer vents have the potential to make your coils dirty. You can trim the foliage, remove the debris and clean the area to allow for adequate airflow around your condenser.

Filters of Air Conditioners

The routine replacement or cleaning of your air conditioner filters will bring the most efficiency to your air conditioner unit. Clogged and dirty filters block the normal flow of air, thus reducing the efficiency of your system. With obstructed airflow, air bypassing the filter starts carrying dirt directly into the condenser and evaporator coils impairing their heat-absorbing capacity. When you replace a clogged, dirty filter with the clean one, then it helps you to reduce the consumption of energy by your air conditioner by 5 percent to 15 percent.

You can find the filters located along the length of the return duct in central air conditioners. The filters’ typical locations are in ceilings, walls, or furnaces and sometimes in the air conditioners itself. You can find the filters in the room air conditioners mounted in the grill and facing into your room. You can reuse some of the filters; however, some others need to be replaced. All these filters are available in a variety of efficiencies and types. Replace or clean the filters of your air conditioner every month. If you are using air conditioners continuously or are subjected to dusty and dirty conditions, it requires your frequent attention.

Condensate Drains

Clogged channels of drain prevent the air conditioners from reducing humidity. As a result, the excess moisture can discolor your carpets or walls.

Coil Fins

The aluminum fins on the condenser and evaporator coils bent quickly, thus blocking airflow through them. You can find the fin comb from the wholesalers of air conditioners to comb these coil fins and bring them back into their original condition.

Room Air Conditioners: Window Seals

When the cooling season starts, you can inspect the seal properly between the window frame and air conditioner to make sure whether it has made contact with the unit’s metal case. Moisture can cause damage to these window seals allowing cold air to escape from your home.

Prepare Your Device for Winters

You can either cover the air conditioner of your room or remove and store it. If you cover your central air conditioner’s outdoor unit, it will protect your unit from debris and winters.

Hire a Professional

There are occasions when your air conditioner may stop functioning all of a sudden. In such circumstances, it requires more than routine maintenance. You can immediately call an HVAC technician to find the reasons and get the immediate fix for your problems. A well equipped and qualified HVAC technician can adopt the below-given course of action:-

  • They use the leak detectors to check for any refrigerant leak and availability of enough refrigerant.
  • HVAC technicians don’t release the refrigerant to the atmosphere illegally; instead, they capture it and evacuate from your equipment.
  • They check for duct leakage and seal them in the central systems.
  • Also, these HVAC technicians measure the flow of air through the evaporator coils.

Apart from these, HVAC technicians check the thermostat’s accuracy, check oil motors and belts for wear and tightness, inspect the electrical terminals, tighten and clean the connections, and apply the required non-conductive coating. Also, they verify the correct sequence of electric control and the proper functioning of the cooling and heating system.
