  • The air conditioning system is powering on and off randomly.
  • Excess humidity of moisture in the room.
  • Unusual loud noises from the cooling system.

Consequences of Neglecting Air Conditioner Maintenance

Most homeowners assume cleaning the AC would be time-consuming. Thus, they often overlook this power-intensive home appliance. Arguably, the AC is the most important device, especially during summer. So, try to keep it a tip-top shape to avoid unwanted repairs.

Here are the issues that can develop due to inadequate AC maintenance:

Excess Dust Accumulation

An AC not only cools down the room temperature but it’s also responsible for filtering out dust. The filters get clogged with dust or debris over time, reducing efficiency. Clogged filters can be the breeding ground for pests. Thus, you should clean these units properly to keep these problems away.

Increases the Risk Level

Using an ill-maintained air conditioner can be risky for homeowners. However, you can fix these safety concerns with routine maintenance. An AC’s refrigerant may leak due to overuse, which can further pose severe health risks.

Most advanced air conditioners contain harmful R-22 refrigerants. This refrigerant gas can cause nausea and other respiratory issues. Besides, if you don’t repair the referent on time, the leaked gas can cause skin irritation.

Switch off the AC if you notice any of these symptoms. After that, contact an expert and replace the problematic AC unit without delay.

Causes Fire Hazards

Air conditioner systems that aren’t properly maintained can develop defects over time. The device may overheat with dirty condenser coils, increasing the risk of fire hazards.

Moreover, the wire insulation can break without proper maintenance. If the motor runs for a prolonged period, it can lead to an “electrical” short.

More Repairs and Replacement

Do you know the AC units can stop working due to the lubrication issue? Air conditioner components, like fans or coils, require periodic oiling; otherwise, these units may get damaged or become unresponsive.

Thus, hire an AC maintenance expert to lubricate these AC units. It will keep the fan or coil in good condition and offer efficient cooling.

Damaged Ductwork

The longer the AC goes without maintenance, the higher the chance of breaking down. Some parts of the cooling system may even get damaged over time. It can affect the device’s performance if you take a long time to repair these units.

Let’s take the AC’s ductwork, for example. If there is a hole in the ductwork, the cool air will escape through this damaged part. This will increase the humidity and moisture level in the room. However, maintaining the device can prevent the ductwork from getting damaged.

Best Air Conditioner Maintenance Tips Homeowners Should Follow

Like other electronic devices, AC also requires regular servicing and proper attention. Routine maintenance is essential to get sufficient cool air during the summer months. Besides, you can prevent the spread of air-borne diseases by maintaining the device.

Here are the maintenance tasks that you must perform to keep the AC in its best condition:

1.    Check the Power Connection

It’s essential to check whether the AC is on or off before starting the maintenance work. Additionally, you must note in which position the isolation switch is.

Is the isolator switch in the “ON ” position? It indicates the air conditioner is still on. Turn off the isolator so that electricity can’t run through the device.

Note that just because the isolator off does not mean the power is off. Broken isolator switches can allow power to flow into the units even if it is in the “OFF” position. It could be risky to clean the AC units when the power is on. Thus, repair the faulty isolator switch first before making the AC clog-free.

2.    Inspect and Clean the Air Filters

Cleaning the clogged filters helps you to maintain the air conditioning system. Do you know how to clean this AC unit? First, you have to open the unit using a screwdriver and remove the filter. Some ACs have multiple filters; thus, check and remove them.

Don’t know where the air filter is located? Check the product’s manual for help. You can also access the manufacturer’s website to find the filter’s location. However, remove the dust build-up with a vacuum cleaner if you have found the filter. You must wash the filter if the vacuum hose doesn’t remove the dust.

How to Clean the Air Conditioner’s Clogged/Dirty Filters?

Fill a bucket with water and mix white vinegar in it. Pour the water and vinegar solution into the filter to remove the dust build-up. Allow the AC filter to soak in the solution for at least 1 hour. Rinse it off with water and let it dry for 20-25 minutes.

Additionally, you can use a garden hose to clean the dirty filters. Don’t exert excess pressure while cleaning, it could damage the filter. Did you notice any sign of wear and tear in the air filters? Instead of reinstalling the filter in the AC, consider changing it.

3.    Clean the Condensate Drain

A clogged condensate drain can cause water leakage issues. Blockage can occur when algae or mould growth inside the drain line. Components from the indoor unit, such as insulation, can also clog this unit. Thus, you must clean this unit to remove the clog.

Here is how homeowners can make the condensate drain clog-free:

  • Locate the air conditioner’s condensate drain line first
  • Find the T-shaped vent on the drain line, remove the cap and inspect for blockage
  • Add ¼ cup of distilled white vinegar to the condensate drain
  • Use the water and dish soap mixture if you get the smell from the drain line
  • Let the solution dry for 30 minutes, and then rinse it off with water

4.    Check the AC Temperature

You must check the temperature differences between the supply and return air vents. The supply vent air may have a higher temperature than the return vent air. Contact an expert if you find these two vent air temperatures the same.

Use a calibrated thermometer to get accurate temperature readings. The AC works fine if the supply and return air vents have a 10-degree difference. However, if the temperature difference is more than that, the AC is at fault.

How should you check the Supply and Return Air Vent’s Temperature?

Are you using a digital thermometer? Hold it near the air vent for at least 30-60 seconds to get the accurate temperature. However, in the case of a glass thermometer, the time limit is approximately 7-10 minutes.

5.    Check the Insulation

Insulation around the AC’s copper piping needs to be checked daily. This unit reduces the moisture level and maintains heat exchange efficiency. Insulation also prevents the refrigerant from changing the gas into the liquid quickly. By doing this, the unit protects the AC compressor from damage.

An AC insulation is comparatively easier to find than others. It is black or white pipework which is connected to the outdoor unit. The latest air conditioners’ insulation is made with polyurethane or foam rubbers. However, you will find glass pipe insulation in the old air conditioning systems.

Other Essential Air Conditioner Maintenance Tips:

Refrigerant plays an integral role in the heat transfer process. Thus, you must keep this unit in good condition. If the refrigerant level is low, consider refilling it immediately.

You should inspect and test the AC controller functions. Replace its battery once or twice a year to ensure it’s working fine. Besides, homeowners must clean the split AC with a dry cloth, which will help keep the indoor air allergen-free.

Further, you also need to check whether the outdoor unit level is correct. If the unit isn’t levelled properly, you have to reinstall it. Besides, you must check the wirings and the pipeworks of the AC.

Ensure there is no duct leakage in the central air conditioning system. Adjust the thermostat settings and tighten the electric terminals, if required. Inspect and clean these units properly and keep the AC summer-ready. Go for it!
