Air Conditioning Maintenance Checklist

Most homes in Australia have some kind of air conditioning. In fact, it is more common in Australian homes to have an air conditioning unit than a dishwasher, garage, or other appliances. 

However, only 42% of homeowners call a professional to perform routine maintenance on their air conditioner. Some homeowners rely on DIY maintenance, which is sometimes unreliable because they can’t access every part of the unit. 

Here are some of the benefits of regular air conditioner maintenance: 

 

  • Air conditioners that go through regular maintenance last 40% longer.
  • Cleaning your air conditioner makes it more efficient by reducing the stress and pressure caused by dust and debris buildup on your unit. 
  • Cleaning your AC unit reduces the need to work harder, thus shaving some dollars off of your energy bill.
  • Avoid bigger issues and complete breakdowns by having your unit regularly cleaned by a professional air conditioning company. 
  • A clean AC also keeps the air circulating inside your home clean and healthy.

What’s Included in Professional Air Conditioning Maintenance?

Most homeowners think that DIY HVAC cleaning is enough to keep the unit performing efficiently. But what you don’t know is that it is not enough. Although cleaning your air conditioner personally helps in removing some dirt and dust on your unit, having a professional check ensures that all aspects of the unit are looked at. 

If you have a qualified HVAC technician is going to inspect your air conditioning system, the following components will be checked: 

Thermostat Settings

The HVAC technician should ensure that your thermostat is installed correctly and away from all heat sources, such as solar rays, light bulbs, and other heat-producing appliances.

Electrical connections

Electrical connections should be tightened and check if they are operating safely. This also helps improve the lifespan of your air conditioning system.

Lubricate moving parts

This step is important because friction can cause unnecessary damage to moving parts. Lack of lubrication can cause your system parts to break down quickly, which you need to have repaired or replaced as soon as possible. 

Check and clear condensate drain line

Your HVAC technician should ensure that your condensate drain line is clean and clear. If the drain line becomes clogged, water leaks and other moisture problems can be expected. Moisture is the perfect breeding ground for bacteria and mold, so call an air conditioning technician to check and clear your condensate drain line regularly. Leaks can also happen if you have a cracked condensate drain pan. Your air conditioning technician should repair or replace any leaking condensate drain pans.

Check system controls

Checking your unit’s system controls ensures proper cycling and safe operation of your air conditioning system. It’s important to check whether your system is starting, operating, and shutting off properly.

Check, clean, and change your air filter

A working and clean air filter is important for better indoor air quality. You don’t want to inhale air that passed through a dirty filter. Although owners are able to change the filter on their own, an HVAC expert might help in making sure you are using the most suitable filter for your unit.  

Fix refrigerant leaks and recharge refrigerant

If your air conditioner’s refrigerant needs to be charged, you need an HVAC technician to do that.  He will also make sure that your refrigerant meets manufacturer specifications. Too much or too little refrigerant can cause problems with the moving parts of your air conditioning system, such as the compressor and condenser.

Here are the other aspects that your air conditioning technician will look at: 

  • Measuring amperage and voltage of Blower Motor for proper operation
  • Lubricating and inspecting the Bearing for wear
  • Inspecting indoor coil
  • Flushing and treating Condensate Drain with anti-algae
  • Inspecting Condenser Coil
  • Inspecting Safety Devices for proper operation
  • Inspecting Electrical Disconnect Box for proper rating and safe installation
  • Inspecting and tightening Electrical Wiring connections
  • Testing and inspecting contactors for burned or pitted contacts
  • Inspecting electrical for exposed wiring
  • Inspecting and testing capacitors
  • Inspecting fan blade
  • Cleaning condenser coil and removing debris
  • Inspecting service valves for proper operation
  • Measuring Supply/Return temperature differential
  • Inspecting ductwork for energy loss
  • Monitoring and measuring amperage of Compressor
