Tips on Replacing Your Dirty Reverse-Cycle Air Conditioner Filters

Posted on: 11 May 2017


For homeowners who want to enjoy year-round temperature control service, reverse-cycle air conditioners are an appropriate choice of HVAC equipment. During the hot sunny months of the year, these air conditioners provide cooling service, whereas during the cold winter months, they do the exact opposite — warm up the living area. Because reverse-cycle air conditioners are often being operated almost throughout the year, it is easy to overlook that they too need servicing, just like other types of air conditioning equipment. As a matter of fact, reverse-cycle models may require slightly more maintenance attention because they are generally busier than the other air conditioner varieties. 

If you've installed a reverse-cycle air conditioner in your home, one of the things you'll need to do to keep it running efficiently year in and year out is to replace dirty filters. Air conditioner filters prevent airborne dirt particulates from entering the system, and they can result in system inefficiency or failure if they are not cleaned as required. 

Here's how you can effectively remove and replace a dirty air conditioner filter and keep your equipment working reliably for longer. 

Turn OFF the system

Air conditioners are electrical equipment, and as a general rule, no electrical equipment should be repaired or maintained when the power supply hasn't yet been cut OFF. This is primarily because the individual working on the equipment can easily be injured by live electric current. Or, the person may cause a fire or explosion if an electrical fault arises. Therefore, the first thing you should do before touching any part of your air conditioner is to cut power supply at the mains electricity or the place where you are receiving power from.

Locate and remove the filter

The next step is to locate the filter so you can remove it. On most modern air conditioners, you can find the filter located behind the return air duct that allows air to enter the system. But you can always consult your air conditioner's user manual just to be sure. Once you've found the filter, use a screwdriver to remove it.

Install the new filter

Before you can discard the old filter, make sure the replacement filter fits perfectly and it is the right type. If you're unsure about what type of filter you should purchase, you can always visit your air conditioner manufacturer's website to see what they recommend. Installing the new filter is rather easy — you simply screw or fasten it where you removed the old filter.
