Do It Yourself A/C Maintenance Tips

Keeping up with maintenance can also increase the life and efficiency of your air conditioning system, saving you more money over the years.

Many people choose to save money on expensive air conditioning service costs by doing their own basic maintenance on their window units and central air conditioning systems. This is a common practice to which entire Do It Yourself forum communities have dedicated tips and instructions for the motivated home owner.

Getting Started

Taking care of your A/C is not hard and does not take a lot of time. But it will be time well spent, especially if your air conditioner is running a lot during the summer. You don’t need any tools to do the job, just a little common sense and a few minutes of time.

First, if you are unsure about how to do these tasks, talk to a professional A/C technician and have him show you what needs to be done. Then, you can do it yourself the next time. If you have a manual, that can be a useful resource, too.

Whenever you do any maintenance on your A/C, start by turning off the power at the thermostat and also the breaker switch (pictured below). Note: While examining your A/C system and opening the unit, be careful not to injure yourself on any sharp metal edges that might be inside your air conditioner when you take the cover off.

Changing Your A/C Filter

One of the easiest and perhaps most important maintenance jobs is to check the filter and see if it needs replacing. The filter should lift out without the need for any tools. Once you have it out, hold it up to the light and see if there is dirt, dust, or pet hair clogging it. You should be able to see light through it. If not, it is time to change it, or wash it if it is reusable.

Changing the filter in your A/C should be done at least every three months when it is in service. For pet owners – especially those with long-haired cats or dogs – changing the A/C filter every month or other month is a must. Dirt particles from the air are trapped in the filter and will cause the machine to work harder, requiring more energy and raising your electric bills. In Florida, a clean A/C filter is the key to reducing indoor air humidity, which is hampered by dirt and debris. By keeping the filter clean, you can save as much as 25 percent on energy bills during months when the A/C is in operation.

Its a good idea to have a spare filter on hand before you need one. Publix and other major grocery and convenience stores typically carry disposable filters of all sizes, as well as pet-dander and allergen specific models. If you are running your air conditioning system everyday, check the filter more frequently, especially during the summer months. In areas with heavy particulate matter in the air, a filter can clog up in as little as two weeks.

How to Clean A/C Coils

The next maintenance task is to look at the coils and fins on the unit. The A/C coils are typically protected by a grill that has been screwed in, so keep a screwdriver handy for easy removal. Once you have exposed the coils on your air conditioner, softly brush them from side to side to remove any built-up dirt or leaves. Tip: use a hand clipper and cut away any bushes or plants that are touching the unit. Also, be careful not to apply too much pressure to the coils, or bend them in any way, which could damage your air conditioning system. Also check to see that water is coming out of the drain when the A/C is operating. If it is not, call your repair person for help.

Checking the Freon Levels

Freon is the stuff that’s responsible for keeping the air that is blowing from your system nice and cold. Too little of it and the air in your house will remain stagnant and warm, regardless of what temperature you set your thermostat to. When it comes to A/C maintenance, taking care of the freon is an advanced task that is better left to the professionals. Under no circumstances should you consider recharge or flush your refrigerant lines without the proper tools and expertise.

However, a quick check up to make sure everything is working the way it should be is a simple enough task. A/C coolant line insulation can become worn or damaged from prolonged outdoor exposure, and is easy to see.

Schedule Maintenance for Your Air Conditioner

Regardless of whether you hire an A/C company or choose to do the maintenance yourself, regularly checking the condition of your A/C system can greatly extend the lifetime of your system, in addition to maximizing efficiency and reducing energy costs.

Having a professional air conditioning technician service your A/C each year, along with these fast and easy maintenance tasks, will keep your cooling system running efficiently for a lot longer. You will stay cooler yourself, too, in more ways than one.

  1. Good points, but you really need to turn the breaker off to the indoor unit as well as the outdoor unit when washing the condenser coil. Watch how this guy is washing the condenser coils with the disconnect box open which is a good way to get shocked.
