Air Conditioning Maintenance: The Ultimate Guide

by Stewart Unsdorfer


You rely on your air conditioning system to keep your home cool and comfortable. Your A/C system requires regular maintenance to function efficiently.

Just like any other home appliance, your air conditioning unit is bound to show wear and eventually deteriorate, developing mechanical problems at some point during its lifetime.

Keeping your system running smoothly depends on proper attention to its maintenance and service needs. System maintenance can also save you money and headaches from unexpected breakdowns that leave you steamed! 

If you are looking to keep your home comfortable (and who isn't?), then keeping your A/C running is a must.

Let's take a look at what you can do, and when you need to call in the pro's, when it comes to air conditioner maintenance...




Chapter 1

How Your Air Conditioner Works

If you have recently moved from a home where you were using fans or window-mounted air conditioners, or you are thinking of installing a central air unit, you may not fully understand the central A/C system. Don't worry... here's what you need to know.



Chapter 2

Why Does My A/C Need Maintenance?

Regular A/C maintenance will not only extend the usable life of your unit, it will also save you substantial amounts of money on repair and replacement costs.



Chapter 3

How to Shut Off Your A/C Power

Turning off your air conditioner protects your equipment, but more importantly you. Always check to see if you've successfully turned off your system by attempting to turn heating and cooling on from your existing thermostat.



Chapter 4

How to Clean Your Outdoor A/C Condenser Unit

You should aim to clean your condenser unit once a year under normal conditions, but more often if there are an abundance of dandelions or other growth around your unit.



Chapter 5

How to Level Your Outdoor A/C Condenser Unit

Compressors that are not level may fail to function properly and need adjustment. You must be careful when it comes to moving your A/C compressor. You do not want to cause a refrigerant leak or damage the equipment.



Chapter 6

How to Clean Your Evaporator Coil

When evaporator coils get dirty, they won't be as efficient in providing your home with cold air or dehumidifying your home. Air that blows across the coils usually contains particulates, like dust and pollen, that can cause your air conditioner to function at a reduced rate as much as 30%.



Chapter 7

What if Your Evaporator Coil Drain is Clogged?

One of the most common reasons an air conditioning pro is called because the condensate drain line has been clogged. Simple maintenance, once or twice a year, can save you money and requires no special tools. 



Chapter 8

Changing Your Blower Filter

It's important to make sure you replace your home air filters regularly. This helps your air conditioning equipment running properly, and efficiently.



Chapter 9

When You Should Call a Pro

Keeping your system running smoothly depends on proper maintenance and service needs. Some problems need the attention of a certified technician. They have the experience to diagnose the problem quickly and get your system up and running safely.
