Don't overwork your air conditioner, whether it's a whole-house or a single-room unit. Follow these guidelines to maintain your air conditioner functioning properly so that your home remains cool throughout the season.

However, firstly you need to understand something important!

Understand How Your House Air Conditioner Works

An outdoor unit (compressor/condenser) that sits adjacent to your home and an inside unit (evaporator) that's situated in a central duct near your furnace are the two primary pieces of most central air conditioners. The interior unit will be in the air handler if you have a heat pump instead of a furnace. Follow the same maintenance procedures outlined here. Use the owner's manual to figure out how to operate your furnace if it differs from the one pictured or if you have a heat pump. The fundamental components will be the same.

So, are you ready to get know some of the easy tips on maintaining your home cooling system and air conditioning unit?

Let’s get to know more…

1)Maintain a clean environment

Using a soft-bristle brush, vacuum the fins of your air conditioner. It's worth noting that they're delicate and can easily be bent or crushed. To access them on many systems, you'll have to remove and raise a metal box. For instructions, see your owner's manual, and raise the box carefully to avoid damaging the fins.

2)Repair a Sinking Air Conditioner Pad in Your Home

Over time, the concrete pads behind air conditioners and heat exchangers in homes tend to settle. It's fine if the pad sinks as long as the copper coolant tubes and electrical wires aren't strained and the unit remains dry and level. You'll need to take action if it continues to sink and pulls the lines tight, or if water puddles around the unit.

3) Get a Thermostat That Can Be Programmed

In today's state of AC technology, a programmable thermostat is a must-have. Programmable thermostats allow you to set temperatures for different times of the day and have the temperature automatically fall when you need it the most, saving you money and allowing you to control your cooling without continually hanging over the dial.

4) For home air conditioning units, install an in-line duct booster.

A duct or vent booster fan can improve the flow of cool air into a room that has forced-air cooling but is still hotter than the rest of the house. There are two types of booster fans available. An in-line duct booster fan (pictured) is designed to fit inside the duct of the room being cooled. When your cooling system runs, the fan is mounted near the outlet and automatically turns on.

Booster fans for ceiling, floor, and wall registers sit directly on top of or replace them. You can configure it to function automatically, control it with a switch, or use a remote control, depending on the type.

5) Make a Noisy Air Conditioner Quiet

If you already have a modern condenser, the compressor is most likely the source of the loudest noise. (Newer units have very quiet fans.) Obtain a sound blanket for your model from the manufacturer or purchase a universal blanket (search online for "compressor sound blanket"). It's simple to set up. You won't be able to hear the noisy fan if you cover an old unit with a blanket.

6) Unclog the Condensate Drain Tube

When you see water puddling around the furnace while the air conditioner is running, you have a clogged condensate drain tube. Bacteria in condensate from air conditioning coils can develop slime and clog the condensate pan drain tube.

7) Checklist for the Summer

To stay cool, make sure your air conditioner is in good operating order. When it's hot outdoors, you want your house to be comfortable and cool inside. Before the summer heats up, use this helpful checklist to examine your HVAC system and schedule any necessary AC maintenance or repairs.

8) Filter should be replaced.

Switch off the furnace's power at a nearby switch or at the main panel. Then remove the furnace filter and inspect it for dirt accumulation. If required, alter it.

9) Is Your Air Conditioner the Correct Size?

The size of an air conditioner is determined by the number of cubic feet it must cool. This is especially crucial when buying a new air conditioner or upgrading your home. If your air conditioner is rated for a smaller size than yours, it will work too hard to chill the air, wear out faster, and struggle to keep up with the thermostat's demands.

10) Consider purchasing a whole-house fan.

For almost a century, whole-house fans have kept homes cool. The basic layout is straightforward: An attic fan pulls cooler outside air in through open doors and windows and pushes hot air out through attic vents. This quick air exchange not only removes built-up heat but also provides a pleasant breeze (big fans can purge a house of hot air in two to three minutes).

11) Controlling Heat Through Windows

A significant amount of heat enters the home through windows, particularly open windows. Pay attention to your windows as well if you truly want to control the temperature in your home. During the hottest portions of the day, keep them closed and covered with blinds or drapes—especially windows that are now facing the sun.

12) Examine the Insulation

Replace any broken or rotten insulation around your exterior AC lines to boost the effectiveness of your unit.


Air conditioner and home cooling maintenance is critical and should not be overlooked. Preventative maintenance, while it may not seem required at times, is preferable to having to replace a malfunctioning cooling system.The key is to get in touch with us on regularly scheduled service calls.
