In this section, we will review the steps that almost any homeowner can perform. While these steps may seem not very important, performing them on a regular basis has proven to help extend the health and life of your system and cut down on energy bills.
External Unit Cleaning (Condenser and Compressor)
Step 1 – Disconnect Power to the Unit
Before performing any air conditioning maintenance, always disconnect power to the AC system to ensure your safety. Turn off the breaker and unplug the unit if possible.
Step 2 – Remove Debris and Clear Surrounding Area
Inspect the outdoor unit, also known as the condenser and compressor, for debris like leaves, branches, and dirt. Clear at least a two-foot radius around the unit for proper airflow.
Step 3 – Clean and Align the AC Fins
Gently brush the AC fins with a soft brush to remove dirt and debris. Straighten bent fins with a fin comb to improve airflow and overall efficiency.
Step 4 – Clean the Condenser Fan
Remove the fan cage from the outdoor unit and clean the fan blades using a damp cloth or a vacuum cleaner with a soft brush attachment.
Step 5 – Clean the Fins
Using a garden hose, spray the fins from inside the unit to remove accumulated dirt. For stubborn dirt, use an AC coil cleaner solution and follow the manufacturer’s instructions.
Air Filter
A clean air filter is the first line of defense against dirt and debris in your AC. Air filters are pretty easy to find at hardware stores, or you could order one online. Always remember to check your service manual for the correct style and size.
You can also pull the current filter out and take a look at that. We recommend buying a few at a time so you don’t have to run to the store every few months.
Importance of Regular Filter Maintenance
Air filter maintenance is essential for the efficiency and longevity of your air conditioning system. It also helps keep the air inside your home clean. Regularly changing filters prevent dust and debris from clogging the evaporator and condenser coils, reducing strain on the system.
When to Replace Your Air Filter
Typically, replace your air filter every 30 to 90 days. Factors like pets, allergies, and living in a dusty area can require more frequent replacements.
How to Replace the Air Filter
Locate the air filter in your AC system, remove the old filter, and replace it with a new one, ensuring it’s facing the correct direction.
Choosing the Right Air Filter for Your Home
Choose an air filter with the appropriate MERV (Minimum Efficiency Reporting Value) rating for your home’s needs. Higher MERV ratings provide better filtration but may reduce airflow. Looking at your current filter is a good way to figure out what works best.
Factors Affecting Filter Lifespan
Several factors affect filter lifespan, such as pets, allergies, and environmental conditions. Monitor your filter regularly and adjust the replacement frequency accordingly.
Checking Thermostat for Accurate Operation
An essential part of the AC System Maintenance Checklist is ensuring the thermostat functions properly. Test the thermostat by setting it to cooling mode and lowering the temperature. If the AC doesn’t turn on, check the batteries or call a professional.
Professional Air Conditioning Maintenance Checklist
Some tasks should only be done by a qualified, licensed technician. Internal system parts, electrical workings, coolants, and ductwork repairs require the kinds of expertise – and in some cases licensing – that only a qualified technician can perform.
Routine Inspections and Maintenance
Professional AC Maintenance Checklist
To keep your air conditioning system running efficiently, it’s essential to perform regular preventative maintenance. Routine inspections can help identify potential issues before they become more significant, saving you time and money in the long run. It also keeps your home more comfortable! A professional AC maintenance checklist should cover:
- Inspecting and cleaning filters, coils, and fins
- Checking electrical wirings and controls

How can I improve my AC cooling?
There are a few ways that the homeowner can improve the AC cooling in your home.
- First and easiest – Check your air filters to make sure that airflow is not impeded by dirt, debris, pet fur, or dander.
- Second – Make sure your outside units are free and clear of debris around the intake areas.

- Fourth – If none of these DIY recommendations work, contact your AC specialist for a service call. Since you have already performed the base checks, he or she can get right down to the solution and have you up and cooling in no time.
How do I keep my outside AC unit cool?
Keeping your outside AC unit cool is an important step to take for the health of your AC system. Consider planting evergreen bushes suitable for your planting zone that will not drop needles, such as Skip Laurel. They provide a lush evergreen cover that is deer resistant and hardy enough for our Illinois winters.
If planting is not appealing to you consider installing an awning or tightly woven decorative fencing. Radiant heat coming off of brick or stucco can really stress your outdoor unit.
What happens if an AC is not used for a long time?
If you are not using your AC for an extended period of time, there is no need to worry. Modern air conditioning units were built to lay unused for months at a time. In fact, they are so durable that they can even sit unused for a few years. The only requirement is that they still need their regular maintenance checks and inspections. There is no getting around that! Reliable AC maintenance In Gilberts, IL.
