How Can You Prepare Your Air Conditioner for Fall?

Fall weather is a welcome relief after another hot San Antonio summer, but along with cooler weather comes additional home maintenance. While giving your air conditioner time off, it’s important to protect it from the elements and prepare it for winter. In addition to prolonging the lifespan of your equipment, performing fall maintenance can help reduce repair costs and boost efficiency. Here are some great tips to get you on your way.

Change The Filter

A dirty filter prevents the flow of air throughout your air conditioner, decreasing efficiency. Once the filter is unable to trap particles and debris, they can make their way through the system, damaging parts while reducing the ability of your A/C to absorb heat. Clean or replace your air filter every few months during cooler weather.

Clean Your Coils

Evaporator and condenser coils gather dirt over time, insulating them while reducing airflow and heat absorption rates. A thorough cleaning, inspection, and refrigerant check are all part of a comprehensive annual maintenance plan, which can also help detect small issues before they become big ones.

Look Around

Keep the area surrounding the outdoor unit clear of obstructions, such as foliage, leaves, or other debris. Experts recommend a clearance of at least two feet around and four feet above the A/C, which also allows for ease of maintenance.


Fall is a great time to consider upgrading your A/C to a newer, high efficiency unit, particularly if repair or energy costs have been escalating, comfort levels are waning, or if your existing unit is older than 10 years.

Reset Your Thermostat

Changing temperatures warrant an adjustment on your programmable thermostat settings. Remember to switch over from “cool” to “heat” when the time is right. In addition to increasing comfort levels, you’ll also save on energy consumption.
