As the weather cools down and you switch from air conditioning to heating, it’s important not to overlook the care of your AC system. Proper maintenance now ensures that it stays in peak condition and is ready for action when the temperatures rise again. Here’s a checklist from Milt’s Air of Amelia to help you prepare your AC system for winter:

  • Turn Off the AC System

The first step in preparing your AC system for winter is to turn it off. Leaving the AC unit running during colder months can strain the system and cause unnecessary wear and tear. Most systems have an external power switch near the condenser unit that should be turned off to prevent accidental activation.

  • Clean the Outdoor Unit

Over the summer, your outdoor unit can accumulate dirt, debris, and leaves. Clean the unit thoroughly by removing any build-up around it. Be sure to clear away any plants or shrubs within a two-foot radius to allow for proper air circulation and prevent potential damage during winter storms.

  • Inspect for Damage

Before winter hits, inspect your outdoor AC unit for any signs of damage. Look for bent fins, leaks, or cracks that could worsen during the colder months. If you spot any problems, call a professional to make necessary repairs before they turn into major issues.

  • Cover the Unit

While it’s not mandatory, covering your AC unit can protect it from harsh winter elements like snow, ice, and falling debris. Use a breathable cover to prevent moisture from being trapped inside, which could cause rust or mildew.

  1. Check the Thermostat

Make sure your thermostat is set to “heat” and functioning properly. This is also a great time to upgrade to a smart thermostat, which can help you save energy and control your home’s temperature more efficiently during the winter months.

  • Replace Air Filters

Dirty air filters reduce the efficiency of your HVAC system and can lead to higher energy bills. Replace your AC’s air filters at the start of winter, even if you won’t be using it. This will ensure that the system is clean and ready to go when spring arrives.

  • Check Ductwork

Your AC system shares ductwork with your heating system. Inspect the ducts for any cracks, gaps, or blockages that could reduce airflow and affect your home’s temperature control during winter. Sealing any leaks now will help your HVAC system run more efficiently.

  • Schedule a Professional Tune-Up for your AC System

Even if your AC seems to be working fine, a professional inspection can catch potential problems early. Milt’s Air of Amelia offers comprehensive tune-ups to ensure that your system is properly maintained and ready to tackle the next cooling season.

  • Inspect Insulation

Check the insulation around the refrigerant lines of your AC system. If the insulation is worn out or missing, replace it to protect the lines from freezing temperatures, which could cause damage.

  • Test the Heater

As part of your winter prep, don’t forget to test your heating system. Switch it on and let it run for a few minutes to make sure it’s working properly. If you notice any odd smells or strange noises, contact a professional for an inspection.

Preparing your AC system for winter helps extend its lifespan, improves energy efficiency, and ensures your home stays comfortable. By following this checklist, you’ll be able to safeguard your system against potential damage and avoid costly repairs in the future.
