The Maynard Man Shares the Steps of AC Maintenance

Your air conditioner works hard to keep you cool—but are you giving it the attention it deserves? Without regular maintenance, even the best AC systems can lose efficiency, struggle to keep up, or break down altogether. Thankfully, taking care of your cooling system doesn’t have to be complicated. The Maynard Man is here to walk you through the essential steps of AC maintenance, whether you’re looking to DIY a few basics or understand what a pro will do during a seasonal tune-up. From filters and coils to drain lines and thermostats, every step plays a role in keeping your system efficient and reliable. Let’s break down exactly what your AC needs to stay in peak condition all summer long.

Step 1 – Replace or Clean the Air Filter

Your air filter is one of the most important parts of your air conditioning system—and one of the easiest to maintain. It traps dust, dirt, and airborne particles before they can enter your system and affect your indoor air quality. But over time, that filter gets clogged, which restricts airflow and forces your AC to work harder than it should. To keep your system running efficiently, check the filter monthly and replace or clean it every 1 to 3 months, depending on the type of filter and usage. Homes with pets or allergy sufferers may need more frequent changes. A clean filter improves airflow, reduces energy use, and helps extend the life of your system.

Step 2 – Clean the Outdoor Condenser Unit

Your AC’s outdoor condenser unit does a lot of heavy lifting, and it needs a clear path to breathe. Over time, leaves, grass clippings, dirt, and debris can build up around the unit, reducing airflow and forcing the system to work harder. This not only affects performance but also puts unnecessary strain on the compressor. Start by turning off power to the unit, then gently remove debris from the exterior. Use a garden hose (not a pressure washer) to rinse the coils from the outside in, and make sure there’s at least two feet of clearance around the unit. Keeping it clean ensures better efficiency and extends the life of your equipment.

Step 3 – Inspect Thermostat Settings

Your thermostat is the command center of your cooling system, and keeping it properly set can improve both comfort and efficiency. Start by making sure it’s set to “cool” and the temperature is where you want it. If your system isn’t responding the way it should, it could be a sign the thermostat needs new batteries or a calibration check. This is also a great time to consider upgrading to a programmable or smart thermostat. These models allow you to create cooling schedules based on when you’re home, asleep, or away—helping you save energy without sacrificing comfort. Even small adjustments in thermostat settings can make a big difference on your energy bill.

Step 4 – Check and Clear Drain Lines

Your air conditioner doesn’t just cool the air—it also removes humidity. That moisture is collected and drained away through the condensate drain line. Over time, algae, mold, and debris can build up inside the line, leading to blockages that cause water to back up into your system or home. To prevent clogs, inspect the drain line regularly and look for standing water or musty odors near the unit. You can use a wet/dry vacuum or a gentle flush with vinegar or warm water to help clear buildup. Keeping this line clean ensures your AC runs smoothly and helps prevent costly water damage or shutdowns.

Step 5 – Check Electrical Connections and Controls

Your AC system relies on a series of electrical components to power the blower, compressor, and other key parts. Over time, wires can loosen or corrode, and connections can wear down—especially with heavy summer use. Faulty electrical components not only affect performance but can also become safety hazards. While homeowners should leave in-depth electrical inspections to the pros, you can still do a basic visual check. If you notice frayed wires, burn marks, or a lingering electrical smell near the unit, turn off the system and call a technician. During a professional tune-up, the Maynard Man checks all wiring, relays, and capacitors to ensure your AC is safe and fully operational.

Step 6 – Inspect System Performance

Once your system is cleaned, cleared, and reconnected, it’s time to run it and see how it performs. Set your thermostat to cool and let the AC run for a full cycle. Check the airflow from each vent—air should feel cool and consistent throughout your home. Uneven cooling, weak airflow, or extended run times can all point to underlying issues. While it’s running, listen closely for any unusual noises like rattling, buzzing, or hissing. You should also keep an eye out for warm spots in the home, a system that struggles to shut off, or humidity that lingers longer than usual. If anything feels off, it’s time to call in a pro for a deeper inspection.
