Spring rolls in, bringing fresh air, longer days, and a big reminder — it’s time to check up on your air conditioning system. Without the right prep, the summer heat can turn your home into an unbearable sauna. A proven AC maintenance checklist for the summer keeps your cooling system strong, preventing breakdowns, costly repairs, and unnecessarily large energy bills.
Whether you need AC maintenance in Joliet, IL, or you’re just looking to boost your system’s efficiency, every part of your unit, including the air filter, thermostat, compressor, and drainage system, plays a role. Before the real heat kicks in, avoid potential problems with these crucial maintenance steps.
Check Your Air Filters
Air filters do more than just catch dust. They control airflow, filter out mold, and keep air pollution at bay for your home. A clogged filter forces your system to work harder, increasing energy consumption and wearing down components faster than normal. Dirty filters also mean poor indoor air quality, higher energy bills, and possible damage to your HVAC system that could require more extensive repairs.
If you have a smart thermostat, it may alert you when a filter change is due, but checking manually is often the best bet to identify problems early. Depending on usage, filters need to be replaced every one to three months. If you have pets, allergies, or recent home renovations, you’ll want to swap them out more often. Keeping filters clean extends the life of your unit, improves efficiency, and saves you money on air conditioning repair. If your air filters are in a hard-to-reach spot or you want to leave your checklist to the air conditioning pros, Comfort First Heating & Cooling is here to help!
Inspect Your Thermostat
Your thermostat is more than just a dial on your wall; it’s the brain behind your home’s temperature. If your settings are off, your air conditioning system could work harder than needed, burning electricity and shortening its lifespan. A programmable thermostat helps manage temperature fluctuations, preventing unnecessary wear and tear on your system. Getting it ready for the summer means checking the display and responsiveness and checking for any fluctuations. If you notice any of these issues, you may have a problem with electrical wiring or calibration.
If your AC cycles on and off frequently, thermostat placement could be the issue. Direct sunlight, vents, or drafts can throw off readings. A quick inspection keeps your HVAC maintenance in check, preventing unnecessary strain on your system. One of our experienced AC maintenance technicians can help adjust your thermostat placement to make sure it’s ready for the busy summer season.
Clean Around Your AC Unit
Spring brings pollen, debris, and dust that love to clog up your air conditioner’s outdoor unit. Leaves, dirt, and twigs collect around the condenser, blocking airflow, forcing your system to overwork, and driving your energy consumption through the roof. Without proper ventilation, you risk overheating, higher utility bills, and potential compressor failure that requires extensive repairs.
Cleaning around your outdoor unit removes debris from the fins, preventing corrosion and friction that reduces efficiency. While you’re at it, check for wear on electrical wiring, pipes, and insulation. An obstructed condenser won’t transfer heat properly, reducing cooling power when you need it most. Investing a few minutes in clearing debris helps your system breathe easy, reducing strain on moving parts.
Check the AC Unit Drain Line
If left unattended, moisture buildup in your AC’s drainage system can become a serious problem. A clogged drain line leads to water damage, mold growth, and system inefficiencies that ruin its lifespan. Algae, dirt, or debris could block the drainage line if your air conditioner struggles to cool your home. Standing water around the unit, musty smells, or an overflowing drain pan can also signal trouble.
A professional HVAC technician can inspect the drainage system for leaks, ensuring proper flow and avoiding future damage. A blocked drain doesn’t just affect cooling — it creates a breeding ground for mildew and bacteria. Stay ahead of potential problems with a simple drain check before summer heat waves roll in.
