Prepping Your HVAC for Summer: The Must-Do May Maintenance Checklist

Colorado summers don’t mess around. Before temperatures start climbing, it’s smart to get ahead with a few key HVAC maintenance steps. A little effort now means lower energy bills, cleaner indoor air, and fewer surprises when the heat rolls in. At Ultimate Heating & Cooling, we believe that taking charge early gives you the ultimate advantage.

Start Fresh with a New Air Filter

Think of your air filter as the unsung hero of your cooling system. It keeps airflow steady, energy bills lower, and indoor air healthier. Swapping out your filter every 30 days is one of the simplest and most effective ways to protect your system and your wallet.

Fresh filters improve airflow, reduce strain on the blower motor, and help trap allergens just when outdoor pollen counts start to spike. It’s a small habit that makes a significant impact when the summer heat settles in.

Fine-Tune Your Thermostat for Smarter Cooling

Before the season kicks into full gear, a quick thermostat check can save you serious money. The U.S. Department of Energy notes that upgrading to a smart thermostat can slash cooling costs by about 10% without sacrificing comfort.

Even with a traditional setup, adjusting the settings today avoids unnecessary strain on your system and helps you stay ahead of the summer heat.

Give Your Condenser Coils a Clean Slate

When dust, dirt, and grass clippings pile up on your outdoor condenser coils, your AC has to work harder to release heat. The Spruce points out that clogged coils force your system to run longer, lowering efficiency and raising energy costs.

Taking a few minutes to clear debris now helps your system cool faster, use less energy, and stay reliable through the hottest months.

Check That Your AC Unit Is Sitting Level

An uneven outdoor AC unit isn’t just a cosmetic issue — it can lead to serious operational problems. A condenser that isn’t level can cause excessive vibrations, refrigerant leaks, and premature compressor failure.

If your unit looks tilted, don’t wait. Getting it professionally re-leveled now can help protect your system’s lifespan and performance during the hottest months.

Book a Professional Tune-Up Before Trouble Starts

Just like you wouldn’t skip a car inspection before a road trip, your HVAC system deserves a full check before summer sets in. A preseason tune-up can catch issues like weak capacitors, clogged drain lines, or low refrigerant that might otherwise leave you sweating through a heat wave. Regular maintenance helps prevent unexpected breakdowns, enhances energy efficiency, and prolongs the lifespan of your system.
