As winter fades and warmer weather starts creeping in, it’s the perfect time to think about your home’s HVAC system. After months of hard work keeping you warm, your system deserves a little TLC before it switches gears to keep you cool. For homeowners across Illinois — especially in areas like Lake in the Hills — spring HVAC maintenance isn’t just a good idea, it’s essential for comfort and energy savings. Here’s a practical checklist to get your system ready for the season ahead.

1. Change Your Air Filter
This is one of the easiest and most important steps. Your air filter has been working overtime all winter, collecting dust, pet dander, and who knows what else. A clean filter improves airflow, helps your system run more efficiently, and keeps your indoor air cleaner. Ideally, you should replace your filter every one to three months, depending on your household.
2. Check and Clean Your Outdoor Unit
Once the snow melts, take a quick walk outside and inspect your outdoor HVAC unit. Leaves, dirt, and debris can pile up around it, blocking airflow and making the system work harder than necessary. Use a garden hose to gently rinse off any dirt and clear away anything that’s piled up nearby.
3. Test Your Thermostat
Before the first real warm day hits, switch your thermostat over to cooling mode and make sure it’s working correctly. If you’re still using an older thermostat, consider upgrading to a smart thermostat for better control and potential energy savings.
4. Schedule Professional HVAC Maintenance
This is the most important step. Spring is the ideal time to bring in a pro to give your system a full tune-up. Our expert technicians at 24Hr Home Comfort Services Inc. will inspect your entire system, check refrigerant levels, clean coils, test electrical components, and more. Catching small issues now can prevent costly breakdowns during the summer heat.
5. Don’t Forget Your Ductwork
Your ductwork plays a huge role in your HVAC system’s performance, yet it’s often overlooked. Leaks, dust buildup, and blockages can reduce efficiency and lower indoor air quality. As part of your spring checklist, consider a professional duct cleaning to remove accumulated dust and debris.
6. Enroll in Our Security Blanket Maintenance Plan
Want to make HVAC maintenance even easier? Enrolling in our Security Blanket Maintenance Plan means you’ll never have to worry about forgetting regular tune-ups. With this plan, you’ll get priority service, discounts on repairs, and the peace of mind of knowing your system is always in top shape.
7. Consider an Air Quality Upgrade
Spring is allergy season, and your HVAC system can either help or hurt your indoor air quality. Upgrading your system with air purifiers, UV lights, or better filters can make a noticeable difference in how fresh and clean your air feels.
