As the last days of summer start to fade, the crisp, cozy season of fall is just around the corner. While you’re swapping out your summer wardrobe and prepping for pumpkin spice everything, don’t forget about your home’s most important comfort system: your HVAC unit.
Is your heating and cooling system ready to transition smoothly from cooling your home to keeping it warm as temperatures drop? Since 2009, Lenz Heating & Cooling, a veteran-owned, woman-owned, family-run business, has proudly served Des Moines with honest, expert care.
Here’s a quick late-summer checklist to get your HVAC system fall-ready, and why signing up for our HVAC Service Agreement is a smart move to keep your home comfortable all year long.
1. Change or Clean Your Air Filters
It sounds simple, but changing or cleaning your HVAC air filters is one of the easiest and most effective ways to keep your system running efficiently. Dirty filters restrict airflow, causing your furnace to work harder.
Tip: Check your filters every 30 days during heavy use seasons. If you haven’t replaced yours since spring, now’s the perfect time to swap it out.
2. Schedule a Furnace Tune-Up
Fall is the perfect time to switch from AC to heat. Regular maintenance helps prevent unexpected breakdowns, keeps your system running safely and efficiently, and prepares your home for those chilly Des Moines nights.
During a tune-up, our certified technicians will:
- Inspect and clean all key components
- Check thoroughly for gas leaks
- Test all safety controls for proper operation
- Ensure your system is running at peak efficiency
Scheduling a tune-up extends your furnace’s lifespan, giving you peace of mind as the cold season approaches.
3. Test Your Thermostat & Consider Upgrades
Your thermostat is the brain of your HVAC system. Before the temperatures drop, test your thermostat’s functionality and program settings. If your system feels sluggish to respond or if your energy bills are spiking, it might be time for an upgrade.
At Lenz, we offer smart thermostat installation that can help you control your home’s temperature remotely, which can save you money and boost comfort.
4. Inspect and Clean Your Outdoor HVAC Units
Your outdoor AC condenser has worked hard all summer. Now is the time to clear away any debris, leaves, or dirt around the unit to improve airflow. This simple step can help prevent damage and ensure your system switches smoothly between cooling and heating modes.
Need help? Our Lenz pros will handle the outdoor inspection and maintenance for you during our tune-up visits.
5. Seal Air Leaks and Check Insulation
Fall is the perfect season to inspect your home for air leaks around windows, doors, and ductwork. Sealing these leaks and ensuring your insulation is up to par keeps warm air inside and cold air out, lowering your heating costs.
We offer duct sealing services to improve your home’s energy efficiency and indoor air quality.
