Zupan Heating & Cooling | Certified HVAC Repair in Des Moines, IA

For aging systems common in our area, we recommend a professional efficiency evaluation. Our technicians will assess your unit's performance, refrigerant levels, and component wear. Often, a precise tune-up can restore significant efficiency and extend its life. If a replacement is the most cost-effective long-term solution, we provide clear options tailored to Des Moines homes, focusing on reliability and energy savings for our climate.

In the Des Moines area, with our varying seasons and potential for dust and pollen, we generally recommend checking your filter monthly and replacing standard 1-inch filters every 1-3 months. Homes with pets, allergies, or more dust may need changes monthly. A clogged filter is a top cause of system strain and poor airflow. During our seasonal maintenance visits, we always check and can remind you of the optimal schedule for your home.

Watch for signs like rising energy bills, reduced airflow from vents, the system cycling on and off frequently, or unusual dust in your home. A severely clogged filter forces your system to work much harder, which can lead to overheating, frozen coils, or premature component failure. If you notice these issues, it's best to turn the system off, replace the filter, and call us for a check-up to ensure no damage was done to your Des Moines home's HVAC equipment.
