AC Maintenance Myths That Could Cost Chicagoland Homeowners This Summer

There are a lot of myths surrounding air conditioner maintenance — and believing the wrong ones could cost you comfort, money, or even your entire system. At Planz Heating & Air Conditioning, we often talk with Chicagoland homeowners who think they can skip tune-ups, wait until the AC breaks, or rely on a filter change to keep things running smoothly. In reality, that approach can lead to higher energy bills and expensive repairs, especially in the middle of a hot July.

One of the biggest myths is that if your AC is cooling, you don’t need service. But internal wear and hidden issues like dirty coils, weak airflow, and low refrigerant often go unnoticed until they cause real damage. Another common myth is that replacing your filter is enough. While filters are important, they only address airflow — not the dozens of other components that need attention. And finally, many homeowners assume their AC will last 20+ years with no problems. In the Chicago suburbs, where systems run hard in both summer and winter, most units need replacement after 12 to 15 years — especially without proper care.

If you’ve been putting off service or believe your system is “fine for now,” don’t wait until it stops working on a 90-degree day. Search “mid-summer AC maintenance Chicagoland” or “Villa Park HVAC checkup” and schedule an appointment with Planz. We provide full-service inspections, tune-ups, and repairs throughout Villa Park, Oak Brook, and the west suburban Chicago area.

Stay ahead of the heat. Mid-July is the perfect time to give your AC the attention it needs to keep running efficiently for the rest of the season.
