Is Your Thermostat the Problem? How to Tell When It’s Time for an Upgrade

Sometimes what seems like an AC issue is actually a thermostat problem — and during the peak of summer in Villa Park, that can lead to a lot of frustration and wasted energy. At Planz Heating & Air Conditioning, we regularly help homeowners troubleshoot cooling problems that turn out to be related to old, faulty, or poorly placed thermostats.

If your system constantly cycles on and off, struggles to reach the set temperature, or isn’t responding at all, your thermostat could be the culprit. Older thermostats can become inaccurate over time, causing the system to run longer than needed or shut off too early. Bad wiring or improper installation can also cause inconsistent performance. We also see problems when thermostats are installed near windows or heat-producing appliances, which affects their ability to read indoor temperatures correctly.

Upgrading to a smart or programmable thermostat can help reduce cooling costs and improve comfort by giving you precise control over your home’s temperature — even when you’re not home. If you’ve been searching “thermostat not working Villa Park” or “smart thermostat installation near me,” we can help you choose the right model and ensure it’s installed properly.
