HVAC Repair & Service in Marion, IL FAQs

Can upgrading my thermostat actually lower my energy bill?

Yes, upgrading your thermostat can lower your energy bill—especially if you switch to a programmable or smart thermostat. These advanced thermostats allow you to automatically adjust your home's temperature based on your schedule, so your system doesn’t waste energy when no one’s home. A smart thermostat learns your habits and can even optimize energy use based on weather conditions. Some models give real-time energy reports to help you make cost-saving decisions. By reducing unnecessary heating and cooling, homeowners can see energy savings of 10–20% or more annually. In short, modern thermostats boost efficiency, reduce wear on your HVAC system, and help cut utility costs—making them a smart upgrade for comfort and savings.

How do pets impact my home’s heating and cooling efficiency?

Pets can impact your home’s heating and cooling efficiency more than you might think. Pet hair and dander can clog air filters faster, restricting airflow and making your HVAC system work harder. This reduces efficiency and can raise energy bills. Pets also tend to bring in more dust and allergens, affecting indoor air quality and potentially straining your system. If pets frequently go in and out, they may let hot or cold air escape, forcing your HVAC to compensate. Regularly changing filters, scheduling routine maintenance, and sealing doors can help maintain efficiency. In homes with pets, it’s especially important to keep your HVAC system clean and well-maintained for optimal performance and comfort.

Does running ceiling fans really help my HVAC system work better?

Yes, running ceiling fans can help your HVAC system work better by improving air circulation and making your home feel more comfortable at higher thermostat settings. In the summer, ceiling fans create a wind-chill effect, allowing you to set your AC 2–4 degrees higher without sacrificing comfort. In winter, reversing the fan direction helps push warm air down, reducing the workload on your heating system. This means your HVAC doesn’t have to run as long or as often, which can increase efficiency and lower energy bills. Just remember: fans cool people, not rooms, so turn them off when you leave. Used correctly, ceiling fans are a simple way to boost HVAC performance and save money.

Charlie himself (and his son) came and saw to our problem. It turned out to be sort of a non-issue, but they still didn't charge us an arm and a leg for coming to check on it (and cleaned a few things out in our A/C system which was nice). They also could get to us much sooner (like, a week earlier) than other local companies. Will be calling them again!

Set a same day appointment. Showed up on time (even sent a text with a pic of the tech coming to service us). Fantastic service. Took the time to call me and explain everything that he'd already discussed with my wife. Very friendly and reasonably priced as well. Definitely recommending them to anyone I know! Thank you! **Had our yearly follow up(9/5/25) and Daniel handled our service again and was just as awesome this time as the last. Showed up early, was very efficient and friendly as ever. We appreciate you Daniel AND Charlie's!
