"James was prompt, hardworking, diligent and very reasonably priced. He installed a chandelier in our 18 foot family room and did a great job! I would absolutely use him again in the future. I think we found ourselves a good, reliable electrician."

"Carlos called me the next morning, and sent 2 technicians over. At several points during their stay, they were video call with Carlos discussing the situation. They found a solution and explained to me carefully what they were doing, what the next step is if this step would prove inefficient. Their price was reasonable. Carlos called me several days later to check on the system, and gave me additional advice. I would hire them again."

"I interviewed 3 other HVAC companies for an AC issue. They were the most professional and explained exactly what was needed and why. They explained the different options to meet my goals. They were timely, clean and went above and beyond the agreed job parameters by flagging a problem with the humidifier. I would highly recommend ThermoPro."

"The team at Aire Serv of Lake Forest-Gurnee is absolutely amazing. They came in after a couple of other companies and found the real issue with my furnace and worked really hard to get it replaced as quickly as possible! I could not recommend them enough! The whole team from the dispatcher to the technicians that did the install are the best!!!"

FAQs for thermostat installation and replacement projects in Gurnee, IL

Smart thermostats may be worth it for many homeowners. They come with various features, including voice control and smartphone apps. Vacation mode can help lower energy usage when you’re out of town for an extended period. Alert warnings let you know about major spikes or drops in temperature. Smartphone apps can track energy usage, and smart thermostats can learn your routine over time to adjust your temperature and reduce wasted energy consumption automatically.

You typically do not need more than one smart thermostat. While it’s common to see multiple mechanical thermostats throughout a large home, multiple smart thermostats may try to override each other. This can lead to problems with the HVAC system. Ensure the unit you buy has the option for dual- or multi-zoned systems to avoid compatibility issues.

Installing a programmable or smart thermostat may save you $180 per year in utility costs. A big part of this comes from a smart thermostat’s ability to learn and adapt to your regular routines. With smartphone apps or web-based interfaces, you also have the option to control your thermostat when you’re not home.
