We are a multi-generational family-owned and operated business based out of the western suburbs of Chicago. We are in business for one simple reason: To comfort families. We provide a holistic approach in that we treat our customers like people and not just a number. We have turned the traditional service model upside down and instead of rushing our Technicians to maximize calls each day, we provide the flexibility to ensure they take their time with our customers to ensure quality visit every time. That is the Leslie difference. We think our satisfaction ratings substantiate this and we are honored to be of service.

"We had an excellent experience with Leslie Heating and Cooling, and I can't say enough good things about the service we received! Our comfort consultant, Jeremy M., was great to work with. From the moment he arrived, he was incredibly friendly, professional, and willing to go the extra mile to make sure we found the best solution for our home and budget. He patiently answered all of our questions and took the time to thoroughly explain the options, making sure we felt comfortable every step of the way. It’s rare to find someone so dedicated to customer service, and Jeremy truly made a difference. I highly recommend Leslie Heating and Cooling. "

FAQs for thermostat installation and replacement projects in Chicago, 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.
