Trusted since 1946, Schraer Air Experts offers top-notch heating, cooling, air quality and hot water services in Warren, Montgomery, St Charles and Lincoln County MO.

"I cannot say enough wonderful things about this amazing company! My daughter and I had been without a furnace for over 6 years. We used space heaters in the bedrooms, bathroom and kitchen, but the rest of the house stayed cold. Along with that, I had a constant fear of an electrical fire resulting from the units, because last year a young mother and her baby died in a house fire down the street from us, most likely caused from a space heater. When Schraer came to our home that offered to install gas furnace free off charge that was just sitting in their shop! We are truly Blessed and Grateful for their kindness and generosity! There are good people out there in the world, and the owners and employees of Schraer Heating and Cooling are some of best!"

"Clint started off strong as a handyman. His workmanship was excellent, his rates were fair, and he was pleasant to work with. Unfortunately, there began to be recurring issues with schedule management and timely communication, which negatively impacted my projects. A miscommunication ultimately led to offense being taken, and he abruptly discontinued work via text without notice to my surprise. Disappointed though I am, I?m thankful for the work he was able to do and wish him all the best as I start the process again to secure another handyman for my remaining items and to have on hand for regular maintenance in the long term.

FAQs for thermostat installation and replacement projects in Wentzville, MO

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.
