Customers say: Quick response

"We have used this company for both rental and owner-occupied properties. They replaced the roof, gutters, and worked with the company to make sure that our awnings and other items were replaced. They also worked very well with our insurance company and we had no problems at all. Jacob made everything so easy that if we ever need anything else done and they can do it, they have the job."

"I have had nothing but perfect experiences with Missouri Furnace and Air Conditioning. They installed my boiler heater furnace in 2006 and my air conditioning unit in 2009, and I have used them ever since for the maintenance and service on both. Their customer service personnel are so nice and they get your service call scheduled very promptly. If there is any sort of emergency they will arrange to get a technician to your house the same day if at all possible. The knowledge and expertise of the service technicians is top of the line, and the technicians are always willing to fully explain the work that they are doing in terms that I can understand. Missouri Furnace & Air Conditioning is a truly exceptional company and I would never trust the care of my heating and cooling systems to anyone else. I give them my highest recommendation!"

"The service was excellent! They arrived to pick up the vehicle a day earlier which was great. They delivered the vehicle right to my daughter's door and found a side street to unload. The service was delivered within the time frame given. All of my questions were answered via phone or email and the paperwork was seamless and the price was very reasonable."

FAQs for thermostat installation and replacement projects in Florissant, 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.
