"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."

"The technician/repair man was informative, professional, and a good troubleshooter. I appreciate that he explained what he was doing and how he arrived at the conclusion that he did. He even gave me advice on what to look for when I replace my thermostat."

"Kevin honestly saved our Christmas. Another company had been out and said we needed a new part in order to get our furnace going again. The problem was that the appliance stores were closed for the next 4 days for the holidays. Kevin came and determined it wasn’t a problem with our furnace but rather our thermostat. He then went out to buy a replacement and installed it himself. I wanted to cry happy tears but kept it together for the sake of not making it awkward, haha. On top of that, he was friendly, patient with my 1 year old who was obsessed with him, and so affordable that I had to double check he charged us enough. I’m a customer for life."

FAQs for thermostat installation and replacement projects in Maryland Heights, 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.
