"Ken is a great guy. I already diagnosed the issue before calling him, so he gave me the quote over the call and his prices were great. He brought the part and installed very next day. I am really happy with the service. He was very professional, polite, and a humble guy. Will highly recommend him."

"We had a plumber before who charged $300 and did not fix a leak. These men immediately saw the problem and fixed it. They also installed 2 toilets very efficiently."

"My central air system went down in the middle of a heat wave and virtually every HVAC repair service that I called told me that they weren t taking new clients and couldn t help me. I contacted Chris through home advisor and he agreed to help me out. He promptly came to my house, identified my problem, and ordered parts. When the parts arrived he immediately came back and installed them and I was up and running. Chris identified and fixed my problem and the entire process took only 2 days. On top of that, the price was more than reasonable and Chris is a super nice guy. I highly recommend Chris because he is a skilled and professional technician."

"I recently had a brand new HVAC system installed for both heating and cooling, and I couldn’t be happier with the experience. The team at Comfort Professor was extremely professional from start to finish. They worked efficiently, paid attention to every detail, and left everything spotless when the job was done. The cleanup was perfect, which I really appreciated. Highly recommend them if you’re looking for quality work and a smooth, hassle-free installation!"

FAQs for thermostat installation and replacement projects in Watertown, MA

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.
