"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."

"From the first email to the last nail, Bob was the best. It’s rare to find someone who cares so much about the work he does—Bob does. He not only took the time to do things right, he took the time to go over everything with us in detail. Bob replaced a handful of mahogany boards on our deck, installed two new light fixtures—bedroom and front porch— built a fence gate, repaired a broken stair baluster, installed a ceiling fan, replaced a rotted board on our shed, and gave us lots of advice and idea for future projects. The work took almost four days. Bob texted every morning to let us know when he’d arrive. He cleaned up as he went and at the end of each day. The project came to around $4,500. It was money well spent."

"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."

"Installed a new A/C system, replacing the old non functioning units. The job was done on time with no surprises. Customer service to set up the appointment was easy and a young man named Josh executed the job with no issue. He seemed to be very knowledgeable on his profession, showed up as expected and left nothing behind but a properly functioning system. Would absolutely recommend this company for their services."

"The install crews from weathervane were mostly well informed and efficient. The mini/split system seems to be working well. My only---heads-up with not just this company, but just about everyone now a days is that I do not text. (Dexterity issue) So I was not always "in the loop"."

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.
