Customers say: Terrific value

"In preparation for a remodeling job, I needed ductwork raised in my basement. Minutes after HomeAdvisor called me to see if I needed another bid on my project, Jay called to say he was nearby and asked if he could he come over. He was there in 10 minutes, gave me a bid that was far below the two I had previously received, had a crew over in less than an hour, and finished the work before mid-afternoon. He and his crew were polite, competent, and efficient. I would not hesitate to use them again."

" The sales representative I spoke with, misrepresented the services in order to secure a service call. She told me the truck would arrive fully equipped to handle diagnostics, battery work, and related issues to fully diagnose a generator, which turned out not to be true. The technicians who came out were polite and professional, and this review is not directed at them in any way.. This ended up wasting a significant amount of my time and money"

"Metro West Mini Splits recently installed 6 mini splits in February 2025 to our new home in Marlborough, MA. Alan, Jamie, and their team were so kind, respectful, knowledgeable, timely, communicative, and easy to work with. We could not be happier with the final product! Metro West Mini Splits was also very reasonably priced, and they made the Mass Save rebate process a breeze. 100% would recommend to anyone needing heating or cooling services!"

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.
