"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!"

"We had a great experience with Ryan Hamilton Electric when they came to work on our building and in our apartment. We had discovered that the knob and tube wiring that we thought had been removed from our apartment was still present, and so we hired Ryan to remove the old type of wiring and bring our unit up to code. Ryan and his assistant Tim went above and beyond when it came to doing the work. Ryan explained very clearly to us exactly what the issues were with the knob and tube wiring and showed us exactly what had to be done to fix the problem. We had no surprises. While we were hiring Ryan to remove the old wiring, we also asked him about doing some other electrical work in our apartment. Ryan was happy to add on these further improvements and charge us only for the materials since we were already paying for the labor. Ryan listened to our desire for improved lighting and better outlets, and he presented solutions that would work for us and our kids. He found the perfect lighting fixtures for all the bedrooms and the bathroom, and he offered to improve lighting when it seemed necessary. The project took a few days; Ryan made sure we had the temporary lighting we would need in the evenings after he had completed work for the day. Ryan and Tim also cleaned up beautifully each afternoon when they were done with their work. Ryan and Tim didn't just do exemplary work. They were also warm, friendly, and affable, and a delight to have working in our apartment. We will actually miss having them around, but we were so impressed and delighted by their work that we plan to hire them again soon to improve the lighting in the kitchen and to install new outlets in the bedrooms. R. A. Hamilton Electric has my highest recommendation. I am a very happy and satisfied homeowner."

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."

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.
