" 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"

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.
