"As soon as I hit send on my Angie list query Rob Wotton called me and came over the next morning for a detailed discussion. I got a detailed quote soon after that which was lower and better than the quote from my oil company. Rob also changed his schedule and replaced the oil boiler and water heater a day later as cold showers were getting old! All good!"

Labelled all pipes to outside, installed new thermostat and on and on. I can not say enough about how satisfied I am with the job. Also my house is finally getting the cold air to top floor! Extremely Happy!"

"I was stood up by another plumbing company with $1300.00 worth of equipment ready for install . I contacted Home Advisor, and received a call from Doug Anderson, Plumbing and Heating (781 228- 1561) within 15 minutes. He came over later on that evening to evaluate my dilemma. Great service! We scheduled an appointment for the work to begin, to rectify my issue's, within a couple of days. I would highly recommend him. Working with this company was a great experience. They gave me an estimate without any hassle and performed the work as expected and at the estimated amount. Doug Anderson answered my questions thoroughly and professionally. I recommend this company to others. "Thank you for your prompt attention to my plumbing problem."

"Scott did a fantastic job. Inducer motor was not working in my carrier infinity furnace. He fixed it without me needing to replace the expensive motor. He is good in communication and explained my questions patiently and effectively."

"I'm a deep value oriented consumer and this guy is one of the best contractors I've come across for the money. Why would you want to pay for the administrative and marketing costs which comes with the fees charged by the big box guys. D-Day is a true professional and a master craftsman at his work. I've hired him to replace a water heater, install a dishwasher and washing machine, as well as miscellaneous plumbing repairs with exemplary results. I wouldn't even consider looking elsewhere."

"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. "

"Bob helped me out to replace old ducting for a kitchen hood vent from a smaller size to a bigger one to prepare for new larger kitchen hood that I will be installing. He went above and beyond what I was was hoping for the project including adding a thermal break, additional insulation and damper to the vent that I did not think of. He was great to work with and had great recommendations for future projects at home. I will totally work with him again in the future."

FAQs for thermostat installation and replacement projects in Littleton, 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.
