"Hello Everyone! I'd like to give Milltown a shout out for installing our new HTP Combo unit. I'd like to especially thank Garret, Brandon, and Kat for pulling the whole thing together and making the installation as seamless as possible. Also, shout out to HTP for replacing a defective unit. They stood up and did the right thing when they didn't have to. Milltown went above and beyond what a plumbing company would typically do. When our combo unit failed, we lost heat and hot water. Milltown was able to hook up a temporary hot water tank so my family had access to heated water for showering, dishes, etc. Everyone I spoke to were genuinely concerned and could not have been more professional in their workmanship, cleanliness, and finished product. I am very pleased with everything from start to finish."

"I needed 2 backflow preventers replaced , a water heater repaired and a to0ilet repaired. I had a quote from a very famous local plumbing/heating company for $4000! I called Doug for a second opinion and he came in at HALF the price!! and that was AFTER I showed him the first quote! He didn't seem surprised at all about the first quote. Not only was he half the price but he pointed out that my 6 year warranty on my water heater had 6 months left and said I could get a new one thru that warranty for $100!!! He took care of going thru the company getting me the new heater. He completed the job in a few hours. I will NEVER call another plumber again! My recommendation is to run, not walk, to get Doug for your needs. On top of that he is so very nice. I would give 10 stars if I could."

"Amaury is fantastic! We originally hired him in fall of 2020 to replace our outdated electrical heat baseboards before selling our condo. He is now our go-to electrician for all things electrical in our new home. Heâ s offers very competitive pricing, is extremely prompt and always helpful. 10/10 recommend!"

"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."

"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"."

"It took too long for Angi to match me with a service provider. I tried and requested several dates, waited for someone to pick up the job, and when no one did I was assigned a later and later date each time. It was weeks out and the trampoline was sitting in my driveway over a week already. I only rated this person bc I had to. I never met him or spoke with him."

FAQs for thermostat installation and replacement projects in North Chelmsford, 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.
