"I needed a kitchen faucet replaced. I had the new faucet. When I called Milltown, they said they couldnt give me an estimate over the phone, and had to send someone first to see if they could do the job with my faucet. It would cost $85 to do this, whether or not I hired them. The repairman came at the appointed time, was polite and pleasant, and told me it would cost $419, and this was a standard fee. So, it turns out I could have been given a firm estimate over the phone, and had I been, I would have said no thank you and gone elsewhere. It took less than an hour for the faucet to be replaced. Neurosurgery costs less money per hour. I told this to the rep from Milltown who called me a few days later to see how it went. I told them how shocked and disappointed I was with the cost. I said that without a cost adjustment, I would write an appropriate review. It's been a month and no one got back to me. A compete ripoff! Neurosurgery costs less per hour! UPDATE: I was contacted a few weeks ago by the customer service rep who was extremely responsive and asked me what I thought was a fair price for the job, which I gave him, and he honored my request to refund me the difference. Thank you."

"Mr. Castillo was excellent. Prompt, evaluated the issue & immediately went out to get the necessary supplies needed for a replacement installation of a 30 year old wall heater. Competitive pricing. Would hire again & highly recommend."

"The young technicians who came to my home to installed the new thermostat and move it to another wall in my home were polite and conducted themselves professionally in my home and cleaned after themselves. I very appreciated Uri suggestion when he recommended to me another alternative at the initial visit and gave me a few quotes to choose from. So I'm very happy with ER service and I would rehired these two individuals back to my home. I will definitely recommend ER to other people in my life."

"Quick contact and scheduling of first visit. Competitive quote and the work was done professionally. Follow-up visit to address a minor annoyance was also very prompt. Well prepared to work with different circumstances and contingencies on a roof-top heat pump replacement which required crane to access. I would strongly recommend."

"A godsend for those annoying jobs that are too random for a general contractor but too big to DIY (or you just aren't getting around to it!!). Joseph's team can solve a lot of problems. Not every problem, but I have yet to think of one they can't solve."

"I had gotten very busy and had to reschedule once or twice- they were very flexible and accommodating. Also, they got very busy, they were trying to finish up some outside jobs and The owner explained that it was going to be at least 3 weeks. He let me know right a way if that didn't work for me, they could refund me the cost asap. I appreciated his honesty and his desire not to tie up my money. They came to look at the job, 3-4 weeks after our phone conversation. There were 2 guys- they were thorough as they looked and took some measurements. They were also on the phone with the owner. I told them what I thought and what I was trying to figure out. I was told they would have to get back to me with the estimate and other particulars, and that was fine. My situation changed and I couldn't actually put in the time to deal with such a job regardless of what they told me. But the owner told me the job was bigger than I thought- they could do some repairs, but it wouldn't be sufficient with the amount of damage- and it would definitely take more that 8 hours, probably 3 weeks. I didn't have that kind of time or money, and asked for a refund. I had to go through Angie's list Refund Process, but it was okay and it took a while, but it was done. A week or two later the owner called to see if I got my refund and just to follow up and check in. I really appreciated his follow up. He emphasized that he wanted me to be satisfied either way. That's what I call GREAT Business."

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.
