"The provider came out to prepare my toilet because it was leaking in the basement. Overall, I thought the process went well. He could not get the valve beside the toilet to turn off so he turned off my main water valve to the house. He only opened up the faucet upstairs unit Downstairs unit was not open and my water heater, which is electric was not turned off now I m getting an alarm on my water heater saying it has been compromise. I consulted a plumber and was told that the water heater should ve been turned off because it s electric and he should ve bled the water heater After he turned the water back on. So the alarm is still on my water heater."

Since 1979, we've provided the highest quality protection against plumbing, heating, cooling, electrical and drain problems for residential and commercial and properties in the Merrimack Valley. At MillTown Plumbing, Heating, Cooling and Electrical, we're a family owned and operated business. We know the value of fast service, from a professional and reliable team. Give us a call today at (617) 725-2674! We look forward to serving you. Our Commitment to You Our fully licensed and bonded technicians are committed to answering your questions directly and honestly and solving your plumbing problems to your satisfaction. We'll even suggest the most cost effective solutions. Our plumbers are courteous, friendly and will always leave your home clean and work-sites tidy.

"Young man who came to do the job told us that they sent him to 3 wrong houses before they found ours. He proceeded to unclog the drain in the basement using the mechanical drain. Took him maybe an hour to clear it and also ran our sinks and toilets to make sure we wouldn?t have another problem. The young man left our house, however proceeded to sit in his running van, parked in my parking spot. I had no issues with this service until I saw the bill. $1000 to snake a drain for an hour? When we inquired about the bill they told us that their rate is 300$ an hour and that the job took 3 hours. In my opinion, if it takes you 3 hours to snake a drain, then someone should be fired or retrained at their job. My assumption is that their scheme involved sending this young man to multiple wrong houses and him sitting in my driveway for a prolong period of time, so that they could charge us for 3 hours of ?work.?

FAQs for thermostat installation and replacement projects in Andover, 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.
