- Closely follow the average True Cost Rate furnished on the Homeowners section of Home Advisor for labor costs - Show up on time and give up front estimates - Focus on service work and limited multi-day projects so my schedule remains fluid - Advocate on the customer's behalf shopping for best prices on quality materials and best practices to get jobs done to code at the best rate possible

"We had an issue with a Dry Well periodically backing up. Damian and the D Day Plumbing team were very professional and knowledgeable and provided an estimate with a couple different options and their related costs. They installed a new utility sink, sink pump, and needed piping and valves with tie ins to the main septic. They made improvement above and beyond the initial job breakdown, all the while staying within budget. I will certainly consider them again for any future work. Thank you Damian and the D Day Plumbing Team for a job very done!"

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.

"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.?

"they initially quoted $89 for AC diagnostics which is reasonable even though most companies charge nothing. Technician is very friendly and knowledgeable and walked me through the process. he checked the compressor outside and he suspected a leak. and then wanted to check the coil inside the blower. he detected a small leak with the electronic device. he mentioned coil may need replacement. After spending 10 mins in his truck to call the company he came back and said coil is not covered with warranty and quoted $5,400 to replace the coil and it is backordered for 6 weeks. 6 week will brings us to mid August so i told him i dont want to sign up for repair and wait 6 weeks. he then tried to sell me a maintenance plan which i declined. Then he said he will charge for the diagnostics which he spent total 30 mins including talking on the phone for warranty coverage. he said he did more than basic diagnostics which is $149. when he handed me the payment he added up initial $89 and $149 to pay $238 for 30 mins diagnostics. Total scam. i dont even know if they do any real work beyond the charging $238 for 30 mins diagnostics. probably they will hire a separate contractor to do the job and keep selling overpriced diagnostics and maintenance plans. They all you 10 times to sell you the initial diagnostics but after you pay $238 not even a single call to ask about experience. worst ever."

Thermostat installations and replacements FAQs

It's often worth replacing your old thermostat with a newer model that can enhance your home's comfort and energy efficiency. Upgrading to a programmable or smart thermostat can save you up to $200 per year on energy bills. Plus, smart thermostats offer convenient features like remote control and learning capabilities, making your home more comfortable and easier to manage.

Signs of a bad thermostat include your HVAC system not turning on when it's supposed to or failing to reach the desired temperature. If the thermostat's display is blank or not functioning properly, it could be malfunctioning. Another indicator is the HVAC system running continuously without shutting off or cycling on and off too frequently. You might also notice uneven temperatures throughout your home, with some rooms being too warm or too cold. These issues suggest that the thermostat is failing and may need repair or replacement to ensure your HVAC system operates efficiently.

A thermostat should last between 10 to 20 years, depending on its quality and how well it's maintained. Over time, dust, wiring issues, and general wear can affect its performance. Even if a thermostat is still functioning after 10 years, you might choose to replace it to take advantage of newer energy-saving technologies and smart home integrations. Upgrading to a modern thermostat can improve efficiency, offer more control over your home's climate, and potentially lower energy bills.

The number of thermostats you need depends on your home's size, layout, and heating and cooling zones. In a standard single-zone HVAC system, one thermostat controls the temperature for the entire home. However, larger homes or those with multiple floors might benefit from multiple thermostats linked to a multi-zone HVAC system. This setup can offer better comfort and energy efficiency: It lets you customize the temperature in different areas, so you're only heating or cooling the spaces you're using.

Replacing a thermostat typically takes a professional technician about one to two hours to complete. If you're swapping out an existing thermostat for a similar model with compatible wiring, the process can be done in less than an hour. However, installing a new thermostat that requires additional wiring, such as a smart thermostat, or moving the thermostat to a new location can extend the time to two hours or more. Complex installations may also involve cutting into drywall or integrating with other home systems, which can add to the duration.

There are a few things that can cause your home thermostat to fail. The most simple one is age and cleanliness. Dirt, grease, dust, and other small particles can clog sensors and cause malfunctions in readings. You may also have a failing power supply and loose connections, and the simplest cause is that it isn't installed in the right place in your home so it can't properly sense air temperature. Repairing a thermostat costs around $210.
