At MillTown Plumbing, Heating, AC, Drain Cleaning & Electrical, we know the value of prompt, professional and reliable services and look forward to serving your needs in the Merrimack Valley. We're a same day/next day service company offering quality work and unbeatable service.

"I used to like them. Use them for my big install of backup basement sump pump. This time, I was out of the country, my rental property in MA needs a toilet fix. It was a standard water tank leak and we need to replace the inside mechanism. Milltown came and said 'rebulid the toilet', my wife authorize them to do it as I was not reachable at the time their plumber was at the rental property. They were in and out according to my tenant for at most 45 min, rebuilding two toilet tank and fixed the leak. The bill came to be 1200, $600 a toilet. One line item on the receipt is $470 for the kit they use to replace the plastic mechanism inside the water tank. I casually google the kit, I can get a universal sup kit for the toilet to replace that for $20. I called them, manager came on gave me that talk - we did hundreds of toilet leak and we average all of them to come up with the cost for that line item, which includes (a) parts (b) labor (c) our service guarantee for a prompt and reliable service Say they charge $200 /hr labor, 1 hr for two toilet is $100 labor for 1 toilet (remember, the plumber was there like 30-45 min rebuilding the two toilet). Say total parts are $100 (with markup), we are talking about $200 for fixing the leak of 1 toilet. They charged almost $600 for one toilet. You can do that math. I expect some up charge, but I am not paying $300 just for getting prompt reliable service. I turned around and asked for a few reliable plumber quote from Thumbstack with great reviews, most can do the job for $200 labor and I can get them the universal kit they will be able to come on the same day. So maybe if you want Milltown to do bigger job, that is ok. For smaller job, it does not worth it. Replacing the toilet flush mechanism is really not rocket science in plumbing. If I am not thousands of miles away, I would have done it myself after watching some Youtube video. I am willing to pay up charge for the service, but this is really above and beyond the normal up charge range, $1200 for a 30 min job replacing the toilet flushing mechanism in the water tank!!"

We are experts at providing air conditioning solutions for older homes, oil/gas to heat pump conversions, and are Mass Save certified heat pump contractors. We’ve built a reputation for superior quality, through years of putting the customer first and getting the job done right the first time. As local residents, our family and expertly trained team of technicians think of our customers as neighbors; our goal is to maintain our reputation as a quality organization, continuing to offer superior heating and cooling services in the Boston area and ensuring that you can be proud of our work and products for years to come.

"Diagnosis and repair were straightforward and the talented Mike, who has done other great work for us on our ACs, had a replacement pump in his truck. Swapped over in under an hour. Cost of the repair was quite high, mainly due to very high price they charged for the pump. A Taco pump that I could buy for $175 was priced on this repair at more than $500. I get that it was an urgent situation and I’m happy to pay reasonably for the response but that mark-up bothered me. I called the office, had a long talk with the owner; sadly, she offered no consideration at all. Yes, it’s hard to find and keep skilled techs, but now seems that most HVAC firms have a business model like a car dealer’s service dept, far more corporate, less flexible or customer-considerate."

All that for just the cost of a day's labor!"

FAQs for central humidifier installation and replacement projects in Boston, MA

Aim for indoor humidity between 30% and 50%, with the sweet spot around 45%. That range keeps mold, dust mites, and musty odors in check while protecting drywall and woodwork. Staying in the zone also helps your HVAC system run more efficiently and supports healthier air for you and your family year-round, during hot summers and cold winter months.

With routine filter changes and coil cleanings, most whole-house units run for eight to 15 years. Heavy use, poor air quality, or bargain-bin equipment can shorten that span, while a well-maintained, high-quality model often makes it to the upper end of the range. Ask your installer about recommended service intervals to get the most mileage from your investment.

It depends on your climate. Homes in cold, dry regions can often shut the dehumidifier off once winter sets in. If you live in a warm, humid area—or your house tends to trap moisture—you may need to keep it running year-round. Use a simple hygrometer: if readings stay below 50%, give the unit a rest. Just remember to restart it when humidity climbs again to avoid mold and condensation.

Dry air feels cooler, so your AC doesn’t have to work as hard. By stripping out excess moisture, the dehumidifier lets you raise the thermostat a few degrees without losing comfort. A shorter AC runtime reduces electricity use and can shave a noticeable amount off your summer power bill. Energy-efficient models further enhance those savings.

If your home is under about 2,000 square feet, a well-placed portable unit can handle the load. Just remember they’re less efficient and need hands-on upkeep—think emptying tanks and cleaning filters. If you prefer set-and-forget convenience or plan to expand your living space, a whole-house model still offers better long-term comfort and lower energy use per square foot.
