The company takes pride in the title as a Diamond Elite Contractor with Mitsubishi Electric and being selected into the National Grid VPI Program. Finally, a company that picks up the phone every time with manufacturer-trained technicians and a commitment to providing customers with an easy, effortless customer service experience. You're guaranteed to be left with the service and price you were quoted with customized options for what's best for your home in the long-term. 128 Plumbing, Heating, Cooling & Electric specializes in Installation, Service, and Repair for Boilers, Furnaces, Air Conditioners and HVAC Systems, Tankless Water Heaters, Ductless Mini-Splits and Plumbing. Worried about the cost of your next project? We have options to help you get your repairs on the way! Unfortunately, emergencies don’t wait until you have all of your financial ducts in a row.
"I’d love to leave a 0 star review if I could. The level of disorganization and miscommunication with this company has been staggering. Their customer service is garbage. Don’t waste your time, money, or energy on this company. False promises and sub-par work across the board. We will gladly take our business elsewhere in the future. We had an initial consultation with someone named Darren for a heat pump/furnace replacement. We also lumped in a sub-panel install & dryer replacement. Darren assured us that everything would go smoothly, all the work would get done over the next week. The HVAC & electrical teams showed up several days earlier than expected, which sounds great in theory, but required us to take an unexpected day off work. The wiring they ran to the thermostat was installed hap-hazardly and now just dangles off the HVAC plumbing. The electrical team installed the sub-panel, but installed it too close to our irrigation control box. Now we can’t open the door to the irrigation control box. The electrical team also installed an outlet for the new dryer in a location we wanted, but left the rest for a plumber to finish. When the plumber showed up a week later, he said the dryer could not be installed in that location. He then tried to charge us for additional work that we already had paid for in our initial contract with Darren. (He did actually charge us to cap the gas line to the old dryer). Multiple teams also told us they would haul away our old dryer. That never happened. On top of everything else, we were told (multiple times by Darren and the HVAC team) that, as a part of our 3 year maintenance plan, they would come back quarterly to install a new filter on the furnace. When we called about that today, we were told “that’s not a service we’ve ever offered.” The customer service is absolute garbage. We already feel cheated out of the money the plumber charged us. You’d think after all this, the least they could do is toss in a few filters. We’ll never use this company again. I’d caution anyone else to get EVERYTHING written out in detail before you do business with this company. Better yet, just go to someone else."

"Excellent for maintenance service and emergency work. I subscribed to their maintenance service for several years before they raised the rate, and they always did fine work. When I switched to another maintenance company that missed a flaw in my furnace which caused it to fail on season startup, AccuTemp came out to diagnose the problem the same day with no contract, got the large expensive replacement part for free under warranty, and had it fully installed and working again within 2 calendar days. All that for just the cost of a day's labor!"

Plumbing and heating services FAQs
The average cost to install a new water heater is around $1,300, but you can expect to pay between $875 and $1,750, depending on the kind of water heater, the size of the unit, and the professional chosen to complete the work. Tankless water heaters can push your price higher, as installation is more complicated, with prices as high as $3,500. The location and accessibility of your water heater will play a role in the project cost, as those sitting in tight spaces like a crawl space will drive up your labor costs.
The average cost to unclog a drain is around $200, with prices ranging between $110 and $800, depending on the type of drain and the extent of the clog. Hiring a professional to snake the toilet or sink will usually cost between $110 and $275, a bathtub or shower typically costs around $225, and a main line clog can cost between $100 and $800 based on the severity of the clog and how far beyond the access point the clog sits. Since the labor involved varies, most plumbers will charge an hourly rate for drain cleaning.
