Providing residential heating and air conditioning maintenance, repair and installation of furnaces, boilers, heat pumps, ductless and high velocity AC. 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."

"DO NOT USE 128 PLUMBING We have had a lot of work done on our house since moving in a few years ago and have worked with countless plumbers, contractors, electricians, etc. Everyone does the job a little different but they do what you pay them to do, and generally do it well. 128 Plumbing is the absolute exception. We have had them out 3 times now, and need a 4th but are going to foot the bill with a new plumber just to keep them from messing up anything else. We hired them to replace our water heater, simple enough. It was pricey and they did up sell on some expensive add-ons but nothing beyond what most in the area charge. Day of install, no one shows up in the assigned window. We call after another 2 hours go by and they said they forgot we were on the schedule...? After we insist they need to come as we have no hot water and I took off work, 2 disgruntled guys show up at the end of the day. The two guys that came were completely unaware of the PEX system in our basement. They only know pro-press. Fine, use what you know, but to not even "know of" the other connection types and systems out there? How exactly did they complete apprenticing without learning that? Then they were careless and decided to balance our old heavy water heater on our new vinyl picket fence instead of walking 10 extra feet to use the gate, breaking our fence. They also didn't finish installing the $800 leak shut off valve, and just left it turned off and unplugged - luckily I noticed, plugged it in, and got it setup online. They would rather mess with each other and get out of there, than actually do their job. A few weeks later, the valve triggers, our new tank was leaking. They never checked the water pressure and our main was too high (and had been, this wasn't just a spike). They wanted $90 to even come see what was leaking before we knew about the pressure. Then another $1400 to install an expansion tank and Pressure reducer valve (I totally get paying for this, its a new service/product, but the price is much higher than local quotes so I mention it). I put that on hold to talk to some local plumbers to see what they would charge, and come to learn, they installed the water heater wrong in the first place. The auto-shut off valve is in between our vacuum relief valve and our heater, completely isolating the vacuum relief in the exact situations you need it...a draining or siphoned heater. They want another $90 to come back and "look at it" to decide if they will fix the install they messed up just a few weeks ago. At this point I would rather pay full price to a new plumber to come in and fix their egregious mistakes and make sure my home is properly plumbed."

FAQs for window a/c unit installation projects in Boston, MA

Running a window air conditioner to cool a small room often costs less than $4 per day, making it cheaper than central air for single-room cooling. However, central air might be more efficient if you're using multiple window units or need to cool a space larger than 1,000 square feet. Choosing the right size AC is crucial—a unit that's too big or small can waste energy and increase costs.

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
