High Efficiency

I chose high efficiency over all of the other top companies on the cape due to their willingness to install the specific equipment that I wanted and their attention to detail from the look of previous installs I was shown at consult. When they were finished with my job all ducts, dampers, vents, the furnace, the condenser and water heater were plumb, square and level. Every seam in the system was properly taped and care was taken on every strip. The gas lines, plumbing and electrical wires were all in parallel to each other and neat. Everything was labeled and crisp. Not one inch of the install looks sloppy or rushed.
Shout out to the owner Craig who came to the site and spent his time to answer any questions and a big shout out to the technicians - they were all incredible to my kids, courteous and just straight professional. Good humor all around and great attitudes.. My most sincere thanks to all of you. I 100% recommend High Efficiency moving forward - they will be my first choice with all future projects.

I used High Efficiency for the first time for maintenance on my Furnace and Hot Water boiler. I heard some odd noises coming from the Furnace and was concerned. My realtor recommended them. I called High Efficiency and worked with Madison, who was great, getting an appointment set-up. The technician, Craig, arrived on time and was polite and professional. He cleaned and inspected the boiler and then explained his findings. I will absolutely use them for my annual service/maintenance going forward. I highly recommend High Efficiency.

I can’t say enough about high efficiency. They are true to their name. Budget was right down the middle of the road with the cape. It was a difficult job with a tight old cape attic but I never heard a grunt or an issue. They asked for 7 days and got it done in 3. Left the rooms clean enough to sleep in, my wife was so thrilled that we didn’t have to sleep on the pull out. We’ll be using them for the maintenance of the system and our boiler. Quality of works manshop was unbelievable. 8 out of 5

We hired High Efficiency to design and install a mini split system for our home. The team was professional, courteous, and friendly, from the initial meeting with Anthony, to the Last day of the 5-day project managed by Matt and Dustin. The quality of the install and effectiveness of the system exceeded our expectations; we should have done this year's ago! It would be inappropriate to overlook the people in the High Efficiency organization. You will not find a company with a staff of people with higher character. I was expecting the professionalism they brought; however, my wife and I couldn't speak enough about the quality of individuals that comprise the High Efficiency team; Wow! Thank you to everyone involved in our home project. We will not hesitate to recommend High Efficiency with the upmost of confidence.

I called High Efficiency in a panic recently when I noticed there might be something wrong with my outside condenser that gives us heat and A/C depending on the season. Since they installed the unit I figured they were the ones to call. They were here within a week and did a thorough cleaning and tune up of the entire system including indoor units. They also noticed my condenser was not level and placed blocks under the legs to make it right...more than asked for...thank you Joe D. and Laura L

The High Efficiency Team was fantastic. From the office staff communicating and helping with the loan process, to the on site team of plumbers and electricians etc. (Josh & Chris were awesome!), to inspection and oversight by the owner, Craig....we couldn't have been happier. Any concerns were addressed immediately. They worked quickly, efficiently and even cleaned up! We are very happy with our new system and look forward to saving money in the future.

The Team at High Efficiency LLC of Cape Cod in Sandwich Mass is knowledgeable, pleasant, an Craig Mattson quickly diagnosed my problem!!!Thank all of your dedicated Team, Jeanne, Madison, Vanessa, Josh and Craig who "GET THE JOB DONE RIGHT"!!!! The community is in trustworthy hands!!!!

We are two High Efficiency fans and have been for several years. Craig has assembled a professional, knowledgable, friendly, and helpful business team. We have had both our heating and AC systems installed and maintained by High Efficiency. They are excellent problem-solvers and are always quick to respond--which immediately reduces stress as homeowners.

Today is a perfect example. I noticed a very large puddle of water around the water heater. Calling at 3:30 p.m. on a Friday, I was wondering if they could help me resolve this problem before the weekend. The very friendly and helpful receptionist, transfered me to Cindy in the Service Department. Cindy was great! She patiently and genuinely listened to me, collected important information, communicated with her service personnel and then immediately called me back with a solution. Cindy scheduled a technician to come to the house within two hours. . . on a late-afternoon Friday. Impressive in this world!

As it turns out, their heating system was in great shape and doing what a quality water heater should do--not fail. The issue was with the water pump which loss power due to a circuit being tripped.

Thank you High Efficiency!

We used High Efficiency for a complete cleaning of the AC head units. The technician, Craig, arrived on time and was very polite and professional. He did an excellent job of getting the heads cleaned of mold and dirt. They look like new! And no more smells coming from the units. I am very pleased with the job he did and his professionalism while in our home. I plan on using them yearly.

We have used High Efficiency for all our major plumbing and HVAC needs. We have had many large projects over the last 4 years to update and also replace most of our major systems in our restaurant.
We have always been more than satisfied with the work and professionalism of the employees from the front office to the licensed plumbers handling the work.
They have handled our smaller project with the same care and professionalism not matter the size.
All work is professionally done and all installations have been of high quality.
If you want quality work and professional representation , I highly recommend you call High Efficiency for any size project you have. You will not be disappointed.
