Cambridge Air Conditioning & Heating Corp

Cambridge installed a mini split heat pump system for my home. The initial install went okay, but they did not cover the floors, fully clean up, and one guy used my tools without asking. This winter, we have 2 problematic rooms using ducted mini split. When outside temps were in the teens, the ducted mini splits heated to 60 degrees, unable to reach the set point of 72. With outdoor temps of 30's, the room temp is 4-6 degrees under 72. They sent 2 techs to troubleshoot the thermostat. It initially read 68. After they tinkered with it, it displayed 74. My other room went from 54 to 59. They said they had to go into the advanced settings to make it warmer. Great, as long as it works. I looked into the manual after and found a setting called Indoor Temperature Display Offset which allows you to add or subtract 5 from the room temperature display. I checked the setting and turns out the techs just changed this setting to make it seem like the room was warmer than it actually was by adding 5 to the display. Shady work. I eventually got Dave and Tom on the phone. They were defensive and tried to discredit my concerns. Tom said it is normal for a 5 degree difference. I called Mitsubishi and they told me that was a lie. About the room temp offset, Dave aggressively said it is impossible (it's in the manual), and illegal to do that, and that all the techs did was resync it. Then why was the offset at +5? I did a resync myself to see if that changes the offset to +5 - it doesn't. Dave asked me about room insulation and air sealing - which I then asked if isn't all of that considered when sizing the system? Dave got really offended and proceeded to condescendingly lectured me about how he does a manual J calc for every project. I'm just a home owner trying to understand why his room isn't being heated well - why is that unacceptable to ask? I asked Dave what my options are. His response: Turn up the thermostat (hah). In the end, they said they would send a tech out. Weeks later and no attempts to fix this issue. So much for that 1 year warranty. Mitsubishi recommended to get a different guy to come as they had doubts about the installation. And wow were they right. The ducted units had amateurish duct work - full of inefficient bends, creating a high external static system that restricts air flow - the main reason why the rooms weren't heating well. They are supposed to operate in low static pressure, and the new contractor said it should look more like this - [*** Link removed ***] Night and day comparison to the way Cambridge installed my units (see attached images). He had major concerns for one outdoor unit on the NW side. It was low to the ground and snow and ice can affect it. There was no wind guard on it, and the winds usually come from the NW, which can trigger more defrost cycle. Boy was he right... Yesterday (20 degrees, snowy, windy), there was ice on the lower coils for most of the day. The condensers were in defrost cycles every 15 minutes of run time, for 10 minutes at a time! During those times, there is no heat being generated. My home was at 62 degrees the entire day with the fireplace in use! I even asked Dave during the install if snow would be an issue and he said to just shovel it. What a tremendous understatement that was! Thanks Cambridge - for taking tens of thousands of dollars just to heat my home to sub 60. I don't expect or demand any resolution from Cambridge, and am cutting ties with them completely (I doubt they would even come at this point anyways). I've lost complete trust in them. What I should have done was just pay slightly more for a more competent company that actually understands the intricacies of properly heating a home. If you're trying to use these heat pumps as your main heat source, I suggest you do the same. But if you're just getting mini splits for cooling or supplemental heat, I think you can get by with their workmanship if you really wanted to.

David and is crew were very knowledgeable and professional Installing the 2 1/2 ton unit, split unit. They had the unit installed and operating with in 6 hours. Explained the operation of the two thermostats, cleaned and took the garbage with them. Tom in office made sure of the appointment and took care of the paper work for guarantee and rebate. I received three proposals and Cambridge was the best

It wasn't that expensive. I thought they did a very good job. They were quick. The job came out very neat. It looked good. I was overall, very satisfied.

Professional, courteous, punctual service. I couldn't be happier with the results. They provided an electrician to complete the work due to the fact I needed to upgrade my panel. House is cool and comfortable and the outside looks great. Very clean look no messy wires. Excellent job.

Dave & his guys did a awesome job, I loved the fact that Dave came to job every day & put on his tool belt. Great job

Cambridge was one of four companies we contacted for estimates and and could not have been more pleased with the outcome. Even though we began this project deep into and quot;the season,and quot; we were able to get an estimate within two days and the installation completed within two weeks. The cost of these systems is crazy, but the price Cambridge quoted (which was neither the lowest nor highest) included Mitsubishi machines (which we wanted). No one else we contacted was able to match Cambridge's quote for the Mitsubishis. As well, they are authorized by Mitsubishi and their installers received installation and service training. I was concerned about the and quot;look of the final product - so many I have seen have so many ducts running in so many directions that the house appears as a refinery. I needn't have worried. Our installers (Nick, Jeff, and Charlie) were artists. During installation, whenever more than one option presented itself, we were always included in the decision. The efficiency of their work was impressive, utilizing the absolute minimal amount of ducting. The result was a single line looking like no more than a drain pipe, and although this required that the drilled holes on three floors be aligned such that the final run was perfectly vertical, the crew accomplished that feat (I know it's crazy, but if the line was noticeably tilting, I would never have been pleased). Ours is an older house filled with surprises whenever work is done on it. This job was no different but, no matter what problem arose, the installers had the perfect fix. These guys knew their business. They arrived promptly each day (the install took nearly 4 days, a bit longer than they anticipated, I think), wasted no time, and although they worked in every room of the house, you really would never have known they were there. They cleaned inside and out at the end of each day (embarrassingly) doing a better job than we do. If I am no longer choking on the thought of what I just spent for air conditioning, The guys at Cambridge are largely responsible. They are as professional a company as any I have done business with. The quality of their work is excellent and their people wonderful. As for the air conditioning, it is absolutely fantastic.

I would like to thank Dave and Lyle and ALL his crew for a job well done. You hear horror stories today when you have to have work done. Not the case with cambridge Dave and Lyle were a pleasure to work with with no stories. They said something it happened. You can't ask for more than that. Thanks again guys, you did a great job!

Dave, Lyle, and their staff were responsive and professional. They did great work, quick and clean. They have been available to answer any questions. This work was done in home while undergoing extensive renovation, they accomodated our schedule and we're extremely pleased. There price was substantially lower than any other bidder.

Dave and his team did a fantastic job and everything went as expected. They worked very neat, clean, efficient, and around my busy schedule. They took the time to address any questions and concerns that I had before, during, and after the job was finished. We are very satisified with quality of service they provided.
