The person who answered the phone took a rude tone and hung up on me when I asked they return to the property to remove them. I was very upset because I only had the unit a few months, was still paying off a loan on it, and it was vandalized without my consent.

I went downstairs and said "one last time" because my fingers weren't "working well" after a day of keyboarding ... voila ... I got the snap ring to close for the garbage disposal.

I couldn't be more happy with the whole process from start to finish with Cooling Unlimited…read more Patrick, the comfort advisor, came out to assess what needed to be done to ensure my HVAC would be working properly after installation. In fact he found a way to decrease the cost as we discovered my last unit was way too large for my living space. Everything was explained in great detail and I was able to understand exactly what was going to happen with the installation. From start to finish the process was seamless and the company reached out after to ensure I was satisified and that everything was running smoothly. I will definitely be using this company for all my HVAC needs going forward.

We used Cooling Unlimited to install our heat pumps…read more 1) Cooling Unlimited submitted our Mass Save paperwork incorrectly. After agreeing to complete paperwork for a whole-home rebate, they submitted it as a partial rebate. They were unable to secure our full rebate. After we contacted Mass Save directly, we recovered the full rebate. 2) After the installation, our upstairs heat pump was not operating properly. Cooling Unlimited came out multiple times to inspect the unit and told us it was working adequately. Only after I showed them that the temperature coming out of the upstairs unit was not appropriate did they agree there was an issue. They told us they contacted the manufacturer and ultimately fixed what they described as an issue with the unit. 3) Our upstairs thermostat did not operate correctly after installation. Cooling Unlimited replaced it, but the replacement thermostat still does not measure the temperature correctly. 4) Cooling Unlimited installed a glycol feeder and heat exchanger. Our oil company later told us that the heat exchanger was undersized. We asked Cooling Unlimited to come out and inspect the heat exchanger. Cooling Unlimited then told us they had sent someone from Bosch to our house to inspect the heat exchanger, and that the Bosch technician said it was fine. 5) After all of this, I called Bosch directly. Bosch told me they had no record that Cooling Unlimited had registered our units them and that they had never been contacted from Cooling Unlimited about our units. This made it unclear who Cooling Unlimited had actually contacted when they said they had spoken with the manufacturer. 6) Cooling Unlimited installed incorrectly sized filters in our air handlers and had cut the filters with scissors to make them fit. 7) Cooling Unlimited is now refusing to honor our service contract. We signed a three-year service contract that included annual service. We did not receive service from them in the fall, and they are now saying we cannot receive our annual service because it is spring.

He gave his honest opinions of what could be replaced and what the rough costs were for each component plus labor. He also explained what he thought was the best option to keep our current system running at it's best, which I chose to do. He re-gassed our unit and added a startup capacitor which seems to have done the trick! The outdoor unit kicks on easily, runs quiet and consistently now. And of course the AC blows ice cold now. He even gave recommendations for future maintenance for not only the AC unit but the boiler as well. I can't recommend Total Comfort Mechanical, and James, enough!

At the beginning, I was impressed by their professionalism and promises. However, although they kept saying "yes" and assuring me things would be handled, nothing was actually done. Weeks turned into months with no real progress. My project started in October 2024. The system itself works well, but the sheet metal inspection is still not completed. This has been dragging on far too long, and the lack of follow-through has been extremely frustrating. I strongly recommend avoiding this company. Based on my experience, working with them has been extremely frustrating and disappointing.

The very next day the second heating system I had in an addition failed. I was distraught!! Net Zero gave me a great quote..several thousands less than other HVAC. What they did not tell me that they were only electric heating contractors. So after paying $12,000.00 for installation I now pay an electric bill of $1000.00 a month in the winter. They walked by a brand new gas system in my home..disengaged a second gas heating 50 feet away and installed a unit that is costing me a thousand dollars a month. Not one of the employees ...installers. or project estimators...addressed what a poor and unkind decision this was. Now I have to redo my heating system...sell my house...unable to retire . Would they do the same to their mothers..grandmothers? This is a sad and sorry company. Yes I know I'm a stupid elderly woman with no recourse from people like this.
