In 2024, Lamco repaired our HVAC system, during the initial diagnosis they quoted us an hourly rate…read morefor the technicians which was mutually agreed and quoted over the phone. Clarification was further provided that the technician would charge for the hours that they worked for (Initial Estimate was ~5hrs work). Once the work was completed, the back office sent an office for the amount for the whole estimated time even though it took less than half the time (~1.5hrs). When the invoice was received it was a shocker since based on the communication prior to the work it was agreed to be per hour basis. After refutation, the invoice was revised to a lower number but still did not reflect the hours the technician worked. Its been a struggle to ensure alignment - I would not recommend them for any work!

I guess it's what I expect out of any company like this though.

Great service - twice…read more I recently bought a home with oil heat, and being my first experience with oil heat, I know nothing about maintenance or even who to call. So I did some research, called a few companies, and picked Prendergast to do a oil burner tuneup because of their reasonable price. The guy came within a week and being a techie guy I want to know how things work so I hung around with the technician and had him explain everything he was doing. He was very courteous and informative and even gave me helpful tips on keeping it running well. A month later our hot water tank sprung a leak and it had to be replaced (~15 years old). I called a number of companies for quotes and Prendergast was the only one to ask me enough questions to give me a serious quote and two options. I ended up choosing the more expensive but much more energy efficient option. Anyhow, I found out later that the state of Massachusetts has a energy efficiency rebate program that would get me $300 back, so I emailed the link to the company and asked for their help. In a few days, I got a letter in the mail with the rebate form all filled out, and a copy of the invoice for proof of purchase. I got my rebate back today (took the state 6 weeks to process it) and just want to share the quality of the customer care I received. Tom, the company owner, was a great help all the way and always responded to phone calls and emails within a day.

I contacted R.H. Young after a heat pump in which they had installed a new motor and serviced…read morenearly a year ago stopped heating. The motor replacement had been done on their recommendation, as my 14-year-old heat pump was beginning to get loud. I was told that after the repairs I could then get many more years of service out of the heat pump, and paid $1840 for the work. They sent out a service technician to check why it wasn't heating. He determined the freon had leaked out and I'd have to schedule any additional repairs with the office. He also said that he would never have repaired a 14-year-old heat pump and would just have recommended replacing it. There was an $220 service charge for his work. When I called the office they said it could take an additional $1000 to track down the source of the leak, (I had never had a leak previous to their work on the heat pump) and provide new freon. I asked to speak to the manager to see if there was a better solution than paying another $1000, when I had already paid them over $2000 for a repair I had gotten very little value for. The manager called when I was out, but said he would call again in the next two days. I called back at his number and got an answering service where I left a message. I never received another call back from him. Apparently RH Young's customer service ends when the customer's check clears. I went ahead and installed a new heat pump, but not through RH Young.

Our boiler worked perfectly the entire time we lived there, except for a bad control panel on the boiler-mate system. They quickly diagnosed the problem and fixed it quickly. Our AC system was repaired once or twice by T+M (it was 25 years old) and then we decided to replace it. T+M's quote came in a few THOUSAND less than Genove's, and they offered to move the compressor to another location for free. They were helpful with documentation for the MassSave program discount, and when I needed a separate cooling estimate document, one of the higher ups completed it and hand delivered it to our mailbox. We got the rebate for the system with no problem, and the AC worked perfectly. They left a little trash in the attic (old insulation and some spare tubing), but I can look the other way for the thousands of dollars I had in my pocket compared to the competitors. We've since moved out of that home, but have decided to give T+M a shot for oil service at our new place. Their billing was fair, in my opinion, and when we needed service, they were quick, often scheduling me first thing in the day before anybody else (Maybe because of location in Waltham?). Oil prices were lower than competitors on the silver plan, so hopefully things continue to go well.

There was pretty extensive and systemic damage but James was able to overhaul the entire boiler in half a day. Now the system is running as good as new.

The job was replacing my broken heat system, including backup heat / air handler (inconveniently in my bathroom ceiling) and heat pump / condenser (inconveniently on the roof of my condo complex). The machine is a Bryant Evolution® Variable-Speed Heat Pump Model 288BNV (which is 18 SEER/12.5 EER cooling efficiency and 11 HSPF) and the air handler is 5-speed variable. The new thermostat is the companion Evolution® Connex™ Control. It took a few weeks to get contracts (including sub-contract), MassSave heat loan sorted and schedule the job, but once is started, the heat replacement itself took only 2 full days, including removal of old equipment, crane to reach the roof and electrical. The heat removal / replacement was exactly per the provided schedule. I think there were at least 6 guys working on the heat equipment at various times. The ceiling construction (4 other guys at various times) took a bit longer than I initially expected (1 day demolition of bathroom, as expected, but 3+ days of ceiling reconstruction, which included frame, drywall, plaster, paint and 2 installed metal hatches), but that was my preferred subcontractor and he did a fantastic job. All the people who came to my house were professional and knowledgeable. The preparation and cleanup was a little inconsistent depending on which guy was there; sometimes it was 30 minutes of prep with paper / plastic on all floor (including through the doorway) and cleaning so thorough that it was cleaner than I usually keep it; other times it was a cloth tarp quickly set down with a quick wipedown and sweep at the end (not as clean as I usually keep it), but I appreciate that everyone made an effort to clean the job site at the end of each day. I haven't had the new, efficient system long enough to see an appreciable change in my energy bills (April was slightly less than 2018 April bill, but hard to say if that's just inconsistent weather or the new system), but I can definitely FEEL the difference. I LOVE the new 5-speed fan system, which goes soft if just maintaining a temperature or harder if needing to change multiple degrees (which it can do much quicker than my old system). Also, it's "smart" enough not to put the fan full blast while there's still cold air in the ducts (my old system used to blow cold air when it first turned on and had only one speed). During the project, they handled most of the MassSave heat loan application and also responded quickly to questions, and were able to deal with challenges (like the narrow height of my bathroom ceiling) and changes (e.g., an unrelated plumbing project in the building which had impact on my condensate drainage pipe). They also submitted both MassSave rebates on my behalf. Although I generally like to support smaller businesses, having a larger business for this project, with a dedicated sales person / project manager (Jason Shea) made this project a lot easier for me. Sometimes you get what you pay for, and I think in this case, choosing a more expensive service gave me a much better experience. Also, on a side note, this project involved people of various skin tones and accents; white guys, Brazilian immigrants, they all did a great job - that's what makes America great, a mix of talented, hard-working and diverse people. I would definitely use Cooling Unlimited again and would recommend to anyone in the area who needs heat replacement.

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.
