A customer writing in December 2023 described calling RWM Mechanical Services after their water heater died: Rob arrived at 3:30 p.m. that day, and a new heater was in place by 7:30 p.m. The reviewer named him as Rob Markowitz and said they felt comfortable having him in their home. RWM advertises installation, repair and routine maintenance for furnaces, boilers and hydronic heating systems, along with 24/7 emergency service. Google lists a five-star average from nine ratings. In another December 2023 review, a customer whose furnace had been out for several days said Robert arrived an hour after their call. A July 2023 reviewer described Rob coming out on the July 4 holiday after the air conditioning stopped working, ahead of a heat wave. For a planned HVAC replacement, a September 2023 customer praised Rob's price, said he arrived on the agreed date, and described his patient explanations before the work started. A June 2023 customer said RWM worked on their oil tank, water heater and furnace. That reviewer praised Rob's explanations of the oil tank removal and installation, described the process as seamless, and said he resolved issues their oil company had been unable to fix.
Robert came highly recommended. Our furnace had been out for a few days so it was cold in our house. I called Robert he was here an hr later. He is very knowledgeable, efficient and up front with everything. We would definitely recommend.
Our hot water heater died. I got Rob's name from a local referral. I texted his phone and he asked me to call so we could talk more easily. He came to my home at 3:30pm that day and we had a new hot water heater in place by 7:30pm. Rob was very friendly, professional and efficient. I highly recommend Rob Markowitz of RWM Mechanical Services. We were very comfortable having him in our home and we feel he went above and beyond, even skipping dinner, to make sure we had hot water asap.
Rob was very friendly, informative, very reasonably priced, and very professional when replacing my HVAC system. He was punctual and showed up on the agreed date. I had questions before he started and he was very patient in explaining everything. I would highly recommend RWM Mechanical for all you HVAC needs.
Prompt, reliable and awesome service. Called as AC stopped working and Rob came out on July 4th Holiday with upcoming heat wave. Highly recommend.
I highly recommend RWM Mechanical Services who did work on my oil tank, hot water heater, and furnace. Rob was incredibly kind, professional, and communicative. He took the time to explain everything, much more in depth than the other companies I'd gotten quotes from for oil tank removal/installation. He went through all the proper channels to ensure removal and installation went seamlessly and wouldn't cause any permit or other problems down the line. Lastly, Rob was able to quickly remedy and problem solve issues which my oil company could not (but stated they could).
Typical Greater Boston range for this kind of work, from regional averages — not a quote from RWM Mechanical Services. Use it to sanity-check bids, then get the real number in writing.
