Typical Greater Boston range for this kind of work, from regional averages — not a quote from Roman Electric Heating and Cooling. Use it to sanity-check bids, then get the real number in writing.
Standard receptacle swaps — a new dedicated circuit is a bigger job ($350–$750).
Flush mounts, pendants, chandeliers — hung on existing boxes.

Roman Electric Heating and Cooling is a Pembroke shop that pairs electrical work — panel upgrades, wiring, smoke detector installs — with central air conditioning repair and thermostat service, run by owner Michael Roman, who HomeAdvisor's profile credits with 27 years in the trade. The strongest thread across HomeAdvisor and Angi reviews is speed: several 5-star write-ups describe him fitting a job in the next day or driving out at night to get a central AC running again before a family emergency, and more than one reviewer calls the process transparent — a 2025 review says he was "very transparent explaining what needed to be fixed, parts to be purchased etc." Two detailed complaints are worth weighing against that. A 2025 HomeAdvisor review describes a $450 bill for two hours of labor — a $225-an-hour rate — with no upfront estimate, followed by a missed follow-up appointment. A 2026 Angi review describes a rental-unit AC job where the diagnosis alone ran $675, a different unit brand than promised was installed for $850 more, and a temporary loaner had a persistent bad smell before a working unit finally went in on a third visit. Both platforms put him at 4.4 stars — HomeAdvisor from 136 ratings, Angi from 131 — so the praise outweighs the complaints in volume. Still, get a written estimate and confirm the specific unit or parts before work starts, since that's exactly where both negative accounts diverged from what was expected.
I do not recommend Michael Roman based on my experience. Last summer, I contacted him to diagnose and replace the AC in one of my rental units. He responded quickly and spent several hours diagnosing the problem, charging me $675. Afterward, he told me the AC was beyond repair and needed to be replaced. When he returned to install the new unit, he installed a different brand than the one he had originally promised and charged me $850. He also persuaded me to install an AC with a heat pump, even though I did not need that feature. Since I was not available at the property at the time, I felt I had little choice. To make matters worse, he left without testing the new AC. Later, my tenant informed me that it was not working. I had to contact him again, and he installed a temporary AC unit that had a very strong, unpleasant smell. It took a third visit before he finally installed a standard AC that worked properly. Even now, I have not received the receipt he promised, the owner's man
Mike called right away to schedule work, and was able to fit me in THE NEXT DAY. Did the work for the AC unit (maintenance/clean up) and as a master electrician, was able to also re-wire us to use the nest thermostat right away, no need to wait for a different technician to come out to do the work. It was HOT up in the attic, so it was REALLY appreciated! Cleaned everything up very nicely after the job was done as well. Looking forward to him coming back to do our next project-he can do it all!
Michael was professional, transparent, and responsive.
Quick, friendly, expert service to fix to our central A/C.
Mike Roman showed up right on time on July 16, 2025 to find out why my air conditioning was not blowing enough cold air on the second floor of my house. He found the air handler to be clogged with dust and started to clean the air handler. He spent two hours on the job and reported that he needed to come back for another day's work to make some significant modifications to improve the efficiency of my air conditioning system. For the two hours of work on July 16, 2025, he presented me with a bill for $450; that was for labor only. In other words, he was charging me a rate of $225 per hour. The following day, I left him a message that I wanted him to itemize the work he proposed to do when he was to return on July 30th because I might want to scale back the work in the interest of reducing the cost. Anyway, he never presented me with an estimate. Furthermore, he was a no-show for his scheduled appointment on July 30, 2025. In my opinion, Mike Roman is unreliable and crazy expensive.
