These guys were awesome! Clever solution to tricky problem getting duct work from one attic to another non connected attic. Professional, clean, and hard working guys. Would use again.

Rick and Mike (everyone forgets Mike :) Did a great job and even followed up a week or so later to make sure the install was working correctly. I want to keep these guys a secret so if I need anything in the future they are available. Honest and trustworthy with mad skills. You can't go wrong with R&M.

I am by nature a bargain hunter, but I also know business. I look for a low price but I also am a skeptic on low bids, When I met Rick he seamed too honest to be true, but R&M Mech. turned out to be my best choice. I am a pain in the **** and Rick and Mike tolerated me and really go beyond what a person could expect. Sad what we expect is to get ripped off and have a lawyer on retainer. I hope everyone chooses R&M Mechanical and I also hope you have as good of experience with R&M as I did. Now a year later, I call back R&M to up fit my house Oil FHW heating system. I wanted to go gas (Propane only avail in Derry) to replace my ageing trianco burner that lived about 5 years longer than it should have. I am my usual pain in the kiester self and do my research on the boiler I want....2nd day of install atm I will follow up, but so far all is good.
Description of Work: Mini Split, a 3 Ton unit (big one :)) Rick and Mike did this August of 2015.

I started my search for contractors on Angie's list and had a few estimates. Why I selected R&M is as follows: First contact was with Rick by phone, he answered a few questions that I had but most importantly he preferred to use the Mitsubishi system which is what I wanted. We set an appointment for 5/11 at 4PM he was running ahead of schedule and contacted me to see if it was ok. We met he listened to what I wanted to accomplish he took measurements (none of the others did) and told me he would send me an email later tonight for a quote on the machine that would be the best size for our home. That evening I got the quote for the 24k unit. ( This was the only quote for the 24K unit I got some for the 18K and the 12K) I know the 12k would not have been big enough and wan't too sure about the 18K. The best part was their price was over $1,000 less than the other quotes. We set an appointment the next day for 5PM and he was there on time. We signed the contract gave him a deposit and surprisingly he gave me an install date of 5/24 at 7:30AM. To be honest I never thought that it would actually happen on that day. But sure enough on 5/24 at 7:20 AM they were in my driveway. It was a drizzly rotten day but you would never know it by the way they went about their work. At about 2PM their truck was pulling out of the driveway the job completely done the job site totally cleaned up. Rick and Mike did EVERYTHING they said they were going to do exactly when they said they were going to do it. The mitsubishi ductless split is great it cools the house down in no tme at all. I highly recommend them both.

He stayed at my house for a couple of hours because it was a bit more complicated. The pipes from the boiler had a blockage because of the cold. Rick explained everything in a very coherent way. He told us what to look for as the evening wore on, and recommended we keep the heat off until the blockage resolved to make sure if there was a burst pipe we didn't end up with a flood in the basement. We put a heater in the basement and by the morning the pipe was unblocked. He told us if we had any problems, we should give him a call. He cleaned his work area completely and I would definitely employ him in the future.
Description of Work: I called on President's Day because the heat on the first floor of my house was not working and within 3 hours he was at my house. Rick came and quickly diagnosed the problem as a circulating pump. He had everything with him and got quickly to work.

Rick & Mike are nothing short of exceptional! They installed a new furnace & whole house humidifier, cleaned up sloppy plumbing, wiring and duck work on the old furnace and installed new brackets on piping and sealed everything up so that it is air tight and efficient. They vacuumed and cleaned the furnace room, removed all debris and returned everything to it's original location. They take the time and care to ensure the leave it better than they found it. And they saved us $$$, between $3-5K for the cost of a new furnace. Now we have a new energy efficient HVAC system that will save me 10-20% a month on my utility bill and provide heat and A/C for years! These two are professional in every sense of the word, they listen to the customer's needs, look out for the customer's best interest and provide phenomenal service. I HIGHLY recommend R&M Mechanical to anyone that needs HVAC work in the Londonderry/Southern NH area.

Excellent! Highly recommend.
Description of Work: Called R&M because our furnace wasn't working, Rick came out same day, on time and had it up and running in no time. He also did a complete check of the furnace and provided recommendations for future work which included cost saving improvements, definitely recommend R&M Mechanical. I plan on using Rick for all future HVAC issues at our house.

A/C Wasn't working. We called a couple of providers who never responded, then called Rick. Rick came out the next day, examined the whole system, and had us back up and running in an hour for ~$150. We mentioned a couple of other problems we were having such as sweating on the main duct, and arranged to have him come back. They came and went above and beyond, including cleaning out the drain pipe, installing a safety switch, mounting our thermostat on the wall (it was hanging off). All told the second visit came to about $250 including parts. We have already recommended Rick to friends.

It went very well. They came when they said they would. They were responsive, responsible, punctual and professional. We were very pleased with their workmanship and attitude throughout the project. They were neat, organized and friendly. They kept us informed of their progress as they went along. It was a pleasure to do business with them. We had another rather simple home project done that was rife with glitches and human error. In contrast, R&M Mechanical Services was a real breath of fresh air. We would gladly and unhesitatingly recommend them for all of the aforementioned reasons.
