“I can’t say enough great things about Ryan! I had a DIY plumbing project go sideways and needed help on short notice—he showed up promptly and completely saved the day.

Ryan was incredibly kind, courteous, and respectful from the moment he arrived. What really stood out was how he handled the situation—he fixed everything without making me feel embarrassed or judged for not being able to handle it myself. That level of professionalism and empathy is rare.

He worked quickly and efficiently, and before I knew it, everything was back in perfect working order. I’m so grateful for his help and the peace of mind he gave me.

I will absolutely be calling Ryan again for any future plumbing needs and highly recommend him to anyone looking for reliable, professional service!“

“Competitive pricing. Delivered sooner than my main oil provider during the single digit temp days“

“For timeliness, these guys were second to none. I called, and they happened to have an opening the very next day. My wife works from home and I was away that day. She felt secure with Andrew and Alex. Their professional and friendly demeanors enabled her to feel safe home alone; and undisturbed for the most part while she worked her job, and they worked theirs. We had sensitivities to stuff coming out of the ducts prior to NAQS's arrival. After their cleaning and sanitizing of the ducts and vents, the atmosphere was markedly improved. The air is significantly cleaner, fresher.I would give them 5 stars, but they had promised pictures, which we haven't ever received. I'd be happy to amend it to 5 stars if the photos happen to show up in my customer portal. :-)“

“Paul came highly recommended and I can see why! He came out within 24 hours and quickly got my heat working in about 15 min after two other companies couldn't find the problem. Now me and my family are warm and comfortable again for a very reasonable price. I will never use anyone else for my HVAC needs. Thanks Paul!“

“R&M did an amazing job on my furnace. I've had a faint smell of exhaust for well over a year, on a furnace that was serviced yearly by another company. I called R&M to try someone else. He showed me how dirty and out of adjustment my furnace was... like it hasn't been serviced in years. He adjusted everything and gave it a thorough cleaning. Not a hint of odor from my oil furnace now. Very happy with R&M and I highly recommend them.“
