Want to start off by saying thanks to Monce for my installation. He was very professional and arrived on time. Looked around for a bit and decided to give him a try and thank god I did. After getting estimates from other companies I realized that they were up charging me for the labor. Monce explained what I needed and gave me an amazing price compared to the other companies. The installation was quick and clean. I HIGHLY RECOMMEND this company for HVAC services. Will be using him again for sure!

My wife and I are thoroughly satisfied with the purchase and installation of our new living room mini split heating and AC unit. I contacted Muncy Monserate (owner and operator of N & M Heating and Cooling LLC) on a Sunday. He came by the next day and explained the mini split unit sizing and pricing options for my living room space. He provided a written proposal the next day. My wife and I decided to have N & M procure the appropriate unit and do the installation. He installed it ...

Our A/C stopped working at 9 pm during a heat wave with a young child in our home. No other local businesses that claim to be open 24/7 were actually open. Monce was able to get here in 20 minutes and fixed the problem immediately. Really nice, super professional, and reasonable pricing with warranties for parts, and even checked the filter just to make sure all bases were covered. I will be using and recommending them exclusively.

Our experience with N&M was phenomenal!!! We called and scheduled an appointment for an estimate on a mini split installation, Monce Montaño came out and explained all of our options and helped us to pick the best installation for us and our home. He was very professional and thorough. The whole experience was great and I would recommend N&M to my friends and family. The workers that came out and installed the system were extremely nice and cleaned up after they were finished and were very informative about the new installation.
