Our family has been using Arnica for heating and air-conditioning for years. I felt compelled to leave this review because I want to give them the credit they deserve! Especially after this last service during 95° weather my father’s old air-conditioning system broke down and they did everything they could to quickly get the part needed and fix it. The office workers are very responsive and supportive. And the tech was knowledgeable, confident, and did a clean job. Thank you to everyone there at Arnica! We appreciate your help!!

The Arnica office team was clear, courteous and responsive when it came to scheduling an assessment visit. The technician arrived on time and was very efficient in his work. They were able to do the repair work that same day within the original visit window, and now I'm back in business with conditioned air flowing again.

Just had the most wonderful experience with Dean who solved an annoying AC leak we've been dealing with for months in 20 minutes.  A true miracle worker! And a charming fellow:)  Couldn't recommend more highly!

Arnica HVAC handled my install exactly how it should be done—professional, clean, and efficient. They set up a system with three split units running off one condenser, and everything was executed flawlessly. The crew showed up on time, worked fast without rushing, and kept the space clean the entire time.

You can tell they know what they’re doing—no shortcuts, no sloppiness. The system looks clean, runs properly, and the quality of the work is obvious. Straightforward, high-level job from start to finish.

I was shopping around for a brand new HVAC system installation during renovation of my place. I found a few companies and compared their services, prices and availability. Arnica looked pretty nice so we picked them.
So far the installation service went pretty well. Everything got installed on time and I was always notified on their schedule which helped a lot to plan accordingly.
Their office manager Rosette kept communication clear and explained me various things I had to go through to make sure everything is smooth and as planned. She helped a lot and made the whole process smooth and clear.
Dean helped to settle various technical aspects before I signed and during the whole process.
I will definitely recommend their service to others. Thank you!

Outstanding from start to finish. I did a whole home Mitsubishi A/C with HyperHeat installation, 11 indoor units with 3 outdoor units in total. Dean came out and did the consultation, then provided a proposal by email and once agreed upon everything was scheduled and installed expeditiously. Any questions or concerns I had along the way were answered quickly.

It’s tough at times to find a good company with good people and workers but Arnica has it all. And if you’re considering a Mitsubishi system they are a Diamond installer which does matter. Dean, Rosette, Marco , Adam and everyone both in the office and on the installation crew were a pleasure to work with.

We decided to switch from oil heat to heat pumps before the federal tax incentives were phased out and after much research chose Arnica to guide us and install the system. Rosette, the office manager, was wonderful at every step of the way, and the technicians, Marco and Mario, and Victor and Cesar, were absolute pros, not only completely knowledgable about the technology and excellent at what they do, but kind and courteous as well. Fair price, excellent customer service, and skilled technicians who did a fantastic job. If you're considering a I highly recommend Arnica.
