Hennessey Heating & Cooling

Hennessey did a great job installing our mini split system. We really appreciated the thorough job and ensuring that the unit was installed keeping all indoor/outdoor aesthetics and curb appeal in mind. Would recommend to anyone looking for these services!

I called Hennessy to ask if they could assist me with checking/installing a gas valve for my stove before the new one was delivered. They did an awesome job! They were quick and efficient. Marko was courteous and let me know exactly what was needed. I will definitely call them again for any HVAC needs I may have. I would highly recommend them!!

We had a great experience with this company, Brian does a great job, explain every kind of doubt we had , always on time , clean work , very nice people to work with .And the price is really good. We are going to continue calling them for anything we need . Thank you very much for your great job !!

Had a great experience with Brian. His communication was excellent & he was quick to get the job done! Would recommend to anyone needing services he offers!

Brian and Marco do great work. They are competent, hard-working, and reliable. I always know that I’ll be pleased with the results and I can’t recommend them enough.

I’ll be using this company from now on for my heating and cooling needs. Brian dispatched someone to come quickly and Marco got the job done quickly and explained the steps he took to repair our HVAC.

Excellent service. Brian is extremely knowledgeable, and more than willing to explain technical details when I had questions. Can't rate highly enough.

It has been several years now since installation and everything continues to run smoothly. We had a very efficient model installed and there has been a significant decrease in our energy usage. It is so quiet we don’t even realize it’s on, but we know every time our neighbor’s system kicks on :) Brian has been very responsive with follow up questions and regular preventative maintenance.

We used Hennessey Heating & Cooling to replace our old furnace to a high efficiency furnace and new AC unit. He offered different options in terms of features and efficiency. He clearly explained the differences between them, pros/cons of replacing a standard furnace with a high efficiency one, and was easy to talk to throughout the process.

Brain and Marco were wonderful. Brian explained everything and answered all of our questions. He was very accommodating to our schedule and worked with us to get it done. Would highly recommend!
