I called Pinnacle because our AC was running but not cooling our house. Sal was responsive and came that afternoon. He fixed the issue at a reasonable price. He checked in with us the next day to see if the AC was still working well. We will definitely be using Pinnacle again for future HVAC needs.

Hands down the best service anyone could ever ask for. Sal's a pro's pro, and I highly recommend his expertise to anyone in the market for a quality HVAC technician! Professional, knowledgeable, honest, and the most integrity from an individual that I have ever experienced. A welcome breath of fresh air, quite literally. 10 out of 10 stars, and I will be telling all of my friends and family to use Pinnacle for anything HVAC related. Thank you again for everything!

My husband and I just bought a new house and our AC unit wasn't working upon moving in. Sal came out the next day and went above and beyond to help us out! He was knowledgeable, friendly, and even reached out that evening and again the next day to make sure our system was still working properly. Our house is all electric, which is very unique. Sal spent time explaining our new system to us. We will continue working with Sal in the future and recommend him to anyone looking for assistance!

Sal s great he installed 2 central heating units 14 years ago and when one went out in January he over the phone gave me instructions to get heat back up for my family. That’s what I call customer service.

Sal was a life saver this Memorial Day weekend! Was having some issues with thermostat and A/C kicking on and it was about to be an extremely uncomfortable day. Called Pinnacle for the first time and will never call anywhere else for my heating and cooling needs. Sal talked me through everything I could do to troubleshoot the problem. We had A/C!!! Could not have been happier with Sal’s honesty and willingness to help on such a busy weekend. He even followed up with me later in the day to make sure everything went smoothly. Amazing!

Jonathan Gibson
I am extremely happy with the service that I received from Sal and Pinnacle HVAC. I originally requested a quote from Four Seasons to replace my old ancient furnace and was taken back by how high the price was but found the quote from Sal to be much more reasonable. I also appreciated the fact that he offered multiple options at different price points for furnaces with different features. On the initial consultation, Sal took over an hour to walk through every little detail regarding the options I should be looking at. I was also extremely impressed with the prompt communication which is a big sticking point with me. I received regular communication updating me when to expect the installation of my furnace and everything timing wise worked out just as expected. After the furnace was installed, Sal took almost two hours walking me through the operations of the new system and how to set up the thermostat and various programs. Overall, I am very pleased with the product and services received and will definitely use Pinnacle HVAC again for any future needs.

Awesome service. I would highly recommend Pinnacle to anyone looking for an honest and competitive company. Sal is an outstanding individual who will treat you fairly . Came out within 3 hours of my email on a Friday evening and worked until the A/C was fixed.

Furnace Repair all my years as a homeowner have I experienced the professionalism of Sal at Pinnacle. And that's a lot of years. My furnace decided to keep me cool while running the fan but got stingy on supplying heat at the same time. Very annoying when it's cold outside and also with a wife yelling in the background that she's cold every 3 minutes. I probably could have handled the cool temps a little longer but I didn't want to go to jail for killing my wife. So I reached out to Sal and he resolved the problem within the hour. I did not need a new furnace and he had me up and running right away. He was extremely good at what he does. I can only give 5 stars on here otherwise I'd want to give him another as he should be at the top of the list. Hands down the best phone call I have ever made for a repair. The furnace is alive and so is my wife. Win / Win.

Sal at Pinnacle HVAC is a true consummate professional! I am employed as an Engineer and have a background in Mechanical Systems, and Sal completely blew me away (HVAC pun) with his immense knowledge! I received an immediate call back from Sal and had my appointment set for the very next day. Sal walked me through features of our Furnace that I never new even existed. AND he was able to correctly configure our humidifier. By the time he is done, we will have a 100% perfect Furnace and AC, and we will have a new thermostat installed which can better regulate the Hi- and Lo- settings to decrease heating times. Simply give Sal a quick call, and see if in the first 2 minutes if you aren't amazed with his knowledge and professionalism! 12 out of 5 stars!

I have used many contractors for various services and without a doubt I would recommend “Pinnicle HVAC” to family and friends alike. Sal, the owner, was not only knowledgeable and professional but very reasonably priced. 5 stars!

Sal came immediately when our furnace stopped and solved the problem. We are now toasty warm and ready for whatever winter brings. Nothing but thanks and appreciation for his excellent skills and service now and in the past for our HVAC systems. Thank you Sal. Mary Elizabeth

Was looking to get my furnace replaced before winter hit. Decided to give Pinnacle and Sal a call based on their good reviews. I received a quick call back immediately and scheduled an appointment for a consultation. Competitive prices and a great attention to detail made me pull the trigger right away. Couldn't be happier with the new furnace, running smoothly and finally replaced my ancient dinosaur of a furnace I had at home. Very happy overall, highly recommend Pinnacle and Sal! Thanks!

Absolutely outstanding customer service from Pinnacle! We could not be happier with our Lennox furnace/AC purchase. Both Sal and the installers were so very easy to work with. Sal was incredibly knowledgeable, thorough, and flexible. From our first call for an estimate, through completion of our installation, they were consummate professionals. Highly recommended!!
