Sal is super thorough and helpful and kind. He presents options and makes but doesn't force recommendations.

Sal was able to solve the issue I was having with my thermostat and furnace. He even taught me many things about my I-comfort thermostat that will be useful going forward. And, even though it’s not what he came out for, he noticed my furnace humidifier wasn’t even hooked up and took the time to connect it and show me how it is actually supposed to work. Pinnacle will be my go to for all future heating and cooling needs!

A couple years prior Sal Pinnacle installed a new high efficiency Lennox furnace. Our central air conditioning needed to be replaced and Sal came right out and did a fantastic job of installing the new Lennox Elite XC20 series, and i Comfort S30 Smart Thermostat. Sal does great work and treats the customer with respect. Sal always explains what options and products you can purchase. Better call Sal, you wouldn't regret it.

The service was fantastic.

Very quick response, I have had them out last year also with another unrelated concern and the service was fantastic. I have referred Pinnacle to 3 other neighbors and they are all so very happy. Great bang for the buck. Like their honesty, follow up and that they don't try to up sell you.

Highly recommend Pinnacle for your next project.

Pinnacle Heating and Cooling installed my new Trane furnace, AC and electronic air cleaner. Sal Esposito and his crew were professional and courteous during the entire project. I was completely satisfied with their work and would highly recommend Pinnacle for your next project.

I was on the verge of closing on the sale of my house, and upon inspection the buyers wanted a few repairs done. The problem is I had limited time to get them done. I read reviews online and decided to give Pinnacle a call. GREAT CHOICE! Sal came out to my house the very next day, went through our HVAC system and made the repairs necessary to close on my house on time. The invoice was detailed, the customer service and follow up after repair was all first class. I know most customers leave reviews when unhappy, but I will be the first to tell you this company is a 10!

I was told by a different heating & cooling company that my freon is leaking & that I needed to purchase a new AC unit. So in my search for pricing a new unit, I called Pinnacle. Sal & Bill came out the next day, ran some diagnostics & found that the freon was low, but nothing that warranted my replacing the entire AC unit. They did what needed to be done and saved me about $3000! They also took a look at my furnace & informed me that I am only using 1/2 of its capabilities. It's a 2 stage furnace & I only have a 1 stage thermostat, so I'm going to have them come out in the fall to tune up the furnace & install a 2 stage thermostat which will make the house warmer in the winter & run the furnace more efficiently. These guys are GREAT! I would (and will) recommend them to anyone & everyone. Thanks Sal & Bill!

I called Pinnacle. They returned my call in about 30 minutes and were out at my house within 24 hours for a non-emergency call. They were on time for the appointment, clean, courteous and professional. They were reasonably priced and took a lot of time explaining what they thought the problem was and gave some give advice on how to try to fix it without spending more money than necessary. I would DEFINATELY call them again!!!

We were in need of a new AC unit for the start of spring/summer. We had several companies come out, inspect our home, and give us quotes on mid-top level AC units. When we met Sal and Bill you just got a sense of people working hard, giving you a quality product, and not ripping you off. Pinnacle is an OUTSTANDING company that goes above and beyond customer care. Sal is truly passionate about what service he is providing for your home and what you will get in return. Both our boys have seasonal allergies, Sal was incredibly knowledgeable about HEPA systems and filters that would help reduce allergens in our home. We would highly recommend Pinnacle to anyone looking for a quality product, at a competitive price, and with great customer service.
