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!

Sal is the absolute best. He’s an expert in the field and throughly explains all issues and recommendations. I appreciated that he gave me multiple options at different price points. He was on time and finished the job in the amount of time he had said it would take. He responds quickly and was very easy to communicate with. I would highly recommend utilizing his business!

Furnace Service

These guys checked out my furnace which was not working properly. He diagnosed the problem quickly and was very professional. He also gave me all the options I had. I decided to repair instead of replacing my old furnace. Would definitely recommend them to friends and family.

HVAC System Replacement

Being a first time homeowner I had no idea what to look for in a new furnace and air conditioner. The owner of Pinnacle, Sal, provided numerous options for us and price points on Lennox equipment. When you meet Sal you’ll be amazed by his technical knowledge. He even beat out the estimate that CostCo provided! The day of the install went smoothly. The Pinnacle crew showed up on time and cleaned up afterwards. They took their time with the install and showed me how to control the EchoBee thermostat as well. I didn’t even have to worry about filing energy savings rebates with Nicor and ComEd either. The owner filed the paperwork on our behalf and gave us an instant rebate when it was time to write the check! Thanks Pinnacle!

New Furnace Installation

Came out and checked for an hour to see what the issue was with my furnace / air conditioning unit. Found the problem and worked with me to get a new unit ordered and installed. After installation went over everything with the new unit to make sure I understood it all.

Very thorough, reasonable and courteous.

Sal was great. He came out right away to assess the problem. Our AC quit in the middle of our kids birthday party, and since it was 29 years old we knew it had to be replaced. He had a new and improved unit up and running within a few days right after Memorial Day a busy time of the year for HVAC. Sal was very thorough, reasonable and courteous. He even called to check on us following the install. I highly recommend Pinnacle for your heating and AC issues
