"Mr. Dean was very professional and knowledgeable. He worked efficiently and didn't leave a speck of dirt behind. He went over the new furnace and central air system with me before leaving, making sure I was familiar with the new system operations. I recommend this owner operator company with high regards. Thank you!"

"We were Extremely Satisfied with the Quality of Workmanship and the Product we Decided to go with for HVAC Install... At the same time we had Central Air added, we were tired of window units... Plus, it is Less Expensive to have Both Installed Together!! We Have Really Noticed a Big Difference in how the Rooms in the House are Much More Evenly Heated and How Much More the Heat is Felt while Moving from Room to Room, From Floor to Ceiling!!! The House Has Never Felt So Good!!! A 10+ Star Rating in Our View from the Install and Service from Connelly Heating Air Conditioning!!! In Addition, We Saved over $1,000. with Connelly Heating Air with Bids from 3 other Companies!!! Thank You, Jean Tony S. in Manheim, PA."

"One of the best contractor experiences we have ever had. Jim called the day before to confirm the appointment. Larry the Plumber was so nice to deal with. He put on she covers to protect my wood floors, worked very neatly and gave us some tips about ongoing maintenance. He did a perfect job. This review us for Petro in central NJ. i was not able to change the company location. We hired them through Amazon."

"My home air conditioning wasn't functioning properly. Will Stahl analyzed the problem and had a replacement unit installed in less than 24 hours on the hottest day of the year! You cannot get better or more reliable service that Stahl's Mechanical! And great conversation too!"
