We used Denillo for an unexpected repair on a Saturday when our furnace stopped working. They came very quickly, did the work quickly and restored our heat within hours of our first call. I will definitely call them again for future needs.

Guy Denillo came to the house to give us an estimate. We bought a Trane energy efficient furnace and AC. Denillo is a family business. Very professional. Job was done in timely manner. Would highly recommend Denillo Heating & Cooling.

Denillo's is a great company. They have done a lot of work for us in the past. This time was a tune up & the technician also fixed something free of charge. In the past they have repaired & replaced our air conditioning system. They are courteous, professional, and provide quality work. Will always call them first for anything that would need done.

He refuses to answer or offer to pay. He was belligerent to my wife and very uncooperative in this matter. I need a new computer.
Description of Work: His workers came to fix our air condition. While they were working one of the workers broke our laptop computer with software which cost with everything $600. He did not offer to pay for a replacement. I tried to contact him several times and no answers. He is a lousy businessman. He needs to pay me compensation for the broken computer. He refuses to talk to me.

I had a contractor for heating and AC, I didn't have a very good experience with them but it was a sub contractor. The name of the company is Denillo, it is the guy's last name. He was difficult to work with. He didn't really plan very well on how to wire our 3rd floor and so we ended up putting window air conditioning units in it and it kept on tripping the circuit breaker that he put in because he put like way too many outlets per circuit. He didn't think about it very much and then they took our basement apart to do all the wiring in the basement and didn't take the wires down when they were done although they said they would. It was fine as far as the timeline, it was more of the customer service afterwards. I don't like them.
Description of Work: It was for basic heating and air conditioning work and he did electrical for us too. The service had to be 2 years ago. He re-wired our 3rd floor and installed the central air unit.

Went very well.
Description of Work: I want to say in the spirit of Holiday season Denillo services assisted my friend in need by putting a switch free of charge and also not charging for the part and did it promptly, so that her son could comeback from the hospital to home . Amazing owner they have done some work for me in my Lawrenceville house and also for my friend who referred his company to us. I and my friends will not call for anybody else of our heating and cooling needs Thank you Denillo you guys are the best

I had a New Trane Furnace installed by Guy Denillo the year before. Everything went very smoothly, so I had Denillo Heating and Cooling install a New Trane Whole house Air Conditioner. The Trane furnace was built to accept the Air Conditioner so all went smoothly. Guy Denillo gave me a good price and good service. They are located in the same Brentwood community I live in, so his great reputation was already known to me and I wasn't disappointed. They inspect my furnace and air conditioner annually to prevent problems. I couldn't be happier. Chuck Thomas

Description of Work: Denillo Heating removed my ancient dead furnace and installed a new Trane furnace. There was no hard sell and after the purchase there was an hour or so measuring then the Trane was installed in one day. |The workers were professional and left my basement spotless upon completion. |Everyone I dealt with was curteous and even stupid questions were answered with no fuss. |I would definitely recommend them to others.

Woke up in the morning - no heat! 29 degrees out!! Not a good day!! Called Denillo Heating and Cooling, Inc. They came out the same day and diagnosed the problem quickly. He had the part on the truck. He was able to fix it with minimal disruption. The service technician was professional and knowledgeable. We would definitely recommend them to anyone.
