O'Neill Contracting HVAC

Got a number of estimates to do our second zone AC / Furnace unit, but after sitting down with Ernes twice - Oneill won out. Not the cheapest but nowhere near our highest estimate. We did a LOT of homework on this project. They did pretty much a perfect install. On time, efficient and took a lot of care in the home. And unit works like a charm. Even connected the new Thermostats i had bought . Rare NNJ case of great service at a competitive and fair price. Strong Recommendation here.

We just had our 20 year old central air and a 50+ year old gas boiler replaced by O'Neill Contracting. We had three other estimates from other companies which were way overpriced. O'Neill's estimate was within our budget and decided to hire them. The installation techs did a great job! They were hard working and courteous. If you're looking for a trustworthy, customer focused company, look no further. The entire O'Neill team were awesome. My wife and I thank you!

O’Neill contracting recently replaced my home’s heating and AC system and they did a fantastic job! Both Ernie and Vince were great to work with. I could not be happier with the whole experience every step of the way. Everyone was very professional, knowledgeable, and they delivered as promised. I would highly recommend them to anyone with HVAC needs!

While searching for a good HVAC contractor, I saw O’Neill Contracting’s vehicle at a neighbor’s house down the street, and selected them to repair the thermostat that stopped functioning. The house has two gas furnaces and two AC compressors. Yighit, the tech who came was professional, personable, and knowledgeable. I decided to have them service both furnaces, which had not been serviced in several years. I’m glad to have found a very good & reputable contractor and will hire them again.

We’ve been using O’Neil Contracting HVAC for our regular service as well as for heating and air conditioning issues, and they’ve been excellent every time. They are always responsive, professional, and reliable. The service technicians are knowledgeable, courteous, and take the time to explain everything clearly. It’s a company you can count on, and we wouldn’t hesitate to recommend them to anyone looking for quality HVAC service.
