I have been recommending this company for years. Brian O'Neill is been in business for a long time and that means a lot. You have to be good at what you do to achieve longevity. As a real estate agent, I work with contractors all the time and recommend them to my buyers and sellers. I've never had one complaint in I'd say, close to 20 years. Last week was yet another example. A homeowner called me up for help. Her mom passed away and she was clearing out the house to get it ready for the market. It was a hot day and the central air suddenly quit. She's not local and didn't know who else to call because other contractors she'd been told to call were either unresponsive or seemed to be not all that forthright. The company who had been servicing the house forever seemed to be the worst - took a quick look and told her the entire unit needed to be replaced with a staggering bid amount. Of all the contractors who came, Brian was the only one who told her that she did not have to replace the entire unit. All she needed was 1 part. The cost difference on this? Tremendous. Please note that when she called Brian, she'd told him that an estimate for replacement was needed. While my client was surprised, I wasn't. I've heard stories like this about O'Neill Contractors before. My experience with them is that they do excellent work and are highly ethical. It's no wonder they've been in business for a long time. read more

I used them because they installed my mini split system which I guess is pretty straight forward. A few years later it developed a problem which they sent their tech out not once but twice and told me it was fixed $800 total. It broke down a third time even quicker. I called a different company with obviously a more technical know how and they said it was a leak the whole time. O'Neill didn't find it. Obviously they're hiring techs with very little capability. Get a more reputable company. This field of expertise is too expensive for the consumer to have half wits fixing things this complicated. read more

Vince, our regular technician for years, came by to perform our annual winter maintenance on our furnaces. As usual he was on time and performed a thorough inspection and maintenance on our heating system. It is a pleasure to deal with him. read more

Everything about the service call went well. Vince arrived on time, did a thorough assessment of our heating system, changed the filter and got everything ready for the cold weather. Couldn't ask for better service. read more

Thousands of dollars over broken AC/Heat which they said they fixed only for our ceiling to flood and for me to find out they lied about putting in a new pan and back up mechanism to turn it off to prevent flooding. Everything they did was either a short cut or a lie and when I disputed a few of the charges (not all as my CC wouldn't let me go back further than 2 months) they apologized, said they understood and would even send someone to fix our ceiling- more lies! They lied to the CC company and overturned my dispute! read more

Couldnt really rec this group. They replaced my steam boiler years ago when I was a new first time homebuyer. Shortly after I moved into my first home, a 60 yo colonial with a steam system, the boiler cracked and wore out and had to be replaced. They installed a new system but failed to put in a "hartford" equalizer loop. I think they just were cutting corners. Beware of contractors like this b/c they will cut corners when they think they can get away with it. read more

Amazing service. A/C went out on a Sunday. Called Monday morning when O'Neill opened. I didn't have to wait to speak to a REAL person, was put on hold for maybe 2 minutes while appointment with tech was confirmed. Got a 9am to 12pm window for that day. Vince came (put on shoe covers before coming into house) and diagnosed problem within minutes. Part was covered under warranty and had no charge for service call. A/C is running beautifully. House is nice and cold (As I like it!) Glad I have a service contract with O'Neill, they maintain my 5 (!) units and keep my house toasty warm in the winter and cool and pleasant in the summer. read more

They have been my servicing HVAC contractor for close to 10 years and have performed the annual preventative maintenance on both my air conditioning and hot water heating systems. They recently completed the replacement of my central air conditioning unit. The work was performed professionally. The engineers reviewed the existing installation and listened to my performance issues. They corrected many of my existing ductwork installation problems and the installers did a great job with installing the new units. read more

I live in Bergenfield and had heard of Oneill a lot, but I hesitated in calling them afraid that it was going to be too expensive. I was perhaps one of the last home owner around still using oil fuel to heat the home I had looked forward to a "conversion" of my old furnace into a gas furnace. I finally Called them just before Christmas day, a man name Anthony arrived and it took him a few minutes to give me an estimate for a new furnace and the possibility to have AC as well with the same furnace!!!. On the day after Christmas, 4 workers arrived on schedule at 8 am and by lunch time the work was done!. The entire new furnace is powerful and the high tech digital thermostat that came with it, changed our lives forever. Is day and night the difference between oil fuel and gas heat. The house is warmer without even touching the thermostat. They charged me less than $5,000 for the entire job, when everyone else estimated it from $800 to $10,000 read more

O'Neill Contracting came in and condemned my furnace. They replaced the furnace the next day however they neglected to inform me that I should have let water from the faucet drip over as the pipes don't freeze. Well one froze and now they are charging me an extra $1.350 for a burst pipe.. Never will do busy with them again. and george in billing is not a pleasant or helpful person. read more
