Things went great. Kevin came out around 5 PM one night to look at our unit. He checked out the venter to see if it could be repaired. The minute he opened it up, even I knew it was beyond help. (Terribly corroded) Kevin was able to provide us with an estimate within a day or so and we moved forward with the project. I believe he was able to order the chimney and do the install within 7 days. Great work, super friendly.
Description of Work: We wanted an estimate for an all fuel chimney. Our furnace would not work because the power venter would not kick on. Our normal furnace maintenance company suggested looking into a chimney instead of another power venter. They said it might cost twice as much but it would last a lot longer.

Description of Work: Absolute Mechanical came to fix my boiler, and found the fire box to be rusted out. The boiler was still under warrenty, and they filed the paper work for me and replaced the boiler. I thought the followup calls to fix related problems to the installation were expensive, but the work was great.

Description of Work: Installed central AC (retrofit) to existing house. Work performed on tight schedule which so as not to impede other trades working on a larger renovation project. Installers were excellent to work with; especially appreciated their responsiveness regarding register placement to accommodate furniture and traffic patterns (for floor registers) in some tight spots.

Kevin is a cool, calm, and mature professional who is extremely knowledgeable and treats the client with respect. Work was done on schedule and without drama. My only complaint (goes to quality score) is that the exhaust venting was installed while I wasn't home and is bulky, unattractive, and occassionally vents natural gas fumes onto my deck. I would have appreciated a conversation about expectations regarding the exhaust piping since this is not what I was expecting and nothing like what existed for the previous oil furnace vent.
Description of Work: Oil to Gas Conversion Supply & install gas furnace, water heater & gas piping and hook up to National Grid gas line. Also installed two new Nest thermostats.

The service guy, the son, promised us a cheaper price, but low and behold the owner marked it up $300. Then they played stupid about the price quote. So we payed the bill but won't use them again. I'm not a fan of dishonesty or being treated like liars.

The technician said he would explain to the office what had happened and hopefully they would not charge for the service call. I thanked him for his effort and fully expected to be charged. It turns out they waived the service charge which made me very grateful. I would recommend Absolute Mechanical for their compassion and for not charging me for the mistake I made.
Description of Work: Our heating system suddenly would turn on and not throw heat. I hadn't touched the system so I thought it was malfunctioning and called Absolute Mechanical Inc. He showed up very quickly the same day... within a couple of hours... Turns out my wife thought she smelled gas and shut the gas off to the furnace without me knowing. The issue was identified and resolved quickly., much to my embarrassment since I should have checked this and not assume the valve was never touched.

Outstanding! Price was more than fair, they came when they said they would, finished when they said they would, and the system worked as well as they said it would. I would highly recommend this company for air conditioning and heating needs. - Gerald Moore

Went great, very satisfied, very happy. Was a rather tricky and quot;conversionand quot;, as we also have a radiant heat system that uses the same boiler, and the natural gas boiler (provided at a substantial discount by National Grid) does not provide for a radiant heat system internally, so Kevin had to come up with a solution that allowed everything to still work once we turned off the oil burner (which had its own internal control for the radiant heat system). Kevin talked through the system and the options with us extensively, and designed a system that works better than our old one did. He also found a bunch of inefficient settings in the old system, which he fixed; clearly, Kevin understands our HVAC system better than those who installed it, and/or performed the annual maintenance. Highest marks.
Description of Work: Added a natural gas boiler to our existing heating oil based system. Provided for a switch, to use either gas or oil as the primary fuel. Sorta a "natural gas conversion", except we didn't remove the oil system (at our request). Also converted a propane-fueled kitchen stove to natural gas.

We choose to work with Absolute Mechanical Systems on a big project this summer of converting our heating system from oil to natural gas. The project required some good amount of coordination and management. Kevin Gorgoglione, the head of the company, was a perfect fit for this job. He was knowledgeable, honest, fast, reliable and very pleasant to deal with. His crew was awesome. People that work for him reflect the owner pretty well. They were professional, fast, and very pleasant to deal with. We felt well taken care of. It is November now, system works perfectly and we are enjoying the savings. Natalia Kaylin

Steve arrived early and got to work. It took about 4 hours to do everything. Absolute stands by their work and the products installed. We had some issues with the humidifer making some noises during operation and Steve returned several times to address without charge. In the end, the issue turned out to be a setting needing to be adjusted on the humidifier to reduce the amount of steam output. After making that final adjustment, we have had no issues.

Kevin and his crew descended on our home before 8 a.m. and completed the work by about 6 p.m. that evening. I was amazed at how much they were able to accomplish in one day. We had a 45 year old American Standard boiler and piping replaced by a new, high efficient model. The old system vented through our chimney, in order to get the maximum efficiency out of the new boiler, the duct to the chimney was sealed and new a new vent and flue were installed. The 15 year hot water heater was removed and replaced with a new indirect hot water heater. The crew was courteous and respectful and went about their work professionally. The subcontractor brought into handle the gas line was also professional and efficient. After completion of the work, Kevin took the time to explain to me how all of the components of the system work. We are very happy with our new boiler and hot water heater!
Description of Work: We had a Lochinvar Knight high efficiency boiler with outdoor reset control, floo and piping. An indirect hot water heater was installed. Services included gas and electrical work and removal of old boiler and hotwater heater.
