Testimonial from Peta H. in Queens, NY
used Absolute Mechanical to do an oil to gas/steam to water conversion last fall (Oct 2010). They installed a Freewatt CoGen plant in my Queens residence which is a gas-powered Honda MCHP engine,  supplementary boiler and indirect water heater that produces both electicity and heat. The system is net-metered so that excess electricity generated by the Honda engine is fed back to the grid (if my house doesn't use it).

They did an amazing job! Not only is the equipment efficient, reliable, and redundant (not to mention beautiful ---  plumbing is a work of art!), but the team of people who did the work were probably the most knowledgeable HVAC team I have ever come across.

All of the engineers/plumbers/electricians were respectful of my space and family, organized and tidy, not to mention they were remarkably fast considering the complexity of work they completed. Absolute Mechanical is the kind of contractor that will be there when they say they will be there and measure 3 times before they make a first cut - precision oriented. I highly recommend them for ANY HVAC work since they know how to appropriately size equipment and install it (even in old houses like mine, a 100yr old Tudor).

I searched for an engineering team like this for about 3-4 months before I came across them. NO ONE compared. After speaking to atleast 4 of their references, I heard the same words...reliable, remarkable, knowledgeable, more-than-satisfied.

I can't say enough good things about them. They give you good advice and they complete what they start for a fair price.
 
Testimonial from David C. in Brooklyn, NY
They converted my old oil system to a high efficiency gas system.  They are top notch.  The system is now installed and operational in my five story brownstone.  The owner of Absolute Mechanical (AM) is Gennady Tsakh.  He is extremely intelligent, knowledgeable about heating physics, mechanics, and technology, and eager to share his knowledge with his customers and potential customers.  He educated me about a whole different approach to heating a house than I had ever heard about before, though it seems to be common in Europe.  
 
Boiler operation is based on the outside temperature, rather than an interior thermostat.  The system constantly puts out heat to compensate for heat loss from the house – and the system water temperature is lower than it would be if heat were provided on and off and on and off, based on an interior thermostat.  So, under this “outdoor thermal reset” system, the house temperature is kept constant, and hopefully comfortable, rather than fluctuating under a conventional temperature control system between being too warm when the heat is on, and too cold just before the interior thermostat would turn the furnace on again.  Although I was initially skeptical about not having a conventional interior thermostat to control the heat, the idea made a lot of sense to me, once I thought about it.  I could tell the first day the system was operational that what was good in theory would be very good in practice.
 
Gennady goes out of his way to do thing right, and then some.  
 
One example: About a month before work was to start, but after I signed the contract, my old oil furnace stopped working.  Absolute Mechanical got that old boiler operational at no charge to me.
 
Another example: When the system was recently put into operation, I noticed a sound that was resonating through the house.  Gennady isolated the source, determined the cause – the particular configuration of the circulation pumps – and will be changing the pumps next week.  
 
Members of the crew at Absolute Mechanical are extremely capable, knowledgeable, and alert.  One example:  His foreman, Anatoli, happened to notice that some old piping for domestic cold water was leaking.  Gennady and he determined that the pipe was anodized steel, not copper, and that the leak could result in a burst pipe at any time.  They replaced that pipe during the system conversion and installation, and prevented what could have been a badly flooded basement. 
 
The installation layout, including boiler placement, indirect hot water heater placement, piping, and the like, is neat and orderly – a big change from the tangled maze of piping in my old system.
 
Bottom line, I’m glad I decided to have Absolute do my oil to gas conversion.  They did a great job, and I’m looking forward to more comfortable heating at a significantly lower cost this winter.
 
Testimonial from Betty M. in Brooklyn, NY

Gennady has a great team of highly professional people at Absolute Mechanical. He was the only one who came here, assessed the situation, suggested and tried on the spot and immediately after several ways to alleviate the problem and finally fixed it. In the sea of technicians in NYC, these people stand out as the ones who are able to quickly; 1. Figure out what the problem is, 2. Offer and try different solutions, on the spot and immediately after, 3. Fix stuff! Most importantly, too, they were always available to communicate with us, weekdays and weekends, and they were always honest in terms of their promises. In fact, they accomplished all they promised!

Dennis and Natasha C: their boiler was leaking on very cold days. We replaced it quickly and with our famous high quality

 

Joe M: Another satisfied customer. We installed a Weil McLain ultra series 3 condensing boilers in combination with Weil McLain ultra indirect fired hot water heater. The system was working from day one with no problems.
