Absolute Mechanical Co Inc

.

It took several months to do the job. They were extremely professional, they did what they said they were going to do, and they brought a very high level of skill and experience to the job. They have helped me achieve, tremendous energy savings.

The job took a few months to finish. This is a rental building with 18 apartments and two stores in upper Manhattan. Gennady Tsakh and his crew concentrated on the installation while Sasha Tsakh had the hard job to coordinate the job with the schedule of the tenants and she was there to smooth and solve all the problems.The company is reliable, they answer the phones immediately and they are there for every request or question. Knowing that they will come any time if a need arises is very comforting. We passed an uneventful winter with minor adjustments of the system and expect more winters like that.You can see photos of the work in this link:http://www.highefficiencyheatingnyc.com/2011_09_01_archive.html

They are competent, organized, and respectful. They are also very professional.

Absolute Mechanical 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 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 subtle high pitched sound that was resonating in parts of 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 know what they're doing. They did a great job, and I’m looking forward to more comfortable heating at a significantly lower cost this winter.
