Fixed Generator Installation
From the moment I hired them to the very end they where fantastic. Brandon was very pleasant well mannered and explained everything about the investment I was going to make. His crew was extremely well versed in the installation and professional. They stayed very late to complete the job. They cleaned up and made sure I was satisfied. More importantly after the setup was completed, if I had any problems or questions they would be here if needed. I would highly recommend them.

AquaTech is the most technically proficient in conjunction with prompt courteous and very friendly service. Our Generac Unit has given us piece of mind and knowing that AquaTech is there for us and only a phone call away means no more worrying about storms.

Contracted Lowe’s home improvement for generator purchase and installation. Installation was contracted to Aquatech inc. who did a great job with installation and arranging for permits.

Compared to their competition AquaTech offered the best price and service hands down. The price was a fraction of what the competitor wanted for a 3 unit AC replacement and installation and it came with an amazing warranty and guarantee. Chris and his workers did everything possible to get the job done soon as summer is approaching. I have dealt with a lot of repairmen, contractors, etc. and Chrisâ workers exceeded my expectations. They left their work space spotless, carefully moved all the furniture for me and the installation itself was flawless. They are definitely the best on Staten Island and I would recommend them to anyone who wants quality work at a great price. Thank you again AquaTech Team!! -Brian

Our technician Antoine called when he was on the way (right in the middle of our two hour window), serviced my generator thoroughly, made some adjustments and the told me what to watch out for in the future. He was competent, friendly and the service was reasonably priced. Bravo!

Every employee of AquaTech went above and beyond to explain and perform every detail so that we understood every aspect of the job. They all answer all the questions and seek further replies when they thought we needed more explanation! They are all very respectful of my property and aim to please in every aspect.

They are really nice people. Family are all involved and one more helpful than the next. Showed up on time and all of the guys were clean and respectful of my home. I had a slight issue on a Sunday and within 2 hours the owner was at my front door!! I could not believe itâ ¦ Really recommend them.

This is the second time I used the company. I reported my water heater leak last night to Chris. He checked it this morning and got it replaced in the afternoon. His crew was efficient and professional. Highly recommended.

Had Chris troubleshoot and service my Trane gas heating unit - he performed a simple cleaning of the thermal coupling to the unit because of carbon build up, he got the unit working for the day but the following day that the unit had malfunctioned and began blowing out cold air from the fan, it has been 2 weeks that I have been calling only to be transfer to a receptionist and answering service for the past 2 weeks now with no luck. I did not mind paying the $125 labor fee in cash but this being the case I feel that I have no recourse but to ascertain the company's license number 1387924 and possibly filing a complaint on several online sites reviews. I honestly spoke with the receptionist and when I mentioned that I will consider reporting my online review she considered that as a threat - well at least I should have had my calls returned and my issue resolved but none of that happened, Thank God I contacted another service who immediately pinpointed and troubleshooted my Tranes gas unit for a fraction of the cost.

"Edwin C. says "...did not mind paying the $125 labor fee..." "another service who immediately pinpointed and troubleshooted my Tranes gas unit for a fraction of the cost....". Pinpointed and troubleshooted. What about fix? And at fraction of $125? A professional?"

Aquatech Mechanical did an excellent job on replacing failed central A/C system at my home as well as added the mini split unit at my home gym. I rarely recommend any contractors but I this is the one I couldn't resist the urge to recommend them as I am extremely pleased with their work and service. Everything from the initial estimate till final install went seamlessly. The owner Chris is a pleasure to deal with as is his crew. He is very polite, knowledgeable , professional and so is his entire team. Both installs were done on time and with a great amount of professionalism. I highly recommend this company. As a side note, I recommended them to 2 of my friends who used them to service their AC system and the generator and they both thanked me for the recommendation.
