"Comment: I was finally able to find a responsive and reliable plumber. Jason returned my call promptly and showed up on time for both the estimate and several days later when he completed the job. He replaced two toilets, an outside spigot and well as installing several cut off valves. All work was done with care and cleanup was great. Jason also made suggestions for other work that I am considering. All-in-all this was a positive experience and I highly recommend Jason and Aquarius Master Plumbing and Heating for your plumbing needs. Thanks again, Jason."

"Jonathan came out initially to install a smart thermostat for us. The previous owner didn't maintain/repair the dual zone system or whole home humidifier. They also left us with a rats nest of HVAC wires. After talking our options over he installed new dampers, a new humidifier, and installed and configured the two smart thermostats. When we had an issue with a fan running constantly, Jonathan was quick and helpful to point me in the right direction to resolve it without a service call. Would definitely use and recommend him and his crew for other HVAC projects."

"Hudson Valley was by far the best company I have ever worked with in any area of home improvement and repair. They came on time, carefully evaluated what needed to be done and explained all of my options. They arrived at 330pm and stayed till 9pm to complete the repair to my air conditioning unit. This repair even included opening a wall to access the unit. I had two other companies look at this job and both said the unit could not be repaired and wanted me to have them install it for a court that ran as much as $10,000. Hudson did the job for a repair cost only and the unit works perfectly. In summary, they are honest, professional, skilled and â Great people.â Look no further than Hudson for any HVAC needs."

"Jon is top notch. We have used his services for a 3 zone mini split install at our home in Brooklyn. His pricing is on target, and the quality of work is above and beyond. There is a complete attention to details. The work is done quickly and efficiently. We have also used Jon for service calls for rental properties upstate, and a recent natural gas boiler replacement in a multi family building. He built the new boiler, re arranged multiple hot water heaters and installed all new piping. The work when complete looks like a piece of art. He has helped us to modernize the property with this install. We highly recommend Hollins Mechanical for any and all HVAC related needs"

"I hired John (Carpenter) to do some small tasks on my Mom’s House. His work was great. I asked if he could take on more work for us. He removed the old tile, linoleum and cabinets, and installed new. My Mother and I are very pleased. I would definitely recommend John."
