Any recommendations for HVAC company to service WSHPs in downtown Brooklyn?
Hey all,
Any leads for a good HVAC company to service Water Source Heat Pumps in downtown Brooklyn? The company that the building recommends has good techs but is pretty poorly run (tons of no shows and last second cancellations). I've tried my regular HVAC company, but their techs don't seem to know anything about WSHPs and I don't really trust them to service our units.
This is in a big building so a COI would be required.
Thanks much.

How about the original installer.

That's the company the building recommends. They're competent but their back office is (presumably) a mess, because they frequently no show appointments or cancel them last minute. Everyone is extremely frustrated with them. That's why I'm seeing if there are other good options.

My WSHP units went bad. There's a company Elite Air Conditioning & Beyond replaced them. My building required a COI so they provided as well. Got the units replaced and very happy with them. I think James is the owner of the company.

How does that work? Is there like a district ground loop you all tap in to?

Cooling tower on the roof with the building supplying minimum water temp to each apartment, say 50°F

So not a water source heat pump but an air-to-water heat pump.

Water Source to air.
A boiler maintains a low temperature water 50 - 65°F and the individual units maintain what they want and get to pay for electric.

Tower boiler systems were very popular in the 80s and 90s. There were a lot of them around. You have a boiler to bring the water temp up in the winter when the HPs are heating, they are cooling the water and, in the summer, you use a closed-circuit cooler (think water tower with a coil in it) to reject heat these systems always run glycol in the loop.
Glycol temp is usually 80-90 deg or so. Tower may come on around 90 and over to reject heat and the boiler comes on at 75 to maintain lower temp.
No condensing boilers available back then so the boiler needed a 3-way valve.
The beauty of these systems were in large spaces like schools etc where you frequently had one side of the building in the sun needed cooling and the other side needed cooling. With the HPs running some were rejecting heat to the loop and some were taking heat from the loop so the boiler and the water tower didn' run much in the shoulder seasons. They worked very well a lot of building still have these systems.

They are quite reliable. I had buildings with 35 + year old HPs in them. The biggest pain was cleaning the shell & tube heat exchangers and having towers cleaned. Other than that they were somewhat bullet proof. Friedrich Climate masters were the most prevelant around here and quite a few Trane units. Some buildings would have 300 tp 800 units or even more. Condensing boilers did make it better for reheat too.
