AC on the Roof
Does anybody know if all AC units mounted on the roof need a permit no matter what size? I think a disgruntled subcontractor has dropped a dime on a new 25 ton unit (it has permits). FDNY wants to see the 25 ton paper work which I can produce but there is a little 3 ton unit behind it and I'm thinking I'll pretend the 3 ton doesn't exist. The asshole also said the sprinkler system is "defective" what ever that means. That's not a civilian complaint, that's someone who knows violation nomenclature. Apparently anyone can call in a complaint regarding a leaking sprinkler head or closed valve and the fire department has to check it out.

Recommendation Phils Air
We recently had two mini-split aircontioners installed by Phils Air Conditioning and Heating. They did an amazing job and were extremely helpful with some tricky issues we had - even coming back two months later to change a pipe layout which didn't work with our new deck build.
Phil was very reasonably priced and his team was really a pleasure to work with.
The system they installed also did a wonderful job through August with far superior cooling with similar impact on our monthly electricity bill than previous window units.
For the interested we have two yard compressors with internal units on parlor and first (one above parlor) floor. Pipework was well disguised where visible by the finish guys who work with Phil.

Roof Top AC Noise
Can anybody recommend a sound engineer who could come up with a solution to noise generated by a large 2 fan roof top AC condenser. All fan noise no vibrations. My RadioShack meter says about 12Db increase when they're on. Not really a legal issue. Tenant has agreed to fix since it is the owner that is being annoyed.

Window A/C Storage?
Can anyone recommend a company that will store window unit air conditioners? One that is relatively inexpensive, preferably. The place we have used recently increased their prices to $250 per unit, which is almost as much as a new air conditioner!

Water Cooled AC
Is there any kind of water cooled AC equipment that is allowed in NYC that does not involve the use of a cooling tower or other recycling of the heated water. Having an argument with a small Building owner whose tenant is desperate to put only a condenser on the roof and replace the rotten donnage. Compressor stays in the store.

Mr Slim 24k BTU A/C
MS24WN & MU24WN Mr. Slim Unit (indoor/outdoor), cooling only, 24k BTU.
Used since summer of '04 in our parlor floor to fully cool down the whole floor - works great.
Being replaced with an integrated all house split-system so selling this one to a home that can use it.
You can google on line with the # of the unit to see more about it.
Unit works perfectly for us for our whole parlor (keeps it cool but not ice box cold for the space), some superficial denting to the external unit but no affect on performance.
Comes with operation instructions, but since was installed for us by A/C folks (Weston Bros) we do not have an install manual or brackets. Would probably need to have good knowledge to install yourself or get a good A/C person to install.
$500 or best offer for the unit.

Installing Thermostat for HVAC
We have a three McQuay PTAC HVAC wall units in our condo. One of them is controlled by an external digital thermostat, while the other two are controlled by the more basic internal controls, which consist of a red/blue button system and a dial to control the temparature. I'd like to install the digital control for these two units. I opened up the units to install the thermostate myself but it looks as though the digital thermostat was installed using a custom rewiring. Does anyone have any recommendations on an HVAC person who can install the digital thermostat for the other two units or thoughts on this?
