Coolair Inc

Their lack of professionalism is astounding and the truth is that it was
like pulling teeth to get them to do what I needed. They misplaced one
of my AC units and didn't care one bit so I was left feeling very uneasy
about the whole situation until the day of installation when they
showed up with my 2 AC units (after having to send all the copies of
proof that they in fact had picked up 2 - they were insisting that it
was just one and I am glad I held on to my receipts)

In the past three years, we have had to replace two large wall units at considerable expense.  In addition, we have had to replace the defective compressors in two units.  On one occasion, CoolAir collected our air conditioning unit to take it to the shop so they could replace the compressor, and they returned it three weeks later steam-cleaned, but without the promised new parts.  It conked out again within twenty-four hours.   This type of service is habitual with them.   Their labor fees are exorbitant; usually over $350, and they have never consented to waive them, even when the units were under warranty.  (In fact, they once phoned me to say if I didn't authorize their labor fee, they would hold the unit hostage and simply not return it.)  They often do not answer the phone, and rarely confirm appointments.   When confronted about their ineptitude, they are surly and argumentative on the telephone.  Admittedly, I live in New York City, and service providers can be arrogant, uncommunicative, or merely ineffectual.  Rarely have I encountered a company that was all three.   We have reported them to the New York City Department of Consumer Affairs, and to the Better Business Bureau. 

AVOID THIS COMPANY!!! 
This has been a nightmare from the moment they showed up - they sent a man who doesn't work on this type of unit - a split unit where part of the unit (the condensor is outside of the apartment) - so I had to wait again for the right service man/men. 
The guys who came found a clog in my drain - they unclogged it.  They did not fix the louver - it still sticks.  They claimed I had not had the unit professionally cleaned so they strongly recommended it - and since they were already there, I could add on a professional cleaning for a lower price.  I agreed - big mistake!  Another $300 later, they actually broke my air conditioner!  The little door that covers part of the front, underside of the unit was forced off and is now broken.  The guy said he'd try to find the part to replace it - in the meantime he taped the door back on.  The next day, the door fell off - it happened to be when my son was napping - otherwise, his train table is under that a/c and right where that door dropped and fell. 
Coolair said they'd send me an invoice (in the mail) for the work they did - as well as ordering the door they broke.  They never called me back, despite my emailing them photos of the part they broke - they never sent an invoice so now my credit card company is having trouble with my dispute because I don't have any invoice from them.  How convenient for them!
To top it off, their service guy is sleazy - his boss said to top up our freon on the house (because I had to wait over 6 hours for them to come - because they screwed up - and the guy told me it should be $250 but he'll give it to me for nothing and I should "take care of him" - I gave him $100 and later discovered his boss told him to do it for nothing!
All in all - this has been a horrible experience where I was seriously overcharged - and now have a damaged unit - where the little door will no longer stay on it at all - I ordered a new piece and it won't stay on because the damaged the unit itself. 
They have completely stopped returning my phone calls - which is why I am finally leaving this review - I tried very hard to deal with them - before leaving a negative review - they have left me no choice. 
Find another air conditioner repair company - DO NOT use these people - you will be sorry!

Cool Air picked up my air conditioner last Friday to steam clean it.  I
was told I would probably have it back by Wednesday.  On the work order
it says the work will take 3-5 business days.  It's now Friday, the 6th
business day, & I still have no word on when I will get my air
conditioner back.  All I am told when I phone is that they call when the
air conditioner is ready.  I will never use Cool Air again & would
discourage any one else from using them.
