1.0 Reuben F. New York, NY

After working with Gil Karni of 365 Kool for over 2 years I cannot recommend that anyone do business with Gil or his company. I paid Gil over $7000 to select & install a new WSHP console unit in my apartment and, from day one, the unit he installed never worked properly. Having spent as much as I did, I asked Gil for his help troubleshooting. Throughout the course of our relationship, Gil repeatedly ignored my calls or would tell me that he'd call me back only for me to hear nothing until I called again. Rather than try to help me, Gil pushed the blame of my problems to the building's water supply--even though my other unit, and neighbors' other units, operated normally. The way that Gil operates his business--ignoring customers' concerns and brushing off blame to others--is deserving of a poor review. I hope that others will read about my experience and think twice about working with Gil.

5.0 Stacey S. Fort Lauderdale, FL

After speaking with Gil, who took the time to explain and breakdown what his company would do for our furnace that needed a major cleaning, we decided to go with him. His guys came out to inspect it for themselves and were very professional and well equipped to do the job. I have not had service like this in a long time. 356 Kool did a great job from start to finish. Perfect company for quick and accurate response.

365Kool did a great Job from start to finish was leaving town on a Saturday 2/13/21 boiler started malfunctioning on Wednesday 2/10/21 explained to Gil at 365Kool my situation didn't want to return to home to busted water pipes. Gil had a great deal of knowledge about boilers and water heaters, and promised he could install both water heater and boiler in 1 day which was that Friday 2/12/21 and kept his promise. My vacation was worry free, return to a warm home the following week, Thank you Gil at 365Kool

Had failure of the Boiler Auto Feed that caused water to come up through the system. Company was able to get a Tech to us quickly on a cold day and was able to remedy the condition quickly

2.0 Errol M. Queens, NY

Did not solve or identify my problem.

4.0 Lawrence D. Bronx, NY

Unfortunately they did not follow up on a concern I share with them after the work was completed.I sent a review of the techs from the perspective of the tenant.Also the tech said that there was a cap or cover that they couldn't find ,but they assured her that they would get one and have it installed.We've heard nothing.

5.0 Dyann C. College Point, NY

Our A/C unit needed freon as it was not cooling to capacity. I called for service on a Sat. and they arrived within a few hours as scheduled by their dispatcher. They added the freon, cleaned both of our condensers, and we decided to add a leak guard product so as not to have this issue next year. Joe and Gill, in the office, were professional and friendly as were the the technicians. I would highly recommend them and they will be our go to A/C and heating company should the need arise in the future!

5.0 Nick G. New York, NY

Their staff members were very calm over the phone call and properly listened to my needs.We had scheduled a same day appointment last week and now AC is working fine. Reasonable prices and the amazing customer service.

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
    We use 3rd party data sources to check the history of the principal/owner of the business for bankruptcy filings by or against them.
