Hear from Happy A/C and Heating Clients

See how we’ve helped these Long Island residents and business owners keep their indoor areas comfortable.

You may not have heard of these guys, they are not the biggest on Long Island but they are reliable and honest. Had a big problem with my air conditioning. I called, they came over and took care of the problem. These guys were fabulous. No run around, no up-sell -- straight forward and all fixed. I would use these guys for my air conditioning and heating any time.

Great service, workers were gentlemen. One of the workers spilled some oil on my pavers, they applied a solvent and took care of the issue immediately. Site was clean after install of a 16 seer 5 ton system. Highly recommend them.

Extremely reliable and honest HVAC company. We have used several over the last year for our heat pumps and Eric and his company are the best!
