Customer experience

Here what customers have to say about our service

My elderly mom had no AC. I went to her apartment and it was 80 degrees - not safe for anyone, especially an elderly woman. I called All Service and explained the situation - they had someone there within an hour! The technician was so kind and patient with my mom and got the unit working. I will recommend them to anyone and everyone. Thank you for taking care of my mom!!!

My Central Air crapped out the first week of July '24 and I was getting a lot of high quotes to replace my condenser and air handler. I contacted All Service on Friday 7/12 and their price was significantly better than any of the other quotes I got. Within 5 days they had everything installed and running perfect. Every person on the phone is pleasant and professional, the techs who arrived on site left the workspace in better condition than they found it! From the first phone call to the finished product, All Service was top tier quality. Would give 6 stars if Google would allow me!

Charlie Sheridan - Long Island, NY

I highly recommend All Service. They have gone above and beyond with providing services to our new home. Their entire team is reliable, professional, trustworthy, and friendly. We are so grateful to have them for all our home needs.

Michael Francesca - Long Island, NY

We recently redid the house and the HVAC system. After several disappointing encounters with other firms, we came around to All Service. They were on the spot after a fire destroyed our AC systems and we used them ever since. They do a great job all the time and our favorite tech is Frank. We even named our Furnace after him! 🙂
