Before going with Costello, I got 3 quotes from other companies and Costello beat them by several thousand dollar. The installers were punctual and professional. Had both Heating and AC done in one day. Very happy with the service. I will be using Costello for my new Water heater.

The young Costello service techs ( I believe Anthony and Harold) were knowledgeable and replaced my faulty furnace motor quickly and without incident! I was impressed with their professional customer service; rare in today’s world. Office was professional as well. Thank you.

Gene was friendly, yet professional. He did a great job and answered any questions I had. I also got some extra advice on home projects. I would recommend them to anyone. 👍🏻👍🏻👍🏻
