Using Costello Climate Control was the best decision I made this past summer. Professional service from the start to the end. My house wasn’t the easiest to install central air because of space issues but Pete was able to design a system that works for me. Pete was always available to answer my questions and finished my job on time without causing any disruption in my busy life with children at home. I will be using his company in the future because of his knowledge, cleanliness and experience.

We loved working with Costello Climate Control! We had issues with our tankless water heater and it wasn't in our budget to replace the tankless. Talking with Pete, he gave us a great solution to our problem without having to be such a big cost. We got a nice new water tank that gives our water the warmth we have needed! Just in time for winter too! Pete is great to work with and goes above and beyond until the project is done!

We are very pleased with the service and installation of our new generator. Peter walked us through the entire process and was always available to answer our questions. All went smoothly from start to finish. Peter is very professional and comfortable to speak with. We will definitely use Costello Climate Control for our future heating/cooling needs.

Costello Climate Control installed a whole-house Generac generator flawlessly for us. For the past 27 years, we’ve owned many homes and dealt with many companies; Peter and his team by far were the best to work with. Everything went extremely smooth. Also, knowledge is power and that’s what we liked about Peter- he has a lot knowledge since he’s been in the business for many years. We highly recommend Costello Climate Control and will certainly be using them when we upgrade our heating system to a high-efficiency system.

Costello Climate Control was responsive to my call for a repair that involved no heat on a very cold day. He was on time and provided a thorough explanation and options for his service. He is more than fair and extremely professional.
