FIRST-RATE COMPANY
Hillside is outstanding and is a first-rate company. In over 60 years of dealing with heating companies, we were most impressed with Hillside and everyone from the company that we dealt with.

TRUSTWORTHY & RELIABLE
Hillside installed our heater and air conditioner about 10 years ago; they have maintained it since. I have never had a bad experience with Hillside. They are trustworthy, honest, reliable and reasonably priced.

ALWAYS BEEN GREAT
We have been Hillside customers for over 15 years. In our old house, they supplied oil and maintained our heating and cooling systems. They have always been great! I am very happy to recommend them highly!

FANTASTIC COMPANY
Hillside is a fantastic company! Every time we call for service, they are able to get their technician to our house the same day. The office staff is super kind over the phone, and technicians are the best. Highly recommend!

We Love Our Community
As a third-generation, family-owned and operated business, Hillside has deep roots in our local area. And those roots extend far beyond our business and customer list. One of our core values is the power of giving back to our community. We’re proud to offer financial and in-kind support to a growing number of civic and charitable organizations.
Our primary focus areas have been supporting individuals with disabilities, supporting youth sports – particularly little league baseball, supporting performing arts organizations and programs, and supporting other community organizations that provide critical support to disadvantaged humans and animals alike.
