Original Donnelly - where customers have sent their friends since 1898. The only family of the ORIGINAL Donnellys in the heating and cooling business still operating today. Our forefathers brought an honest work ethic that is often overlooked in today's workplace. We recognize this and instill these values and ethics into our employees today.This is a large part of why we have been in business for so long. There are very few companies that say that they are still family owned and family operated for more than 115 years. Today, we are proud to continue our grandfather's legacy. We are a Carrier Factory Authorized Dealer and a Mitsubishi Diamond Dealer.
