Letter From Our Founder


I am the proud founder and owner of One Source Home Services. As a family man, I know that an issue with the furnace, air conditioner or other item can be catastrophic. I believe the work should be done safely and correctly the first time, every time.

That is why your satisfaction means so much to me. I sympathize that you are like me and hesitant to let strangers onto your property. One Source was founded to be one of the leading HVAC companies in Sudbury by having it be the type I would want in my own home or business and train my team to do the same.

I have lived in the area for over 25 years and know the best equipment, repair techniques and much more. Give me a call today if you are in need of our services and would like to speak with an expert.

Eric Grenier
Owner, One Source Home Services
