"My experience working with CR Mechanical Services couldn't have been better. While looking to replace my furnace and air conditioner, I requested quotes from 4 different companies and CR Mechanical Services stood head and shoulders above the others. They provided a thorough HVAC consultation, listened to and answered my questions, and proposed a great new system at an unbeatable price. Rick and Craig just finished the installation today - right on time and right on schedule - and were friendly and professional through it all. My thanks to them, and my highest recommendation to all who are looking for an HVAC company."

"Unfortunately, our homes and the systems that provide heat, electric, plumbing, etc. do not last forever and must from time to time get repaired and replaced. I have owned a home for over thirty four years. While over the years I have used many HVAC companies, I cannot think of a more professional, friendly, informative and quality heating and air conditioning company than One Hour Heating and Air Conditioning."

"Thought it was a plumbing issue, but turned out to be an issue with air conditioner. They were prompt in responding to the emergency call. HVAC responder was knowledgeable. Price for furnace and AC was horribly overpriced!"

He is amazing, always listens to my concerns, educates me, and builds my trust. An amazing team, focused on delivering trusting customer service. A debt of gratitude to Full Efficiency heating and cooling."
