Testimonials

Our customers are our biggest fans and they let us know all the time with repeat business and referals to their friends and family.
Our original furnace and house humidifier were in need of replacement. I was referred to Robert and Colegate Heating by a mutual friend. Robert adjusted his schedule to meet my needs and took his time to explain everything, answering all of my questions, and give additional advice on how I could make my home more energy efficient. He and all of his team were a delight to work with! Meeting Robert was a blessing and we stayed nice and warm throughout the cold months and no longer had to fear that the furnace would go out in the middle of the night. I highly recommend Robert and Colegate Heating for their honest work and expertise.

Can’t get any better HVAC company. They actually care and make sure everything is perfect before they are done. No temperature differentials or noisy uncalculated systems. Nothing but the best for their customers and it’s actually done right the first time. If you want find someone for less then you will have to call Colgate out to fix it the right way and spend more. Don’t learn the hard way.

We are very pleased to have a good quality company here in Nunn. Great communication from all staff was helpful with our busy schedules. The guys identified and fixed our heater promptly.’Everyone was very kind. Will definitely use them again.

I called Colegate heating last minute right before a very cold, cold front came through. My furnace had just gone out and needed replaced. Robert the owner came out and had actually been the one to install my furnace almost 20 years ago!! Him and his guys came and had my house warm and toasty before the cold front hit. My 3 kids, wife and I didn’t go cold at all thanks to his fast actions and amazing customer service and CARE for his clients! His guys were very polite and professional and definitely knew what they were doing. Will be having Robert replace my ac as well soon won’t ever use anyone else! Truly amazing business!
