Testimonials

TESTIMONIALS

🗣️ "Reliable, Honest, and So Friendly!"

"Nick Chestnut of Chestnut Mechanical provided excellent and timely service when our older air conditioner needed work. We had a few other companies come out, and they tried to sell us a whole new system. Nick knew how to fix it without replacing the entire unit, which saved us a lot of money. He was prompt, polite, and did a great job. We highly recommend him!" 

— Gail S. | Erie, CO

🛠️ "A Family Business That Treats You Like Family"

"Nick found a gas leak I didn’t even know I had. Then proceeded quickly take care of it and give us the necessary next steps. they are honest and affordable, but also just great people who care about their clients. 100% recommend!

— Bailee G. | Frederick, CO

❄️ "Efficient and Professional"

“Nick and Ally were fantastic to work with. Exceptional communication, super friendly and knowledgable. I e-mailed about my A/C in the evening and Nick came out the next day to diagnose and fix for such a reasonable price - and I was terrified about how much it would cost to fix. House is ice cold this morning - yay! We'll definitely be reaching out to them for any other HVAC needs! Thanks y'all!”
— Kelsey P. | Frederick, CO

❤️ "Support Local, You Won’t Regret It"

“I’m not someone who leaves reviews but sometimes you just have to. Nick just stopped by to see what was going on with my air conditioning unit. Because it was a part he had replaced last year that failed (at a reasonable price) he didn’t charge me. I was floored. This is the type of small business we should all be supporting.”
— Rebecca F. | Erie, CO
