“Katie was fantastic—truly knowledgeable and professional. She handled our HVAC installation with skill and attention to detail, and it was clear she really knew her stuff. I was especially impressed that the company has an engineer involved to ensure the system is properly sized for the home. That kind of precision and competence gave us a lot of confidence. Everyone we worked with, including Keith from sales and David the tech, was top-notch. We’re really happy with how everything turned out!”

“Kaitie is an absolute rockstar, pardon my language a badass! So sweet and nice. I had a terrible experience with a different company, we didn’t think it would be possible to have central air after that. She came in with so much knowledge and assured us it was possible. Kaitie and Matthew (I think that’s his name) made a dream into a reality, went above and beyond for us. Fantastic team! I don’t ever write reviews but this company is fantastic and deserves every star. I highly recommend!!”
