What Homeowners Say About Aim High HVAC

Nathaniel DeanNathaniel Dean ★★★★★ Travis was outstanding, great service, would highly recommend this company.Rebecca IsaacsonRebecca Isaacson ★★★★★ David was incredible! He came out same day!! He stayed for almost 4 hours to make sure the job was done and done well. And he played ping pong with my son while we were waiting from my husband!You all are the absolute best!!!David WagnerDavid Wagner ★★★★★ Brent was great during the recent maintenance visit. He was on time (early actually), communicated clearly, and was thorough in his work. Par for the course for Aim High. Every service technician who has ever come to our house has been very knowledgeable and easy to work with. Best HVAC vendor I have used over 18 years as a home owner.Jim HesterJim Hester ★★★★★ Aim High installed a furnace and water heater for me in November 2023. Great experience. Quality service and products. Very professional, cleaned up the work space and left it looking better than when they arrived.Just this week my AC stopped working and they came to check on it. Some minor adjustments were needed from the when the furnace was installed last winter. Their office responded to my calls promptly, and they were able to arrive and diagnose the problem quickly and make the fix. Best of all was that since the AC issue related to something with the furnace install last winter (that couldn’t be tested at that time) there was no charge for the AC fix. I feel Aim High and everyone who I have dealt with there is focused on doing a quality job for their clients. My experience has been that they are honest, fair, transparent, respectful and courteous. It’s nice to feel like I have someone I can call that I can trust and will do great work.js_loader
