Our AC quit on a 102° afternoon and Glacier had a tech at the house within two hours. Diagnosed it fast, had the part on the truck, and we were cold again before dinner. Genuinely impressed.

Replaced our 14-year-old system with a high-efficiency unit. The crew was clean, on time, and walked me through everything. Our summer electric bill dropped noticeably.

Honest company. They could have sold me a whole new system but instead fixed the actual problem for a fraction of the cost. That earned my business for life.

Signed up for the Glacier Club after a tune-up. The tech found a weak capacitor before it failed. Exactly the kind of proactive service you want in the middle of a Texas summer.

Professional, on time, and knowledgeable about our older Alamo Heights home. Explained the ductwork options clearly with no pressure. Highly recommend.

Installed a mini-split in our garage workshop. Quiet, efficient, and the install looks factory-clean. Couldn't be happier.

Commercial HVAC — Common Questions
