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.

Heating — Common Questions
Common causes include a dirty flame sensor, a failing igniter, a thermostat issue, or low refrigerant on a heat pump. It's worth a quick diagnostic before a cold night — small heating faults tend to get worse fast.
Yes. Our mild winters are ideal for heat pumps, which heat and cool efficiently from one system and often cost less to run than traditional gas furnaces in this climate.
