What recent reviews say

Most customers experience fast dispatch, skilled technicians who diagnose problems accurately and explain options clearly, and clean installations. Technicians like Ronald G., Mark, Christian, Brandon, and Josh earn praise for going beyond the call. Two recent one-star reviews raise serious concerns: one customer waited three weeks for a warranty part without supervisor follow-up, while another claims they were pressured to replace a repairable unit and later harassed for a five-star review.

The business operates across Peoria, Phoenix, Mesa, and beyond, handling AC replacements, furnace work, and water heater installs. Maintenance tune-ups start at $17.75. Despite the strong majority five-star rating, the unresolved warranty claim and upsell allegations deserve scrutiny before committing to a major purchase.

Common questions

Can Semper Fi send someone the same evening if my AC breaks down during summer?
Yes. One customer called at 5:30 pm on a Sunday when it was 106 degrees outside and received same-day service with a technician arriving within 15 minutes.
What happens if my new AC unit stops working after purchase?
Warranty should cover repairs, but verify the company registers it before purchase; one customer discovered their warranty was never registered after a parts failure three weeks post-installation.
Are there any upfront fees for initial service calls?
One customer received free troubleshooting and service when only diagnosis was needed with no repairs required.
