What recent reviews say

German and his crew earn trust through speed and honest pricing. Most customers report same-day or next-day service, installations left spotless, and competitive quotes that undercut competitors. The owner coordinates jobs personally and follows up by phone. One recent complaint flagged a no-show and communication gaps during warranty trouble, a stark outlier among 18 reviews but worth noting for service reliability.

Praise centers on heat pump and AC replacements done quickly and professionally, with customers noting energy savings and loyalty over years. Technicians are described as knowledgeable and respectful, especially during difficult access (attics in 114-degree heat). Fair pricing appears genuine: multiple customers mention shopping around and finding Cardinal cheaper by hundreds of dollars for the same equipment.

Recent shift: One year ago, a customer reported a no-show and poor warranty support-a stark contrast to the consistently positive trend; no similar complaints in more recent reviews, suggesting possible improvement or process change.

Common questions

How fast can Cardinal get me a replacement if my AC fails?
Same-day and next-day installations are documented across recent reviews. One customer had a unit installed by noon the day after emergency contact; another got service within hours of calling on a 114-degree day.
Do I pay for hidden fees or unexpected costs?
No. Reviewers explicitly praise 'no hidden fees' and 'great warranty.' Multiple customers report shopping competitors and finding Cardinal cheaper by hundreds of dollars for the same equipment and warranty terms.
Will German or his team follow up after installation?
Yes. Reviews report the owner walks customers through the new unit, technicians are on-site during install, and follow-up phone calls the next day are standard. One customer flagged a gap in warranty follow-up when issues arose.

Reyna delivers quick fixes and honest pricing to some customers, with standout technicians like Diego and Martin handling routine work smoothly. But the business stumbles on emergency response and accountability: a one-star complaint describes a smoke-smell AC failure with no same-day help and denied refunds, while others report missed appointments and poor follow-up. Installation problems and mismatches between promised and delivered equipment appear in multiple reviews.

Most reviewers praise specific technicians (Nelson, Estevan, Ivan, Eric, JR) for speed, professionalism, and friendliness. Emergency calls get answered within hours, and full system replacements finish in under 4 hours. Two complaints stand out: one technician left rusty water and debris on a customer's belongings without warning or cleanup; another drove recklessly on the freeway and the company didn't return a call after 5 p.m. The business has been operating since 1988 and serves the Phoenix metro area. Most five-star reviews cite clear communication, attention to detail, and courteous service. The company handles AC service, installation, plumbing, boilers, and water heaters, but the negative reviews hint that consistency varies by crew.
