About Carrier
Founded in 1902 by Willis Carrier — the man credited with inventing modern air conditioning — Carrier is one of the most recognized HVAC names worldwide. Their residential lineup spans three tiers: the Infinity® Series for maximum comfort and efficiency, the Performance Series for a strong mid-range balance, and the Comfort Series for dependable entry-level performance. Carrier systems are known for durability, advanced technology, and strong efficiency ratings — and like any sophisticated equipment, they perform best with regular professional care.

What We Can Do for Your Carrier System
Preventive Maintenance
Regular maintenance is the most effective way to extend the life of your Carrier system and keep it running at peak efficiency. Our comprehensive tune-ups cover cleaning, calibration, safety checks, and system diagnostics — catching small issues before they become expensive repairs.
Diagnosis & Repair
If your Carrier system is underperforming — inconsistent temperatures, unusual noises, rising energy bills — our technicians can diagnose the issue and get it resolved quickly. We carry common parts and work efficiently to minimize disruption to your home.
Infinity® System Service
Carrier’s Infinity® systems with Greenspeed® Intelligence are among the most advanced residential HVAC systems available. These systems use proprietary communicating thermostats and allow remote diagnostics and real-time performance tuning — but that sophistication also means they benefit most from technicians who understand how these systems communicate and self-diagnose. ACI’s team has hands-on experience with Infinity® equipment and knows how to work within its communicating system architecture.
System Evaluation
Not sure whether your Carrier system is worth repairing or if replacement makes more sense? We’ll give you an honest, straightforward assessment based on the age, condition, and efficiency of your equipment — with no pressure toward any particular outcome.
