About Carrier
Carrier is the name most people think of when they think of air conditioning, and for good reason. Willis Carrier designed the first modern air conditioning system back in 1902, and the company bearing his name has been building cooling equipment ever since. Today Carrier is one of the biggest residential HVAC brands in the country. Bryant is a sister brand under the same parent company, so a lot of the engineering overlaps.
In Santa Clarita you'll find Carrier units on everything from 1990s tract homes to newer builds in Valencia and Saugus. They're common, which helps when we need parts.
What Carrier offers
Carrier splits its home equipment into three tiers:
- Infinity: the top line. Variable-speed compressors and blowers, communicating controls, quietest operation.
- Performance: the middle line. Usually two-stage equipment, a good balance of comfort and cost.
- Comfort: the entry line. Single-stage, simpler, easier on the budget.
Within those tiers you'll find central air conditioners, heat pumps, gas furnaces, fan coils and evaporator coils. Carrier also sells ductless mini-split systems for rooms without ductwork, like garage conversions and additions. The Infinity system control ties the whole setup together when you go with matching Infinity equipment.
What's new with Carrier
The big change is refrigerant. Starting in 2025, new central AC and heat pump systems sold in the US moved off R-410A to lower-impact refrigerants, mostly R-454B or R-32. Carrier moved its new residential systems to R-454B, which it markets as Puron Advance. Your existing R-410A system is still legal to run and repair. The catch is that new and old refrigerants don't mix, so a new outdoor unit usually means a matching new indoor coil too.
Beyond refrigerant, the trend is toward variable speed. An Infinity variable-speed system ramps up and down instead of slamming on and off, which keeps temperatures steadier and humidity lower. Carrier has also been pushing heat pumps that hold their heating capacity in colder weather. That matters less in Santa Clarita than in the Midwest, but it's nice on those chilly January mornings in Castaic. Smart controls and phone apps let you check and adjust the system from anywhere.
How Carrier compares
Carrier sits in the premium-to-mid range. Infinity competes head to head with Trane XV and Lennox Signature. Performance and Comfort compete with mid-tier lines from Rheem, American Standard and Goodman.
Where Carrier does well: a huge installed base, so techs know these units, and parts are easy to get through supply houses. Where it costs more: the top-end communicating systems can need brand-matched controls and boards, and those parts aren't cheap. Bryant equipment is close to identical in a lot of cases, so if you're shopping both, compare the installer and the price, not just the badge.
Common problems we fix on Carrier systems
Here's what we see most on Carrier equipment around the valley:
- AC blowing warm air: often a failed capacitor, a contactor, or a low refrigerant charge from a leak.
- System not turning on: tripped float switch, blown fuse on the control board, or a thermostat problem.
- Ice on the refrigerant lines: dirty filter, weak blower, or low charge.
- AC tripping the breaker: failing compressor, shorted fan motor, or a hard-start issue.
- Clogged condensate drain: algae in the line shuts the system down through the safety switch.
- Blank thermostat or control: power issue at the air handler or furnace, sometimes a blown low-voltage fuse.
- Heat pump blowing cold air in winter: stuck reversing valve, defrost problem, or low charge.
