Should I pick Carrier or Trane for a new AC or heat pump in Minnesota?
Carrier and Trane are two of the names homeowners bring up most often when they replace central air, and on cooling the two are very close. Both sell a basic single-stage condenser, a middle tier with more than one speed, and a variable-speed top tier, and both now build them on R-454B refrigerant. Where they differ is in naming, controls, warranty paperwork and their cold-climate heat pumps. This page covers air conditioning and heat pumps. For gas furnaces, see our Trane vs Carrier furnace comparison.
Same ladder, different rung names
Carrier's outdoor units come in Infinity, Performance and Comfort series. Comfort condensers are single-stage. Performance mixes single-stage and two-stage units with a variable-speed heat pump. Infinity outdoor units are variable-speed under the Greenspeed Intelligence name. Trane now groups systems as Premier, Priority and Choice and is moving away from the XV, XR and XL codes printed on older paperwork. Its variable-speed units carry the TruComfort name, and its middle units are "multi-speed" inverter models that sit between two-stage and fully variable.
For a typical Twin Cities rambler or two-story, the step from single-stage to a staged or variable-speed unit is the one you will notice. Our 2-stage vs variable-speed guide explains the difference in plain terms. Brand-by-brand details are on our Carrier and Trane pages.
Which cold-climate heat pumps do Carrier and Trane sell?
Both brands now sell a heat pump built for real winters. Carrier's is the Infinity 21 Ultimate Cold Climate Heat Pump, and Carrier lists heating operation down to -23°F. Trane's top model is the 20 TruComfort Variable Speed Cold Climate Heat Pump. Trane says it holds 100% of its heating capacity down to 5°F and keeps running to -20°F. Trane also offers low-profile cold-climate models in its 19, 17 and 16 multi-speed lines.
Read those numbers carefully. "Keeps operating" is not the same as "keeps up with your house." Every air-source heat pump puts out less heat as the outdoor temperature falls, and a Minnesota design day sits well below zero. That is why most installs here keep backup heat: a gas furnace for dual fuel, or electric resistance strips in the air handler. The right plan depends on your fuel, your ductwork and your electric rates. Our heat pump service page covers how we set the switchover, and Do Heat Pumps Work in Minnesota Winters? goes through what to expect in January.
When you compare the two cold-climate quotes, ask for the published heating capacity at 5°F and at the lowest temperature listed for the exact size quoted. That tells you more than the model name.
Humid Julys and dehumidification
Minnesota summers are short but muggy, and a lot of comfort complaints come from humidity, not temperature. Variable-speed units from either brand help here because they run long at low speed, which keeps the indoor coil cold and wet enough to pull moisture out. Carrier's Infinity System Control manages humidity along with temperature. Trane's SC360 system controller, part of Trane Link, handles enhanced dehumidification on its side.
The biggest humidity mistake is oversizing. A condenser that is too big for the house cools the air fast, shuts off before it dries anything and leaves the basement clammy. That is true of every brand, and it is why we size with a Manual J load calculation instead of matching the old unit's tonnage.
What do Carrier and Trane communicating controls mean for repairs?
The top tiers of both brands are communicating systems. Carrier's Infinity System Control is built for Infinity equipment only. Trane's UX360 works only with Trane's communicating variable-speed systems. That brings better diagnostics and tighter control, but it also means the thermostat, and often the furnace or air handler, should match the outdoor unit. Single-stage and most staged units from either brand run on a standard thermostat.
Repair patterns follow the design more than the badge. Single-stage condensers mostly need capacitors, contactors and fan motors, which are cheap and common. Variable-speed units add an inverter drive board, and that part costs more to replace on either brand. Warranty terms differ slightly: Carrier gives 90 days to register and lets you choose 10 years of parts or 5 years of parts plus 3 of labor. Trane gives 60 days for its Registered Limited Warranty, typically 10 years on parts.
How should you compare Carrier and Trane quotes?
Get both quotes for the same staging, the same matched indoor coil and the same backup-heat plan, then compare. Installed prices in our area run $5,200–$9,800 for central AC and $7,500–$14,500 for a heat pump, and the staging moves the price far more than the brand does. Refrigerant charge, airflow setup and duct condition decide how well either brand performs in your house, and having a service company close by matters for the life of the system.
We service and repair both brands. If your current system is not keeping up, a service call is a $79 trip charge, waived when you approve the repair. Call 612-429-3465.
Questions
Will a Carrier or Trane heat pump keep my house warm at -20°F?
Their cold-climate models keep running that cold. Carrier lists heating operation down to -23°F on the Infinity 21 Ultimate Cold Climate, and Trane says its 20 TruComfort Cold Climate keeps operating to -20°F. Output drops as it gets colder, though, so in Minnesota we still pair them with a gas furnace or electric backup sized for the design day.
Is Greenspeed the same thing as TruComfort?
They are each brand's name for its variable-speed technology. Both let the compressor and outdoor fan run anywhere across a wide range instead of just on or off, which means long, quiet run times and better moisture removal in July. The exact low end of the range varies by model, so compare the spec sheets for the size you are quoted.
Can I add a Carrier or Trane heat pump to my existing furnace?
Often, yes. That setup is called dual fuel: the heat pump carries mild weather and the furnace takes over in deep cold. The indoor coil has to match the new outdoor unit, and the furnace blower has to move enough air for it. With the communicating top tiers, the furnace and thermostat generally need to be the same brand as the outdoor unit.
What refrigerant do new Carrier and Trane units use?
Both now build their residential split systems on R-454B, which Carrier sells under the name Puron Advance. If you have an R-410A system, it can still be repaired and recharged. A new R-454B outdoor unit needs an indoor coil rated for that refrigerant, which is why we quote a matched coil with most replacements.
Do you service Carrier and Trane air conditioners?
Yes, both brands, including their variable-speed and communicating models. A service call is a $79 trip charge, waived when you approve the repair, and you get a written, flat-rate price before we start. We are open 7 days a week, 7am to 9pm. Call 612-429-3465.
