Tempstar vs Carrier: Energy Efficient/SEER Rating

Reviews on Tempstar air conditioners note how the air conditioning is energy efficient. The Tempstar furnace, cooling system, heat exchanger, or heat pump have high SEER. With Tempstar air conditioners, energy bills reduce. Especially the Tempstar furnace and air handler.

Tempstar’s premium line models come with SEER ratings of between 15 and 19. The TVA9 Tempstar model has a 19 SEER rating, the best.

And in the value line models of Tempstar, there’re units with up to 16 SEER ratings. And the NH4A4 compact and stackable model leads the line with a 16 SEER rating.

Carrier’s energy-efficient air conditioning systems can help reduce energy costs. And increase the comfort of your home or office.

How do you know whether a Carrier® air conditioner is one of the most efficient? First, look for the Energy Star® symbol. It signifies that the system meets or exceeds efficiency guidelines.

Carrier offers a complete line of ENERGY STAR®-qualified air conditioners. And standard products. Their Infinity 20 AC unit with Greenspeed™ intelligence offers up to 21 SEER cooling. And you can pair it with an Infinity gas furnace for a complete high-efficiency system.

The Infinity 19VS variable-speed heat pump offers up to 19 SEER efficiency. And is also AHRI-certified and listed as Energy Star Most Efficient 2016.

Here are the variable speed air handler pros and cons if you choose to go with them

Tempstar vs Carrier: Compressor Options


Single-stage operation

Tempstar’s single-stage compressor offers one level of cooling output. Single-stage systems operate at 100% capacity sometimes.

Two-stage operation

A two-stage compressor offers two levels of cooling output. High for warm summer days. And low for gentle days and nights. The system runs at 80% capacity in a two-stage operation 80% of the time. Hence, offering more consistent comfort and humidity control. 

Variable speed operation

A Tempstar variable speed compressor offers three levels of cooling output. High for hot summer days, medium for milder weather when you want to reduce indoor humidity. And low for milder weather when you want to maintain a constant temperature.


Carrier offers scroll/variable speed compressors for the best cooling performance and efficiency. These compressors can adjust their capacity as necessary to meet the system demands. Thus, reducing energy usage and improving efficiency

The scroll compressor is in Carrier’s Comfort Series packaged air conditioners.

Tempstar vs Carrier: Condenser Fan Options


1. Constant Torque ECM Motor Fan:

Constant torque motors run when the application calls for a high-efficiency motor. Moreover, it can deliver high performance over various operating conditions.

2. Standard PSC Motor Fan:

PSC stands for the permanent split capacitor. The PSC motor uses a run capacitor to maintain two windings at different voltages.

3. Variable Speed Motor Fan:

Depending on the system’s needs, they can operate at multiple speeds within a given range.


The fan options available for Carrier condenser air conditioners include

Single-stage, dual-stage and multi-stage condensers. In a single-stage unit, the fan pulls in cool outside air. And passes it through the coils. And blows hot air out the top of the unit. 

There are at least three stages in the evaporator in a multi-stage unit. The primary function of each stage is to remove heat from incoming air.

Tempstar vs Carrier: Heating Options


Tempstar offers several air conditioners, furnaces, and heat pumps for residential use. The company also has a line of high-efficiency products.

Tempstar offers five tiers of furnaces, ranging in efficiency from 80 AFUE to 98 AFUE. The company also has a line of furnaces that are Energy Star certified.

Tempstar offers three tiers of heat pumps, ranging in efficiency from 14.5 to 19.5 SEER and up to 8 HSPF.


As a homeowner, Carrier HVAC systems can provide warm air. Instead of the units wasting away in the storage room, use them. That is, in the winter season. In some Carrier AC units, the compressors turn to heat pumps. The unit’s compressor applies negative pressure against the Puron. When that happens, it heats up, providing warmth.

Moreover, the Carrier system turns into a heater when cold air passes through the warm coils.

Tempstar vs Carrier: Noise Levels


The fan motor on the Tempstar air conditioner is designed to be quieter than other units. And according to Tempstar. The unit is equipped with a ton of insulation. And a thick, galvanized steel cabinet reduces noise levels and improves efficiency.

High-end and smallerTempstar AC models produce a maximum of 66dB noise. At the same time, other Tempstar models make 70dB+ noise.


Most Carrier air conditioners are quiet, registering at around 26 decibels. For reference, 30 decibels is about as loud as a whisper. While 40 decibels is equivalent to a quiet library. And 50 decibels is roughly the sound level of a normal conversation

Carrier offers some models with even lower noise levels. For example, the Infinity 21 24ANB1 and 24ANB7 have sound levels as low as 59 decibels. That’s quieter than most libraries. The Infinity ICS 16 2-ton split system’s outdoor unit is also tranquil at just 63 decibels.

Tempstar vs Carrier: Warranty


Tempstar offers its many customers no-hassle warranties. The warranties cover the entire HVAC unit. And parts like

  • Compressors
  • Coils
  • Heat exchangers

If a major component becomes faulty during the warranty period, they replace the unit.

Also, Tempstar offers

  • 10-year warranties on the high-level model units
  • 5-year warranties for average models
  • 1-3 year warranties that cover low-level models. Also, the furnace and furnaces.

However, Tempstar’s standard warranty covers the standard models. But not its no-hassle warranty.


They are known for their dependable and high-quality products. So, they offer 10-year parts limited warranty*. Unfortunately, the Carrier air conditioners warranty is broken into three parts:

  • Carrier Compressor Warranty: 10 years
  • Carrier Functional Parts Warranty: 10 years
  • Carrier Labor Warranty: 1-year

Tempstar vs Carrier: Tax Breaks


Each residential system qualifies for $300 or fewer tax rebates. But, for your unit to qualify

First, the unit should be new. And Energy Star rated. Refurbished or old HVAC systems don’t qualify.

Second, an HVAC pro should conduct the installation of your unit.

When the HVAC system satisfies the above criteria, apply for the tax credit. And that’s via the 5695 form or online.


Carrier HVAC brand has several models in its wing. But systems with a 16+ SEER rating qualify for the $300 rebate.

Bottom Line: Which Air Conditioner should you Choose?

So, why choose Tempstar?

  1. Reliable, Efficient Cooling

With efficiencies up to 18 SEER, you can enjoy cooler temperatures and lower utility bills. We design our air conditioners from top to bottom with reliability in mind.

  1. Environmentally Sound Refrigerant

Tempstar air conditioners use R-410A refrigerant – an EPA-recognized alternative to CFC refrigerants used in older systems. R-410A does not contribute to ozone depletion.

  1. Quiet Operation

We use a two-stage scroll compressor that operates at lower speeds much of the time. That means less noise and greater comfort.

So, why choose Carrier?

  • Carrier is ozone-friendly since it has the R-410A and R32 refrigerants
  • Inverter technology
  • Cooling coils
  • Intelligent alert system
  • Power-saving features
  • Ambient temperatures

Both Carrier and Tempstar offer quality products. But it comes down to what suits you best at the end of the day. However, if we had to choose only one, we would go with the Carrier Infinity.
