Carrier AC Unit Review 2022

Air conditioners provide relief from hot, humid temperatures. However, choosing an appropriate brand of air conditioner for your home can be complex, especially considering the vast array of brands marketing their units. 

This article reviews Carrier AC units, one of the HVAC industry’s most talked-about brands, to help you determine if their models are a suitable choice for your home. 

Who Owns Carrier Air Conditioner

United Technologies is Carrier’s parent company; they produce many heating and cooling products. 

Additionally, United Technologies Corporation owns Bryant and Payne and International Comfort Products, which itself owns a small group of companies, including ComfortMaker and Heil. 

As such, these brands are “sister companies.”

Is Carrier A Good Air Conditioner

Yes, Carrier manufactures good air conditioners. HVAC professionals and homeowners consistently rank them in the top three manufacturers of air conditioning systems. 

The systems are relatively affordable and efficient. Carrier’s entry-level models score well within the energy efficiency category, unlike many other brands whose models score considerably lower. 

Compared With Other Brands

Carrier ranks well compared to other brands, especially considering it continually ranks among the leading brands, year after year. 

All of Carrier’s products are ENERGY STAR certified, and the company regularly produces units with high-quality cooling capabilities with integrated power-saving features.

All of Carrier’s air conditioning units offer excellent humidity control, allowing the unit to remove up to 400% more moisture than most standard residential systems. 

Several of Carrier’s Infinity models feature an air purification system that inactivates 99% of specific airborne pathogens, including coronavirus and bacteria. 

Carrier vs. Rheem

Like Carrier, Rheem is also among the leading air conditioning brands. Rheem offers a reliable lineup of air conditioners at a competitive price and is considered an excellent brand for mid-range air conditioning units.

Carrier surpasses Rheem’s lineup in terms of energy efficiency, with Carrier’s top models rating up to 26 SEER. Rheem’s leading model offers ratings up to only 20.5 SEER. 

Carrier vs. Bryant

Carrier and Bryant are sister companies and share several similarities. Bryant offers a wide variety of air conditioning units to choose from, producing 17 central air conditioner models that top out at ratings of up to 26 SEER. 

Bryant products tend to be less expensive than Carrier’s units. However, most Bryant and Carrier air conditioners are made side-by-side at the same factory, with the only difference being the paint color and logo. 

Carrier Air Conditioner Models 

Many air conditioner brands divide their lineup into tiers that basically represent a good, better, and best product offering. Carrier is no different in this aspect, as they offer three levels. 

The Comfort Series consists of Carrier’s standard, entry-level models. These units are budget-friendly and feature efficiency ratings of up to 17 SEER. 

Carrier’s Performance Series consists of the enhanced, mid-tier lineup. These models seamlessly balance performance and cost, featuring additional controls and ratings of up to 17 SEER. Models with two-stage compressors also provide more even cooling in the home. 

Carrier’s premium lineup consists of the Infinity Series models. Units in this lineup have additional features for ultimate comfort management– meaning zero hot and cold spots in your home. They operate up to 50% quieter than competitors and boast ratings of up to 26 SEER.

Use the below table as a reference for how each model compares.

Carrier Air Conditioner Prices

Carrier air conditioning units tend to be a bit more expensive than other leading brands. Carrier AC unit costs are dependent on several factors, such as the specific model and size. However, Carrier might be the lowest-cost option depending on your local HVAC contractor. 

Generally, as the energy efficiency climbs (typically along with the tiers), the price does too. 

Occasionally, Carrier air conditioner rebates are available, sometimes up to $300 in rebates.

The below table shows the national average pricing for Carrier’s air conditioners.

What Size Air Conditioner Do I need?

 Air conditioning units are available in various sizes to suit numerous houses. Typically, you need about 20 BTU for each square foot of living space. However, high ceilings, large windows, wide doorways, and the like may cause that number to fluctuate. 

Use the chart below to help determine what size Carrier air conditioner you need for your home.

How Many Tons Is My Carrier Air Conditioner?

Determining the size of your Carrier air conditioning system isn’t a difficult task. Locate the data sticker, which should be on the side of the condenser, or outdoor unit. The 7th and 8th digits, occasionally the 8th and 9th, represent the size. 

You’ll see a number divisible by 6 or 12 representing the system’s rated BTU in thousands. A ton of air conditioning is equivalent to 12,000 BTU

For example, if you see the number 48, which is divisible by 12, equals 4, it means the system is 4 tons. 

Carrier Air Conditioner Problems

As with most things, Carrier air conditioning units may encounter problems from time to time. While some problems may be simple, such as using the reset button to reset the system, other issues might require professional assistance. When in doubt, call your local HVAC technician for help. 

If you have questions regarding your Carrier AC warranty, use Carrier’s website to check your warranty based on your serial number.  Ensure that you complete your unit’s registration with Carrier within 90 days of the original installation to receive the full warranty. 

Carrier AC Unit Not Turning On

If your Carrier AC unit refuses to turn on, a likely culprit is its power source. Check to see if the outdoor unit (or condenser) is running. 

Verify that the main power switch for the condenser is in the ON position, which is typically in a box mounted on the exterior of your home a few feet from the unit. 

If the switch is in the ON position, but the outdoor unit isn’t running, you have blown a fuse. Check the breaker box or fuse box for signs of a blown fuse or tripped breaker. Reset the circuit or replace the problematic fuse as necessary. 

Carrier AC Not Cooling

Several reasons could result in your Carrier residential AC unit failing to cool. Common problems include low refrigerant, a dirty air filter, and blocked return-air grilles. 

  • Blocked return-air grilles can cause your home to remain warm and unpleasant, which can become a problem, especially in older homes. Ensure that furniture, vases, picture frames, or other objects don’t block the airflow. 
  • Dirty filters are another common culprit that causes inadequate cooling. Buildup in the filter restricts airflow and will cause the unit to shut down. Look at the filter to ensure it isn’t clogged with dirt and dust. Generally, you need to replace 1-inch thick filters once per month and 2-inch or high-capacity pleated filters after longer stretches (check the filter’s label for the extract time). 
  • All air conditioning systems use refrigerant gas, which plays a vital role in cooling your home. It moves through copper tubing, the indoor evaporator coil, and the outdoor condensing unit in a continual, closed-loop cycle. The refrigerant pulls heat from your home as it moves through the indoor unit of the air conditioner, depositing it outside at the condenser and making the indoor air cooler and less humid. 

When refrigerant levels dip below normal, you may notice that your house isn’t staying cool, the system is running for longer than usual or turning on and off several times in a row (short-cycling).

After eliminating the possibility of incorrect thermostat settings and confirming the air filter is clean, the issue may fall to low refrigerant. However, if you suspect that the refrigerant is low, contact your local Carrier dealer. Refrigerant issues aren’t something you should or can troubleshoot yourself (unless you’re EPA-certified to check refrigerant levels). 

It’s best to have a qualified Carrier HVAC technician handle issues surrounding refrigerants. Additionally, if you have other problems with your Carrier AC unit that you cannot figure out, call an HVAC technician to help. They have the knowledge, skills, and tools to complete the necessary repairs.
