Carrier® Expertise

Willis Carrier invented air conditioning in 1902. Over 100 years later, Carrier continues to be on the forefront of leading edge innovation and unsurpassed standards of excellence with the Infinity® system and advanced technologies such as Greenspeed™ intelligence, Comfort Heat Technology® feature and Ideal Humidity System® technology. Carrier’s engineers and dealers strive to provide homeowners with the most innovative indoor comfort solutions available.

  • Carrier has one of the most extensive product testing facilities in the world to ensure one of the lowest failure rates in the industry.
  • Carrier maintains one of the industry’s toughest reliability testing standards to be sure that every product will provide trusted indoor comfort and performance for years.
  • During the design phase, hand-built prototypes are tested to maximize performance levels.
  • Production-line test stations provide quality control during assembly. Then, a bank of computers test each product to ensure performance.

Matching Components Provide Optimum Comfort, Efficiency and Performance

  • The Infinity® system by Carrier is our most advanced system, connecting the best components for the ultimate home comfort control.
  • Forced-air systems are usually built around an indoor unit, such as a furnace or a fan coil.
  • The outdoor unit, an air conditioner or heat pump, is matched with a furnace or fan coil for year-round comfort.
  • Air quality is greatly enhanced with the addition of an air cleaner, humidifier and a ventilator.
  • Precise temperature control comes from a Carrier® thermostat which is matched to your specific system.
  • Zoning provides the ultimate control for true custom comfort.

Things to Consider Before You Buy a Heating and Cooling System

1. Efficiency

Efficiency ratings are like gas mileage – the higher the rating, the more efficient the product. All products are given the following ratings, so you’ll know exactly what to expect from your investment.

AFUE (Annual Fuel Utilization Efficiency)

This measurement gauges heating fuel usage. The Infinity® 98 gas furnace receives up to 98.5% AFUE.

HSPF (Heating Seasonal Performance Factor)

This measurement gauges the heating mode of heat pumps. Most new units have ratings from 7.0 to 9.4. The Infinity® 20 heat pump receives up to 13.0 HSPF.

SEER (Seasonal Energy Efficiency Ratio)

This measurement gauges air conditioning cooling. The Infinity® 21 air conditioner receives up to 21.0 SEER.


Carrier Corporation has determined that certain products meet ENERGY STAR guidelines for energy efficiency. Look for this logo on our Infinity® and Performance™ Series products.

2. Puron® Refrigerant

Puron® Refrigerant

Carrier was the first to introduce a new, non-ozone depleting refrigerant called Puron® refrigerant – a full six years ahead of the competition – paving the way for the future. Puron refrigerant is chlorine-free, so it doesn’t damage the Earth’s ozone layer. And, as other refrigerants become less available, Puron refrigerant will be the refrigerant of choice for years to come.

3. Comfort

Carrier specializes in creating a customized home comfort system with our broad selection of heating and cooling products. Your Carrier® dealer can help you choose the best system for your home including Carrier-exclusive features that further enhance your indoor environment.

Greenspeed™ Intelligence

Greenspeed™ Intelligence

Greenspeed™ intelligence is our unmatched technology that takes into account your complete comfort, from degrees to dollars to decibels. It marries adaptable-speed technology with Infinity® intelligence to deliver precise comfort, constantly matching to the comfort demands of the home. This translates into reduced energy use and reduced temperature swings throughout the home.

Comfort Heat Technology® Feature

Comfort Heat

The Comfort Heat Technology® feature accurately predicts the need for heating while cutting temperature swings in half, and provides a nearly continuous flow of warmth in low-capacity operation for a steadier, more consistent indoor temperature.

Infinity® System

When a heat pump or air conditioner and Carrier® humidifier are combined with a variable-speed furnace or fan coil and the Infinity® Touch Control, the revolutionary Infinity system allows you to control temperature, humidity, air quality, fan speed and ventilation. It even detects when your air filter needs replacing. It’s so advanced it automatically adjusts to your systems’ needs for peak efficiency and performance. It’s the ultimate control center for all of your home system components.

Ideal Humidity System® Technology

Ideal Humidity System

Ideal Humidity System® technology automatically adds or removes just the right amount of moisture to keep your home comfortable. Ideal Humidity System technology can help you save on energy costs, too. When the humidity is right, you can feel comfortable at higher temperatures in the summer and lower temperatures in the winter.

4. Sound

Home comfort shouldn’t come at your ears’ expense. That’s why quiet is built right into every system. Carrier® furnaces feature the QuieTech™ noise reduction system that provides comfortable heat while generating very little noise in the process.

Carrier ® air conditioners are also quiet, thanks to the exclusive Silencer™System that ensures extra-quiet performance by maximizing airflow while minimizing vibration.

5. HYBRID HEAT® Systems

Hybrid Heat

With both a heat pump and a furnace, Carrier’s HYBRID HEAT® system will keep you comfortable throughout every season. The heat pump is designed to work like an air conditioner during the warmer months, transferring heat from inside your home and sending it outside. As the seasons change, the heat pump reverses this process by extracting heat from outdoor air and moving it into your home. By combining an electric heat pump and a gas furnace, our HYBRID HEAT system delivers big comfort while using less energy. Ask your dealer if a HYBRID HEAT system is right for you.
