Matching components provide optimum comfort, effiecency, and performance.

1. Efficiency
Efficiency ratings are like gas mileage-the higher the rating, the more efficient the product is.All products are given the following ratings, so you'll know exactly what to expect.

AFUE
(Annual Fuel Utilization Efficiency)
This measurement gauges heating fuel usage. The Infinity© 96 gas furnace receives up to 96.6% 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© 17 heat pump receives up to 9.5 HSPF.

SEER
(Seasonal Energy Efficiency Ratio)
This measurement gauges air conditioning cooling. All new models are required to have atleast a 13.0 SEER rating. The Infinity© 17 heat pump receives up to 21.0 SEER.
For every $100 you would spend to cool your home using a 10.0 SEER system, the Infinity© 21 air conditioner with 21.0 SEER would save you almost $52. Actual savings will depend on the efficiency of your current system compared to the efficiency of a new system.

Energy Star©
Carrier Corporation has determined that certain products meet ENERGY STAR© guidelines for energy efficiency. Look for this logo on Carrier products.

2. Refrigerant
Freon©-22 Refrigerant
Since its debut in 1930, Freon© refrigerant has been used in cooling systems. And while it's still available, the Clean Air Act of 1990 prohibits the production of Freon-22-based air conditioners and heat pumps by 2010, and Freon-22 production by 2020. As Freon-22 production declines, its cost is predicted to rise.

Puron© Refrigerant
Carrier was the first to introduce a new, non-ozone-depleting refrigerant called Puron©--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 (Kingsport Heating and Air) can help you choose the best system for your home including Carrier-exclusive features that further enhance your indoor enviroment.

ComfortHeat© Technology
ComfortHeat© Technology 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.

Infinty© System
When a heat pump or air conditioner is combined with a variable-speed furnace or fan coil, the revolutionary Infinty© System is the only system in the industry that allows you to control temperature, humidity, air quality, fan speed, and ventilation; and 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.

IdealHumidity© Systems
IdealHumidity© Systems automatically add or remove just the right amount of moisture to keep your home comfortable. IdealHumidity Systems can help you save on energy costs too. When humidity is right, you can feel comfortable at higher temperatures in the summer, and lower tempreatures in the winter.

Hybrid Heat©
Carrier's Hybrid Heat© delivers peace of mind to homeowners concerned about the unpredictable nature of utility costs. Hybrid Heat pairs a gas furnace with an electric heat pump to provide comfort, economy, and flexibility. Your Carrier Hybrid Heat system will automatically switch between electric and gas heating as needed to keep your home comfortable all winter long while optimizing the efficiencies of each fuel source.

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.
Carrier air conditioners are also quiet, thanks to the exclusive Silencer System© that ensures extra-quiet performance by maximizing airflow while minimizing vibration. With sound ratings as low as 70 decibels, Carrier's Infinity Series air conditioners are as quiet as a refrigerator.
