Save Now, Save Later Bryant's model 633A cools your home and saves money at the same time with 12 SEER (Seasonal Energy Efficiency Ratio) and up to 8.3 HSPF (Heating Seasonal Performance Factor) efficiency. Those ratings easily surpass those of older heat pumps as well as a considerable number of current products. And, as traditional refrigerants become scarce, you will avoid the rising costs of servicing heat pumps using those refrigerants because Puron will remain in production and available for a reasonable price. 1. Enviornmentally Sound Operation & Future Savings Are two of the benefits of using Puron refrigerant. You'll enjoy home comfort year round without harming the Earth's ozone layer now, and avoid the potentially higher costs of maintaining or servicing products using Freon-22 later. 2. Money-Saving Economy  Means home comfort that's easy on the utility bills, thanks to the extra-efficient scroll compressor designed specifically for use with Puron refrigerant. 3. Trusted Reliability Is a Bryant trademark that continues with the model 633A. High and low pressure switches provide compressor protection against damage from extreme conditions. 4. Performance You Can Count On Is the result of Bryant's discharge temperature switch, which protects the compressor from overheating. Lasting Comfort Is encouraged with the system protection offered by our filter drier. This component removes moisture or contaminants that can harm your air conditioner. (Not Shown)
