How to Winterize Bryant Plus 90s
The Plus 90 is a natural gas-powered condensing furnace manufactured by Bryant, a heating and air conditioning company that has been in business for more than 100 years. The Plus 90 uses a dual heat exchanger system that extracts the maximum amount of heat for the fuel used. Bryant claims the Plus 90 produces 33 percent more heat than conventional heaters. If you have a second home and will be leaving your furnace unattended for several months, you should take steps to protect and winterize your unit. Does this Spark an idea?
