The 3.5 Ton Variable Speed MrCool Signature Central Air Handler is built to help extend the life of your Central Split System. This air handler is magnificently efficient at cooling or heating your home, with its variable-speed function preventing costly, substantial changes in temperature.
Rather than working at full blast to change the air temperature quickly and then shutting down completely, this air handler maintains a consistent low speed. This ensures that keeping your home at your ideal temperature never requires energy-wasting shifts in function. As a result, your entire Central Split System experiences less damaging stress—so that it can keep running for years to come.
Not only does the Variable Speed MrCool Signature Central Air Handler reduce wear-and-tear to your HVAC system, but it also provides a better daily experience for you and your family. The low speed of the air handler means that its soft operating noise fades into the background of your day. Plus, the temperature won't fluctuate every few hours. Once you find a temperature that works for you, you can set it and forget it.
Because this air handler works at variable speed, it can make automatic, small adjustments to account for the air needs in every room of your home. For example, if the temperature outside gets suddenly cooler as a storm approaches, this air handler will adjust the airflow to ensure the air inside doesn't change.
Investing in a quality air handler means you make the most out of your Central Split System while improving the air quality in your home, maintaining a perfectly consistent temperature in every room, and reducing expensive energy waste.
