 They invested in a 10-year worry-free system. That's what I did. Now, the system that I had was a great one. And you know how long it had been going on, my AC downstairs? Since 2006. I got 18 years out of it. It's time for a change. This thing has no future, man. So that's what I did. I invested in a 10-year worry-free system. No charge for maintenance, parts, or labor for 10 full years. Set it and forget it. Heating and cooling.
