THE PROBLEM: During the middle of the summer heat, an 18-year-old HVAC system stopped providing air conditioning in a Doylestown, PA home, leaving the homeowner without reliable cooling when it was needed most. The existing Carrier heating and cooling system had served the home well for nearly two decades, but with the air conditioner no longer keeping the house comfortable, it was time to determine whether another repair made sense or if replacing the aging HVAC system was the better long-term solution.
