Mitsubishi Ductless AC Replacement in Boathouse Row, Philadelphia Following Flood Damage

PROBLEM: The air conditioning units outside Fairmount Rowing Association along Boathouse Row, Philadelphia were damaged during Hurricane Ida's massive flooding. As a result, the boathouse was left with no AC and therefore needed a new solution for their cooling needs.

SOLUTION: ECI Comfort replaced the five indoor ductless air handlers with brand new Mitsubishi ductless models. The five new outdoor units were relocated to the opposite side of the building where flooding is less likely. They were also mounted high on the wall instead of the ground so that they will not be reached in the event of another flood.

Yardley, PA Addition Turns to Mitsubishi Ductless System

PROBLEM: Our homeowner in Yardley was putting an addition on the back of his house and basement with a contractor we have previously worked with. The rest of the house has a ducted heating and cooling system, but the new space was left unconditioned, meaning he needed a heating and cooling solution for these two new zones.

SOLUTION: ECI Comfort installed a Mitsubishi Ductless Hyper-Heat Mini-Split system. This system doesn't require ductwork to add both air conditioning and heating, so it's the perfect way to solve heating and cooling problems in a space without an existing system. Plus, it provides additional zones for spaces that have different comfort needs.
