Historic Philadelphia Home Heating & Cooling with a Unico High-Velocity HVAC System
PROBLEM: Eliza relied on window air conditioning units to stay comfortable during the summer months. However, they were inefficient, noisy, and unable to provide consistent, whole-home comfort.
SOLUTION: Having worked with ECI in the past, Eliza reached out to our owner, Ron, whom she had trusted on previous projects. Ron sent our project manager Matt to assess her home and finalize the heating and cooling system she had always wanted.
