In New York, NY, we handled an appliance installation job for a client whose two window air conditioning units had been removed and stored over the winter months and needed to go back in before warmer weather arrived. Before we started, one bedroom window sat bare beside an exposed pipe running from floor to ceiling, and a second small bedroom had only a curtain covering the opening where a unit used to be. Both windows were ready for the units to go back in, just waiting on the work, and we arrived at the agreed time to begin the reinstallation. We seated each window air conditioner back into its window opening, leveled it, and secured it in place. The units were fitted into the deep window sills with white accordion-style side panels locked in on each side, sealing the gap and positioned so they would drain correctly to the exterior. We confirmed the electrical connections and tested both installs before leaving. Both units were seated cleanly, with no gaps and no filler needed. Window AC installation in apartments across New York City looks simple but has real consequences if it's not done right. The finished result in this New York, NY apartment was two window air conditioners reinstalled and ready for the season, sitting cleanly in their window openings with the side panels in place.
