Pittsburgh summers deliver high humidity that forces your air conditioner to remove gallons of moisture from indoor air every day. A typical 3-ton residential system pulls 2 to 4 gallons of water from the air during a 24-hour period in July. That water must drain away continuously through a half-inch PVC line. The humid climate also accelerates algae and mold growth inside drain lines and pans. Systems in Pittsburgh require more frequent drain line maintenance than drier climates. Many homes in older neighborhoods like Highland Park and Point Breeze have original HVAC installations from the 1980s with corroded drain pans and undersized drain lines that cannot handle the condensate volume modern high-efficiency systems produce.
We work with local building inspectors and understand Allegheny County requirements for condensate drain termination. Your drain line cannot discharge onto sidewalks where it creates ice in winter or slip hazards. It cannot drain against your foundation where it saturates soil and causes basement seepage. Our technicians route condensate lines to compliant discharge points and install proper air gaps when connecting to plumbing drains. We also understand the mechanical code requirements for overflow protection on attic air handlers, which many Pittsburgh homes have due to limited basement space in row houses and older construction.
