“We have metal drain pans in stock, however, they have 4 vertical sides, so you would have to modify them. You can purchase the 32” x 36” tray and use metal snips to remove one of the slides. https://hvacdirect.com/drain-pan-32-x-36-dp32x36w.html
Then you could slide the ‘open’ edge under the heat pump, and your sloping porch would collect the condensation at the low side. You could then attach PVC to the lower corner to drain water away to a safe drain location. As long as the drain remains clear, this should protect your porch boards.”
If you have any further questions please feel free to give us a call! Thanks.
