Getting better HVAC results in the first floor condos versus the top

I really love my condo after four years of living here.

The location is just a walk from the beach, and everything from the kitchens to the bathrooms was remodelled right before I purchased it.

The stonework done in the master bathroom shower is simply stunning, with cuts of marbled red and pink stone intricately inlaid in beautifully complex, geometric patterns. To this day, I find myself staring at varying cuts of stone as I shower in the mornings and evenings. One of my closest friends visited my condo for the first time about a year ago and was absolutely blown away by the location and the interior. She was searching for a house and diverted to scouring the building for available units after she fell in love with mine. Although I bought the last ground floor unit, she eventually found a condominium on the fifth floor at a cheaper rate. There were two immediate caveats: one, the condo is on the top floor and the elevator ride is annoyingly slow; and two, the whole interior is original back to when the building was finished in the 1980s. All of the kitchen cabinets are original, all of the appliances short of the fridge and dishwasher are original, and the old matted carpets have stayed in place since day one. But the real kicker here is the terrible HVAC performance. Even though her central air conditioner, furnace, and ductwork had been replaced four years before, her performance wasn’t like mine on the bottom floor. We were told by an HVAC technician that the insulation from sunlight and heat was worse up at the top level compared to my unit that sits under four stories and is mostly surrounded by other condos as well. The building creates natural insulation that can’t be replicated on the top floor that sits right below the rooftop in direct sunlight.
