    Q:When I turn on the unit for heat, the vents open but no heat comes out. After a delay I get error 19. I returned the last unit because it always showed an error 19. What do I do to get rid of this error and make the heat work? What could be causing?

      Two years in and this thing is garbage.
      We paid a company to install this unit two years ago. It worked when first installed. The remote and icons are junk. They don’t really have good explanations for the different modes. It uses the remote for everything and the batteries don’t last long. We had to pay to get this unit serviced this year, because the Freon was low and it wasn’t cooling. Now the temperatures have dropped and it isn’t heating. If I could go back in time, I would not have bought this unit.

        Pretty basic to install. Except where I installed it, I couldn't go straight through the wall, had to run the piping 4' to the left and come down to the unit

        So far so good. Installation was easy. I was concerned if this was big enough for my garage. It’s 1000sqft with 9’ ceilings and insulated. I can get it down below 80 inside on 100 deg Oklahoma days. It feels cooler than it is because it removes the humidity from the air. Very pleased so far!

        Couldn’t be happier
        I installed this today in a 12x20 she shed. Cooled down to 68 quickly and runs very smoothly. Installation wasn’t a problem but I have years of experience and all the tools. Hopefully we get good life out of it but only time will tell as we all know how todays appliances are.

          excellent value for the money
          Unit was in stock and well packaged. Included lineset and control cable, remote control. Instructions were adequate for the most part. Installed in about 6 hours with some specialty tools required (vacuum pump, vacuum gauge, R410 core removal tool, crescent torque wrench, flare tool) to do the install properly. Had previously installed units from Mitsubishi and Daikin and the Hessaire seemed to be constructed to a similar level of quality. Will have to wait and see about the durability.

            Install was a little tricky. However the directions were great. Definitely a 2 person job. It takes about 30 to cool 3 car garage from 90 to 75. It has kept me cool even on those hot Saint Louis days. Good deal.

            Don't bother
            If I could, I would hit this product with a truck, throw it over a bridge and sink it in the ocean. It would work just as well as it does now. I have owned this for over a year and have paid for it twice with the repairs it has needed. Find a brand that is locally supported by professionals.
