Joe and his assistant arrived on time for the job. Joe went above and beyond in explaining to me the process on how the duct sealing works. It took about 2 hours to prep, seal and clean up. I called joe because I believed the I did everything I can to balance the house’s air flow and temperatures. After a few hours we already felt the difference as the two back rooms seems to be warmer than before. Installed a thermostat in the two rooms and to my surprise the result was within 0.5 degrees from the rest of the house. This is money well spent. I recommend that you hire Joe to seal your ducts if you you are experiencing unbalanced temperatures in your house.
