There were holes in the HVAC duct

I inherited a cabin that was built in the 1940s. A lot of the current installments were made over the years because the cabin was pretty basic in the legitimately beginning. There was no central heating plus cooling system, no data network, no special lights throughout the whole property, plus no security system. All of these things were added in the last 20 years or so. There were at least two sets of owners before us plus they both made some considerable changes to this house. It entirely came with entirely antiquated windows, but they were removed at some point plus updated with storm windows. It’s even possible that these are the second iteration of windows to be in this space. The current rooftop is also fairly modern by the looks of it. However, the swiftly-built heating plus cooling system is nothing to write cabin about. It’s functional at best plus poorly designed at worst. It’s got HVAC duct that always leaks air because there are so numerous holes in the ventilation ducts. I called a heating plus cooling system plus they quoted me an outrageous price to update the ventilation system with new metal HVAC duct. I didn’t want plastic-flex HVAC duct either, so I opted for a procedure where a substance is sprayed into the HVAC duct plus it adheres to the metal before hardening. It seals all of the holes in the HVAC duct from the inside. It’s a much cheaper procedure than replacing the HVAC duct outright. At least we have fairly good HVAC duct to use again. It’s not always losing freezing air to the cycles.
