There was a problem with the air duct

I’m not absolutely sure what is going on with our duct work despite the fact that I think that something is off. I have noticed that all the sudden I have had a giant spike in our heating and cooling bills and I cannot help but to suspect it is our air duct that is the culprit. The reason for this is because our air duct was determined to be weak heating and A/C guy out, he said there were particular sections of it that entirely should be updated because it wouldn’t be long before it started leaking and he warned that if it started leaking that I could have warm or frigid air escaping from our home and that was cost me more on our energy bills because our heating and A/C proposal would have to work much harder too he can cool our home. This is something else I had noticed too, even when I had the gas furnace all the way up on the control device it’s care about our new home will still be cold. It’s care about the gas furnace wasn’t working at all and at first I thought it was a problem with our oil furnace but I’m now starting to suppose the issue is honestly with our air duct. One way or the other, not tomorrow for sure because I have an appointment with the heating and AC company and they can tell me for sure. If it is our duct work that is causing the problem, I’m going to have it reseal and updated instantly. I’m already ready to schedule a air duct sealing
