I just recently installed hvac system from swamp cooler. Was really expecting to have a freezing house at the push of a button. Unfortunately it's not working as I anticipated. When the installers were removing old furnace, they noticed that below it, instead of duct, was essentially concrete/cinderblock walling. My unit registers 42 degrees from the coils, so it's getting cold enough, however, when the air actually comes out of the vent it's up to 64! I believe we are losing a ton of efficiency here due to to there being no duct work and the cinderblock "ducts," not being sealed. Is there any simple fix or something that can essentially spray coat the entire duct area underneath my house to seal it and hopefully run my A/C more efficiently?
