Duct Design and Sizing
Duct work is designed according to ACCA Manual-D standards. Installed per Arkansas Mechanical Code. Each installation layout is custom sized to the home's requirements.
In our applications, we generally use sheet metal duct work, and we insulate the duct with R-8 duct insulation (Code only requires R-6). This does cost more than commonly used "flex duct", however this saves you, the homeowner, and provides better comfort throughout the home.
If your air conditioner or heat pump fails in the middle of summer and you get hot, there are a number of things that may have caused that. One very common issue we see often is refrigerant (Freon) leaks. Typically this is the result of formicary corrosion on the indoor coil/evaporator coil. We don't do any guess work though. We introduce a dye into the refrigeration circuit and use UV glasses to verify the location of the leak.
