I have a commercial building 5000 square feet with 18 ft cielings. No insulation just heavy layer black tar on roof.
Question. What happens to the evaporator if the system is to small to handle the heat load.
I told the customer he needed two 48,000 btu systems to handle one large area and one 4 ton system to handle the office area.
I insisted he was going to have problems.
He was having water filling up in the return air box and complained to me that I installed the system wrong and the systems run constantly. Then he told me that he was going to get someone else to finish the job.
I told him the water was forming because the Evap's were overloaded
Was I right or wrong!!
