Went for a maintenance call today. Started at the furnace. Did a static pressure test, it was high. After adjusting the blower speed, it passed. Did a cubic feet per meter count, it passed. Temp split between the supply and return duct passed. Blower motor amperage passed. After analyzing the blower wheel, I noticed it was dirty. Changed filter due to being dirty. Outside unit got washed. The amperage for the compressor and the fan motor passed. The capacitor passed as well. Thank you for choosing LBA Services!
