Question about Coleman Propane Forced Air Heater w/Electronic Ignition (50,000-80,000 BTU)
Start with making sure you have aclean filter, after that make sure the blower speed is at the proper setting when the air conditioning is on---usually either high or medium high for a fixed speed system, make sure the return air vents are not blocked or restricted as well as the delivery vents not close or restricted to cause too much static pressure ( back pressure at the delivery side can reduce air flow across the a-coil ) also make sure the insulation sheet that is usually above the a-coil is not being blown down across the a-coil entryside when the blower is on. After checking all these, if you find nothing you should start by having the pressure checked --- basically comparing the pressure at the "outside unit" to the pressure at the "inside unit" or a-coil. these are high side and low side pressures. Have you done anything else to the house----attic vents, new soffits, insulation, etc that may be affecting heat gain in the house.Is it a house, mobile home or what?
