I installed a new Heil N4H348 (4 ton conden It can be frustrating to turn on your air conditioner (AC) then suddenly notice that it is not cooling to your set temperature. If you can't go below 78 or 77 degrees it's probably because you have an air exchanger turned on. Other possible causes include, dirty air filters, leaky ducts, excessive outdoor temperatures, leaky refrigerant and ...This would typically cause a low suction pressure and a low superheat. In heat mode, a dirty air filter causes low airflow across the condenser. This can cause extremely high head pressure. In heat mode, a dirty outdoor coil can cause a low suction pressure. As an example, Trane includes a pressure curve chart with many heat pump condensing units. Your inability to operate the equipment at 40°...
