Thick dust filter
In general, air conditioning, heating effect is not good, partly because too much air filter dust, foreign bodies inside and outside the vents are blocked. The role of the adsorption filter dust in the air, if the plot without too much time cleaning the dust will block air circulation, resulting in the outlet of the air supply reduction, which resulted in flow of air inside the heating capacity can not be brought out in a timely manner, resulting in insufficient heat exchanger capacity, this is not failure, is the maintenance of air conditioning, just remove the air filter regularly cleaned, you can return to normal.
Lack of fluoride
Fluoride may also be missing one of the factors causing failure. Currently, most people use the heat pump type air conditioner or heat pump plus auxiliary heating. These two works are the use of evaporator coils freon evaporation absorbs heat from the outdoor air. When the outdoor temperature is lower, and the Freon evaporation temperature of the temperature difference is small, effect of heat transfer along with deterioration of hot air for less. Therefore, if the old models, service life is longer, wear a larger compressor, when the outdoor temperature is below 0 ℃, air conditioning, the heating effect is hard to be satisfied. In addition, if their own air-conditioning installation at the nut brass horn is loose, or have moved over machines, the problem is most likely caused by lack of fluoride. In addition, the line control problems is also more common. For example, if the machine does not work outside, most of the capacitance, temperature probe or a motherboard failure.
Other reasons
Many people may wonder, good air conditioning in summer is also used, how one winter to die? In fact, condenser coils, refrigeration and heating components are separate, so the cooling function is normal, while the heating is not normal, the problem may be that in the four-way solenoid valve or the control circuit, it is possible for the electric heater and power supply AC contactor circuit, over-temperature thermostat and fuse failures, these failures need air conditioning manufacturers maintenance personnel, or professional mechanic can only be determined after site inspection.
