Why Is The air Conditioner Cooling Normally But Not Heating Properly?

In the cold winter, the heating of the air conditioner will bring us warmth. Many users will say my air conditioner can cool but why can't it heat? Confused everyone. When we test the air conditioner and the cooling is normal and cannot be heated, I hope that the solutions to these problems we encountered during maintenance can bring you a touch of warmth in the cold winter season.

Air conditioning capillary or check valve failure

Capillary: The capillary network simulates the mechanism of leaf veins and human capillaries, and the pipe network is composed of capillaries and main water supply and return pipes.

One-way valve: also known as check valve or check valve. Used in hydraulic systems to prevent reverse flow of oil flow, or used in pneumatic systems to prevent reverse flow of compressed air.

What to do if the air conditioner does not heat due to this reason: Replace the capillary or one-way valve to solve the problem that the air conditioner does not heat.

The outside temperature is too low

If the outdoor temperature is too low, the air conditioner will not work properly. Generally, the outdoor temperature is below zero, and the outdoor of the inverter air conditioner cannot be heated normally at about minus 15 degrees. Therefore, it may be that the outdoor temperature is too low, the air conditioner cannot defrost, and the air conditioner cannot heat .

What to do if the air conditioner does not heat due to this reason: Use tools to clean the frost on the air conditioner to solve the problem that the air conditioner does not heat.

Air conditioning four-way valve leaks

What should I do if the air conditioner does not heat due to this reason: Replacing the four-way valve can solve the problem that the air conditioner does not heat.

The filter is dusty

There is too much dust in the air filter of the air conditioner, and the ventilation openings of the internal and external units are blocked by foreign objects. The function of the filter screen is to absorb the dust in the air. If the accumulated dust is too much and not cleaned in time, it will block the air circulation, resulting in the reduction of the air output from the air outlet. Insufficient heating capacity.

What to do if the air conditioner does not heat due to this reason: Cleaning the filter can solve the problem that the air conditioner does not heat.

Fluorine deficiency in the air conditioner

The lack of fluorine in the air conditioner will not only prevent refrigeration, but also cause heating effects. At present, most air conditioners are heat pump type or heat pump plus auxiliary electric heating type air conditioner. The working principle of these two types of air conditioners is to absorb heat from the outdoor air when freon evaporates.

What should I do if the air conditioner does not heat due to this reason: ask professionals to add fluoride to solve the problem that the air conditioner does not heat.
