Air Conditioning Repair: AC Runs but No Cold Air


It’s a common air conditioning problem: the AC runs but there’s no cold air. We see this issue all the time, and it’s a serious problem with the heat we experience here in Miami. If your AC is running, but the air isn’t cold, you need to get it dealt with as quickly as possible. What are some of the causes?

In many cases, the lack of cold air stems from a refrigerant leak. Your air conditioner relies on refrigerant to facilitate the cooling process, and indeed needs a specific amount of refrigerant (the exact amount depends on the model of your air conditioner) in order to function. When it leaks, those levels drop, along with the cooling capacity of your unit. Ice usually forms on the evaporator coils, which further insulates the air you need to cool from the refrigerant charged with doing the job. An expert service technician can seal the leak and recharge refrigerant to the proper level.

In some cases, the issue lies not with the levels of refrigerant, but with the condenser, which reverts the refrigerant to liquid form as a part of the cooling process. If it malfunctions, then the air conditioner won’t function simply because there won’t be enough liquid refrigerant to return to gaseous form in the evaporator coil (which pulls heat from the surrounding air, which is then is distributed throughout your home). These cases tend to be more expensive than lower refrigerant levels, since the condenser itself will likely need to be replaced.

In any event, there are a number of possible causes of this problem: if the AC runs, but no cold air comes out, you need a trained expert to hunt down the cause and fix it. In Miami, air conditioning repair can be provided by the experts at Air On Demand.
