Common AC Problems To Address Before Summer
Spring has sprung and you might probably think that it won’t be for a few months that you’ll have to think about or obsess over the condition of your business (that is if your shop is still open) or home ac units, perhaps ignoring common AC problems. But with climate change happening (don’t be a denier!), it might be wise to think about family heating and cooling issues. Besides, you wouldn’t want to be thinking of ac service options when it’s already summer and your home or business is already plagued with air conditioner concerns. That would already be too late! So, having a general idea about common ac problems is always a good idea so that nothing would blindside you and you’ll know what steps to take when consulting an air conditioning service to help you.
Problem: Evaporator coils that have frozen.
Your ac unit contains evaporator coils that act like sponges that absorb heat from the air. These coils that contain refrigerant actually function properly when there is warm air circulating around them. Sounds ironic, for a system that functions as a cooler of air to require warm air for it to do its job, right? But that’s how ac units work, and when there is something wrong with how the air circulates in your ac unit which in turn causes these evaporator coils to get too cold, thin layers of ice can start to form. When that happens, the coils will freeze as there is no warm air getting to them, which impedes their function, so you’ll get warm air coming out of your ac if any air at all.
When is the last time you cleaned or replaced your AC filters? Dirty air filters may negatively impact the airflow in your central air conditioning system. As a result, moisture in your system won’t be able to settle on the coils properly. This issue will cause the the coils in your central air conditioning system to become frozen and will negatively impact the efficiency of your system.
Problem: Not much refrigerant.
As mentioned earlier, the evaporator coils in your ac contain refrigerant that functions as the sponge that removes the humidity and heat from the warm air they absorb. The challenge with refrigerants is if your unit develops leaks in the lines where the refrigerant is, and when the refrigerant leaks, there may not be enough of it in your ac unit to make it function effectively. Thus, even if air conditioning repair folks will replace the lost refrigerant, they will still need to do more to really fix the problem, such as finding the leaks and repairing them so that the refrigerant won’t be escaping any holes anymore. Be warned: This process may take time, especially when there is more than one hole or leak where the refrigerant is leaking from.
There is no way to check the charge of refrigerant in your air conditioning system without a licensed technician, but there are definitely signs that you should get your system checked.
Problem: Consider coils that have accumulated dirt.
If you were made aware of the evaporator coils and refrigerants earlier, let me divert your attention now to another part of your ac unit – the condenser coils. If the evaporate coils absorb hot air with their refrigerants, what the condenser coils do is dispose of the heat that the refrigerants take out by expelling them outside your structure. The sad thing about condenser coils though, is that they also tend to attract dirt, dust, and soot, and when they get covered, the heat they are supposed to remove gets trapped in the unit instead of being expelled. Thus, your ac unit has to work double-time, with its parts subject to increased wear and tear.
Your condenser unit is located outside, which exposes it to all kinds of surrounding dirt and debris. Although your condenser unit is designed to defend its interior coils from getting dirty, some debris inevitably makes its way inside and builds up on the coils over time.
