What Are Some Of The Common Reasons Residential Air Conditioners Malfunction?

To stay cool during the summer months, you'll need to keep your residential air conditioner running smoothly. Problems leading to air conditioning system malfunction can happen at any time, making your interior living space unbearably hot and uncomfortable.

The good news is that most problems that cause AC failure can be repaired by an experienced HVAC technician. Keep reading to learn about the various problems that are often found when repairing air conditioning equipment.

Forgetting To Change Your Air Filter

As a rule of thumb, you should change your HVAC system's air filters after every three months. If you're aware of more pollutants in the air circulating within your home, you should change the air filters even more frequently.

So, what happens if life happens and you don't change your air filters on time?

You'll experience poorer indoor air quality, and your home will inadvertently become dirtier due to the increased amount of dirt circulating throughout it. But perhaps the most obvious problem may be that your air conditioning system will start to operate inefficiently and cause your domestic utility bills to go up. Luckily, the problem requires an easy fix: removing and replacing dirty air filters with new ones. 

The Presence Of Refrigerant Leaks Within The System

The air conditioning systems in both cars and homes have one thing in common: they all require refrigerants to deliver cooling action. A refrigerant is a working fluid that facilitates the extraction of heat from an interior environment and its eventual transfer to the outside environment, leaving people feeling cooler in hot weather.

While this fluid chemical isn't designed to escape from your home's AC system, it's not uncommon for it to do so due to the presence of leaks within the system. When this happens, the system will lose its cooling power and start to blow hot instead of cold.

An HVAC specialist can check your AC refrigerant level and recharge the system if the refrigerant level is low. Before adding more refrigerant to the system, they'll detect and seal all leak spots to prevent the further loss of refrigerant.

Having A Dirty Air Conditioning System

Your AC system comprises various components, including the evaporator coils, condenser coils, compressor, coil fins, air ducts, air vents, and many more that need to be kept clean and obstruction-free to ensure effective and efficient cooling performance.

Not cleaning both the indoor and outdoor units of the system often enough may result in too much dirt building up on vital components. This can create problems for the system, thus resulting in inadequate cooling and operating inefficiencies with the system.

The major problem with having a dirty AC system is that by the time AC failure occurs, you may have to repair or replace various components of the cooling system to get it running again.

No matter the reason your residential AC system may fail, an HVAC technician can help to fix the problem and restore your home's thermal comfort.
