What is the most common AC problem?
If your AC is not cooling like it used to, you are not alone. Pflugerville homeowners deal with this issue every single summer, especially once the Texas heat turns ruthless. But before you panic or assume your system is dying, you should know something very important. The most common AC problem is actually simple, extremely common, and completely preventable.
The number one issue we see at Altruistic AC Heating & Plumbing is restricted airflow caused by a dirty or clogged air filter. When your AC cannot breathe, it cannot cool. Poor airflow is the silent killer of comfort, efficiency, and equipment life. The good news is that once you understand why this happens and why it matters, you can avoid most cooling problems with professional care.
Let’s walk through why this issue is so common, what it does to your system, and why choosing Altruistic AC Heating & Plumbing is the smartest move you can make to protect your home.
Why Restricted Airflow Causes So Many AC Problems
Your AC depends on a steady flow of air to move heat out of your home. When the filter becomes clogged with dust, debris, or pet hair, that airflow drops. Once that happens, the entire cooling system begins to struggle.
Here is what restricted airflow does to your AC:
It causes your evaporator coil to freeze
Without steady warm air passing over it, the coil becomes too cold and forms ice. A frozen coil reduces cooling, weakens airflow, and often causes the system to shut off.
It forces your AC to run longer
Since your system cannot cool efficiently, it runs and runs. That extra run time spikes your utility bill and strains your components.
It overheats critical parts
Blower motors, compressors, and capacitors work much harder when airflow drops. This leads to burned components and unexpected breakdowns.
It reduces your comfort levels
Even if the system does not fail completely, cooling becomes inconsistent. Some rooms feel warm, others feel sticky, and the entire house feels off.
This is why Altruistic AC Heating & Plumbing always checks airflow first. It is the core of a healthy cooling system and the root of most performance issues.
Other Common AC Problems We See in Pflugerville
While a dirty filter is the champion of AC trouble, it is not the only reason your system stops cooling. Our technicians repair these issues every day throughout Central Texas.
Low Refrigerant
Refrigerant does not evaporate or get used up. If it is low, there is a leak somewhere in the system. Low refrigerant causes weak cooling, frozen coils, and long run cycles.
Dirty Condenser Coils
Your outdoor unit is exposed to dirt, grass, dust, and debris. Dirty coils cannot release heat, so your AC works twice as hard for half the results.
Clogged Condensate Drains
Texas humidity creates a lot of moisture inside your AC. When the drain line clogs, water backs up and causes leaks or safety shutoffs.
Thermostat Problems
Sometimes the thermostat is the real issue. Faulty sensors or aging thermostats can cause constant cycling or a system that will not turn on.
Electrical Failures
Capacitors, contactors, and wiring can fail under intense heat. Electrical issues are extremely common in summer when systems run nonstop.
These problems are avoidable when you have a professional HVAC team maintaining your system each year.
