Air conditioners are complex systems composed of electrical and mechanical components that work together to make cooling our homes possible. One of the most important components is the compressor, which pressurizes and circulates refrigerant throughout the system. When leaks, wear, or electrical issues cause the compressor to malfunction, your air conditioner can’t cool your home properly, leaving you sweating as temperatures rise in Colorado Springs.
Discover how this important component works, the top causes of AC compressor failure, and signs it’s time to call our experts at One Source Home Services for repair.
Understanding the Role of the AC Compressor
Air compressors are the heart of the air conditioning system. Without them, you wouldn’t be able to keep your home at a comfortable temperature.
The compressor’s main role is to condense the refrigerant fluid into a gas, which then moves through the rest of the system to cool the air. This process is vital to the cooling process, so when the compressor develops problems, the whole unit can begin to struggle.
Common Causes of AC Compressor Damage
Broken air compressors typically need replacement, which can cost nearly as much as replacing the entire unit. Understanding what causes compressor failure in the first place can help you take proactive steps, so you’re never caught off guard by a costly repair bill.
Below are a few causes that can wear out the compressor and lead to its failure.
Lack of maintenance and dirty coils
One of the biggest pitfalls many homeowners make is skipping maintenance services for their air conditioner in Colorado Springs. Each maintenance service includes a thorough inspection, cleaning, and diagnosis of potential problems to prevent unexpected breakdowns and keep your system working as smoothly as possible.
During the appointment, a certified technician performs key steps, such as checking refrigerant levels, testing electrical connections, and cleaning the condenser coils. Without routine tune-ups, dirt and debris can build up on the coils, forcing your compressor to work harder than necessary and eventually overheat.
Refrigerant leaks and pressure issues
One of the most common issues that ruins the compressor is leaking refrigerant lines. When your system starts losing refrigerant because of a leak, the pressure inside your AC drops, forcing the compressor to work harder to compensate for the efficiency loss. The excess strain causes it to wear out faster and eventually fail.
Common indicators of refrigerant leaks include hissing sounds, poor cooling performance, and puddles of liquid around the unit. If you notice any of these signs, contact an air conditioning tech as soon as possible.
Electrical failures and short circuits
Any electrical problem within the AC can cause the compressor to struggle to operate efficiently. The electrical issues that are most damaging to the compressor include:
- Voltage fluctuations caused by power surges or inconsistent power supply.
- Electrical short circuits are caused by damaged wiring, loose connections, overloaded circuits, or faulty components.
- Capacitor problems as a result of defective or failing capacitors that must be replaced.
- Wiring issues from poor design or faulty installation are causing an inadequate power supply to the compressor.
- Motor overload draws an excessive current, causing the compressor to overheat.
Blocked or dirty condenser coils
Contaminants in the system can also take a toll on the compressor. When the condenser coils get clogged, they can slow the work of heat exchange within the system. Your AC has to work harder to cool your home, which can cause excess wear and lead to early compressor failure. Scheduling regular maintenance services in Colorado Springs helps avoid this.
Low or high refrigerant levels
Your AC compressor needs the right balance of refrigerant to do its job. If levels drop too low from a leak, the compressor has to work overtime to circulate refrigerant, which can lead to overheating. On the other hand, overcharging can create excess pressure, putting unnecessary strain on the compressor and forcing it to shut down.
Improper AC installation or sizing
If your AC unit is installed incorrectly or isn’t the right size for your home, the compressor can end up working harder than it should. An oversized system cycles on and off repeatedly, while an undersized unit goes into overdrive to keep up with your cooling needs.
Age and normal wear of AC compressors
With Colorado Springs’ scorching summer temperatures, it’s common for homeowners to leave their AC running all season long. While this keeps your home cool and refreshing, the compressor’s internal parts become worn or damaged over time, eventually leading to failure.
Most compressors are designed to last about 15 to 20 years, so if your AC is in this age range, it may be a good idea to have it checked in preparation for a possible replacement.
Signs Your AC Compressor Is Failing
When your AC compressor stops working correctly, you’ll often notice a few warning signs that something’s not quite right. The most common red flags to watch out for include:
- Weak or limited airflow coming from your vents.
- Strange grinding, clunking, or screeching sounds.
- Your AC is shaking when it turns on.
- Puddles of liquid around the base of your air conditioner.
How To Prevent Compressor Damage
Regular AC maintenance is the best way to avoid paying for the cost of a new AC compressor. Scheduling annual tune-ups helps catch compressor problems early, so you can repair them before they put too much strain on your compressor.
You can also take a few simple steps at home to keep your compressor in top condition, including:
- Keeping the area around the unit clear.
- Changing the air filters every one to three months.
- Keeping vents and registers open.
- Checking refrigerant levels to catch leaks early.
When To Repair vs. Replace an AC Compressor
If a failing compressor is leaving your home sticky and uncomfortable, you may have to decide between AC repair and replacement. The best choice depends on your unit’s age, condition, and budget.
Repairs are most effective when the compressor is under 10 years old and the issue is minor, such as a small electrical fault or a faulty capacitor. A complete AC replacement is a better long-term solution when the unit is nearing the end of its lifespan and has major mechanical damage.
