Few things feel worse in the summer than an AC breaking down on a hot day. But like any appliance, your air conditioner can fail if it isn’t cared for properly.
At Airmaxx Heating & Air Conditioning, we’ve seen it all, from simple clogged filters to full system failures. The good news? Most breakdowns can be prevented or solved with the right AC service and repair. Let’s talk about the common reasons your AC breaks down.
1. Dirty or Clogged Air Filters
The most common reason for an AC broken call is a dirty filter. When filters are clogged, airflow is restricted, forcing the system to work harder than it should. This can cause overheating, frozen coils, and higher energy bills. Replacing or cleaning your filter every 1–3 months is a quick fix that prevents big problems.
2. Refrigerant Leaks
Low refrigerant levels mean your AC can’t cool effectively. Leaks reduce comfort and damage the compressor if ignored. Professional technicians can locate the leak, repair it, and refill refrigerant to manufacturer standards.
3. Electrical Failures
Air conditioners rely on complex wiring and fuses. Faulty connections, worn-out capacitors, or tripped breakers can all lead to system shutdowns. These issues require professional AC service and repair, since electrical fixes should never be a DIY project.
4. Frozen Evaporator Coils
If your AC is blowing warm air or not cooling at all, frozen coils may be the culprit. This can result from low refrigerant, poor airflow, or mechanical issues. Proper servicing resolves the cause and prevents long-term damage.
5. Age and Wear
Most AC units last 12–15 years. If yours is older, breakdowns may be more frequent. At some point, repairs may no longer be cost-effective, and a replacement system becomes the better option.
What to Do When Your AC Stops Working
Step 1: Check the Basics
Before calling for help, check your thermostat, power supply, and filter. Sometimes the solution is as simple as replacing batteries or resetting a breaker.
Step 2: Call a Professional
If those quick fixes don’t work, it’s time for expert AC service and repair. A qualified technician can diagnose the issue safely and restore your cooling.
Step 3: Consider Preventive Maintenance
Even after a repair, scheduling annual tune-ups is key to avoiding the same problem again. Preventive maintenance keeps your system running smoothly and extends its lifespan.
How Professional AC Service Helps
A trusted HVAC contractor, like us at Airmaxx Heating & Air Conditioning, offers a complete service rather than just quick fixes. With routine servicing, you can expect:
- Thorough inspections to catch small problems before they become major repairs.
- Cleaning and tune-ups that improve efficiency and lower energy bills.
- Expert repairs that address the root cause, not just the symptoms.
- Reliable guidance on whether repair or replacement is the right choice.
By keeping up with maintenance and timely repairs, you’ll enjoy fewer breakdowns and a cooler, more comfortable home.
Repair or Replace? Knowing the Right Time
If your system is relatively new and still under warranty, repairs often make sense. But if your AC is older, breaking down frequently, or driving up energy bills, replacement may be more cost-effective.
