Our Air Conditioning Repair Process

Step 1: Full System Inspection

We start by examining your entire air conditioning system, including the condenser, evaporator coils, compressor, wiring, and refrigerant levels, to pinpoint the exact issue. This prevents unnecessary repairs and helps catch potential problems early, making your air conditioner repair more effective.

Step 2: Advanced Diagnostic Testing

Using specialized tools, we test for thermostat malfunctions, refrigerant leaks, motor failures, and electrical problems, ensuring we fix the root cause—not just the symptoms. This thorough testing process helps us provide the most accurate air conditioning service possible.

Step 3: Upfront Repair Recommendations

Our technicians explain the issue in simple terms, outline your repair options, and provide clear, upfront pricing so there are no surprises when it comes to costs.

Step 4: Reliable Parts Replacement

If a component needs replacing, we use high-quality parts like capacitors, fan motors, and thermostats. Because our service vehicles are fully stocked, we can complete most air conditioning repairs on the spot, saving you time and restoring your home’s comfort faster.

Step 5: System Cleaning & Efficiency Boost

A properly maintained system runs more efficiently. That’s why we clean key components such as condenser coils, air filters, and drain lines to improve airflow, cooling efficiency, and energy savings. This step in our air conditioning service helps prevent future breakdowns and lowers energy costs.

Step 6: Final Testing & Optimization

Before we leave, we test temperature output, airflow, and overall system performance. We also make final adjustments as needed, so your home stays cool and comfortable after your air conditioning repair.

Common Air Conditioning Problems

Even a well-maintained air conditioner can develop issues over time. Here are some of the most common AC problems that require professional air conditioning repair:

AC Running but Not Cooling

  • Refrigerant Leak: Low refrigerant levels can prevent your AC from absorbing heat efficiently.
  • Thermostat Malfunction: A faulty thermostat may not signal the AC to start or maintain the right temperature.
  • Blocked Condenser Coils: Dirt and debris buildup on the condenser coils can reduce heat dissipation.

AC Won’t Turn On

  • Faulty Capacitor: A worn-out capacitor can prevent your system from starting, often causing clicking noises.
  • Electrical Failure: Wiring issues, a damaged relay, or a power supply failure can prevent the AC from turning on.
  • Tripped Breaker or Blown Fuse: A power surge, short circuit, or overloaded system can trip the breaker or blow a fuse, cutting power to the AC.

Strange Noises or Leaks

  • Buzzing or Rattling Sounds: Loose parts or failing electrical components may cause unusual noises.
  • Hissing Sound: This may indicate a refrigerant leak or high-pressure gas escaping from a faulty valve.
  • Water Pooling Around the Unit: A clogged condensate drain can cause water buildup, leading to leaks, mould growth, or system shutdown.
If you’re dealing with any of these problems, AtlasCare’s certified technicians are ready to help. We’ll quickly diagnose the issue, provide clear repair solutions with upfront pricing, and get your AC running efficiently again.

How Often Should I Have My Air Conditioner Serviced?

Your AC should be serviced once a year, ideally in the spring, before the summer heat arrives. Regular air conditioning service helps prevent breakdowns and extend your unit’s lifespan. A professional technician will clean the coils, check refrigerant levels, and test electrical components. Scheduling annual air conditioning repair and maintenance can also help catch small issues early.

How Much Does It Cost to Fix an Air Conditioner That is Not Cooling?

The cost of air conditioner repair depends on the issue. Common problems include refrigerant leaks, clogged condenser coils, or a faulty thermostat, all of which require professional diagnosis and repair. Some fixes are simple, while others may involve more extensive air conditioning repair services.

How Many Years Does an Air Conditioner Last?

Most central air conditioning systems last 10 to 15 years, while window units typically have a shorter lifespan of 8 to 10 years. However, with regular maintenance and timely repairs, some systems can operate efficiently for 20 years or more.

When Should I Replace my AC?

If your AC is over 10–15 years old, frequently breaks down, or no longer cools efficiently, it may be time to consider replacing it instead of ongoing air conditioner repair. If repair costs add up to nearly half the price of a new system, upgrading to a high-efficiency unit can save you money on future air conditioning service and energy bills. AtlasCare’s experts can assess your current system, compare repair vs. replacement costs, and help you choose the best solution for your home and budget.
