Our Air Conditioning Repair Process
Step 1: Full System Inspection
Every air conditioning repair starts with a thorough evaluation. We inspect the key components—like the compressor, evaporator, condenser, wiring, and refrigerant levels—to isolate the root issue. By catching the problem early, we help you avoid unnecessary work and keep costs under control.
Step 2: Advanced Diagnostic Testing
Our team uses professional-grade tools to check for thermostat failures, electrical malfunctions, refrigerant issues, and motor defects. This diagnostic approach ensures we identify and resolve the actual cause of failure—not just the symptoms—so your air conditioning service delivers lasting results.
Step 3: Upfront Repair Recommendations
Once the problem is confirmed, we walk you through your options. We explain the issue in plain English, outline your choices, and give you a clear price before any work begins. No jargon, no pressure—just honest guidance so you can make the best decision.
Step 4: Reliable Parts Replacement
If a repair calls for parts, we use only trusted components that meet manufacturer standards. From capacitors to blower motors and thermostats, our fully stocked vehicles carry what we need to complete most air conditioner repairs during the first visit. That means less waiting—and faster results.
Step 5: System Cleaning & Efficiency Boost
Every repair includes a basic system tune-up. We clear debris from condenser coils, rinse clogged drain lines, and change filters if needed. This service not only improves your AC’s efficiency but also helps avoid future service calls. It’s one more way we go beyond a basic fix.
Step 6: Final Testing & Optimization
Before we leave, we run final tests to check cooling performance, airflow, and thermostat calibration. We make any fine adjustments needed and confirm that everything’s working smoothly. Your system is restored to full function—so you’re set for the next heatwave.
Common Air Conditioning Problems
Even with regular use, your air conditioner can run into problems. Here are a few of the most common issues that call for professional air conditioning repair:
AC Running but Not Cooling
- Refrigerant Leak: If the system is low on refrigerant, it can’t remove heat effectively.
- Thermostat Malfunction: Faulty temperature control can prevent your AC from reaching the set point.
- Blocked Condenser Coils: Buildup on the condenser coils blocks heat exchange and reduces efficiency.
AC Won’t Turn On
- Faulty Capacitor: The unit can’t start without this small but critical component.
- Electrical Failure: Loose wiring or burnt relays can interrupt power to the system.
- Tripped Breaker or Blown Fuse: Often caused by a short circuit or system overload.
Strange Noises or Leaks
- Buzzing or Rattling Sounds: Loose panels, broken fan blades, or compressor issues could be to blame.
- Hissing Sound: A sign of refrigerant escaping or valve pressure problems.
- Water Pooling Around the Unit: A blocked drain line can cause pooling water or internal leaks.
If your system is experiencing any of the above, Oosterveld Heating’s certified technicians are ready to help. We’ll diagnose the issue, explain your repair options, and restore your cooling quickly.

How Often Should I Have My Air Conditioner Serviced?
We recommend a full air conditioning service once per year, ideally in the spring before peak usage. Regular maintenance includes cleaning coils, checking refrigerant levels, inspecting the blower, and testing safety features. It helps extend the lifespan of your unit and ensures reliable performance when it’s needed most.
How Much Does It Cost to Fix an Air Conditioner That Is Not Cooling?
It depends on the issue. Minor problems like clogged filters or thermostat calibration are more affordable to fix. Larger repairs—like compressor replacement or refrigerant recharge—can be more involved. Our team provides clear quotes before starting any air conditioner repair so you’re never caught off guard.
How Many Years Does an Air Conditioner Last?
Most central air conditioners last 10–15 years with consistent care. Ductless systems may last longer. With regular maintenance and timely air conditioning repair, many systems continue running efficiently beyond 15 years. If your unit is older, we can help assess its condition and advise on whether repair or replacement is the better choice.
When Should I Replace My AC?
If your system needs frequent repairs, struggles to cool evenly, or is more than 12–15 years old, replacement may be the smarter option. If your repair costs are nearing half the cost of a new unit, a high-efficiency replacement can provide better comfort and energy savings. Oosterveld can help you compare options and make the right call for your home.
