Our Air Conditioning Repair Process
Step 1: Full System Inspection
We begin with a full checkup of your AC system, including condenser, compressor, evaporator coils, refrigerant, and wiring. This thorough inspection allows us to find the real issue and spot early warning signs that could turn into bigger problems.
Step 2: Advanced Diagnostic Testing
Our technicians use advanced tools to check for refrigerant leaks, electrical issues, thermostat problems, and fan motor failures. This helps us zero in on the real cause of your system failure and apply the most accurate fix.
Step 3: Upfront Repair Recommendations
You’ll get a clear explanation of the problem, what repairs are needed, and an upfront quote, so there are no surprises when the work is done.
Step 4: Reliable Parts Replacement
We carry top-quality replacement parts on our fully stocked service trucks, from fan motors and capacitors to thermostats and relays. That means we can often complete the repair right away and restore your cooling without delay.
Step 5: System Cleaning & Efficiency Boost
As part of the repair, we also clean components like filters, drain lines, and coils. This not only enhances airflow and performance but also helps reduce energy consumption and prevent further issues.
Step 6: Final Testing & Optimization
Before we wrap up, we verify system airflow, cooling output, and functionality. We make any necessary tweaks to maximize performance so your AC keeps your home cool after the repair is complete.
Common Air Conditioning Problems
Even the most reliable systems experience wear and tear. Below are some of the most frequent issues that may require professional air conditioning repair:
AC Running but Not Cooling
- Refrigerant Leak: If your system is low on refrigerant, it won’t be able to remove heat from your home effectively.
- Thermostat Malfunction: When your thermostat isn’t working correctly, your AC might not maintain the desired temperature or even start properly.
- Blocked Condenser Coils: Accumulated dirt and debris can block heat from escaping, making your system work harder and less effectively.
AC Won’t Turn On
- Failed Capacitor: A damaged capacitor can stop your air conditioner from powering on, often accompanied by a clicking sound.
- Electrical Failure: Wiring problems, power failures, or broken relays can prevent your system from turning on.
- Tripped Breaker or Blown Fuse: Overloaded circuits or short circuits may cut off power to the unit, stopping it from running.
Strange Noises or Leaks
- Buzzing or Rattling: Unusual noises often point to loose parts or worn electrical components that need immediate attention.
- Hissing Sound: A refrigerant leak or escaping high-pressure gas can make a hissing noise and reduce system performance.
- Water Pooling Around the Unit: Blocked drain lines can lead to water backing up and leaking around your system, possibly causing mould or system shutdowns.
If you’re facing any of these problems, Dunn Heating and Air Conditioning’s experienced technicians are available across the Waterloo region. We’ll accurately diagnose the issue, explain the solution clearly, and complete the repair quickly so your AC is back to peak performance in no time.

How Often Should I Have My Air Conditioner Serviced?
To keep your air conditioner in top shape, schedule professional service once a year—preferably during spring. This timing allows for preventative care before summer temperatures rise. Regular air conditioning service includes cleaning, refrigerant checks, and system testing to avoid bigger issues down the line.
How Much Does It Cost to Fix an Air Conditioner That Is Not Cooling?
Repair costs can vary depending on the issue. Some common repairs involve refrigerant recharging, fixing a malfunctioning thermostat, or cleaning blocked coils. Dunn Heating and Air Conditioning’s team in Waterloo can assess the problem and recommend cost-effective air conditioning repair solutions based on your system’s condition.
How Many Years Does an Air Conditioner Last?
Central AC units usually last 10 to 15 years, and portable or window models tend to last around 8 to 10 years. However, regular servicing and timely repairs can significantly increase an air conditioner’s lifespan, sometimes beyond 15 or even 20 years with proper care.
When Should I Replace My AC?
You should start considering a replacement if your air conditioner is more than 10–15 years old, keeps breaking down, or struggles to cool your home efficiently. When frequent repairs start to add up—especially if they approach half the cost of a new unit—it might be more economical to upgrade. Dunn Heating and Air Conditioning can help homeowners in Waterloo evaluate their options and choose the most energy-efficient solution for their budget.
