Common AC Problems: When to Repair vs. Replace
Knowing when to repair your air conditioner or invest in a replacement can help you avoid unnecessary expenses and inconvenience. Below are the most common signs you need expert air conditioning service & repair—or a full system upgrade.
Signs You Need a New AC System
Inconsistent Cooling & Poor Airflow
Rooms that cool unevenly, weak air circulation, or a system that can’t keep up during extreme heat are signs your air conditioner might be outdated or incorrectly sized. An improper setup can prevent your AC from cooling efficiently, no matter how new it is.
High Energy Bills
Aging air conditioning systems typically become less efficient over time. If you’re seeing higher electricity bills even though your usage hasn’t changed, your AC might be overworking to deliver the same cooling output.
Strange Noises or Odours
Unusual sounds—like grinding or rattling—can point to loose or damaged parts. Foul or musty smells may signal mould inside the unit or ductwork, which can reduce indoor air quality and indicate it’s time for a replacement.
Fixable AC Issues with Air Conditioning Service & Repair
Thermostat Malfunctions
When your thermostat doesn’t respond, turns off unexpectedly, or reads temperatures incorrectly, it can affect your home’s comfort. Calibrating or replacing it can often solve the problem easily.
Refrigerant Leaks
Warm air coming from your vents may mean low refrigerant levels. Our team can safely detect and seal the leak, then recharge the system so it cools like it should.
Electrical or Sensor Issues
Defective components like sensors or capacitors, along with loose wiring, can cause your AC to stop working or operate inconsistently. Most of these issues are fixable with a professional repair, helping you avoid a complete replacement.
If you’re not sure whether to repair or replace your AC, our team at Dunn Heating and Air Conditioning can evaluate your system and offer the best recommendation for your Waterloo home.

What Maintenance Does a New AC System Require?
Schedule yearly maintenance to inspect refrigerant levels, clean key components, and check system performance. Replace your air filters every 1–3 months for cleaner airflow and better efficiency. Keep the outdoor unit clear of debris like leaves and branches to avoid blockages. Preventive air conditioning services reduce the risk of breakdowns and extend your AC’s life.
How Much Does Air Conditioning Repair Cost?
Repair costs vary depending on the issue. Simple problems like a broken thermostat or blocked drain can be inexpensive to fix, while major repairs like compressor failure or refrigerant leaks may cost more. If your AC is more than a decade old or needs repairs frequently, it might make more sense to replace it. Dunn Heating and Air Conditioning will inspect your system and help you choose the best option for your budget and comfort needs.
