Calgary summers can be unpredictable, ranging from mild to uncomfortably hot. A functioning air conditioning system is essential for comfort during these warmer months. Recognizing the signs that your air conditioner needs repair helps you avoid sudden breakdowns and keeps your home cool. Here are the top signs your AC may need professional attention, with advice from Icon Plumbing & Heating.
1. Weak or Inconsistent Airflow
Weak airflow is one of the most common signs your air conditioning system needs repair. If your AC is running, but the air coming from the vents is weak or inconsistent, there could be an issue with the system’s blower or ductwork.
Common causes:
- Clogged or dirty air filters that block airflow.
- Faulty blower motor that reduces the system’s ability to push air.
- Blocked or leaking ductwork that disrupts even distribution.
How to address it:
- Replace or clean air filters monthly.
- Schedule a professional inspection to check for motor issues or duct obstructions.
- Maintain your system with regular HVAC maintenance from a trusted Calgary air conditioning service like Icon Plumbing & Heating.
2. Strange Noises Coming from the Unit
Air conditioners should operate quietly. Loud, unusual noises indicate mechanical issues that need attention. Different types of noises point to different problems.
Types of noises and their meanings:
- Grinding or squealing: May indicate worn-out motor bearings.
- Banging or clanking: Could mean a loose or broken component inside the unit.
- Hissing: Suggests a potential refrigerant leak.
Why you shouldn’t ignore these sounds:
- Noises mean parts are likely wearing out, which leads to more extensive damage.
- Ignoring these signs results in higher repair costs or complete system failure.
Scheduling an immediate inspection when you hear strange noises prevents further damage and keeps repair costs manageable.
3. Warm Air Blowing from Vents
Your AC should consistently provide cool air. If it starts blowing warm air, there is an issue that needs to be addressed.
Possible causes of warm air:
- Low refrigerant levels due to leaks.
- Compressor issues that prevent the cooling cycle from starting.
- Faulty thermostat that inaccurately reads room temperature.
Steps to take:
- Check the thermostat to make sure it is set to “cool” mode.
- Ensure there are no power issues with the system.
- Contact an HVAC professional in Calgary for a detailed inspection and refrigerant recharge, if needed.
Warm air indicates that your air conditioning system is not cooling efficiently and will struggle to maintain the desired temperature.
4. Unpleasant Odours Coming from the Unit
A properly functioning air conditioning system should not produce any strong or unusual odors. If you smell something off, it points to an underlying issue.
Common odors and their causes:
- Musty smell: Indicates mold or mildew growth within the unit or ductwork.
- Burning smell: Suggests electrical issues or overheating parts.
- Chemical smell: May indicate a refrigerant leak.
What to do:
- Replace filters and clean ducts if the odor is mild and related to dust.
- Have an HVAC technician inspect the unit for mold or electrical problems.
- For refrigerant leaks, get professional service immediately from a reputable Calgary HVAC company like Icon Plumbing & Heating.
Addressing odors promptly prevents health issues and ensures your air conditioning system works efficiently.
5. High Energy Bills Without Increased Usage
A sudden spike in your energy bills without an increase in usage suggests your AC is not working as efficiently as it should. This could be due to worn-out parts or underlying issues that force the system to work harder.
Possible reasons for high energy bills:
- Leaking or dirty ducts that reduce system efficiency.
- Aged or failing compressor that uses more power.
- Dirty coils that reduce the system’s cooling ability.
How to reduce energy consumption:
- Schedule regular maintenance to keep the system clean and efficient.
- Check and seal ductwork to prevent energy loss.
- Upgrade older parts with energy-efficient alternatives recommended by an HVAC specialist in Calgary.
Maintaining an energy-efficient AC saves you money and ensures the system can handle Calgary’s hot weather when needed.
