HVAC Contractor Calgary | Living in Calgary means facing a unique range of weather conditions, from freezing cold winters to hot summer days. This drastic change in temperatures means that your HVAC (Heating, Ventilation, and Air Conditioning) system is crucial for year-round comfort. But like any system, HVAC units can experience problems, especially when they’re subjected to Calgary’s harsh climate. In this blog, we will discuss common HVAC problems homeowners face in Calgary and some solutions to keep your home comfortable all year long.
1. Uneven Heating or Cooling
One of the most frequent HVAC complaints in Calgary homes is uneven heating or cooling. Certain rooms may feel warmer or cooler than others, which can make it difficult to maintain a consistent temperature throughout your home. This issue can arise from several factors, including:
- Dirty or blocked air ducts
- Incorrectly sized HVAC systems
- Thermostat placement issues
How to Fix It
Start by checking the vents and making sure they are open and not blocked by furniture or debris. Clean the air filters regularly to ensure smooth airflow. If this doesn’t solve the problem, it’s wise to have a professional HVAC contractor Calgary inspect your system. An expert can evaluate if your unit is the right size for your home or whether your ductwork needs repair or adjustment.
2. HVAC System Short Cycling
Short cycling refers to when your HVAC system turns on and off more frequently than normal. This can lead to increased wear and tear on the system, causing it to break down sooner. Short cycling can be caused by:
- A clogged air filter
- A thermostat issue
- Improper refrigerant levels
How to Fix It
Start by replacing your air filter if it’s dirty. A clogged filter can force the HVAC system to work harder, causing it to short cycle. If the problem persists, it might be related to thermostat misplacement or refrigerant leaks. In these cases, contacting a local HVAC contractor in Calgary for inspection and repairs is your best bet.
3. Unpleasant Odors Coming from the HVAC System
Bad odours coming from your HVAC system can be alarming. These smells may be a sign of mould growth, burnt wiring, or even a gas leak. The most common causes of bad HVAC odours include:
- Accumulation of moisture leading to mould in ducts
- A clogged drain pan
- Electrical issues
How to Fix It
A burning smell may indicate an electrical problem, so immediately turn off your system and call a professional if you detect this. If the odour is musty, mould or mildew may be growing in the ducts. A professional cleaning service will be required to clean and disinfect the ducts and vents. Keeping your HVAC system well-maintained will help prevent these issues from arising.
4. High Energy Bills
Sudden spikes in your energy bills during Calgary’s peak summer or winter months may indicate an inefficient HVAC system. A well-functioning HVAC system should keep your home comfortable without skyrocketing your utility costs. Some reasons for high energy bills include:
- Leaky ducts
- Aging HVAC units
- Poor insulation
- Lack of regular maintenance
How to Fix It
Ensuring that your HVAC system is regularly maintained can reduce energy consumption significantly. This includes cleaning the filters, checking for air leaks, and ensuring that the ductwork is properly insulated. If your HVAC system is old, consider upgrading to a more energy-efficient model to save on monthly bills.
5. Frozen Evaporator Coils
In Calgary’s cold winters, frozen evaporator coils can be a common issue. This problem can occur even during the summer if your air conditioner is overworked or the airflow is restricted. Common causes include:
- Low refrigerant levels
- Dirty air filters
- Blocked vents
How to Fix It
If you notice ice building up on your unit, turn it off to prevent further damage and allow the ice to melt. Make sure the air filter is clean, as dirty filters can restrict airflow and cause freezing. If the issue persists, low refrigerant might be the culprit, requiring the attention of a professional HVAC contractor.
6. Noisy HVAC Unit
Unusual noises coming from your HVAC system can be frustrating and signal that something is wrong. Different sounds can point to specific issues, such as:
- Squealing or screeching: A sign of worn-out belts or motor bearings.
- Rattling: Loose components or debris in the system.
- Banging: A more serious issue like a broken part or a misaligned fan.
How to Fix It
Turn off the HVAC system and inspect it for any loose parts or debris. Tighten any loose screws and clean the unit. For more serious sounds like banging or screeching, contact a professional to assess and repair the damage to avoid further issues.
7. Thermostat Malfunctions
Your thermostat is the brain of your HVAC system, and when it malfunctions, your entire system may suffer. Some common thermostat issues include:
- Inaccurate temperature readings
- Failure to turn the system on or off
- Poor placement, like being installed in direct sunlight
How to Fix It
If your thermostat is not working correctly, start by replacing the batteries. If the problem persists, you may need to recalibrate the device. Make sure your thermostat is placed in an optimal location where it can accurately read the room’s temperature. For more complex issues, consider upgrading to a programmable or smart thermostat, which can also help with energy efficiency.
8. Poor Air Quality
Indoor air quality is a growing concern, especially in cities like Calgary where construction and urban development can lead to more dust and pollutants. If you notice that your indoor air feels stuffy or your allergies are acting up more than usual, your HVAC system might not be filtering air properly. Common causes of poor air quality include:
- Clogged air filters
- Dirty ductwork
- Lack of ventilation
How to Fix It
Regularly changing or cleaning air filters can dramatically improve air quality. If your air quality doesn’t improve, professional duct cleaning might be necessary to remove dust, mould, and other allergens. Additionally, installing an air purifier can help to reduce indoor pollutants further, providing cleaner and healthier air.
9. Pilot Light or Ignition Issues
Older furnaces in Calgary homes may experience issues with their pilot light or ignition. If your furnace won’t turn on, or if the pilot light keeps going out, this could signal:
- A faulty thermocouple
- A clogged burner
- An issue with the gas supply
How to Fix It
First, check to see if the pilot light is simply out and needs to be relit. If relighting the pilot doesn’t work, or if the flame is yellow instead of blue, you could have a bigger problem. Gas leaks or blockages require immediate attention from a qualified HVAC professional.
10. Leaky Ductwork
Leaky ducts can cause air to escape before it reaches its intended rooms, leading to uneven heating or cooling and increased energy costs. This is especially problematic in Calgary’s older homes, where ductwork may be outdated or improperly installed.
How to Fix It
Seal any visible cracks or holes in your ductwork with specialized duct tape or mastic sealant. However, for comprehensive duct repairs, it’s best to hire an HVAC contractor who can assess the system and provide a long-term solution. Sealing ducts properly ensures efficient airflow and better performance from your HVAC system.
