How Ice Can Affect Heating and Cooling Systems in Edmonton, Alberta: A Guide by Gateway Builders

As a business owner, ensuring that your HVAC (heating, ventilation, and air conditioning) systems are functioning efficiently during the cold season is crucial for maintaining a comfortable and safe environment for employees and customers.

At Gateway Builders, we specialize in commercial snow removal, but we also understand how ice buildup can lead to serious issues with your heating and cooling systems. In this blog post, we’ll explore how ice affects these systems, the common problems that arise, and how regular snow and ice removal can help protect your HVAC units.

1. Blocked Airflow and Reduced Efficiency

One of the most common ways ice affects heating and cooling systems is by obstructing airflow. Ice can accumulate on exterior HVAC units, such as heat pumps and air conditioners, leading to blockages that reduce their ability to circulate air effectively.

  • Outdoor Units Covered in Ice: In Edmonton’s harsh winters, outdoor units can become covered in snow and ice, preventing the proper exchange of heat. This can force the system to work harder, reducing its efficiency and increasing energy costs. Additionally, a lack of airflow can cause the system to overheat or shut down completely.
  • Ice Blocking Vents: Snow and ice buildup around vents can also block airflow, preventing warm air from circulating inside the building. This can leave employees and customers uncomfortable and put extra strain on the system, which may eventually lead to malfunctions or breakdowns.

2. Frozen Coils and Damage to HVAC Components

Ice formation on the evaporator or condenser coils of your HVAC system can lead to serious damage. Coils are responsible for the heat exchange process, and when they become encased in ice, they cannot function properly.

  • Evaporator Coil Freezing: In heating systems, evaporator coils are crucial for absorbing heat. When these coils freeze over, the system can no longer heat the air effectively, leading to colder indoor temperatures. A frozen coil can also cause the entire system to stop working, requiring costly repairs or even replacement of the affected components.
  • Condenser Coil Freezing: Condenser coils are responsible for releasing heat outdoors. In cold weather, snow and ice can build up on these coils, reducing their ability to function. This can lead to overheating and damage to the compressor, one of the most expensive parts of an HVAC system to repair or replace.

3. Compressor Overload and System Shutdowns

When ice builds up on HVAC systems, particularly heat pumps, it can lead to compressor overload. The compressor works to move refrigerant through the system, but if it is forced to operate under icy conditions, it can become overloaded and overheat.

  • Compressor Damage: Ice buildup restricts the compressor’s ability to regulate refrigerant flow, causing it to work harder and increasing the likelihood of damage. Compressors are expensive to repair or replace, and a damaged compressor can result in extended system downtime during critical winter months.
  • System Shutdowns: If ice is not removed from the system in a timely manner, the HVAC unit may shut down entirely to prevent further damage. This leaves your business without heating or cooling, which can be especially problematic in extreme winter conditions in Edmonton.

4. Increased Energy Costs

When HVAC systems are covered in ice or snow, they have to work harder to maintain desired temperatures. This increased effort leads to higher energy consumption, which results in rising utility bills during the winter months.

  • Poor System Efficiency: Ice buildup limits the efficiency of HVAC units, forcing them to run for longer periods to achieve the same level of heating or cooling. Over time, this increased energy usage can lead to significant financial strain for businesses already dealing with higher winter-related costs.
  • Higher Maintenance Costs: Along with increased energy usage, HVAC systems exposed to ice buildup may require more frequent maintenance and repairs. This can quickly add up, making winter an expensive season for businesses with poorly maintained heating and cooling systems.

5. Structural Damage to HVAC Systems

Edmonton’s harsh winter conditions can lead to long-term damage to the structural components of HVAC systems. Prolonged exposure to ice and freezing temperatures can weaken exterior components, such as the fan blades, housing, and mounting brackets.

  • Corrosion and Rust: Ice can cause moisture to build up on the metal parts of HVAC units, leading to rust and corrosion. Over time, this deterioration can compromise the structural integrity of the system, resulting in more frequent repairs or the need for a full replacement.
  • Cracked or Broken Components: As ice expands and contracts, it can put pressure on the system’s components, causing cracks or breaks in the housing or mechanical parts. These damages are often not immediately noticeable but can lead to more severe issues if left unchecked.

How Gateway Builders Can Help Protect Your HVAC Systems

At Gateway Builders, we specialize in commercial snow removal, which plays a key role in protecting your business’s HVAC systems during the winter. Here’s how our services can help:

  • Regular Snow and Ice Removal: We provide timely snow and ice removal services that prevent ice buildup around HVAC units, vents, and exterior components. By clearing snow from your property, we help ensure that your heating and cooling systems remain unobstructed and efficient.
  • Roof Snow Clearing: Heavy snow on rooftops can create ice dams that affect your building’s ventilation and HVAC systems. Our roof snow clearing services prevent ice from forming on or around key components, reducing the risk of damage.
  • Customized Snow Removal Plans: Every business is unique, and we offer tailored snow removal plans to fit your specific needs. Whether you need regular snow clearing or emergency services during heavy snowfall, Gateway Builders has you covered.

Conclusion

In Edmonton, ice and snow can have a major impact on your business’s heating and cooling systems. From blocked airflow and frozen coils to increased energy costs and system damage, winter conditions can cause a variety of problems for HVAC units. However, with proactive snow removal services from Gateway Builders, you can protect your systems, reduce the risk of costly repairs, and keep your business comfortable all winter long.
