Is Your Commercial Building Winter Ready?
Micron Mechanical • November 1, 2024
Although winter is fast approaching, there is still time to ensure that you have completed all winterization for your commercial building. Maintaining your building HVAC system is crucial for keeping the building warm, improving air quality, and reducing energy costs. Additionally, poor ventilation can potentially lead to issues like condensation and mold.
Winterizing is an essential component of property management that can also incorporate maintenance and upgrades to help to save on future energy costs. These proactive steps can help avoid costly repairs, increase energy efficiency, and provide a safer, more comfortable environment during the colder months.
HVAC, Ventilation and Indoor Air Quality
- Inspect and Change Filters: Clean or replace filters in furnaces and air handlers. Dirty filters reduce airflow, making the system work harder which increases energy consumption.
- Thermostat Upgrade: Consider installing a programmable or smart thermostat. By adjusting temperatures based on occupancy, you can reduce energy usage and save energy usage during off-hours.
- Ventilation System Maintenance: Clean all ventilation ducts and ensure that fans are working properly to prevent stale air and moisture build-up.
- Humidity Control: Install or check dehumidifiers and humidity sensors if the building is prone to high humidity, which can lead to condensation on windows and walls. Humidity levels should be between 30 – 40% during the winter.
- Schedule a seasonal maintenance assessment with a licensed HVAC technician, to ensure your system is operating safely and up to required specifications. This includes the furnace, heat pump, and boiler, a professional can help identify any problems before they lead to costly breakdowns.
Inspect and Seal the Building Envelope and Ensure Proper Insulation
- Windows and Doors: Check for gaps, cracks, and damaged seals around windows and doors. Use weatherstripping to seal drafts and prevent heat loss. If feasible, consider installing double or triple-pane windows for enhanced insulation.
- Exterior Walls: Examine walls for cracks or signs of wear. Applying caulking or sealant can prevent air leaks, moisture penetration, and pests from entering the building. An exterior waterproofing treatment may also help if the building experiences high rainfall or snowfall.
- Attic and Roof Inspection: Ensure attics and roof spaces are adequately insulated. The insulation material should be evenly distributed, without gaps.
- Ductwork: Ducts that run through cold spaces should be insulated to ensure they keep heated air from cooling as it moves through the building.
Protect Water Systems
- Water Heaters: Check water heaters for leaks or rust. Flushing sediment build-up from the tank can improve efficiency, making it easier to maintain hot water temperatures during the colder months.
- Insulate Pipes: As mentioned with ducts, insulate any exposed or poorly insulated pipes, especially those in unheated areas.
- Outdoor Faucets: Shut off outdoor faucets and drain any remaining water to prevent freezing. Installing frost-free hose bibs is also an option as a long-term solution to help prevent freezing.
Start Thinking About Summer Now
Summer brings soaring temperatures, high humidity, and increased energy demands. Preparing a commercial building for the summer weather during the winter months can ensure that you are able to stay ahead of maintenance issues that could come up with the first spike in temperatures.
Optimize the HVAC System for Cooling, Ventilation, and Airflow
- Professional Inspection: Schedule an HVAC tune-up long before summer begins, typically February-April are good months to start this process. Tune-ups by licensed professionals should include, at the bare minimum: system inspection, coils, refrigerant, and proactive recommendations.
- Change Air Filters: Replace or clean air filters at the start of the season and continue to check them regularly. Clean filters help to improve airflow and reduce strain on the system, resulting in better energy efficiency.
- Use Natural Ventilation: If local conditions permit, take advantage of natural ventilation by opening windows and doors to keep the building cooler. Many types of HVAC equipment operate with an economizer. If the outdoor ambient is cold enough and cooling is required for your facility, it will automatically allow outdoor air to cool and ventilate the space and keep the facility comfortable without using mechanical cooling. This saves money, but it only saves money if it’s functioning properly.
No Matter the Season: Consider an Energy Audit
An energy audit can help identify areas where the building may be losing heat or cooling or is simply using more energy than necessary. You can start by reviewing and comparing utility bills from past seasons to identify spikes or trends in energy usage. This information can help prioritize improvements and help you make better decisions for future upgrades or efficiency improvements.You could also consider seeking out a professional energy audit. A thorough, professional review of utility bills can reveal usage patterns that may lead to improvements. Thermal imaging can help identify heat leaks, cold spots, or areas or energy loss around the building. A professional can help to pinpoint where additional insulation or repairs are needed to ensure you are prepared for the next big change in temperature.
How to Choose a Qualified Residential HVAC Contractor in Vancouver, BC Investing in a new heating and cooling system is one of the most important decisions a homeowner can make. With rising energy costs and increasing interest in heat pumps, many Vancouver, BC homeowners are upgrading their HVAC systems. However, not all installations deliver the same results. Recent discussions around heat pump rebate disputes and contractor certification issues in British Columbia highlight an important point: choosing the right HVAC contractor matters just as much as choosing the right system. Why Choosing the Right HVAC Contractor Matters An HVAC system is a long-term investment that directly impacts your home’s comfort, energy efficiency, and resale value. Poor installation or improper system sizing can lead to higher energy bills, frequent repairs, reduced system lifespan, and inconsistent heating and cooling. Even the best equipment will not perform properly if it is not installed correctly. Look for Red Seal Certification in HVAC/R One of the most important qualifications to look for is Red Seal certification in HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration). This is the highest industry standard in Canada, is recognized globally, and ensures that the technician working in your home has completed the industry’s rigorous 4–6 year apprenticeship training and meets nationally recognized standards. Choosing a Red Seal certified contractor helps ensure your system is installed correctly the first time and reduces the risk of future issues. Understand the Contractor Certification Landscape in BC With the growing demand for heat pumps, British Columbia has seen an increase in rebate-related contractor disputes. Many homeowners assume all HVAC companies qualify for rebate programs, but that is not always the case. Not all contractors are registered with rebate programs, and requirements can vary. Working with an unqualified contractor may impact eligibility or system performance. This makes it essential to focus on overall contractor expertise, certifications, and reputation—rather than rebates alone. Evaluate Maintenance and Service Capabilities Installation is only the beginning. A qualified HVAC contractor should also offer ongoing maintenance and repair services. Homeowners should consider: Whether the contractor offers a maintenance program How they handle repairs and service calls Whether they have experience servicing the systems they install It’s also important to consider the relationship between the contractor and the equipment manufacturer. Strong relationships between manufacturers and contractors can lead to a better overall experience, improved system performance, and in some cases, long-term cost savings on your equipment. A properly maintained system can last 12 to 15 years or longer, while neglected systems often fail much sooner. Choose Industry-Leading Equipment Not all HVAC systems are created equal. A reliable contractor should offer trusted, high-performance brands such as Daikin and Mitsubishi Electric, which are known for efficiency, reliability, and advanced technology. Think of your HVAC system like purchasing a vehicle. A lower-cost option may save money upfront but can lead to higher maintenance costs and a shorter lifespan. A higher-quality system may require a larger initial investment but often delivers better performance and long-term value. Look for a Reputation Built on Craftsmanship Beyond certifications and products, a contractor’s reputation matters. Look for companies that prioritize precision, attention to detail, and customer satisfaction. Reviews and testimonials can provide helpful insight into the quality of work and service you can expect. When evaluating reviews, consider: Do customers mention workmanship and technical expertise? Are reviews focused only on customer service, or do they reflect overall system performance and satisfaction? Is there consistent positive feedback across multiple projects?
