  • Customizable preventative maintenance programs suited to your needs and budget.

Your AC experts.

We’ve served industrial, institutional, and commercial heating, ventilation, and air conditioning (HVAC) customers across western Canada since 1968. Despite over 50 years of expertise in commercial and industrial HVAC applications, we continue to innovate and lead our industry.

For starters, by using better components and controls, our systems operate more efficiently. That means energy savings, longer component lifecycles, and more comfortable, consistent temperatures.

Need equipment specialized to handle your climate?

That’s what we do. North of the 48th parallel, we do what our competitors can’t. Our team lives where we service—so we understand what that means for equipment.

Whether it’s -55°C (-67°F) in Fort McMurray, 41°C (105.8°F) in Kelowna—or just the typical 80°C annual weather swings of the Canadian prairies, we live here.

That’s how we’re able to design-build, design-assist, and service equipment to fit your needs and climate. Seasonal maintenance is one of our core offerings, because we know this helps ensure your equipment’s longevity and your overall business success. We help you ensure your equipment is optimized for season-specific use and winterized properly for year-round use.

Air Conditioning FAQs


Turns out it’s not just about pleasing fussy people.

The people at Harvard have been studying how to make healthier buildings for over 40 years. They list temperature as one of the nine foundations of a healthy building. Temperature often compounds other indoor environmental problems—for example, high temperatures increase building material off-gassing, releasing irritating and toxic chemicals, like volatile organic compounds (VOCs) into the air.

Many people only consider temperature in terms of comfort, but it also directly affects productivity. If your temperature is outside the optimal range of 20–26°C (68–79°F), for every 0.5°C (1°F) away from comfort, productivity decreases by 2%. So, for every degree away from comfort, if you take the average Canadian hourly wage, then a 2% drop in productivity can cost a business $4,200/year/person.

Short answer? It all depends on your needs!

For example, our customers’ spaces range from commercial offices to hot yoga studios—all the way to customers whose entire food production area is a massive walk-in cooler!

That said, the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE), Standard 55-2013 suggests maintaining an indoor temperature of 20 – 26°C (68–79°F). Preferences vary, but this range tends to be most comfortable, with 23°C (74°F) as a happy medium for most. Every space in your building should ideally be comfortable and properly balanced so you don’t find spots where it’s too cold, drafty, or too hot.

We also recommend setting seasonally-specific temperatures. Adjusting to seasonal climates reduces utility costs and is often more comfortable than jarring indoor/outdoor temperature swings.

In the winter, aim for 20–24°C (68–75°F) and in the summer, aim for 24–27°C (75–81°F).

We sure can!

Improving indoor air quality can improve occupant health and experience—in addition to performance and productivity. Better air quality can even lower absenteeism and turnover, while boosting your bottom line.

As a full-service HVAC (heating, ventilation, and air conditioning) company, our indoor air quality experts can help you enhance your occupants’ safety and experience in your building, facility, or space.

Our indoor air quality offerings include:

Navigating refrigerant options can be daunting. Our goal is to keep it simple for you. For decades we’ve created systems that are cost-effective, energy-efficient, durable, and easily serviceable.

We’re proficient with all refrigerants from CO2 to R404A. We can even help with R22 (freon) retrofits if you’re ready to convert your equipment to a more sustainable and economically viable option.

Most importantly, we’ll work with you to understand your needs and recommend options that work for you.

By using better components, our systems operate more efficiently—which pays off in energy savings, component lifecycle, and carbon footprint. Retrofitting or modifying existing systems can reduce your energy bills. There may even be rebates available in your area for businesses reducing their energy emissions.

Did you know air conditioning alone accounts for roughly 8.5% of worldwide electricity use? Canada has higher and lower temperature extremes than most countries, so our buildings have to compensate for those extremes. That’s just one reason why energy accounts for 82% of Canada’s total emissions.

We all love saving money, and that’s even more satisfying when investments contribute to a sustainable future.

Here’s some quick tips:

  1. Make sure your thermostats are in the right locations
  2. If possible, keep unnecessary lights off and blinds and windows closed, when your air conditioning is running
  3. Manage your humidity
  4. Only use air conditioning when necessary
  5. Maintain your air conditioning unit

Short version: aim for 40–50% relative humidity—provided that it works in your system and your climate. 

Want to know how we arrived at that number? As far as the upper limit, studies show elevated humidity worsens perceptions of indoor air quality. Relative humidity levels >65% also promote growth for mold, microbes, and pests like dust mites.

According to the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE; Standards 55-2013 and 62-2016), there aren’t established lower humidity limits for thermal comfort.

However, ideal relative humidity levels for indoor comfort tend to fall in a range of 30–50%.

At a minimum, the National Library of Medicine suggests a humidity of at least 40% helps your eyes, skin, airways—and helps you fight bacterial and viral infections. That humidity balance boosts your immunity against biological contaminants—such as bacteria and viruses. Further to that, a recent study even showed the novel coronavirus/COVID-19 deactivates fastest on surfaces at 50% relative humidity.

Not sure if your humidity settings are right for your system and climate? When in doubt, talk to the professionals about your specific case.

It’s already built, so how do I maintain it?

To maintain ideal temperatures consistently throughout your building or space, we recommend regular preventative maintenance. If your space feels too hot, too cold, or inconsistent, maintenance addresses the easiest solutions to rule out. Sometimes it’s merely needing to repair and maintain HVAC equipment that’s causing discomfort, lost productivity, and inconsistent temperatures.

Downtime isn’t an option for successful, efficient businesses. You’ve invested in your equipment, so our preventative maintenance programs aim to help that equipment exceed its projected lifespan. Our team of licensed HVAC technicians service, repair, and maintain all makes and models—regardless of who installed it. When you work with us, you can also track work orders, on demand.

Our commercial and industrial refrigeration technicians help ensure your equipment remains at peak performance. We’ve got you covered.
