Is your home ready for fall? 🍂🏠

Calgary weather can change quickly, and the first chilly morning has a way of reminding us that fall is officially on its way!

A little preparation now can make a big difference later. Change your furnace filter, check your thermostat, make sure vents are clear, and most importantly, have your heating system inspected before you really need it.

Think of it as your home’s fall check-up. 🍁 A properly maintained HVAC system can help improve efficiency, reduce the risk of unexpected breakdowns, and keep your family comfortable when the temperature starts dropping.

Swipe through our Fall Home Comfort Checklist, then give Sub Zero Technical a call if furnace maintenance is still on your to-do list. We’ll help you get winter-ready before winter decides to show up early. 😉

Your thermostat has a new job. 🌡️

As summer winds down and cooler mornings begin to roll in, your thermostat becomes the key to keeping your home comfortable without wasting energy.

The first chilly morning always seems to arrive sooner than expected. The best time to make sure your furnace is ready isn’t when you need it—it’s before you do.

How do heat pumps actually work? 🤔❄️☀️

One of the biggest misconceptions about heat pumps is that they create heat. They don’t—they move heat.

☀️ In the summer, a heat pump works just like an air conditioner. It removes heat from inside your home and transfers it outdoors, leaving your space cool and comfortable.

❄️ In the winter, it simply reverses the process. It captures heat from the outdoor air—even in cold temperatures—and moves it inside to warm your home.

Because heat pumps transfer heat instead of generating it, they can be an incredibly energy-efficient way to keep your home comfortable year-round.

Curious if a heat pump makes sense for your home in Alberta? We can compare it with a traditional furnace and A/C system, explain the pros and cons, and help you find the solution that fits your home, comfort needs, and budget.

Forest fire smoke outside? Your HVAC filter is suddenly very important. 😅🌫️

When smoke is in the air, your first move should be to reduce how much outdoor air gets inside. Keep windows closed, limit door openings, and make sure your HVAC filter is clean and properly installed.

Your system can only perform well if airflow isn’t restricted, so don’t ignore dirty filters, blocked returns, or overdue maintenance. Better airflow and proper filtration can make a noticeable difference in how your home or building feels during smoky conditions.

Have questions about filters, airflow, or indoor air quality? Ask us.

Commercial HVAC: keeping businesses comfortable ✅❄️☀️

Comfort matters in every business. It affects staff, customers, tenants, equipment, and day-to-day operations. When your HVAC system is running properly, people notice the comfort. When it isn’t, they notice that even faster. 😄

From rooftop units to custom commercial setups, our team has the knowledge and experience to keep your building running the way it should.

Wildfire smoke outside? Keep indoor air quality top of mind. 🌫️🏠

When the air outside is smoky, your HVAC system can play an important role in helping your indoor air feel cleaner and more comfortable.

Start by keeping windows and doors closed, checking your furnace filter, and running your system fan if recommended for your setup.

A clean, properly fitted filter can help reduce airborne particles moving through your home. And if your system hasn’t been serviced in a while, now is a good time to make sure airflow, filtration, and ventilation are working the way they should.

Need help improving your indoor air quality? Give us a call.
