I highly recommend this team. Asif was incredibly helpful, clearly explaining the heat pump installation and the Greener Homes Loan process. Mohammed’s installation was top-notch; his attention to detail with the wiring and system integration was impressive. The entire process was smooth and professional. 5/5 for their great work, and I will definitely use their services again.
We hired Comfort Union in March 2024 to handle a full basement project—HVAC, a cold-climate heat pump, a Rinnai Sensei RX tankless water heater, gas-fitting for the dryer, stove, BBQ and furnaces, plus a Novo water softener and reverse-osmosis system. From the first phone call to the final walkthrough, every member of the team—Asif, Mohammad and the rest—was a pleasure to work with.
Like any big job, we hit a few bumps, but the crew always made things right without hesitation. I really appreciated their forward-thinking approach: they helped us size everything properly so our 100-amp electrical panel and new Carrier furnace with Ecobee thermostat would serve us well for years. They also guided us through secondary-suite building codes and suggested smart upgrades that will save energy (and headaches) down the road.
Since the work was completed, we’ve already referred several friends and neighbours to Comfort Union—and they’ve been just as impressed. Simply put, this is the best HVAC company in Calgary. We’re grateful for their expertise and honesty, and we look forward to working with them whenever the next project comes up. Highly recommended! God bless.
I purchased 2 units of 40gal. Bradford White gas water heater believed for quality product built in U.S. with 6 yrs. Warranty thru Comfort Union . Great customer service planning and paperwork.Tech Mohammad arrived on time for the job and completed the installation and put in service without problem.I look forward for many more years using their product.
Mohammed and his son were pleasant guests in our home and were very generous with their knowledge and expertise while replacing our water tank. I’ll be calling them again next time!
I had excellent service from Mohammad. He was very knowledgeable, he showed and explained to me the work he had done – very professional. His explanations throughout the service were very much appreciated and allowed me to make choices throughout the process. That was so comforting given the difficult situation I was in at that time. We had a terrible experience with another company that was upselling us for so many things not needed. I will absolutely recommend Comfort Union to anyone asking me for a reference.
The service is top notch! They contacted me very quickly and we had the water heater installed the next day. Mohammad is a professional and knows his job well, explained everything in detail and answered all our questions. We are looking forward to using your services again!
I highly recommend Comfort Union! During a recent cold snap, I found myself without a furnace, and I received exceptional service. All of my options were clearly explained, and the team worked diligently until my home was heated again.
I felt valued as a customer and appreciated the honesty, expertise, and respect demonstrated by all. I am truly grateful for the service and support provided by Comfort Union. A sincere thank you to everyone involved.
According to the EPA, indoor air can be 2-5 times more polluted than outdoor air, with allergens, pollutants, and pathogens like mold spores, dust, and bacteria.
Allergens

Pathogens
Bacteria, viruses, and mold spores.
Skin Irritation
Smoke, VOCs, and household chemicals.
Cleaner Air, Healthier Living with HEPA and Media Filters
HEPA Filter
HEPA (High-Efficiency Particulate Air) filters capture 99.97% of particles as small as 0.3 microns, including pollen, pet dander, and smoke particles.
HEPA filters are used in hospitals and clean rooms, showing their reliability in removing harmful particles from the air.
Media Filter
Media filters provide deep filtration layers, trapping large particles like dust and hair while reducing airflow resistance.
These are ideal for homeowners who want enhanced air filtration with less frequent replacements compared to standard filters.
What Type of Furnace Filter is Right for Your Home?
DISPOSABLE FIBERGLASS
Disposable fibreglass furnace filters are generally the cheapest and lowest quality furnace filters available. These are best used for filtering larger particles, such as during home renovations.
DISPOSABLE PLEATED
Disposable pleated filters are the most common type of furnace filter used in homes. Pleated filters are denser than fibreglass filters, and their wavy design creates more surface area to capture dust.
PERMANENT REUSABLE
Permanent washable furnace filters have a lot of perks if you want to commit to the cost and maintenance. They last an average of 5 years with proper care, and should be checked and cleaned regularly.
