AC Installation Calgary
High-efficiency central air conditioning and AC installation built for Calgary’s hot summers and wildfire smoke season, by certified technicians who’ve served local families since 1995.
Built for Calgary's Unique Climate
Calgary summers hit 30°C+ — but it’s not just the heat. Wildfire smoke drifting in from BC and Alberta forests has made indoor air quality a growing concern. A properly installed, high-efficiency AC system does double duty: it keeps your home cool and filters smoke particles when windows need to stay closed.
Calgary regularly sees weeks of 28–34°C highs from late June through August. Without AC, indoor temperatures can exceed 35°C — dangerous for children, seniors, and pets. A properly sized system maintains 21–23°C consistently, even on the hottest days.
Smoke from BC and Alberta wildfires regularly pushes Calgary’s air quality into the Moderate to High Risk range from June through September. A sealed, air-conditioned home with quality MERV-13 filtration keeps smoke out — unlike open windows. In 2024, 70% of our installs included upgraded filtration for exactly this reason
Many of Calgary’s inner-city neighbourhoods — Inglewood, Crescent Heights, Bridgeland, Mount Pleasant — were built before central air was standard. We assess every home individually and recommend the right cooling solution for your layout, age, and budget. No guesswork, no one-size-fits-all approach.
Calgary homeowners upgrading to a high-efficiency AC (14.5+ SEER2) may qualify for rebates through ENMAX, EPCOR, or ATCO. Our team identifies every applicable rebate during your free in-home estimate and handles the paperwork — so you don’t leave money on the table.

AC Installation Cost in Calgary — 2026
In Calgary, a new air conditioner installation typically ranges from $4,300 to $8,600 depending on system type, home size, and brand. Here’s what to expect — no surprise fees, ever
| System Type | Efficiency Rating | Typical Cost (Installed) | Best For |
|---|---|---|---|
| Central AC — Standard | 15–16.5 SEER2 | $4,300 – $6,500 | Homes with good existing ductwork |
| Central AC — High Efficiency | 17–19 SEER2 | $6,500 – $8,600 | Energy-conscious homeowners |
| Ductless Mini-Split — Single Zone | 18–22 SEER2 | $3,800 – $6,200 | Older homes, additions, suites |
| Ductless Mini-Split — Multi-Zone | 18–24 SEER2 | $5,500 – $9,500 | Multi-room or whole-home ductless |
| Duct Repairs / Upgrades (if required) | No Rating | – | Added when existing ducts need work |
Home Size & Layout
Larger homes need higher-tonnage units. Multi-level homes or difficult access can increase installation time and labour costs.
Efficiency (SEER2 Rating)
Higher SEER2 units cost more upfront but reduce monthly ENMAX/EPCOR bills. Upgrading from 14.5 to 19 SEER2 typically saves $30–$60/month in summer.
Existing Ductwork
Older Calgary homes often need duct repairs before adding central AC. We inspect ductwork during every free estimate and quote any repairs upfront.
Central AC vs. Ductless Mini-Split:
Which Is Right for Your Calgary Home?
The right system depends on your home’s age, layout, and existing ductwork. Here’s how to think about it — and we’ll confirm the best fit during your free in-home estimate.
Central Air Conditioning
Best for homes built after 1975 with existing furnace ductwork
- Whole-home cooling through existing vents
- Invisible — no wall units or indoor heads
- Pairs directly with your furnace blower
- Lower upfront cost when ductwork is already in place
- Widely preferred in newer Calgary suburbs (Tuscany, Legacy, Mahogany)
Ductless Mini-Split
Best for older Calgary homes, infills, additions, and basement suites
- No ductwork required — installed in 4–6 hours
- Up to 30% more energy efficient than central AC
- Zoned control — cool only the rooms you use
- Ideal for Inglewood, Bridgeland, Crescent Heights, Mount Pleasant
- Heat pump models also heat in winter — dual-purpose
Sizing rule of thumb:
A properly sized central air conditioner needs approximately 1 ton of cooling capacity per 600–700 sq ft. A 2,000 sq ft Calgary home typically needs a 3-ton unit. We conduct a full heat load calculation on every free estimate — so you never end up with an oversized or undersized system.

Calgary Permit Requirement:
The City of Calgary requires an electrical permit for all new AC installations. Working without a permit is illegal, voids your manufacturer warranty, and can cause issues when selling your home. Comfort Union pulls the permit, coordinates with the city inspector, and ensures your installation is 100% code-compliant, included in our quoted price

Upgrading from an older 10-SEER unit to a new 16.5+ SEER2 system typically reduces cooling costs by 30–50%.
What Calgary Homeowners Are Saying
I was referred to Comfort Union by a friend who had recently installed an air conditioning unit, and I’m so glad I took their recommendation. From the moment they quoted the job in person to the completion of the installation the following week, Comfort Union provided excellent service. The pricing they offered was competitive, and their team was easy to deal with throughout the process. I appreciate their hard work. Highly recommended for all you HVAC needs!
Comfort Union is a hidden gem. The team is very caring about their customers. I had them install an A/C unit for me over the summer and it was quick, affordable and reliable. The team cleaned up after themselves and kept my property clean. I will use them for all of my HVAC needs.

AC Installation Calgary — Common Questions
How much does AC installation cost in Calgary?
In Calgary, air conditioner installation typically costs between $4,300 and $8,600 for a central AC system, and $3,800 to $6,200 for a single-zone ductless mini-split. The final price depends on the system type, the size and layout of your home, the efficiency rating (SEER2), and whether any ductwork repairs are needed. Comfort Union provides a written, fixed-price quote after a free in-home estimate — so there are no surprises on installation day.
Do I need a permit for AC installation in Calgary?
How long does AC installation take?
Most central AC installations are completed in a single day — typically 6 to 8 hours depending on home size and ductwork condition. Ductless mini-split installations for a single zone take 4 to 6 hours. Multi-zone ductless systems can take 1 to 2 days. We’ll confirm the expected timeline during your free estimate and work around your schedule.
What size AC do I need for my Calgary home?
A common rule of thumb is 1 ton of cooling capacity per 600–700 sq ft. A 1,500 sq ft home typically needs a 2–2.5 ton unit; a 2,000 sq ft home typically needs 3 tons. However, the right size also depends on ceiling height, insulation quality, window area, and home orientation. Comfort Union conducts a full heat load calculation on every job to ensure accurate sizing — oversizing wastes energy and causes humidity problems, while undersizing means your system runs constantly.
Central AC or ductless mini-split — which is better for Calgary homes?
It depends on your home. Central AC is ideal if you have existing furnace ductwork in good condition — it’s invisible, whole-home, and cost-effective when ducts are already there. Ductless mini-splits are the better choice for older inner-city Calgary homes (Inglewood, Crescent Heights, Bridgeland, Mount Pleasant) where no ductwork exists, or for additions, basement suites, and garage conversions. Ductless systems are also 20–30% more efficient when cooling specific zones. In 2024, 70% of our Calgary installations were ductless.
Can a new AC system help with wildfire smoke in Calgary?
Yes — significantly. During wildfire smoke events (increasingly common in Calgary from June–September), a sealed, air-conditioned home with quality filtration is one of the most effective defenses against indoor air pollution. Modern AC systems circulate air through your furnace filter, and upgrading to a MERV-13 filter alongside your new AC installation can remove the majority of fine smoke particles. Unlike opening windows to cool down, running your AC keeps smoke out entirely.
What AC brands does Comfort Union install?
We are a Carrier Authorized Dealer and primarily install the Carrier lineup — including the Comfort Series (16.5 SEER2), Performance Series (19 SEER2), and Infinity Series (24 SEER2). Being an authorized dealer means our technicians are factory-trained on Carrier equipment and your manufacturer warranty is fully valid. We can also advise on other brands depending on your specific situation — just ask during your estimate.
Does Comfort Union handle AC replacement in Calgary?
Yes — AC replacement is a significant part of what we do. If your current system is 10+ years old, requires frequent repairs, or isn’t keeping up with summer heat, it’s likely more cost-effective to replace it. During your free estimate, we’ll assess your existing unit, explain your options honestly, and only recommend replacement if it genuinely makes financial sense for you. Our replacement process follows the same steps and transparent pricing as a new installation.
