The four jobs
Residential HVAC Calgary covers four jobs
The work splits four ways, each landing at a different stage of the build. TNT runs all four out of one shop in southeast Calgary.
Legal & secondary suites
Heating and ventilation kept independent of the main home, with ducting of its own and its own thermostat.
Renovations
Heat runs rerouted and ductwork resized when the walls move, and equipment relocated properly rather than shuffled.
New builds & infills
The real house measured, duct design laid into the structure, and every room checked at commissioning.
Legal & secondary suites
Do legal suites in Calgary need their own furnace?
Usually yes. A legal secondary suite needs heating and ventilation that work independently of the main home. In most Calgary basements that means a second furnace, its own ducting and its own thermostat.
What independent means
The suite cannot tee off the trunk duct feeding the house above. It needs its own heat source, ducting that serves only the suite, and a thermostat the tenant can reach.
Ventilation is separate
Ventilation is the half that gets forgotten until the inspection. Where continuous ventilation is called for, that is an HRV, a heat recovery ventilator that keeps the heat in.
Hot water needs sizing too
A suite adds a second shower, a kitchen and often a laundry to a tank sized for one household. That belongs with our hot water tank replacement Calgary work.
Older suites and new ones
Converting a basement that holds a registered suite is a different conversation from a new application. We design to what your permit asks for, not to a general rule.
Basement developments
Basement development heating and ductwork
An open basement lives on what spills off the trunk. Once it is framed into rooms, each room needs its own branch and return.
- Supply branch runs sized room by room, not to the easy joist bay
- Returns added with the framing, because a bedroom with no return goes stuffy the second the door shuts
- Furnace load and duct static pressure read before any tin is cut
- Often the honest finding is that the furnace is fine and the ductwork is the bottleneck
Permits & inspections
Permits, inspections and residential HVAC Calgary
A basement development, a suite and a new build are all permitted, inspected work. We apply for the mechanical permit rather than leaving it on your list.
Whose permit is whose
The building permit for the space sits with you or your contractor. The mechanical permit for gas, venting and ductwork sits with us, priced into the quote.
Inspected before drywall
An inspector has to see the duct runs, the venting, the gas piping and the combustion air while they are still visible. A fail after drywall means demolition.
What you are left with
A permit closed against your address, and a written scope saying what went in and where. Two year warranty on the labour stands behind the workmanship.
How it works
What happens on a residential HVAC job in Calgary
The same three steps for one basement bedroom or a whole infill. Nothing priced unseen, nothing left half finished behind the drywall.
We look at the plan first
Drawings if you have them, the mechanical room either way. We work out what the project adds in load and what the furnace and ductwork can carry, before anyone talks numbers.
Written scope, permit included
An itemised quote in writing, and the City of Calgary mechanical permit taken care of as part of the job. Nothing is booked until you have said yes to a number you have seen.
Rough-in, finish, commissioning
Drop sheets go down along the route in and out, and we cut where the design says. The loudest part does not last all day, and the site is swept before we leave.
The quote is written on the visit, not posted to you three days later. If your system is down right now, skip the form and call. 24/7 emergency service, an owner answers or calls back.
Residential HVAC timeline
When does residential HVAC in Calgary need to happen?
A basement schedule belongs to the framers and the drywallers, not to us. What we can tell you is the three points in the build where we have to be there.
At drawing stage
Bring us in while the layout is still on paper. Nothing is cut and nothing is booked, and the runs get designed around the rooms you actually want.
Rough-in, at framing
One visit before the drywall goes on. The branch runs, the returns, the gas piping and the venting all go in and stay visible for the inspection.
Finish, then sign-off
A second visit once the space is finished, to set and fire the equipment, measure the airflow room by room, and leave you the paperwork for it.
Paying for it
Paying for residential HVAC in Calgary over time
A basement development or a suite conversion is a four-figure decision landing in the middle of a project that is already costing money.
Monthly promotions on installs
Promotions on new installations change through the year, so ask what is running when you book. Once approved, you sign off directly with the lender.
15% off on every new install
The discount comes off the price we quote you. There is no list price marked up first so the saving looks bigger than it is. Ask about it when you book.
The full price in writing first
Equipment, labour, and what is included, itemised before any work starts. If something turns up on the day, you decide before we carry on.
Two year warranty on the labour
If our workmanship is at fault we come back and fix it, no argument. The equipment carries its own manufacturer warranty on top of that.
Subject to a third-party credit check. Approval and terms are set by the lender, not by us, and we will tell you what you qualify for before you commit.

TNT Heating & Air Conditioning
5.0Rated on Google
Every review TNT has ever received is a five star review. These are Calgary homeowners whose residential HVAC work we did.
TNT installed the furnace system on our new build, and then we proceeded to get our AC with TNT as well. Jamie was super responsive, kind, and informative… In addition to being fairly priced.
Christina Golubic
Jamie and his team provide incredible expertise. They gave me consultative choices to improve my existing system, and clean installation done right… all at a fair price.
Trevor
Great job and great price.
Murray Jonasson
It was -30 kind of winter day… other companies asked for us to wait over 24 hours… Jamie came to service our non heating furnace within an hour and fixed the problem quickly.
Adelia Timirboulatova
Amazing service. I would not go with anyone else. Jamie tells you the truth, stands by his work and follows up.
Robert Milne
Not only was TNT very reasonably priced, they fit me into their busy schedule during the heat spell and got me all set up in no time.
John Klassen
Jaime was professional and kept me informed throughout the entire process… His technician arrived on time, was knowledgeable, and took the time to answer all of my questions.
Glenn Jefferies
Would highly recommend. Check with TNT before making any decision regarding heating or AC install. Believe me. They were amazing.

Cooling & zoning
Cooling and comfort, decided while the walls are open
Residential HVAC in Calgary is not only a heating conversation, and a development is the cheapest moment this house will ever offer to fix the rest of it.
The cheapest time to add cooling
Adding a coil during a basement development costs a fraction of retrofitting it two summers later. If the furnace is going anyway, price a heat pump installation Calgary at the same time.
Why the upstairs never matches
Heat rises and one thermostat reads one room. A single-zone system serving three storeys is asked to satisfy three demands from one measurement.
The cheap fixes come first
Balancing the existing dampers costs nothing and is sometimes the whole answer. Adding returns where the air has no way back is the most common real fix.
When zoning is the real answer
Its own dampers and thermostats, or a variable-speed blower holding a low continuous circulation. For cooling on an existing house, AC installation Calgary is the page.
What it costs
What drives residential HVAC cost in Calgary
Square footage is the wrong unit to price this in. What it costs comes down to what the house already has, and these six things decide it.
How many rooms need their own supply
A single open rec room is one branch. Two bedrooms, a bathroom and a wet bar is four, each needing a route the joists will actually take.
Whether the returns can reach the trunk
Supply is the easy half. Getting air back is what decides whether the job is straightforward or needs a new return path cut through framing.
Joist space against a bulkhead
Runs that fit inside the joist space disappear into the ceiling. Runs that do not need a bulkhead, which is a headroom decision as much as a mechanical one.
Spare capacity in the existing furnace
Sometimes the furnace you have carries the new load comfortably. Sometimes it does not, and a suite may want its own unit regardless of capacity.
Whether hot water has to change
Adding a bathroom or a suite often pushes demand past what the current tank manages. Upsizing, or splitting the supply, belongs in the plan rather than a surprise.
The mechanical permit and inspection
Applied for as part of the job and itemised on the quote rather than folded into a round number. A quote with no permit line is worth asking about.

Residential HVAC Calgary FAQs
Residential HVAC Calgary questions
The nine that come up when a basement plan lands on the kitchen table, answered straight.
- There is no honest single figure, because the number is driven by the job rather than by the square footage. What moves it: how many new rooms need supply runs, whether returns can reach the existing trunk, how much joist space or drop ceiling there is to work in, what spare capacity the furnace has, and whether gas, venting or a mechanical permit are in scope.
You get an itemised written quote before anything is booked, and there is currently 15% off new installs. - Yes, and we apply for it. A basement development in Calgary is permitted, inspected work, and the mechanical permit covering the ductwork, the gas and the venting is part of our scope rather than a task left on your list.
The building permit for the space itself usually sits with the homeowner or the general contractor. We handle the mechanical side, do the work to pass the inspection that follows, and leave you the documentation. - Only if the furnace ends up undersized or the duct system is too restrictive for it. A unit running longer cycles inside its design range is not being harmed. A unit fighting high static pressure, or short-cycling against a load it cannot meet, is.
That is a ductwork problem more often than an equipment one, which is why a residential HVAC job in Calgary starts with the load and the static pressure rather than with the equipment. - Sizing beats badge. A correctly sized, correctly vented mid-range furnace will outperform a premium unit that is too big for the space, because an oversized furnace short-cycles, and short-cycling is what makes a small suite feel drafty and noisy.
We put the make and model in the written quote so you can see exactly what is going in, and we will explain why that one suits the load instead of pointing at a brand tier. - Two year warranty on the labour. If our workmanship is what failed, we come back and put it right. The equipment carries its own manufacturer warranty on top of that, and we register it at install so the cover actually starts.
The written scope records what was installed and where, which is the document that matters if anything ever needs looking at again.
- Call (403) 408-6136 rather than filling in a form. 24/7 emergency service, an owner answers or calls back, so you are explaining the problem to someone who can dispatch a technician rather than to a script.
A breakdown in the middle of a renovation is a service call, not a project, and it gets treated that way. We will not promise an hour we cannot keep, but you will get a straight answer on the phone about when we can be there. - Only if the numbers say so. A development is a sensible moment to replace a furnace that is genuinely at the end of its life, because the access is open and the ductwork is being opened up anyway. On its own it is not a reason.
We check the spare capacity and the static pressure first. If the existing unit carries the new load and the ducts are the constraint, the honest answer is to fix the ducts and keep the furnace. - We arrive with the drawing, walk the framing with you, and mark the runs before anything is cut. Drop sheets go down along the route in and out.
Then the branch runs, the returns, any gas piping and the venting go in, get sealed and strapped, and get left visible for the inspection. The site is swept before we leave. The equipment itself is set and fired later, at finish. - Financing yes. Rebates depend on the equipment and on what is running at the time, so we do not publish amounts here: programs open and close, and a figure on a website ages badly.
The current offers, the financing terms and whatever rebates apply to your equipment are set out on our HVAC financing in Calgary page. Ask when we quote and we will tell you what your job qualifies for.
