How much does it cost to replace a water heater in Calgary?

A standard 40-gallon tank-for-tank replacement is $1,500–$2,500 fully installed including removal and permit. A 50–60 gallon or higher-recovery gas unit lands $2,000–$3,500. A tank-to-tankless conversion runs $4,000–$6,500 depending on venting and gas line modifications.

When should I replace instead of repair?

Replace if the tank is 10+ years old, has visible rust at the connections, is leaking from the tank body itself, or if the repair quote exceeds half the price of a new install. Past 10 years the steel liner is on borrowed time — repairing buys months, replacing buys 8–12 years.

How fast can you replace a leaking water heater?

Same-day swaps are usually possible if you call before noon. We stock the most common 40 and 50-gallon Bradford White and John Wood tanks on the trucks and at the warehouse, so for emergencies (active leaks, no-hot-water households) we can have a new tank installed and commissioned the same afternoon.

Should I switch from a tank to a tankless when I replace?

It depends on your demand and how long you'll stay in the home. Tankless costs $1,500–$3,000 more up front but saves on monthly bills, lasts 15–20+ years vs 8–12, and gives you unlimited hot water. If you're staying 5+ years it usually pays back. We'll quote both options on the visit.

Do you handle the permit and old tank disposal?

Yes — every replacement quote includes the City of Calgary gas permit, inspection scheduling, and old tank removal/recycling. You don't lift a finger and you have closed paperwork for insurance and resale.

What warranty comes with a new water heater?

Standard tanks ship with a 6-year manufacturer warranty on the tank and parts. Premium tanks (and most tankless units) come with 10–12 year coverage. We back our installation labour for the first year — typical industry practice.

Good experience with Air Force Heating and Air Conditioning overall. Had a Gree heat pump installed and Ivan, Dima and Rustam did the job. They showed up on time, were polite, and kept things clean during install. System is working good and you can feel the difference already. Only small thing is I had to ask a couple questions after they left to understand all the settings, but not a big deal. Solid service, would recommend.

I just had an air conditioning unit installed at home, and I couldn’t be more thrilled! The team was fantastic—super efficient and committed to quality at every step.

Our furnace went out during a cold snap and they were here within hours. Professional, friendly, and had us back up and running in no time. If you want it done right the first time, call these guys.

Eight Signs It's Replacement Time

A water heater rarely fails without warning — but the warning window is short. Spot these signs early and you'll replace on your schedule, not at 2 AM with a flooded basement.

Tank is 10+ years old
Visible rust at the connections or base
Water pooling under the tank — even slow leaks
Rusty hot water from every tap
Repeat repairs in the same year
Heating element or thermostat failed twice
Repair quote is more than half the cost of new
Loud popping or rumbling that won't quiet after a flush
