How long does a hot water tank last?

A traditional tank water heater typically lasts 8-12 years, while tankless units can last 15-20 years with proper maintenance. If your tank is over 10 years old or showing signs of rust or leaking, it's time to consider replacement.

Tank vs. tankless — which is better?

It depends on your needs. Tank heaters have lower upfront costs and simpler installation. Tankless units cost more initially but provide endless hot water, lower energy bills, and last longer. Our technicians will help you decide based on your household size and budget.

How much does hot water tank installation cost?

Hot water tank installation in Calgary typically ranges from $1,500 to $3,000 for a standard tank unit, and $3,500 to $6,000+ for a tankless system. Price varies by capacity, brand, and installation complexity. We provide free estimates.

Why is my hot water rusty or discoloured?

Rusty hot water usually indicates corrosion inside the tank, often caused by a failing anode rod. If only the hot water is discoloured (not cold), the tank likely needs attention. Contact us for an inspection — catching this early can prevent leaks.

Can you install a tankless water heater in an older home?

Yes! Tankless installation in older homes may require gas line upgrades or electrical modifications, but it's absolutely doable. Our technicians assess your home's infrastructure and handle all necessary upgrades for a safe, code-compliant installation.

Air Force was so good to deal with. Ivan, Dima and the crew did such a clean job installing our Furnace, AC and hot water tank. They were fast and easy to deal with, and did a spectacular job installing everything. Would definitely recommend them to anyone.

I had an exceptional experience with Air Force Heatng and Air Conditioning Inc.! From start to finish, their service was top-notch. The technicians were punctual, courteous, and highly skilled. They installed my furnace and AC, leaving them in pristine condition. I was impressed by their attention to detail and professionalism. They provided valuable tips for maximizing efficiency. I highly recommend this company for anyone in need of a their services. Their outstanding work and friendly approach make them stand out from the rest! Dec 30, 2025 I had an excellent experience with Air Force Services. Two technicians came to my home to replace the hot water tank, and they did a fantastic job. They were fast, professional, and very polite, and they took the time to clearly explain everything they were doing and answer my questions. This is the second time I’ve hired Air Force Services, and once again the service was extremely efficient and reliable. I really appreciate their professionalism and quality work, and I would absolutely recommend them.

Airforce and its owner, Ivan, are excellent, they installed 2 gas heaters for my garages, 1st one in September 2023, 2nd one just 2 weeks ago! Ivan is professional, always prepared well before he came, arranged things and people in details as gas heating can be so important and also can be dangerous! Ivan, his company have done good jobs for me 2 times, the gas heater served me very well in 1st garage, actually installed gas heater in that garage helped me in a way have sold the house in September this year! The 2nd heater working in my brand new garage is so far so good! I would recommend Ivan, his company to my family, my friends, and to all! They are good, not easy to find them any more in Calgary from my experience.
