No hot water, a leaking tank, or a water heater that's past its prime? Reid Pro repairs, replaces, and installs hot water tanks and tankless water heaters for homes and businesses across Lethbridge and Southern Alberta, with the gas fitting and permits handled.
Water Heater and Hot Water Tank Repair
No hot water, not enough of it, water that runs hot then cold, a leak, or a tank that rumbles and pops. Our certified technicians find the cause and fix it, and tell you straight when a repair isn't worth the money.
Hot Water Tank Replacement
When it's time for a new tank, we help you choose the right size and model for your household, install it to all safety standards, and haul the old one away.
Tankless Water Heater Installation
On-demand hot water that doesn't run out mid-shower, from a wall-mounted unit that frees up floor space and only runs when you need it. We size the unit, handle the gas line and venting, and set it up properly.
Maintenance and Inspections
Preventative maintenance extends the life of a tank or tankless system and keeps it running efficiently. Buying a home or planning a renovation? We can look at what's there and tell you how much life it has left.
Brands We Install
We service all major brands. For new installs we most often recommend Bradford White and John Wood hot water tanks, and Navien and Noritz tankless water heaters.
Gas Fitting and Permits Handled
In Lethbridge, a new gas water heater is installed under a gas permit, and only a certified gasfitter can get one. Our licensed team pulls the permit and books the inspection as part of the job.

Recent work
Old Tank Out, Tankless In
An aging hot water tank replaced with a wall-mounted tankless system in the same mechanical room, alongside a new furnace. More floor space, and hot water that doesn't run out.


Hot Water Tank or Tankless?
Both do the job. The right one depends on your household, your space, and your budget, and we'll walk you through it when we quote.
Hot Water Tank
- Lower cost up front
- Usually a straightforward swap for the tank you have
- Stores a set amount of hot water, so a busy morning can drain it
- Takes up floor space in the mechanical room
Tankless Water Heater
- Heats water on demand, so it doesn't run out
- Mounts on the wall and frees up floor space
- Only burns gas while a tap is open
- Costs more up front, and can need gas line or venting changes
Signs Your Hot Water Tank Is Due for Replacement
- It's getting old. Most hot water tanks last 8 to 12 years.
- Rusty or discoloured hot water
- Rumbling or popping while it heats
- Water pooling around the base of the tank
- Hot water that runs out faster than it used to
A leak at the base usually means the tank itself has failed, and that calls for a replacement instead of a repair. If you're seeing any of these, it's worth getting it looked at before it fails on a cold morning.
Water Heater FAQs
How long does a hot water tank last?
Most hot water tanks last 8 to 12 years. Water quality and maintenance make a difference, and we'll give you an honest read on yours.
Should I repair or replace my water heater?
If the tank is fairly new and the problem is a part, a repair usually makes sense. If it's past 10 years old, leaking from the tank itself, or needing repeat repairs, replacing it is usually the better money.
What size hot water tank do I need?
It depends on how many people are in the home and how much hot water you use at once. We'll help you choose the right size and model when we quote.
Is a tankless water heater worth it?
It can be. Tankless costs more up front, but it doesn't run out of hot water, it saves floor space, and it only runs when you need it. We'll tell you whether it makes sense for your home.
Do I need a permit to replace a gas water heater in Lethbridge?
A new gas water heater is installed under a gas permit, and only a certified gasfitter can get one. We take care of the permit and inspection for you.
Do you offer after-hours water heater repair?
