Cold showers and leaking tanks don’t wait for a convenient day. Lower Mainland HVAC replaces and installs gas tank and tankless water heaters across Surrey, Langley, Delta and the Lower Mainland. As licensed gas fitters, we do the gas line, venting and permit ourselves, so you don’t need a second trade.
What we do
- Tank replacement. Same-size gas tank swaps (40–75 gallon), usually done in three to four hours.
- Tankless installation. Wall-mounted on-demand heaters for endless hot water and more floor space.
- Tank-to-tankless conversions. Including gas line upsizing, new venting and a condensate drain.
- Gas line and meter checks. A tankless heater burns up to 199,000 BTU at full fire. We add up every appliance on your system so nothing runs short.
- Descaling and service. A yearly flush keeps a tankless at full output. FortisBC pays up to $50 back on tankless servicing.
- Repairs. Pilot and thermocouple faults, error codes, leaking valves and no hot water.
Tank or tankless?
| Gas tank | Gas tankless | |
|---|---|---|
| Hot water supply | Runs out when the tank empties | Endless, up to its flow rate |
| Lifespan | 10–12 years | 20+ years with service |
| Space | Floor space in a closet or garage | Wall-mounted |
| Upfront cost | Lower | Higher |
| Best for | Smaller households, quick swaps | Larger families, soaker tubs, suites |
Signs your water heater is done
- Water pooling around the base of the tank
- Rusty or brown hot water
- Rumbling or popping from the tank
- Hot water runs out faster than it used to
- The tank is 10–12 years old or more
- The pilot keeps going out
How it works
- Tell us what you have. A photo of the tank’s label and the spot helps us quote quickly.
- Quote. One written price, including the permit.
- Install. Old tank drained and removed, new unit installed, gas line leak-tested, venting to code.
- Test and walk-through. We set the temperature and show you the shut-offs.
What does a new water heater cost?
| Job | Typical range |
|---|---|
| 40–50 gal gas tank, replaced | $2,200–$3,800 |
| 60–75 gal or power-vent tank | $3,500–$5,500 |
| Tankless, replacing a tankless | $3,800–$5,500 |
| Tank-to-tankless conversion (incl. gas upsizing) | $4,500–$7,500 |
| Tankless descale and service | $200–$300 |
Lower Mainland considerations
- Seismic straps. BC code requires water heaters to be strapped. We strap every tank.
- Water hardness. Most Metro Vancouver water is soft, which is good for tankless units. Fraser Valley wells can be harder and need more frequent descaling.
- Garages and crawlspaces. Many Surrey homes have the tank in the garage. We add a drain pan and check for vehicle protection.
