Pool Heater Installation and Repair in the GTA
A gas pool heater lets you swim earlier in spring and later in fall. We size, install and repair natural gas pool heaters, including the gas line and venting, so the heater runs safely and reaches temperature quickly.

Need a gas line first?
Pool heaters draw a lot of gas. We check your meter and gas line capacity before quoting so the heater gets the supply it needs.
How a visit works
Step 1
Call or book online
Tell us the equipment and what it is doing. If it shows an error code, have it ready; it often tells us which part to bring.
Step 2
Diagnosis and a clear price
A technician tests the system, shows you what failed and gives you the price. You decide before any work starts.
Step 3
Fixed, tested, cleaned up
We finish the repair or install, run the system through a full cycle and leave the area as we found it.

Pool heaters: common questions
How big a pool heater do I need?
It depends on your pool volume, how much you want to raise the temperature and how quickly. Send us the pool size and we recommend a heater output.
Do I need a new gas line?
Often yes, because pool heaters use more gas than most appliances. We check your existing line and meter capacity during the estimate.
When should I book installation?
Before pool opening in spring is the busiest time, so booking early in the season avoids delays.
