Unit heaters
Unit Heater Installation and Repair in the GTA
A unit heater heats a garage, workshop, warehouse or commercial space directly, without ductwork. We size, install and repair natural gas unit heaters, including power-vent models, and handle the venting and gas connection as part of the job.

Not sure what size you need?
Tell us the size of the space, ceiling height and how well it is insulated. We recommend a heater output that heats it properly without oversizing.
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.

Unit heaters: common questions
What size unit heater do I need?
It depends on the floor area, ceiling height and insulation. We size from these details so the heater is neither too small to keep up nor oversized.
Does a unit heater need venting?
Gas unit heaters need to be vented properly. Power-vent models vent through a sidewall or roof; we confirm the right arrangement before installing.
Do you install them in garages and commercial spaces?
Yes. We install in residential garages and workshops as well as commercial and industrial spaces across the GTA.
