Bridgeview’s Garage Heater Installation Specialists

Size depends on square footage, ceiling height, insulation, and how often the door opens during use, factors that go beyond a simple size chart. A poorly insulated two-car garage needs considerably more output than a small, well-sealed workshop of similar dimensions, and a door that opens frequently loses heat faster than one that stays closed most of the day. We size this during the estimate rather than using a general chart, walking through how the space is actually used day to day. Getting the size right matters since an undersized unit never quite catches up, while an oversized one wastes energy running more than necessary.

It depends on the space and how it’s used. Gas-fired units heat larger garages more efficiently and tend to cost less to run over time, but they need proper venting installed as part of the job. Electric units install faster since there’s no venting required, and they work well in smaller or better-insulated spaces where a lower output is sufficient. Infrared heaters are another option for spaces where quick, targeted warmth matters more than heating the whole room evenly. A technician can walk through which fits your garage based on size, insulation, and how the space gets used.

Cost depends on unit type, size, and whether gas or electrical lines need to be run to the space, which varies significantly between a detached garage and one attached to the house. Gas-fired units typically cost more to install due to venting requirements, while electric units tend to have a simpler installation process. We provide a free estimate after assessing the garage, including its current electrical or gas access. Financing is available for installations of any size, which helps since garage heaters are often installed alongside other workshop or storage improvements happening around the same time.

In some cases, yes, if the garage is attached and the ductwork can reasonably extend to it without major modifications. Detached garages typically need a standalone unit since running ductwork or piping across that distance usually isn’t practical or cost-effective. Even attached garages sometimes benefit more from a dedicated heater, since tying into the main system can affect how efficiently the rest of the house heats. Our furnace installation page covers ducted options if extending an existing system makes more sense for your specific layout. A technician can assess which approach fits during the estimate.

An annual check catches most issues before they turn into a breakdown, similar to how a furnace benefits from yearly service. This typically includes inspecting the burner or heating element, checking venting on gas units, and confirming the thermostat and safety controls are functioning correctly. Garages tend to expose heaters to more dust and debris than an indoor furnace, which makes regular filter or vent checks especially important. Our maintenance plans cover garage heaters on the same schedule as other heating equipment, so this gets handled proactively rather than only after something stops working correctly.
