Garage Heaters We Install
We install the right type for your garage, your use, and your budget, not a one-size-fits-all unit.
Forced-Air Gas Heaters
The workhorse of garage heating. A ceiling-mounted gas unit heater delivers fast, powerful, economical warmth, making it the top choice for medium to large Chicago garages where a gas line is available. We install trusted units like the Modine Hot Dawg and handle the venting and gas connection.
Infrared Tube Heaters
Infrared heaters warm objects and people directly instead of heating the air, so they’re perfect for drafty garages, high ceilings, and workshops. There’s no fan blowing dust around, and the heat stays steady even when the door opens, ideal for hobbyists and mechanics.
Electric Unit Heaters
Electric heaters need no venting and install easily, making them a clean, simple option for smaller or well-insulated garages. They typically run on a 240V circuit, which we can install, and there are no combustion byproducts to vent.
Ductless Mini-Splits
A ductless mini-split heats and cools your garage in one efficient system, great if you use the space year-round. Because heat pumps lose efficiency in extreme cold, we’ll advise honestly on whether a mini-split or a gas unit is the better primary heat source for your garage.
What Size Heater Does Your Garage Need?
Getting the BTUs right is the difference between a cozy garage and a cold one. Sizing depends on your garage’s square footage, ceiling height, insulation, and how warm you want to keep it against Chicago’s cold.
As a rough guide, a two-car garage in our climate usually needs around 45,000 BTU, and a three-car garage closer to 60,000 BTU, though a poorly insulated space can need more. Rather than guess, our technicians calculate the right size for your exact garage, so you don’t overpay for an oversized unit or get stuck with one that can’t keep up in January.
One tip that saves money: insulating your garage, especially the door, dramatically reduces the heater size you need and cuts running costs.

A Reputation Built on Trust and Quality
The techs arrived exactly on time at the start of the appointment window, and quickly found the issues (dirty condenser coils, refrigerant top-off, and system sealant to address the small leak). Ramond clearly explained the impact of each along with the cost to fix, then confirmed which services I wanted and what my total would be before starting the work. I also appreciate that Ramond answered all my dumb questions about how air conditioning actually works; he's a great science teacher 🤓.
The cost was less than I expected for a next-day service (coil cleaning $239, sealant $285, and a few pounds of refrigeratant was $370).
During the payment process, the tech didn't prompt for a tip, unlike most companies. So don't forget to ask them for their Zelle/Venmo if you want to send a tip
Angelique on the phone gave clear instructions on what I needed to do before the service guys showed up. Ramod & Eric were courteous and wore shoe covers as they entered the house. They took a quick look and knew what needed to be done immediately.
As a Realtor, I’ve changed many an AC units and their prices were very fair. We ended up repairing instead of a new AC unit. The repair was less than what he originally quoted. How is that for honest service?! Amazing!
They will have to come back for a service ($99) as we ran out of time.
I can highly recommend Browns Heating & Cooling without any hesitation.
A Garage You Can Use Year-Round
A heated garage is worth far more than a place to park. Chicago homeowners use ours to power through winter as home workshops, gyms, and hobby spaces, to protect vehicles and batteries from the cold, and to keep stored items and plumbing safe from freezing.
Whether you’re finishing a detached garage, a large pole barn, or a new build, we’ll match the right heat to the space. For attached garages and larger builds, we also handle radiant floor heating and full home heating systems.
Our Installation Process
We keep it straightforward and safe. Our technician assesses your garage size, insulation, and fuel options, then recommends and sizes the right heater with upfront, flat-rate pricing.
On installation day, we mount the unit at the correct height and clearances, connect the gas line and venting or the electrical circuit, install the thermostat, and pull any required city permit. We test the system and confirm safe operation, including proper venting for gas units, before we leave.

Frequently Asked Questions
What size heater do I need for my garage?
A two-car garage in Chicago typically needs around 45,000 BTU, and a three-car garage about 60,000 BTU, though insulation, ceiling height, and how warm you want it all matter. We calculate the exact size for your garage so it heats reliably without wasting energy.
Is a gas or electric garage heater better?
Gas heaters cost less to run and heat large, cold spaces best, but need venting and a gas line. Electric heaters install more easily with no venting and suit smaller or well-insulated garages. We’ll recommend the right fit for your space and budget.
Do I need a permit to install a garage heater in Chicago?
Yes, in most cases. Hardwired 240V electric, natural gas, and propane heaters typically require a permit and should be installed by a licensed professional. We handle the entire permitting process for you.
Are garage heaters safe?
Yes, when properly installed. Gas units must be correctly vented to remove combustion gases, and every heater needs the right clearances from combustible materials. Professional installation ensures both, protecting your family from carbon monoxide and fire risk.
Will a mini-split heat my garage in a Chicago winter?
A mini-split heats and cools efficiently, but heat pumps lose capacity in extreme cold, so for a garage you use through deep winter, a gas unit heater is often the more reliable primary heat. We’ll advise on the best option for your needs.
