For a 2 car garage with 500 sq ft to 700 sq ft, the estimated heater size is 30,000 to 45,000 BTUs. For a 3 car garage with 750 sq ft to 900 sq ft, the estimated heater size is 45,000 to 55,000 BTUs. The height of your ceiling will impact the size of the
What is the right size garage heater for a two car garage? To heat an average two car garage, you'll need a garage heater that is capable of heating roughly 6,000 - 9,000 cubic feet of air. We recommend getting a 30,000 - 50,000 BTU garage heater to get your two car garage to a comfortable temperature.
Here's a rough guide to determining the BTU requirement based on your garage's size: One-car garage (150-300 sq ft): 6,000 – 9,000 BTUs. Two-car garage (400-600 sq ft): 9,000 – 12,000 BTUs. Three-car garage (600-900 sq ft): 18,000 – 24,000 BTUs.
Because a two-car garage has larger square footage, usually 500 feet or more, you'll need a 12,000 BTU system.
For a 1 car garage with 200 sq ft to 300 sq ft, the estimated heater size is 15,000 to 25,000 BTUs. For a 2 car garage with 500 sq ft to 700 sq ft, the estimated heater size is 30,000 to 45,000 BTUs. For a 3 car garage with 750 sq ft to 900 sq ft, the estimated heater size is 45,000 to 55,000 BTUs.
Underfloor radiant heating is one of the best garage heater ideas. Electric radiant heating systems consist of cables laid under the flooring. The cables produce heat which radiates upward to warm the garage area evenly and consistently at lower temperatures than other systems, without leaving cold spots.
In the case of an undersized heat pump, the rooms closest to the system will be warmer during winter, while those further away will be colder. If you have an oversized system, failing to finish a temperature regulation cycle results in varying temperatures in different rooms in your home.
Installing a mini-split AC unit may well be the best way to cool a garage. While a ductless air conditioner (single-zone cooling-only unit) for your garage may be a good cooling option, if you want to be comfortable on the coldest days of winter, you should opt for a full mini-split heat pump system.
12,000 BTU – ~550 sq. ft to ~800 sq. ft. 15,000 BTU – ~750 sq.
Portable air conditioners can rapidly bring down the temperature in a garage. They are ideal for situations in which you need only a modest amount of cooling.
One-car garage (200-400 sq ft): 9,000-12,000 BTU. Two-Car Garage (400-600 sq. ft.): 12,000-18,000 BTU. Three-Car Garage (600-800 sq.
The most cost-effective method to heat a garage is often through insulation and sealing gaps first, as this reduces the amount of heat required. Once that's done, portable electric heaters have the lowest initial cost outlay.
A standard 2-car garage often measures from 24×24 (576 sq. ft.) to 24×30 (720 sq. ft.).
All central heat pumps are measured in tons, and every one ton is equal to 12,000 BTUs. This means that a 1,200-square-foot home would usually need either a 4.5- or 5-ton heat pump. We usually wouldn't recommend going with a 4-ton unit in this case.
An oversized HVAC system cycles on and off more frequently than necessary. This short-cycling leads to increased wear and tear on components, reducing the overall lifespan of the system. It can also result in uneven heating or cooling, creating uncomfortable hot or cold spots in different areas of your home.
If you're ready to upgrade your HVAC system, heat pumps are the best choice for your home, your budget, and the planet. That's why, as of 2022, more homeowners are choosing to buy heat pumps instead of gas furnaces. But getting a heat pump is a big decision. It's worth thinking about it from all the angles.
An uninsulated garage door is perhaps the biggest culprit for heat loss in your garage, as there is no barrier to slow the heat transfer out of your garage. In order to protect your garage from heat loss, you need a door with insulation.
Additionally, if the garage contains items that absorb heat, such as vehicles or tools, they can release that heat into the surrounding space, further contributing to the increase in temperature inside the house.
Furnace Replacement Costs by Capacity
Here are the usual furnace capacities you will come across: 40,000 to 60,000 BTU furnaces: These are suitable for heating homes up to 1,200 square feet. Replacing such a furnace ranges between $2,000 and $3,000.
An oversized furnace causes excess wear and tear, higher energy bills, and more problems (and expenses!) that make it tough to stay warm in the winter. This article goes over how to tell if the furnace installed in your home is too big.
