What Size Electric Furnace Do You Need?
To make sure you are choosing the correct electric furnace sizing for your home you will need to determine the right size ton heater and BTUs heating capability based on the square footage of your home along with the climate where you live.

|Home Size (Single Story):||Electric Furnace Output Needed (BTU per hour.):||AC Unit Size Needed:|
|1200 square ft||50,000 BTU||1.5 to 2 tons|
|1200 to 1500 square ft||55,000 BTU||2 tons|
|1500 to 1800 square ft||60,000 BTU||2.5 tons|
|1800 to 2500 square ft||70,000 BTU||2.5 to 3 tons|
|2500 to 3500 square ft||90,000 to 100,000 BTU||3.5 to 4 tons|
Electric Furnace Heaters vs. Gas Furnaces

Electric furnace installation is a pretty straightforward process and due to them not needing to be vented, they are much easier to replace than gas furnaces. They are also more quiet when operating than a gas furnace. In addition, electric furnaces can last from 20 to 30 years, while a gas furnace usually only lasts 15 to 20 years.

Other Factors that Affect Electric Furnace Installation Costs

You may also need to upgrade your current insulation if your home is not properly insulated you will lose a lot heating and cooling capacity due to heat loss. This can be caused by drafty windows and overall home insulation and may need to be discussed with your contractor.

Installing an electric furnace takes much less time to complete than that of a full natural gas furnace or oil burning furnace. This is an important advantage as it means your household will be disrupted for a shorter time as compared to the installation of other types of HVAC systems. When hiring an electric furnace installer there are a few things you can do to make the process easier:
- Ask for several bids from local electric furnace contractors in order to get the best price. Be careful to not always go with the lowest quote, as you could potentially get inferior service or equipment.
- Ask your HVAC contractors what their equipment markup is. A cheaper labor cost might include hidden markups in the electric furnace equipment price.
- Ask your furnace installer about installing a new thermostat as well. Often, newer technologies require newer devices to run them.
- Ask for a detailed cost list or proposal that outlines the entire scope of the electric furnace installation job including furnace manufacturers used with model numbers and have scheduled completion dates agreed on.
- Ask the contractor to go over your new electric furnace price quote including mathematical calculations used to size the electric furnace. Verify that their calculations are correct to avoid buying an incorrect furnace size for your home.
- Ask for name brand furnace equipment. Cheap knockoffs can be risky investments that might fail early on and leave you without heat until repaired.

Electric Furnace Maintenance
Along with scheduled visits from an electric furnace contractor, there are several steps you need to take to ensure the system operates at max efficiency. Your electric furnace works hard to funnel heated air from every room in the house and needs proper maintenance. Follow these simple steps to help your system run more efficiently:
- Before doing anything, turn off the power and unplug the system. Never work on an electric home heating system while electricity is running through the system.
- Keep yourself extra safe by wearing appropriate safety gear such as rubber gloves, rubber soled shoes, and protective eye wear such as safety goggles.
- Materials you need include a screwdriver, soft brush, several soft towels, vacuum, and a replacement filter, if needed.
- Every electric furnace system has an instruction manual. Acquaint yourself with the dos and don’ts. Read the manual from the first page to the last especially any warnings and information about items or products not to be used on the furnace.
- The electric furnace filter is a hard working part of the furnace and must be kept clean for the unit to run efficiently. Follow the manufacturer’s instructions for replacing a disposable filter, or the steps when working with a reusable filter.
- Your furnaces air blower also must be kept clean. Use a screwdriver to remove the cover panel. You may also need to remove the fan. Some assemblies slide out, making access easier, it just depends on the model. Clean the blades with the small brush, removing all dirt and debris. With the vacuum hose, remove all the loose dirt. Wipe down the electric furnace unit using a clean soft cloth.
- With another cloth, thoroughly wipe down the motor housing. Do not use soap or water unless specifically approved by the manufacturer as these items can damage the furnace. Keeping this part of the system clean promotes efficient operation and prevents the furnace from overheating.
- Belts and pulleys play a significant role in furnace operation as they work with the motor which produces the heat for your home. Visually check the belts for any issues such as worn areas, cracks, breaks, or tears. Replace if necessary or call a technician to do the job. If they look good, scrub them with a brush, then wipe them down with another soft cloth.
- If the manufacturer instructions allow for the use of water to clean areas such as the blades or belts, allow the furnace to completely dry before plugging in and restoring electricity to the unit.
Electric Furnace Labor Costs
An HVAC installation contractor usually charges $45 to $145 per hour. Since electric furnaces are genuinely easier to install than other furnace types, you may pay less in installation and labor altogether. If you are replacing an old electric furnace, the labor costs will most likely be higher than if you are simply repairing your forced air heating unit. It all depends how many hours in total it takes to complete the furnace installation or replacement and how many skilled contractors are needed to do the job. Make sure to discuss labor costs with your contractor to understand how long the job will take and how much it will cost you.
