However, I also need to be honest about the downsides. Some users reported quality control issues, including motor mounts arriving broken and transformer problems right out of the box. These are real concerns worth weighing. The 3.5-star average reflects a split experience: about half the users love it, while others experienced frustrating problems.
What Does the Vent-Free Design Mean for Installation?
Vent-free means the furnace does not require an exhaust vent or flue to the outside. Since electric furnaces do not produce combustion gases, there is no carbon monoxide risk and no need for venting. This simplifies installation because you can place the unit in nearly any room without worrying about running exhaust pipes through walls or roofs.
The freestanding mounting type means you can position this furnace on a level surface without building a dedicated enclosure. That flexibility works well for workshops, garages, or utility rooms where a permanent built-in installation is not practical.
Should You Trust the Mixed Reviews?
The 3.5-star average tells you this is not a perfect product, but it is also not universally disliked. Half the reviewers gave it 5 stars, praising its heating performance and value. The negative reviews primarily focus on shipping damage and quality control issues rather than heating failures.
If you choose this unit, I recommend inspecting it carefully upon delivery and testing all components before installation. The customer service team appears responsive based on user feedback, so any issues should be addressable. For the price-conscious buyer willing to handle potential hiccups, this Garrison model offers solid heating capacity at a lower cost than premium brands.

What Does A/C Ready Actually Mean for This Furnace?
A/C ready means the furnace is designed to integrate with an air conditioning system without requiring major modifications or additional components. The factory-installed coil cabinet can accommodate air conditioning systems ranging from 2 to 5 tons. When you add an outdoor AC unit, the refrigerant lines connect to the coil cabinet inside the furnace.
This integration means one system handles both your heating and cooling needs. The 16 programmable blower speeds work for both heating and air conditioning modes, giving you comfort control across all seasons. Without an A/C ready furnace, you would need to install a separate air handler or make modifications to accept an evaporator coil.
Why Does R-454B Compatibility Matter?
R-454B is a next-generation refrigerant that replaces older refrigerants with high global warming potential. As environmental regulations phase out older refrigerants, new air conditioning systems increasingly use R-454B. Having a furnace that is compatible with this refrigerant means you can install a modern, compliant AC system without compatibility issues.
If you plan to add air conditioning now or in the near future, R-454B compatibility future-proofs your investment. Older furnaces designed for R-410A or R-22 refrigerants may not work with newer AC systems, potentially requiring costly modifications or complete system replacements.

The E7EU-B020K1 (upflow) and E7ED-B020K1 (downflow) share the same 63,000 BTU heating capacity and 20kW power rating. The key difference is airflow direction. The upflow model draws cool air from the bottom and pushes warm air upward, while the downflow model does the opposite.
Your choice depends entirely on your home’s ductwork configuration. Upflow furnaces work best when installed in basements or lower levels. Downflow furnaces are better for attic installations or closet placements above the living space. Both deliver the same heating performance once installed correctly.
Is 150 Pounds a Concern for Installation?
At 150 pounds, this is the heaviest furnace in our review. Professional installation with two technicians is recommended for safe handling. The weight comes from the substantial heating elements, insulated cabinet, and built-in coil cabinet. While the weight makes handling more difficult, it also indicates robust construction with quality components.
Your installer will need to ensure the floor or platform supporting the furnace can handle this weight. In most mobile home installations, the existing furnace pad or platform is designed to support this load. If this is a new installation, your contractor will verify structural support before placement.
Buying Guide: How to Choose the Best Electric Furnace for Your Home
Choosing the right electric furnace comes down to matching the heating capacity, airflow configuration, and electrical requirements to your specific home. I want to walk you through the key factors so you can make an informed decision rather than guessing.
Understanding BTU and kW Ratings
BTU (British Thermal Unit) measures heat output, while kW (kilowatt) measures electrical power consumption. For electric furnaces, the relationship is straightforward: 1 kW equals approximately 3,412 BTU per hour. A 10kW furnace produces about 34,120 BTU, while a 23kW unit delivers around 78,476 BTU of heating capacity.
When comparing furnaces, focus on BTU output for sizing purposes. The kW rating helps you estimate operating costs based on your local electricity rate. A 15kW furnace running at full capacity for one hour consumes 15 kilowatt-hours of electricity. Multiply that by your local rate to estimate hourly operating costs.
Sizing Your Electric Furnace by Square Footage
Proper sizing is the single most important factor in furnace selection. An undersized furnace will run constantly without reaching your desired temperature, while an oversized unit will short-cycle and waste energy. Here is a general sizing guide for electric furnaces:
For mobile homes, a 10kW (31,000 to 34,000 BTU) furnace suits homes up to 1,000 square feet in moderate climates. A 15kW (47,000 to 51,000 BTU) unit works for 1,000 to 1,500 square feet. For larger mobile homes up to 2,000 square feet, a 20kW (60,000 to 68,000 BTU) furnace provides adequate heating. The 23kW models handle the largest mobile homes or those in very cold climates.
For standard residential homes, sizing depends heavily on insulation quality, ceiling height, window efficiency, and climate zone. Always consult with a licensed HVAC contractor who can perform a Manual J load calculation for accurate sizing specific to your home.
Upflow vs Downflow vs Horizontal Configuration
The airflow direction of your furnace must match your ductwork layout. Upflow furnaces draw cool return air from the bottom and discharge warm supply air from the top. They work best when installed in basements, crawl spaces, or ground-level utility rooms below the living space.
Downflow furnaces do the opposite, drawing air from the top and discharging warm air from the bottom. These are ideal for attic installations or closet placements where the ductwork runs below the unit. Horizontal furnaces are designed for tight spaces like crawl spaces or attics where vertical clearance is limited.
If you are replacing an existing furnace, match the configuration of your old unit unless you plan to rework your ductwork. The Goodman MBVB20DP1X00 in our review is the only multi-position model, capable of adapting to any configuration.
Mobile Home vs Standard Home Furnaces
Mobile home furnaces are specifically engineered for manufactured housing. They meet HUD (Housing and Urban Development) code requirements and are designed for the unique construction characteristics of mobile homes, including thinner walls, different ductwork configurations, and specific clearance requirements.
Most of the Revolv furnaces in our review carry mobile home certification. If you live in a manufactured home, always choose a furnace specifically rated for mobile home use. Standard residential furnaces may not meet code requirements and could create safety issues in manufactured housing installations.
The Goodman modular blower and the Garrison furnace in our lineup are more suited to standard residential or mixed-use applications. The Garrison unit works well for workshops, cabins, and smaller spaces that need dedicated electric heating.
Electric Furnace vs Heat Pump: Which Is Better?
This is one of the most common questions our team encounters. Electric furnaces and heat pumps both run on electricity, but they work differently. An electric furnace uses resistance coils to generate heat, achieving 100% efficiency at converting electricity to heat. A heat pump moves heat from outside air into your home, achieving 200% to 400% efficiency because it transfers rather than creates heat.
Forum users on Reddit consistently recommend heat pumps over electric furnaces for their dramatically lower operating costs. One user reported paying $250 per month to run an electric furnace including a well pump, while heat pump users in similar climates reported bills 3 to 4 times lower. However, heat pumps lose efficiency in very cold temperatures and may need backup heat.
Electric furnaces win on simplicity, reliability, and upfront cost. They have fewer moving parts, no outdoor compressor unit, and no refrigerant to maintain. For homes in moderate climates or as backup heating for a heat pump, an electric furnace remains a practical choice.
Installation and Electrical Requirements
Electric furnaces require significant electrical service. A 10kW furnace needs roughly 42 amps at 240V, while a 20kW unit requires approximately 83 amps, and a 23kW model needs around 96 amps. Your electrical panel must have enough capacity to handle this load along with your other household electrical needs.
Professional installation is strongly recommended. A licensed electrician and HVAC contractor will verify your panel capacity, install the correct wiring and breakers, connect the ductwork, and test the system for proper operation. Improper installation can create fire hazards and void your warranty.
Most electric furnaces in our review include 10-year manufacturer warranties when registered. Some models, like the Revolv E7ED-B020K1, include 5-year parts warranties. Always register your product after installation to activate full warranty coverage.
Operating Costs to Expect
Electric furnace operating costs depend on your local electricity rate, the furnace kW rating, and how many hours per day it runs. In areas with electricity rates around $0.15 per kWh, a 15kW furnace running 8 hours per day costs approximately $18 per day or $540 per month during peak winter months.
Our team found that forum users report widely varying costs depending on home insulation, climate, and usage patterns. Improving your home’s insulation, using a programmable thermostat, and maintaining your furnace regularly all help reduce operating costs. The ECM blower motors found on some models in our review also contribute to lower electricity consumption.
FAQs
What is the $5000 rule for furnace?
The $5000 rule is a simple guideline for deciding whether to repair or replace a furnace. Multiply the age of your furnace (in years) by the estimated repair cost. If the result exceeds $5000, you should replace the furnace rather than repair it. For example, a 12-year-old furnace needing a $450 repair would give you $5400, meaning replacement is the better financial decision.
What is the average cost of a new electric furnace?
A new electric furnace typically costs between $1,000 and $2,700 for the unit itself, with most quality models falling in the $1,400 to $1,800 range. Professional installation adds $1,500 to $3,000 depending on electrical work needed, ductwork modifications, and your location. Total installed cost generally runs $2,500 to $5,000 for a standard mobile home or residential installation.
What brand of furnace is the most reliable?
Goodman is widely regarded as one of the most reliable electric furnace brands, praised by HVAC professionals and forum users for build quality and repairability. Revolv (manufactured by Nordyne) is the leading brand for mobile home and manufactured housing applications. Carrier is recognized as a premium option known for quiet operation and smart thermostat integration.
Is an electric furnace a good idea?
An electric furnace is a good idea if you live in an area without natural gas access, want clean heating without combustion byproducts, or need a lower upfront cost compared to gas furnace installation. Electric furnaces achieve 100% energy efficiency and have fewer moving parts than gas models. However, they cost more to operate monthly than gas furnaces or heat pumps, so consider your local electricity rates before deciding.
How long do electric furnaces typically last?
Electric furnaces typically last 20 to 30 years, which is longer than gas furnaces that average 15 to 20 years. The extended lifespan comes from having fewer moving parts and no combustion process that creates wear and heat stress. Regular maintenance, including annual inspections, filter changes, and keeping the heating elements clean, helps maximize the lifespan of your electric furnace.
What size electric furnace do I need for a 2000 sq ft house?
For a 2,000 square foot home, you typically need an electric furnace rated between 20kW and 23kW, producing approximately 68,000 to 78,000 BTU of heating output. The exact size depends on your climate zone, insulation quality, ceiling height, and number of windows. Always have a licensed HVAC contractor perform a Manual J load calculation for precise sizing specific to your home.
