Understanding Electric Furnaces

Electric furnaces are heating systems that use electric resistance heating elements to warm air, which is then distributed throughout a home via ductwork. Also called modular blowers or electric air handlers, they achieve 100% AFUE efficiency because all electricity converts directly to heat without combustion losses.

Electric furnaces work by pulling cold return air through heating elements called heat strips, which are powered by electricity. A blower fan forces the heated air through ductwork and into living spaces. Modern units use ECM motors for variable speed control and multi-stage heating elements for precise temperature management.

The main advantages include no carbon monoxide risk, no venting requirements, cleaner operation, and 100% energy conversion efficiency. Electric furnaces also serve as excellent emergency backup for heat pump systems when temperatures drop below the heat pump’s effective operating range.

Electric Furnace Buying Guide

Choosing the right electric furnace requires careful consideration of several critical factors beyond just price. The following guide covers sizing, efficiency features, electrical requirements, and installation considerations to ensure you select a system that matches your specific needs.

Sizing Your Electric Furnace: BTU Requirements

Proper sizing is critical for electric furnace performance and efficiency. Undersized units struggle to maintain temperature on cold days, while oversized units cycle frequently causing comfort issues and potential humidity problems.

Square Footage	Warm Climate (30 BTU/sq ft)	Moderate Climate (35 BTU/sq ft)	Cold Climate (40 BTU/sq ft)
800 sq ft	24,000 BTU (7 kW)	28,000 BTU (8.2 kW)	32,000 BTU (9.4 kW)
1,000 sq ft	30,000 BTU (8.8 kW)	35,000 BTU (10.3 kW)	40,000 BTU (11.7 kW)
1,200 sq ft	36,000 BTU (10.6 kW)	42,000 BTU (12.3 kW)	48,000 BTU (14.1 kW)
1,500 sq ft	45,000 BTU (13.2 kW)	52,500 BTU (15.4 kW)	60,000 BTU (17.6 kW)
2,000 sq ft	60,000 BTU (17.6 kW)	70,000 BTU (20.5 kW)	80,000 BTU (23.5 kW)

For a 2,000 sq ft home, you typically need 60,000 to 80,000 BTU electric furnace depending on your climate zone. Warmer southern regions need around 60,000 BTU (30 BTU per sq ft), while colder northern regions require 80,000 BTU or more (40 BTU per sq ft). Always get a professional Manual J load calculation for accuracy.

Efficiency Features: ECM Motors and Variable Speed

The most significant efficiency advancement in electric furnaces is the ECM (Electronically Commutated Motor) blower motor. ECM motors reduce energy consumption by 20-60% compared to standard PSC motors while providing more consistent airflow, better humidity control, and quieter operation.

Variable-speed and multi-stage heating elements allow the furnace to match output to demand precisely. Instead of full-power cycling, these systems modulate to maintain temperature more efficiently, reducing energy waste and improving comfort.

Electrical Requirements: Panel Capacity and Wiring

Electric furnaces require substantial electrical power. A 20 kW unit like the Garrison B00MLP4PNU requires 200 amp electrical service with two 50 amp breakers. Smaller 5 kW units need approximately 25 amp circuits, while 10 kW units typically require 50 amp breakers.

Before purchasing, verify your electrical panel has sufficient capacity. Older homes with 100 amp panels may require expensive upgrades to accommodate larger electric furnaces. The 208/230V single-phase power requirement is standard for residential units.

I recommend having a licensed electrician assess your panel capacity and wiring before making your purchase. Inadequate electrical service is a common reason for returns and can add significant unexpected costs to your installation.

Installation Considerations: Professional vs. DIY

All major manufacturers require professional installation for warranty coverage. This isn’t just upselling—proper installation ensures safety, efficiency, and warranty protection. Professional HVAC technicians have the tools and knowledge to handle refrigerant lines (if paired with cooling), electrical connections, and airflow balancing.

For manufactured homes, look for units specifically approved for mobile home installation. These models are designed for the specific static pressure requirements and space constraints of manufactured housing. Standard electric furnaces may not be approved or safe for mobile home applications.

Warranty Coverage and Brand Reliability

Goodman offers 10-year parts limited warranty on their electric furnaces when installed by qualified professionals and registered within 60 days. King Electric provides similar coverage on their garage heaters. Always read the fine print—some brands exclude certain components from warranty coverage or have shorter terms for specific parts.

Brand reputation matters for parts availability and service network coverage. Goodman, backed by Daikin, has extensive distribution networks ensuring parts availability for years. King Electric’s made-in-USA manufacturing supports long-term availability. Lesser-known brands may leave you stranded when replacement parts are needed.
