Furnaces (Electric Only, No Gas)

These electric-only furnaces-often called air handlers with electric heat-move air for cooling and deliver resistance heat when needed. They are perfect for homes without gas, replacements in existing split systems, and light commercial suites. Models labeled Cool Only with Electric Heat circulate cooling from your outdoor unit and provide electric heat via internal strips.

Choose units that match your system size, including 4-ton configurations (about 48,000 BTU of cooling) with blowers tuned for proper CFM. Refrigerant compatibility matters: these pair with modern R-410A outdoor units and coils. Overall SEER2 efficiency is set by the matched condenser; the electric furnace provides airflow and electric heating.

For DIY-capable homeowners, mounting, duct transitions, and drain setup can be straightforward, while electrical and refrigerant tasks should be completed by a licensed pro. With prices typically $895-$1199, our electric furnace options deliver dependable performance for residences, rental properties, and small offices.

Shop the Electric Blower with Heat Strip subcategory to select the kW heat kit that fits your climate and available amperage, then pair it with a compatible A/C or heat pump.

Frequently Asked Questions

  • Are electric furnaces a good option for homes without natural gas?

    Yes-simple to install, 100% point-of-use efficient; pair with a heat pump to reduce operating costs.

  • What size electric furnace do I need for a 4-ton system?

    Select a 4-ton air handler (about 1600 CFM) with a matching coil and appropriate heat strip kW.

  • Does an electric furnace listed as ‘Cool Only with Electric Heat’ provide heating and cooling?

    It cools when matched to a condenser and heats via electric strips; no gas heat is involved.

  • Is R-410A compatible with my existing outdoor unit?

    Use only with R-410A condensers and coils; never mix refrigerants. Confirm ratings for all components.

  • What breakers or wiring are typically required for an electric furnace with heat strips?

    Depends on kW; common 240V, 30-60A dedicated circuits. Follow the nameplate, NEC, and local codes.

  • Can a DIY homeowner install an electric furnace, or is a licensed contractor required?

    DIY can handle mounting and ducts; electrical, refrigerant, and startup typically require licensed professionals.

  • How do I choose the right heat strip size for my electric blower?

    Base on load and climate: 5-10 kW for mild areas, 15-20 kW for colder zones; verify panel capacity.

  • What is the difference between an electric furnace and an air handler with heat strips?

    They’re essentially the same: a blower/coil assembly with electric resistance heaters for primary or backup heat.

  • Are these units suitable for light commercial spaces?

    Yes, when properly sized and powered; ideal for small offices, retail bays, and similar spaces.

  • What maintenance is required?

    Replace filters, clear drains, check electrical connections, and schedule annual professional inspection and cleaning.
