  1. Natural gas generators cost $2,000 to $6,000 for a whole house, depending on size. They can be installed to a home’s existing gas line and require no fuel storage. Natural gas is cheaper than diesel or propane, but relies on pipelines that may be shut off or damaged during severe storms. Liquid propane generators cost $250 to $4,000 for portable models or $2,000 to $6,000 for permanent backup units, depending on size.
  2. Liquid propane lasts longer and burns cleaner than other fuels but is more expensive and requires a large storage tank, which increases installation costs. Portable diesel generators cost $3,300 to $6,700 and whole-house diesel generators cost $5,000 to $18,000.
  3. Diesel generators are more efficient, reliable, and require less upkeep than natural gas or propane generators.
  4. However, they cost more, require manual refueling, and emit pollutants. Portable solar generators cost $500 to $3,300 and are ideal for apartment and condo residents or homeowners seeking an environmentally friendly solution.
  5. Solar generators run quietly, produce no fumes, and can be used indoors, but can’t store enough energy to power a whole home. Generac generators cost $2,000 to $5,000 for a 7 to 24 kW whole-house unit, plus $3,000 to $5,000 for installation. Generac’s standby generators turn on automatically during power outages and run on natural gas or liquid propane.
  6. Generac is the leading brand in whole-home generators. Other standby generator brands to compare are Kohler, Briggs & Stratton, Honda, and Cummins. A Kohler generator costs $2,700 to $16,000 depending on size, ranging from 6 to 48 kW. Kohler home generators run on natural gas or liquid propane, feature remote smartphone monitoring, and include an automatic transfer switch to turn on automatically during power outages.

Briggs & Stratton home generators cost $2,400 to $15,300 depending on size, with models ranging from 10 to 48 kW. Briggs & Stratton generators feature wireless monitoring, automatic low oil shutdown, and power management to control power distribution to select appliances and prevent overloads.

Cummins standby generators cost $3,100 to $13,900 for models ranging from 13 to 40 kW. Cummins generators feature sound-insulated enclosures, remote diagnostics, and intelligent load management to balance power use across multiple appliances so a smaller generator can power an entire home.

Home generator installation costs $3,000 to $5,000 on average, not including the backup generator itself. The cost to install a whole house generator depends on the size, fuel source, distance from the electrical panel and gas meter, and amount of wiring and gas plumbing to hook up.

Complex generator installation jobs may require long trenches for electrical conduit and gas pipes, propane tank installation, or higher labor costs to install liquid-cooled generators.

Installing Cost For a Generac Home Generator

Electricians charge$40 to $100 per hour to install wiring and hook up a backup generator to the electrical panel. Natural gas and liquid propane generator installations require gas plumbing by a licensed professional. Gas line installation costs$12 to $25 per linear foot.

Installing a liquid propane generator typically costs more than a natural gas or diesel generator because it requires a new fuel tank. Propane tanks cost$400 to $1,800 on average. Separate electrical, plumbing, and mechanical permits may be required depending on local regulations.

Generac Generator Costs

Permits cost $80 to $450 total on average. A pre-cast concrete pad costs$150 to $400 for a generator, which is typically three to four inches thick. The average cost to install a generator transfer switch is $400 to $2,000 for materials and labor. For labor alone, and electrician costs $200 to $500 and takes three to four hours to install a transfer switch.

A manual or automatic transfer switch connects a generator to a home's electrical panel. Manual transfer switches are ideal for portable generators, but the switch must be flipped manually when the power goes out. Automatic transfer switches are optimal for standby generators and automatically turn on a generator during a power outage. A manual transfer switch costs $200 to $800 on average, and an automatic switch costs $400 to $2,000.

Generator Installation Costs

Prices depend on the amperage and don't include installation. The transfer switch amps must match the main breaker in the electrical panel. Otherwise, transfer switches that only power select circuits should be sized by an electrician according to the power requirements. A generator interlock installation costs $400 to $850 on average for the interlock kit, power box, breaker, cords, and electricians labor.

An interlock kit allows a portable generator to connect to the electrical panel without a transfer switch and eliminates a dangerous direct connection.

An interlock covers the panel's main cutoff switch so it can't switch on while the backup generator is running.

Home Generator Cost Factors

Not all interlocks meet local building codes or work with every electrical system. For safety, a generator should be located outside at least five feet away from doors, windows, vents, and flammable material.

We Install Any Generator Brand or Model

Most generators produce 60 to 70 decibels (dB) from 25 feet away, similar to a central air conditioner. Some city properties are tighter, increasing the noise level, which may be regulated by local noise ordinances. Generators need regular maintenance to ensure reliability.
