Question 1

How much does a whole house generator cost installed?

Accepted Answer

Whole house generator installation in Washington typically costs $8,000-$15,000 including the generator unit, transfer switch, installation labor, electrical connections, gas line work, concrete pad, and permits. Standby generators (7-22kW) range from $3,000-$6,000 for the unit alone. We provide detailed quotes including all components.

Question 2

What size generator do I need for my home?

Accepted Answer

Most homes need 12-20kW for essential circuits, or 20-26kW for whole-home backup. Size depends on square footage, appliances, heating/cooling systems, and what you want to power during outages. We'll perform a load calculation to determine the right size for your specific needs.

Question 3

How long does generator installation take?

Accepted Answer

Typical residential generator installation takes 1-2 days. This includes: concrete pad installation (if needed), setting the generator, running electrical and gas/propane lines, installing transfer switch, connecting to panel, testing, and final inspection. Complex installations may take 3 days.

Question 4

Do I need a permit to install a generator in Washington?

Accepted Answer

Yes, standby generator installations require both electrical and mechanical permits in Washington. We handle all permit applications, inspections, and ensure compliance with local setback requirements, noise ordinances, and Washington State electrical code.

Question 5

Can a generator run my whole house?

Accepted Answer

Yes, properly sized generators (20-26kW) can power an entire house including HVAC, appliances, lights, and outlets. Smaller generators (7-15kW) can run essential circuits like refrigeration, heating, lights, and critical systems. We'll design a system that fits your needs and budget.

Question 6

How often does a generator need maintenance?

Accepted Answer

Generators should be serviced annually or every 200 hours of use. Maintenance includes oil change, filter replacement, spark plug inspection, battery check, and system testing. We offer maintenance plans with automatic reminders to keep your generator ready for emergencies.

Question 7

What's the difference between standby and portable generators?

Accepted Answer

Standby generators are permanently installed, automatically start during outages, run on natural gas or propane, and power your home through a transfer switch. Portable generators require manual setup, run on gasoline, need extension cords, and must be placed outside. Standby generators offer convenience and safety.

Question 8

How loud is a whole house generator?

Accepted Answer

Modern standby generators operate at 60-70 decibels (similar to normal conversation) from 20 feet away. We ensure placement meets Washington noise ordinances and manufacturer setback requirements (typically 5-10 feet from structures). Sound-dampening enclosures are available for quieter operation.

Question 9

Does a generator increase home value?

Accepted Answer

Yes, whole house generators typically increase home value and make properties more attractive to buyers, especially in areas with frequent power outages. While you may not recoup 100% of installation costs, generators are viewed as valuable home improvements and can be a selling point.

Question 10

What fuel type is best for generators?

Accepted Answer

Natural gas is most convenient if available (no refilling), propane is widely available and stores indefinitely, and diesel is fuel-efficient for large units. Most residential customers choose natural gas for convenience or propane for flexibility. We'll help you choose based on your location and utility availability.
