What Federal Way Homeowners Say About Our Electrical Services Work

Larry B.
★★★★★
Your technician installer Aaron showed great patience as we went through the process of setting up a wi-fi extender to complete setup of the Generac app. Save time when you prepare for a generator install and just set up a wi-fi extender ahead of time with a 2.4 Ghz connection to get wi fi outside to the generator - this tracks usage. Aaron has great customer service and communication skills and walked us through the process. The City permit inspector said that our install was great! So happy that we went with Northwest Heating - we are customers for life and highly recommend them!

Northwest Expert Heating, Cooling, and Electrical offered a very fair price for a good product. The employee who came out to give me an estimate, Christopher, was very friendly and professional. The install was quick and mostly seamless.

How Northwest Expert Approaches Generator Installs in Federal Way

Plenty of companies can drop a generator on a pad. We treat your install as a full home electrical project, because that is exactly what it is. Since we are a heating, cooling, and electrical company under one roof, our techs look at how your furnace, heat pump, water heater, and panel all draw power before recommending a unit size. That means you never overpay for capacity you will not use, and you never end up with a generator that struggles when everything kicks on at once. We also coordinate permits and inspections, so your Federal Way, WA generator install is done right the first time.

Stay Powered Through Every Federal Way Outage

A whole home generator is a real investment, and we respect that. You get a clear written quote before any work begins, with no surprise charges once the job is underway. Your install is backed by our service guarantees, and our team walks you through how the system runs, how the automatic transfer switch works, and what simple maintenance keeps it ready for the next storm. Homeowners across Federal Way, WA tell us the first outage after install is when it really clicks: the power drops, the generator starts, and life carries on like nothing happened.

Frequently Asked Questions

What size whole home generator do I need?

It depends on what you want to keep running during an outage. A home with electric heat, a well pump, or a heat pump needs more capacity than one running only essentials. We perform a load calculation on your Federal Way, WA home so the generator we recommend handles your real demand without oversizing.

Most installs are completed in one to two days on site. Permit approval and utility coordination can add some time before work begins, and we handle that scheduling for you so the process stays simple.

Standby generators typically run on natural gas or propane. If your home already has natural gas service, we can usually connect to it directly. If not, a propane tank is a reliable option, and we will walk you through both before you decide.

Yes. A whole home generator install requires permits and an inspection to make sure the electrical and fuel connections meet code. Our team coordinates the permitting process so your installation is fully compliant.
