"Asked the business to install an EV charging outlet and the company install 50 AMPs breaker without doing the correct math for the load. I reached out to the owner thinking that there is an issue with the install as it led to overloading the main breaker which is maintained by the HOA. The owner stopped by and claimed that the installation is correct. The problem is not with the installation as it's with the load and the breaker used. Texted him multiple times, he stopped replying to my text and I haven't heard back from him. HOA hired 3 other licensed electricians to diagnose the main breaker issue and all of them agreed that the load is above 100 with the 50 AMPs installed breaker and reported that back to HOA and now HOA is asking me to fix this and install a breaker with lower AMP. The owner doesn't stand behind his work."

Puget Sound's Home Service Heroes! Offering Plumbing, HVAC, Electrical, Duct & Sewer Services Hunt’s Services is a certified and licensed plumbing, heating, cooling, electrical, duct and sewer services company. We offer same day repairs and emergency services, with over 2,600 five-star reviews by our customers in Tacoma, Federal Way, Auburn, Puyallup, South Hill, Kent, Bellevue, Redmond, Seattle, Olympia and the nearby areas. We take pride in serving King, Pierce and parts of Kitsap and Thurston Counties for both residential and commercial needs with honesty, integrity, and dedicated service.

"had a deeply frustrating experience with Hunt’s HVAC Services that reflects a serious lack of professionalism and customer care. They contacted me early last week to schedule service for my HVAC system, and I agreed to their preferred date—the following Monday. I received a confirmation email on Sunday and a reminder Monday morning for the upcoming afternoon appointment. I drove 1.5 hours to the service site, only to be met with confusion and poor communication. When I called at 12:30 to ask for a specific arrival time, I was told the technician would contact me 30 minutes before arriving—but they couldn’t give me a time estimate. I waited another 2.5 hours before receiving a call informing me that no technician would be coming at all. My only options were to reschedule or cancel. I asked to speak with a manager and was placed on long hold. Eventually, I was told the manager was “too busy” to speak with me and would call me later. That call never came. This experience was a complete waste of time and resources, and the lack of accountability was appalling. Hunt’s HVAC Services failed to honor their commitment, communicate effectively, or show basic courtesy. I strongly advise others to stay away from this business."

I called Eco and they sent Kyle out to diagnose our problem. Kyle was able to quickly isolate the problem to wiring in a recently installed smoke detector. He was able to fix the matter and get us back up and running. I do recommend Eco."

Thank you for choosing a local family-owned business! We provide commercial and residential electrical service from tenant improvements, hot tubs, kitchen remodels, service upgrades, lighting retrofits, new builds, and whatever additions you need. I started my apprenticeship in 2005 and kept working hard to open Bothell Electric in 2021, serving the community I grew up in.

"Andrew and his team replaced all electrical outlets in our house, AFCI/GFCI breakers, installed new exterior fixtures and completed new wiring for our kitchen remodel which included: installing under cabinet lighting, new LeD can lighting, moving our oven and cooktop and installed outlets in our island to bring up to code. Everything was done in a timely manner and was affordable. Bothell Electric is a trustworthy and fair company who treats both customer and employees well. I would hire them again!"

Generator Install questions, answered by experts

Generator size requirements vary wildly among properties, but typical generator sizes are listed below based on home square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14kW

  • 2,500 sq ft: 12–16kW

  • 3,000 sq ft: 16–20kW+

Unfortunately, home square footage isn’t always a good indicator of generator size requirements. Instead, you should call in a professional to discuss which items in your home you’d like to run via your generator. They can calculate peak and average consumption for those items and then size your generator appropriately for optimal performance.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

The typical cost of a home generator is around $5,000, but prices range from $400 up to $13,000, depending on a few factors. The most significant cost factor is the generator size, as larger generators that can support more square footage usually cost more. You can install an emergency backup generator for between $500 and $2,000 or a partial-home generator for between $2,000 and $6,500. Whole-home generators usually total between $5,000 and $13,000, with some models climbing as high as $18,000.

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

In many cases, you’ll need a permit or basic inspection to install one of these large generators. Since they include significant alterations to your home electrical system and many produce exhaust fumes, local governments often require jumping through a few hoops for general safety purposes. Your installer may be able to help you with these permits.
