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."

"David was very no-nonsense, quickly assessed the problem and resolved it for a reasonable service call fee in about 20 minutes. He was thorough and professional, and Juice Company will be the first ones we call when were ready to do additional work. This was in contrast to another company who spent two hours giving us a hard sell on a complete overhaul of our home's electrical system but never got around to fixing our immediate issue."

Generator Install questions, answered by experts

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

A whole house generator can be worth the extra money for peace of mind if your home is prone to power outages for extended periods of time or if you have life-saving medical equipment that needs to maintain power at all times. These devices can also increase your home’s value, especially in areas prone to extreme weather and power outages.

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.

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.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.
