"I just wanted to say that this was my first experience with a trades company in my home and I had no idea what to expect. I was blown away at the professionalism and attention to detail from Arron and Matt. They showed me how much I was overpaying by having a tank water heater and they were able to remove the tank and install a tankless SAME DAY!! I will never use another company other than Eco."

"We had As You Wish come out and quote a panel upgrade for a new generator setup with direct plug. All Generac equipment. They took a small deposit and came back a few days later and did the work. Drivers came from Tacoma area and were on time. Techs were Alejandro and I didn't catch the other guys name. Super nice and knowledgeable. They got everything staged, boxes mounted to the walls and ready to go before turning off the power to hook it all up. Once they had the power off, they worked quickly and got it done and the power was back on. Once it was done, they cleaned up and showed me how to use the system when I need it for the next power outage. When it came time to pay the balance, it was exactly what was quoted and not a penny more. Its was a refreshing experience to have both great techs and no surprises for the payments. I will absolutely have them do any other work I need on this property without hesitation. Total invoice was $5,323"

"Starting with the sales process, Nate was informative and great. Could've sold me a more expensive replacement system, but instead identifies how my current system cod be retrofitted with a heat pump. That sold me on G&S right there. Everything from the initial install review, the office staff working with my lender, to Izaak and the install and electrical teams, was punctual, informative and professional. I've had several bad experiences with other contractors, but I would confidently recommend G&S for any job and plan to use them again for a generator switch install. Good people with a good business. Thank you G&S!"

Generator Install questions, answered by experts

Yes, natural gas generators can work without electricity. Natural gas generators are a common type of backup or whole-house generator that operates when the electrical grid isn’t working. The trick is using a transfer switch (which usually needs to be installed with the generator) that safely switches the home electrical system from the power grid to generator power when needed.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Carbon monoxide emissions aren’t only dangerous to human life, but they also harm our planet. While natural gas generators emit lower levels of CO than other fuel sources, there are still ways to reduce emission levels. For example, shop around for an eco-friendly generator that complies with current emission standards. Also, make sure your generator is serviced regularly to avoid CO buildup. 

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

Many services include assembling the unit and securing it in the window. Confirm with your provider.
