"Very responsive, came out for a quote in a timely manner which I can't say many others did. Has responded quickly to my emails to answer any question I have posed. The crew came on time to position the generator and had it in place as described. As soon as Tim and Robert were notified of gas connection they scheduled final install, showed up exactly on time and completed work in a very professional manner. Very happy with the entire process."

"Chris and Scott were very professional. They only needed two small holes to install the new wires and light. The cleanup in the kitchen was manageable. The price for the job was reasonable. They finished earlier than quoted. I recommended them to my coworker who needed to rewire her thermostat. She was satisfied with the work. I plan to use them again for other home projects."

"Justin did great job, intalled the hookup and the transfer switch for the portable generator. Worked in freezing temperature outside. The only downside was that the install was postponed few times because he was waiting for the parts"

"I had an excellent experience with Stephanie, Tim, and Spencer during the installation of my mini split system. From the very beginning, they were professional, friendly and communicative. They took the time to explain how the installation process would work and made sure I understood all the benefits of swtiching to the system. I felt well informed and supported. Since the installation, the system has made a huge difference in my hosuehold. The units are quiet, efficient, and give me the ability to control the temperature in all rooms in my household. Not only does it keep the space comftorable by replacing AC's but I've noticed the air quality and drop in my electricity bills are better. I"m grateful for the work this team did and would recommend them toothers. I trust them completely and wouldn't hesitate to use them in the future again. Thank you!"

"I called them for a basic service the day after Snomagedon2015 fully expecting not to get anyone out for at least a few days. Someone was at my door within 3hrs! Answers all my silly questions, provided helpful information and advice and cleaned up when he was done. Will definitely be calling them back for future service and installation when the time comes!"

Generator Install questions, answered by experts

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

It is safe to run a generator continuously, but you must follow safety protocols to ensure personal and home safety. Read the manufacturer’s instructions for specific recommendations, but the general recommendation is to turn generators off overnight or when you’re away from the house. Overworked generators can pose a fire hazard and if your generator is not in a well-ventilated area, running it continuously could lead to carbon monoxide poisoning.

Generators are safe to use as long as they are installed and operated correctly according to the manufacturer's recommendations. The most critical safety tips are to never use a portable or fuel-powered generator inside an enclosed space due to the risk of lethal carbon monoxide poisoning; always operate it outdoors where fumes can dissipate away from your home. Additionally, never attempt to connect a generator to your home’s electrical panel yourself—hire a professional to ensure the setup meets safety standards. Finally, avoid overloading the generator by not connecting more appliances than it is rated for, as this can damage your equipment or cause a fire.

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.
