"Professional, serious, and effective. The exhaust fan/light was installed in our bathroom, with a good ventilation plan to take it out the side of the house. The work was performed well, they cleaned up afterwards very thoroughly, and we're quite happy with the results."

"Bay Line Construction did an outstanding job installing a new electrical outlet and upgrading our panel. The crew was professional, on time, and extremely knowledgeable. They explained everything clearly, worked efficiently, and left the area clean when they were done. The work was done safely, neatly, and passed inspection without any issues. It?s clear they take pride in their craftsmanship and safety standards. I highly recommend Bayline Construction for any electrical work and will absolutely use them again."

"Jim Lockhart is the best of the best. From the time we were planning our project right through completion, he was the model of precision and professionalism. While Jim owns the business, he also worked on site each and every day. Our project together included a 2nd floor master suite addition, additional bathroom remodel, new roof, siding, windows, and HVAC! Jim was always on time and showed up when he said he was. Once our project started he was there every day consistently and worked incredibly hard each day. He worked with high quality sub-contractors when necessary (roof, electrical, and plumbing) and held them to highest standard and was on site while they worked. While construction was occuring, Jim was careful to keep our house as clean as possible and took extra care to ensure my children were comfortable and safe and their home. Jim even took the time say good morning to our dog each day in an effort to make our whole family comfortable! He cleaned each and every day. He was a master communicator and walked us through each step from start to finish. Jim worked on our home for almost 6 months and he took every detail seriously every day. I would highly recommend Jim for any scale job! You would be hard pressed to find a more skilled or professional contractor!"

Generator Install questions, answered by experts

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.

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.

While the rating will tell you how many watts the refrigerator needs at the peak of its cycle, it requires additional wattage to start. At the bare minimum, you’ll need a 1,500-watt generator to get the fridge up and running after a blackout. A 2,000-watt generator should be sufficient for most home refrigerators.

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.

Most homeowners won't be able to claim a home generator as a tax write-off. However, a whole-house generator may be tax-deductible in certain situations depending on its purpose. For instance, if it's needed to power essential medical equipment, it may qualify as a medical expense deduction. Also, in some cases, businesses can deduct a generator as a business expense if it supports operations. Always consult a tax professional to determine eligibility based on your specific circumstances and the applicable IRS regulations.
