"I had an outstanding experience with Miguel and highly recommend him for any electrical work! He arrived on time, was incredibly warm, courteous, and professional throughout the entire process. Miguel went above and beyond by securing a permit from the county, installing a transfer switch for my new generator, and even arranging for the inspector to come the same day. The installation was completed quickly, accurately, and at a great price. His attention to detail and commitment to customer satisfaction were exceptional. I will definitely hire Miguel again for any future electrical needs. Five stars!"

"Both installers were very polite and citrus. After installing my unit they explained in fine detail how everything worked. Great workers and completed the work fast. I would recommend Blanton's Heating and Air to all my friends and I hope they get the same workers that installed my system. Great Job."

"These guys were AWESOME. I received 4 quotes Cape Fear came in the lowest with exactly what I wanted, Shane was the salesmen we talked more about the days events then the actual project. When he left he felt like an old friend. He Emailed me my quote and came in $2000,00 less then the other guys with a Trane high efficiency (96% 2 stage furnace and new A/C Unit) the other quotes I got was for a single stage 80% plus ac for more money. The Installer Joe and his crew were great. he took time to answer my questions and ran a new return line from the floor and put it in the ceiling, I definitely got my moneys worth. DO NOT HESITATE TO HIRE THEM!!!!!"

Generator Install questions, answered by experts

A portable generator can supply power to selected appliances and circuits in a home, but it's generally not designed to handle the entire household's electrical needs simultaneously. Portable generators have limited wattage capacity, so they are only designed to power essential devices and electronics temporarily until local power is restored. If your power needs outweigh the capabilities of a portable generator, consider installing a whole-home generator instead.

Generally, you’ll want to keep between 60 and 70 feet between the generator and the transfer switch. There are a few reasons for this, including:

  • The distance reduces the noise coming from the generator into your home.

  • It increases efficiency because you won’t have a voltage drop from this short of a distance.

  • Prevents carbon monoxide poisoning: keep at least 15 feet between your generator and an open window. 

It’s usually better to repair your generator if it isn’t working properly, as it will typically be much more affordable and should yield similar results. Generator repairs cost around $300 on average, while installing a new whole-house generator costs around $5,000 on average. The only exception is if you know your generator is reaching the end of its useful life, usually between 30 and 40 years. If you have an older generator, you could face multiple repairs in the coming years, which might mean that a full replacement will be more cost-effective over time.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

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.
