"I have been hiring Cody Malone since we purchased our house in July 2012. They have switched out outlets, installed indoor ceiling fans, installed outdoor ceiling fans, ran electrical to my outdoor water feature and switched out my light fixtures. I plan to hire them again when I add electric to my detached garage. They always do a great job and arrive when they say they will. I have never had a single issue and they have been to my house for no less than six different projects!"

"I was very impressed with this company from beginning to end. When they gave me an estimate, they spent 90 minutes with me to make sure I selected the right furnace and AC. The crew came two days later and installed the furnace and AC in one day. Great job! Very happy with the whole experience. I highly recommend this company to others."

Generator Install FAQs, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

Costs range from $500 to $2,500, depending on generator type and installation complexity.

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.

Yes, installing a generator usually increases your property value because buyers are getting the added peace of mind knowing they’ll be able to maintain power through blackouts. In most cases, you should see close to a 100% return on investment (ROI). Keep in mind that home generators usually need a permanent foundation, and installing a concrete slab will likely raise your property taxes slightly.

These advanced generators use a key fob or a smartphone app to remotely start, which is ideal for getting power back on immediately without venturing outside. This feature is more common on whole home generators, but you may be able to find it on large portable generators, too.
