"He installed the generator and serviced it for $5777.00 and everything was great. We then purchased a new home in January 2017 and he was able to move the generator and reinstall it at our new home for $1,016.00. It went perfectly. They were great people doing a great job because they knew what they were doing. The generator still works and we have had no problems. I would recommend him to everyone."

"Josh in a professional. He made sure that everything was just right before he was done. He bought and installed an electrical transfer switch for me so that when the power goes down, I can just switch over to my generator and power up the whole house. We checked it all out with the generator running and it checked out perfectly. Not only can I connect the generator to the house, but if I decide to get a bigger generator, Iâ m set up to just plug it into the house. I have some other electrical projects that need need to be done and I will definitely call Josh. I recommend Josh for any electrical projects or problems."

"Zach did a great job and completed everything he said he would. The price was comparable to others, with one added plus- no surprises! He charged exactly what he said he would. We are very happy with the results. Holes for butterfly anchors were visible and not filled, hence the 4.5, but this was in a garage and we easily puttied them after he finished. I would definitely recommend Empire Home Solutions and will call them again for future home upgrades."

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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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. 

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.
