"Highly recommend contacting them for electrical work! Responded quickly to come and give a quote for a generator hook up. Explained everything thoroughly and gave helpful suggestions as this was my first experience getting a generator to power the house. Very reasonable pricing. From first contact to getting it installed in under 2 weeks. Very happy!!"

"Tylor was quick to respond to my inquiry and very accommodating to fix my problem as soon as he could. His expertise was shown as he diagnosed the possible issue over the phone and he had it fixed in no time once he arrived. He even fixed a lesser issue for no extra charge. I found his rates exceptional, and he will always be my first call for any of my future electrical issues."

"I highly recommend him for any electrical work! He has completed several projects at my home and has done a phenomenal job every time. He installed recessed lighting in three bedrooms and my bathrooms, as well as completed an outdoor project that required running new electrical wiring. His work is always professional, clean, and done right. He is extremely reliable, responsive, always shows up on time, and is willing to travel wherever the job is. His pricing is also very reasonable and economical for the quality of work he provides. On top of being a great electrician, he is a genuinely great person to work with. I will definitely continue using him for future projects and highly recommend him!"

"Highly recommend!! Peter was very professional and easy to work with. Came when he said he would and finished the job on time. He also returned after the installation was complete to make certain furnace was running well and to install a new CO2 monitor when he noticed mine was outdated."

"I had a small electrical fire on a Saturday from out dated cloth wire. These guys showed up got it fixed to where my house was safe and came back on a Sunday to get it 100 percent done rewiring my out door lights for my front door. Amazing professional work. They came back a little later and re wiring my entire house for me new panel new wires handled the permit. I can’t say enough about their work and professionalism I have no issue leaving them a key to work while I’m not home. Again amazing quality work"

Generator Install questions, answered by experts

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 diesel is relatively stable, it won’t last nearly as long as propane and you may have to replace it if it sits unused for too long. Diesel can sometimes struggle to work efficiently or start engines during especially cold weather, so it’s not the best choice for every climate. Compared to fuels like propane and natural gas, diesel generators tend to be noisier and create more exhaust, which isn’t always ideal for home use.

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.

Whole-house generators need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.

In some situations, yes. Never try to put biofuel into any home generator without checking the specifics first. If a generator has the ability to run on diesel, it can also run pure biofuel (the clear kind made from seed oils, for example). But if you are using biofuel made from animal fats or vegetable oils, the generator will need significant modifications before it can handle a sludgier type of biofuel.
