When we opened our doors almost 10 years ago, our objectives were clear: carry the finest equipment; offer liberal and straightforward policies; be big enough to provide extensive services and competitive prices but small enough to know our customers. Since 2002, PS Production has made great strides, our industry has been transformed, and we have championed these advances. Through it all, however, the human factor has remained constant. Our customers have not become �digitized� and neither has our way of doing business.

"Work was done in a timely matter. After being installed it worked as it should. The picture on out televisions were much better and great reception . "

"We had lightning rods installed at our home after having 2 previous lightning strikes. The first strike was minor, with only slight damage in the yard. The second was significant when a very large pine tree was hit close to our house causing various electrical issues in the home -- despite having a whole home surge protection system. Just months after having the lightning rods installed, lightning struck an even larger pine tree in our small back yard, Thankfully, the lightning rods saved us! It was a huge strike, and we had no damage at all in the house. These lightning rods were potentially life-saving."

"A great company to work with. After they installed our 24kw generac, they installed a transfer switch in my garage. This allows me to use our 7000 kw generator to operate the well, booster pump and other circuits. Testing went very smoothly and they explained the operation in detail. A great price as well."

Generator Install questions, answered by experts

Natural gas and electricity rates vary significantly based on location, and pricing can change over time, too. It’s possible that in locations where natural gas is particularly inexpensive, it will cost less than grid-based electricity will. However, you should also factor in the generator’s initial costs and maintenance needs, as well as its noise level and if it can comfortably power all your home appliances.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more. 

Yes. You can connect your home back-up battery to a generator with its designated charger. Be sure that the output of the generator matches the input requirements for the battery for best results.

Homeowners can often access federal tax credits, such as the Investment Tax Credit (ITC), which covers a percentage of installation costs. Many states and utilities offer additional rebates, grants, or performance-based incentives. These programs can significantly lower your upfront investment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) or contact your local energy office for current offers.

You can determine what size generator you need by listing the various appliances it will power during an outage. Write down the start-up watt usage, and then add them all together. 

A 7,500-watt generator will run your refrigerator, freezer, well pump, and lighting circuits without a problem. However, you’ll need an extra 3,000 to 4,500 watts to run your water heater and another 5,000 to 25,000 watts to run your electric furnace. In these instances, a whole-home generator is your best bet for running your critical equipment.
