can be powered by standard gasoline, diesel, or LP gas. If you experienced regularly or if heating and cooling systems solely rely on electrical power, investing in a whole house generator would be a smart idea.

How Much Does it Cost to Install a Whole House Generator?
Now that we know how much the average cost is for the generator, its time to factor in the cost for installation.
Generators are commonly placed on a cement pad somewhere outside the property. They are permanently secured and require gas hookups and electrical wiring.
In some cases, depending on where you live, you need to have special permits or permission from the city to install a permanent generator to your property. Always have a trusted professional
install your generator.
Trying to do it yourself may grant you a fine from the city and is also extremely dangerous if you have no prior knowledge of installing one.
A good rule of thumb to follow is by taking 75% of the purchase price of your generator is what you should expect for your installation. For example, if you bought your generator for $2,000, expect to pay around $1,500 to get it installed.
The price should cover the cost for site preparation
- Cement pad construction
- Generator transfer switch installation cost
- permits and permissions
- materials and equipment
Installation costs will vary depending on the situation. If you purchase a generator that runs on LP gas, you will need to pay extra for lines to be bury lines that go from your generator to the LP gas tank.
What other Considerations should I Keep in Mind Before I Purchase a Generator?
Have a budget in place and a plan of action. Having a standby generator is a smart idea and will provide the necessary power you need in case you experience a power outage. But, make sure you know how much you can afford and what your power needs are.
Another consideration you need to be aware of is that the generator can make a substantial amount of noise—up to 100db.
Make sure you check with your city if you need a permit to run a generator, especially in tightly crowded neighborhoods. You can also pay to have it soundproofed to avoid complaints.
If you don't have many power outages in your area and just need a few things on if the power does go out, go with a smaller generator in the 7 to 14kW range.
If you have more in your budget or need a generator to run central air, heat, sump pump, CPAP machine, or other medical devices, go with one that is in the range of 14 to 48kW range.
