"We are part way through the process of installation of a Backup home generator. Rob provided excellent information at the first visit. He discussed various options for our home, and the process made me very confident about the decisions we made."

"If I could give Jeremy and his team 10 stars I would, they are simply that good! He has installed recess lighting in both of the houses we have owned. Both houses we have owned have a light switch connected to an outlet. He installed new lighting and made sure that the wiring to the outlet works without a switch. He did this for both our living room and upstairs master bedroom. We also asked him if he would install a generator plug outside as well. He installed it and made sure we knew A.) how to run the generator. B.) How to turn the panel off and switch the main breaker on for the generator and C.) Made sure he labeled all breaker switches we were able to use while using the generator to power the house. I will never use anyone but Jeremy and JMP Electric moving forward on any electrical for my house. I would highly recommend him and his company. He is just simply amazing. Look no further when looking to have someone do your electrical. You really won't find anyone better."

"I called Cawiamca furnace service from home advisor. From the time they discovered the problem my furnace was leaking CO2 into my house only to discover many cracks inside the furnace and SAFETY Was first priority. The next day the furnace was delivered and installed and old one taken away. Of course I had a hardship and this company worked with me. The guys were very polite clean and very neat. This is my first time with this company I will have them for all my furnace needs. They were all very prompt in showing up on the job and eager to start work. GREAT COMPANY AND HIGHLY RECOMMENDED!!!!"

"The electrician Kyle was professional , honest and affordable. He was punctual and courteous. I hired him for the wiring and panel upgrade but I requested he change my six GFCI outlets and check the older outlets. He checked the outlets that I was worried about -they were good. He did need to replace a different inside outlet and 2 of the 4 outside outlets. He was kind and explained why they needed to be replaced. One just was no longer working. The other 2 were not up to code actually were a fire hazard. I am female senior citizen grateful I hired Elevate Electric."

Generator Install questions, answered by experts

The cost to install a whole-house generator averages $5,200, with a typical price range of $1,500 to $8,900. However, total costs can vary from $400 for a small portable unit to over $18,000 for a large-capacity system. The most significant cost factor is the generator's size and capacity, but other variables include the brand, fuel type, and labor for assembly and installation.

Generator costs can be broken down by type:

  • Portable or Emergency Backup Generators (1kW–7.5kW): $500 to $2,000

  • Partial-Home Generators (9kW–20kW): $2,000 to $6,500

  • Whole-House Generators (22kW–48kW): $5,000 to $18,000

To avoid paying for more power than you need, consider hiring an electrician to calculate the electrical load for your essential appliances. It is also recommended to get at least three quotes to find the best deal for your specific needs and budget.

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. 

If you’re wondering whether gas generators produce carbon monoxide, know that natural gas generators do not produce carbon monoxide if they are functioning properly, as natural gas burns cleanly. However, if the generator malfunctions and the gas does not burn completely, there is potential for carbon dioxide to be produced. To prevent malfunctions, it's crucial to perform regular maintenance, including running the generator weekly and scheduling professional inspections every 6 to 12 months. Also, be sure to test your carbon monoxide detectors regularly to ensure they function in the rare case of the generator producing carbon monoxide.

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.

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.
