"John was very accommodating and understood exactly what we needed. He was prompt, courteous, and kept me informed throughout the process, as the work was done for my mother while I wasn't there. My mom was very pleased with her ceiling fan light fixture installation and the price was very reasonable. I would definitely call him again for any other job I need done. Thanks again John!"

"After putting in a request on Home Advisor, Mike responded very quickly. I advised him i wanted to install a transfer switch for a generator and he went through the steps of what would need to be done. He asked a few questions, asked for a picture of the junction box, and then gave me a very reasonable quote. The day of the install, he called to reconfirm our appointment. The install was quick and clean."

"The electrician clearly explained what he was doing and why. He did not do anything additional until he had my approval. He also pointed out a rigged outlet fixture for a generator and identified it as dangerous and asked if he could remove it. We have more work to be done and we will have them back."

"I am very happy that I hired Patience HVAC to replace my hot water heater. I have an oil burner and oil hot water heater. The 18 year old heater was making crackling noises and I was advised by the oil company to replace it. I wanted to convert to a gas hot water heater and tried going through Lowes. However, they only do swap outs if the existing heater is already set up for gas. So I contacted several companies for a quote. Out of all of them, Anthony was the most professional, down to earth and reasonably priced. First, he suggested to explore correcting the issue on the old heater and save me money which was impressive. I decided to proceed with a new gas heater. The quote he gave me was $800 less than the next lowest quote. Anthony sent his workers Caesar and Matt the next day which I greatly appreciated. They were both very polite and wore covers on their shoes so to avoid dirtying my house more than necessary. Anthony came later in the day to ensure everything was done correctly. He then offered to call him with any questions even if they were not pertinent to the work they performed. I am extremely impressed with patience HVAC honesty, professionalism and reasonable prices. I will be sure to recommend them to friends and family. When I am ready to install a ductless air conditioner, I will definitely contact Patience HVAC."

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

If you’re deciding between a solar battery versus a generator for the best backup power solution, you can take a few factors into consideration. Solar batteries are quiet while generators can be quite loud. Generators have a lower up-front cost, but they require fuel and ongoing maintenance while solar batteries are more expensive but don’t have many ongoing costs.

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.

Whole-house generators can run continuously for extended periods, even for weeks at a time (around 400 to 500 hours), as long as they have a sufficient fuel supply. However, this type of extensive use will increase wear and tear and can shorten the generator's overall lifespan. During long periods of operation, it's important to check and refill the engine oil as needed, potentially as frequently as daily depending on the model. If your generator uses a fuel tank, ensure it is kept full to prevent unexpected shutdowns.

An undersized whole-house generator has the potential to overheat and shut down when you try to run a central AC system. This scenario can not only damage the whole-house generator, but can also trip your home’s breakers or cause electrical damage. To avoid this situation, hire a local generator installer to correctly size your whole-house generator.
