"He was patient and knowledgeable. He even cleaned up a little after the job and took away the old ceiling fan to recycle it for me. I hoped he could have explained a bit more of the fan's switch setting. It was a joy and relief finding MasPro Service to get the job done in less than a weeks time."

"We needed to upgrade the electrical in our mobile home and add power to our garage/shop. I called ASE and spoke to Art. He was able to come out that day and give a bid. Also met me at my son's house later that day to check out an electrical issue. Bids were very acceptable and work was scheduled. Work at my son's was done a couple days later. I requested a later date due to prep work and 2 electricians arrived right on time. I had all new receptacles installed, ran 3 new circuits (AC, extra hot water tank and split a previous circuit), wiring ran for new ceiling lights, rerouting old wiring and neatening wires from a wall removal. Our little garage/shop had only 1 available receptacle for everything (freezer, lights, etc). Now we have 16 receptacles for 110 and a drop cord for 220. We are so happy! Equipment that has been sitting for years can now be used and no more blowing a breaker if too many amps are used. In the house I can plug in the vacuum without having to crawl under the table or move something to get to a receptacle. Art, Jerron and Hayden were great to work with. They all listened to us, made suggestions and accomplished everything we needed. Highly recommend!!!!!"

"I called and asked them to come in and install some new light fixtures, right off the bat they were really polite. They came in the very next day, got the job done fast and did a beautiful job. Will be calling again if I need any other electrical work. Amazing workers and outstanding customer service."

Generator Install FAQs, answered by experts

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.

The average cost to install a home generator is $5,200, but total costs can range from $500 to $18,000 or more. The final price depends on several factors, including the generator's size, type, brand, fuel source, and the cost of labor and assembly. The generator's size is the most significant cost factor, as units that can power larger homes with higher energy demands cost more.

Cost breakdowns by generator type are typically as follows:

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

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

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

To ensure you get the right size unit for your needs without overpaying, consider hiring an electrician to calculate the electrical load of your essential appliances. It is also recommended to get at least three quotes from qualified installers to find the best fit for your budget.

Portable generators provide backup power for essential appliances during outages and are easy to relocate.

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. 

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.
