"Dan and his team did a fantastic job. My initial issue ended up being a lot more elaborate than initially anticipated but I was so pleased with their initial work I hired them again to address the larger system issue. I absolutely recommend and will definitely look to hire them again next time I have any electrical problems."

"We loved going with express essential services. The receptionist was very nice and was up front and honest about what there policies were. She gave me a day and time for an evaluation (they had a technician there exactly when she said). Our technician was great he quickly diagnosed our problem and got in touch with the company. Before he had even left the receptionist was calling me back with the price to fix it and a few available dates. We got a date booked to do the work I sent the deposit and within a week they were back fixing our chiller. It took a few hours and our unit was back working like new. Id highly recommend."

"THEY INSTALLED THE FURNACE AND A/C IN ONE DAY'S TIME. WE WERE VERY SATISFIED WITH THEIR WORK WITH A FEW MINOR EXCEPTIONS. THE NEXT DAY THE OWNER HIMSELF RESPONDED TO MAKE THE CORRECTIONS TO OUR SATISFACTION. I THINK THEIR PRICES WERE VERY REASONABLE FOR THE HIGH END EQUIPMENT THAT WAS INSTALLED (TRANE)."

Generator Install questions, answered by experts

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. 

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.

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

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.
