"I cannot stress enough how impressed I am with their commitment to customers. After the installation of an outlet for an EV charger and an upgrade to my panel, I had a minor issue. Within an hour of me reaching out to inform them of the issue, I received a call with an offer from Endrite to come by later in the day to take a look. The repair was done at my convenience with no additional charge. They were thorough and went beyond what was probably needed to ensure the problem did not re occur."

"Greg the owner of Papa Grieves is an amazing, incredibly honest and dependable pool expert. He came to my house on Friday to repair my propane heater. The heater needed 2 parts and Greg only had 1 of the required parts on his truck. He called me, explained what needed to be done and that he would come back on Saturday to finish the job. Greg said that although the heater had a great deal of rust, he could fix it so that it would work for the remainder of the season. He did NOT try to see me a new heater, but I asked him what a new heater would cost. The price he quoted me was 20% less than what my current pool company, that did not return my call about my heater not working gave me at the beginning of the season. I asked him if he could install the new heater on Saturday, because I was having a big party on Sunday and he said the heater was in stock and that he could do the job the next day. Saturday morning the rain was coming down in buckets and I did not expect Greg to show up. But to my shock and amazement, at 10 AM the Papa Grieves Pool truck pulled into my driveway. In the pouring rain Greg and his assistant Raul removed the old heater and installed the new one. They performed all of this work without asking for a deposit or credit card for security. The heater works great. PARTY SAVED!!!!! That you Papa Grieves!!!!!"

Generator Install questions, answered by experts

No, you should never plug a generator directly into a wall outlet in your house. This practice is extremely dangerous, often illegal, and can cause "back-feeding," where power from the generator flows back into utility lines, creating a life-threatening hazard for utility workers. It can also damage your home's electrical system, including appliances like pumps and HVAC fans. If the main power is restored while the generator is connected, it can destroy the generator and cause an electrical fire. To safely connect a generator, you must use a professionally installed transfer switch or an interlocking kit, which prevents back-feeding by disconnecting your home from the utility grid before the generator provides power.

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

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 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 need to be installed on level ground several feet away from walls and other objects. Because they tap into the electrical system directly, they usually need to be close to your home electrical panel for a transfer switch installation. It also helps with installation if they are near to a gas line or propane tank installation.
