"Chris and his assistant did an excellent job of explaining the situation and options for repairing or replacing our hot water heater. In the end we chose to replace it and they were able to secure a new unit and install it within 3 hours. Would definitely recommend Chris and Tri-County Services and will use them again if another situation arises."

"On Thursday, the technician (David) came to my house to look at two projects: replacing a leaking electric water heater, and installing a new gas line (in my crawlspace) to my masonry fireplace so I can convert from wood to gas logs. He explained my options, and quoted prices for these options. I asked if he could do the work on the upcoming Saturday, and he scheduled this before he left! I ordered the gas tankless water heater and the gas line to my fireplace. By the way, I had 3 different plumbers look at this work, WyattWorks had the lowest prices. On Saturday David and Alex arrived early in the morning and worked past 6:30 PM to complete both jobs. The installations were great. Everything to code, and with neat, high quality workmanship and thoroughly tested. They cleaned up the work areas and hauled away my old water heater. In other words, a typical WyattWorks job."

"Mr.Electic and Ryan, as well as the electrician, were all amazing. My electric panel burned out at night. I called them at 10pm and they had a representative at my house the following morning. They're quote was within market rates with a bit of an expected mark-up for urgency. It was definitely reasonably priced, especially since i couldn't find anyone else able to do the job right away. Long story short, the electrician was at my house the very next day after the quote and did an AMAZING job installing a larger panel. They needed to cut the wall to make more space and did it in a way that is practically invisible from the outside. You really cannot go wrong with this provider."

Generator Install questions, answered by experts

To determine the right size generator for your house, you should calculate the total wattage of the appliances and devices you want to power during an outage. List all essential items, note their start-up wattages, and add them together.

Here are some typical wattage requirements for common appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 to 4,500 watts

  • Electric furnace: 5,000 to 25,000 watts

A 7,500-watt generator might be sufficient for essentials like a refrigerator, freezer, well pump, and lighting circuits. However, for high-demand items like a water heater or furnace, a whole-home generator is a better choice. A portable generator may be enough if you only need to power a few critical items.

While home square footage can offer a rough estimate, it is not always a reliable indicator. For reference, here are some typical generator sizes based on square footage:

  • 1,000 sq ft: 6–9 kW

  • 1,500 sq ft: 7–10 kW

  • 2,000 sq ft: 10–14 kW

  • 2,500 sq ft: 12–16 kW

  • 3,000 sq ft: 16–20 kW+

For the most accurate sizing, consult a professional who can calculate your home's peak and average power consumption and recommend the optimal generator.

A home that is 2,500 square feet will likely need a 20kW to 25kW generator. Consult your local generator installer to confirm the generator size needed to power your home before purchasing a new one. Be sure to consider how much power your necessary devices need to run.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

You can expect a diesel generator to last for up to 30,000 hours of use, which works out to 20 to 25 years with the proper maintenance, of course. That depends on how much you use it, so a diesel generator used for emergencies a couple of times a year will last a lot longer than a generator that takes over for a faulty electrical grid every month for a day or two. 

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.
