"Ken is very nice. Explains what's going on, the process and timelines. Had an issue with my charger (I purchased it myself, he just installed it); even though he didn't have to, he walked me through troubleshooting, turned out to be an issue with the programming on the charger itself. He was communicating with me even after my check cleared to make sure I could charge my car fully. Would hire again in a heartbeat."

"Fantastic work! They installed under-cabinet LED lighting in our kitchen, and it has completely transformed the space. The lighting is crisp, bright, and perfectly placed to illuminate the countertops and backsplash. The team was prompt, clean, and extremely professional throughout the process. Highly recommend!"

"Woke up with no heat! Right before Christmas! Harris responded instantly and sent out someone to check the problem. Due to incorrect installation, rain had gotten into the improperly sealed roof vents, which in turned fried the transformer, inducer and circuit board. They were at my place bright and early the next morning installing a brand new furnace, more efficient and quieter, with a 10 year warranty. Arranged financing and were finished by 3pm. Everyone from my first phone call to the last service tech was professional, polite, knowledgeable and all around pleasant and really nice people. They will be my go to for heating, AC, plumbing and electrical from here on in. Glad I found them!"

Generator Install questions, answered by experts

A 1,500 square foot home will likely need a 15kW to 20kW generator. When deciding on whole-house generator size, add up the total wattage of the devices that you’d like to continue running during a power outage. That way, you can ensure you purchase a generator that can power your necessary appliances or medical equipment during an electrical emergency.

Natural gas generators are designed to run for extended periods of time, such as power outages during a natural disaster. Since there’s no limit to the supply of natural gas, they don’t need to stop for refills. However, generators do need maintenance, including pauses to check and add oil. Constantly running them will also cause a lot more wear and tear, leading to a shorter lifespan.

DIY is possible for basic setups. Professional installation ensures safe and proper electrical connections.

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.

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.
