"Professional, serious, and effective. The exhaust fan/light was installed in our bathroom, with a good ventilation plan to take it out the side of the house. The work was performed well, they cleaned up afterwards very thoroughly, and we're quite happy with the results."

Customers say: Quick response

"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

Many services include assembling the unit and securing it in the window. Confirm with your provider.

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.

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. 

In many cases, yes. There are models called dual-fuel generators and fuel switches, but only between certain types of fuel. For example, with the right setup you can convert a generator from natural gas to propane. Some allow switching between diesel and gasoline. There are even tri-fuel generators available in some cases, which adds a large layer of security if you are worried about fuel availability in times of crisis. Always check your generator capabilities and manual instructions before trying to switch fuels. Some generators can use another fuel but may need a fuel conversion kit to prep them first.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.
