What Is a Whole-Home Generator?

Whole-home generators ensure continuous power to essential appliances and systems, keeping your home safe and comfortable during blackouts.

What Size Generator Do I Need for My Home?

The right generator size depends on the total wattage of the appliances and systems you want to power.

A professional electrician can help determine the appropriate generator size based on your household’s energy needs.

Professional inspections help identify and fix potential issues before an outage occurs.

Every aspect of our experience with Roy’s was refreshing! When I called to schedule an appointment for an estimate I was greeted with a pleasant voice. Adrienne was incredibly respectful, knowledgeable and authentic from the moment she entered our home to provide an estimate. The team that installed our furnace and AC were also respectful and informed us of the installation process before they attempted the work. We look forward to many more years of amazing customer service from this company.

Aarons crew was amazing. They took two downspouts from the house to our street. Their work was outstanding and they were so careful with the lawn. If not for the 1 foot trench going to the road you would never know they were here. I would highly recommend them and will use them for future work.

Everything about my experience with Roy’s is positive. The original estimator who came out, and the three man crew who did the job All highly professional. Did their work impeccably, as promised, no hidden charges or add-ons like with so many contractors, they cleaned up after they were done. Top-notch. Angelo, Joel and Kyle were the contractors and if I need more work at my house, I’m going to request that specific crew. A+.
