"I recently had an electrical inspection done by TE Certified Electrical, Plumbing, Heating & Cooling, and I couldn’t be more impressed. From the moment the technician arrived, the experience was professional, thorough, and reassuring. They took the time to explain everything they found in a way that was easy to understand, and I felt confident I was in good hands. What stood out most was their attention to detail—they didn’t just check the basics, they inspected the entire system to ensure my home was safe and up to code. No high-pressure sales, just honest advice and helpful recommendations. I’ll absolutely be using TE Certified again and would highly recommend them to anyone looking for top-tier electrical service."

"Keep Smiling sent me Roy Wint and I'm very glad they did. Roy installed a replacement ceiling fan as well as four recessed lights. The result of the project is a much better lit and livable living room. I want to extend special kudos to Roy. He was very professional, polite, and friendly. A joy to have working on my home. He went out of his way to avoid creating any holes in the ceiling other than those housing the lighting fixtures. And he also did a safety inspection of my home's fuse box. I can't say enough good about this young man. I'll definitely be calling him the next time I need electrical work done in my home."

Generator Install questions, answered by experts

If you have a transfer switch properly installed, the generator and main electrical power cannot feed the system at the same time. However, you should still shut off the power at your main circuit breaker panel before activating the generator. If you do that, you’ll simply need to shut off the generator and reset your circuit breaker once the local power comes back on.

Energy output depends on turbine size, average wind speed at your site, and system efficiency. A 5 kW turbine in a good wind location can generate 8,000 to 12,000 kilowatt-hours per year, which may cover a large portion of an average home’s needs. Accurate output estimates require a professional wind assessment and a review of your household’s energy usage patterns.

When choosing the right size generator for your needs, consider a few items to help calculate the wattage you’ll need. Start by determining which household items and appliances you want to power, and then add the wattages together. Check out the wattage of these essential appliances:

  • Refrigerator: 600 watts

  • Large dehumidifier: 700 watts

  • Large window air conditioner: 1,400 watts

  • Water heater: 3,000 watts

Running home appliances like these requires a partial or whole-house generator. A portable generator may be enough to power your home if you only plan to keep a refrigerator and freezer running. 

While standby generators provide essential backup power, they can fail when you need them most due to lack of maintenance, fuel supply issues, dead batteries, electrical problems, or improper installation. To avoid costly failures, professional installation and regular maintenance are crucial. Licensed technicians ensure safety, uphold warranty requirements, comply with regulations, and provide expert servicing.

A 10,000-watt generator can run a small to mid-sized central AC unit (typically up to 3 tons or 36,000 BTU) along with a few other appliances. However, larger AC units or additional loads will require a bigger generator. Consult a local generator installer to ensure you add the correct size generator to your home.
