"The recessed LED lighting installation involved substantial ingenuity as there was no available access to these spaces. David and Austin did a great job with this and came up with a great solution that made smart use of existing wiring and switches. They were efficient, professional, pleasant, and eager to please. David even installed a solar light fixture on my gas lamp post just to be nice. I would highly recommend DNA Electrical Services."

"The tech (Christian?) was very professional and amiable. He had the unit running again fairly quickly and tested it. He took the time to talk to me about operating the generator and a friendly conversation. I hope he comes back next on the next service date."

"Jody Ramon and Brian Owens were the lead men and Justin, a supervisor, and Nick Ecker, a salesperson were active members of this team. Cody helped install the 2nd day. Each of these men were more than I could ever expect. They did their part of the process and worked personally to service us as if we were family. They dealt with every concern we had, worked steadily for 2 and 1/2 full days, and left our home in better condition than they found it. The protected our carpets and cleaned up at the end of each work day. We have had an ongoing service relationship with Airco for over 10 years. So far, every person Airco has ever sent us has really serviced us outstandingly well. However, this removal and installation was over the top!! We really are pleased. The final chapter of the process will be schedule for next Wednesday when the Airco technician and the Sand Springs code inspector makes their final visit. Be sure to note that Jody and Brian have to be 2 of your very best crew members. Chris Holmes was our service man for several years but he now is doing commercial accounts for Airco. Jerry Evans, I believe his name is, now services our HVAC on a twice a year contract we have with you. Chris and Jerry are local Sand Springs residents and have really done our work well over the time period we have used Airco. But, this week with the men mentioned above has just been super!! They did everything and more than was ever promised. So far, we are really please with this big upgrade. For us, it was an extremely major decision and it went so well, thanks to this team that came together on our project!! We are so very grateful!!"

Generator Install questions, answered by experts

As a safety measure, you should always turn off the main breaker while operating your generator’s backup breaker. In addition, you should also switch off all appliance breakers so you don't have a power surge when the main breaker turns back on. And finally, turning off the main breaker prevents back-feeding, which endangers utility workers with the risk of electrocution. Back-feeding could also destroy the electrical circuits of your neighbors if they use the same power network.

To power a central air system during a power outage, the whole-house generator will need to be at least 5,000 watts, and this number will significantly increase for larger units. Check the specific wattage requirements of your AC unit to choose the right generator size. Consider consulting a generator installer to ensure your whole-house generator meets your electrical load needs.

Yes, in some locations, it is required by the National Electric Code (NEC) to have a transfer switch installed for electrical emergencies. In addition to following electrical code, generator transfer switches ensure your home is fully protected during a power outage. By switching the power from the main breaker to the generator breaker, you can seamlessly operate your HVAC, lights, appliances, devices, and more during an emergency. 

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.

Sizing a generator is a careful process that requires calculating the electrical load of your entire house. You have to take into account every device you want to use and their wattage requirements, plus the wattage needed to start them, and look for a generator that can safely run all that at around 80% capacity.

In more practical terms, a small home can run on a 10,000-watt generator (and if you only want to power a few key appliances, much less than that). A mid-sized home may need something between 15,000 and 22,000 watts. Larger homes require 25,000 watts or more.
