What is the best brand for natural gas stand-by generators to do the whole house

We've used Kohler generators for years and had great experiences both from the sales staff and the service staff. They have great options now for the transfer switches with options for locking out specific loads without having to go to the expense of a separate generator panel. The specific size/design/installation is best left to your professional electrician- Good luck!

How many kW is the house going to draw?   Generac probably has the biggest market presence but if were going big, Kohler, Onan, and Cummins are great.

Generac, Kohler and Briggs Stratton control about 90% of the residential standby generator market in the US.  All three are established manufacturers with broad and reliable product lines.  A more important consideration might be standby generator control systems - modern CPU-based controls make it possible to serve more loads with less capacity than older on-off only controls.  

Getting to the best match for each individual situation requires sales technicians who stay current on changing generator and control product lines as well as basic residential wiring.  

Here are some questions you should hear from your sales person:

  1. Do you require your heating system to operate during power loss?
  2. Do you require your air conditioning system to operate during power loss?
  3. Do you require your domestic water heating system to operate during power loss?
  4. Does your house depend on a private water supply system?
  5. Does your house depend on a private sewage disposal system?
  6. Is natural gas available to your property?  Do you have LP gas service in your area?
  7. Do you have special standby electric power needs?
  8. Based on a complete list of your standby electric power requirements, please arrange the loads in priority order.
