Recommendations on a new gas furnace
I am planning on replacing our gas furnace, a Holly rated at 80,000 BTU, which appears to be an original to the house (1958). It still works, but obviously we are wasting a lot of money running it.
Our house is a small single level, raised foundation, 3 bedroom, 1200 sq. ft. house with moderate insulation and new double-paned windows located in Southern California. I am looking for recommendations for a forced air furnace that would be right for the size of the house, and one that is very efficient.
Any ideas?
Thanks!

call local contractors.
There is no BEST brand. It's all about the installation. If a good furnace is not installed properly then it will not function properly or last as long as it should. Part of a good installation is proper sizing. Part of a good installation is checking for proper duct work.

Carrier, Trane, and Lennox are some good choices.
The quality of the installation is more important than brand.
As long as it isn't a furnace with the Honeywell Smart valve is should be fine.

Goodman is reasonable...Its all in the install thought as the others have mentioned.

Before replacing the furnace, improve the house envelope. Improving the windows, doors, & especially insulation will pay you back many times over & likely allow for a smaller furnace.
After the envelope improvements, do, or have done, a Manual J heat loss calculation & size the furnace accordingly.

Most replacement jobs I go on I wind up bidding higher to try to correct the inadequate ducting. I would get a lot more jobs and make a lot more money if I just threw them in there and walked away....that seems to be the trend. My brother in Seattle just went through this same type of deal, what a mess when it was done
The new furnace is not very efficient if the air doesn't flow properly, and that's the true fact of the matter.

Where is the furnace/ductwork located?
What does fair insulation mean?
The proper way to size a furnace is to do a load calculation.
Changes are that your current unit is too large.
