There shold be a grey, 6x6" box into which the gas line enters and to which
the thermostat is connected (I forget its name). This is the "brains" of a
gas-fired system and can be obtained from Graingers for about $35.
Check yours out - it may have a button that says something like "turn on the
gas anyway."
I had one that refused to work until it got a couple of sharp raps with a
broom handle. Eventually it got replaced and all is now well.

IMO, he's giving you BS. If the water heater "had a couple of leaks" it
certainly did not repair itself. Replacements should be half or less that
what was quoted. If he is screwing you on the water heater, he is driving
in even deeper on the furnace.
Get another guy out there for a second opinion.

Thanks all, have two more opinions lined up, may go for more.

Get several estimates on the same equipment. Installation is going to be
your biggest concern.
Off hand, I couldn't afford to live in LA, with prices like that!
I just replaced my own HW tank, ran me $450, and I was having a cow because
the last one was under $300. They changed the ignition, EPA regs or
something or other. But $1,500 for a gas fired one seems awful steep.
There's not much to installing one.
It's been 5 yrs for a furnace change out, along with A/C changed out. At
the time I had a 80% Carrier 2stage gas fired furnace, plus 11 seer a/c
unit installed. All 3 companies did a manual J? or something or other.
Ironically, 2 companies recommended the exact same equipment. The one
company came in almost $2,500 higher, than the other company. I flat out
told the guy he was that much higher. He asked the other company, said he
started out working for them, and didn't have 1 bad thing to say about
them. Just wondered how they could do it that cheap. I got everything
installed, plus permit for $5K. They had to do some new duct work since I
had an EAC installed also. Forget what the EAC ran me, but the duct work
was included in the price of the furnace install. Everything was phoned
into the shop for the sheet metal work, delivered within a couple hours.
Was a pretty neat operation, the 2 guys worked like a well oiled machine
together. Parts guy delivered the equipment, then brought the sheet metal &
took away the old. Very well organized company. The 2 installers belonged
to different unions. One was pipefitters, & I totally forget the other one.
I thought about going with a higher rated furnace, but heard pros & cons
about it. Mainly cost and how long it would take to get back.
I heard a/c has to be at least 12 seer now.
Do yourself a huge favor, and get several estimates, on comparable
equipment.

Duh, the other one belonged to the sheet metal union.
