Hi

I have a 50+ year old home and would like to install central heat and air.
Home is located in Southern CA and is about 1800 sq. feet, single level.
There is no current system other than a gas wall heater. I have room in the
attic to run ducts and a closet at the end of a hallway in the center of the
house for the forced air unit. The closet area is about 34 by 34 inches. The
closet will have to be demolished to build a new closet specifically for the
HVAC.

My questions are:

Will the closet need a dedicated outlet or can I tap into an outlet on the
other side of the wall (which would be a kitchen counter outlet).

How large of a unit should I need for about 1800 sq ft.?

Can rooms or sections of the house be "zoned". (I have a 400 sq ft
family/game room that does not need to be cooled/heated unless it is
occupied.)

Will I need to pour cement to level the area for the compressor? Their
already is cement on the side of the house but it is sloped 10-15 degrees
for drainage.

Will a new flue be necessary for the heater. The existing flue for the old
wall heater is about eight feet, (down the hall) from the closet so can it
be used?

Since the house is old (built 1951) will I need another power drop.
Currently the house does not have a 220V outlet. Their is a natural gas line
running through the current closet area going into the kitchen.

I'm thinking of a Carrier system like the Infinity 96. Any good or bad
reviews???

What should I expect to pay??

Thanks for the help!!

Martin.

I would like to make it clear that I will be having a professional do the
install. I understand that this is not a typical DIY job.

First off and most important...ignore Stormin Moron...hes got no freaking
clue what a job in CA consists of.
Second, you better get a licenced guy to do it, or you will find out real
fast how much you didnt save when you get hit with fines there.
And make DAMN sure you have a licenced company do it. check with the FTB
(Franchise Tax Board) to insure you are working with a legit contractor.
Ask if they insure Title 24 requirements...insure they do a load
calc...insure they do a duct calc...check their insurance, check their
workers comp...etc..

Depends on if you are a homeowner, or repair tech.

Alot.
Title 24 really kicked the prices up out there.
And its gonna depend on WHERE in SoCa you are at.
LA will be different from SD, PS will be different from Landers...

Bullshit. You'll only get a professional in after you get fined or
after you find yourself in over your head.

Hi

I have a 50+ year old home and would like to install central heat and
air.
CY: Excellent idea.

Home is located in Southern CA and is about 1800 sq. feet, single
level.
There is no current system other than a gas wall heater. I have room
in the
attic to run ducts and a closet at the end of a hallway in the center
of the
house for the forced air unit. The closet area is about 34 by 34
inches. The
closet will have to be demolished to build a new closet specifically
for the
HVAC.
CY: You sound serious. Good job, sir.

My questions are:

Will the closet need a dedicated outlet or can I tap into an outlet on
the
other side of the wall (which would be a kitchen counter outlet).
CY: The heating plant/ air handler should be on its own 15 amp
circuit.

How large of a unit should I need for about 1800 sq ft.?
CY: Not being there, I can't be sure. However, I'd guess 60,000 BTU
heating, and two tons cooling.

Can rooms or sections of the house be "zoned". (I have a 400 sq ft
family/game room that does not need to be cooled/heated unless it is
occupied.)
CY: Should be able to get vents that close.

Will I need to pour cement to level the area for the compressor? Their
already is cement on the side of the house but it is sloped 10-15
degrees
for drainage.
CY: The compressor needs to be level. How you do this depends on you
and the contractors.

Will a new flue be necessary for the heater. The existing flue for the
old
wall heater is about eight feet, (down the hall) from the closet so
can it
be used?
CY: If you get a 90 percenter, the installers will use PVC pipe for
the flue, which is relatively painless technique.

Since the house is old (built 1951) will I need another power drop.
Currently the house does not have a 220V outlet. Their is a natural
gas line
running through the current closet area going into the kitchen.
CY: It is possible that your house has 220 volt capability which was
not yet used. Your local contractor can answer that for you.


I'm thinking of a Carrier system like the Infinity 96. Any good or bad
reviews???
CY: I've never worked with those.


What should I expect to pay??
CY: If you use illegal criminal border jumpers for labor, about
$3,572.14. If you use union guys who actually do the job right, I'd
expect $5,146.39.

Thanks for the help!!

Martin.
