 Replacement cost of an A/C unit for a 1500 square foot house.

Unit is more than 20 years old, and while it runs fine, it just isn't putting the cold air out like it used to.

I suspect a recharge of the system may help, but want to price out a newer more efficient model.

After going through the local heating/air-conditioning retailer and servicing web sites that want tons of information
ie:
square footage of house.
how old is the house.
what side is the outdoor unit on.
what color is your dog.
finished basement or not.
and on and on...

Then they want all your fucking contact information so that some rotund salesman can call you back eight days later.

Anyone got a ball park figure on what an outside unit would cost for a 1500 sq-ft house? I'm guessing a 2-3 ton unit. Heat is forced air natural gas. This is only to replace the outside unit, not the air handler or any ducting.

Much appreciated.

Depends on how big a "seer" rating the unit you get and brand makes alot of difference.

We spent $2300 for a new unit and evaporator installed. The new refigerant is r403.

Good point, I suppose there is a range of prices to go with efficiencies, just like with the furnace.

Dumb question, but will I need to replace any of the inside equipment due to the new refrigerant requirements? I assume the evaporator is inside the house?

really two parts, the air handler "inside unit" and the condensing unit "outside unit". Your sear rating will be what the lowest rating item is. If you can afford doing both, do it. Get as high of sear as possible in your budget, and buy name brand equipment.

A lot depends on finding a person you can trust not to rip you off. In my case, I lucked into a guy a few years earlier that I can rely on. He charged me 20% over his cost + $800 for installation, which I thought was fair. He even brought over his price sheets.

Assuming that your inside evap coils are leaking (very possible), you'll have to replace those and get a new outside compressor unit, since no one makes replacement coils for something that old. The minimum nowadays is about 13-14 SEER, and it's diminishing returns with the 16 SEER units. You get slightly more energy efficiency at higher cost, so you'll have to do the math.

I would guess about $2500, maybe $3000 for that job.

If you get a unit with the new r403, you have to replace the coil on the inside. R403 opperates at twice what R22 does so you cannot mix. The problem is, from what I was told, replacement parts are getting hard to get for R22 units.

If your ac is 20 years old you got your money out of that one,a new split system is what you are looking for.The main problem for you is you will have to replace the whole system because the new refrigerant is now 410a.410a is not compatible with your old system,so you have to replace the air handler also.You can try calling around and try to find a r22 condensing unit but I don't think you will have any luck,and it would not be worth it if the air handler is 20 years old .As per price call around for estimates,different company's use different equipment.I don't know your area but I would guess around 5 to 6 thou.maybe less.

Get it recharged. A good system will last 20 or even 30 years. Mine was close to 25 when I replaced it and I wish I had kept it going (it needed more freon every year at the end of its life).

A local company quoted me $3950 for a new 3 ton a/c system... AND a 92% 70k BTU propane furnace with tearing out the old monster oil-burner. Still getting bids, but this is the best so far.

Another company quoted me over $8500 for nearly the same thing...

Hey sparse,
Where in Oh are you? I have a buddy who works for VIOX in SoWestOh who guarantees to save you $1K. He does it as a side job on the downlow

That is a GREAT deal. I'd stop asking for anymore bids!!

We got a little bigger system (3.5 ton AC and the furnace was 92%, 80k or 90k IIRC). It cost $5 thousand about 3 years ago.

To the OP, I would say $2 to $3 thousand dollars is the norm around where I live.

Cost figure for my 3 ton unit last year without labor, with natural gas furnace was $1800. No additional duct work. My son is a licensed HAVC contractor. This figure should give you an idea of what it should cost you, figuring in labor, etc. 14 seer.

We had a Carrier hybrid heat pump with NG gas pack backup put in last year. 15 SEER unit, removal of old unit check and repair any duct issues(insulation etc) was right around 6500 or so. I didn't think I would be as happy as iI am with it but it has saved me a bundle over the 15 year old unit that we had. I saw someone said recharge it because it should be good for 20-30 years, I disagree at about 15 yrs or older the maintenance and utility usage costs are generally higher the cost of replacing.

That depends entirely on the type of A/C unit you have, how high of a SEER rating you want, and who you go through. Ours went out last year. After calling around I got quotes from $3500 to $7000. In the end a friend of a friend that does it for a living got us a unit, craned it up, and installed it for ~$2500.
