I have a 32 year old Air Conditioning system. It works fairly well but I’m having it cleaned and serviced today I learned I’m low on R22 Freon which will cost over one thousand dollars to replace. And they will have to find and fix the leak which they said is probably in the coil and a new coil is over a thousand installed so I’m looking at about a 2,500 repair.

They suggested I use the 2,000 tax credit on a new heat pump. With the tax credit a heat pump will cost about the same as a new air conditioner.

I live in the suburbs of Atlanta so I’m more concerned with cooling than heat.

What does the OB recommend.

1. Pay $2,500 to replace coil and get refill on R22 for a 32 year old AC unit.

2. Get a new AC unit.

3. Get a new heat pump.

My summer electric bill went down almost $130 a month after replacing the original AC unit from 1992.

I replaced my 20+ year old ac with 18 seer heat pump and I've been very happy with it. My electric and propane usage has gone done. I do live in a more moderate climate than you however.

Either way I would go ahead and replace the old unit before summertime

I would never sink any money into an old 22 system. What type of heat do you have now ?

It’s 32 years old. The next time it breaks it’ll probably be 90+* outside

Your job should come in at about 10 thousand, with basic seer 2 level equip, heat pump, new 4 ft sheet metal cold air plenum, normal support items.

2 stage, higher seer, etc. probably a little more.

With a heat pump, you will want the Hspf rating at .8.8 or higher. That is achieved by more coil on the outside unit, which means high seer on the AC too. Likely 16 seer 2

You can replace it if it isn’t broken but don’t think you’re going get a + return on your investment. That new unit isn’t going to last 1/2 as long what your current unit. The metal is a lot lighter and corrosion is going to eat through your coils a lot faster

I have a furnace for heat now. It heats very well.

I did notice my AC was running more last summer to keep the house cool but I guess being 32 years old and 6 pounds low on refrigerant will do that.

This is frustrating because I wish I could just fill it with cheap refrigerant every April. Like the good old days.

Check into a ducted mini split system. That's what I have and it's amazing at how little power it uses.

Exactly this. It's the dirty little secret. Sure the monthly electrical savings is great, but takes about 10 years to offset the $12k you spend on the new system. But then that system has to be replaced because they don't last more than 10 years, so you never really save money long term.

What is your current heating system? If it's gas, get an AC. If it is electric resistive heating using the same fan plenum and ducts the AC uses, get the heat pmup. They should set it up with auxiliary resistive heating as well.

4. Get second opinion and new quote.


A new system last 8 years or so. Keep that old one running till it shits the bed.

If I have to replace my unit, this is the first thing I will consider. Kind of stupid to cool the entire house when you're basically in one or two rooms during the day/night.
