What size AC, how much should it cost?

Question

My house was built in 1984 and the AC/heating unit has broken for good so I need a new one. The old unit is a 24000 BTU unit with no SEER rating, because it's so old. Everyone I have talked to says replace the heat pump, central air, air handler, dehumidifier, etc. all at once.
I live on the Eastern Shore of MD, for climate reference.
My home was built in 1984 it is a split foryer that is 1600 sq ft. All of the windows and doors are original.

Could someone please give me some advice on;
1. How big should the new unit be (tons)?
2. What SEER rating I should get, value to cost ratio? I'm trying to save money here.
3. If I can install it myself ? I have an electrician friend and a plumber friend at my disposal.
4. About how much the whole system will cost? (Ballpark) I need to save up for it.

I guess I am luck that the old one lasted as long as it did :)

Any help is greatly appreciated.

Thanks

Answer 1

In tonnage as opposed to BTU an industry standard in 1 ton for approximately every 700 - 750 sq. ft.

With decent insulation your unit should be probably 2.5 - 3 ton.

Any less will be dissatisfying, and less efficient; any more might be wasteful as well.

I've never bought one to self install; but have to believe $1000 per ton would be a fair estimate, plus labor.

Go to your electric company's internet website... as per state/federal mandates they explain the whole seer/BTU, your options and the energy-efficient systems that qualify for rebates (and Federal tax break). No matter who you buy from, you need to try and find your local distributor (again search the internet)--their rep will look at your situation, give you the options, contract the installers (backing their warranty), and even payment plans. Replacing an existing AC is no big deal, but a whole FAU system is asking for brain damage and usually voids the warranty. In the long run, a heat pump system probably would be your best choice, as I know those cold air fronts can really run up the bill (heat uses more energy than AC). Good Luck!

Before you buy go to www.hvac-for-beginners.com . Start with the page on air conditioners and it will take you through the whole process. As far as price for just the ac unit it would probably be around $2000.
