    leaking r22, repairman just put more freon. What to do now?

    so we recently got a house in Austin, TX (Built in 1997), and found out the AC wasn't cooling. our 1 year home insurance came and went. the repairman for the insurance said there is probably a leak and just refueled the freon, approximately 4lbs as he said the insurance wouldn't cover finding the leak and fixing it since they usually don't. this year called a service repair guy and talked to him for a bit, gave me a couple different options about replacing the unit but no mention of finding the leak. said theres definately a leak and took a look upstairs at the heat pump but didn't know where it was. refueld the freon again 4lbs and charged $xxx for the call and freon. now i'm thinking if i need a new unit down the road as the current trane xe1000 whines a bit when turned on compared to our neighbors units. Will a 13 seer or greater will pay itself off in efficiency in 5 years?

    any help is much appreciated. sorry if this isn't informative as i'm not really sure what's needed.

    1) Is this a total electric w/ heat pump?
    2) equipment original to house and matched?
    3) Can you post the model numbers for indoor & outdoor equipment?
    4) What were all the options suggested by the repair guy?

    OK,

    so the system is 14 years old. You can have a leak check done just to make sure it isn't something minor like a service valve cap, etc. I truthfully doubt it though, judging from the amount of refrigerant added each time to the system. Or, you can go ahead and get prices on replacing the system. Usually what I find is a leaking indoor coil.

    1) Is this a total electric w/ heat pump?
    Yes, unfortunately all electric with heat pump.

    2) equipment original to house and matched?
    as far as i know, Yes original equipment since the house was built in 1997.

    3) Can you post the model numbers for indoor & outdoor equipment?
    will respond when i get back to the house, but the outside model unit is a trane xe 1000

    4) What were all the options suggested by the repair guy?
    his suggestion was to replace the condenser, but that was about 3k and didn't guaruntee that would fix the leak.

    5) Heat pump change outs REALLY need to be matched.

    you might like to check out the AOP Contractor Locator map on this
    site, there is a Pro in your area from this board.

    6) Do not panic, choose wisely, I'd want to know where the leak is before I made any decision.

    here are the model #'s for both Trane units.

    Heat. Pump: TWE048C140B3
    Ac: TWR048C100A4 - Date on the unit was 12/97

    is there somewhere i can look at that explains what the heat pump does besides move air? besides replacing the filter is there anything that needs maintence? Since i've moved in just sprayed the coils on the outside unit and made sure too many leaves weren't around it since an oak is about 5 feet away.

    Good site with lots of heatpump info. Personally I would get some quotes on replacement but give it some thought first.
    Like how long are you going to live in the house? If more then 5 years you might want to consider a higher seer rating.
    In HVAC I think most here would agree you get what you pay for, do some research, educate yourself. Find out what contractors around you sell what products, and research them, contractors and equipment.

    Good Luck

    I ran the information you gave me through a website called hvacopcost.com. It gives a comparison and estimated yearly savings. going from your 10 to a 13 seer says $411/yr that is only figuring the cooling season though. you should visit that site and play with the numbers.

    In addition to the savings from operating a higher seer unit you can enjoy
    the comfort, peace of mind and a system under warranty. A win - win.

    Wear out your old shoes, buy some new ones. How long's the pay back?
    Buy a new dining room set. How long's the pay back?
    Buy a new hybrid car. How long's the pay back?

    Why do people always try to shoehorn HVAC equipment into "how long's the pay back?" Doesn't anybody make the purchase for greater comfort? Must it always produce a financial reward?

    just a correction, looked back at my notes and the first repairman said it would most likely need a new evaporator coil. Since i asked about new units, he suggested a payne (carrier co) unit for the cost instead of going with some of the other brands.

    Any comments on payne units? he said they were a little louder but haven't had any problems so far.

    Thanks smittyii, just looked at the map and it seems you were in San Marcos, you do calls to Austin, TX even though its far?
