In theory how long should a heat pump last?

So back 5 or so years ago I have my whole heating and cooling system replaced with a 3 ton heat pump. Well after about 2 years the compressor went bad but was under warranty ya right that cost me $750 under warranty the new system cost $4800. So last night it stopped working again. 103 out today and burning up. The first central air system I had lasted over 14 years but this one less then 6 so what the heck is going on with stuff now days?? 15000 BTU as in 3 5000BTU window units just does not cut it.
 
Mine is a Bryant installed in 1980 and works great TO THIS DAY ITS never been touched or re charged or nuttin...........BUT I had another installed years later and it only lasted a few years....The service tech told me due to efficiency standards they kept making them with lighter walled copper and and thinner heat exchangers (betetr heat transfer) so the new ones aren t holding up????????

My brother does HVAC and he doesn't have a good word for any newly-manufactured brand out there. Just go ahead and try to find one with a compressor made in USA.
 
We bought a doublewide in '01, had heat pump serviced twice in the last five years, last year it failed completely to the tune of $2450.00 for a new unit. Like they say, "They don't make 'em like they used to."
 
Betcha it's a Carrier, isn't it?? I've got at TRANE...heat pump installed in my new house in 1988...no re charging, no check ups, no nothing...still going strong...Nothing can stop a TRANE!!! Cmore
 
The "first" evaporator in my house lasted 4 years. They were making them in Mexico and had pinholes show up. That was a Bryant, replaced it with an Amana.
 
We have a CONEX container at one of our remote bases that has to be at least 40 years old and the heat pump on it works like a new one 24/365. "Uncle Sam buys the best".
 
Well I know with what I have I may be going to small claims court since I have had this system and had problems from the get go. As it is the system cost me half of what I get in a year and hard to pay for something when half your income has to go t it and then another $300 a month for power to run it
 
Mine is 32 years old,don't use it for warmth much except for a backup as we heat with wood.AC still works very nice,when we have electricity.
 
I've had mine three years and he's been here three times to refill it with freon. Yesterday he had a sensitive detector, but couldn't find a leak anywhere. Where does it go? Could it maybe be a leak in the A frame in the plenum chamber? How would/can we know? Would a can of sealer help?
 
My system has been in year round use for 12 years in central minnesota. Except for some minor electrical problems, it has been problem free. We have our backup systems turned off and it is our only source of heat and cooling.

The firm that installed it installed abour 20-25 units a year at that time and when I last talked to the installer about 2 years ago, he had yet to replace his first compressor. His oldest unit has been in service for 28 years at that time.

My pump is made by Flordia Heat pump (FLP)
 
and with the cost of copper, it helps to contain costs. On the new high speed compressors vs the old 2 cylinder jugs we had back 20 years ago, I'll take the new ones in a heartbeat.

I had a Bryant installed 9 years ago when I built the house after the twister. First 8 years was good. Just had my 7th service call in the last year. Last call was a different HVAC contractor. Gave up on the previous one that installed it, and they are the electric company that supplies my electricity. They should stick with that and get out of the HVAC if you cannot support it properly.
 
Part of it is the thinner more effiecient tubing. Part of it was the fact that Every manufacturer jumped on the china parts wagon. They have all had to run from the early chinese vendors because falure rates were too high. Quality has been improving some over the past year or two but it will never be what it once was. Most manufacturers have a ten year warranty now so they should last 10 years and 2 day's before it's time to replace.
 
I put a heat pump in my build 17 years ago. This spring the compressor went out. My serviceman made the statement that compared to air conditioner it would be more like 34 years of service, because it is running in both the cooling and heating season. Made sense to me.
 
In 2010, R22 was taken off the market. So you will be lucky to find parts for the old heat pumps. The new EPA approved freon will require everything replaced, because the pressures may be around 5-600 psi. Everything is different. The copper has to be thicker, not thinner.

As for how will a heat pump last, depends on where you live. Say in Florida, the compressor may be used almost year around. If you live in northern states where the summer A/C is less, you will get more years.

If you want a good opinion on how long they last in your area, ask a realitor or a building inspector that works for a realitor.

If you crunch the numbers, replacement cost of heat pump, service calls, the fact you can't use it when temps get really cold, you have to switch over to electric toaster heat, the number hours the compressor is good for, you won't sell me one. Some places, you will need to go geo heat pump if you want them to work.

Heat pumps are a cold heat source too, lucky if the temp is around 85-90.

The cost of my electricity is so cheap, a heat pump isn't worth it.
