Why so many problems with Heat Pump?
I'm looking at purchasing a Lennox system (from costco). All of the energy advisors I spoke with say that heat pump is the way to go.
And from doing some searches on the forum, most will agree that it is not the brand but the installation.
But why are there so many problems being reported with equipment failures for all types of brands? This link was an eye opener!
I’m really nervous about spending $K and upwards only to deal with service calls and repairs month after month! Please tell me that this is not so. What is your annual maintenance and repair cost? Is this going to offset any savings from the heat pump?

i belong to peta ... people eating tasty animals. all my opinions are just mine.
Remember, usually it is one who has problems that find these internet rating sites and complains. And since we are only hearing one side of the story, we have no idea what the truth is. As jpb said, consider the installation. Too many installers are hacks and aren't sizing & installing the equipment properly. That gives the equipment and brand a black eye. Heat pumps are much more complicated than straight cool units and are less forgiving to a poor installation.
But now on the other side of things, customers are beating us down something fierce on price and that trickles down to the product. Stuff these days is so cheaply made and full of lousy 3rd world made components as a result. So yes, today's stuff doesn't hold up like the past either. Until John Q Public is willing to pay for quality, we will be putting out more troublesome HVAC equipment as well as many other lines of products.
Always wise to get an extended warranty backed by the equipment manufacturer. Don't look for the bottom bid and research your dealer extra carefully.
what is your location?
what size are you looking at?
I think there is alot of junk out in marketplace for HPs
these are my minimum specs for a new HP system. both outside and inside units should be replaced to have a properly matched system.
15 SEER, 12.5+ EER, 9 HSPF
best matching VS air handler
full BTUs in both cooling and heating for your rated size
R-410a refrigerant(same as Puron)
scroll compressor preferred
electronic demand defrost preferred
thermostat with "dehumidify on demand" feature
staged backup heat strips
new and correctly sized refrigerant lineset
you want a thorough inspection of your ductwork system. size, overall condition, supply and return lines, insulation qualities, leak test, etc.
any hot/cold spot issues in your home should be addressed.
I would only use authorized dealers for the various brands that provide quotes. see mfg websites.
I would look at Trane/AmStd,Rheem/Rudd,Carrier/Bryant.
I would not purchase a new HP system that did not have electronic demand defrost.
you want a new system that offers a minimum 10 yr warranty on parts and compressor.

A unit that needs to be recharged with refrigerant has a leak - plain and simple, but there are complaints that the system has to be constantly recharged. It is more than obvious no one has bothered to find and fix the leak. That is not an equipment problem it is a hack company that did a great job of hacking the install. Then the homeowner complains about Carrier.
Another complained that the first Carrier equipment had the compressor fail after only five years and they were having problems with the new replacement Carrier system. Again, compressors rarely fail in five years. More than likely the compressor was killed by a poor installation - lack of air flow is one reason, improper refrigerant charge could be another, and there are more reasons. The problems that shorten the life of the first system are still there and the same hack company may well have done the replacement system so the problems just continue.
Strongly suggest that you not go through a major retailer for your new system. Do a search for skippedover on this board and you will find that he has put together a very comprehensive list of ways to find a top notch contractor to do a top notch install. You will have great system with a great install and many trouble free years of comfort.

what is your location? Seattle
what size are you looking at? Lennox XP17 3.5 ton with SL280 LP furnace & Honeywell IAQ duel fuel thermostat.

****I had few retailer come out and none of them did this. One was interested in selling me a tankless water heater, the other didn't even give me a bid, and the rest just gave me a bid without looking at my duct, insulation, leak, etc. After a few of them, I just thought that this assessment and calculations were not necessary since no one did it anyways. I'll go and do some searches on skippedover and see what I find. Got any installers you could recommend?
Of course I have not seen job but price seems questionably high.
plus as another poster said, I would not purchase HVAC through a big box retailer.
Excellent point about review sites. I have plenty of appliances at home that are great, yet I'll never go and post about it. On the other hand, if i wasn't happy with something...
Yep keep it perspective. Lennox sells tens of thousands of heat pumps every year. Some are installed by bone heads who can't follow installation instructions and some just have parts go bad but for most folks they run trouble free for many years. They also offer a 10 year labor warranty at an addional cost if you're really worried about break downs.
