i have heat pump thats not giving decent heat i retired from new jersey to virginia 4 years ago and from a traditional heating air conditioning system . now i have heat pump in new house and confused by it and how it really works . it is a 12 seer 4 ton unit in a 2440 sq. ft house with 2x6 stud walls but the house seems cold . i have added extra insulation in the attic but still chilly in here . the house was built in 2004 . is it just me or this heat pump or should i change it out for a traditional heating and air unit . HELP FREEZING IN AXTON VIRGINIA .

Re: heating

Heat pumps in a nut shell extract heat from the outdoor temp and transfer it through the refidgeration system-if you felt the back of a freezer you will notice it feels hot well thats a heat pump in reverse.Now how much heat can you retrieve from 50 degree outdoor air-quite a bit now below 30 degrees the amount reduces and at 20degrees the electric heat strips that come with the air handler need to come on. the bottom line is unless the heat pump is super tuned there is a point when it needs to be turned off and only run the secondary heat.Most design temps in the south work for heat pump limits except the extreme end of the cold scale, which only happens a few design days a year. Those few days are hard to be comfortable wear a sweater.
Of course you could have a bad defrost board of something malfunctioning which is why is said super tuned before.

call a tech to be sure other wise there is a dual fuel system out there that has gas instead of electic heat for a back up.
And you can't beat fire for heat. so the running cost overall may be cheaper for a heat pump but you may be a little uncomfortable.

we live in a rural area no gas here only electric or propane which is expensive . will it hurt running it on the reserve heat for extended length of time like 2 or three days the repairman only put freon in it . and was telling me that these units do not last that long and they do not sell service contracts , like i had on my heating unit in nj . i was able to only ask him a few questions before he had to go to another job . seems they don't have hardly any people to work on these things . is the unit big enough for this house . the floors where also insulated in the basement and i put on a vapor barrier down there too .i'm not sure what else to do . i had housewrap put on also when the house was built .

Re: heating

It would be better if there was more than one unit meaning zone the house -2 tons and 1.5 tons but you have what you have. The unit may not be tuned correctly seeing how you said the tech said they said had to add freon. the best you can do is run the auxillary heat until the warmer months . It won't hurt the unit just your wallet. Sorry this appears to be the case. This sounds like wham bam thank you mam.
If you live near Manasas call Seaboard mechanical if you are lucky they will answer. Other than that I don't know any other HVAC contractor in the area that have a reputation.
Good Luck....

thank you for your help but i'm 15 minutes from north carolina . i'm on the southside near martinsville speedway. might have to bite the bullet and change the system out . oh well live and learn . but still thank you again . if i do change it what would be a better system or company to go with and which might give me a contract with the unit . any help would be appreciated .

Re: heating

I would say go to company that has been around at least 5-10 years, some companies are unit specific reps or dealers.Trane Carrier (bryant),York (coleman), Lennox ; roll the dice with one of these. There are cheaper units but the service is also a big part of the product line of which parts will be easier to get as well as a dealer... although there is a lesser name unit out there-Goodman that has a 10 year warranty parts and labor....good luck
