Ask Me Help Desk - Goodman heat pump

I just bought a older home, it has a goodman heat pump, it was cycling a lot and wouldn't shut off. So my room mate and I narrowed down to the thermostat. We replaced it with a hunter programmable one. It is cycling fine shuts off and seems to be working fine. I did call a tech in, he never checked the unit outside. Came in and said that Hunter thermostat's were junk. And so wasn't a progammable one. He said he could replace it for 128.00 plus service call. He left to go get it and never returned. So now Im wondering do I have the right thermostat it is for heat pumps and are programmable ones junk. Should I contact goodman and see their recommedation?? Im confused, and not very happy with the company I called.

Brand bashing and no followup; sounds like you need to find a new company to do your HVAC service as this individual did not act professionally In my opinion.

In my opinion Hunter is not my preferred brand but will get the job done. Tell us what model Hunter you have, what is your emergency/aux heat for that Goodman, and we can let you know.

Usually programmable thermostats do not work well with heat pump as far as energy savings are concerned.

I did get a honeywell thermostat, got a different, tech. He replaced a relay switch on heat strip and relay on blower. But my heat pump is running all the time, the blower run continueous. I have it set at 67 and it says 67 and doesn't shut off. The tech is telling me I need a bigger unit, it is 7 yrs old, the condenser and fan was replaced.(prior to me moving in) It is a 2 ton, I have 10 heat ducts in house very small house just a attice. One story. We are adding more insulation this weekend. They are coming today to give me prices on a new unit. I just don't believe this unit is to small, I realize that it has been cold here and its working harder. I feel something is wrong. I just moved in this house 4 weeks ago, it ran fine the first 1 1/2. any suggestion?? I did clean the unit out, in fact they offered me a job, lol, they said I did what they would have done. Thank u. sq ft in house is under 13,000, not sure going to measure that. I feel its high 11,000 or in 12,000

Its impossible for us to tell if you need a new unit, but just to get a ballpark what are your outdoor temps when the unit could not keep up, what are your normal temps for that this time of year (ie where do you live approx.), and what SEER/HSPF is this unit?

It doesn't hurt to get an estimate, but run the other way if they don't do a Manual J (aka load calculation). That is the only way to determine what size unit you need.

If you research and lurk around the HVAC forums you'll find a common theme to tighten your home before replacing a good working system. Sometimes an undersized system can be brought into balance with a home that is tightened up. You can apply these hypothetical changes to a Manual J to get an idea if that's possible.

BTW I think you have one too many zeros on your sq ft.

I live in Florence, Sc, temps at night have been 20, today its suppose to be in the 50's , the temp have been very low for the first time in 5 yrs. Of late. The house is a older home, and yes I did add one to many zero's. And what and where do I look for the seer/hspf. What is a manual j? They are coming today with a estimate. They seem to think a sysytem in the attic and duct week there too, is the way to go. They say I need to go to a 2 1/2 ton and it will need new duct work. And going under the house you lose the heat and cooling
