We just got a new heat pump installed yesterday, November 14 in Columbia, South Carolina area. Tonight is the test night. 45F (+6C) outside and the heat pump went on and it's been on for an hour without stopping even if I set temp to 68F and it got like 64F in the house. The thermostat shows temp 66F but in other rooms temps plummeted to 57F. Our noses are already running. The heat pump blows very cold air which does not feel warm at all. The heat pump "HEAT" mode is on, everything set up correctly on the thermostat. As soon as I turned the "heat" pump off it felt much better having that "freeze pump" stop blowing cold air into the house. I put three electric radiators on and we are "ok", but I'm "mad" that the brand new expensive heat pump blows cold air into the house. The installers said they inspected the ductwork under the house in the crawlspace, but I see that the access to the crawlspace was never opened... Was patient enough to wait to see if any heat comes up, but nothing, just cold air... brrrr... I'm still freezing just thinking of being foolish removing that old propane heat furnace (which was very very expensive to run, the cost of propane is pain costing $600 to $1500 a month or so) and the old 16 year old CARRIER a/c with this new xxxx worth of GOODMAN heat pump which seemed to be like a dream machine at 14 SEER and paid big bucks extra for the R410A refrigerant unit and a VARIABLE SPEED BLOWER MOTOR AIR HANDLER! Condensing unit Model # SSZ140481AB. Furnace ar handler: Model # AEPF426016BA. 15 KW coil. Isn't that a good equipment? Although I noticed how much more nouce it makes in comparison with the propane (gas) furnace. Propane sure felt like real heat, but we needed to get rid of it as it was becoming way too expensive. But why is this heat pump blowing no heat, just cold air? I mean I'm familiar with "cold air" coming out of heat pumps which eventually heat the house, but this one's air is way too cold and it actually cooled down, at least it felt like we are cooling down instead of heating up. The aur coming out feels like 50F or so. Please advise, we are freezing. Called the installer's service "emergency" number, but no one is there, I guess at 2 AM is a bad idea to have trouble with heat pump. Will have to wait until the morning, at least another 4-5 hours, which is fine with me. The H/P is off. The radiators are on. What was the xxxx paid for?
