Solitaire furnace. Emergency heat runs along with the heat pump. Why? It’s everytime it’s not because the heat pump can’t keep up. They both run together everytime.

Qfan asked:

I have a 15 year old Trane with a Honeywell 7500 thermostat. The problem is that even when the heat pump is off the split system fan still runs and pumps cold air into the house. The thermostat has the fan set to auto. If I flip the circuit breakers to the heat pump and turn it back on, the fan operates just fine. But the problem randomly returns after a while and the fan won’t stop again. Any ideas where this problem is originating from and how to fix it? Thanks!

The other night I was awakened by a clanking/flapping noise from my heat pump (all electric).It was 3 AM, so I just shut it off to stop the noise plus avoid any further damage.I called an HVAC place in the morning and they came out.Guy diagnosed it as being the compressor being shot (basically on it’s last legs).He said I can make it through the winter by using emergency heat.Yes, I know it’ll cost more to run and he said it would too, but said it’s really not THAT much more.He said a new compressor would be aprox $1500.But since my heat pump unit as a whole is 20-25+ years old, it might be a bad idea to put a new compressor in a unit so old that something else just might go in the near future.So, two questions.By running emergency heat through the winter, will the ‘coils’ or ‘heating strips’ burn out over time?How long?Is it safe to do this for the rest of winter?And 2, how much does a new heat pump cost?He quoted me aprox $5200 installed.My place is only 750-800 SqFt.Is $5200 legit?
Thanks for the response. I keep my heat at around 62 degrees. I’m always hot, so I hardly use the heat anyway. My therostat has an option to keep it on Emergency Heat. So, there is a setting for Heat, Emergency Heat and Heat Recovery. He said to keep it on Emergency Heat. This totally stopped the noise, so he knew it was the compressor. And when we turned on the A/C, the rumble noise started again. So, the rumble noise stopped when on Emergency Heat. We could also hear it directly in the unit itself. I know come spring/summer, he said I’ll basically be without AC or will have to put up with the noise until it just gives out and dies. That’s why I’m just hoping to survive this winter and then get a full new unit. I have about ZERO funds right now to put a new unit in at present. So, I’m just hoping to make it through winter. He says I will. I’d imagine if he had any doubt, he’d try and sell me on a new unit today.
Thanks ControlFreak. Any idea how much more a month I’d pay for using emergency heat? Right now, my electric bill (and my whole place is electric) is around 65-70 bucks a month. Am I looking at something like 70-80 or more significant a jump like 90-100+? Thanks again.

Sheila asked:

We are considering central air and heat for our old house. I know very little about heating and cooling. The two current estimates are for a heat pump with back up gas furnace. The heat pump provides heat and air conditioning, with the gas furnace kicking in when it gets under 30 degrees (we live in Missouri). I do prefer gas heat, as it is a warmer heat, but my sister told me some people are not satisfied with their heat pump, not keeping the house truly warm. The heat pump does cost more to install.

chris asked:

I just bought a house that has a heat pump (only electric service to house). The heat pump and air handler are both original…23 years old. I am getting ready to request estimates to replace the heat pump. Should I also be replacing the air handler?

I have never had a $250.00 electric bill in townhome style apartment. Recently my elec. bill increased last month from 105.00 to 250.00 all of a sudden. There are 2 people living here, but since the 1st elec. bill at $250.00, we have cut off all the lights and put the heat on 64 daily. We wash clothes once a week and we even cut down on showers. The elec. bill was $226.00 the next month. I called my elec. company to see if my next door neighbor had elec. bills coming to her house, he said yes, but they weren’t nearly as high as mine. When I moved in my townhome/duplex, the heat was shut off from the breaker and the tenant before me had a lock on the fuse box. The heat pump is located on the inside of my townhome/duplex & there is a straight pipe running beside it. I don’t know if the next door neighbor is feeding off of my heat. There is only drywall seperating the 2 duplexes. Her elec. meter is at 18136 and mine-33300. Hers went up 100khw from last month. Can some1 help me with this?
There is no pipe running through my crawl space from the heat pump box outside, but their is wiring ran from the heat pump and a hole that is drilled in the siding of my duplex like wiring is ran through the attic?? I have no clue what’s going on.

B G asked:

I purchased a new 1,850sq ft home in August that is all electric with no heat pump. The furnace is heat pump compatible and has two 60 amp breakers for heating and blower operation. I live in Missouri and spend 300.00+ a month for electricity so far this winter. I talked to the builder and can upgrade to a heatpump for $1,000.00 since he offered to credit me for the regular A/C unit he had installed.
If I choose to do this I can also stage the heat strips for when the unit outside cannot keep up or keep them all coming on at one time to give full heat, but it would be the same as no heat pump if the heat strips were on.

I think I should be able to cut my electric bill in half or close to it unless it is extremely cold out, well I would like to. Is this a good decision and if I do upgrade to a heatpump should I have the heat strips staged for auxillary and emergency heat or just leave them all linked together?

The unit is a 13 seer 3.5 ton heatpump.
