There are too many variables in zone systems for an online diagnose. You should call a NATE certified Service Technician for service.

Yes, I believe you are correct concerning the circuit panel.

Regarding your heat pump not keeping up ...depending on what part of the country you live in, heat pumps are not the best thing to heat with. As you probably already know, once it reaches 32 degrees outside, the heat pump stops working and the electric furnace or heat strips come on to supply warm air. Frankly, when that happens, it's like turning on your kitchen toaster and blowing air across it with an electric fan. Doesn't sound to efficient does it. Plus, your electric meter is spinning like crazy and the power company is falling in love with you.

In my area (Virginia) most new home construction is now using what's called a dual fuel system. It's a heat pump, but it has a gas furnace backup for when it reaches 35 degrees outdoors. It's very, very efficient and a very comfortable heat. The gas furnace can run on either Natural Gas or Propane Gas.
In most cases this can be added to an existing heat pump system. The only thing necessary is the Gas Furnace, since you already have a heat pump and all the duct work. Could probably be added for a whole lot less than you''d expect.

The other option is to add a vent-free gas fireplace or vent-free gas logs, if you have an existing solid fuel burning fireplace. They are great for zone heating and/or supplemental heating. Plus, if you have a power outage in the middle of the winter, they'll still work, as they don't require any electricity.

I didn't mean to run own, but I hope all this helps you solve your heating problem.
Please let me know.

I have 3 coleman a/c and 2 suburban furnaces. 1 of furnaces burner cycles exessively while there is still a call for heat but blower runs normally. Could this be t-stat(coleman zoned) or limit switch?


you have multiple stages of heating and not all of the stages are operating. it could be a limit switch, that would be a very good place to start.(stages or zones)

Blank readings on Carrier Comfort 3 zone thermostat


The stat that works is called the main and the other two are called slave stats. The stats must be set to heat or cool the same as the main. If you want one room to cool and one to heat , sorry. Need to upgrade to auto changeover. Is this AC actally a Heat pump?

I'm not a fan of zoning but it sounds like they don't have the ducting done correctly. There has to be bleeder trunks installed in the unit because your are taking a unit that is designed to cool or heat a particular square footage and make it cool or heat a smaller area. This makes the unit way too big for the job you are asking it to do. If the ducting is improper, you are going to have issues like this. A lot of contractors will not admit that the ducting isn't correct due to the cost to correct it. I personally think (my opinion) that 4 zones are a little excessive. Sounds like you really need 2 units. It's hard to tell from my point of view since I'm not there to actually see what is going on. I would have a couple of different contractors come out and give you an estimate to fix the issue and then tell the installer to come and fix what they say is wrong.
