Hvac acting weird

[Vicso1208]

Hi everyone. I just moved into a new home a few months ago. A/c had been working great until a few days ago. Everytime I put on the a/c my heat kicks in at the same time. I do have zoned thermostats in the home. They are not digital. Can someone give me any tips where to get started with this?

If you have a zoned system, I would call a professional.

Even the most skilled tech can be stumped by zoning.

Call a serviceman to check control wiring.

Thanks for the help. I was planing on changing the thermostats tomorrow but I'll wait. Calling someone instead.

Make sure t-stats are set in cooling mode, which you might already have, then you could try turning one zone t-stat off, and turn the other one on and see if you still have the problem, could be just one zone with issues, or could be more to it , in that case you'll need to call for service.
