HVAC runs constantly

RK6 — Fri, 12 Jan 2024 14:25:45 GMT

The HVAC runs too long. New to nest in a new(open about a year) apartment building with nests in every apartment. When I set a new temperature, the display tells me how long it will take to reach that temp. In the most recent attempt to lower the temp ONE DEGREE (from 73° to 72°), the display says "IN 2+ HR". That's just crazy. I can't afford to pay a utility bill when the unit is constantly running. Any suggestions?

And, by the way, the first thing I did was have the thermostat replaced, which they did. But the replacement behaves just like the original. I can't find a model # or serial # to guide you.

Hello RK6,

Thank you for reaching out and sharing your concerns about the HVAC system in your apartment building, equipped with Nest Thermostats. We understand the importance of a comfortable living environment and the impact it can have on utility bills.

I appreciate that you've taken the initiative to have the thermostat replaced, but it seems like the issue persists despite the replacement. Here are a few suggestions to address the issue:

Instead of making drastic one-degree changes, try adjusting the temperature gradually. This may help the system operate more efficiently and reach the desired temperature in a shorter time.
Ensure that your apartment is well-insulated. Poor insulation can lead to heat loss, making the HVAC system work harder to maintain the desired temperature.
Please check out this article to learn about the common or C wire article. It would help your thermostat deliver constant power.

Let us know if you have more questions.

Best regards,
Mark
