1. Wiring inspection and simple repair: Disable power, then inspect the wiring of the thermostats. Take off the cover and check to see whether there are loose, corroded, or disconnected wires. All wires are connected to a labeled terminal. Common ones are: R (power), G (fan), Y (cooling), and W (heating). Loosely fitting connections should be carefully tightened, and corroded terminals cleaned with a small wire brush.

Improving Weak Airflow

1. Cleaning or replacing filters: Find your filter, typically behind a vent returning air or inside the air handler. Get it out and put it to light, and, when you find you cannot see through it easily, get another. Disposable filters are to be changed in 1-3 months.
