HVAC and Fan Events

Recommended Posts

We have a long, very hot summer here in Central Texas. I want to maximize cool airflow throughout my house without constantly running the AC. There is a ceiling fan in nearly every room. I'd like to time events so that the AC will run for a certain duration, turn off then turn the central HVAC fan and ceiling fans on for a duration of time.

Any ideas?

Right, but the practices I was thinking of were along the lines of running ceiling fans and the fan in the HVAC system to reduce dependency on the AC itself. I suppose if the temperature is beyond the comfort level, that means it's time to turn it on. I have two zones in my house. One for the second and third level, and one for the first level. However, the temperatures can range dynamically from one side of the house to the other even if at the thermometer it is showing a different temp.

Might be possible by checking heat/cool setpoint vs current temp, if (using cool) temp is higher then cool setpoint - start a timer.

When timer expires, set stat mode to off, turn on fan and ceiling fans, timer expires again, set tstat mode to cool, turn of fans etc.

I'd strongly suggest you test this well on-site though...

We have ours setup to cool at 74 degrees. However, when it hits 71 degrees it turns the fan on (the furnace blower) to circulate air through the house. This helps keep the house cooler longer, meaning the A/C doesn't kick on so quickly.

I have found that ceiling fans increase the comfort, but don't lower the temperature. Therefore, we turn the fans on and off as desired.

Hope that helps.

Sorry I don't get what you are describing here. Do you mean you have the fans on auto until it gets to 71 and then they are "on" all the time? Because standard forced air you're going to have to have the fan on to get cooling. I'm just probably misunderstanding you.

I have it set to heat at 69, and cool at 74, with the fan being on auto.

Every time the temp changes, if it's above or equal to 71 degrees I set the fan to ON. This turns on the blower fan in the furnace, but not the A/C units outside. It just starts circulating air through the house. Then, the A/C will kick in when it gets to 74 degrees or above.

If the temp is 70 degrees or below, I set the fan to AUTO.

Make sense?
