I have replaced my entire Central Air system in my house. I had the Conderser and the Furnace replaced. <-Actually, I hired a professional (business) to do this.
How long (how many hours) do I need to keep my system running / blowing only the air to "train" it to my house? My house size is 1,300 square feet (living space.) I hear recommendations from 48 / 24 / 12 hours duration to help the system to acclimate to its setting.
In the ongoing HEAT, I am desperate to start cooling the air inside before I need to use the heater. Local weather is known to immediately-change. The saying "if you don't like the regional weather, wait ten minutes, it'll change!" is True!
