Last week we turned on the heater (Trane Heat Pump)it blew hot air and worked just fine. When the weather warmed back up we shut it off. Now that the winter season is arriving after turning it on, hot hair no longer comes out. What happened???
that's odd!!! Its the same thing we have been using to heat our home every winter for the last 5 years. And the air coming from it blows hot or very warm. It blew hot air a few weeks ago. Out in Arizona it is called a "heat pump". Because it switches to the a/c to blow cold air in the summer...then reverses to blow hot air to heat your home in the winter.
