| Why would putting on a new thermostat make the AC not blow as hard? |
|
Please explain "not blowing as hard" as this statement is subjective.
Is the air coming out of the registers not as forceful? Is the temperature of the supply air not as cold? What thermostat did you have? What thermostat did you replace it with? What model furnace and condenser do you have? |

The only way it would do that is if you wired it incorrectly and the fan [blower] was running on the heat speed which is usually low or medium low. Do you have several different spare wires at the T stat? I don't usually have extra wires. 90% heat pumps |

Sometimes I'll put their old thermostat back on to see if it goes back and it does not. |

One time I wired a thermostat up backwards and cool air was coming from the outside unit. Was pretty freaky. Honestly, I think it's all your imagination. Replace the filter if you think sn A/C blower unit isn't blowing normally, past that, the first place I'd check is the blower motor capacitor. One that is failing but still able to get the motor moving can still have a significant decrease in motor speed. +-6% of rating. |

Cooling mode: sucks in BTU's inside coil, spits them outside Just use reversing valve to flip objects in the refrigeration process. |

Correct. Not as forceful. Sometimes the air doesn't seem as cold. Sometimes I'll put their old thermostat back on to see if it goes back and it does not. |
