The heater valve may be damaged or stuck, or the heater control knob may be damaged.
That may be true, but do you mean to ask, "Why is the AC on with the heat?"
If the latter is your question, that is because the air conditioning drys the air better, and dry heat is more useful.
The air "conditioning", chills the temp of the air below dew point, which removes the moisture from it. Then, if you have the heater or defroster switched on, the air is then heated (if the heater is on); this is done and is advantageous because they dryer warm air will defrost the windows faster or dry your clothes if you have been caught in the rain or snow.
why does my ford focus over heat when i turn the ac on
The ac unit compressor will run when it is in defroster mode and heat setting is on.
no
Use a fan
Yes, you can replace your AC with a heat pump. Heat pumps can provide both cooling and heating functions, making them a versatile option for home climate control.
Umm yes because there is no AC........
yes, if the ac unit has 2 zones, you will need a thermostat for each zone. if the ac unit provides both ac and heat, you can connect a thermostat for each. not a good way to go. better to use 1 therm in that case that has a heat-cool switch on it so the unit is not putting out both heat and ac at the same time.
The AC runs to remove moisture from the air inside your vehicle. Moisture causes the fog inside of your windows. The ac runs to remove the moisture and the heater runs to heat the air.
The S-TV-DO-AC pattern consists of a subject (S), a transitive verb (TV), a direct object (DO), and an adverbial complement (AC). Here are five examples: The chef (S) cooked (TV) a delicious meal (DO) in the kitchen (AC). The teacher (S) assigned (TV) homework (DO) for tomorrow (AC). The dog (S) chased (TV) the ball (DO) across the yard (AC). The artist (S) painted (TV) a beautiful mural (DO) on the wall (AC). The manager (S) gave (TV) the team (DO) a new project (AC).
There are a number of reasons you can turn your AC or heat on and nothing will happen. The system may not be hooked up.
Your location matters. If in Florida heat pump in more northern climes furnace & ac.
yes but id u dont want to waste the engery open the door
