What happens if AC BTU is too low?
If your AC is too small for the size of your home, it’ll keep working to reach that temperature, but to no avail because it lacks the capacity to cool such a large space. As a result, it never completes a cycle and runs continuously. The more heat it has, the higher BTUs required from the AC unit.
Why does my AC fan only work on high?
Your AC only working on high probably has to do with the blower motor resistor. It controls the speed of your fan and if it brakes it will only work on high. Try replacing that resistor first to see if you regain control of the fan speeds.
Why is the air coming out of my air conditioner so slow?
Air flow that is too slow for any reason (such as a dirty filter or dirty blower fan assembly blades) can cause first, air temperatures that are abnormally low coming out of the air conditioner, and eventually a reduction in air flow as coil ices over.
What happens when a heater motor resistor fails?
If the resistor shorts or fails, it may cause the blower motor to remain stuck on one fan speed. The heating and air conditioning systems may still function at one speed, however the resistor will have to be replaced in order for full functionality to be restored.
Why is my air conditioner not blowing air?
It could be an unexpectedly warm fall day or an overly wet and humid day where you just want to dry out your car or defog your windshield. Either way, when you find your air conditioner not blowing air or not turning on, it can be extremely frustrating.
Why is my car AC fan not working?
Another reason why your car AC fan is not working could be due to your cabin air filter. Cabin air filters serve as a filter to the outside air coming into your car to make sure it is clean and not filled with contaminants. However, if this air filter isn’t changed,…
What causes loss of cool air from air conditioner?
Check the ductwork for any cause of blockage, partial blockage (crimps, excessive bends), leaks, disconnects. Blocked, crimped or disconnected air ducts can also cause loss of cool air or too little cool air coming out of supply registers.

What to do if your heater is blowing cold air?
Coolant level: If your coolant level is low, your heater core may not be getting enough warmed coolant through it to produce adequate heat. Solution: Top up the coolant and see if it helps. If the level is low due to a leak, track down the source and get it repaired.
