Heating and Air Conditioning questions, answered by experts

When first installed, flex ducts shouldn’t cause airflow problems in your home. However, because flex ducts aren’t the sturdiest and require extra support, they lose their durability over time and begin to sag, which can inhibit airflow down the road. Also, if your flex ducts aren’t tight enough, your HVAC could work twice as hard for the same air pressure. If you’re worried about the airflow in your home, a rigid duct may be your best bet.

As mentioned above, not all HVAC Schrader valves are necessarily the same. While the valve core and pin or spring size on Schrader valves used for HVAC are generally similar, the valves are not all universal and interchangeable. The size of Schrader valves varies depending on whether it's used in an air conditioner, bicycle tire, or motor vehicle tire.

Unfreezing an AC unit is not a DIY project unless the problem is a dirty air filter. Changing out an air filter is easy for homeowners, but otherwise, trying to repair ductwork, refill refrigerant, or replace a blower fan motor are tasks best left to the pros. Otherwise, you could cause further damage to your cooling system or even harm to yourself.

Replacing an HVAC system does not always include new ductwork. The decision depends on the condition of your existing ducts. If they are in good shape, correctly sized for the new unit, and meet current standards, they can often be reused. However, if the ducts are damaged, poorly designed, or improperly sized, they will likely need to be replaced or upgraded to ensure the new system operates efficiently. An HVAC contractor will assess your ductwork and recommend the best course of action. Typically, ductwork is purchased separately, and a full replacement will add to the overall project cost.

While personal preferences widely vary, sleep experts say the best temperature for sleeping is between 60 and 67 degrees Fahrenheit rather than 78. If you do choose to sleep with your AC unit tuned to 78 degrees, you might want to use only a sheet or light blanket rather than a comforter. You might also consider installing a window unit in your bedroom so that you can be cooler in bed without wasting energy cooling the whole house.
