AC question........too humid

Don't have any excess :o)

Nick,

Too Low is less than 350 CFM per ton for most manufacturers. Lennox says you can go as low as 300 CFM/ ton with their equipment.

You say it sounds too high. Many things can cause tigh humidity in the space.

• Continuous blower operation

• Oversized AC equipment

• Duct leakage

• Excessive air infiltration

• Improper refrigerant charge

• Short cycling (See oversized AC, above)

• Excessive exhaust fan use with high outside humidity.

• Interior water sources such as too many plants

• Dryer vent leaking to indoor space

• Unvented combustion appliances

• Etc.

The thing to do is actually MEASURE the conditrions. Sitting in an ivory tower and guessing is not the solution.

Nick,

The increase in the electric bill depends on how efficient the dehumidifier is. Some are quite efficient, especially those with heat recovery built in.
