An indoor pool room is meant to be a relaxing place. You want to be able to go for a swim, then step out of the water and dry off poolside, perhaps while chatting with friends. In order for you to enjoy your pool room in this way, its climate needs to be closely controlled. You don’t want the room to be too hot, too cold, or too humid. Indoor pool humidity control and temperature control come down to having the right equipment. Here are the key HVAC components commercial HVAC mechanical contractors typically install in indoor pool rooms.


Your pool room is a room with a huge tub of water in it, so of course, the space will tend towards being too moist. A dehumidifier is therefore essential for removing excess humidity from the air. In most cases, you should maintain the relative humidity between 50 and 60% in your pool room. This is the perfect level to prevent mold growth and other consequences of high moisture without making swimmers feel too dry and uncomfortable when they step out of the pool.

Dehumidifiers used in typical homes are not powerful enough for pool rooms. So, a commercial HVAC service company will usually install specialized dehumidifiers made just for this purpose. These dehumidifiers can remove moisture from the air rapidly, and they give you ample indoor pool room humidity control.


A large fan is important to keep the air inside your pool room moving. This ensures an even humidity throughout the space. A commercial HVAC service company will typically install a powerful, overhead fan to keep air circulating in the pool room. This fan will push warm air down, helping to maintain an even temperature all through the room.

Air Conditioner

Pool rooms are usually fitted with separate air conditioners from the rest of the home. These AC units have to work over time to remove heat that’s released from the warm pool water. A good pool room air conditioning system also pulls plenty of moisture from the air, reducing the burden on your dehumidifier.


Some pool rooms do not need heaters as the ambient heat from the heated pool is enough to keep them warm. In cold climates, however, heaters are often installed. It’s wise to have a separate heater from the rest of the home so you can keep your pool room a bit warmer than your other spaces. There are lots of smaller, easy-to-install heater options to discuss with your HVAC team.

Maintaining indoor pool air quality is so important for an enjoyable, comfortable swimming experience.
