What’s the Cost of a Whole‑Home Dehumidifier in Florida?

Looking for ways to improve your indoor air quality and help with allergies? Get year-round comfort by adding a whole-home dehumidifier to your AC system.

In Florida, the cost of purchasing and installing a whole-home dehumidifier is about $4,500.

The cost depends on several key factors, including:

  1. Capacity of the unit

  2. Gravity-fed v.s. pump drainage unit

  3. Installation considerations

  4. The contractor you hire

Many Florida residents run a dehumidifier in place of their AC during the off-season when temperatures are cooler, but humidity needs to be controlled. A dehumidifier may also help reduce monthly energy bills too.

To better understand the overall cost, we’ll take a look at each factor below.

Cost Factor #1: Capacity of the unit

Whole-home dehumidifiers are sold by capacity. Meaning, how many pints of moisture they can remove from your air in a 24-hour period.

In general, the more moisture a unit can remove, the more expensive it will be to purchase and install.

To determine the capacity of dehumidifier you need for your home, it’s important to consider the following:

1. Square footage

If you have a large home, you can expect to pay more for a high-capacity unit.

For example, a 2,500 square foot home in Florida will produce about 44 pints of moisture in 24 hours on average. In contrast, a 3,800 square foot home will produce about 70 pints of moisture during the same time period.

Because the larger home produces almost twice as much moisture, it will require a higher capacity to handle it.

2. Climate

If you live in a humid climate like Florida, you’ll have higher indoor moisture levels than you would in a drier climate. For this reason, depending on your home’s location, you may need to pay more for a higher capacity dehumidifier.

Cost Factor #2: Gravity-fed v.s. pump drainage unit

Once moisture is removed from the air, it has to be drained somewhere. How that water is drained can impact the cost you pay for the dehumidifier purchase and installation.

Most whole-home dehumidifiers remove moisture in one of two ways:

1. Gravity fed - Less expensive

As the name suggests, gravity-fed units use the force of gravity to drain moisture through a tube to the outside of your home. Because they don’t require any extensive setup, they are typically less expensive.

2. Pump - More expensive

If your dehumidifier is located below ground, such as in a basement or area where it has to fight gravity to drain the water outside, you may need a pump to assist it. Some pumps push the excess fluid up, while other pumps suction the water out. In either case, the cost of the pump and setup will impact the price of installation.

Cost Factor #3: Installation considerations

Several installation factors will impact the cost of your dehumidifier setup:

1. HVAC repairs

Whole-home dehumidifiers are installed in conjunction with a home’s HVAC system. Because an air conditioner is designed to remove indoor humidity too, your AC should be in good operational condition before the dehumidifier unit is installed. If not, the new unit will have to overcompensate to remove excess humidity from your home, which could eventually cause an AC system breakdown.

It’s best to repair the AC system first, which will increase the cost of the dehumidifier installation. But, in the long run, having a properly working HVAC system is more cost-effective and energy-efficient and also helps your new humidifier perform at a high-level too.

2. Electrical outlet setup

Certain kinds of electrical outlets can be required for your dehumidifier. If you don’t have the righttype of outlet nearby, you may have to install it, which can increase your costs.

3. Adding a return duct

Some dehumidifiers require their own dedicated return vent to suction out the air to be dehumidified. If you need to install a vent, there may be additional cost for the extra labor and materials.

Cost Factor #4: The contractor you hire

As with most home repairs, the more experienced your contractor is, the more they may charge for their work.

However, that shouldn't prevent you from using an experienced contractor. A dehumidifier can improve the quality of the air you breathe and enhance your lifestyle, so it’s best to choose a contractor who knows what they’re doing.

When searching for a trustworthy contractor, look for the following:

  • Proof of licensing and insurance

  • 10+ years of experience

  • Positive reviews from recent customers

  • Free, up-front estimates

  • Written estimate detailing the work to be completed

Set your home up for success, and choose a contractor who can deliver true comfort and liveability.
