F & R AIR CONDITIONING | Whole-Home Dehumidifiers

The Humidity Problem Every Acadiana Homeowner Knows

You set the thermostat to 72, the house reaches 72, and it still feels sticky. The windows fog up on summer mornings. There’s a musty smell in closets that never quite goes away. Towels take forever to dry. Wood floors start cupping at the edges.

This is what uncontrolled humidity does to a South Louisiana home — and your air conditioner, no matter how new or powerful, wasn’t designed to fix it alone.

F & R Air Conditioning has been solving comfort problems in Acadiana since 1956, and humidity is the single biggest comfort complaint we hear. A whole-home dehumidifier is the most effective solution we’ve found for homes where the AC runs fine but the house still feels damp.

Why AC Alone Isn’t Enough

Your air conditioner removes humidity as a side effect of cooling. Warm air passes over the cold evaporator coil, moisture condenses, and it drains away. But this only works well when the system is running in full cooling mode for sustained periods.

The problem in South Louisiana:

Mild, humid days: when it’s 75°F outside with 95% humidity, your AC barely runs because the temperature is already close to your setpoint. But the moisture keeps coming in. These are the days when homes feel the worst.
Overnight humidity. Your AC cycles down at night when temperatures drop, but outdoor humidity actually increases after dark. Moisture infiltrates while your system sleeps.
Oversized systems, an AC that’s too large for the space cools quickly but shuts off before it has time to pull meaningful moisture from the air. This is common in homes where the original system was oversized or a replacement was upsized unnecessarily.
Ventilation and infiltration. Every time a door opens, every gap around a window or pipe penetration, humidity enters. In our climate, the sheer volume of moisture in the outdoor air overwhelms a home’s defenses.

How a Whole-Home Dehumidifier Works

A whole-home dehumidifier installs into your existing ductwork and drain system. It operates independently from your air conditioner, running whenever indoor humidity rises above your target setpoint — regardless of whether the AC is calling for cooling.

Continuous moisture control: it works on those mild, damp days when the AC isn’t running, on humid nights, and during the shoulder seasons when temperatures are comfortable but moisture is not.
Set-and-forget operation. You choose a target humidity level (typically 50-55%), and the unit manages it automatically. No portable units to empty, no buckets to dump.
Works with your HVAC system, it uses your home’s existing duct system to circulate air through the dehumidifier, treating every room in the house rather than just one area.
Handles serious moisture loads: whole-home units can remove 70 to 100+ pints of moisture per day, compared to 30-40 pints for a good portable unit. In South Louisiana, you need that capacity.

Signs Your Home Needs a Dehumidifier

Condensation on windows, especially in the morning
Musty or damp odors in closets, bathrooms, or rarely used rooms
Mold growth on walls, ceilings, or around AC vents
Wood floors that buckle, cup, or feel soft
Peeling paint or wallpaper
The AC runs fine but the house still feels clammy
A hygrometer consistently reads above 60% indoors

Brands We Install

We install ENERGY STAR-rated whole-home dehumidifiers from Lennox®, Aprilaire, and Santa Fe, all designed for integration with forced-air HVAC systems. We’ll recommend the right unit based on your home’s square footage, construction type, and the severity of your humidity issues.

Protect Your Home, Not Just Your Comfort

The EPA recommends keeping indoor humidity between 30% and 50% to minimize health risks and structural damage. Uncontrolled humidity isn’t just uncomfortable — it damages your home. Mold remediation costs thousands. Wood rot compromises structural integrity. Electronics corrode. HVAC equipment works harder and fails sooner. A whole-home dehumidifier is a fraction of the cost of dealing with the consequences of letting humidity go unchecked.

F & R has been helping Acadiana families breathe easier since 1956. If your home feels damp even with the AC running, contact us for a humidity evaluation. We’ll measure your indoor levels, assess your home’s specific moisture challenges, and recommend the right solution, whether that’s a dehumidifier, improved air sealing, or both.

Frequently Asked Questions

Can't my air conditioner handle humidity?

It removes some moisture as a byproduct of cooling, but it wasn't designed to be a dehumidifier. In South Louisiana, where outdoor humidity regularly exceeds 90%, your AC can't keep indoor levels below the 50-60% range on its own, especially on mild, damp days when it doesn't run long enough to pull much moisture.

What humidity level should my home be at?

Between 40% and 55% is the target range. Below 40% feels dry and can cause static and cracking wood. Above 60% creates conditions for mold growth, dust mites, and that sticky, clammy feeling that's all too familiar in Acadiana.

How much does a whole-home dehumidifier cost to install?

Installed cost varies depending on your home's size and the unit capacity needed. We provide a written quote after evaluating your home. Financing is available. Most homeowners see the investment pay for itself through reduced HVAC strain and avoided mold remediation.

Where does the dehumidifier get installed?

It connects to your existing ductwork and drain system, typically near your air handler in the attic, closet, or garage. It works automatically alongside your HVAC system. You set your target humidity and forget about it.

Will a dehumidifier lower my energy bills?

It can. When indoor humidity is controlled, you can set your thermostat a degree or two higher and still feel comfortable, because dry air feels cooler. Your AC also runs more efficiently when it's not fighting excess moisture, which reduces overall energy consumption.
