Sticky summer air is a fact of life in Weston. When outdoor humidity creeps in, your home can feel warmer, your A/C works harder, and finishes like wood floors and cabinets can suffer. If you are living here or planning to sell soon, smart humidity control protects your comfort and your home’s value. In this guide, you will learn how to use your A/C more effectively, when to add whole‑home dehumidification, and the simple maintenance steps that keep humidity in check. Let’s dive in.
Why Weston homes trap humidity
Weston sits in South Florida’s hot, humid climate. During the wet season, roughly June through September, relative humidity stays high day and night. Hurricane season, June through November, adds moisture risks from storms and possible power outages. Homes face a persistent moisture load for much of the year.
High indoor humidity does more than feel uncomfortable. Sustained indoor relative humidity above about 60 percent increases the risk of mold and dust mites. That can trigger allergies or asthma for sensitive people. It can also lead to condensation on windows, warping of wood, peeling paint, and corrosion of mechanical parts. Your A/C may run longer and still remove less moisture if the system is oversized or short cycles.
What humidity level to aim for
For most Weston homes, aim for 40 to 50 percent RH during the cooling season. Avoid sustained indoor RH above 60 percent. Lower targets than 40 percent are not usually needed and can cause dryness in wood finishes. Use a reliable hygrometer to track indoor RH and watch how it changes during rain, evenings, and mild nights.
Use your A/C smarter
Choose the right system features
Your central A/C is the first line of defense because cold coils remove moisture as air passes over them. Certain features improve dehumidification:
- Variable‑speed or multi‑stage compressors run longer at lower speeds, which removes more moisture than short on‑off cycles.
- Proper sizing matters. Oversized systems cool fast, shut off, and do less moisture removal. Slightly longer runtimes help with humidity control.
- Clean coils and correct refrigerant charge improve latent removal. Dirty coils and low charge reduce performance.
- Some systems and thermostats offer a dehumidify or humidity hold mode that adjusts how the compressor and fan operate to prioritize moisture removal.
Thermostat settings that help
- Set the fan to Auto, not On. Auto lets condensed moisture drain off coils between cycles. Fan On can re‑evaporate water on the coil and raise indoor RH.
- Use a temperature setpoint you can maintain without overcooling. Many homes start around 76 to 78°F while occupied, then adjust based on comfort and RH. The goal is steady runtime that helps remove moisture.
- If your thermostat allows, use a humidity setpoint, such as “keep RH at or below 50 percent.” This avoids dropping the temperature too low just to dry the air.
Limits of A/C alone
In very humid weather, a typical single‑stage system may struggle to keep RH near 50 percent without uncomfortable overcooling. On mild nights, the system may not run enough to remove moisture even if the temperature feels fine. After a storm or power outage, indoor RH can rise quickly. These conditions are common in Weston, which is why many homes add dedicated dehumidification.
When to add dehumidification
Options that work
- Whole‑house dehumidifiers tie into your duct system and remove moisture across the home. They drain condensate to plumbing or a pump and are sized by pints per day.
- Integrated manufacturer modules can communicate with your air handler and thermostat to coordinate cooling and dehumidifying.
- Portable dehumidifiers help in specific rooms, garages, or problem spots, but they are noisier and less convenient for whole‑home control.
- Crawlspace dehumidifiers are designed for enclosed areas under the home and can reduce moisture exchange into living spaces.
Sizing and placement
Capacity depends on your home’s size, how tight the building envelope is, and outdoor conditions. In hot, very humid climates, whole‑house units commonly range from about 30 to more than 100 pints per day. A qualified HVAC contractor should calculate your latent load and recommend the right size. Typical placements include the equipment room or return plenum, with clear access for service and dependable drainage.
Controls, drainage, and energy use
For best results, integrate controls so your dehumidifier and A/C do not work at cross‑purposes. Use a humidity setpoint and priority modes when available. Make sure condensate drains properly to a gravity drain, pump, or code‑approved plumbing connection. Expect added electricity use, although whole‑house units are usually more efficient per pint than many portable units. The right system often reduces A/C runtime and improves comfort, which can balance energy use.
Smart monitoring and maintenance
Track humidity like a pro
Place at least one reliable hygrometer in a main living area, away from supply vents and windows. Many smart thermostats include humidity sensors and mobile alerts. If your system allows, automate humidity setpoints, nighttime dehumidifier cycles, and fan control to match Weston’s rainy days and muggy evenings.
Maintenance that matters
- Change HVAC filters every 1 to 3 months based on use. Clean filters maintain airflow and coil performance.
- Keep evaporator coils, condensate pans, and drains clean and clear. This reduces overflow and microbial growth.
- Have refrigerant charge and airflow checked. Low charge or poor airflow reduces dehumidification.
- Inspect and seal ductwork. Leaky or uninsulated ducts can pull in humid air and sweat in warm spaces.
- Schedule annual professional tune‑ups before peak cooling. Preventive service preserves comfort and efficiency.
Tighten the envelope and habits
Seal gaps at windows, doors, and wall penetrations to reduce humid air infiltration. Use bathroom and kitchen exhaust fans during moisture‑producing activities, and operate them in a controlled way to avoid drawing in outdoor humidity continuously. Maintain attic insulation and ventilation as recommended. If you have an enclosed crawlspace, ensure a ground vapor barrier and consider a crawlspace dehumidifier when needed.
Seller checklist before listing
If you plan to sell in Weston, humidity control should be part of your pre‑listing prep. Buyers often notice musty odors, window condensation, or visible mold, and inspectors flag high indoor RH and poor dehumidification.
- Address active moisture and visible mold before you list. Known moisture and mold issues are typically subject to disclosure in Florida. Consult your Realtor and, when needed, a real estate attorney.
- Gather documentation. HVAC service records, recent tune‑ups, dehumidifier installation receipts, and smart thermostat logs that show stable RH reassure buyers.
- Present a clear plan. If your home has persistent humidity, consider installing a whole‑home dehumidifier or upgrading to variable‑speed equipment. This can reduce objections and support stronger offers.
Local permits and incentives
Major HVAC changes and some condensate plumbing connections may require permits in Broward County or the City of Weston. Your licensed contractor should pull the correct permits. Local utilities, such as Florida Power & Light, sometimes offer rebates for high‑efficiency equipment or qualifying upgrades. Programs change often, so check current offerings before you invest.
Quick Weston checklist
- Monitor indoor RH and target 40 to 50 percent.
- Set your thermostat fan to Auto, and avoid continuous fan On.
- Start around 76 to 78°F while home, then fine‑tune for comfort and RH.
- Schedule annual HVAC maintenance, and keep coils and condensate lines clean.
- Seal air leaks, and verify attic insulation and duct sealing.
- If indoor RH stays above about 55 percent, talk with a qualified HVAC contractor about whole‑home dehumidification or a variable‑speed upgrade.

FAQs
What indoor humidity is best for Weston homes?
- Aim for 40 to 50 percent relative humidity during the cooling season, and avoid sustained levels above 60 percent.
Can lowering the thermostat fix high humidity?
- Lowering temperature can help some, but it is often inefficient and not reliable with single‑stage systems. Longer, steadier runtimes or a dedicated dehumidifier works better.
Should I use the A/C fan On or Auto for humidity?
- Use Auto. Fan On can re‑evaporate moisture from the coil and raise indoor humidity.
Do ERVs or HRVs help in Weston’s climate?
- These systems can introduce humidity if not carefully selected and controlled. Focus first on dedicated dehumidification and ventilation strategies designed for humid climates.
Are whole‑house dehumidifiers noisy?
- Properly installed ducted units are usually quieter in living areas than portable units, since the equipment sits in a utility space and connects to ducts.
How often should I service a whole‑house dehumidifier?
- Plan seasonal checkups and annual servicing to clean coils, verify drainage, and confirm controls. Replace filters on the manufacturer’s schedule.
