Whole-house humidifiers and dehumidifiers to keep your home comfortable year-round. Professional installation, repair, and maintenance from the team North Texas trusts.
North Texas weather puts your home through extremes. Summers bring oppressive humidity that makes your AC work overtime and creates conditions for mold growth. Winters bring bone-dry air that causes static shocks, dry skin, and damage to wood floors and furniture.
At LEX Air Conditioning and Heating, we install whole-house humidity control systems that integrate directly with your HVAC system. Unlike portable units that only treat one room, our solutions maintain consistent, healthy humidity levels throughout your entire home—automatically.
Whether you need a whole-house humidifier for winter comfort, a whole-house dehumidifier for summer relief, or both, our NATE-certified technicians will assess your home and recommend the right solution.
Why Dallas-Fort Worth homes need humidity control year-round
From May through September, Dallas-Fort Worth experiences average humidity levels of 60-80%. When outdoor humidity combines with indoor moisture sources, your home can feel muggy even with AC running.
Problems caused by high humidity:
When your furnace runs during cold months, it heats air but doesn't add moisture. This drops indoor humidity to 15-25%—drier than the Sahara Desert. You'll feel it in your skin, sinuses, and energy bills.
Problems caused by low humidity:

Watch for these warning signs
Why proper humidity matters for your home and health
Reduces allergy and asthma triggers, prevents dry airways, and creates an environment where viruses spread less easily.
No more static shocks in winter or sticky, clammy summers. Balanced humidity makes your home feel comfortable at any temperature.
Protect hardwood floors, wood furniture, musical instruments, artwork, and electronics from humidity extremes.
Properly humidified air feels warmer (lower thermostat in winter). Dehumidified air cools faster (less AC runtime in summer).
Keeping humidity below 50% prevents mold and mildew growth—protecting your home's structure and your family's health.
Set your desired humidity level and forget it. Whole-house systems adjust automatically as conditions change.

Common questions about humidifiers and dehumidifiers
The ideal indoor humidity level is 30-50% relative humidity. In North Texas, summer humidity often exceeds 60-70% indoors (requiring dehumidification), while winter heating can drop indoor humidity below 20% (requiring humidification). A simple hygrometer (available for under $15) can help you monitor your home's levels.
Many Dallas-Fort Worth homes benefit from both. Dehumidifiers are typically needed during hot, humid summers (May-September) to remove excess moisture and prevent mold. Humidifiers help during winter months (November-February) when heated indoor air becomes too dry, causing static, dry skin, and respiratory discomfort.
Whole-house humidifiers connect directly to your HVAC system and plumbing, automatically maintaining consistent humidity throughout your entire home. Portable units only treat one room, require manual refilling every day or two, and need frequent cleaning to prevent mold growth. Whole-house systems are more effective, more convenient, and require less maintenance.
Signs of high humidity include: condensation on windows (especially in the morning), musty odors, visible mold or mildew growth, peeling wallpaper or paint, warped wood floors or furniture, increased allergy symptoms, and a general feeling of stickiness or clamminess indoors even with AC running.
Signs of low humidity include: excessive static electricity (shocking yourself on doorknobs), dry or itchy skin, chapped lips that won't heal, frequent nosebleeds, increased cold and flu symptoms, cracking wood furniture or hardwood floors, gaps appearing in wood trim, and feeling colder than the thermostat setting indicates.
Yes, proper humidity control can significantly reduce allergy and asthma symptoms. High humidity promotes dust mite populations, mold growth, and mildew—all common allergens. Low humidity dries out nasal passages and airways, making them more susceptible to irritation and infection. Maintaining the ideal 30-50% humidity range helps minimize both issues.
Whole-house humidifier installation typically ranges from $400-$1,200 depending on the type (bypass humidifiers are most affordable, steam humidifiers are premium). Whole-house dehumidifier installation ranges from $1,500-$3,000 depending on capacity and complexity. We provide free in-home estimates and offer financing options to make humidity control affordable.
Yes, but maintenance requirements are minimal compared to portable units. Humidifiers need their water panel or evaporator pad replaced 1-2 times per year (about $20-40 for the part). Dehumidifiers need filter cleaning every few months and an annual professional inspection. Our Cool Club maintenance plan includes humidity system checks during your regular HVAC tune-ups.
