Whole-Home Humidity Control From $600 Installed — Mabank & DFW

Your AC is a dehumidifier with a thermostat attached — but in Texas summers, especially in Cedar Creek Lake area and East Texas homes, AC alone often can't keep humidity under 60%. The result: cold, clammy rooms, condensation on registers, mold pressure in closets, and a system that runs too long trying to compensate. A whole-home dehumidifier integrated into your ductwork solves it cleanly. In winter, the opposite problem — sub-30% indoor humidity causing dry skin, sinus issues, static shocks — is solved by a whole-home humidifier. We install both across Mabank, Cedar Creek Lake Area, and the full DFW metroplex, starting at $600 installed for a winter humidifier and $1,800 for a summer dehumidifier.

Humidity Control Pricing — Honest Ranges

Fully-installed pricing across our service area:

• Whole-home humidifier (winter dry air): $600-$1,100 installed — bypass or fan-powered flow-through style, integrated into supply plenum, feeds room air at 40% RH all winter
• Steam humidifier (winter, larger homes): $1,400-$2,200 installed — higher capacity, faster response, better for homes over 3,500 sq ft or very dry-air conditions
• Whole-home dehumidifier 70-pint (summer): $1,800-$2,400 installed — standard size for 1,800-2,800 sq ft homes, removes 3-5 gallons of moisture daily in Texas summer
• Whole-home dehumidifier 90-pint: $2,400-$3,200 installed — larger homes, lake-area homes with high moisture load, removes 5-7 gallons daily
• Whole-home dehumidifier 120-pint (large homes): $3,200-$4,400 installed — over 3,500 sq ft, historic homes with poor sealing, or commercial applications
• Crawlspace dehumidifier (encapsulated space): $2,200-$3,400 installed — dedicated unit for crawlspaces where humidity migrates up into the house
• Combined humidifier + dehumidifier install: $2,200-$3,800 installed — year-round humidity control in one project, discount vs installing separately later

Prices include the equipment, integration into existing ductwork, condensate drain (for dehumidifiers), humidistat controls, and warranty registration. Free in-home assessment to confirm your specific setup.

Signs You Need a Whole-Home Dehumidifier (Summer)

• Indoor humidity above 60% even with the AC running (buy a $15 hygrometer to check)
• House feels 'cold but clammy' — you're cool but never comfortable, especially in bedrooms
• Condensation on supply registers or windows — visible moisture where air meets cold surfaces
• Persistent musty smell in closets, basements, or crawlspaces
• Mold appearing in unexpected places — behind furniture, inside closets, on ceiling corners
• AC runs constantly to try to dehumidify — high power bills and short equipment life
• You've been running portable dehumidifiers in multiple rooms — expensive and noisy, whole-home solution is cheaper long-term
• Books, leather, wood furniture warping — humidity above 65% causes measurable material damage

Signs You Need a Whole-Home Humidifier (Winter)

• Indoor humidity below 30% in winter months (again, $15 hygrometer)
• Chronic dry skin, chapped lips, cracked hands that only appear November-March
• Static electricity shocks constantly when touching doorknobs, light switches
• Sinus congestion, dry throat waking up in the morning
• Wood furniture, hardwood floors, cabinets developing gaps — wood shrinks in dry air
• Piano or acoustic guitar going out of tune constantly — instruments need 40-50% RH
• Nosebleeds in kids during winter months
• Static shocks on carpet even with anti-static laundry treatments

Why Lake-Area Homes Need This More Than Most

Cedar Creek Lake, Lake Athens, Lake Palestine, and other Trinity/East Texas watersheds have some of the highest summer humidity in the DFW region — regularly 75%+ outdoor RH from May through September. Every door opening, every shower, every cooked meal pumps moisture into the house faster than the AC alone can remove it. Even homes with brand-new high-efficiency AC systems commonly run 62-68% indoor RH in summer because the AC hits temperature setpoint before it dehumidifies enough. A 70-pint whole-home dehumidifier integrated into the return duct removes 4-6 gallons of water per day in summer here — and the AC can run less because the house isn't fighting humidity.

The Utility Bill Math — Why This Saves Money

Counterintuitively, adding a dehumidifier to your HVAC often LOWERS your total utility bill. Here's why:

• You feel comfortable at higher temperatures. At 45% humidity, most people feel comfortable at 76°F. At 65% humidity, they need 72°F to feel the same. Every 1°F higher on the thermostat saves roughly 3% on cooling costs.
• Your AC runs shorter cycles. Instead of the AC running long cycles trying to dehumidify (its secondary job), a dedicated dehumidifier handles humidity while the AC handles temperature. Both work more efficiently.
• Your AC lasts longer. Shorter cycles = less wear on the compressor and blower motor. Add 3-5 years to system life on a $9,000-$14,000 AC = $1,800-$3,500 in avoided replacement cost.
• You avoid mold remediation costs. Below 55% humidity, most mold species can't grow. Avoiding a single $2,000-$8,000 mold remediation job pays for the dehumidifier several times over.

Brands We Install — Honest Tradeoffs

• Aprilaire (Model 1830, 1850, 1870): premium brand, best-in-class reliability, 5-year warranty standard, best pick if you're staying long-term. Aprilaire also makes the most-trusted humidifier line (Models 400, 500, 600, 700, 800).
• Santa Fe (Ultra98H, Advance100): commercial-grade capacity, best for lake-area homes with severe humidity load and homes over 3,000 sq ft
• Honeywell TrueDRY: mid-tier residential, integrates well with Honeywell thermostats and controls
• GeneralAire (DH60, DH100): value tier with 5-year warranty, good pairing when budget matters more than premium features
• For humidifiers: Aprilaire dominates (Models 400 bypass, 500 fan-powered, 600 fan-powered high-capacity, 700 steam, 800 steam commercial). We install all Aprilaire models plus Honeywell HE and GeneralAire alternatives.

Installation Process — What to Expect

• Free in-home assessment — we measure your current indoor humidity across seasons, evaluate ductwork, calculate proper capacity for your home's size and moisture load
• Written flat-rate quote — equipment + labor + integration + warranty registration, signed off before any work begins
• Installation: 3-5 hours for a standard whole-home dehumidifier install, 2-4 hours for a humidifier. Includes ductwork integration, condensate drain plumbing (dehumidifiers), electrical connection, humidistat mounting
