Why Four Corners Homes Are Different

Four Corners sits in Fort Bend County’s rapid-growth corridor, built almost entirely during the 2000s-2010s boom. The housing stock is nearly universal slab-on-grade tract homes with builder-grade flex duct routed through unconditioned attics. At 10-20 years old, these systems sag at joints, trap debris, and lose airflow capacity.

The Houston-metro climate compounds every problem. Attic temperatures exceed 140°F in summer, outdoor relative humidity stays above 75% for months, and AC systems run 8-9 months straight. That continuous operation pulls allergens through aging duct lining with no seasonal break to slow buildup.

Then there’s Hurricane Harvey. In August 2017, floodwater and severe moisture penetrated homes across lower-lying Fort Bend County areas. Surface remediation happened; ductwork inspection rarely did. We still find active mold colonies inside flex duct systems that were declared dry years ago.

Our Main Four Corners Services

Three services have dedicated Four Corners pages with full pricing and scope details:

Air Duct Cleaning in Four Corners

We clean the full duct network in Four Corners homes using negative-pressure extraction, photographing every run before and after. The builder-grade flex duct common here traps debris at sag points and separated joints that rigid metal would not. Our crews know where to look. Air Duct Cleaning in Four Corners covers full scope and pricing.

Dryer Vent Cleaning in Four Corners

Dryer vent blockages in Four Corners often involve lint packed at the attic transition where flex duct sags. We clean the full run from appliance to termination, photograph the obstruction, and verify airflow with a manometer. Dryer Vent Cleaning in Four Corners has full details.

Duct Repair & Sealing in Four Corners

Separated joints, crushed flex sections, and failed tape seals are standard finds in 15-year-old Four Corners ductwork. We repair with mechanical fasteners and mastic, then pressure-test. Duct Repair & Sealing in Four Corners explains our repair scope.

Before

After

HVAC Cleaning in Four Corners

Four Corners HVAC systems run harder and longer than equipment in most U.S. markets, pulling continuous airflow through flex duct that sheds lining debris directly onto coils and blowers. The result is restricted airflow, frozen evaporator coils, and blower motors laboring against buildup that standard filter changes never reach. Our HVAC Cleaning service treats the full air path, not just the ducts.

Evaporator Coil Cleaning

Signs you need it

Ice on the coil, weak airflow from registers, or AC running constantly without reaching setpoint.

What it costs in Four Corners

Evaporator coil cleaning in Four Corners typically ranges $180-$320.

How we do it

We access the coil through the plenum, apply foaming cleaner, rinse with low-pressure water, and photograph before and after through the access panel.

Blower Cleaning

Signs you need it

Unusual blower noise, vibration, or dust puffing from registers when the system cycles on.

What it costs in Four Corners

Blower assembly cleaning in Four Corners typically ranges $160-$280.

How we do it

We remove the blower housing, clean the wheel and motor housing with compressed air and solvent, balance the assembly, and document with photos.

What HVAC Cleaning Costs in Four Corners

How do I know my HVAC needs cleaning, not just my ducts?

If your registers blow weak or warm air despite clean ducts, or your AC ices up repeatedly, the restriction is likely at the coil or blower. We inspect both during every duct cleaning and report what the camera shows.

Can HVAC cleaning fix my high summer electric bills in Four Corners?

Dirty coils and blowers force the system to run longer to move the same air; cleaning restores design airflow and can reduce runtime. Call (346) 666-7165 and we’ll measure your static pressure to show where the restriction is.

Air Quality & Sanitizing in Four Corners

Four Corners homes harbor a specific air quality risk: flex duct systems that took moisture during Hurricane Harvey and now carry latent mold loads that standard HVAC service never addresses. The subtropical humidity keeps these colonies active year-round, cycling spores through living spaces every time the AC runs. Our Air Quality & Sanitizing service targets biological contamination with documented treatment, not masking agents.

Mold Treatment

Signs you need it

Musty odor when AC cycles, visible mold at registers, or respiratory symptoms that worsen at home.

What it costs in Four Corners

Mold treatment for duct systems in Four Corners typically ranges $280-$520.

How we do it

We apply EPA-registered antimicrobial through the full duct network, treat the plenum and coil pan, and deliver before-and-after photos of the treated surfaces.

UV Light Installation

Signs you need it

Repeated mold recurrence after cleaning, or chronic moisture in the air handler from Four Corners humidity.

What it costs in Four Corners

UV-C light installation in Four Corners typically ranges $320-$580.

How we do it

We mount a UV-C lamp in the supply plenum, wire to the blower circuit for automatic operation, and verify irradiance with a meter.

What Air Quality & Sanitizing Costs in Four Corners

Is mold in my ducts from Hurricane Harvey or just normal humidity?

Both contribute, but Harvey-affected homes in lower Four Corners areas show distinct patterns: mold concentrated at low points where floodwater pooled in duct runs, not uniform surface growth. Our camera inspection shows which pattern yours follows.

Will UV light actually prevent mold in Four Corners humidity?

UV-C at proper irradiance prevents mold colonization on irradiated surfaces; it does not dehumidify. We pair UV installation with coil and pan treatment to address both the biological and moisture vectors.
