Air Duct Cleaning in Fresno - One Flat Price, Before-and-After Photos

Air Duct Cleaning in Fresno, TX

HVAC cleaning in Fresno typically runs $350-$650 for a complete system, and every job starts with a written price before we touch a single panel. In this Fort Bend County suburb, where most homes were built during the 2000s and 2010s housing boom, thousands of flex-duct systems are now reaching the age where debris accumulation and microbial growth become measurable problems, not theories. We dispatch crews from our Houston office and serve Fresno homeowners with the same documented process we’ve used since 2013: written price first, photo record of every duct run, and the 365-Day Done Right Promise backed in writing.

Why Fresno Homes Are Different

Fresno’s housing stock is almost entirely tract homes built between 2002 and 2018, constructed to Houston-metro standards with flex duct routed through unconditioned attics. Those attics routinely exceed 140°F from June through September, accelerating the breakdown of duct liner adhesive and the accumulation of settled debris. The extreme humidity belt here, with dew points above 70°F for nearly half the year, creates a specific mechanical problem: when AC short-cycles or a duct seal fails, warm humid air contacts the cool duct surface and condenses. That moisture seeds mold colonies inside the plenum, the main trunk, and the individual duct runs.

Builders in Fresno’s newer subdivisions commonly used minimal support hangers to cut costs. After a decade-plus of thermal cycling, those flex ducts sag, kink, and partially collapse. A technician working in Fresno should always inspect for crushed flex runs, because a clean but kinked duct still chokes airflow and wastes energy. This combination of housing age, attic heat, and humidity load makes duct cleaning here a health-driven and efficiency-driven service, not optional maintenance.

Our Main Fresno Services

Most Fresno homeowners who call us need one of these three services. Each has its own dedicated Fresno page with deeper detail on local conditions and pricing.

Air Duct Cleaning in Fresno

We clean the full supply and return network, from the plenum (the distribution box at your air handler) through every duct run to each register. In Fresno, we regularly find 2-4 inches of debris buildup at the first elbow past the plenum, plus sagging flex that traps material in low spots. Every run is photographed before and after, and the photo record is delivered as part of the standard job file. Air Duct Cleaning in Fresno covers complete pricing and what the process looks like in local homes.

Dryer Vent Cleaning in Fresno

Lint accumulation in dryer vents is accelerated in Fresno’s humidity, where moisture binds lint to duct walls more aggressively than in dry climates. We use negative-pressure extraction with rotary brushes to clear the full vent path, terminating at the exterior hood. The job includes airflow measurement before and after. Dryer Vent Cleaning in Fresno has full details on fire-risk signs and what the service costs.

Duct Repair & Sealing in Fresno

Given the flex-duct support problems common in Fresno’s 2000s-era subdivisions, we regularly repair crushed runs, replace failed support straps, and seal leaks at plenum connections with mastic and metal tape. Sealing alone can recover 20-30% of conditioned air lost to attic leaks. Duct Repair & Sealing in Fresno explains how we diagnose and fix these specific local failures.

HVAC Cleaning in Fresno

Complete HVAC cleaning addresses the components air actually passes through: the evaporator coil, blower assembly, condenser, and air handler. In Fresno, where systems run heavily from March through November and flex-duct debris circulates back to the air handler, these components foul faster than in drier climates. The same humidity that seeds mold in ducts also coats coils with a biofilm that reduces heat transfer and raises energy bills. We include HVAC Cleaning as a core service because component cleaning without duct cleaning, or vice versa, leaves the contamination source intact.

Evaporator Coil Cleaning

Signs you need it

Ice formation on the coil, reduced airflow from registers, or a musty odor when the AC cycles on.

What it costs in Fresno

Evaporator coil cleaning typically runs $180-$320.

How we do it

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

Blower Cleaning

Signs you need it

Vibration or noise from the air handler, uneven airflow room to room, or dust streaking from supply registers.

What it costs in Fresno

Blower assembly cleaning typically runs $150-$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 Fresno

How do I know my HVAC components are actually dirty?

We photograph every component before touching it, and you receive those images as part of the standard job record. If the coil shows no measurable fouling, we’ll tell you before quoting any work.

Can HVAC cleaning lower my electric bill in Fresno?

Yes, a fouled evaporator coil can raise cooling costs 15-25% by reducing heat transfer efficiency. In Fresno’s eight-month cooling season, that adds up fast. Call (346) 253-1822 for a free estimate.

Air Quality & Sanitizing in Fresno

Air quality and sanitizing services target the biological load inside duct systems: mold colonies, bacterial biofilms, and the persistent odors they produce. In Fresno’s humidity-driven climate, where condensation inside ducts is a recurring mechanical reality, these treatments are often necessary follow-ups to cleaning, not optional add-ons. We use Air Quality & Sanitizing protocols developed for Gulf Coast conditions, with products rated for occupied-space application and documentation of treatment coverage.

Mold Treatment

Signs you need it

Visible mold at registers, a persistent earthy odor when the system runs, or recent water intrusion into the duct system.

What it costs in Fresno

Mold treatment typically runs $250-$450 per system.

How we do it

We apply an EPA-registered antimicrobial to all interior duct surfaces using fogging equipment, with dwell time verified and post-treatment photos of representative runs.

UV Light Installation

Signs you need it

Recurring mold despite cleaning, allergy symptoms that worsen when the AC runs, or a system located in a damp crawlspace or closet.

What it costs in Fresno

UV light installation typically runs $300-$550.

How we do it

We mount a UV-C lamp in the supply plenum, wire to the air handler’s 24V circuit, and verify irradiance at the coil surface with a meter.

What Air Quality & Sanitizing Costs in Fresno

Is mold treatment safe to run with my family home?

Yes, we use products rated for occupied-space application with no re-entry delay, and we document the product name and EPA registration number on your job record for verification.

Will UV lights actually prevent mold in Fresno’s humidity?

UV-C at the coil surface prevents the biofilm buildup that mold feeds on; in Fresno’s conditions, it’s the most effective long-term control when combined with proper duct sealing. Call (346) 253-1822 for a free estimate.
