Is the Air Inside Your Home Making You Sick?
Most Central Texas homeowners never think about what's floating in the air they breathe indoors — but the EPA estimates indoor air can be 2 to 5 times more polluted than outdoor air. In Stephenville and across Erath, Comanche, and Hamilton counties, dry summers, agricultural dust, and older home construction all compound the problem. Poor indoor air quality isn't just a comfort issue; it's a health issue.
Dust & Allergens
Windblown dust, pollen, pet dander, and mold spores accumulate in ductwork and recirculate through your living spaces every time your system runs. For allergy and asthma sufferers, this constant cycling of irritants can trigger daily symptoms.
Mold & Mildew Spores
Humid Central Texas summers create ideal conditions for mold growth inside ductwork and air handlers. Once established, mold spores spread through every room your HVAC system serves — causing musty odors and potential respiratory issues.
VOCs & Chemical Pollutants
Volatile organic compounds (VOCs) from cleaning products, paints, adhesives, and building materials off-gas into your indoor air. Without proper ventilation and purification, these invisible chemicals accumulate over time.
Carbon Dioxide & Stale Air
Tightly sealed modern homes trap CO2 and stale air without adequate fresh-air exchange. Signs include persistent fatigue, headaches, and difficulty concentrating — all common complaints in well-insulated but under-ventilated buildings.
The good news: Pro Mechanical of Texas has the equipment, training, and experience to test, diagnose, and resolve indoor air quality problems for homeowners and businesses throughout Central Texas.
Whole-Home Air Purification Systems
Standard HVAC filters trap large dust particles — but they do almost nothing against bacteria, viruses, VOCs, smoke, or ultrafine allergens. Whole-home air purification systems, installed directly into your existing ductwork, treat every cubic foot of conditioned air before it reaches your living spaces. Pro Mechanical of Texas installs, services, and maintains leading air purification systems from trusted manufacturers.
How Air Purification Differs from Filtration
Filtration physically catches particles above a certain size. Purification goes further — using technologies such as UV germicidal irradiation, photocatalytic oxidation (PCO), HEPA-grade media filtration, and bipolar ionization to neutralize pathogens, break down VOCs, and reduce airborne contaminants at a molecular level. The result is measurably cleaner air, not just filtered air.

Duct Services That Save Energy and Restore Comfort
Your ductwork is the circulatory system of your home or commercial building — and in many Central Texas properties, it's leaking, dirty, or deteriorating. The U.S. Department of Energy estimates that homes with leaky ducts lose up to 30% of conditioned air before it ever reaches a room. Pro Mechanical of Texas provides four core duct services to address every issue: cleaning, repair, replacement, and sealing.
Duct Cleaning
Over time, dust, pet dander, mold spores, and debris accumulate inside ductwork and degrade the air circulating through your home. Professional duct cleaning by Pro Mechanical uses high-powered negative-pressure equipment to extract years of buildup — reducing allergens, eliminating musty odors, and improving airflow efficiency. Recommended every 3-5 years, or sooner after renovations, pest activity, or visible mold growth.
Duct Repair
Disconnected joints, torn flex duct, collapsed sections, and punctures are common in attic-run duct systems across Stephenville and surrounding communities. Our technicians inspect, locate, and repair damaged duct sections — restoring proper airflow and preventing conditioned air from escaping into unconditioned spaces like attics and crawlspaces.
Duct Replacement
When ductwork is beyond repair — heavily corroded, crushed, or undersized for your current system — full or partial duct replacement is the right investment. Pro Mechanical designs and installs properly sized duct systems for both residential and commercial properties, ensuring your HVAC equipment operates at rated efficiency and every room receives adequate airflow.
Duct Sealing
Duct sealing addresses the small gaps, loose connections, and micro-leaks that collectively drain your energy budget and create hot or cold spots. We apply professional-grade mastic sealant and foil tape at every joint and connection point, significantly reducing air loss. Many Stephenville homeowners see lower utility bills within the first billing cycle after duct sealing.

Frequently Asked Questions: Indoor Air Quality & Duct Services
Have questions about improving your home's air quality or servicing your ductwork? Find answers to the most common questions we hear from Central Texas homeowners and business owners below.
How do I know if I have an indoor air quality problem?
Common signs include persistent allergy or asthma symptoms indoors, musty or stale odors, visible dust buildup near vents, condensation inside registers, or household members experiencing frequent headaches and fatigue with no other explanation. A professional IAQ assessment by Pro Mechanical of Texas is the most accurate way to identify specific pollutants and their concentrations in your home.Does Pro Mechanical of Texas offer air quality testing?
Yes. Our licensed technicians can perform on-site evaluations of your home's air quality and duct condition, identifying issues like mold, excessive particulate levels, and humidity imbalances. We walk you through our findings and recommend solutions sized and priced for your specific situation — no upselling, just honest recommendations.How often should residential ductwork be cleaned?
The National Air Duct Cleaners Association (NADCA) recommends cleaning residential ductwork every 3 to 5 years under normal conditions. You should consider cleaning sooner if you've recently completed a home renovation, discovered rodent or insect activity in the duct system, noticed visible mold growth near supply or return vents, or moved into a previously owned home with no documentation of prior duct cleaning.Will a whole-home air purifier help with pet dander and odors?
Yes. Whole-home air purification systems with HEPA-grade media filtration are highly effective at capturing pet dander, which is one of the most common indoor allergens. Systems that include activated carbon media or PCO (photocatalytic oxidation) technology also neutralize pet odors and VOCs — providing significantly better results than standard HVAC filters or portable room purifiers.What is duct sealing, and is it worth the cost?
Duct sealing involves applying professional-grade mastic sealant and foil tape to every joint, connection, and gap in your duct system to prevent conditioned air from escaping into unconditioned spaces. Most homes with leaky ducts lose 20-30% of their conditioned air — meaning your HVAC system works significantly harder to maintain setpoint temperatures. Duct sealing typically pays for itself through energy savings within one to three years, depending on your home's size and the severity of existing leakage.Can dirty or leaky ducts affect my HVAC system's lifespan?
Absolutely. Leaky and restricted ducts force your air handler and compressor to work harder and run longer to meet demand — accelerating wear on motors, heat exchangers, and refrigerant components. Dirty ducts also deposit debris on evaporator coils and blower wheels, reducing efficiency over time. Keeping your duct system clean and sealed is one of the most cost-effective ways to extend HVAC equipment life.Does Pro Mechanical serve commercial buildings for IAQ and duct services?
Yes. Pro Mechanical of Texas provides indoor air quality assessments, air purification system installation, and complete duct services for commercial properties including offices, retail spaces, restaurants, and industrial facilities throughout Stephenville, Comanche, Dublin, De Leon, Hico, Hamilton, and the surrounding Central Texas region.
