With computer-aided design (CAD) and Manual D/S/T calculations, HEP verifies that duct sizing, grille placement, and fan selection maintain optimal velocity and static pressure while avoiding noise or drafts.
Core Ventilation Services Offered by HEP Company in Hixson
Air Duct Installation and Replacement
Poorly sized or deteriorating ductwork is a leading contributor to uneven temperatures and elevated energy bills. HEP Company fabricates and installs:
- Rigid sheet-metal trunks and branches for longevity and minimal leakage
- Flexible duct runs with smooth interior linings for tight spaces
- Insulated plenums to prevent condensation in Hixson’s humid summers
When replacing aging ducts, technicians remove compromised materials, seal connections with mastic or UL-listed tape, and test for leakage rates that meet or exceed ACCA standards.
Air Duct Cleaning and Sanitizing
Dust, pollen, pet dander, and microbial colonies gradually coat duct interiors, circulating irritants with every HVAC cycle. HEP’s multi-stage cleaning process includes:
- Negative-pressure containment using high-powered HEPA vacuums
- Mechanical agitation via rotary brushes to dislodge debris
- Targeted application of EPA-registered disinfectants
- Post-cleaning verification with borescope imaging
This rigorous protocol restores free airflow, lowers allergen loads, and prolongs blower motor life.
Exhaust and Supply Fan Configuration
From commercial kitchens venting grease-laden vapors to residential bathrooms combating high humidity, proper fan selection and placement are crucial. HEP technicians:
- Calculate required cubic feet per minute (CFM) based on room volume and usage
- Install backdraft dampers to prevent outdoor air infiltration
- Balance exhaust and supply flows to maintain neutral pressure
Balanced pressure avoids pulling unconditioned outdoor air through wall cavities, thereby preventing energy loss and moisture infiltration.
Energy Recovery and Heat Recovery Ventilators
Energy Recovery Ventilators (ERVs) and Heat Recovery Ventilators (HRVs) exchange stale indoor air with fresh outdoor air while capturing a significant portion of thermal energy. HEP selects the right technology based on Hixson’s temperature and humidity swings:
- ERVs excel during muggy summers by moderating humidity transfer
- HRVs shine in cooler months by conserving sensible heat
Integrated with existing HVAC systems, these units supply conditioned fresh air with minimal additional load on heating or cooling equipment.
Attic and Crawl Space Ventilation Enhancements
Attics can reach extreme temperatures in July and August, while crawl spaces often harbor damp, stagnant air year-round. HEP remedies these hidden problem zones with:
- Ridge and soffit vent installation for continuous attic airflow
- Solar-powered or thermostatically controlled attic fans
- Crawl space encapsulation with vapor barriers and dehumidification units
By controlling moisture and excessive heat at the building envelope’s extremities, the interior HVAC system works under far less strain.
Indoor Air Quality Technologies Deployed by HEP Technicians
High-Efficiency Air Filtration
Standard one-inch fiberglass filters trap only a fraction of airborne particles. HEP upgrades clients to:
- Pleated media filters with MERV ratings of 11–16
- Deep-pleat box filters that extend service intervals
- Custom filter cabinets with airtight gaskets to eliminate bypass
Higher-efficiency filtration captures pollen, pet dander, and fine dust without choking airflow when sized correctly.
Ultraviolet Germicidal Irradiation (UVGI)
UV lamps installed in air handlers or ducts neutralize microbial contaminants as air flows past. HEP uses germicidal-grade UV-C wavelengths to:
- Inactivate mold spores on coil surfaces
- Destroy bacteria and viruses within the airstream
- Reduce biofilm buildup that can impede heat exchange
UVGI complements mechanical filtration by targeting pathogens too small to be effectively trapped by media alone.
Whole-Home Humidifiers and Dehumidifiers
Indoor humidity outside the ideal 40–60 percent range contributes to respiratory irritation, static electricity, and structural damage. HEP integrates:
- Steam or evaporative humidifiers for dry winter conditions
- Whole-home dehumidifiers capable of removing pints of moisture daily in summer
- Hygrostats tied into smart thermostats for automatic modulation
Proper humidity control also reduces the presence of dust mites and mold, enhancing overall IAQ.
Electronic Air Cleaners and Ionizers
Electronic air cleaners charge particles so they cluster and become easier to trap, while ionizers release ions that neutralize airborne contaminants. HEP evaluates:
- Ozone-free ionization technologies to ensure occupant safety
- Electronic cells sized for total system airflow
- Washable cells to lower maintenance costs over disposable filters
When combined with mechanical filtration, these devices add a final polish to air quality.
Integrating Ventilation With Heating and Air Conditioning Systems
Balancing Static Pressure and Airflow
An improperly balanced system can rob conditioned rooms of comfort while overworking blowers. HEP technicians:
- Measure static pressure at multiple points along supply and return paths
- Adjust damper positions and fan speeds as needed
- Recommend duct modifications or additional returns to alleviate bottlenecks
Balanced pressure extends equipment lifespan and ensures uniform comfort throughout the building.
Zoning Strategies for Multi-Level Structures
Two-story homes and retail spaces with distinct usage zones benefit from individualized climate control. HEP installs:
- Motorized dampers linked to zone control boards
