Pre-configured inspection and maintenance kits for commercial HVAC systems.
A concrete product with a clear subject and real-world context.
This page frames a concrete subject instead of using a generic heading. It explains what is being considered, why it matters in the site's context, and what detail a reader can expect next. The copy is intentionally plain and specific, so it reads like a real content item.
A focused product built around practical decisions and constraints.
This item focuses on practical use, tradeoffs, and decisions that a reader may recognize. It avoids broad promotional claims and keeps the topic tied to a clear situation. The description gives enough substance for a real page rather than a placeholder card.
A grounded product that adds a different angle without repeating the others.
This page gives the third item its own reason to exist. It covers a separate angle, includes concrete context, and avoids repeating the same promise in different words. The result should feel like a planned article, project, review, or offer.
Each service targets a measurable aspect of commercial HVAC performance, from air turnover to particulate removal.
We measure actual air changes per hour in open-plan zones using tracer gas decay and capture hoods. Reports include comparisons against ASHRAE 62.1 minimums and recommendations for damper adjustments or fan speed changes.
We inspect installed MERV and HEPA filters for loading, bypass leakage, and pressure drop. Each filter bank is logged with a particle count before and after, so you know the real removal rate — not just the rated spec.
Mineral dust and construction debris are removed using negative air scrubbing and rotary brushing. We document pre- and post-cleaning pressure differentials and provide a visual inspection log from borescope footage.
The following provisions govern the interpretation of our inspection reports, service agreements, and technical recommendations. These definitions remove ambiguity and establish a shared baseline for all commercial ventilation audits.
All reported air changes per hour (ACH) are calculated using the tracer gas decay method with sulfur hexafluoride (SF₆) per ASTM E741. Measurements reflect steady-state conditions under normal HVAC operation. Results do not account for temporary door openings, window usage, or occupant density fluctuations during the test period.
HEPA and MERV classifications cited in our reports follow IEST-RP-CC001 and ASHRAE Standard 52.2 respectively. Efficiency claims refer to initial particle capture at rated airflow. Filter loading, bypass leakage, and installation gaps may reduce real-world performance and are noted separately in each inspection.
The term "mineral dust" refers specifically to non-organic particulate matter with a Mohs hardness of 5 or greater, including silica, limestone, and gypsum particles. Our duct cleaning protocols target these abrasive materials using negative air scrubbing and HEPA-filtered vacuum extraction. Organic debris, mold, or biological growth require separate remediation procedures.
Our technical reports cover only the ductwork, air handling units, and filtration systems explicitly listed in the service agreement. Adjacent building systems, fire dampers, and electrical components are excluded unless specifically requested. Recommendations are advisory and do not substitute for local building code compliance or manufacturer maintenance schedules.
Insideaha provides technical assessments and cleaning services based on industry-standard methods and calibrated equipment. We are not a medical, epidemiological, or public health authority. No claim regarding disease prevention, pathogen reduction, or health outcomes is implied or guaranteed. All service agreements are governed by the terms outlined in our contract, which supersedes any general statements on this platform.
