Review how outdoor air and particles enter your home.
RJ Sam’s works on the indoor air quality equipment already in your home, across brands. We assess the equipment and explain compatible repair, care or replacement options.
Tell us what’s happening
How is outdoor air entering?
Windows, doors, leaks and mechanical ventilation can bring outside air indoors.
- Air-entry patterns
- Describe the rooms affected and the conditions when the concern appears.
- Particle filtration
- Review cabinet fit and airflow before choosing a capture upgrade.
- Outside-air controls
- We’ll check how outside air enters your home and identify any ventilation equipment.
Before you agree
What should the plan include?
Review what the work addresses, the equipment and connections involved, and what is excluded. The proposed work and price should be clear before you approve it.
Filtration, humidity and ventilation guide

- Care and operation
- Include replacement filter details and operating guidance for the selected arrangement.

Before you decide
Questions before deciding
Review the decision and the service involved before requesting a follow-up.
What should the outdoor-air assessment review?
Intentional fresh-air inlets, leakage paths, filtration, controls and the operating pattern you notice. Increasing outdoor air is not the answer to every outdoor-air concern. The plan should explain when and how the proposed system operates; this page does not report current local air conditions.
Should I always bring in more outside air?
Outside-air quality and humidity matter. Review your ventilation arrangement and controls rather than applying one setting to every condition.
Does a particle filter remove gases too?
Ordinary particle filtration is not designed to address every gas or odor. Those concerns need source-specific investigation.
What should I do during outdoor smoke?
Follow current local public-health guidance and the appropriate operating guidance for your equipment. This page does not report current conditions.
