Dana Thompson Tanks and Soil: Top-Rated HVAC Repair Serving Portland, OR 97214

Our process begins with a thorough site assessment and soil sampling, as required by Oregon DEQ. We then safely remove or properly abandon the tank in place. If any soil contamination is found, we manage the environmental cleanup to meet state standards, ensuring your property is safe and compliant. We handle everything from permitting to final reporting.

While we don't service HVAC units, inefficient or leaking systems often stem from outdated fuel sources. We address the root cause by safely decommissioning old, underground heating oil tanks that can be a liability. For homes switching to modern systems, we also install new above-ground tanks, providing a secure, efficient fuel solution that can contribute to better overall home energy performance.

Radon is a naturally occurring, radioactive gas that can seep into homes from the soil and is the leading cause of lung cancer among non-smokers. Our NEHA-NRPP certified professionals provide accurate testing. If elevated levels are found, we design and install effective radon mitigation systems to reduce the gas to safe levels, protecting your family's long-term health.
