Maintaining Your Indoor Air Environment
Air Handler Units are designed to improve the quality of air delivered through your HVAC system. Typical use results in typical wear and, eventually, they can develop water leaks and component and casing deterioration. When this occurs, their effectiveness is reduced. Any contamination resulting from the deterioration of the unit is circulated via the HVAC system.

When regular maintenance does not take place, the unit can become totally non-functional.

These units can be restored…but the first step is an accurate inspection from a certified technician to determine whether restoration or replacement is the most cost-effective solution. Our assessments include a detailed Condition Report for your review so that you can make a truly informed decision.
