Drain Pan Restoration & Preservation services.
Our AHU and drain pan restoration services address corrosion, microbial growth, and water damage that can compromise an AHU’s performance. Proper restoration helps prevent moisture-related issues, supports condensate management, and reduces the risk of indoor air quality concerns. Our OSHA certified technicians use a 2-part self-leveling epoxy for drain pans and a 2-part vertical paint for AHU fan housings.


Why Drain Pan Maintenance matters!
A deteriorating or leaking drain pan can cause:
- Water damage to ceilings, walls, and floors
- Mold and microbial growth due to excess moisture
- Costly repairs or premature system replacement
Once a drain pan begins to fail, fixing it can be challenging, and full replacement often involves significant expense and downtime.
Our Drain Pan Restoration solution.
At Air Quality Systems, we offer a specialized coating application designed to:
- Seal existing leaks
- Prevent corrosion and further deterioration
- Extend the life of your drain pan and HVAC system
Our restoration process is a cost-effective alternative to full drain pan replacement—helping you avoid costly repairs while protecting your property.


Professional Air Handler Unit (AHU) Cleaning services.
In addition to our comprehensive HVAC system and air duct cleaning, Air Quality Systems offers specialized air handler unit (AHU) cleaning as a stand-alone service.
Why Clean Your Air Handler Unit Separately?
There are many reasons to focus on cleaning just the AHU, including:
- Phased cleaning projects to fit your budget
- Targeting the AHU as the source of odors, dust, or microbial growth
- Incorporating AHU cleaning into a regular preventive maintenance program
The importance of AHU Cleaning.
Even with the use of high-efficiency filtration products, airborne particles inevitably bypass filters and accumulate inside the air handler unit. Over time, this buildup can:
- Reduce system efficiency
- Contaminate the ductwork downstream
- Increase the frequency and cost of full duct cleaning
- Reduce Indoor Air Quality and building occupant comfort
