HVAC System Cleaning:
When it comes to fighting dirty indoor air, United Air Care has what it takes to help everyone breather easier and feel better in the workplace. Poorly maintained HVAC systems harbor mold, fungi, bacteria, pollen, dust mites and other disease carrying biological pollutants which are re-circulated through forced air systems. Given the right conditions of moisture and temperature, these contaminants can flourish in the ductwork and be carried out into the workspace where humans are exposed.
United Air Care features a five-point program for the highest quality and customer satisfaction for HVAC System Cleaning and Air Duct Cleaning
- The cleaning of every component of the HVAC system conforming to the standards established by NADCA and EPA guidelines. This includes the return system, air handler, heat exchanger, blower, coils, distribution plenum, supply ductwork and the diffusers/registers.-
- Disinfecting of non-porous system components with an EPA registered biocide (if/when necessary).
- Identification and repair of air leaks throughout the HVAC system on an access-permitting basis.
- Examination of the HVAC system and reporting back to you on any conditions in need of repair.
- Resurfacing the air handler with an EPA registered anti-bacterial/anti-fungal coating to help prevent future growth of fungus and bacteria and degradation of the internal fiberglass liner.
HVAC Systems are excellent breeding grounds for harmful airborne contaminants to gather and then spread throughout a building. When HVAC Systems are contaminated with dust, mold, construction debris, bacteria, or insulation fibers the indoor air quality of the facility suffers, putting patients at a higher risk in healthcare facilities, and damaging employee productivity for businesses. When the contaminants are combined with varying temperatures, humidity levels, and airflow in the HVAC System the indoor air environment can dramatically suffer. Not only are there additional health risk with a dirty HVAC System, but a system's operating and efficacy standards are impaired, resulting in higher operating cost for the facility.
Air Handler
Our technician will remove blower for thorough cleaning. If needed, we will disassemble the blower and wash the fan and housing. If disassembly is not required, we will air-wash the blower with a high-pressure nozzle.* After rinsing the coil, the tech will wipe down the primary drain pan and make sure that the drain is clear. Finally, we contact-vacuum all insulation and clean all hard surfaces with degreaser. After duct cleaning, an EPA-registered sanitizer (usually Sporicidin) is applied and allowed to dry by running the blower for fifteen to thirty minutes.
Return Ductwork
We connect the recovery unit to the return ductwork and clean the duct with an air-forced agitator to remove contaminants. We typically hand clean the plenum attached to the air handler on a split system.
Supply Ductwork
The technician will connect the recovery unit to the supply ductwork and clean the branch runs. We start from the vent boot areas inside the ceiling, wall, or floor and use the air agitator to move debris toward the trunk. After all inside runs are clean, we move to the attic or crawl-space where we access and clean the trunk by working back toward the recovery unit.
Duct Access & Restoration
All access-openings that are cut into the ductwork are repaired and sealed by NADCA standards. Our technicians never cut accesses into flex duct. We use metal patches, screws, and masking tape to close any openings cut into metal ductwork. We also repair insulation with tape and staples and reseal the entire area with masking tape.
Restoration & Cleanup
At United Air Care Inc., we pride ourselves in being able to complete the job in your home or office and leave no evidence of our presence, other than cleaner air. The negative pressure process and the use of drop cloths controls almost all of the debris involved with the job, but the work typically produces a small amount of dust. After reinstalling registers and moving our equipment back to the truck, we will dust and vacuum our work areas and make sure that your home is left as clean—if not cleaner—as we found it.
