Regular inspection and maintenance of HVAC system components will help to limit the need for any restoration or remediation projects, but as the components age they’ll eventually need to be replaced or repaired.
Some of the common work that we do on HVAC restoration projects includes:
- Repair / replacement of insulation – over time the constant heating and cooling, along with external environmental factors, will cause the insulation to breakdown. Damaged insulation should be replaced to avoid fiberglass and other potentially damaging particulates from circulating through the air in your building.
- Cleaning cooling coils and installation of UV-C lamps – the area near cooling coils and their condensate pans can be a breeding ground for mould and other moisture-loving bacteria and viruses. Cleaning this area and installing UV-C germicidal lamps will help reduce mould growth over the long-term
- Flexible duct replacement – mould and dust tend to build up in the bends and wrinkles of flexible ducting and once damaged it needs replacement.
- Antimicrobial treatment – cushion head boxes and grilles can suffer from mould and mildew contamination. Antimicrobial treatments will protect internal insulation for up to 10 years.
- Air fan and plenum restoration – dust and biofilm can settle on these units, descaling and applying corrosion control coatings will extend the lifetime of components.
- Millboard replacement and heater bank upgrades – after long-term use, millboard often contains active mould spores. Disinfecting and replacing affected surfaces will prevent mould from contaminating the indoor air as well as downstream HVAC components.
- Filtration Upgrades – all filters will at some point reach their load limit and need to be replaced. Checking filter frames are in good working order, free of damage and rust will prevent contaminated air from bypassing the filters.
- Installation of access panels – in some cases HVAC systems have been designed without easy access to areas that need regular inspection.
