Locate and access filters

Log and advise
We note the date, size and type so you have a clear record and know when the next change is due.
Problems we fix
- Filters installed backwards, reducing filtration and straining the blower

- Incorrect filter size leaving gaps that allow unfiltered air to pass
- High-MERV filters installed in older systems not designed for the added resistance
Air Filter Replacement in Charleston — FAQ
How often should I change my air filter?
Most 1" filters need changing every 30–90 days. Thicker 4" and 5" media filters can go 6–12 months. Homes with pets or allergy sufferers typically need more frequent changes.
What MERV rating do I need?
MERV 8–11 works well for most homes and balances filtration with airflow. We can advise based on your system type and household needs.
Can a dirty air filter damage my HVAC system?
Yes. Clogged filters restrict airflow, causing the system to overwork, freeze evaporator coils and potentially fail the blower motor.
Air Filter Replacement across Charleston
Charleston's humid subtropical climate, salt air and active storm season are tough on homes — swollen doors, rusting hardware, mildew-prone caulk and storm-loosened trim are all common. Downtown's historic houses add original plaster walls and tight, detailed millwork, while West Ashley and the islands bring newer builds with their own quirks. Our pros are comfortable with both.
