Frequently Asked Questions
How often should I change furnace and home water filters?
Furnace filters commonly need replacement every 1–3 months depending on MERV rating, household pets, and dust levels. Whole-house water pre-filters are typically changed every 3 months (manufacturer guidance varies by cartridge), under-sink carbon cartridges around 6 months, and faucet filters roughly every 3–4 months. Always follow the specific product’s guidance and inspect filters visually for heavy soiling.
What tools are essential for a quick, correct filter change?
At minimum: a screwdriver set, adjustable wrench or pliers, utility knife, shop vacuum (small), nitrile gloves, and contractor disposal bags. For water housings, a sump wrench and pressure-relief valve are handy; for HVAC, an infrared thermometer or simple airflow gauge helps verify system changes.
How do I avoid leaks when replacing water filter cartridges?
Inspect and lightly lubricate O-rings with food-grade silicone grease, ensure housings are seated and hand-tight (avoid over-tightening), use the provided pressure-relief valve before opening housings, and confirm plumbing adapters match pipe thread and size. After replacement, run water and check all fittings for drips before leaving the area.
