Before you call a pro for Lexington air duct issues, run through this safety-first checklist. It covers the simple fixes you can try and the warning signs that mean it’s time to call Jason Nguyen Air Duct Cleaning Inc.
Step 1: Check the thermostat and airflow in your Lexington home
Start by confirming your thermostat is set to ‘cool’ or ‘heat’ and the fan is on. Walk through your Lexington home and feel each vent for airflow. If one room is noticeably warmer or cooler, it may point to a duct issue. Check for closed or blocked vents in bedrooms or less-used spaces. Lexington homes often have zoned systems, so ensure all zones are open. If airflow is weak everywhere, your filter might be clogged—replace it if it looks dirty. If the problem persists, move to the next step. Learn more about our full list of services.
Step 2: Inspect the air filter and replace if needed
Locate your air filter, usually near the furnace or air handler in your Lexington basement or utility closet. Pull it out and hold it up to the light. If you can’t see through it, it’s time for a new one. Use a filter with the same size and MERV rating (usually 8–13 for most Lexington homes). A clogged filter restricts airflow and can cause ducts to act up. Replace it every 1–3 months, especially during Lexington’s humid summers and cold winters. Always turn off the system before changing the filter. See request a free estimate / contact us.
Step 3: Look for visible duct damage or gaps in Lexington homes
Grab a flashlight and inspect accessible ductwork in your attic, basement, or crawl space. Look for disconnected joints, holes, or crushed sections—common in older Lexington homes with flexible ducts. Use foil tape or mastic sealant (not duct tape) to seal small gaps. If you see mold, rust, or insulation falling apart, stop DIY work. These signs often mean moisture or pest issues that require professional handling. Never crawl into tight ducts or attic spaces alone. Explore about our team and credentials.
Warning signs: Stop DIY and call a pro immediately
If you notice mold growth inside ducts, a musty smell that won’t go away, or signs of pests like droppings or nests, stop all DIY work. These issues can worsen indoor air quality and pose health risks. Also, if you see water stains or condensation around ducts, it may indicate a roof leak or HVAC problem. Never attempt to clean moldy ducts yourself—it can release spores into your Lexington home. Similarly, avoid sealing ducts with gaps larger than a quarter inch or if you suspect asbestos (common in pre-1980s homes). For details, see the areas we serve.
What you should never DIY in Lexington air ducts
Never use DIY duct cleaning machines or chemicals—these can damage ducts, void warranties, or spread contaminants. Avoid opening duct panels without proper tools or training, as sharp edges can cause injury. Don’t attempt to remove or replace ductwork yourself; improper installation can lead to energy loss or system failure. Also, skip sealing ducts with regular duct tape—it dries out and fails. For any work involving electrical components, gas lines, or mold, always call a licensed professional in Lexington.
