3 Fast Visual Checks for Your Dunstable HVAC System Before Winter Kicks In
Before calling for air duct cleaning in Dunstable, grab a flashlight and inspect these three spots, safely and without tools. 1. Vent Covers: Remove and vacuum dust from supply/return vents (use a HEPA filter to trap allergens). 2. Register Grilles: Look for bent or blocked grilles, straighten gently with a butter knife (never pry with screwdrivers). 3. Duct Seams: Check visible seams near joints for gaps (use painter’s tape to seal minor tears temporarily). Pro Tip: If your Dunstable home has forced-air heating, focus on vents near bedrooms, these circulate air longer. Read our vent cleaning guide for deeper tips.
