When Your HVAC Stinks: Smells You Shouldn’t Ignore

April 17, 2025

When your HVAC system kicks on, you don’t expect to catch a whiff of something strange. Whether it’s a musty smell, something burning, or a scent you can’t quite place, any odor from your vents can be annoying at best and a warning sign at worst. Some odors mean your system needs a quick clean while others could point to something more serious. Knowing what’s normal and what isn’t helps you respond quickly before small problems grow. Musty Smells That Linger When you walk into your house and catch a damp or musty smell, your nose might be picking up something from inside your HVAC system. This often points to moisture where it doesn’t belong. If water collects in the drain pan or sits inside ductwork without a way to dry out, it becomes a perfect place for mold or mildew to grow.

Tips for Fixing Uneven Cooling in Your Home

April 20, 2019

Uneven cooling can be uncomfortable. Air conditioning is meant to keep your entire home cool and comfortable when it’s hot outside. Over time, factors like age, dirty filters, and ductwork issues can cause your cooling system to operate less than optimally. If you’re too hot in one room and too cold in another, then it’s time to act. Here are a few ways to fix uneven cooling in your home. Check Your Air Vents Look around your home to determine if there are any dirty or blocked vents. The vents and registers can cause uneven cooling when furniture or other items are blocking them.
