When it comes to your HVAC system, where you place your air handler can make or break how efficiently your system runs. It’s more than just squeezing it into whatever space is available—it’s about airflow, maintenance access, noise control, and long-term durability.
So, where should your air handler go? Let’s take a look at the most common locations, what works (and what doesn’t), and how to make the smartest call for your setup.
Why Air Handler Placement Matters
Your air handler’s job is to circulate conditioned air throughout your home. If it’s not positioned right, your whole HVAC system might work harder than it should, costing you in both performance and energy bills.
