Why Choose HVAC Filter Auto Delivery?

Routine filter replacement is one of the easiest and most affordable ways to support HVAC system performance, maintain airflow, and improve indoor air quality.

The challenge isn't changing the filter.

The challenge is remembering to order one.

Our recurring delivery program helps homeowners stay on schedule by automatically shipping replacement filters and maintenance products based on their preferred delivery frequency.

No last-minute trips to the hardware store.

No wondering when your filter was last replaced.

Just reliable HVAC maintenance delivered to your door.


More Than Just Furnace Filters

While furnace filters are among our most popular subscription products, they're not the only items eligible for recurring delivery. Many homeowners use auto delivery for humidifier water panels, dehumidifier filters, refrigerator water filters, and other indoor air quality products they replace throughout the year.

The goal is simple: less time tracking maintenance schedules and more time enjoying a comfortable home.


How Often Should HVAC Filters Be Replaced?

The ideal replacement schedule depends on your filter type, indoor air quality needs, pets, allergies, and overall HVAC usage.

Filter Type

Typical Replacement Schedule

1-Inch Filters

Every 30–60 Days

2-Inch Filters

Every 60–90 Days

4-Inch Filters

Every 6–12 Months

5-Inch Filters

Every 6–12 Months

Homes with pets, allergy concerns, construction dust, or heavy HVAC usage may benefit from more frequent filter changes.


Find the Right Filter for Your System

Before starting a recurring order, it's important to verify the correct filter for your HVAC system.

We recommend using the part number from your current filter whenever possible. While many filters share similar nominal dimensions, actual filter sizes can vary slightly between manufacturers.

Most filter part numbers can be found directly on the filter frame. If a filter is not currently installed, check your HVAC equipment, filter cabinet, or manufacturer's documentation for recommended replacement information.

Selecting the proper filter helps support healthy airflow, maintain indoor air quality, and keep your HVAC system operating efficiently.

Important: Ordering based solely on filter size can sometimes result in purchasing the wrong replacement filter. Whenever possible, verify the manufacturer's part number before ordering.


Complete Control Over Your Subscription

Life changes, and your subscription should be able to change with it.

Once you create a customer account, you'll be able to update payment methods, adjust delivery schedules, skip shipments, change products, or cancel future orders directly from your account dashboard. No phone calls. No long hold times. Just a few clicks whenever you need to make a change.


Subscription Renewal Reminders

Before your next recurring order is processed, we'll send a reminder email so you have time to review your upcoming shipment, update your schedule, make product changes, or cancel future deliveries if needed.

Please verify that your email address is current and check your spam or promotions folder if you do not see the reminder notification.

No. Recurring orders and subscriptions must be created directly by the customer through our website.

This includes furnace filters, water panels, humidifier filters, dehumidifier filters, refrigerator water filters, and other products eligible for recurring delivery.

Ordering your subscription and creating an account online ensures you can access and manage your account, update payment information, modify delivery schedules, make product changes, and cancel future deliveries as needed.

If you have questions about an out-of-stock subscription item, please contact our customer service team for assistance.

How do I know I'm ordering the correct filter?

We recommend verifying your filter's part number whenever possible. While many filters are marketed using nominal sizes, actual dimensions can vary between manufacturers. Using the part number from your current filter or HVAC equipment helps ensure you receive the correct replacement filter.
