Most HVAC contractors leave filter money on the table. A homeowner asks where to buy filters, the tech says “Home Depot or Amazon,” and that's the end of it. Meanwhile, the customer spends $400–$800 per year on filters that could have been yours — with essentially zero added work.
This guide walks through exactly how to add filter subscriptions to your HVAC business: what to charge, how to pitch it, how to handle objections, and which tools make it genuinely hands-off.
Why filter subscriptions are the easiest recurring product you can sell
Every home with a forced-air HVAC system needs filters replaced 4–12 times a year. That's a guaranteed, repeat need. Unlike service calls (episodic) or installs (rare), filter subscriptions hit the trifecta:
- Predictable: every customer needs the same thing on a schedule.
- Low-touch: ship a filter, get paid — no truck roll required.
- Sticky: once a customer is on autoship, they rarely switch.
Even a modest 100-subscriber list at $25/month is $30,000/year in recurring revenue — on top of your normal service and install work.
What to charge for a filter subscription
Pricing depends on filter size, MERV rating, and delivery frequency. Here's the benchmark range most HVAC contractors land on:
- MERV 8 / standard size (16x25x1): $12–$18 per filter, delivered every 60–90 days.
- MERV 11 / allergy filter: $18–$25 per filter.
- MERV 13 / high-efficiency: $25–$35 per filter.
- 4–5" media filters: $50–$75, delivered every 6–12 months.
The sweet spot for most homes is 4–6 filter shipments per year. Charge slightly more than Amazon (+20–30%) and frame the premium as “right size, right MERV, delivered on time.” Most customers will happily pay for the convenience and the fact you picked the right filter for their system.
The 3 best times to pitch a filter subscription
You don't need a sales team. You need three trigger moments your techs already encounter on every job:
1. At the point of install
Brand-new system, homeowner in a buying mood — this is your highest-converting moment. Build the filter subscription signup right into your install checklist. In the HVAC industry, about 40–50% of new install customers will say yes if you ask.
2. During seasonal tune-ups
Your tech is already standing in front of the furnace. Pull out the dirty filter, show the homeowner what they've been breathing, and offer the subscription as the easy fix. Closing rate here is usually 10–15%.
3. After a repair
Post-repair is a trust high point. If the problem was dirt-related (common on coil-freeze or blower issues), tie the subscription to the fix: “Here's how we keep this from happening again.” Conversion: 5–8%.
How to overcome the most common objections
“I just grab them from Home Depot.”
Fine — but Home Depot doesn't know your system, and the wrong MERV can starve airflow. We match the filter to your equipment and deliver it before you need it. Same price range, zero thinking required.
“I don't want to be locked in.”
No contract. Cancel anytime. Pause if you go on vacation. It's a convenience service, not a commitment.
“How do I know the right size?”
We size it for you based on your system. If you're with us, we already have it on file.
The tools that make it actually hands-free
The reason most HVAC contractors don't run a filter subscription isn't the idea — it's the logistics. Inventory, shipping addresses, renewal tracking, billing. Do it manually and it'll drain more time than it earns.
The fix is to run it through a system that handles fulfillment, shipping, and recurring billing for you. DinoQuote's branded filter store plugs into your existing website — customers sign up, the platform handles the rest, and you earn commission on every order with zero inventory.
Mistakes to avoid
- Don't stock inventory. Unless you have warehouse space, let a fulfillment partner ship direct.
- Don't skip branded packaging. Every delivery is a touchpoint. Your logo on the box means the homeowner thinks of you, not Amazon.
- Don't over-engineer pricing. One simple price per filter size is easier to sell than 15 variants.
- Don't forget the sticker. Put a branded QR-code sticker on the furnace. Every time someone looks at the system, they see your name.
The compounding upside
Filter subscriptions aren't just revenue — they're retention insurance. When you're mailing a customer something every 60 days, the odds they call someone else for a repair or replacement drop close to zero. Over 5 years, that retention advantage is worth 10x the filter revenue itself.
Start with your existing book. Offer it at the next 20 service calls. You'll have 5–10 subscribers within a month — and a system that funds itself from there.
Want to skip the setup?
If you'd rather not build the filter store, billing, and fulfillment yourself, DinoQuote handles all of it. You get a branded filter store on your website, automatic subscriptions, and commission on every order — fully integrated with your existing quoting and maintenance plan workflow.
