HVAC play · Postcards
HVAC postcards that tell you which homeowners are ready to book.
Most HVAC postcards are a stock photo, a coupon, and a phone number mailed to every door. Spur writes a card for each home that names its age and the season ahead, prints it, mails it USPS first-class, and alerts your office the moment someone scans the QR code.

The problem
Most HVAC postcards look the same, and nobody knows who read them.
A 2021 build with a two-year-old heat pump gets the same replacement pitch as a 1998 home on its second furnace. Half the message misses.
If the phone rings, you can't tell which card, street, or offer did it. So next season's card is a guess too.

AI draft for Marcus B. · 4417 Wexford Ridge Dr
YOUR 2008 FURNACE HAS A BIG WINTER AHEAD.
Hi Marcus, most homes on Wexford Ridge were built around 2008. If yours still has the original furnace, it's heading into its 17th winter.
Our $89 fall safety check covers the heat exchanger, flame sensor, igniter, filter, and a carbon monoxide test. You'll get a written report and an honest read on how many winters the system has left.
Scan the code to pick a time. We're booking October and early November now.

What makes an HVAC postcard work
A postcard has about three seconds between the mailbox and the recycling bin. In that time the homeowner reads the headline, glances at the image, and decides if the card is about them. The cards that survive say something specific to that house: its age, its street, the season it's heading into. "Your 2008 furnace has a big winter ahead" gets read. "Fall savings on heating!" doesn't.
Lead with one offer. A card with a tune-up price, a financing rate, a referral bonus, and a maintenance plan reads like an ad and gets treated like one. Pick the offer that matches the home's age. For homes with systems roughly 8 to 14 years old, a pre-season check or a maintenance plan is the natural next step. For homes 15 years and older, a free replacement estimate or a second opinion on a big repair quote is the stronger offer. ENERGY STAR suggests considering replacement for air conditioners and heat pumps over 10 years old and furnaces over 15, which gives you a fair, credible way to frame it.
Size and format matter less than most vendors suggest. A 6×9 card gives a headline room to breathe and stands out from letter-size mail. A 4×6 costs less and works for repeat touches to the same list. Either way, keep the back simple: your logo, license number, one sentence of proof (years in business, review count, or a nearby job), the offer, and a QR code with a short call to action like "Scan to pick a time."
The QR code is what turns a postcard from a brand impression into a lead source. When each household has its own code, a scan tells you exactly who's interested, which version of the card they got, and when. Call scanners back the same day. A homeowner who scanned a furnace check card on Tuesday night is a much warmer call than any purchased lead.
Finally, plan the second card before the first one mails. Most responses come from repeat exposure. Send a follow-up three to four weeks later to homes that didn't scan, with a new headline but the same offer, and stop mailing anyone who booked.
16×return on a year of Spur Team from one $9,500 replacement
One replacement pays for a year of postcards.
- Spur Team: $49/mo billed annually = $588/yr
- 1,000 postcards on Team at $0.94 each = $940
- One $9,500 system replacement = 16× your subscription, and 6× the software and postage combined

FAQ
HVAC postcard questions
What should an HVAC postcard say?
One headline about the homeowner's house or season, one offer, one line of proof, your license number, and a QR code with a clear action. Cards that name the home's build year or street get read far more often than generic seasonal coupons.
What size postcard is best for HVAC marketing?
6×9 for a first touch, because it stands out from letter mail and gives the headline room. 4×6 works well for follow-up cards to the same list. Spur prints both.
How many HVAC postcards should I send?
Enough to reach every target home at least twice. A focused list of 500 to 1,500 owner-occupied homes with the right system age usually beats 5,000 saturation cards to every door.
Are HVAC postcards better than door hangers?
Door hangers take crew time, only reach homes your techs can walk to, and give you no record of who read them. Postcards reach the owner's mailing address, and a per-household QR code tells you who scanned.
Can I use my own postcard design?
Yes. Upload your design or start from a Spur template, then let AI fill in the per-home headline and body. Your logo, colors, and license number stay the same on every card.
