Why HVAC mail has to follow the weather
An HVAC company gets most of its calls on the hottest and coldest days of the year, and very few in between. Direct mail is the tool that fills those quiet weeks: a tune-up offer that lands before the season turns brings in scheduled work, and the customers who say yes become the easiest replacement sales later.
The homeowner who calls during a breakdown is in a different position. Their system has stopped, the house is uncomfortable, and they call the company they already know. A card mailed a month earlier, or a sticker-sized reminder of who serviced the unit, is often the reason that call comes to you.
So HVAC mail does two jobs at once: sell planned maintenance in the shoulder seasons, and keep your name in the house for the emergency.
An HVAC mailing calendar
Mail two to four weeks before demand rises, not when it arrives. By the time the first heat wave hits, your schedule should already be full of tune-ups you sold in the spring.
- Late winter to early spring: air conditioning tune-up offer, mailed before the first warm weeks in your area.
- Early summer: maintenance plan enrollment to the same routes, aimed at people who skipped the spring check.
- Late summer to early fall: furnace or heat pump safety check and tune-up.
- Early winter: a reminder card with your emergency number, timed before the first hard freeze.
The exact weeks depend on your climate. A contractor in a hot southern market leans toward cooling all year, while a northern contractor puts more weight on the fall heating mailer.
Which pieces work for heating and cooling contractors
The seasonal postcard
The 6.5″ × 9″ postcard is our most economical size that still qualifies for EDDM (Every Door Direct Mail), the USPS service that reaches every address on a carrier route without a mailing list. It holds a seasonal headline, one tune-up offer, a photo of a technician at a unit, and your phone number. 10,000 cost $779, which is enough for two seasonal drops to 5,000 homes.
The door hanger after every call
A technician who finishes a service call can hang a 3.5″ × 8.5″ door hanger on the neighboring houses before leaving the street. Homes on one street were often built at the same time, so their systems tend to age together. 2,500 cost $327.20 on 100lb cover.
NCR work orders
Techs who write tickets on site can use 8.5″ × 11″ NCR forms (carbonless sets that make a customer copy and an office copy at once). 1,000 2-part sets cost $279, and 3-part sets and red or black numbering are available.
Selling maintenance plans on a postcard
A maintenance plan is easier to sell on paper than over the phone in July. Use the back of the card to explain it in plain terms: what the visits include, when they happen, and what members get, such as priority scheduling or a discount on repairs.
Keep the front to one offer with one price you set. A tune-up card that also advertises duct cleaning, water heaters and indoor air quality reads as clutter. Save those for separate mailings.
Show the details HVAC buyers check: your license number where your state requires one, the brands you service, "licensed and insured", and the towns you cover. A photo of your own van and technician does more for trust than a stock photo of a smiling family.
Finding the homes most likely to need HVAC work
Homes built in the same years tend to have systems of the same age, so a neighborhood where you replaced one unit often holds dozens more near the end of their service life. Mail the carrier routes around your recent replacements first.
Owner-occupied homes are the better audience for replacement and maintenance plans, since renters rarely make those decisions. The USPS EDDM map lets you compare routes by household data before you choose them.
A year of HVAC mail, priced
One season's worth of printing for a small HVAC company: 10,000 6.5″ × 9″ postcards ($779), 2,500 3.5″ × 8.5″ door hangers ($327.20) and 1,000 2-part NCR work orders ($279). The printing total is $1,385.20 before shipping.
The postcards cover a spring cooling drop and a fall heating drop to the same 5,000 homes. If you want a larger card for a single big mailing, 10,000 6″ × 11″ postcards cost $799.
Use the EDDM cost calculator to add shipping and USPS postage for your household count. Our HVAC seasonal direct mail calendar covers the full year month by month, and the break-even calculator shows how many tune-ups or plan sign-ups pay for the mailing.
