Why the slow-season discount rarely pays off for HVAC contractors
The slow-season schedule goes soft and a rep tells you to run a discounted tune-up special. That discount does not create demand — it buys the cheapest buyers in the market and trains your base to wait for the coupon.

The schedule goes soft the same way every year. The last cold snap passes, the phone stops ringing three times a morning, and by the second week of the lull a distributor rep or a peer-group thread has the same answer waiting for you. Run a spring special. $59 for a tune-up, a coupon in the local mailer, and the promise underneath it: get a tech in the door now and the replacement work follows in July. It sounds like a plan because it feels like motion. Book the trucks, fill the calendar, ride out the shoulder season. Before you approve that spend, be precise about what a discount actually does to a home-services business, because the mechanics almost never match the pitch.
The slow season is not a price problem
Start with why the phone went quiet. It is not because your prices got too high in March. It is because nobody's system is failing in March. A furnace that limped through February and an air conditioner that has not been asked to run yet are both sitting there, working, invisible to the people who own them.
That single fact is the one the discount pitch ignores. As one veteran home-services marketer put it in ACHR News, marketing "does not create demand. It captures demand when equipment fails." Cutting the tune-up price does not make a working system break. It does not move a homeowner who was not going to think about their HVAC for another 8 weeks. What it does is lower the bar for the one group still willing to raise a hand in the off-season: people shopping on price. You have not generated new demand. You have discounted your way to the least valuable slice of a market that is not buying right now.
This is the reframe the whole decision turns on. A slow season is a demand-timing problem. A discount is a price tool. You are reaching for the wrong instrument, and reaching hard, because the calendar makes idle trucks feel like an emergency.
What the discount actually buys you
Follow the $59 tune-up all the way through your business and you find four costs the promotion never mentions.
The first is selection. A discount does not attract a random cross-section of homeowners. It attracts the ones who respond to discounts. The customer who books a $59 special because it is the cheapest one in the mailer is, by definition, the customer least attached to you and most likely to shop the next job too. The homeowner with a 15-year-old system on the edge of replacement is not hunting coupons in April. You are spending money to fill your bay with the lowest-propensity buyer in the market and calling it lead generation.
The second is capacity. Shoulder-season hours are not free hours just because the phone is slower. They are the only slack you get all year, and they are exactly when you should be doing the high-margin work you deferred during the summer crush and the maintenance visits your best customers already paid for. Spend those hours running loss-leader tune-ups for strangers and you have not filled dead time. You have crowded out your most profitable use of the one window that gives you any room to breathe. A recent industry report found that only 65% of the average HVAC technician's paid time is billable to begin with. The shoulder season is where you protect that number, not where you spend it on $59 visits.
The third is what the discount teaches your existing base. Homeowners are not stupid, and they talk. Run a spring special every year and you train the customers who would gladly have paid full price to wait for the coupon instead. You are not adding revenue. You are moving revenue you already had into a discounted bucket and thanking yourself for the volume. This is the same slow leak I described in why your HVAC company's average ticket keeps shrinking — the number on the invoice drops one reasonable-sounding decision at a time.
The fourth is the claim doing all the persuading: that the cheap tune-up converts into replacement sales. Maybe it does. The industry rule of thumb is that roughly 1 in 20 tune-ups should surface a replacement, a 5% conversion rate — and almost no shop running these specials actually measures its own number. You are asked to accept a conversion story on faith while the only measurable result, a truck full of price-shoppers, sits right in front of you. Worse, when a discount visit does convert, it often converts because the tech was incentivized to find something, and the homeowner who came in for a bargain now suspects they were upsold. That is not a customer for life. That is a one-star review waiting for a slow month of its own.
None of this is an argument that your tune-up visit is worthless. It is an argument that the discount attached to it is doing the opposite of what you were told. And if a smaller share of the calls you are already getting turn into booked work, the fix is upstream of price — I walked through that in why fewer of your home-services calls turn into booked jobs.
Where the value actually is
Here is the turn. The spring special feels like demand generation. It is demand harvesting, at a loss, aimed at the cheapest buyers you will meet all year. The contractors who grow through the shoulder season are not the ones with the best coupon. They are the ones who understood that the value was already sitting in their customer file and went to get it at full price.
The math backs this up plainly. The same ACHR analysis notes that 65% to 70% of a customer's lifetime value is realized in the first 18 months of the relationship, and that roughly 20% of revenue has to be replaced every year just to stay flat, given normal attrition of 17% to 21%. Read those two numbers together and the slow season stops looking like a hole to plug with strangers. It looks like the one stretch of the year with enough open time to actually work the base you have: renew the maintenance memberships that lapse quietly, follow up on the deferred repairs your techs already diagnosed and wrote down, and re-engage the customers who used you once two years ago and forgot you exist. That work is full-margin, it is warm, and it is invisible on a promotion calendar.
This is the same logic as refusing to rent your growth from a lead aggregator. I made that case in why home-services owners should stop buying leads from aggregators: every dollar spent buying the cheapest available stranger is a dollar not spent owning the demand you have already earned. The discount special is the same trade in a friendlier costume. The veteran marketer in that ACHR piece put the whole principle in one line worth taping to your office wall: contractors who consistently grow "do not treat marketing like a promotion calendar. They treat it like infrastructure."
Infrastructure is not glamorous and it does not fill the schedule by Friday. That is precisely why the discount keeps winning the argument. It offers the feeling of decisive action in a week when the phone is quiet and you want to do something. Motion is not the same as progress, and a booked truck is not the same as a profitable one.
So before you sign off on this year's spring special, spend 20 minutes doing the arithmetic the pitch skips. Pull the last 12 months and answer two questions. First, of the customers who came in on a discounted tune-up, what share ever bought anything else from you — the real conversion number, not the rule of thumb. Second, how many of your existing members and past customers have work you already diagnosed and never followed up on, or memberships that lapsed without a call. One of those numbers is almost always dramatically larger than the other, and it tells you exactly where your shoulder-season hours belong. Do that before you touch the price. The trucks will stay just as busy, and you will keep the margin instead of mailing it away.
