Why Timing Matters for Shoulder Season Maintenance
Are you ready for the October maintenance rush. Probably not.
Data shows October and November rank as the busiest maintenance months for HVAC contractors, creating a bottleneck that leaves customers waiting up to two weeks for service.
By the time most customers think about heating maintenance, it’s already too late. They call when the first cold snap hits, and suddenly everyone wants their furnace checked at once. This creates a scheduling nightmare that forces you to rush through jobs, miss important safety checks, and work overtime that could have been avoided.
Changing over from cooling to heating is a process that requires careful inspection and preparation. When systems sit dormant for months, problems develop that only manifest when they’re first fired up – usually on the coldest day of the year.
What’s Breaking Down This Winter (And Why)
After sitting dormant all summer, heating systems develop predictable failure points that smart technicians check before problems occur. Here are the top components to inspect during September maintenance:
- Circulation Pumps: These top the failure list after summer inactivity. Pump seizure due to 3-4 months of dormancy is a primary breakdown cause. A simple manual rotation during September can prevent an expensive mid-winter replacement.
- Induced Draft Motors: These critical components often seize after months of inactivity due to moisture infiltration and bearing lubricant thickening. The bearings in these motors are particularly vulnerable to corrosion when the system isn’t running regularly. A preventative check includes testing for smooth operation, proper amperage draw, and inspecting wheel clearance before winter demand pushes these motors to failure.
- Ignition Systems: Ignitors frequently fail due to exhaust gas recirculation during startup. Testing spark location and conductivity now prevents no-heat calls later.
- Burners: Summer humidity causes rust and corrosion on burner surfaces, leading to improper flame patterns and inefficient combustion when winter arrives. Carefully inspect burners for warping, rust, and proper alignment, then clean thoroughly with appropriate brushes and compressed air. Many techs skip this step, but it’s essential for preventing carbon monoxide issues and ignition failures.
- Flame Sensors: These develop contamination buildup during the off-season that leads to system failures. A quick cleaning in September ensures reliable ignition when temperatures drop.
- Heat Exchangers: Heat exchanger inspection deserves special attention during September maintenance. Even small cracks can release deadly carbon monoxide into living spaces when systems activate for winter. CO is known as the silent killer because it’s odorless, colorless, and dangerous at just 70 ppm, with 400 ppm potentially causing death within hours. Professional-grade testing equipment allows technicians to check ambient air, mechanical rooms, and flue gas during maintenance visits – any reading above 200 ppm in flue gas or detection in the air stream indicates an immediate safety hazard requiring system shutdown.
- Condensate Drains: One of winter’s most overlooked failure points is condensate drainage systems in high-efficiency furnaces. After months without operation, algae growth, debris accumulation, and trap evaporation create perfect conditions for water backups that trigger pressure switches and shut systems down. Many emergency “no heat” calls are simply condensate issues that could have been prevented with September maintenance. Thoroughly flush these lines, verify proper trap depth, and consider adding condensate treatment tablets as preventative maintenance
- Control Boards: The “brain” of modern furnaces often fails after power surges during summer thunderstorms. Testing all functions during the mild weather allows for planned replacement rather than emergency service. Learn more about control board components here.
January experiences the highest breakdown rate at 15% of annual heating system failures, followed by December at 12%. By addressing these components during September’s maintenance sweet spot, you’re preventing the most common emergency calls while protecting your customers’ comfort and safety.
Immediate Actions in August
The time to act is now, not when the rush hits. Here are the concrete steps you can take in early august to leverage the September sweet spot:
Customer Communication Templates
Start with your existing customer base. Send a simple email with this message:
“Beat the October rush! Schedule your heating system maintenance in September and receive priority scheduling, our thorough 21-point safety inspection, and peace of mind before the cold weather hits. Plus, mention this email for $25 off when you book this week.”
For text messages, keep it even simpler:
“HVAC Alert: Book your heating maintenance in September to avoid the October rush and potential parts delays. Reply YES for priority scheduling.”
These templates have produced open rates of 20% for email and 98% for text messages, significantly outperforming industry averages.
How to Pitch September Maintenance During AC Calls
Every summer service call is an opportunity to book fall maintenance. Here’s a script that works:
“While I’ve got your AC running great today, I noticed your heating system hasn’t been checked since last year. Most of our customers book their heating maintenance in September to avoid the October rush when everyone calls at once. Would you prefer a morning or afternoon appointment in the second week of September?”
This approach uses the psychology of choice rather than yes/no questions, increasing booking rates by up to 35%. By presenting it as something “most customers do,” you’re establishing a social norm that makes the decision easier.
The Business Case for September
As a solo technician or small shop owner, September maintenance offers a direct path to more stable income and better work-life balance. While emergency calls might seem more profitable at $950 versus $250 for maintenance, consider the hidden value: maintenance calls take half the time, create repeat customers, and can be scheduled on your terms. This means you can complete 6-8 maintenance visits daily compared to 3-4 emergency calls, with less stress and more predictable hours.
For small operations, simple maintenance agreements don’t need fancy software or complicated contracts. Start with a basic one-page agreement offering two seasonal checks (fall and spring), priority emergency service, and a 10% discount on repairs. Price it reasonably at $199-299 annually, and begin by offering it to your most satisfied customers. Even securing just 25 maintenance agreements creates a reliable $5,000-7,500 revenue base that helps smooth seasonal income fluctuations.
The beauty of September maintenance for small shops is that it transforms your business model from “waiting for the phone to ring” to proactively scheduling your workload. While we recommend you use a proper fleet management solution (like Housecall Pro), you can use a simple spreadsheet to track customer equipment age and maintenance history, then group appointments by neighborhood to maximize efficiency.
Many successful one-person operations report that maintenance agreements eventually represent 30-40% of their total revenue while requiring only 20% of their labor hours – making them the most profitable aspect of their business.
Building Long-Term Strategy
September’s calmer pace creates the perfect opportunity for training newer technicians before emergency season hits. Pairing experienced professionals with apprentices during maintenance calls allows for hands-on learning without the pressure of emergency situations. Companies report technicians trained through structured September maintenance programs experience 40% lower error rates during their first heating emergency season, building the reliability and discretionary effort that distinguish successful HVAC professionals.
Perhaps most importantly, strategic September scheduling dramatically improves technician quality of life by spreading workload more evenly throughout the year. This approach helps professionals avoid the 60+ hour weeks that contribute to our industry’s troubling 18-22% first-year turnover rate. Companies implementing structured September maintenance programs report a 35% reduction in technician overtime hours during winter months and corresponding 27% decrease in turnover. This creates space for both excellent customer service and technician work-life balance, essential for long-term career satisfaction.
Your September Action Plan
Here’s your action plan to make it happen:
- Early August: Set up a simple email and text campaign to existing customers promoting September maintenance.
- During Every AC Call: Pitch September heating maintenance using the choice-based script.
- Create Your Packages: Develop tiered maintenance offerings that provide clear value while maintaining healthy margins.
- Train Your Team: Ensure all technicians understand the technical and business benefits of September maintenance so they can confidently communicate them to customers.
- Document Everything: Use digital documentation tools to thoroughly record all findings during September maintenance, creating a baseline for future service.
The difference between a good technician and a great one often comes down to five minutes of extra attention. September maintenance gives you the time to be thorough, catch problems before they become emergencies, and build relationships that last beyond a single service call.
Your customers get reliable heating when they need it most. You get a more predictable schedule and income stream. Everyone wins in the September sweet spot.
