Marketing HVAC in the shoulder seasons

What the shoulder seasons are for

Every HVAC company knows the pattern. The first hot week brings a flood of no-cool calls, the first cold week a flood of no-heat calls, and in between there are weeks when technicians wait for work. Those in-between weeks, usually in spring and fall, are the shoulder seasons. They are the best time to do work that can be planned: maintenance, inspections, duct and air quality work and replacements that customers can schedule on their own terms.

Shoulder marketing has two goals. The first is to fill idle hours now. The second is to reduce the peak crush later, because a system that was tuned in April is less likely to fail in July, and a customer who planned a replacement in October is not an emergency in January. Both make your company calmer and more profitable.

The challenge is that homeowners are not thinking about their HVAC when it is 65 degrees outside. Your marketing has to give them a reason to think about it now.

Messages that work when it is mild outside

Comfort and efficiency are the strongest reasons. Space heating and air conditioning accounted for 52% of US household energy consumption in 2020^[1], and ENERGY STAR says nearly half of the energy used in a home goes to heating and cooling^[2]. A system that runs better uses less of it.

• Tune-ups: a maintained system is more reliable at the first heat wave or freeze, and problems found in spring cost less to fix than breakdowns in July.
• Ducts: ENERGY STAR says sealing and insulating ducts can improve heating and cooling efficiency by as much as 20%^[2]. Duct testing is ideal shoulder work.
• Installation quality: improper installation can reduce efficiency by up to 30%, according to ENERGY STAR^[2]. Replacement messages should emphasize sizing, commissioning and workmanship, not just equipment brands.
• Safety in fall: more than 400 Americans die each year from unintentional carbon monoxide poisoning not linked to fires, and gas and oil furnaces are among the sources^[4]. A fall heating check with a carbon monoxide test is a legitimate safety message.
• Planning ahead: replacing an aging system on a chosen date beats replacing it on the hottest day of the year with whatever is in stock.

Regional timing

Shoulder seasons arrive at different times across the country, and so does the balance between cooling and heating work. Air conditioning is used by 93% of households in the South and 92% in the Midwest, compared with 73% in the West^[5].

• Hot southern markets: the spring shoulder is short and early, so cooling tune-ups start in late winter; the fall shoulder is longer and good for replacements.
• Midwest and Northeast: two clear shoulders; spring for cooling maintenance and fall for heating checks and replacement planning.
• West: wide variation between coastal and inland areas; plan by your service area's weather, not the region's.
• Heat pump markets: one system does both jobs, so pitch a single maintenance plan with two visits a year.

Refrigerant changes and replacement conversations

The refrigerant transition gives replacement campaigns a factual talking point. EPA's Technology Transitions rule sets a 700 global warming potential limit for refrigerants in new residential and light commercial air conditioning and heat pump systems, with a January 1, 2025 installation compliance date, and exemptions for systems whose components were all made or imported before 2025^[6]. Homeowners with older systems often have questions about what this means for repairs and replacement.

Answer those questions plainly. Explain what refrigerant their current system uses, what repairs are still practical, and what a replacement would involve. Avoid scare tactics; customers who feel pressured go elsewhere, and regulators take a dim view of misleading claims. A calm explainer video or service page on the topic is one of the best shoulder-season assets you can build.

A six-week campaign plan

1. 01

   Week 1: maintenance plan members

   Schedule every member's seasonal visit into the slow weeks before you market to anyone else. Members are your easiest bookings.

2. 02

   Week 1: past customers

   Email past customers not on a plan with a tune-up offer and a clear deadline. Text only those who agreed to receive marketing texts.

3. 03

   Week 2: older systems

   Pull customers whose equipment is past the age where you normally recommend planning a replacement, and invite them to a no-pressure replacement consultation.

4. 04

   Weeks 2–4: neighborhoods

   Door hangers around every install and repair, and mail to subdivisions with clusters of similar-aged homes.

5. 05

   Weeks 2–6: new customers

   Search ads for tune-up and maintenance terms, Google profile posts, and a seasonal offer on your homepage.

6. 06

   Week 6: review

   Record booked tune-ups, plan sign-ups, replacement leads and idle hours, and note what to change next season.

Scripts for the phone and the visit

For technicians, the shoulder visit is a chance to build trust, not to sell hard. Train them to report what they find with photos, explain the system's condition in plain words and leave a written summary. If the system is aging, the technician offers a replacement consultation at a time that suits the customer; the comfort advisor follows up with options, not pressure.

Maintenance plans as the anchor

Every shoulder campaign is easier if a large share of your customers already belong to a maintenance plan. Members expect two visits a year, so you can schedule them into exactly the weeks you need to fill, months in advance. Use each campaign to grow the plan: offer enrollment at every tune-up, explain the benefits in plain words, such as priority scheduling and a reminder before each season, and make renewal automatic with the customer's agreement. Over a few years, the plan turns shoulder marketing from a scramble into a schedule.

Protect the peak

Shoulder campaigns should end before the peak starts. When the first heat wave arrives, stop promoting discounted tune-ups and keep capacity for no-cool calls and replacements. Make sure calls are answered when campaigns and weather overlap; one hot weekend can produce more calls than the office can take, and an unanswered emergency call is usually a lost customer.

Plan how overflow and after-hours calls will be handled before you launch: extra CSR shifts, an answering service, or an AI Employee such as Ava that answers, captures the job details and routes urgent no-heat or no-cool calls to the on-call technician.

Example: filling April at a four-truck company

Example (fictional): Northfield Heating and Air usually has two idle trucks for much of April. In mid-March it schedules all 380 maintenance plan visits into April, emails 2,200 past customers with a tune-up offer, invites 160 customers with older systems to a replacement consultation and hangs door hangers around every job.

By the end of April, idle truck days have fallen sharply, 41 customers have joined the maintenance plan and the comfort advisor has 23 replacement consultations booked into May. The owner moves the campaign a week earlier next year, after noticing that the first warm spell in late April produced repair calls from customers who had not yet booked tune-ups.
