How to Upsell Indoor Air Quality Services to HVAC Customers
The short version
IAQ products — whole-home purifiers, UV lights, humidifiers, dehumidifiers — are the highest-margin HVAC upsell at 50-65% gross margin. Pitched during a tune-up referencing the dirty filter: 25-40% close rate. A 30-day follow-up converts another 10-15%.
Every tune-up puts a tech next to a dirty filter. That filter is the visual evidence for the IAQ conversation.
"Your filter caught a lot of debris. The smaller particles — pollen, pet dander, dust mites — pass through. A whole-home purifier catches those. About $500-2,000 installed."
Under 30 seconds. Reference what they can see.
Follow-up at 30 days: "Allergy season's starting — want to move forward on the purifier?"
Trikkl for HVAC schedules the 30-day follow-up when the tech flags an IAQ mention. At $15/month.
