Quote conversion statistics
Quote follow-up is the single highest-ROI activity for most HVAC businesses — the gap between no follow-up and a structured sequence is enormous.

Google reviews — what the data says
Reviews are the #1 trust signal for HVAC customers. The gap between a business with 12 reviews and one with 80+ is enormous in local search visibility and click-through rate.
| Metric | Benchmark | Implication |
|---|---|---|
| Homeowners who check reviews before hiring HVAC | 89% | Reviews are not optional — they are the decision |
| Customers who leave a review when asked directly | 68% | Most happy customers just need to be asked |
| Review count to dominate local HVAC search | 50+ at 4.5★ | Wins majority of local search clicks over competitors |
| Revenue lift from a 1-star rating increase | 5–9% | Reviews have a direct measurable revenue impact |
| Optimal time to request a review | Same day | Within 2-4 hours of job completion, while relief is fresh |
Seasonal demand patterns
Understanding HVAC's demand curve is essential for timing follow-ups, maintenance reminders, and marketing spend correctly.

Industry benchmarks suggest 25-35% of HVAC quotes convert without follow-up. With a structured 3-message follow-up sequence across 3 weeks, conversion rates rise to 45-55% for well-run businesses. System replacement quotes respond particularly well to follow-up that addresses financing and timing concerns.
How many Google reviews does an HVAC company need?
50+ reviews at 4.5 stars or above consistently wins the majority of local search clicks in the HVAC category. 89% of homeowners check reviews before hiring, making review volume and recency a critical competitive factor. Businesses that ask after every completed job typically reach 50 reviews within 6 months.
What is the average HVAC business profit margin?
HVAC businesses typically operate at 15-25% net profit margins. Service and maintenance contracts sit at the higher end of this range. Installation and replacement jobs tend to have lower margins due to equipment costs but generate the highest revenue per job. Businesses with strong recurring maintenance contract bases consistently outperform on overall margin.
What is the best time to send HVAC maintenance reminders?
Late February to early March for spring AC servicing reminders (before booking demand peaks in April–May), and late August to early September for autumn heating system reminders. Sending these reminders 6-8 weeks before peak season, when customers aren't yet panicking, yields the highest booking conversion rates.
How often should HVAC filters be changed?
Standard 1-inch filters: every 30-90 days. Thicker 4-5 inch media filters: every 6-12 months. Homes with pets or allergy sufferers should change more frequently. A filter change reminder text sent to existing customers 3 months after a service call is one of the easiest and most appreciated communication touchpoints in the HVAC business.
