Key findings
- 57% of HVAC companies in the study that claimed 24/7 service on their website did not list 24-hour hours on Google for all seven days (95% CI 50%-64%, n = 190).
- In the study, HVAC companies in the highest review-volume group replied on average to 66% of their recent Google reviews, compared with 24% for companies in the lowest review-volume group.
- In the study, the most-reviewed HVAC companies were more likely to mention financing (70% vs 25%), promote a maintenance plan (69% vs 43%) and advertise emergency service (75% vs 46%) than the least-reviewed — an association, not a recipe.
