We provide professional HVAC maintenance services to corporate clients and businesses in Bursa. We service an average of 45 different companies a month, and our invoices range between 6,000 TL and 25,000 TL depending on the scope of the job. We want to set up a satisfaction survey to monitor our service quality and spot where our field teams are falling short.
Last year, we put together a pretty comprehensive 12-question survey and emailed it out after visits, but only 2 out of 45 clients actually responded. People are pressed for time, so nobody bothers with long lists. What questions can we ask that get filled out without annoying the client and actually pinpoint operational bottlenecks? What's the ideal number of questions, and what approach should we take to boost response rates?
