After-sales service is what differentiates a good installer from an excellent one. An HVAC system should be checked after a few days of use to make sure it is working properly.
In addition, users may have questions about the use of controls, saving modes or basic maintenance. Quick and human contact makes the difference in the customer experience.
Having an installer available for assistance, preventive maintenance or troubleshooting provides peace of mind and extends the life of the equipment.
The relationship does not end with the installation: the subsequent technical support is part of the service.
