Frequently Asked Questions About HVAC Services

It is recommended to have your HVAC system serviced at least once a year, ideally before the heating or cooling seasons start. Regular maintenance can help extend your system's life and improve its efficiency.
Symptoms that may indicate that your HVAC system needs repairs include poor indoor air quality, uneven heating or cooling, increased energy bills, and strange noises from the unit.
HVAC systems can be complex and require specialized knowledge and equipment to diagnose and repair. It is recommended to hire a professional HVAC technician to diagnose and repair any issues with your system, as attempting to fix it yourself could potentially cause more damage or even be dangerous.
