What should I ask an HVAC company before replacing a system?
Ask for a written estimate covering equipment, labor, permits, disposal, warranty terms, and any ductwork changes. A second opinion can help compare replacement options.
When does an HVAC problem require emergency service?
Turn off the system and seek urgent help for gas odors, suspected carbon-monoxide exposure, electrical burning smells, or severe water leaks. A system that is simply underperforming can usually be scheduled as routine service.

Many homeowners schedule heating and cooling tune-ups annually, typically before each major season. Maintenance agreements are available from some local providers.
Do HVAC installations in North Carolina require permits?
