Short answer
HVAC is the equipment that heats, cools, and moves air through your home. Most service calls start with a clear description of what changed: temperature, noise, smell, or a system that will not start.
What HVAC covers
Furnaces, air conditioners, heat pumps, air handlers, thermostats, and ducts work together. A problem in one part can look like a different symptom in another.
Simple checks before you book
Confirm the thermostat mode and setpoint, check that the system has power, and replace a dirty filter if you can do so safely. These steps do not replace a diagnosis.
