System not working
When to request HVAC repair
Describe the change in performance so a technician can assess the next step.
Write down the change
Note when the issue started, the thermostat reading, whether the system runs and which rooms are affected. These observations help frame the service conversation.
Explain what you have noticed
Mention unusual cycling, new noises or a difference between the set temperature and room temperature. Symptoms alone do not establish which component needs repair.
Choose the next step
Call for urgent service availability. For a routine request, include a short description and your town. Do not open equipment or attempt electrical or refrigerant repairs.
