What should I do for a gas odor, carbon monoxide alarm, fire, or smoke?

Leave the area immediately and call 911. For a suspected Long Island gas leak, call National Grid at 1-800-490-0045 or 911 from a safe location. Do not operate switches or phones inside, and do not wait for an HVAC appointment before contacting emergency services.

How quickly can Home+ respond to an HVAC emergency?

There is no standing arrival guarantee. Call intake is available 24/7, and dispatch confirms the current ETA after checking the exact address, technician capacity, traffic, weather, demand, reported symptoms, and equipment capability.

Will the HVAC problem be repaired on the first visit?

A first-visit repair is not guaranteed. Completion depends on the diagnosis, required part, inventory, equipment condition, access, safety, and authorized scope. Ask what the next step will be if a required part is unavailable.

Can a new customer request emergency service or book online?

Yes. You do not need a membership to request service. Call (516) 259-1191 for an urgent request so dispatch can confirm the current response option. For a non-immediate request, use hometsair.com/book to review online appointment options.
