Service Details

Commercial Emergency HVAC: what matters before you book

Commercial emergency service is about stabilizing the site and reducing downtime. The first call should capture the building type, unit location, access instructions, tenant impact, and whether the space has no heat or no cooling.

No cooling

Cooling loss can affect staff, customers, equipment, and tenant comfort.

No heat

Heating outages need fast triage, especially in occupied or temperature-sensitive spaces.

Leaks or shutdowns

Water, drain, and safety shutdowns need immediate attention before damage spreads.

Access coordination

Roof hatches, keys, tenants, and after-hours security can slow the fix if not planned.

Inspection Focus

What OLU HVAC checks on the visit

  • Business name, site address, and site-contact phone number.
  • Unit location, access notes, roof access, and security instructions.
  • Current symptom, affected area, and whether the site is occupied.
  • Thermostat or control status if known.
  • Temporary next step, repair path, or quote requirement.
