One or more zones are warm
Identify which tenant areas are affected and whether the fan, outdoor section or rooftop unit appears to be running.

Cooling repair signals
When a business cooling problem needs professional diagnosis
The symptom can involve the cooling equipment, controls, airflow, condensate, refrigeration circuit or the building. It helps define the information dispatch needs and the first diagnostic steps.
Cooling starts and stops repeatedly
Short cycling can involve controls, safeties, airflow, temperature limits, electrical conditions or equipment condition.
A control shows an alarm
Share the exact thermostat, rooftop-unit, ductless-system or building-control message when requesting service.
Water appears near equipment
Describe the location and extent of the water. Condensate drainage, coil conditions, airflow or another building source may need review.
Humidity or airflow is uneven
Zone controls, dampers, blowers, filters, outdoor air and operating schedules may need review alongside the cooling equipment.
The same cooling problem returns
Provide prior findings and repairs so the next visit can distinguish a repeated fault from a broader planning issue.
Diagnostic scope
Commercial cooling systems and conditions to confirm
The supported work depends on equipment, size, refrigerant, controls, application, access and safe operating conditions. These are common checkpoints, not a promise that every system or component is supported.
Home+ focuses on residential and light-commercial HVAC. Large industrial, process, chiller, cooling-tower, specialty-control or unsupported equipment may require another contractor. Dispatch reviews the nameplate and site requirements before confirming a visit.

Commercial service process
A clearer handoff for owners and property teams
-
01
Describe the affected space
Identify the warm or humid zones, operating symptoms, building schedule and any immediate access or safety concerns.
-
02
Confirm equipment and access
Share the nameplate, controls, site contact and roof or mechanical-room requirements.
-
03
Evaluate the operating fault
The technician documents findings observable within the supported equipment and approved visit scope.
-
04
Review the written option
Repair, maintenance or replacement work proceeds only after scope and price are presented for approval.
Equipment and building context
Commercial cooling is more than the compressor
Controls, zones, airflow, outdoor air, condensate, humidity, operating hours and access can all shape the diagnosis and the practical service plan.
Packaged rooftop cooling
Cooling operation may involve safeties, refrigeration components, airflow, economizer operation, condensate and zone controls.
Split and ductless systems
Indoor and outdoor equipment, line-set conditions, condensate routing, controls and application help determine whether the system fits the light-commercial scope.
Tenant and operating hours
Affected zones, occupied periods, internal loads and shutdown constraints should be documented before timing is confirmed.
Repair versus replacement
The decision should compare the current fault and repair history with refrigerant, parts and the complete installed replacement assumptions.

Frequently asked questions
Commercial air-conditioning service questions
What commercial air-conditioning equipment can Home+ evaluate?+
Home+ focuses on residential and light-commercial HVAC. Depending on the confirmed equipment and site, the team may evaluate packaged rooftop cooling, supported split systems, heat pumps or ductless systems. Share the nameplate, capacity, voltage, controls and access details so dispatch can verify capability before scheduling.
What should I send when requesting commercial AC service?+
Provide the property address, affected tenant or zone, equipment make and model, thermostat or control message, symptoms, operating hours and access instructions. Photos of the nameplate and visible condition are useful when they can be obtained safely.
Can Home+ service a commercial rooftop unit that is not cooling?+
For packaged rooftop equipment within the confirmed scope, a diagnostic visit may review the cooling call, controls, safeties, airflow, condensate, accessible electrical components and refrigeration operating conditions. The exact work depends on the unit and approved visit scope.
Do you service commercial split or ductless AC systems?+
Some light-commercial split and ductless equipment may fit the team's scope, but equipment type, capacity, refrigerant, controls, application and site conditions must be confirmed first. Large, industrial, process, specialty-control or unsupported systems may require another contractor.
Is after-hours commercial AC service available?+
Call to describe the affected space, equipment and access requirements. Current appointment and after-hours availability depends on call volume, technician availability, location, weather, roof or building access, parts and the work required.
Should a commercial AC system be repaired or replaced?+
The decision depends on the diagnosis, equipment age and condition, repair history, refrigerant and parts availability, efficiency, comfort or humidity needs and the complete installed replacement scope. Home+ can document the current finding and present an applicable option before work is approved.
Can commercial AC maintenance be scheduled with Home+?+
Potentially. Start with an equipment inventory and the building schedule. Home+ will confirm which equipment is supported and whether a one-time maintenance visit or a Business+ recurring plan fits the site and current availability.
