Service overview
What this service covers
Evaluate building loads and system requirements to support correctly sized HVAC replacement or conversion planning. For homes, businesses, and managed properties, the useful scope depends on the installed equipment and the conditions present at the property. Planning and documentation work should connect equipment identity, building load, compatible system combinations, installation conditions, efficiency goals, and the records required for a sound decision.
The consultation turns site conditions and operating goals into a documented next step rather than a generic equipment recommendation. Useful inputs include model data, building use, comfort patterns, energy or maintenance history, access constraints, budget timing, and any incentive or compliance records that affect the decision.
- Use building and design-condition inputs rather than selecting capacity only from the existing equipment nameplate
- Confirm the existing equipment, building use, comfort concern, and project goal
- Collect model numbers, capacities, site conditions, and available operating or energy information
- Review compatibility, sizing, electrical or fuel readiness, and installation constraints
- Separate verified eligibility or certificate facts from preliminary estimates
- Document recommended next steps, open decisions, and records needed before installation
- Separate verified site and equipment facts from assumptions that need additional investigation
- Deliver a practical decision path with dependencies, options, and recommended next records or measurements

What information helps with a HVAC load calculation and equipment sizing request?
Share the property type, equipment model if available, current symptoms or project goal, photos, access details, and preferred timing. This helps Green Flow route the request and prepare the right next step.
Does HVAC load calculation and equipment sizing start with an on-site assessment?
The appropriate first step depends on the equipment and request. Green Flow may begin with equipment identification and an on-site review before confirming repair, maintenance, installation, or replacement scope.
Can Green Flow coordinate HVAC load calculation and equipment sizing for occupied properties?
Access, occupants, tenant impact, operating schedules, and site constraints can be discussed during planning so the approved work can be coordinated appropriately.
