The problem with manual quoting for hvac engineers

Sound familiar?

🌡

Complex heat load calculations

Every HVAC quote requires heat loss/gain calculations, system sizing, and duct design. This takes hours manually — and errors lead to undersized or oversized systems.

📄

Proposal formatting

Commercial HVAC clients expect detailed proposals with system specifications, equipment datasheets, and maintenance plans. Building these from scratch is time-consuming and inconsistent.

Regulatory compliance

F-Gas regulations, Part L compliance, MCS certification for heat pumps, and Boiler Plus requirements all need to be referenced correctly in quotes and proposals.

Multiple system options

Clients often want to compare heat pump vs gas boiler, or ducted vs split systems. Producing multiple proposal variants manually doubles or triples quoting time.

What the quoting software does for hvac engineers

Built specifically for hvac engineer quoting — not a generic tool.

Heat load estimation

The AI estimates heating and cooling loads based on building size, construction type, and location — giving a starting point for system sizing.

Equipment specification

Automatically recommends suitable boiler kW output, heat pump capacity, or AC tonnage based on the job description.

F-Gas & MCS compliance notes

Flags relevant regulations including F-Gas handling requirements, MCS certification needs for heat pumps, and Boiler Plus compliance.

Multi-option proposals

Generate comparison proposals showing different system options side by side — e.g. heat pump vs combi boiler — to help clients decide.

Labour and materials split

Full breakdown of equipment costs, consumables, labour time, and commissioning charges.

Professional PDF proposal

Output a professional branded proposal PDF ready to send to residential or commercial clients.
