It is recommended that the decision to install a geothermal heating and cooling system (vs. a propane or gas fired furnace with a conventional outdoor AC unit) be made early in the design phase of the construction project. Among other efficiencies, this will facilitate the proper preparation of the HVAC permit package and will avoid the need for additional time and expense later to make modifications to a design that was originally conceived using a furnace / AC unit style system.
The architectural drawings will evolve from discussions between the design firm and the clients. The mechanical aspects of the new home design will be determined by the size of the home and an evaluation of the client’s requirements. Quantum Geothermal offers design and consultation services and assistance with the preparation of the HVAC permit package. The HVAC design will be confirmed once a set of heat loss / heat gain calculations are prepared. Again, Quantum Geothermal can provide the services of a BCIN certified designer (familiar with the requirements of geothermal systems) to assist with this aspect of the overall design.
Alternatively, your architect or builder may have a preferred HVAC design company to work with and in this scenario Quantum Geothermal will provide all the necessary specifications for the heat pumps and work cooperatively with the designated HVAC design firm.
A review of the preliminary site plan and an opportunity to offer recommendations concerning the site plan approval process can add opportunities to streamline the approval and permit processes.
