New home construction heating, ventilation, air-conditioning, system design and installation is the largest part of our business.
All of our new home HVAC jobs include a complete heat loss calculation and a computer deigned and generated equipment selection and duct design for each project.
It is important to have a consultation in our showroom with the home builder or home owner to discuss the different options available and to look at product warrantys and possible optional warranty extensions.
The first step for a new home HVAC installation is the heating mark-out which consists of a site visit from one of our foreman’s to mark all holes (in top/bottom plates, roof top, outside walls of home etc.) in the home to be cut by the framer only.
When this has been completed by the framer our next step is to send the installation crew in for the HVAC stack installation, this includes all piping/ductwork to second floor, all dryer venting, kitchen venting, exhaust venting installed in main/second floors, bathroom exhaust fans to be installed and an HRV system rough-in for all laundry, kitchen, washroom areas. Upon completion of this you would call for your HVAC stack inspection (if using spray foam please make sure all Return air has had Roxul or drywall installed at the end of every joist header.)At this time your gas fireplace would be installed.
The 3rd step in the process of installing your HVAC system would be the furnace/ductwork installation, this will be done after your basement concrete has been poured. Please note that if the basement is being developed after framing is completed you will need to contact us and have us complete the basement development at this time. When we are 100% completed you will then call for your HVAC concealed ductwork inspection (only applies for basement development or basement suite). All ductwork must be inspected before it can be covered with drywall.
The final step in the new home HVAC process is the heat final which consists of installation of all floor registers, toe kick boxes, return air grills, exhaust fans, thermostats, HRV controls range venting and humidifiers. Please note that upon completion the HVAC final, inspection may be called.
The Northstar exclusive furnace and ductwork cleaning is done at this time (if requested) to properly clean the furnace and ductwork of construction dust and debris to avoid any warranty issues later and to ensure you or your customer is moving into a clean air environment.
During all phases of our HVAC installation we have a quality control person checking all stages of the work done to ensure it is at our highest standards.
