The HAVEN Method

Drew Tozer created the HAVEN method to show the path for any house to become a feel-good home.

Heat pumps deliver remarkable results if they're sized and installed properly. Foundry Heat Pumps uses its proprietary HAVEN method to find the right heat pump for every house.

The path to a feel-good home: the HAVEN method.

Traditional HVAC companies rely on quick & easy sales without addressing underlying issues in the house.

Foundry Heat Pumps follows its proprietary HAVEN method to solve homeowner problems with right-sized heat pumps.

1. Assess

heating load

The amount of heating that the house needs. How does your house perform in real-world?

air leakage

Air leakage is the biggest source of heat loss and a significant cause of comfort complaints. How leaky is your house?

value mindset

To pick the right project, it's important to focus on the benefits that you'll receive by solving underlying problems. How much is home comfort and clean air worth?

2. Plan.

environmental control

Right-sized HVAC is required to control the environment. What equipment is needed to improve your home?

necessary infrastructure

HVAC equipment is limited by the systems in the house, including ductwork and electrical. Do you need to upgrade infrastructure or does the right HVAC already fit?

Hear from feel-good homeowners...
