Fresh-air questions, answered

Do you install ERV systems?

No — we do not install. Every kit ships complete, with $200 of technical support included in the price, and a contractor or a confident DIYer does the physical install. We size the system, supply every part, and stay on the phone through the job. Questions before you order? Call 303-775-3139.

What is the difference between an ERV and an HRV?

Both recover heat from the air they exhaust. An HRV stops there. An ERV also transfers moisture between the two air streams, so the house does not go bone-dry in winter or muggy in summer. Every UpgradeAirKit kit is built on a LifeBreath energy-recovery core. Read the full ERV vs HRV comparison.

Which kit size do I need?

Size by port count: one supply port per bedroom or living space, one exhaust port per bathroom, kitchen and laundry. Kits run from 4 to 12 ports. Not sure? Ask for a free planset and we size it from your floor plan, or check the CFM table.

What’s included in a kit?

An ERV kit contains a LifeBreath ERV core, Zehnder ComfoWell supply and exhaust manifolds, ComfoFlex semi-rigid ducting, MERV 6 and MERV 13 filters, room registers and diffusers, Auto Balance Control with boost switches, weather hoods and duct marking tags — plus technical support. Compare every bedroom ERV system kit side by side.

Is the price a project total?

Yes. The listed price covers the equipment for the whole system plus $200 of technical support — not on-site installation labor, which your contractor or you provide. Tax and shipping are calculated at checkout, as the footer on every page says. There is no separate design fee and no sizing charge.

Do I need a permit, and where is the CFM table?

Permits are set by your local building department, not by us — ask them before you order. What they usually want is the design airflow. Our CFM table lists the rated airflow for every kit size, ready to attach to a permit set, and every free planset states the CFM the design is built around.

Can I add filtration for smoke or allergies?

Yes. Every kit already filters with MERV 6 and MERV 13 media at the manifold. For smoke, wildfire season or heavy allergies, add the Scrubber Filter Box, triple packed ($925) — an in-line box carrying a MERV 8 pre-filter, a MERV 15 pleated filter and an activated carbon stage for odors and VOCs.

CLEAN AIR. BALANCED AIR. BETTER LIVING. THAT'S THE UPGRADE.
