Making a 17,000-product HVAC catalogue feel shoppable
Aircore sells heating and cooling systems online. I worked on the redesign of their Shopify store for two very different buyers: homeowners who need guidance, and contractors who already know what they want.
Role
UX, UI, e-commerce design
Project
Redesign of a live store
Platform
Shopify · desktop and mobile web
Catalogue
17,000+ products
01 — The problem
Specs were getting in the way of buying
Buying HVAC is technical. Before a homeowner can compare prices, they have to make sense of SEER2 ratings, tonnage, refrigerant types and compatibility. Contractors already know the model number, so every extra step slows them down.
17,000+
products, from complete systems to spare parts
23
brands on one A–Z page
110%
price-match guarantee, shown throughout the store
What was broken
Specs first
Product pages read like datasheets
Two audiences
One interface had to guide homeowners and stay fast for contractors
Compatibility
Thermostat, line set and pad came up too late in the purchase
Trust
Guarantees and support info were scattered and easy to miss
02 — The customiser
Customising the system before it goes in the cart
HVAC systems rarely ship as a single box. A condenser needs a matching air handler, and most installs also need a thermostat, line set and pad. This was the main part of my work: a customiser that opens when you add a product, so the full system goes into the cart.
What other stores offered
Before we started building, we looked at how other HVAC stores and brands handled this. Most had no customisation at all: you bought the unit and had to work out the add-ons on your own. The few that did offer options only had one or two fixed bundles.
How it works
The customiser on mobile, from the product page to the cart.
03 — Key decisions
Other changes across the store
Smaller decisions, made with both homeowners and contractors in mind.
01
Three ways to browse
By category, by brand for contractors who always buy Goodman or Daikin, and a guided path for people who aren’t sure what they need.
02
Product pages built for a quick check
The spec table, financing, reviews and related systems are ordered so a contractor can confirm a model quickly and a homeowner can read through the details.
03
Trust signals near the buy button
Free shipping, the 110% price match and US-based support are shown next to purchase decisions instead of only in the footer.
04 — Final screens
The redesigned store
Designed for desktop and mobile web.
Home page, before and after
The old store opened on a wall of contact details and a two-row menu. The new one leads with a single offer, a search bar people can actually find, and the four reasons to buy here.
Product page
Specs, financing and reviews, with the customiser one tap away.
05 — Outcome
Where it ended up
The redesign went live on Shopify, covering the catalogue, product pages, the customiser and checkout.
Who it serves
Homeowners
Guidance and comparison before they look at price
Contractors
Quick access to brands, specs and contractor pricing
Both
The same guarantees and totals, however they found the product
