If you're an HVAC contractor in Corona, CA, you already know that having the right parts on hand can make or break your schedule. Delays in sourcing components can result in missed appointments and unhappy clients.

At West Coast Copper & Supply, we help local HVAC professionals stay ready for any job. Here are five essential HVAC parts that should always be in your truck—or ready for same-day pickup at our Corona supply store.

1. Copper Linesets

Your cooling systems are only as good as the copper lines connecting them. We stock both pre-insulated and bare copper linesets in a range of sizes to fit every type of residential and commercial HVAC application.

2. Flexible Ducting

Flexible ducting is a must for installations in tight spaces or attic crawlspaces. Our inventory includes various sizes and R-values to meet California Title 24 energy code compliance.

3. Sheet Metal Fittings

From custom elbows and transitions to off-the-shelf options, having the right sheet metal fittings speeds up installations and ensures a quality finish. We fabricate and stock a wide variety of galvanized and aluminum fittings.

4. HVAC Fasteners and Sealants

Don’t let a missing screw or runny mastic slow you down. Our store carries a full range of fasteners, zip screws, foil tapes, duct sealants, and other install-day essentials.

5. Thermostats and Electrical Components

Whether it’s a basic programmable thermostat or a smart model, we have control options for every system. You'll also find fuses, disconnects, contactors, and wire nuts to complete the job.
