A clogged filter can turn a quick maintenance stop into an afternoon callback. 🌬️

That's why we keep MERV 8 pleated filters on the shelf at every Cosco branch, standard and special sizes both, ready to grab the moment you need them. No mainland shipping wait, no waiting on backorders, just clean filtration stocked locally so your crew keeps moving across Oahu, Maui, Kona, and Kauai.

Need a special size? We can get it custom made for you. Want a higher MERV rating or different filtration? We can special order those too.

In Hawaii's heat and humidity, systems are already working hard. A fresh filter is one less thing to go wrong on the job.

Since 1961, keeping our Hawaii HVAC 'ohana stocked has been our kuleana. Swing by your nearest branch, call 808-845-2234, or check stock at coscohawaii.com.

Before you charge it, prove it's tight. 🔧

HI Nitrogen keeps your line sets clean and your pressure tests honest. Purge, braze, leak-check, and commission systems with dry inert gas that won't let oxidation, moisture, or hidden leaks turn into a callback later. Get it right the first time and protect your margins, your time, and your reputation.

Stocked across all five Cosco branches so you're never waiting on a mainland shipment mid-job. Grab a cylinder, keep the crew moving, and move on to the next ticket with confidence in the work behind you.

Swing by your nearest island branch, call 808-845-2234, or check stock at coscohawaii.com.

Rooftop coil cleaning just got a whole lot easier for our HVAC 'ohana. 🌊

SpeedClean's CoilJet, CoilShot, and dry steam cleaner take the hauling and guesswork out of the job, so you can clean coils faster and protect the fins you're there to fix, not damage.

No more lugging heavy liquid jugs up ladders or into tight attic spaces. The CoilJet runs portable and job-site ready, the CoilShot uses pre-measured tablets with just a garden hose, and the steam cleaner handles the delicate stuff without the risk. Less mess, fewer callbacks, more jobs finished before lunch.

Cosco Hawaii keeps SpeedClean stocked across all five branches so you're never waiting on the mainland for gear that keeps you moving. Call us at 808-845-2234, visit coscohawaii.com, or swing by your nearest branch today.

No more waiting on the mainland for a coil that might not even fit right when it lands. 🌴

Cosco Custom Coils are built to your exact spec: dimensions, circuiting, tube size, and connections, all matched to the job, not forced into it. That means correct fit on the first try, fewer callbacks, and less downtime standing between you and the next job.

Hawaii's salt air and humidity don't play fair with equipment, so every custom coil comes backed by a 5-year coating warranty built for island conditions. Add free estimates and expedited local service, and you've got a faster path to a coil that fits, performs, and holds up.

Need a coil that actually matches your system? Call us at 808-845-2234 or visit coscohawaii.com, and let's get it built.

ZoomLock MAX turns a copper connection into a press-and-go job, leak-tight in seconds and rated up to 700 PSI with Parker's 15-year warranty behind it. For our Hawaii HVAC 'ohana, that means fewer truck rolls, faster completions, and one less fire-safety headache on tight job sites.
