25LB R449A — best price for commercial jobs
Ordered the 25LB R-449A HVAC PRIME refrigerant gas for a walk-in cooler retrofit in Tampa. Cylinder arrived sealed, properly labeled, and shipped from their Florida warehouse in 3 business days. Pulled vacuum, charged the system, and pressures matched spec right away. At $380 this beat every local supplier I quoted. Will reorder from hvac-prime.com for our next R449A job.
30LB R134A for auto A/C — fast shipping
Bought the 30LB R-134A HVAC PRIME refrigerant for our shop's automotive A/C work. Virgin gas, clean cylinder with no dents, and checkout was straightforward. Delivered to Georgia in 4 days with tracking the whole way. At $310 it was significantly cheaper than our old wholesaler. Customer cars are blowing cold again — HVAC PRIME is now our go-to for R134A.
R32 virgin refrigerant — split system install
Picked up R32 refrigerant from HVAC PRIME for a new mini-split install. High purity, factory-sealed cylinder, and SDS paperwork included in the box. System charged perfectly on the first pass. I've ordered R404A and R32 from hvac-prime.com twice now — always reliable for commercial and residential HVAC work at fair wholesale prices.
30LB R22 — hard to find, great service
Found the 30LB R-22 HVAC PRIME refrigerant gas online when local suppliers were out of stock. Cylinder was authentic, DOT labeled, and arrived well-packaged with no leaks. Used it on a legacy RTU repair — system is running strong. HVAC PRIME shipped with tracking updates every step. Worth every penny for R22 when you can still get virgin gas.
R404A for reach-in freezers — bulk order win
Ordered R404A refrigerant for three reach-in freezer repairs at a restaurant chain. All cylinders virgin, sealed, and priced better than our regional distributor. Free shipping on the order over $150 was a nice bonus. Support answered my pre-sale questions about compatibility quickly. HVAC PRIME is now on our approved vendor list for all refrigerant gas.
25LB R449A + gauges combo order
Placed a combined order for 25LB R-449A refrigerant and an A/C manifold gauge set. Everything arrived from the Lake Worth warehouse in one shipment, well crated with no damage. Refrigerant purity tested fine on my scale and the gauges calibrated accurately. Excellent experience — hvac-prime.com had the largest selection of refrigerants at discounted prices I found online.
30LB R134A for fleet A/C service
We service a fleet of delivery vans and buy 30LB R-134A cylinders from HVAC PRIME monthly. Consistent quality, fair $310 pricing, and orders always ship within 2 days from Florida. Cylinders are always full weight and properly labeled for EPA compliance. Better than our old supplier and customer service actually responds to emails. Highly recommend for automotive A/C pros.
First order — R32 for heat pump conversion
Was skeptical ordering refrigerant online but the R32 from HVAC PRIME showed up in 2 days, factory sealed with full documentation. Used it on a heat pump conversion — subcooling and superheat hit target on the first adjustment. Checkout was simple and prices beat my local supply house. Already browsing hvac-prime.com for R404A on the next job.
Commercial refrigeration — R404A restock
Restocked R404A for our supermarket refrigeration maintenance contract. HVAC PRIME shipped multiple cylinders with lift-gate delivery to our loading dock in Orlando. Every tank weighed in correctly and passed our purity check. Fantastic service from order to delivery — these guys know the refrigerant business.
Holiday rush — R449A and R134A bulk buy
Ordered two 25LB R-449A cylinders and a 30LB R134A before our busy season. Everything arrived before the deadline, cylinders intact, and the site was easy to navigate. Prices were the most competitive I found for virgin HVAC PRIME refrigerant gas. Will definitely shop HVAC PRIME again for all our refrigerant needs.
HVAC contractor — regular R22 and R32 orders
We run a small HVAC crew and buy 30LB R22, R32, and R404A from HVAC PRIME regularly. Last order was two R22 cylinders and one R32 — all showed up in 3 days with tracking. Better pricing than our old supplier and support actually picks up the phone. Highly recommend for pros and homeowners who need virgin refrigerant gas.
Ice machine repair — R404A and R449A combo
Got R404A for an ice machine repair and added a 25LB R-449A cylinder for an upcoming cooler conversion. Both virgin refrigerants arrived on time, well packaged with SDS sheets. Systems charged perfectly and customers happy. HVAC PRIME had everything in one place with free shipping on orders over $150. Honest company with quality refrigerant gas — couldn't ask for more.
