Why this part

Why the line set matters

The line set is the pair of insulated copper lines carrying refrigerant between the outdoor and indoor units. Get it wrong and the equipment never performs, however good it is.

Diameter is not a preference. Each system specifies a liquid and suction line size. Undersized suction line starves the compressor; oversized liquid line upsets the metering. The sizes are on the specifications panel of every condenser we sell.
Reusing the old set is a false economy. Old R-410A line sets carry oil residue that is not compatible with the newer refrigerants, and a set that has been open to the air holds moisture. Flushing is possible; a new set is cleaner and cheaper than the callback.
Length changes the charge. Equipment ships charged for a tested length — usually around ten to fifteen feet. Past that, your installer adds refrigerant per foot. Buy the length you need rather than coiling forty feet of surplus behind the unit.
Insulation is not optional in a hot attic. Uninsulated or thinly insulated suction line sweats, drips onto ceilings, and costs capacity every foot of the run.

How buying direct works — the whole process, start to finish 6 steps

You are buying the equipment from us and the labour from an installer you choose. Two numbers instead of one bundled quote — which is the point, but it does mean you are the one connecting them. Here is the whole sequence.

Order the equipment. The price on this page is what you pay us. Nothing about installation is included in it, and nothing is added later.
Line up your installer before it ships. This is the step people skip, and it is the one that causes trouble — equipment sitting in a garage while you ring round for someone free. You need a licensed HVAC professional; opening a refrigerant circuit requires EPA certification. Ask specifically what they charge to install customer-supplied equipment. How to find one.
It ships crated on a freight truck. Orders typically ship within 3–7 business days. A complete system travels as two crates — condenser and air handler — which can arrive on different days. Delivery is to your address on a liftgate truck for one flat price, with nothing to choose at checkout. What delivery costs.
The carrier calls to book a delivery window. That appointment is when your equipment arrives — not the ship date. Answer the call; an unanswered one is the most common cause of a delay.
Inspect it before you sign. Two minutes at the tail of the truck decide whether a damage claim works. Note any damage on the delivery receipt specifically, not just "damaged", and photograph it before it comes off the truck. What to check.
Your installer fits it, then register the warranty. Line set, disconnect, whip, thermostat and equipment pad are not included — your installer supplies those. Registering within 60 days of installation takes about four minutes and extends parts coverage from five years to ten. Warranty terms.
