FAQ

Q1: What is an HVAC Line Set and what is its function?

An HVAC line set is a pair of copper tubes connecting the outdoor unit (condenser/heat pump) to the indoor unit (air handler). Its function is to circulate refrigerant to transfer heat. It consists of:

• Suction Line (Large): Insulated, carries cool, low-pressure gas back to the compressor.

• Liquid Line (Small): Less insulated, carries warm, high-pressure liquid to the indoor unit.

Q2: What are the different types of HVAC Line Sets?

Main types are defined by material and build:

• ACR Copper: Industry standard, factory-sealed with nitrogen to prevent contamination.

• Soft vs. Hard Drawn Copper: Soft copper is bendable for easy installation; hard drawn is for straight runs.

• Pre-insulated Line Sets: Most common for homes, with foam insulation (e.g., Armaflex) pre-installed on the suction line.

Q3: How do I choose the correct line set size?

Size is critical and is based on your system’s tonnage (capacity) and the distance between units.

Common Residential Sizes:

• 1.5-2 Ton: 3/8" liquid line, 3/4" suction line.
• 3-4 Ton: 1/2" liquid line, 7/8" suction line.
• 5 Ton: 5/8" liquid line, 1-1/8" suction line.

Always consult a licensed technician or the manufacturer's manual. Incorrect sizing reduces efficiency and can cause damage.

Q4: Can I reuse an existing line set?

Generally not recommended. Reasons include:

• Contamination: Old lines may contain debris or moisture that harms the new compressor.

• Compatibility: Newer systems (R-410A/R-32) run at higher pressures than older ones (R-22).

• Leak Risk: Existing joints and tubing may be fatigued.

Best practice is to install a new line set to ensure performance and protect your warranty.

Q5: What is the purpose of the insulation on the suction line?

The insulation serves two key purposes:

1. Prevents Energy Loss: Keeps the cold refrigerant from absorbing outside heat, maintaining efficiency.
2. Stops Condensation: Keeps the pipe surface above the dew point to prevent water drip, which can cause mold or damage.

Q6: Should I search for "HVAC supply store near me" or "HVAC installation service"?

Always search for a licensed "HVAC installation service" or "HVAC contractor."

• Why a Contractor? Installation requires specialized skills (brazing, pressure testing, evacuation) and is not DIY.
• Supply Store Role: They mainly sell to professionals. Your contractor will source the correct line set for the job.

Q7: What are the consequences of a leaking line set?

A refrigerant leak is a serious problem, causing:

• Reduced cooling/heating capacity.
• Higher energy bills.
• Compressor failure due to overheating and lack of lubrication.
• Environmental harm from released greenhouse gases.

If you suspect a leak (e.g., ice on coils, hissing sounds), contact an HVAC professional immediately for repair.
