Your outdoor AC unit should be no more than 50 feet from your home. Running refrigerant lines over long distances will degrade performance and energy efficiency. Individual units may have specific requirements for performance and efficiency.

Key Takeaways

• Most AC outdoor units should be less than 50 feet from the indoor unit.
• Manufacturers have specific requirements to meet installation standards.
• Non-compliance could affect your HVAC warranty.

Key Considerations for AC Outdoor Unit Placement

The distance is just one factor considered when choosing the location of an outdoor unit for AC installation in Suffolk County.

A licensed heating and cooling contractor on Long Island will consider:

• The distance between the indoor and outdoor units.
• Drainage requirements for condensate lines.
• Local regulations or HOA guidelines.
• Manufacturer specifications.

As a homeowner, your primary concerns are performance, aesthetics, and practicality. Choosing an experienced HVAC contractor will ensure that your AC outdoor unit is easily accessible, out of the way, and aesthetically integrated with your home exterior.

What Happens if Your Outdoor AC Unit is Too Far Away?

Installing the outdoor unit too far away from your home and the indoor unit can introduce performance and cost problems.

• Longer refrigerant and condensate lines add cost and complexity, increasing your total AC installation bill.
• Cooling capacity and thermal efficiency decrease with a longer line set. Refrigerant loses energy while traveling through copper lines, so your air conditioner will need to run longer or at a higher setting to achieve your desired temperature.
• The compressor in your system uses oil mixed with refrigerant. If the distance is too long, or if there’s a steep vertical rise, the oil will struggle to flow. This can degrade the compressor and reduce its lifespan.
• You will void your manufacturer’s warranty if you exceed the maximum distance and height limitations of the installation manual.

The Bottom Line: Your Outdoor AC Unit is Better When It’s Closer to Your Home

Your outdoor AC unit should be installed as close to your home as possible. This will reduce the length of the refrigerant line, improving overall efficiency. Your system will use less energy. Your compressor will run smoothly when the distance is kept within the manufacturer’s specifications.
