MRCOOL DIY Pre-Charged Line Set Extension Bundle – 16' + 25' for Seamless HVAC Expansion

The MRCOOL DIY Pre-Charged Line Set Extension Bundle offers the flexibility you need to extend your MRCOOL DIY HVAC system while maintaining high efficiency and performance. This kit includes a 16-foot and a 25-foot pre-charged line set, designed for use with 9K, 12K, and 18K DIY air handlers, whether wall-mounted or ceiling cassette. The bundle also comes with a complete set of couplers and 75 feet of control wire, making it an ideal solution for navigating tight spaces or increasing the overall line set distance to meet your system's needs.

Perfect for DIYers requiring additional line length or those with complex installation layouts, this bundle offers simplicity and adaptability for an efficient installation.

Key Features:

16-Foot and 25-Foot Pre-Charged Line Sets

The bundle includes a 16-foot and a 25-foot pre-charged line set, both pre-filled with R-410A refrigerant, ensuring seamless connection and system performance. The pre-charged line sets eliminate the need for professional refrigerant charging, making installation straightforward and DIY-friendly.

  • Flexible Installation: The two different line set lengths provide flexibility, allowing you to navigate through tight or awkward spaces. Whether overcoming obstacles or needing extra length, these line sets are designed for more complex installations.
  • Pre-Charged with R-410A: Both line sets are pre-filled with environmentally friendly R-410A refrigerant, so there's no need for brazing, vacuuming, or refrigerant handling during the installation process.

Compatibility with Multiple Air Handlers

This extension bundle is compatible with 9K, 12K, and 18K MRCOOL DIY air handlers, whether wall-mounted or ceiling cassette models. This makes it a versatile solution for HVAC installations in various room sizes.

Effortless Connection with Couplers

The kit includes couplers to join the 16-foot and 25-foot line sets, extending the total line set length to 41 feet. This is particularly beneficial for MRCOOL DIY 4th Generation or EZPRO single-zone systems, where additional length is necessary.

  • Secure Fit: The couplers ensure a reliable, leak-free connection, maintaining the refrigerant flow between the line sets.
  • Quick Installation: The No-Vac Quick Connect design allows for a simple, fast connection without needing specialized tools or professional help.

75 Feet of Control Wire

Also included is 75 feet of control wire, ensuring that your indoor air handlers can effectively communicate with the outdoor condenser. This wire matches the total line set length, providing smooth system operation.

  • Efficient Communication: The control wire ensures that the air handler and condenser remain in sync, optimizing system performance.
  • Longer Reach: The 75-foot control wire complements the extended line set, making it suitable for larger installations or more complex setups.

Ideal for Tight Spaces or Long Installations

By combining the 16-foot and 25-foot line sets, this bundle allows you to extend the line set distance by 41 feet, ideal for installations where the outdoor condenser is farther away. The split length offers added flexibility when routing through basements, walls, or around obstacles.

Extend a Single-Zone System to 41 Feet

For homeowners with MRCOOL DIY 4th Generation or EZPRO single-zone systems, this extension bundle allows the line set length to be increased to 41 feet. It’s perfect for larger homes or when more installation flexibility is needed.

Solid Kids Sandals, Overpriced Like Most Kids Shoes 🌞
Size: 11 Little Kid, Color: Brown, Size: 11 Little Kid, Color: Brown
My son hasn’t worn these yet since it’s December in Indiana and sandals + snow obviously don’t mix. 😂 So this review is based on first impressions rather than long term wear. That said, these seem wider than a lot of typical kids’ sandals, which I REALLY appreciate since we tend to have wider feet in our family. #hobbitfeet The quality feels pretty decent overall. They’re described as lightweight, and while they’re not insanely lightweight, they do have enough weight to feel semi-sturdy and not flimsy or cheap. I like the style and color, and I think they’ll work well for my son once warmer weather hits. My main complaint is the price. At just under $24 at the time of this review, it feels a little high for kids’ sandals and for what these are. I really feel like $20 MAX would make more sense. Kids shoes are almost always priced like adult shoes, even though they clearly use less material, and that’s hard for me to understand and wrap my mind around. Overall, these seem solid for daily wear, I just wish the price was a bit more reasonable and affordable.

Great basic and timeless design
Size: 12 Little Kid, Color: Brown
These sandals are a great find! They’re super easy to get on and off thanks to the Velcro straps, which is a huge win for little ones learning to be more independent. The fit is adjustable and secure, so they stay in place well during all kinds of play. The cork-style footbed is comfortable and gives good support, and the overall design feels sturdy enough to handle everyday wear. They’re lightweight but still durable, and have held up really well so far. They also have a classic, versatile look that goes with just about everything, perfect for summer outfits. Overall, a reliable, comfortable sandal that’s great for active kids. Would definitely buy again!

Great option for boys or girls
Size: 13 Little Kid, Color: Black, Size: 13 Little Kid, Color: Black
This is really more of a unisex option for a sandal. I have sandals that look like this, and both of my children have worn this style. I ordered these for my daughter, with the plan to pass them down to my son if they're not too worn when she outgrows them. The style is very minimalistic, so it goes with lots of outfits. All the straps are easily adjustable, so you can get a good fit. I would say the length is true to size, but the width is maybe a bit wide. Nevertheless, the adjustable straps really help them fit well. They feel really sturdy and I appreciate that the sole has cushion to it. My daughter has worn these every day since I got them out of the closet and they're holding up well.
