MRCOOL DIY Pre-Charged Line Set Extension Bundle – Expand Your HVAC System with Ease

The MRCOOL DIY Pre-Charged Line Set Extension Bundle provides all the flexibility you need to extend your MRCOOL DIY HVAC system while maintaining high performance and efficiency. This kit includes two 35-foot pre-charged line sets, designed for use with 9K, 12K, and 18K DIY air handlers, whether wall-mounted or ceiling cassette. Additionally, the bundle comes with a complete set of couplers and 75 feet of control wire, making it an ideal solution for maneuvering through tight spaces or extending the overall line set distance.

Perfect for DIY enthusiasts who require extra line length to reach their outdoor unit or want to install their MRCOOL system in complex layouts, this bundle offers the flexibility and simplicity to achieve the perfect installation.

Key Features:

Two 35-Foot Pre-Charged Line Sets

The bundle includes two 35-foot pre-charged line sets, each pre-filled with R-410A refrigerant, ensuring a seamless and efficient connection between the indoor and outdoor units. These line sets eliminate the need for professional refrigerant charging, making installation more straightforward and accessible.

  • Flexible Installation: The two sections of 35-foot line sets allow you to easily route the lines through tight or awkward spaces. Whether you're dealing with obstacles or need additional length, these line sets offer the flexibility needed for complex installations.
  • Pre-Charged with R-410A: The line sets come pre-filled with environmentally friendly R-410A refrigerant, so there's no need for brazing, vacuuming, or handling refrigerants during installation.

Compatible with Multiple Air Handlers

This extension bundle works seamlessly with 9K, 12K, and 18K MRCOOL DIY air handlers, whether wall-mounted or ceiling cassette units. This versatility makes it the ideal solution for various room sizes and HVAC system setups.

Effortless Connection with Couplers

The kit includes a set of couplers that join the two 35-foot line sets together, extending the total line set length to up to 75 feet. This is particularly beneficial for homeowners using a MRCOOL DIY 4th Generation or EZPRO single-zone system.

  • Secure Fit: The couplers provide a reliable, leak-free connection between line sets, ensuring the refrigerant flow is not compromised.
  • Quick Installation: The No-Vac Quick Connect design allows for a fast and easy connection without requiring special tools or professional assistance.

75 Feet of Control Wire

The bundle also includes 75 feet of control wire, ensuring efficient communication between the indoor air handlers and the outdoor condenser. The control wire is pre-matched to the length of the line sets, ensuring proper connection and smooth operation.

  • Efficient Communication: The control wire ensures that the air handler and outdoor condenser are in sync, delivering efficient and reliable system performance.
  • Longer Reach: The 75-foot wire complements the extended line set length, allowing for installations in larger homes or more complex layouts.

Perfect for Tight Spaces or Long Installations

The bundle allows you to extend your line set distance by connecting two 35-foot sections—ideal for installations where the outdoor condenser is farther from the indoor unit. By dividing the line sets into two segments, you can easily navigate through tight spaces such as basements, walls, or around obstacles, providing installation flexibility.

Extend a Single-Zone System to 75 Feet

For homeowners with a MRCOOL DIY 4th Generation or EZPRO single-zone system, this extension bundle increases the total line set length to 75 feet. Whether you’re working in larger homes or need more installation flexibility, this kit provides the reach needed for a smooth and hassle-free setup.

Euphy works good as new!
Style: 19 Pack
As soon as I opened the package everything looked the same- pre-filters, filters, main brush, and side brushes. I changed the big brush first;the only issue was the new brush body didn't have the white arrows to help aligning but that didn't affect how the brush worked. I changed filter and pre-filter, and finally the side brushes. When I turned on my "Goophy" and tried to let her run the side brushes were a little too (Goophy's side brushes sounded a little louder). I trimmed the side brushes a little and all was well. Goophy didn't want to run herself but it didn't take long for me to figure out it wasn't the new brushes ;just the operator pushing the wrong button. My Goophy Euphy did what she was supposed to do- vacuum the carpet and tile floor. Goophy Euphy still wanted to take the long way to her charging station which was nothing new and easily corrected. Over all the new brushes and filter restored Goophy Euphy back to when we first used her!

Don't be cheap like me - buy these and save yourself the hassle!
Style: 19 Pack
I made the mistake of going with another, slightly cheaper set of replacement parts for our Eufy RoboVac 11S. I did not heed the cautionary tales which lead me having to find replacement parts for the replacement parts. This brand fits our vacuum perfectly - the corner brushes don't pop off, the filter is the right size and the roller brush gets sufficiently tangled with cat hair so clearly also a good fit. My only concern (and why I only gave four stars) is - surprise! - the corner brushes. Do they stay on? YES! In fact, they is so secure, I had difficulty swapping one out. Here's the peculiarity of the brand - the "whiskers" on the spinner fell out. I found them all over the floor, on different surface types and under various conditions; they were not getting caught on any one thing. Not all at once, but over two or three uses, one of the corner brushes had become devoid of almost two entire spokes! Ironically, the little guy can't seem to pick up his own mess but I digress. Without the whiskers to grasp, removing the part was difficult. I ended up using a small flathead screwdriver for leverage to pop it off. While the other corner brush appeared to have shed some whiskers as well, it was not in need of replacement. Despite the shedding, this will be my first go-to for replacement parts next go round.

Essential!
Style: 19 Pack
After about 2 months of daily cleanings, the side brushes were looking a little ragged on my Eufy 12. The brushes included in this kit did come out a little bent, but as shown on the product page, when I dipped them in hot water they straightened right out. Intrigued, I decided to try that with the original brushes. They cam out looking like new! The only con is that the filters don't look like a perfect fit. The foam seems very minutely smaller than the original and the pleated filter seems slightly thicker.
