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 a 25-foot and a 35-foot pre-charged line set, specifically 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 DIYers who require extra length to reach their outdoor unit or want to install their MRCOOL system in complex layouts, this bundle offers flexibility and ease for the perfect installation.

Key Features:

One 25-Foot & One 35-Foot Pre-Charged Line Set

This bundle includes one 25-foot and one 35-foot pre-charged line set, each pre-filled with R-410A refrigerant, ensuring a seamless connection between indoor and outdoor units. These line sets eliminate the need for professional refrigerant charging, simplifying the installation process.

  • Flexible Installation: The combination of 25-foot and 35-foot line sets allows you to route through tight or awkward spaces with ease. Whether you’re dealing with obstacles or need additional length, these line sets offer the flexibility necessary for complex installations.
  • R-410A Pre-Charged: Pre-filled with environmentally friendly R-410A refrigerant, these line sets are ready to install without requiring brazing, vacuuming, or handling refrigerants.

Compatible with Multiple Air Handlers

This extension bundle is compatible with 9K, 12K, and 18K MRCOOL DIY air handlers, whether wall-mounted or ceiling cassette units. Its versatility makes it ideal for different room sizes and setups.

Effortless Connection with Couplers

The kit includes couplers to join the 25-foot and 35-foot line sets, extending the total line set length to 75 feet. This is particularly beneficial for homeowners using MRCOOL DIY 4th Generation or EZPRO single-zone systems.

  • Secure Fit: The couplers provide a reliable, leak-free connection between the line sets, ensuring the refrigerant flow remains intact.
  • Quick Installation: With the No-Vac Quick Connect design, the line sets and couplers can be easily connected without requiring special tools or professional assistance.

75 Feet of Control Wire

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

  • Efficient Communication: Ensures the air handler and outdoor condenser stay in sync, delivering smooth and reliable system performance.
  • Longer Reach: The 75-foot control wire complements the extended line set length for easy installations in larger homes or complex layouts.

Perfect for Tight Spaces or Long Installations

This bundle allows you to extend your line set distance by connecting a 25-foot and a 35-foot section—ideal for installations where the outdoor condenser is farther from the indoor unit. By splitting the line sets into two segments, you can easily navigate through basements, walls, or around obstacles, offering installation flexibility.

No problems after a year and a half
Color: Dogwood & Calming, Size: Medium
Have been regularly buying these for my corgi for about a year and a half. The 2 pack lasts about a month or 2 each time. Pieces break off in small enough pieces that they safely pass through his digestive system. He gnaws each one down to about 1/4 the original size before we take it away and give him a new one. He continues to have regular bowel movements and has a healthy appetite so I can’t imagine any problems arising after so long. I have tried other alternatives and every other similar chew breaks off in larger pieces and didn’t feel comfortable letting him chew/eat them. I noticed there are a few 1 star reviews saying their dogs got sick off these but after a year and a half I have had 0 issues with this product. I guess it depends on the dog and how big of pieces they are swallowing. My dog ingests pieces about the size of a grain of rice so just pay attention and you should be fine.

Long lasting and safer alternative to sticks
Color: Dogwood & Calming, Size: Medium
These are great, very durable, and have lasted a very long time. Much safer for my dogs than the random sticks they find in the yard. They do get shorter with chewing eventually, but they don't break off in little chunks like I've seen with some nylon chews, and they don't splinter like wood. Medium size works well for both my 16 lb Cavalier and my 60 lb Pyrenees/Golden mix. They're both moderate-to-aggressive chewers, though size obviously affects how much damage they can do. I wish you could buy the hemp chew separately because that one is very much a favorite in my house, so after 2 years and 2 purchases, I have barely any left of the remaining hemp chew, but still 2 of the dogwood chews that neither dog is as interested in anymore. I'd love to buy a couple more of just the hemp one.

Your dog will thank you.
Color: Dogwood & Fresh Breath, Size: Large
My dogs loves to chew on these. They make a small mess but not as bad as other chews. They are food for keeping teeth clean.

Nice chew toy
Color: Dogwood Mushroom, Size: Medium, Color: Dogwood Mushroom, Size: Medium
Super durable and puppy loves it. It was a bit hard for her at first but now at 5 months it’s one of her favorite things to gnaw on! It is heavy for the size but seems to be great quality and has given many hours of chew time with minimal wear.
