The MRCOOL® Universal Series Central Heat Pump & Air Conditioner System: Quiet, Efficient, and DIY-Friendly Comfort

The MRCOOL® Universal Series Central Heat Pump and Air Conditioner System is a groundbreaking solution in whole-home climate control, delivering exceptional energy efficiency, whisper-quiet performance, and simplified installation compared to traditional central HVAC systems.

Unlike conventional split systems, the Universal Series features a DC inverter compressor that intelligently adjusts output based on real-time demand. It ramps up when needed and scales down during mild weather conditions—maximizing comfort while minimizing energy use and utility bills. This variable-speed operation not only enhances efficiency but also reduces system wear and tear, extending the life of your HVAC investment.

Designed with flexibility in mind, the Universal condenser can pair with many existing air handlers from other brands. However, for optimal performance, it is best matched with a MRCOOL air handler.

The 2–3 Ton MRCOOL Universal System includes a full-sized air handler and a compact, side-discharge condenser that supports 24,000–36,000 BTU capacity—ideal for spaces between 1,100 to 1,550 square feet. This system offers unmatched versatility: the 3-ton condenser can be field-configured to operate as a 2-ton unit using simple dip switch settings.

Installation is quick and hassle-free thanks to MRCOOL's pre-charged Quick Connect line sets (sold separately in lengths up to 50 feet). No vacuuming or refrigerant charging is required, making it a true DIY-friendly solution.

Using the same advanced inverter technology found in MRCOOL mini-splits, this system automatically adjusts its output to maintain consistent indoor temperatures with maximum efficiency and minimal energy waste.

We also sell the MRCOOL Universal 4-5 Ton Central Air Conditioner which can cover 2,200-2,750 square feet.

THE MRCOOL Universal Series Heat Pump can continue heating in temperatures as low As -22. The Universal can deliver 100% cooling capacity at temperatures up to 110 degrees Fahrenheit, 80% heat output down to -4 degrees. The air handler comes with an electrical box assembly, a fan motor, a secondary drain pan, a primary drain pan, and an optional auxiliary heat kit.

No-Vac Quick Connect Line Set

The MRCOOL No-Vac Quick Connect Line Set is one of the biggest advantages of the MRCOOL Universal Series Central Heat and Air Split System. This line set is kink resistant, pre-charged with R410a refrigerant, and uses Quick Connect fittings. 

The quick connect functionality means that the installation of the Universal System saves you hours, and doesn't require any special tools and equipment. 


Features

Quiet - For every 10 Decibels (dBa) a sound is twice as loud-making the Universal 55 dB(a) less than half as loud as the conventional 73 dB(a) condenser.

Easy installation - The Universal® has Flare, Flare-to-Weld, or No-Vac® Quick Connect® line set options and Multi-Position Air Handler installation options (Upflow, Horizontal).

Great product, great company!
Size: 1 Ounce (Pack of 1), Size: 1 Ounce (Pack of 1)
I found some of this years ago and loved it. Ran out, couldn't figure out where to find more then this last Christmas my mother gives me some of the rose salve and I remembered how much I loved the lotion. So as I was looking for more of the rose salve (also AMAZING) I got some of the lotion. It goes on really light feeling, but has some serious softening abilities. I use the salve on my knuckles first then use like a Chick-pea size amount of the lotion overnight and my hands are great the next day, especially considering how much I've been washing my hands and using hand sanitizer these last few weeks. It smells like lemon meringue pie, and is more lightly perfumed than BBB stuff (which I love since I'm prone to headaches). I love CO Bigelow products, have yet to try one I dislike. I use the overnight lip balm in the winter or during colds when my lips crack and dry the most. I use the rose salve for my regular daytime lip balm (stuff is the duct tape of the salve world, no joke!) and for extra relief on any dry skin. Some might argue it's a little expensive for the size you get, but you don't need much of any of them so they last forever. I still have half a tube of rose salve lip balm from Christmas and I use it every day, several times. They all smell good, they all feel really clean on, they do what they're supposed to without adding products (like glycerin) that will cause further dryness or chapping. Thank you so much, CO Bigelow for making so many quality products and being so consistent with the quality for so long. Fan for life here!

Consistent Quality
Size: 1 Ounce (Pack of 1)
I've used this off and on for years and it's my favorite. I'm extremely picky with things I slather on my skin, and usually make my own from balms, oils, lotions etc. from scratch..with herbs infused for deep healing of skin and muscles. I didn't make enough this year so had to turn to store-bought. I'm not a fan of too many ingredients, and this lotion has more than I prefer, but it works really well if I need it. Winter skin, hands after doing dishes, etc..this lotion fixes it. It goes on, absorbs fast and feels light. The smell is great too. It's not overpowering and doesn't give me a headache like 99% of scented things do. I love this stuff, only wish it was cheaper. It's great, but the ingredient list isn't very good; it doesn't cost a fortune to make this.

Best hand lotion I have ever used
Size: 3 Ounce (Pack of 1)
This lotion is great. Smells lemon fresh. It doesn’t leave your hands greasy or like they have a layer of lotion on them. Goes right into skin no sticky residue.

MAKES HANDS SOFT AND SMELLS GREAT, BUT TOO SMALL!!
Size: 1 Ounce (Pack of 1)
Purchased BIgelow lotions and soaps. Love the lemon scent. I purchased this, thinking I was getting a larger tube. Not happy with the size and price of this. I will shop better next time--and Bigelow loses a star. Nice product!

Perfect hand cream
Size: 3 Ounce (Pack of 1)
I first bought the small tube that didn't last long. Then I purchased the larger tube so I wouldn't run out. I love the lemon scent and the cream is perfect to keep my hands soft and moisturized. You can't go wrong with this product. I highly recommend it.
