The MRCOOL® Universal® Series 36K DC Inverter Heat Pump Condenser is designed to deliver dependable, high-efficiency heating and cooling—even in the most extreme weather conditions. Whether you're facing sweltering summer heat or freezing winter temperatures, this unit ensures steady, year-round comfort. With an impressive 18 SEER2 efficiency rating, it offers substantial energy savings without compromising performance, making it an ideal replacement for outdated, energy-hungry systems.
Engineered for flexibility and convenience, the 36K Universal® condenser features a compact footprint that allows for installation in space-constrained areas. Its smaller size makes it an excellent fit for homes with limited outdoor clearance while still delivering powerful, whole-home comfort. Installation is quick and hassle-free—especially when paired with the optional MRCOOL® NO-VAC® Quick Connect® line set (sold separately). This innovative, pre-charged line set eliminates the need for traditional vacuuming, flaring, or refrigerant handling, reducing installation time, labor costs, and complexity. At the heart of the system is advanced DC inverter technology, which allows the compressor to continuously modulate output based on your home’s real-time temperature demands. Unlike traditional systems that cycle on and off, this inverter-driven condenser maintains more consistent temperatures, reduces power consumption, minimizes component wear, and keeps noise levels to a minimum. Whether you're upgrading an aging system or installing a new HVAC solution, the MRCOOL® Universal® Series 36K Heat Pump Condenser offers a winning combination of efficiency, performance, and quiet operation. To ensure long-lasting confidence, it’s backed by a 10-year parts warranty and a 2-year limited labor warranty.

Here is my absolutely fantastic, excellent review for the business Home Outlet Direct. After looking for months, I found this business. They were kind. This is a great company to buy from albeit not always cheap but good prices overall. However, I find all the charges for this nuts as the damn thing don’t work at all.
My review of the MrCool 24k btu ECM air handler:
I was and am very frustrated with this purchase. It took me months to get this in. I went through 3 line sets. I finally got all lines in right no leaks. All electrical correct. I plugged in their Wi-Fi thermostat and all seemed great! I began registering the thermostat etc. ….then nothing. It shut down. Bricked. all of it shut off. Completely. Bricked . Now, all I have is the Goodman furnace I put in the previous year. MrCool products are not cool. Very expensive and they don’t work at all. Never buying these products again. Spent thousands altogether to run this and it doesn’t do anything. Never buy Mr Cool BS products!
I ordered a HVAC system and it arrived in a timely manner and with no apparent issues. I thought the system was defective once installed but it was the installers fault who wired it wrong. My only issue would be the fee (30% I believe) to return a defective item within the 30 day return policy. If it is defective the customer shouldn't have to pay a fee to return an item that is not operating as designed. Other than that this is a good company.
Installed my own central HP system. It was a bit of work but nothing beyond a person with basic mechanical and electrical skills. It took me a while because I had to remove the existing electric forced air furnace from a pretty tight place. Some custom sheet metal work and a bit of custom electrical too. Worked perfectly when powered up and I actually like the thermostat provided, although I wish it was clearer how to set up a temperature set-back schedule. Pre-charged refrigerant piping was something new and I liked that too. The best thing is that my electric utility forked out $4,000 and that paid for the unit!
Installed with ceiling cassettes... Quiet and keeping us cool so far !
Very good customer service will be buying from them again
