    I purchased a Mitsubishi mini-split from HVAC Direct. Customer service was great and they helped me pick the correct machine. I am able to braze and have a vacuum pump, so I was able to install this unit myself, but generally this unit should be installed by a proper HVAC guy. It has been in use in my 500 SF detached shop for about 4 years now. It cools nicely in the summer and heats well in the winter and functions flawlessly.

    Quiet and efficient. Cools my great room quickly. It replaced a useless Blue ridge minisplit that never worked. I'm hoping it heats as well.

    My house is split level and my primary bedroom is on the upper floor and just never got cold enough. I was struggling to sleep with the Florida heat keeping the room toasty at night. Bad duct work of my central unit meant opening walls and ceilings to fix things. Alternatively with a 2 inch hole and this beast of a unit I now have a super cold bedroom. I can essentially turn off my main unit at night now to save energy. I'm a huge fan of mini splits especially Mitsubishi! And this unit is super quiet too; you wont even notice it's there.

    We're really enjoying our second ever Mitsubishi split HVAC system. Our first system lasted 15 years and we can only hope our new replacement purchased from HVACDirect.com gives equally good service. The system was received in near perfect condition, and I must tell you that I have never seen such an excellent packing job as your distribution center did! The shipping company you hired was outstanding, too. From the online order placement to receiving the system, the process was far easier than I'd imagined it might be, and I wouldn't hesitate to purchase from your firm again. The only wrinkle in our experience was the challenge of finding a qualified installer who would take on the job at a reasonable cost without also having sold us the hardware. But I was told to be prepared for that by your company salesman, and I appreciated his candor. So far so good, and, hopefully, the system will work flawlessly for many years, and we won't have to burden your company with any additional support. Lastly, it was great to be able to save over a thousand dollars on this project, thanks to HVACDirect.com!
