Working with Mark and his team was a great experience. Supporting a locally owned small business is always preferred, and Mark made the whole process smooth and easy. He explained everything to us very clearly, talked us through options, and offered very fair pricing. He communicated with us consistently throughout the process and updated us on any needed changes, always making sure we had options to choose between. Everything is looking amazing now and working perfectly! Highly recommend choosing Mark's Mini Splits!

I'm so happy to have found Mark! Our three mini splits were overdue for a professional cleaning, and Mark came and took care of them. We can tell that they're working more powerfully and efficiently now, and the unit in our bedroom no longer rattles. We'll be having Mark out again for future maintenance. He is communicative, kind and personable.

I had an excellent experience with Marked Mini Splits installing a mini-split HVAC system in my home. From the very beginning, the communication was clear, professional, and honest. The installer took the time to explain my options, answered all my questions, and helped me choose the right system for my home’s layout and needs. The installation itself was done efficiently and with great attention to detail everything was clean, neatly installed, and tested thoroughly before they left. The system works perfectly and has already made a huge difference in comfort and energy efficiency. If you’re looking for reliable, high-quality HVAC work, I highly recommend Marked Mini Splits.

I’ve called on Mark a few times now to help with installs, and each time I’ve received reliable and knowledgeable service. It’s a relief to have down to earth, hard working people that follow through with the plans, and that’s what Mark has done.

I desperately reached out to Mark last summer and he quickly fit me in. He is not only a fantastic contractor, but an all around amazing human being. He provided great service at a great price. Thank you, Mark. I hope our paths cross again! 💛
