ProMax replaced old furnace and air-conditioning unit with a new 4 head mini-split system. Slava did initial evaluation and estimate, he was very knowledgeable, experienced and was spot on on how linesets and other communications should be routed. Installation took about 2 days and was very clean and professional. I will highly recommend for any HVAC needs.
Details: Replace an existing A/C unit • Split system • I already have the A/C unit • As recommended by the professional • Ground floor • 1,000 - 2,000 sq ft • Two stories • Townhouse

Max was punctual, professional, and patient during his visit to repair my Daikin units. His expertise with Daikin units made his diagnostic process very thorough and he found the root cause of what my 3 previous HVAC technician couldn't find. Thank you Max for taking care of a consistent headache that I had!
