      Trustindex verifies that the original source of the review is Google. Had them install a unit on my 1400 square foot home in roseville.  They did an excellent job not just with pricing but professionalism and cleanliness. When everything was done I couldn’t find a single thing left behind.  The system has been running great for 6 months now and I haven’t needed them back for anything.  5 stars.

     Trustindex verifies that the original source of the review is Google. We got three quotes before calling Cobex Air, and Ilya came in thousands below the big names — and that was for a better system. We've lived in Lincoln for awhile and dealt with plenty of contractors, but this was different. He walked us through exactly why the Daikin unit he recommended was superior to what the other guys were pushing, and the numbers just made sense. Install was clean, fast, and the house has never been more comfortable. Don't waste time with the franchise companies. Cobex is the real deal.

     Trustindex verifies that the original source of the review is Google. Illya Manzyuk with Cobex Air came to my house to evaluate my current air conditioning/heating package unit and give me suggestions to a anew one as well as cost estimates.  I found him very engaging and knowledgeable.  He told me the benefits of a converting to a Heat Pump unit verses the current gas unit I had.  He showed me that a conversion to a Heat Pump unit would save me enough money over a ten year period to pay for itself.  That, along with the Cobex Air's impeccable reputation was enough to sell me.
