Window was 9-10am and they showed up at 9am! Timing was great and the diagnostic was thorough and efficient. No upsell, just what needed attention. I’ll be calling back when I need service.

Called them on Labor Day bc the drain pipe was leaking. They were very responsive in spite of the holiday and were able to get to the property quickly. They were communicative and very easy to work with. They have a full report on the overall health of the system. They’ll go the extra mile for their clients. Highly recommend them

Called Modern Air, and they came out right away to diagnose and fix the problem which was a huge help in this blistering heat! Robert was awesome! He walked us through everything, then got to work immediately. Now our system is blowing super cold again. What a relief!!! We would strongly recommend Modern Air to anyone.

Modern air systems replaced 2 units at my house. Not only did they give the best price, the service was first class. The owner came to inspect work and he was first class. Go with modern air!!!
