Eco Fresh HVAC- LA (dba HVACnerd)

John and his crew turned our boggy lair into a winter wonderland. Excellent service and super knowledgeable. Will definitely contact again for any HVAC needs.

I met John several years ago when I was getting estimates to replace my HVAC system. I was impressed by his HVAC knowledge and no pressure and helpful style so I kept his business card for future reference. This summer, during the hottest heat wave, my AC gasped its last cool breath, so when that happens, "Who you gonna call"? Well, John Mattson of course! He not only gave me the best price out of 4 HVAC contractors but included several extras that nobody else did. He called back to make sure everything was running smoothly and came in to adjust a return air grill which was making a little noise. I highly recommend John and will definitely call him for any future HVAC needs. ***** OVERDUE UPDATE! Regarding that chatty grill: I should have posted this before.

I was resigned to live with it, but John called to check again that everything was working fine and I threw th

So, in a few short minutes John managed to save me several hundred dollars (at minimum) by diagnosing a problem the previous technician (not HVACnerd) had created. I was previously told I was going to have to replace some parts, but instead John figured out that they had just switched two wires so the fix is fast and easy! I so appreciated the time he took to explain - and draw - my whole set up, and he also showed me how to help my system work a little better using my existing Nest units. He was super nice and knowledgeable -- I would 100% recommend and trust him to fix your HVAC!
