John is the CSI meets MacGyver of the HVAC maintenance, repair, and installation world. There is no problem too complex to confound his expertise or exhaust his commitment to finding the right solution. This guy does not give up! Nor does he opt for the easiest or most profitable solution for his own bottom line--pushing you to replace parts, major components or entire systems unnecessarily. He's customer-centric to this core. He diagnosed my problem over the phone and, upon arrival, went straight to fixing every part by hand, all to save me from buying expensive new parts and being without my air conditioning in the meantime. John is the sort of service provider you don't encounter very often these days. He's also the kind whose incredible value won't be fully clear until you've seen his dedication and abilities first hand and realize how much he's saved you on the back end. I cannot recommend John more highly!

John promptly responded, quickly diagnosed the problem with my furnace (broken relay), and replaced the part and everything worked subsequently.

John was able to diagnose the heating issue after I sent some pics and video. When he showed up it was a pretty quick fix. Explained everything in general terms so you fully understand what he did. Would use again and recommend to others.
