Very impressed by his knowledge
The company John Stevenson just sent me Fernando to check on my furnace and A/C units. Fernando is very knowledgeable and has a degree in his line of work. I was very impressed by his knowledge and professionalism. He explained in detail the current condition of my furnace and A/C equipment and also looking ahead to future possible upgrades to take advantage of my solar system to reduce utilities cost. I am very pleased with the service I received from Stevenson CO and specifically from Fernando Jarquin.

Honest, quick, fair, and professional
Honest, quick, fair, and above all else, professional. John Stevenson was a solidly positive experience from start to finish. Our HVAC system was eight years out of date, and they walked us through our options, worked with us to find the best solution, and then, every bump along the way, they communicated and made sure I was aware of the situation. When it turned out that our space was too small to move forward, the two technicians installing our unit, Hunter and Isaac, truly went above and beyond to ensure that our home had heat. I would give more than 5 stars if I could.

Pedro earned a 5-star rating
For my HVAC system care, I hired John Stevenson Company Plumbing & Heating. I had the most impressive, knowledgeable technician, Pedro. He explained in detail how the system works, maintenance and care, and improvements. I’ve owned many homes but have never encountered someone as good as Pedro. He earned a 5-star rating!
