Meet the Sensible Team

Phil Jensen

Phil began learning about the HVAC industry in 1976 and has extensive experience, including the service and installation of systems for both residential and commercial properties. He has designed large-scale systems for commercial buildings, custom homes, and new buildings in the Denver Metro Area and created systems for homes that need more comfort. Phil also owned and operated another small HVAC company for twenty-two years before selling and is excited to be part of the Sensible team and share his wealth of knowledge with Sensible customers. He’s also excited to continue the mission of providing alternative energy systems to homes throughout the Denver Metro Area.

Phil has been married for nearly 40 years and has two grown children and three grandchildren. He loves being a grandpa and can often be found playing catch with his grandson. He also enjoys writing, golfing, fishing, and gardening.

Jo Jensen

Jo began her career in the HVAC industry in 1991, when she went to work with her husband Phil as part-owner of their small HVAC company. Jo’s role quickly grew and evolved with her taking on responsibilities as office manager, bookkeeper, and dispatcher. After Phil & Jo sold their company, Jo joined the Sensible team in 2011 as the office manager and has been an integral part of the team ever since. Customers know and love her, and she continues to help expand the reach of alternative energy in Colorado.

Jo has been married for nearly 40 years and has two grown children and three grandchildren. Jo loves being a grandma and spends lots of time with her grandsons and granddaughter. She is also an avid reader, loves to cook, and enjoys interior design.

Neil Quinlivan

Neil began his career in the HVAC industry in 2007 and worked summers for a Golden-based HVAC company while working on his degree in geology. After working in the industry for several years, Neil left school to work as an HVAC technician full-time. He left the residential company he was working for in 2015 to work for a commercial HVAC and refrigeration company in Denver. Neil joined the Sensible Heating & Cooling team in 2018.

Neil keeps busy with his wife and two-year-old daughter and likes to homebrew and collect minerals in his free time. He’s also interested in renovating old homes in Colorado, as he is a fifth-generation Colorado native, and his family has deep roots in the state.

Tom Cassedy

Joining the Sensible Team in 2021, Tom enjoys working in a cutting-edge industry with a company, whose reputation proceeds itself when it comes to Geothermal work. He has worked in the HVAC industry for six years. Tom enjoys the challenge of keeping up with an industry that is ever changing. He says everyone at Sensible is encouraged to take ongoing classes and training. When the native Coloradoan is not working, he is taking advantage of the great outdoors fly fishing and spending time with his two boxers.

Frank Hernandez

Frank joined the HVAC industry after spending time in management. He likes the variety he finds as an installer and working with one of the few companies in Colorado that specializes in Geothermal work. Frank joined Sensible in 2021 and has continued his education within the industry, taking Carrier, Supply House and several manufacturer classes. Frank enjoys the great balance between work-life and time off that he spends mostly with his family.

Tiffany Freeman – Service Coordinator

Tiffany Freeman is the Service Coordinator at Sensible Heating & Cooling, bringing over seven years of experience in the trades, including scheduling, dispatching, administrative support, and customer service. Her passion for sustainability and helping others reduce their carbon footprint is what led her to join Sensible — a company that shares her values of environmental responsibility.

Working remotely from her peaceful home in Wyoming, Tiffany plays a vital role in keeping operations running smoothly while helping customers find energy-efficient solutions that align with their eco-conscious goals.

Outside of work, Tiffany and her husband Ian — a lifelong builder with 40+ years of experience — are in the process of designing and self-building their own off-grid, solar-powered home. Together, they are creating a sustainable lifestyle that includes gardening, raising chickens and goats, and providing a haven for rescued pit bulls. Tiffany enjoys spending her weekends exploring nature, bird watching, collecting rocks, crocheting, cooking, and reading. Her personal mission to live simply and sustainably is deeply aligned with her work at Sensible, where she supports others in doing the same.

Jake Jenkins – Technical HVAC Designer

With a bachelor’s degree in Environmental Studies and a deep passion for renewable solutions, Jake found a natural fit at Sensible — a company that blends traditional HVAC systems with innovative geothermal and energy-efficient technologies.

Before joining Sensible, Jake spent 9 years in the solar industry followed by another 9 years in HVAC, making him uniquely equipped to design systems that are both effective and environmentally responsible. He’s motivated by helping Denver-area homeowners stay comfortable while reducing their utility bills and energy consumption.
