Kialy was very professional and courteous. He did a great job. I felt I was in great hands from the outset.
Anthony Kent at Basnett provided top-notch service when I was seeking HVAC repair and replacement estimates. He was timely, professional, friendly, and walked me through various solutions that were budget-friendly and made sense based on my financial and home needs. Anthony even had this unique software that no other contractor brought with them -- it created a 3D diagram of my home so Anthony could measure all the doors, windows, fireplaces and other ventilation sources. This ensured he was assessing for my home's actual usage needs for heat and AC, not just guessing based on a rough estimate by eyesight. I was impressed with Anthony's professional services and found Basnett easy to work with and responsive to any questions or needs that arose. Highly recommend!
Matt did a fantastic job identifying and then replacing worn out parts in our furnace to keep it running efficiently. As always, Basnett Plumbing service is awesome.
Fantastic work from the quote through the install. Anthony was incredibly knowledgeable about what options we had for putting a mini split in our dining room. Cameron was very helpful during the install and answered all of my questions. Would absolutely recommend!
Gabriel with Basnett did an outstanding job. He spent nearly the entire day taking apart and cleaning each individual part for my 8 indoor/outdoor mini splits. Very professional and helpful understanding my options with great patience. Highly recommend Basnett and Garbriel!
Had a great experience overall. Kialy did an excellent job troubleshooting and solving a difficult plumbing problem, demonstrating an exceptionally professional attitude.
