One Hour air conditioning & heating replaced my 30 year old unit including all duct work, vents, thermostat, and rebuilt the stack head. All in one day. My initial contact person was Matt who was very professional, informed and definitaly knew his job. He politely answered all questions and took the time to explain everything completely. On install day, Nick, Jay and Thomas called to let me know they were enroute then after arriving went straight to work. All three were knowledgeable, experienced, and professional, plus had great work skills! After all was done they took time to answer any questions and show me the unit's features. I am very pleased with the unit, their install and its performance. A top shelf experience and I would definitely recommend them and their company to anyone needing a really cool product.
