Condo living. No heat. Just cold air. Tried to figure out how to fix - change batteries on thermostat, etc... no luck. Same day appointment. Thanks to Richard and Infinity Heating & Cooling, ready for the Las Vegas winter. Definitely a job for a Professional. Honest and unparalleled service. Prompt, efficient, and informative. Learned a few things from Richard. Remember back when "he does it for a living" meant that the guy was really good at it? And that he took pride in his work and professional reputation? Infinity is that type of company because at the end of the day...they are working in your home. After all was said and done, he recommended waiting to make sure all was working properly due to the Aqua Thermal heating unit. Patience is a virtue when your dealing with water. I would definitely recommend Infinity to a friend, family member, neighbor or colleague. Thank you Infinity and thank you Richard.
