We had an incredible experience with Alliance Heating and Cooling, especially with Eric Walker. After about 11 hours of trying everything we could to rescue our cat who had fallen down our vent system, we were exhausted and out of options. I called around to multiple companies, and no one could help—until I reached Alliance. They sent Eric, who was kind enough to come after hours to help us.

Eric was so pleasant, patient, and genuinely caring. He went above and beyond to help us get our cat out safely. It’s not every day you meet someone who shows that much compassion and dedication to helping others. There truly are good people in this world, and Eric is one of them. We’re beyond grateful!

I called on a Friday at 1pm and had two very knowledgeable technicians(Eric and Dillon) at my house by 4:30 ready to diagnose my issue. My system is barely a year old and my mistake is I purchased a new HVAC system from a company that was not them. They took their time and found my board on the outside unit was not functioning properly and found a way for it to run through the weekend to keep us cool. Monday afternoon they showed up and had the new board and thermostat installed very quickly. They answered all questions and even showed us the issues. We highly recommend this company!

With each service, they not only perform the job but go above and beyond in explaining the work being done and educating me on how to self maintain my units thereafter. I would highly recommend them for your go to HVAC service. You will NOT be disappointed.
