Arizona’s Best Heating and Cooling is truly a professional business that I highly recommend. My a/c unit went out and they responded very quickly. My unit needed a major repair and AZs Best gave me many different options to include repairing my a/c unit or doing a complete replacement. Different pricing options were also offered and I decided to have them do a complete replacement of my heating and cooling unit. They changed everything out in one day and I was very impressed on the clean and professional work they do. I will definitely use them again in the future if needed. Arizona’s Best is truly the best!

I have had several visits by Az’s Best Heating and Cooling. Oscar, Jr. & Sr. are both very reliable, dependable, and knowledgeable. They do excellent work at a very reasonable price. I called once with a leak on the roof and they were here within 24 hours and fixed a rather serious problem with drainage of the system.

I am very pleased with their service. They replaced my old furnace and installed new central AC. They respond promptly to calls, show up on time, and do excellent work. Mr. Leyva even filled in and submitted the warranty paperwork to ensure I get the full benefit.

In November I had Arizona’s Best Heating and cooling install a heat pump and replace old sheet metal duct work in my home. I was very impressed with their customer service from our first meeting, right through to the completed project. They were very professional, and the work was completed when promised. When the inspector for the city of Tucson came to inspect the finished project, he stated the work Arizona’s Best had done was some of the best he has ever seen in years. I am very pleased to this day with the quality, price, install, and professionalism. I recommend them highly, and have recommended them to several people. If you want your project done right, on-time, with a fair price….don’t hesitate to call them!

High quality service at a very competitive price. I’ve never had an issue they cant handle. I recommend them to all my family and friends. Nothing I respect more than an honest business man, and a Tucson business owner.

I highly recommend Arizona’s Best Heating and Cooling! My a/c went out and they responded very quickly. My a/c unit needed a big repair however Arizona’s Best gave me many different options with different prices on either repairing or replacing my unit. I chose to replace my whole a/c system with the best option I could afford and Arizona’s Best did a very good job on the replacement and also had everything swapped out in one day to include my furnace in the attic. These guys are truly professionals and do very clean work with outstanding customer service. There pricing is very hard to beat and I will definitely call them again in the future if needed.

Oscar Jr and Sr are the best. They’re work is detailed and very professional. They replaced our extremely old and outdated cooler and heating system with a new ac/heater unit. They left us with helpful tips and the only time they had to come out was because we hadn’t replaced the filter and even when it was our fault they were very kind and understanding. They also replaced my parents cooler for a new ac on their mobile home out in 3 Points. It’s worked extremely well and when my dad was still here and he needed they’re help or had a question either Oscar never hesitated to answer the question or go out to 3 Points to help my dad. Now that my dad is gone my family and I continue to trust them 110%. Thank you for all the hard ..efficient..and awesome job you guys do.

Oscar is the upmost professional ! He never missed a call/text /email and every job detail was explained concisely , without deviation of what he committed to do ! Az Best is competitive ,prompt and courteous! Also treated my tenant with the upmost respect !
