Dr Dio Heating and Air Conditioning - Hacienda Heights, California

Braulio Medina

We had a great experience with Dr.Dio. My air conditioning unit was having issues, and he was quick to respond, professional, and honest about the work that needed to be done. He explained why the unit wasn’t working and didn't try to upsell unnecessary services like other companies. The job was done efficiently, and my AC is now working perfectly.

Dr Dio came out and fixed our ac.
Not only did he fix it but he also provided excellent customer service! Very honest man. I didn’t feel cheated or scammed with my money! I will definitely be referring Dr. Dio to my family and friends.

Dr. Dio came to my house before his first appointment and fix the problem. He lent me a capacitor in the meantime. He came back the same day and replaced it with a new one. He saved me a few hundred dollars. I highly recommend him. Lisa C

My AC decided to break down during a heatwave and I was desperate to have someone come out right away. I immediately reached out to my dad because I wanted to use his guy (Dio). Despite being super busy, Dio was quick to respond to me and even offered to come out himself the next day even though I'm *WAY* out of his service area! Talk about service!

Dio diagnosed the problem when I first texted him and his in-person visit confirmed his suspicions. I was extra confident with his assessment because I reached out to my friend's husband who also owns his own AC company and he suspected the same problem.

Dio also made a great recommendation for a safety valve so the AC would automatically shut off if leaking were to occur in the future. He always looks out for his customers!

If you're looking for an AC guy, don't hesitate to contact Dio. I could have easily called any random person to service my AC but why would I want to risk going with a stranger? It's hard to find reliable and trustworthy vendors these days so take it from me and call Dio!

Dr. Dio comes through again! I don't know why I had never reviewed this business before. Dr. Dio had previously done an installation of a new HVAC unit at my mother's house in early Dec. of 2017. That job entailed new duct work since her house had been built in 1971 with only central heating. Dr. Dio had done an awesome job with that so we call him for regular maintenance on that unit (annual check-ups). Last year, our regular HVAC guy at our house retired so now Dr. Dio is our HVAC guy at our house, too. (My husband had used his own guy for something like 20 yrs. so he didn't want to try my guy out of loyalty to his, you know?) Fast forward to present: our A/C died suddenly this weekend so Dr. Dio came out today and saved the day. He came out, diagnosed the issue, had the part available thankfully, and took care of our A/C problem. Didn't charge us an outrageous price, either. He's honest and upfront about everything he finds when he comes out to diagnose your issue and gives you good advice to keep your unit running at its optimum and I truly appreciate that. I had originally found Dr. Dio on Yelp when our A/C broke down in the middle of a hot summer about 6 years ago on the weekend and no one could come out right away due to the heat wave. I had called a few people and Dr. Dio had actually told me over the phone how to fix the issue if we were handy. We're not handy, though. 🙂 I made a note to use Dr. Dio when I needed an HVAC guy in the future and that's how we ended up using him for my mother's installation of a new HVAC unit after comparing him to other quotes. He was honest and gave us good vibes and his quote came out on top. I have no reservations about recommending Dr. Dio to anyone.

If you’re looking for an AC guy, give Dio a call. He will do what is in your best interests rather than doing what makes him the most money. Trustworthy and does fantastic work. He even left my place cleaner than he found it.
