Dr Dio Heating & Air Conditioning

After a lot of research, I decided on Dr. Dio to install a new furnace, new central AC (house never had it) new ducting, registers and attic insulation. Dio was very informative and professional through out the process. The installation was very clean and the house was left spotless. Dio is very knowledgeable and passionate about HVAC. I went with his recommendations and am happy I did. My AC is quiet and works fantastic.

Dr Dio was quick to respond and came out the next day to check out my AC unit. Honest and reliable. I learned a few things about maintenance. Cost was great. I inquired multiple HVAC companies in the San Gabriel valley area and he’s got the best pricing. Thanks for the fix!

For any issues you may have regarding your air conditioner or heater do yourself a favor and call Dr. Dio … Good to know that he’s around for any service, fair, honest, and dependable.

I own a barbershop and I’ve been seriously shopping around for an ac guy for a while and the end result is Dr gio! Straight forward no nonsense very professional very happy with his work.

I wanted to say thanks to Dr.Dio. He came answered my call after hours and gave me the help I needed to restore my AC during this LA heat. I would recommend his services to anyone who doesn’t want to be took for alot of money and still have a problem. He is very fair priced and I will use him later for my new AC install. Thanks Dio.

Thank you Dio. Older AC unit not blowing cold like it should and i called him based the Unilocal reviews and so glad I did. He was on time, professional, honest and courteous. He told me we just needed to change the filter and nothing more and showed me exactly what the issue was. He didn’t even charge for the visit which is the rarest thing now a days. I’m sold and will recommend his service to anyone who needs an honest guy they can trust, I will gladly reply to anyone if you message me about my experience. Thanks again Dio!

Dr. Dio save my life. I called Sears for AC problem and they told me I need a new AC system. I told him the AC is only 4 yrs old. Second AC guy told me I need to replace all the tubes and do all the test and it will cost me $ 300-​$ 600. 3^rd person I called Dr. Dio. I left msg. He texted me and I send him pictures and video. We do not have AC over the wkend and the weather is 105 – 110. Dr Dio came his the owner, he is so nice, clean, and professional. He is the only guy that brought booties entering my hm. He is honest. He assure me he will help me and will fix it. The temp inside the house is 86. In few mins he found the problem and my AC works. He make sure it works and he explain to me what he does ! He is a GENIUS! It saves me $$$. His price is so reasonable. Thank God I have 3^rd opinion. I was so tight on money. And he is a blessing to me. The best thing he told me on my very stressful day… I’ll do everything possible to reach out to you! I will do my best ! He is really the Best ! God is good. I will tell all my friends about him ! Thank you so much !

This review is for the installation of my HVAC from last year. Dio was very professional and courteous. He answered all my questions and was very quick to respond. I would very much recommend him to others.

My HVAC in the closet was leaking and made a huge mess with dripping water. Also I saw liquid in front of the a/​c unit which is outside the house. I didn’t know if the freon is leaking or if it was the water coming out of the HVAC system.
I called Dr. Dio and he was able to make an appointment for the next day. He came earlier than what he estimated. And I was not at the house yet and he offered to come back later. When I told him to go ahead using the lockbox that had a key. He went ahead and checked out everything. He checked the vent to see if cool air was coming out at the right temperature, if the thermostat was working properly, and check the a/​c unit outside with some gadget to see if there was enough freon.
When I showed up, he told me that everything is working properly. The reason why I had a water leak was because the a/​c left on for days and never turned off so it froze the tube and that was why water was leaking.
I offered to pay him for coming all the way and he said no. It was checked very well by Dr. Dio and I highly recommend him and his assistant.
They were polite, clean and very professional.

Dr. Dio is the best in the business! Literally an answer to prayer. He puts customers first. He showed up today after hours and helped us problem solve our malfunctioning electrical situation that was messing up our hvac system and got us up an running in no time. I thought it was an hvac problem, but he figured out what was causing it to happen and helped us eliminate that issue. This guy goes above and beyond. Hiring him is the best decision you’ll make today. Wish I could give ten stars. So thankful and impressed!

I finally decided to pull the trigger and make this large purchase/​investment towards my home and shopping for HVAC services isn’t easy, mainly the trust and quality of craftsmanship issue, but with Dr. Dio put all that aside. From the day of the estimate, to the agreement, to the installation date, to the clean-​up, everything was thorough, professional, clean and I mean this guy is like respectful of your home, leaves it the way it look before he got there. Possibly even better! I had spoken to him to install central AC and heating in my 1400 sq ft home and gave me 3 different options depending on my budget, I went with option 3 which was the best option long term. He came on time and started prepping the house from getting dirty and laying down drop cloths. They managed to get the job done in as little as 2 days which is very impressive but not only that, he upgraded the original 4 ton we agreed on to a 5 ton for me by Rheem and he promised me I wouldn’t be disappointed and he was right! I am also a blue collar type of worker and saving money is hard, spending it into something that cost so an extreme amount is even harder so I was peeking at everything he was doing and he had no problems showing me, explaining to me the functions and the way the ducting were routed. I mean this guy made me feel confident in his work. The job is now done and the quality, the craftsmanship and the better quality brands he chose to suit my home the best, made this install so seamless. They cleaned my house and vacuumed the floors to make sure everything was how it was before he showed up. I’ve put this install off for so long due to trust issues with contractors but man was I happy to have this guy service my home. Thanks again Dr. Dio! It’s about to be winter in the summer! If you do decide to go with Dr. Dio, you won’t be disappointed, just remember, they work hard and typically in hot spaces or outdoors so be kind and offer cooled beverages!

Words cannot express how grateful I am to Dr Dio. He came quickly to give an estimate for a completely new HVAC system which was very competitive and in a few days came back and did the work all in one day without any mess or disruption and even threw in several other jobs at no charge.
You cannot beat that.
I can highly recommend this Dr to you and tell you that you need look no further for any A/​C work. I only wish all Doctors were this competent.

Dr. Dio just finished putting in a new AC System. During a complete house remodel, he was reliable, meticulous, consistent, friendly, and above all, caring. He truly cared about doing a good job and making us feel 100% satisfied. He made sure that all of our needs and wants were met. Would highly recommend him to all of our friends and family. In fact, he’s doing my sisters house now. I have worked with many contractors and Dr. Dio and his assistant Jaime is at the top of the list!

I echo all the 5 star reviews for Dio. Truly a professional who did an excellent job from start to finish. I couldn’t be more happier with my new rheem a/​c & heater. Keep up the good work bud!

New install, new duct* On time, very professional, clean craftsmanship, promised everything from his quote. thanks dude

We will be only using him in the future! Never experienced such great service as this! Best guy to call for ac repair. Very honest and thorough. Didn’t charge to fix my ac and new filter even though I insisted. He is truly an angel!!! Made our day! :)

When you hire someone to work on your house, you want to know that they will provide top notch service. Dio does that and more. Not only did he complete the work but he did so by walking me through the entire process. He took his time to explain what he was doing and why he was doing it.
His extensive experience really shows and he is definitely someone you can trust to work on your home or business.
He did a great job putting in a vent for my dryer and running a gas line. He didn’t take shortcuts even though it might have saved him time because he wanted to do the job right.
I hired him again to do insulation in the attic. He did the job fast yet took time to insulate around the furnace carefully and add in framing around the attic access. Once again delivering above and beyond what was asked or expected.
Great service and will definitely hire again.

Dio came through for me today! Our A/​C conked out on us so Sunday I called Dio. He answered the phone even though his business was closed for the day and he told me that he’ll try squeezing me in Monday morning. Monday morning he lets me know that he’ll be there in a few hours and my A/​C was up before it got scorching hot in the afternoon and cooling colder than ever.
This is the second time I have called Dr Dio. Both times have been great experiences. Dio is courteous, clean, and his prices are reasonable. You don’t have to worry about an upsell with him and he tells it to you straight.
I will definitely be recommending Dio to all my friends.

From start to finish, Dr. Dio saved the day and did an excellent job on installing our Central Air & Heat unit. He was very patient and provided high quality service with many options at an unbeatable price.

I would like to echo all the great reviews that Dr. Dio Hearing & Air Conditioning has received on Unilocal.I shopped around with several companies before being able to make the easy decision to go with Dr. Dio. Here’s why:
1) Dio spent the time to not only explain everything he planned to do, but took the time to assess what the job would take. He also spent time to answer every question I had. The other people I got quotes from seemed in a huge hurry to leave after taking a look and never spent the time with me to know what I was getting.
2) Quality. Dio offered me a premium brand air conditioning system that has potential for expansion in the future, rather than low to mid-​quality brands that would require more repairs in the future. He also uses top of the line materials, not looking to take the cheap way out to make a few extra bucks. He secures the ducts in the attic to the rafters to keep them off the ceiling and prevent critters from being able to eat away at them. He also put some plywood in my attic to give a walkway to the furnace.
3) Speed. Most companies installing a brand new central air conditioning system take 4 – 5 days to complete the job. Dr. Dio spent only 2 days!!! His team spent the extra hours to get it done so it would minimize the time of schedule impacts
4) Professionalism. Dio sticks to the price he quotes, whether or not there are issues that cost him more. His cost was more than reasonable and he is one of the most professional and ethical people I’ve met in any business.
Dr. Dio also helped me out with some plumbing issues that popped up during his visit, and I cannot say enough how lucky my wife and I were in finding him to do this job. He has a passion for his work, and it shows tremendously. I am also very happy to say that he lives very close by, so I don’t have to go far for the best service!
I ended up with a 3.5 ton, 16 SEER central air conditioner for a great price, but even better service!
