HVAC reviews in Corona, California

Quantum air conditioning is very professional, prompt and courteous. I used them to instal 2 AC units in two different properties. I highly recommend them.

I had an old system that needed to be replaced and I checked several companies for price and service and honestly Quantum Air Conditioning the best. They came to do the estimate and 2 days later my system was up and running. 👍👍👍

My AC broke down late last night and this morning I called them and Jose was able to come out within minutes since he was in the area!!! The job was done super fast with reasonable pricing!!!!

QAC was very professional and very detailed in their accessment of the units. The customer service itself was pleasant and the technician was compliant and understanding of our Covid-19 protocols.

I highly recommend using Quantum Air Conditioning Inc for all of your A/C and heating needs. The employees are very considerate, professional, honest/trustworthy and pricing is exceptional

My family owns a rental property in Lake Elsinore that had an evaporative AC system (swamp cooler) only. Nine years ago Quantum AC and Jose Arteaga converted the house to a conventional HVAC system. The work was done quickly and professionally. The new system has worked flawlessly ever since. (sincerely, Robert E. Leach)

Quantum first worked on my rental property. He did such a great job I had them work on my home for maintenance work. Again great job. On time and great work. Thanks

I am ashamed to say that someone who I thought I trusted, Jose, scammed me and my family. We spent a total of $1,055 to have our AC fixed, but when it didn't seem to operate correctly, Jose refused to come out and help. DO NOT TRUST

I thought my AC at the end of it life. José came out, refilled the freon and let the coils defrost. It's been working like a charm ever since! Highly recommended.

Jose and Quantum Air Conditioning did a great job installing my portable air conditioner. Work was completed in a thorough and professional manner!!

I highly recommend this company for any ac/Havac needs! Jose is extremely friendly, professional and is a genuine and honest repairman. We will definitely be using him again for any ac needs!

Jose was on time and was very professional with his work. Everything was done in a very timely manner and I have no complaints and would definitely use him and this company again

Jose was polite and courteous. He worked with my scheduling issues. His price was fair. I would use his services again in the future.

I have hired Quantum Air a multiple times. Jose and his team are Outstanding! The price is the best I could find and they did a awesome job.

They cut corners on my mom's installation. 1 year later and she is still dealing with issues and with now the city breathing down her neck because her home is a fire risk. She finally paid out of her own pocket to have an electrician come check it out and they purposely connected her ac unit incorrectly to cut down on time and costs for them. Very unprofessional. We do have email proof and will be contacting state licensing board.

I called Quantum to repair our AC on a Saturday. I called at 11:30, they were there by 2:30, repaired within half an hour and for a fair price. I would certainly use them again.

Thank you Jose for your excellent service! We have been pricing differant businesses and found Quantruim to be the best and did not disappoint. Jose and his team are very professional, clean and quick. We highly recommend Quantruim Air Conditioning.
The Quintana's

Thank you

I highly recommend Jose and his team for your HVAC needs! They are fast, efficient and professional. And their work was a great price without sacrificing quality! I have absolutely no complaints

Jose has always been great with taking care of problems with A/C he is affordable and does excellent work. Anytime I have any issues with A/C I know too contact quantum A/C for quality work and overall good customer service

I highly recommend Quantum Air. Our HVAC system acted up during the cold weather last week and Jose came over within a couple hours of receiving our call. He was very professional and friendly. And, he fixed the problem for a very reasonable fee. We'll definitely be using Quantum Air for all of our future HVAC needs.
