A/C techs and installers very professional. Knew what size A/C unit we need to replace old A/C unit. John Jr co owner very friendly and made sure we knew what needs to be done for install . John Jr schedule install time and date . DeModica crew was here early did install and afterwards cleaned up mess from install. Also, A/C tech Curtis explained new Thermostat and set temperature. We will always use DeModica A/C and Plumbing for our home needs . Thank you Albert and Elva Nunez

Our Technician from DeModica AC was very knowledgeable and informative. He was considerate of our concerns and needs for our household needs. He was very professional, respectful, and courteous during his visit. Looking forward to seeing their proposal and moving forward.

John was very responsive to our request for service. He fit us into his schedule, diagnosed the issue, and fixed the problem very quickly.

Demodica AC is great. Honest, professional and quick to respond and repair. John just installed a new AC unit and took care to do it the right way and at a good price. Highly recommend.

This company was highly recommended to me by a good friend. I discovered I had a leak under my kitchen sink that necessitated the replacement of an old garbage disposal. I called at 10 AM on Thursday and asked for help before the weekend. They had a plumber at my house by 2 PM that day. A younger gentleman from New York (I can’t recall his name) who couldn’t have been more pleasant or professional.
I highly recommend this company.
Thank you to their receptionist and technician. Excellent.

Competitive pricing, on time, professional installation. John did the little extra things like taping before he brushed on waterproofing which left a clean straight line...personal professional touch. He also cleaned up after himself.

A1, Good people to work with. Very professional custom service and knowledge of A/C systems.

Quick service, extremely professional techs, immediate resolution and explanation of the repair. I couldn’t have asked for a better experience

I was purchasing a house, one of the AC inspected because of its age, they checked everything possible for me. Excellent job.

John DeModica was professional and transparent throughout the entire process. He made sure I understood the issue. He took his time to diagnose the problem accurately and provided a thorough solution. I am impressed by their professionalism.

John installed two (2) brand new, 2.5 ton mini split units in my RV Garage in Scottsdale and did a great job! Fast, efficient, knowledgeable, and clean service! Happy repeat customer and I will def use him again for my guest house which will be built soon.

Fantastic company. Quick to come out for service, quick to fix issue! John is a great guy who knows what he is doing and I felt super confident with his work. Highly recommend.

They were within 10 minutes of the opening window for their appointment.
John explained in detail the results of his diagnosis, and provided an estimate for repairs that didn’t change.
Honesty and integrity is all encompassing when it comes to DeModica Heating and Air conditioning.
Thanks guys ‘cause now I’m ready for that 116 degrees!

While it’s not ideal to have a failure on a system, that’s six weeks old the response time and professionalism was top-notch

Great customer service and onsite repairmen.

John Jr of DeModica Conditioning helped us with a defect in a thermostat. John Jr was concern and returned call right away, NOT DAYS later like other companies. Within a day during a busy AC time was repaired . Thank you very much John Jr for your customer service. DeModica Plumbing and AC will always be are call on our homes. Randy Nunez

I am very pleased with DeMonica. I highly recommend them!!

We couldn’t have asked for better service!! Jonathan was really great at communicating with us, showed up when he said he would and did a phenomenal job with the instal. We love the unit as we can barely hear it when hanging out outside and inside temp is perfect. Thanks Demodicas!!! We love it!!

Awesome job as usual! Always can count on DeModica to execute!

I’ve had a consistently excellent experience with DeModica Air Conditioning. They are always quick to respond and show up promptly for service, which is a huge relief when dealing with AC issues, especially in the heat. Their team is professional, courteous, and clearly knowledgeable. What really sets them apart is the informative follow-up they provide after each visit — I always feel well-informed about the work done and any recommendations for future care. Highly reliable and trustworthy. I wouldn’t hesitate to recommend them to anyone in need of HVAC service.

John came with his assistant Curtis to replace a starter kit on my Trane AC. First time I had used him. Both guys were very pleasant, on time and fairly priced. John explained what he was doing and answered all my questions. Many thanks for a job well done!
