Diaz Air Conditioning has installed and serviced systems in commercial buildings throughout the entire metro New Orleans area.
Unfortunately, some contractors merely size a new system based on the old system's capacity rather than completing a professional design. Very often, we see that the original system was not sized properly to begin with. Guesswork can lead to improper sizing of a system which can reduce the comfort of your home.
What would happen if you never changed the oil in your car? Or, what if you never checked your car's tires for wear? Like your car, your home or business's cooling and heating system requires regular maintenance and service to operate safely and efficiently. Without it, serious problems can develop, causing you a great deal of damage to repair.
As a leading provider in energy efficient home products Diaz Air Conditioning is proud to use only the most efficient and most reliable products on the market. Diaz Air Conditioning is committed to using industry leading products from distributors based in Louisiana. See a listing of our products and suppliers below!

They upgraded my old house with a fabulous ductless HVAC system. I'm cool in every room and no more ugly window units!

Diaz Air Conditioning Service LLC just finished installing our AC unit. They were very professional, clean, thorough technicians and answered all our questions about the new unit, thermostat and filter unit. Highly recommended.

The best A/C experience i've had in NOLA since i've begun working in the property. Professional, affordable, knowledgeable...almost a little too good to be true! After being exhausted from dealing with either prices that are beyond what they should be, or techs who don't want to perform the work, Miguel and his crew find a way to be both cost-effective AND ready to do the job. Top recommendation.

We called Diaz Air Conditioning when it was noted that our air conditioner was leaking water all over the place and there was a significant amount of sludge accumulated in the vents. We got an appointment almost immediately and Gus, came that SAME DAY!! He was personable, efficient and very thorough. He had to come back the next day to finish up his work and he made sure that everything was done properly and thoroughly. There were things he could have done to charge us more, but he recommended that wasn't necessary and was very honest about everything. Fair price too for everything that he did

Gus Moreno arrived and checked out the system after we had water from the coil pouring down our wall and the system was not cooling. I first began to feel suspicious when he decided he needed to undo all the wiring to the condenser unit. Suspicion rose when he didn't bring any electrical equipment or gauges to use during his diagnosis. It about 15 minutes for him to conclude that our entire system was toast and we absolutely needed to install a whole new one to the tune of nearly $4000. He kept going on about how this was the best deal. Feelingy skeptical, I managed to get my usual guy, who upon
