What we do
Full-service heating & air for the Valley
From a quick repair to a full system swap, we handle it with real diagnostics and equipment built to last in Texas heat.
Central AC Installation
Instalación de aire central
Full residential and commercial system installs with Goodman equipment, backed by a 10-year manufacturer parts warranty. Sized right for your home, installed clean.
Mini-Split Install & Repair
Mini-splits y ductos
Ductless and ducted mini-split systems for additions, garages, and rooms that never cool right. Expert installation and fast repair on any brand.
AC Repair & Diagnostics
Diagnóstico real
We find the real problem before we quote it, no guesswork and no upselling. Honest diagnostics and repairs that get your system running again.
Duct Work
Ductos
New duct installation, repair, and resealing. Leaky or undersized ducts waste cooling and run up your bill, we fix the airflow at the source.
Refrigerant & Freon Service
Servicio de Freon
Low on refrigerant? We diagnose the leak, repair it, and recharge your system at a fair price, not just a quick top-off that fails again next month.
Humidity Control
Control de humedad
Valley humidity makes a working AC feel like it is barely keeping up. We balance airflow and moisture so your home actually feels cool and dry.
Why neighbors call Mundo
The owner is on the job, not just the invoice.
We built our name on doing right by people, documenting everything in writing, and charging fair prices the whole Valley can stand behind.
Quote by text, no trip charge
Snap a photo of your unit and text it over. We can price a lot of jobs remotely so you are not paying just for someone to show up.
Same-day & Sunday emergencies
When the AC dies in the Valley heat, waiting is not an option. We source parts and install same-day where we can, and we answer Sunday calls.
Goodman authorized dealer
Goodman equipment installed by an authorized dealer, with a 10-year manufacturer parts warranty standing behind the system.
Financing available
A new system is a big call. We offer flexible payment options so a comfortable home does not have to wait for the right month.
Everything documented by text
We keep communication in writing so you know exactly what needs doing, why, and what it costs. Nothing hidden, nothing forgotten.
Family-owned since 2015
Mr. Mundo and his son run the jobs themselves. You get the owner on your roof, not a rotating crew that never saw your house before.
Our story
A father, a son, and a promise to do it right.
Mundo HVAC started in 2015 as a true family business. Today Mr. Mundo and his son still run the jobs themselves, the same team you see on the roof at night getting your system back online.
We invest in our craft, from the AHR Expo to time at the Daikin headquarters, so the Valley gets modern, reliable equipment installed the right way. We carry Goodman as an authorized dealer and stand behind every install.

Real words from real Valley homeowners and business owners.
Not only did he tell us in detail what needs to be replaced, why, and if we don't, what will happen, the man kept communication through text so everything was documented for my records. Considering the times, he worked with us so good I didn't believe it till it was all done. Same day they had the part and installed it. Very very happy to do business with Mr. Mundo.
If I could give them more than 5 stars, I would. They repaired two old AC units at my business and had them running like new, and when I had an emergency at a rental property, they came out on a Sunday without hesitation. Their prices are fair, their work is thorough, and they truly care about doing the job right.
Had a great experience with Mundo HVAC for my AC repair. A huge shout-out to Marcos Jr., he was extremely knowledgeable and got my system back up and running perfectly. It's a relief to find a technician you can trust. Highly recommend their service!
The technician came fast and promptly fixed my A/C, very courteous and professional. They have the best prices in the RGV. I highly recommend Mundo HVAC.
Excellent service. The tech was very polite and friendly. He got to the root of my problem and resolved my issues. I highly recommend this company if you have any issues with your central air system or mini-split.
AC down? Text us a photo and we will price it.
No trip charge to get a quote on most jobs. Same-day service across McAllen and the Rio Grande Valley, including Sunday emergencies.
