Frontier Cooling & Heating

Frontier Cooling & Heating runs as a second-generation family-owned HVAC outfit out of Mission, Texas, and handles work across the Rio Grande Valley. They focus on residential air conditioning and heating with repairs, new system installs, regular maintenance, air duct work, blown-in insulation, and indoor air quality fixes. The company lists services like mini split setups, pool heat pump installs, and smart thermostat work, and they have been active in the area since 2006. They also carry an A+ BBB rating and offer financing options for bigger jobs.

Homeowners call them for AC units that stop cooling in the heat, full system replacements that run all day without issues, and routine maintenance visits that catch problems like rusted heater packs or missing disconnects. Techs such as Kason, Eddie, Trey, Jose, Tre, Joel, Nate, and Andres show up to diagnose issues, clean coils, explain what needs fixing in plain terms, and finish repairs or installs the same day or next day. Reviews note jobs where crews like Manny and his team worked long hours to complete an install in one go, or where David stayed in touch about schedule changes so the family knew what to expect.

They cover towns from McAllen and Edinburg to Brownsville, Harlingen, Weslaco, and other spots in the valley, with many customers getting same-day or next-day appointments after a quick call. Techs arrive on time, keep the homeowner updated, and handle everything from attic work to outside unit checks without rushing. Pricing comes across as fair based on the work done, and crews clean up after themselves during installs or repairs. The business keeps regular hours and responds fast even on weekends or during heat waves.

Reviews give the company a 4.9 Google rating built on repeated mentions of clear explanations, thorough checks, and reliable follow-through from the listed technicians. Customers keep noting how the team handles maintenance plans, emergency fixes, and new equipment installs with steady attention to detail.

“I had an excellent experience with Frontier Cooling thanks to Kason. He was very polite, respectful, and had such a cheerful, positive attitude. He took the time to explain everything clearly, gave me honest recommendations, and made sure all of my questions were answered. His professionalism and outstanding customer service really stood out. It's hard to find employees who genuinely care about helping customers, and Kason definitely does. Thank you for making the experience so easy and pleasant!”

“Eddie and Kason from Frontier Cooling & Heating Eddie and Kason pulled up in Frontier’s yellow Air Condition & Refrigeration van with “We’ll Help Keep You Cool” on the side — and they actually did. They came out for the Cowboy Kool Club maintenance and did a full, careful service — not a rushed visit. Patient, professional, and they walked us through everything in plain English: what they inspected, what they cleaned, and why it matters when a system runs this hard in the Valley. No rush. No upsell. Just clear answers, respect for the house, and an AC that felt better when they left. Frontier’s commitment to the Cowboy Kool Club shows in the way Eddie and Kason work.”

“Very pleased with the exceptional service from Frontier! My husband called to request service, and we were able to get an appointment the very next day. Our service technician, Kason, provided outstanding customer service. He demonstrated his knowledge and professionalism while taking the time to explain the maintenance performed. We appreciate his excellent work and highly recommend Frontier for their prompt, professional, and reliable service!”

“I was happily surprised by the professionalism shown David and his team. David was all the time in contact to let me know of any changes. On the actual instalation, Manny and his crew worked for over 12 hours to finish the job in one day and left my family very happy with the results. Now we just need to wait and see the coming savings on electricity and maintenance that the new a units will bring. I should also mention Nancy who was always very patient and provided us with all the information regarding quotes, discounts and financing. Thanks”

“Happy new year latest update as I update here. I delete from below. Justin came to my house December 31 to do my biyearly Service, they did a great job checked everything out and found that my heater pack was rusted. I didn’t have a quick disconnect or search protector on my main unit upstairs. They gave me a price quote to have one installed. So now I’m having to work and save some money so I could get the job done thank you, Justin. For a fantastic job. And your professionalism Latest update November 12, 2025 My blower motor came in. My coil came in. They replace both and my air conditioner is back up and running. The crew was here for five hours. Getting everything done. Checking and Richard. Checking That Everything. And I’m glad I found this Company carrier certified. I don’t know why the carrier. Company didn’t refer me back to them when I reached out six months ago and when I reached out a year ago. The Elko air-conditioning. Company did a terrible job. They didn’t listen to me. It’s a homeowner and they did whatever they want and not what was supposed to be done. And once again, the owner of Elco is a very nice and respectful gentlemen. But Junior, who’s running the Busine”

“Matt and Shea did an outstanding job installing my 5 ton Daikin, variable speed HVAC sytem, great technicians. Would recommend to anybody their work and knowledge on the installation. Got to my home on time, dismantled the old HVAC, cleaned as they go, installed everything as they mentioned on the contract, I was there the whole time of the demo and installation and would ask questions to them, very patient even though it was 100 degrees. They left late made sure everything was right before leaving my home.”

“I scheduled an appointment for AC service and was impressed by how quickly it was booked by Susana P on a Sunday unfortunately technicians werent available at time of booking but my service call was completed first thing Monday morning. The service took about 30-40 min and everything was handled efficiently from start to finish. The technicians Nate and Kason provided outstanding customer service, were very knowledgeable, and took the time to explain everything clearly. Their professionalism, expertise, and attention to detail made the entire experience smooth and stress-free. I highly recommend their services.”

“Kason and Eduardo provided exceptional customer service! In the middle of this heat wave, they both arrived with smiles on their faces and maintained such a friendly, positive attitude the entire time. They worked back and forth between my attic and the outside unit, never once losing their professionalism or kindness. Unfortunately, the phone technicians had to leave at 5:00, so they weren’t able to determine exactly why my unit keeps shutting off. Even so, Kason and Eduardo stayed to make sure the AC was still running before they left and reassured me that they would return to continue working on the issue. The charisma, compassion, and professionalism these two gentlemen especially Kason, showed were far beyond your everyday service experience. Although the issue wasn’t completely resolved, they left me feeling reassured and at ease knowing they were committed to getting it taken care of. Excellent representatives of the company and truly outstanding customer service!”

“Davian and JC installed our new heating and cooling system and did a great job! They both were very polite and professional. They worked a long day and stuck with it until they finished and tested it before they left.”

“Kason, excellent work yesterday. Your attention to detail and steady follow‑through really stand out. The way you handled each step made it much easier to pinpoint the issue, and I appreciate the level of quality you deliver to your customers.”

“We are having problems with our AC and they responded pretty fast. Tre was very nice, very knowledgeable, and very thorough in explaining the possible reasons why our AC is not working. He was also very patient with us and answered all our questions. He gave us convenient options in repairing/replacing our unit.”

“Great customer service! Been with Frontier for 5 years and they have really taken care of all my AC and air duct needs. They even came out to fix an air leak on short notice right after my warranty had expired at no extra cost! The technicians are courteous and professional, get things done in a timely manner. Highly recommend this company.”

“Andres from Frontier Cooling and Heating was very friendly and professional to work with. We bought a new unit from him and it was installed properly by Robert and Michael the next day. All of Frontier staff have been a blessing to work with. They are knowledgeable and professional. I would recommend talking to Andres at Frontier. They will do you right! Thank you all! 🙏❤️”
