Mammoth Services

Mammoth Services operates out of Gilbert, Texas, with a clear focus on HVAC work for both homes and larger property portfolios. They cover areas across Texas and into Arizona, handling maintenance needs for property managers who run multiple residential sites. The company takes on service calls that keep cooling systems running through long summers and handles the kind of routine upkeep that prevents bigger breakdowns later. Their approach centers on quick work orders, photo documentation of every job, and steady communication with the managers who hire them to keep tenant calls from piling up.

In Gilbert the heat pushes HVAC systems hard, so crews stay busy with compressor repairs, coil cleanings, and full unit replacements when older equipment fails during peak season. They move through properties fast because managers need jobs closed before the next complaint comes in, often arriving with the right parts after looking at prior photos from the same site. Technicians handle everything from filter swaps on rental houses to ductwork fixes in larger complexes, and they log each step so owners see exactly what was done without extra trips. This kind of steady, documented service fits the local market where summer calls can stack up quick if a system sits idle for even a couple days.

Customers keep coming back because the crews show up when promised, finish without cutting corners, and keep costs in line with what the work actually takes. Reviews point to reliable speed on urgent calls, solid quality that holds up after the first heat wave, and clear talk on what needs fixing versus what can wait. Price feedback stays positive when the bill matches the estimate given on site. DIRT Score 4.8 from 350 reviews on Finds.

“For any of my maintenance and restoration needs, I always go to mammoth for their great value and exceptional skills for handling such service requests. They are phenomenal and very professional on how they get their services done. Special mention to Eric for his flexibility, timely updates and meticulous panning/execution of the service request.”

“This is the first time I’ve had mammoth services out for general repair, but this is the first time for an AC tuneup. Kendrick was the technician. He was very knowledgeable, and out of the four technicians that have been here servicing the AC (another company’s techs). He’s the only one who asked about the second blower because we have two units. He is very knowledgeable, approachable, has great customer service and a good heart. He deserves a raise. Highly recommend Mammoth services.”

“I’ve had the opportunity to experience the highest level of service, organization, communication, and professionalism from Jimmy and the team at Mammoth over the past couple of years. They’ve consistently been reliable, helpful, and great to work with. I can’t recommend them highly enough — truly a 5-star experience all the way.”

“Kendrick did an amazing job! Very quick, and respectful. Answered all of my questions in a way I could understand all while saving us from the scorching heat! Thanks Kendrick!”

“Leanna and team at Mammoth do a fantastic job. Professional and stay in communication when an issue arises. Happy to partner with them. They ensure their clients and properties are taken care of.”

“I had the pleasure of dealing with Kendrick when my Ac went out. He was able to come in and have it fixed under an hour and made sure everything was functioning properly. Glad I didn’t have to sit around in 100+ degree weather all day.”

“Mammoth Services has been amazing. They always show up promptly, and provide professional services to our home. We generally get the same tech every single time, Michael. He has been so great every time he is here. He is friendly, professional, and knowledgeable. The most recent time he was out, our downstairs AC went out. When he showed up, he walked through what he was doing to fix the AC with my husband. He took his time to explain the repair and show my husband everything he was doing and why it happened. The level of knowledge he has is incredible. On top of that, the office staff and service coordinators are extremely friendly as well. I’ve spoke with Lydia and Leanna on multiple occasions and they always go out of their way to ensure the scheduling fits my needs as well. When the AC”

“Mammoth made false repair reports I was aware of when I hoped on a plane to go verify their claims personally, as I guess they didn't expect the owner to do. Mammoth was hired thru On Q management, I would strongly advise you stay clesr from. I was in shock to also see the additional damages Mammoth created that were not their when I was at the property 2 weeks prior such as black hand marks on brand new painted walls & trash left everywhere I know was Mammoth as no one was in the property prior but me. Landlords I siggestbyou stay clear of these folks.”

“Kendrick, with Mammoth Services, arrived at our home as scheduled for standard AC maintenence and check. He was friendly, presented himself professionally, was knowledgable and inforwative and someone I felt comfortable having in our home.”

“I was having problems with moisture accumulating in my laundry room with the dryer and Mammoth services came out to find out what was going on. I can’t say enough about Kourtney and Mike. They came in and found the problem and did a phenomenal job with getting it fixed. I really feel like they went beyond their Expectations and gave extraordinary Customer Service. They were very nice and very easy to work with, Thank You Courtney and Mike for finally finding the problem after two other companies came out prior and did not find what you found. I am very grateful and thankful for your work and now I can put this moisture issue behind me. 😊”
