"My appointment was on Monday 1/5/2026 to fix a leaky shower faucet that had continuous running water. Jordan Benavides responded and came to the job ill-prepared and without the proper tools to complete the work. He went to Home Depot, came back and still didn't do anything. He had one excuse after another and spent more time at his truck than on the job. I have him on videotape going to his truck 15 times, even sitting idly one time for 15 minutes. He charged $530 for the job and tried to price-gouge me for more business. After 2 hours of him stalling, I called dispatch and sent him on his merry way. I was left with a leaky faucet and a damaged shower handle which was working before. I called another company to fix the handle and solve my problem. If Jordan is indicative of the caliber of technicians Casteel employs or subcontracts, I will not be doing any further business with Casteel. "

"Customer service was great "

"I am VERY disappointed in my experience, even though it started out positively. Justin, the sales rep, was very helpful and I paid my deposit right after Christmas. However the customer service since it was installed has been less than optimal. The system has now shut down 3 times. I paid almost $12K for it. Este's says that the manufacturer has to send someone out to upgrade the computer. No one can tell me when that will be. Unacceptable."

"We had a full HVAC system replacement for both floors of our home, and we are truly grateful for the service we received from Weather Masters. From the beginning, the owner was understanding of our situation and worked with us on the pricing in a way that no other company was willing to do. He adjusted the cost significantly — almost as if we were paying cash — which meant so much to our family during a stressful time. The installation was done professionally and efficiently, and the team was respectful and organized throughout the entire process. It’s rare to find a company that combines professionalism with genuine care for their customers. We truly appreciate Weather Masters and highly recommend them. Thank you again for helping our family."

"I contracted the services from Farm Fingers and paid upfront. They never showed up to the job, as they agreed. I decided to use another service."

"They found nothing wrong with it and just changed the filter. They responded quickly, was very respectful, and just wanted to make sure everything was okay. I can't rate them high enough and I would highly recommend them. I would definitely hire them again."

"I highly recommend this business. The technician, Pierer, and his colleague were true professionals and incredibly courteous. Even though I was their last appointment of the night, they went above and beyond to source a replacement part that wasn't stocked on their truck. I truly appreciate their dedication to getting our HVAC unit running late in the evening. Thanks to them, my family was able to sleep comfortably with the heat restored."
