"Mayel and The Comfort Gaurdians did an excellent job installing two split system units and replacing our home main HVAC system. Very pleased with their work and how easy it was to work with them. I’m a HVAC engineer so i’m sure i’m hard to please as a client but The Comfort Gaurdians were excellent and at a fair price!! Give them a call!"

"Computer did the "gotta send info to Microsoft" but when tried to reboot it ran through automatic repair without success. I did all the alternative without any success. He came and picked up the hard drive on Tuesday and returned it on Saturday. Fortunately he was able to "restore" without any data loss. Very happy with outcome."

"My initial experience with the technician was poor but after calling and talking with their customer service rep the issue was resolved promptly. The owner came and finished the job personally and apologized for my inconvenience. Their level of communication and professionalism is worth going back. Such great customer service which is rare to find in this day and time."

"The radio commercials for Casteel are what steered my decision to scheduling my main waterline repair with them. However, after the experience that I had with their team I will be utilizing them for all of my future needs. The dispatch and scheduling office were pleasant and professional as well as never having to be on hold for (not exxaggerating) more than a minute. From then on they maintained communication with me via text and email so that I was never left in the dark. Jonathan was right on time, very thorough and knowledgeable, checking to make sure that everything was back in order before ever mentioning payment. This is the kind of service that you need from an already stressful situation and is my primary reason for recommending these guys. Turns out the house has a blue ploy line which was discontinued a while back for constant leaks. Bad luck for me that I missed the recall window but I know for **** sure what team I trust to replace my mainline. It's a long stretch of yard that they will have to trench to get the line put in with several ways that it could go wrong which affects my estimate but after enough experiences with other companies I know that you get what you pay for and your fresh running water is not something to attempt the cheap way. Even with that, they applied the cost of my mainline repair to the replacement which put my total damage at around 4500 clams. If you have to drop that kindof cheddar on your home maintenance youre gonna need the assurances that come with a company that goes above and beyond to earn your continued business and that is what I felt with Casteel. TLDR; they make at least one thing on your "to do" list simple and as pleasant as possible."

"I had another company come out. I was waiting on a part. I called Paul, he came out and we have heat so warm -- I had to turn it down while he was still working on it! Now that is service! I got options for repairs and replace. He even took dimensions in case we want to replace the air handler in the future! RECOMMEND VERY MUCH! Thank you, HomeAdvisor for sending us Paul. And thank you Paul for your patience, info and time with us today!"
