"Overall, it was excellent. Jerry (the owner) came out and was very straight forward as to what needs to be done. Price (compared to 6 other companies) could not be beat. Work was scheduled reasonably quickly and went smoothly. Problems were discovered after installation and when made aware, Jerry and his crew made sincere efforts to set it right – and were able to solve the issues in couple of visits. All of the crew and management went out of their way to ensure that we were satisfied with the work and overall result. Would definitely consider Liberty Plumbing for future work."

"I am thoroughly impressed with the exceptional service I received from HD Mechanical! Their team recently installed mini splits in my home, and the entire experience was seamless and professional. From the initial consultation to the final installation, their expertise and attention to detail were evident. The installers were courteous, informative, efficient, and ensured a precise installation. The mini splits are now providing comfortable and quiet heating and cooling, exceeding my expectations. I highly recommend them for their accuracy, professionalism, and top-notch service. Five stars and a job well done!"

"Installation was smoooth, it was done within a day. There was high pressure sales involed which I succumbed into as the sales guys were saying that I had fiber damage in my ducting and since I have kids in the house they said that it was very crucial that I do the change now. It was my fault to not do any more pricing research hence I was a bit gouged."

"He did a great job and really clean my vent."

"I’ve had so many AC technicians through my house, and I have to say, Carlos Cetz is the best technician I’ver ever had. I’ve had him four times now, and he has solved all my problems no matter how complex, weird, or alarming. Carlos is always so calm, observant, and very, very knowledgeable. The first problem was when I had a lot of water coming out the side of my house. Carlos knew what the problem was and went to my attic. There he saw the drain wasn’t draining. He was able to drain it and found that cement, insulation, and dirt was stopping up the drain. This must have been from the time my house was built. The second problem was a problem I had called many times for and no amount of technicians could figure it out. They would say it was the door rattling, the motor was dirty, or another excuse. But Carlos did a thorough inspection and found one motor needed replacing. When I told him the noise was only on the upstairs unit, he inspected it well and said everything was in working condition. Carlos went out of his way to inspect the room where the noise was coming from. He found it was from one of my light fixtures in my study room that was making the noise due to the vibration. Sure enough he was correct. He tried getting the loose screw out, but it was too deep. I need to call an electrician for this problem, but I am so relieved. This noise was bothering me for a year and a half. I kept hearing it day and night and kept thinking something was going to break in my attic, but now I don’t have to worry about that. Carlos finally solved this annoying mystery, and I am just so grateful! The third problem was a rancid smell coming from my air conditioner vent. Due to my asthma and on-going fires around me, I had the fan going on all day and night and the air conditioner going on and off throughout the day. Carlos was able to explain how the condensation around the air conditioners work and why this situation was happening. Immediately we knew that that’s what happened. Even when I had a hard time understanding the mechanics, Carlos illustrated it so well. Carlos is so smart and a great communicator. He has a presence about him. Whenever I see him, I know my house is in good hands. He always uses a shoe cover when coming into my house, pets my barking dog so she isn’t scared anymore, covers my clothes with sheets, cleans the insulation that fell from the attic, and explains clearing what he did to solve the issue. The fourth problem was with the motor that was used to blow more air to the room farthest away and over the garage. The room gets so hot during the summer and cold during the winter. The motor kept failing to blow. Then Carlos had a creative and brilliant idea to connect it directly to the A/C and heater directly. Sorry this is so long, but this survey is way overdue and covers 4 different services. To sum up, Carlos is the best technician I have ever met. Thank you On-time Air for having caring and knowledgeable technicians like Carlos."

"I would like to share my experience with this particular company.my husband and I both feel that we were treated professionally and with courtesy and gave us a wonderful product that was affordable. The servicemen that came out to install our air and heating unit where professional and answered all of our questions. We would recommend this company to anybody who needs AC and heating services they're fast quick and easy to work with. I really feel that this company also does not take advantage of seniors or try to talk them into things they don't need or into larger units they expressed to us a fair price for their product and labor. Anybody interested in this company please ask for Frank. This is the man that knows all the answers."

"I am very pleased with the quality of work Matthew, Shawn and their staff did with the Main Sewer check valve replacement and the Main Shutoff Valve replacement. The Main Shutoff valve replacement and the Hydro Jet cleaning of the Main Sewer line was not part of the initial job to be done. Matthew authorized the added job without additional charge to the original quote I was given. Matthew and Shawn has great knowledge and answered all my questions to my satisfaction. They gave me a fair price, they were very professional, thorough and polite, from beginning to end. Clear explanation of needed repairs, sound advice without any inkling of price gouging or questionable add-on expenses whatsoever. Respectable and conscientious, could not be happier. Even very neat and clean. The people that worked with Matthew and Shawn were also very professional and very thorough. I will recommend them to my friends who need a plumber and call them again when the time comes I need a plumber. I will rate the work they did with A+ and Excellent!!!"

"Perfect. All done in one day and the installation looks like it was done by a surgeon."

"Kayvan was a wonderful service tech! He was on time and professionally checked out the water heater and the HVAC system. He was so polite and friendly. He explained the need for a new filter in the heating unit and showed me photos of the unit located in the attic. He also offered to do a friendly deed for free, which I greatly appreciated, He’s a great asset to Service Champions!"

"Josh was the last tech is came in to do maintenance but every tech thatâ s come has been top notch. They are always polite and informative. Iâ ve been using this company for 6 years and couldnâ t be happier. I highly recommend this company!"
