I rarely leave negative reviews, but after spending nearly $3,700 with Guaranteed Service, I feel people deserve to know about my experience. I originally called on Wednesday because my AC wasn't cooling properly. I was told a technician could come Thursday between 8:00 AM and 12:00 PM. One night without AC wasn't ideal, but manageable—even with five kids, including two who are only 4 and 8 years old. The technician arrived Thursday, diagnosed the issue, and recommended a repair costing almost $4,000. After completing the work, he assured me the house would begin cooling within a few hours. It never did. When I called the office, I was told they couldn't send anyone back until Saturday because they were too busy and didn't have available technicians. That left me wondering: what exactly is "Guaranteed" about Guaranteed Service? I paid thousands of dollars, but my AC still wasn't working. I was told I'd be placed on an emergency cancellation list for Friday. No one ever came or even contacted me. On Saturday, another technician arrived and immediately questioned the previous repair. He showed me the photos from Thursday and explained the first technician had not added enough refrigerant. According to him, the invoice even stated the system was overcharged when, in reality, it was undercharged. He added refrigerant, and I finally thought we'd get some relief. Unfortunately, that didn't solve the problem either. By Saturday night, the temperature in my house never dropped below 72°—it actually climbed to 76°, even though the outdoor temperature had fallen to around 82°. Sunday morning I went outside and found the refrigerant lines and the brand-new valve they had just repaired completely frozen. When I called again, I was told the earliest another technician could come was Monday afternoon. At this point, I'm left asking: - How many days of work am I supposed to miss? - How many technicians does it take to correctly diagnose one AC system? - Where is the urgency after charging someone nearly $4,000 and leaving them without working air conditioning during a heat emergency? I was seriously considering becoming a Guaranteed Service member because of the benefits they described, but this experience has completely changed my opinion. I don't question that the technicians are trying, but the lack of quality control, follow-up, urgency, and accountability has destroyed my confidence in this company. When customers spend this kind of money, they shouldn't have to wait days between visits while living in an unsafe, uncomfortable home. I expected guaranteed service. Instead, I've received repeated delays, conflicting diagnoses, and an AC that still doesn't work. I guess lets see what the techs say on Monday. I will edit this based on my experience.

I called Guaranteed Service to fix a leaky water line for my toilet. They sent me a photo of the technician and let me know when he was on his way. Eric was great. He knew exactly what needed to be done, and fixed the problem perfectly. He applied a $50 coupon without me even asking, and the final price was $128 less than their competitor's quote. Eric was a pleasure to deal with. I highly recommend Guaranteed Service and would call them again. Before and after photos below.

Josh came to my home and did a complimentary AC service. He showed me so much regarding my ac unit. He was very thorough. He showed me how I could get a plan and save money. I ended up getting a plan and Josh took care of the ac unit and took care of my humidifier unit as well. Perfect.

Paul the service technician came and assessed my problem very thoroughly with his state of the art equipment. He explained everything as he went along in laymans terms that was very easy to understand. He answered all my laymans questions very patiently. He gave me a solution to the problem that pointed out the flaws in the other company’s solution that i had consulted with. Anthony and Bashir installed the panel and electric vehicle mgmt system impeccably.

Philip Coppolino was absolutely amazing at explaining everything from start to finish. With what my initial issue & resolution of my chain link light fixture, to thorougly checking out my circuit breakers, the wiring & all the outlets in & around my condo. My condo was built in 1982 & I am the 3rd owner. Unbeknownst to me, that 1 of the circuit breakers was slightly burnt inside ,which he had showed me & how the neutral wiring was not properly installed to their own screws, which I also was shocked to see. Which over time could have been a saftey hazard. He went over everything, thoroughly, and gave me a few options that were available in order for me & my husband to make the best & informed decision especially for the saftey of our home & family! Thank You Philip! So that being said we decided on the option that met our needs. Philip unfortunately didn't have these specific circuit breakers in his vehicle & had scheduled, his colleague Ron Ball to pickup the necessary circuit breakers and other equipment & come to my home to complete the job. Kudos to Ron Ball - Thank You for your prompt & efficiency in completing the job. A pleasure. New Circuit Breakers, Corrected the Neutral Wiring & Replacement of Chain Link Light! Awesome job 👏👍 Very informative & professional & courteous. He completed everything perfectly 👌 Neat & Clean. Thank you for giving us peace of mind.🙏🙏 knowing that their are awesome professionals, as both Philip C. & Ron B. Definitely would recommend Guaranteed Service & will be using them for anything else. Regards, Monique & Marc
