I was so impressed with the excellent customer service provided by Guaranteed Quality Restoration, Inc.. I was going through some remodeling and my contractor had disconnected my A/C unit. I was without a running A/C unit from winter through July. After many pleas to my contractor to connect my A/C system as I had medical issues being subjected to extreme heat, I still had no running A/C unit. It was now July 2014. I had no choice but to hire a air conditioning company to connect my A/C condenser unit. Many A/C companies could not provide service to me right away due to their heavy summer workload. However Guaranteed Quality as busy as they were was empathetic to my needs and I had my A/C up and running within a couple days from my initial contact with Guaranteed Quality. Jake, Guaranteed Quality’s A/C technician has shown exemplary skills and expertise in his field. He was able to install dampers to balance the air flow throughout my house as I had a problem with some rooms being cold and other rooms not getting enough ventilation/circulation. Jake did an awesome job professional and pleasant. Donnie, Anthony and Larry had been just great. They were all superb with a great clean up job too. Dave and Martin in scheduling did a wonder job coordinating the work being done at my home. I highly recommend Guaranteed Quality Restoration, Inc. as from my experience they exemplify and live up to their company’s name “Guaranteed Quality”. But more so they are about their customers.

We suffered for weeks with our air conditioner. We live in a very hot valley, near Rialto. The company I had come out charged me to fix the air conditioner but it was never cold. Never worked right. Guaranteed Quality Heating and Air found the problem right away and we are comfortable for the first time in weeks. Thank you for helping us with good quality service. ~ Lena C. (San Bernardino)  

My mom had been suffering with a terrible air conditioner for many years. When my sister and I went for a recent visit, we were saddened that the a/c was barely working.We called GQ and they were not only fast, but very reasonable. They didn’t try to sell my mom anything she didn’t need and they took such good care of her we couldn’t wait to tell the world what a great service they offer. THANK YOU GQ ! Cole T. (Newport Beach)   They came out for our AC Repair at our home in Irvine … gave us a price. Didn’t try to upsell us. We loved the service and the PRICE. THANK YOU … finally, a contractor you can trust. Marianne T. (Irvine)   We were very pleased with the work performed. They were on time, professional, and worked very efficiently. Most importantly, the bad odor coming from the vents is gone after your crew cleaned my air ducts. ~ Mrs. A.(Laguna Hills)
