Super knowledgable and helpful. I needed a super quiet unit because it was only a few feet from my neighbor's window. The sales person went through all my options and educated me on noise levels. My new AC works great and you can hardly hear it. Install was professional. I got 5 quotes and Graham was extremely reasonable.

I spoke to Ken today. Nicest man ever!!I was given his number thru a friend. I was getting an air conditioner from another company, my neighbors company,but my friend said I should call ken anyway. Ken went thru my whole estimate with me from the company to make sure I was getting a good unit and price. I mean who does that? He said I got a good price and unit. I am still stunned that he gave me his time and didn't expect anything in return. He was simply helping me out, a person he doesn't know . He will be my first call next time ! I love kind people!

We just had a new heater, new air conditioner and new duct work done, and Ken, Greg and Ricky were so wonderful to work with. We really liked the fact that everything was done with precision and we liked that it did not feel like a rushed install. All questions were answered and everyone was very helpful. We are so very happy to have an A/C unit right now! Thank you Ken, Greg and Ricky :

I just had a new heater installed by Greg and Rick. I could not be more impressed by there work, cleanliness and courteous attitude. They were prompt and quick. Ken was also very helpful suggesting which model would work best for me. I will definitely recommend them.

Perfect service experience. Dale was our technician, he was very professional, friendly, knowledgeable and competent. He called beforehand, was on time for the appointment (I was the first call of the day Any service tech can run behind depending on other customers issues before an appointment, it is to be expected), had us fixed and working quickly. I'm very pleased with the service, the fee, and Dale's work. Very happy to have a local company servicing our units.

We are extremely pleased with the new Carrier gas furnace and air conditioner purchased and installed in our home in Orange in August, 2015, by Dependable Graham. We were replacing a 30 year old system originally installed by the homebuilder. Sales Engineer, Ken, was very friendly and professional. He assessed the situation, made recommendations and gave us options.

No hard sell. Our installation was promptly scheduled and the installation team of Greg and Erik arrived as scheduled. Both Greg and Erik were friendly, experienced and knowledgeable. They took the time to make sure the installation was done correctly and kept us informed of each step of the process. They also took the time to make sure the system worked properly and we understood how it operates. The system works great. All were super people and a pleasure to work with. We highly recommend Dependable Graham.

We recently had air conditioning installed in our home in Huntington Beach. We went to Dependable Graham because they had installed our heating about three years ago and did an excellent job. Our house is about 3000 square foot and since it was not plumbed for air conditioning it was a more difficult job to tackle. Dependable Graham sent out very professional people who installed our air conditioning in approximately 2 1/2 days.

We were surprised at how the installation did not affect the aesthetics of our home. The representatives were compentent and courteous. When they left there was absolutely no mess to clean up. We would definitely use this company and highly recommend them if you are needing a air conditioning or heating system.
