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.

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 :

We have been repeat customers of Dependable Graham for decades now. They have always provided timely, thorough and competitively priced services on new equipment and maintenance. And, they have been pleasant people to work with. Don Jones

This might be the most honest company ever. Came out to inspect for a job I wanted done, told me I didn't actually need it and should just switch to a larger filter that can be bought at Home Depot. Also recommended another company that could do duct work and they did a great job too. Very impressed with how they conducted themsleves, and when I *do* need HVAC work in the future, I'll call them first.

Oh my! Just in time for the 100 degree heat in October! The heat never ends it seems! I just bought a house on Balboa Island and was hesitant to spend the money on air as we should have a bay breeze. I quickly realized that I was living in a hot box! I got a very quick and fair quote from the team. They had my air installed in a week, just in time for the heat wave! I am so so happy with this company! Honest people! A plus, plus, plus!

Our heater stopped working right as the weather started to get really cold, and during thanksgiving break. I called and even though they were super busy they got someone out in a couple days. He was right on time and found the problem and fixed it right away for a reasonable price. He made sure filter was clean and thoroughly explained what had gone wrong. Our serviceman was Dale B. Very happy with this company, I will call them again for sure

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.
