"Ali came over to our home when we called with a concern of the air flow in our central air conditioning system. He checked the return, the air flow, the temperature at all of the vents, and the entire system. It had more to do with the age of the system and gave us suggestions on how a different filter could increase the air flow. He did all of this and refused to take any money for his time. He is a true honest professional and someone that we would recommend to everyone."

"The person that showed up is the owner. He diagnosed the problem with my central air conditioning system, was a clogged filter due to sanding spackle. Could have charged the system or fed me a bunch of lies but instead was perfectly honest, charged me an inspection fee only and buttoned everything up. I was shocked. Great guy and knows his stuff. Would definitely recommend him."

"Kevin was great! The rest of the company not so much. Kevin diagnosed the problem immediately as the thermostat, had a replacement in the truck, and completed the installation of the new unit quickly. He showed me how to program the updated version, and everything seemed to be fine - until the next morning. Turned out the replacement was defective. When I called, I was told that they might not be able to get back to me that day, but Kevin interrupted his schedule to come back and put in a new (and working) unit at no charge."

"Ralph was very knowledgeable about gas conversions and I felt very confident hiring him. He was great at emailing or calling me back when I had questions before and after the installation. He is very neat and careful about doing things properly."

"Thank you, C&A! The owner and crew were professional, knowledgeable, on time and worked hard all day. They replaced an entire central air conditioning system and did a great job at a competitive price. They left their work area spotless. I recommend them unconditionally!"

"The entire experience from the discussions with the company rep Scott O, to the completion of the installation was excellent. The installers were courteous, knowledgeable and efficient. The Mitsubishi unit itself is an excellent product. Cools quickly, quietly, and is multifunctional. The installers Brian and Moses did the job in a courteous, knowledgeable and efficient manner. All stages of the job went smoothly. Functions of the unit and use of the remote were explained thoroughly and a booklet was provided that reinforces the information. Cleanup was excellently done. I am very pleased with the communication with Scot O choosing the product to be installed, getting questions answered as well as with the knowledgeable, courteous and efficient installers. I highly recommend Elm Air Conditioning."
