“I was and always have been, happy with the service from Chas Roberts. Chas Roberts was the company of choice by our home builder Presley Builders, 30+ years ago and it is still my choice! Thanks for keeping a good thing going!”

“The Chas Roberts Technician, Hector, serviced our HVAC. He was very professional, courteous and respectful of our home. He kept us informed on the progress of the repair every step of the way. Hector also gave us tips to ensure the system continues to run properly. He did an excellent job and we are very satisfied with the results. In the future we would like Hector to be our technician.”

“Had two visits from Chas. Both techs were knowledgeable, thorough, and friendly. I did not feel pressured to get services I did not need. Great service. I will go through Chas Roberts when it is time to replace my aging unit.”



“Cannot say enough good things about the emergency service I received from Chas Roberts today! From my panicked phone call for help with a leaky water softener and amazingly professional scheduling help……to Luis Estrada’s arrival, quick assessment of the issue with a short term fix and long term solution; this is one happy customer. Water flooding into my garage was a nightmare scenario and Chas Roberts came thru with dream team assistance! From now until the end of time, for regular maintenance for my A/C and plumbing needs and those crazy emergency instances too, I will ALWAYS choose Chas!”



“We had our annual heating system maintenance service on Monday, September 28, 2015.
Your technician, Jesse, was very professional and thorough in performing his job. He also changed our air filters for us. Chas Roberts continues to provide us with very good service. We do not hesitate to recommend Chas Roberts when someone is looking for a company to service their AC and heating units.”

“Hello – Just wanted to let you know that “Roberto Lizarraga” has just left our home after coming out for an AC check arranged through Home Depot. He called us 30 minutes before hand to notify us of his intended arrival. He arrived on time, introduced himself, and presented his card. He was very polite, took time to listen to our concerns, explained what he was doing and why and very thoroughly explained the problem and possible solutions. Although Roberto told us what we did not want to hear, that we needed a new unit, we were not surprised, and he did so in a very professional manner. We asked a lot of questions, and he patiently answered each one. In general, I find people quick to criticize and complain when service is poor or not what they expected, but rarely offer compliments when service is good. So I would like to say that we were very impressed with Roberto and his service met and exceeded our expectations. Thank you so much.”

“Jose was outstanding and very good at explaining what needed to be done and what he did. He is another in a long line of Chas Roberts employees who ably represent your company…that is why we continue to use Chas Roberts!”



“Emir did an outstanding job in checking my furnace today to make sure it was working properly. I have been a regular customer with Chas Roberts since 2002 when I purchased the new home that they had installed the HVAC system for Shea Homes. The level of customer service over the years has been “world class.” Starting with the scheduling of the appointments through the final contact with the service technician has been excellent. They do what they say they are going to do, and I have never had any issues requiring a call back visit to complete something that should have been done on the initial visit. The level of professionalism with their technicians has also been off the charts. They are very timely in meeting the arrival window of time, and are always polite and willing to answer any questions about what they found and how they fixed it. Service truly is Job # 1 with Chas Roberts. Thanks!!!

I have been dealing with your company for about 4 years and I think you are the best. Every technician I have come in contact with has shown expertise and professionalism and always gets the problem solved the first time. I will continue to use Chas Roberts in the future. Thanks for being a company I can count on.”
