Reviews
Write a ReviewShopped out multiple heat pump quotes for our Dana Point home before settling on CCS. CCS were were timely in their response, accessible, and always helpful throughout the entire process. We discussed multiple options at different price ranges before settling on a 3.5-ton AC-Pro system, which Eric Tesch (CCS Business Owner), and his crew installed the new unit on-time, and on budget. We had a couple of hick-ups during the install, including electrical connection issues, and an unanticipated, re-sizing of the attic entry to remove the existing furnace/air handling unit. This caused added time and effort to complete the project, but Eric was both helpful and fair in addressing these issues. Before settling on CCS I called and spoke with multiple, past clients, who all provided reassuring referrals. The system installation was completed more than several weeks back. Overall I feel our experience with CCS was very positive and would definitely recommend them to others.
Exceptional service and efficient too! I’m So happy we decided to use Coastline to install a new heater and air conditioning unit. Couldn’t be happier with the results.
Thank you so much, it was a pleasure working for you!
great work and value. Eric, Jack and Ricky completed a full system within a day.
Sandy and Eric and their team have been excellent... they gave me multiple options to address my HVAC issue. They lived up to the promise to be responsive when I had an issue with my system and installed a new unit at a good price. I am very happy to have found them.
Thank you so much, it's a pleasure working with you!
Eric and his son did an awesome job!
I did some Facebook research on HVAC providers in the Lake Forest/RSM area and Coastline came with the highest recommendations. The recommendations were spot on. Eric was very professional, very knowledgeable but most important for me: very honest. I highly recommend Coastline for your HVAC needs.
It was our pleasure helping you!
Great service
Very friendly, professional, an efficient.
Punctual, took time to show me the problem. Reasonable estimate for replacing heater. Showed up at scheduled time with new one. Replaced old heater, removed all trash. New heater works well. Highly recommend them!
Exactly what I needed when I needed it. Eric and his team were very professional, the cost was reasonable and everything was done according to what was promised. What impressed me the most, however, was Coastline's responsiveness. Any question, any request was met with an immediate response. These days, that kind of thing is so rare. I really appreciated the attention I got from Coastline.
Thank you. We truly value your business!
