4.5 Chris N. Dan Point, CA

Shopped 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.

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.

5.0 Elias T. Google Review

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.

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!

5.0 Tom Hackleman Google Review

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.

Response from Company:

Thank you. We truly value your business!

  1. Verify Trade License
    HomeAdvisor checks to see if the business carries the appropriate state-level license.
  2. Verify Insurance
    As a part of our screening process, we encourage professionals to carry general liability insurance. We require coverage for hundreds of services.

    For business types that require a Secretary of State filing, we confirm that the business is in good standing in the state in which it is located.
  4. Criminal Records Search
    HomeAdvisor uses 3rd party data sources to conduct a criminal search for any relevant criminal activity associated with the owner/principal of the business.
  5. Sex Offender Search
    We confirm that the owner/principal is not listed on the official state Sex Offender web site in the state in which the owner/principal of the company is located.
  6. Bankruptcy Search
