Former Operations Director,

Mark F. Roling

I have known and worked with Mark Rosales and the great team at ABC for over 5 years while I was at Camarillo Premium Outlets. Their strongest point is their communication, but they also are very engaged with the client on pricing for repairs, new installs, and there is never any “surprises”, everything is approved before completion. They are continuously the low bidder on capital jobs, but never skimp on the quality of their work, or the quality of their people they send out to work with Management.

I highly recommend ABC to anyone, whether it be commercial retail, office buildings, or residential. They are by far the best HVAC company I have ever had the pleasure of working with. In one phrase what you can say about ABS, is… they got my back!

“I am writing this to recommend the services of American Building Comfort, Inc. The company is currently under a two-year contract with the Housing Authority of the City of Oxnard to privde HVAC maintenance services at seven locations. Accordingly, I have no hesitation in recommending them as a company with which to do business.

The customer service received from this company has been excellent; their response to emergency calls has been exemplary. The services technician assigned to our sites continually display expertise and professionalism whether they are performing routing service calls or emergency calls. The president of the company, Mr. Mark Rosales, also works diligently with his clients to make sure that any small problems are taken care of right away and not allowed to become bigger issues.

If you have any further questions or desire additional information, feel free to contact me.”
