R.C. Mechanical uses the Whole House Approach to find problem areas in your home. Problems like faulty duct work, improperly sized or inefficient equipment, and poor insulation can contribute to problems with comfort and air quality. A Whole House Comfort Checkup will check these issues and more to ensure your new system will operate at peak performance. Sal Contreras, owner of R.C. Mechanical, is certified by the Building Performance Institute (BPI). Sal personally supervises every R.C. Mechanical installation. BPI uses tests devised by the American National Standards Institue (ANSI) to certify a high level of skill in the field of whole house systems. R.C. Mechanical Inc. is based in Redwood City, CA.
