A great experience.

Description of Work: Installed Super-high efficiency Energy Star Central heating and air conditioning system with variable speed equipment. This included using Ozone-friendly refrigerant, added duct insulation for greater energy efficiency, and mastic sealing of all fittings to eliminate air leakage.

Review: Thanks again for doing such a great job. The A/C is really quiet and cools the house down very efficiently. I will tell others here at Caltech about the great experience weve had with your company.
