The state of California, in conjunction with it's Energy Commission (CEC) made some modifications to the Title 24 requirements, in specific with the condition and installation/repairs/replacement of central heating and air conditioning systems. Starting in November, a check of the air distribution duct work is required when certain changes occur. Ken can now offer the service of a third party verification leak test to help comply with these changes. If this is a service that you need, contact Ken and he will perform the needed testing. For more information, go to the following web site article, distributed by the Energy Commission to determine if your system is in need of this testing.
