§ 17-105. Heating system efficiency tests. 1. For the purposes of
this section:

a. "Contractor" means any person who contracts to install, repair or
service oil or gas heating systems for customers.

b. "Oil heating system" means a device which burns either No. 2 or No.
4 fuel oil for heating purposes.

c. "Gas heating system" means a device which burns either natural gas
or propane for central heating purposes.

d. "Service contract" means an oral or written agreement between a
contractor and a customer which requires the contractor to service the
customer's oil or gas heating system.

e. "Customer" means any person who resides in, or is the owner of, a
one, two or three-family dwelling or a single unit of a multiple
dwelling, including an individual condominium unit or cooperative unit,
who uses an oil or gas heating system for heating such dwelling or unit
and who is responsible for the operation and maintenance of such oil or
gas heating system.

f. "Efficiency test" means a test of steady-state efficiency and shall
include the following procedures: (1) with respect to an oil heating
system, measuring the carbon monoxide, measuring the carbon dioxide or
oxygen content, measuring the net stack temperature, measuring the smoke
level, and such other procedures as the contractor shall deem
appropriate; and (2) with respect to a gas heating system, measuring the
carbon monoxide, measuring the carbon dioxide or oxygen content,
measuring the net stack temperature, and such other procedures as the
contractor shall deem appropriate.

2. Every contractor who offers to perform service contracts for
customers shall offer to include in such contracts a yearly efficiency
test. Such test, which shall be at a customer's option, shall be
performed after any repairs or adjustments have been completed pursuant
to the service contract, and the additional cost, if any, for such test
shall be separately charged. Upon the completion of any such test, the
contractor shall provide the customer with a form listing the values for
carbon monoxide, carbon dioxide or oxygen content, the net stack
temperature, and the smoke level, as appropriate, and the steady-state
efficiency (expressed in a percentage) determined therefrom.

3. The commissioner shall make reasonable efforts to notify all
contractors of their obligation to offer efficiency tests to customers
as provided by the provisions of this section.
