HVAC during Construction Clause Samples
The 'HVAC during Construction' clause outlines requirements for the use and operation of heating, ventilation, and air conditioning systems while construction is ongoing. Typically, it specifies whether the permanent HVAC system may be used to condition the building during construction, under what conditions, and who is responsible for maintenance and cleaning if it is used. For example, it may require the contractor to protect the system from dust and debris or to perform duct cleaning before project completion. This clause helps prevent damage to HVAC equipment and ensures indoor air quality is maintained, thereby reducing future maintenance issues and disputes over system performance.
HVAC during Construction. If air handlers are used during construction, the Lessor shall provide filtration media with a MERV of 8 at each return air grill, as determined by the latest edition of ASHRAE Standard 52.2, Method of Testing General Ventilation Air Cleaning Devices for Removal Efficiency by Particle Size.

If air handlers are used during construction, the Lessor shall provide filtration media with a MERV of 8 at each return air grill, as determined by the latest edition of ASHRAE Standard 52.2, Method of Testing General Ventilation Air Cleaning Devices for Removal Efficiency by Particle Size. The permanent HVAC system may be used to move both supply and return air during the construction process only if the following conditions are met:
1. A complete air filtration system with 60 percent efficiency filters is installed and properly maintained;
2. No permanent diffusers are used;
3. No plenum type return air system is employed;
4. The HVAC duct system is adequately sealed to prevent the spread of airborne particulate and other contaminants; and
5. Following the Building “flush out,” all duct systems are vacuumed with portable high-efficiency particulate arrestance (HEPA) vacuums and documented clean in accordance with National Air Duct Cleaners Association (NADCA) specifications.
HVAC during Construction. If air handlers are used during construction, the Lessor shall provide filtration media with a Minimum Efficiency Reporting Value (MERV) of eight (8) at each return air grill, as determined by ASHRAE (American Society of Heating, Refrigeration and Air- Conditioning Engineers) (52.2-1999, HVAC Use During Construction). The permanent HVAC system may be used to move both supply and return air during the construction process only if the following conditions are met:
1. A complete air filtration system with 60 percent efficiency filters is installed and properly maintained;
2. No permanent diffusers are used;
3. No plenum type return air system is employed;
