Air Conditioning Permit Requirements The on-line permit is available for properties in Sunnyvale with a residential zoning district of R-0 or R-1 and for condenser units that will be installed on the ground (not roof top location). is available on-line by clicking on E-Zoning. This permit will allow a new or replacement air conditioning unit. No planning permit is required for air conditioning units. The standards listed below are verified through the building permit process. The condenser unit shall meet the zoning district setbacks for the property. For all residentially zoned properties, the minimum rear yard setback is 10 feet. For properties in the R-0, R-1.5 and R-2 Zoning Districts, the minimum side yard setback is 4 feet. All other residential zoning districts require a 6 foot minimum side yard setback. Corner lots must have a 9 foot setback along the longer street frontage. You may obtain the Zoning District for your lot on-line by clicking on E-Zoning or by contacting a Planner at the One-Stop Permit Center.

All air conditioning units must meet the noise standards of Sunnyvale Municipal Code Section 19.42.030. ac units to buyNoise shall not exceed 50 dBA during the hours of 10:00 p.m. and 7:00 a.m. or 60 dBA during 7:00 a.m. and 10:00 p.m. at any point on adjacent residentially zoned property.should you cover your air conditioner unit in the winter All air conditioning units must be screened on all four sides. central air conditioner best priceIn most cases, air conditioning units located in private yards meet this requirement. If the proposed air conditioning unit is located on the roof, on a corner lot between the fence and the street, or in private homeowner’s association area, please speak with Planner regarding the required screening.

A permit is required to install a new residential air conditioning unit and for the replacement of existing air conditioning units. Permits are required prior to installation or replacement of air conditioning units. Following is a listing of the general requirements based on the 2013 California Electrical Code, 2013 California Mechanical Code, 2013 California Plumbing Code, 2013 California Energy Efficiency Standards and the Sunnyvale Municipal Code. This brochure is intended to provide general information, contact the Building Safety Division for any questions or additional information. Duct Air Leakage Test - An air leakage test, performed by a HERS rater, is required for existing ducts. At the final inspection, the CF-3R form completed by a HERS rater is required to be provided to the building inspector. A listing of certified HERS raters may be found at: http://www.energy.ca.gov/HERS/providers.html Condensing Unit Efficiency - The condensing units for permits issued through December 31, 2014, shall be a minimum of 13 SEER.

Permits issued on or after January 2, 2015 shall have condensing units rated up to 45,000 Btu/h shall have a minimum efficiency rating of 14 SEER and 12.2 EER. Larger units shall have a minimum 14 SEER and 11.7 EER. Disconnect - An electrical disconnect for the unit shall be provided within sight of the unit and readily accessible (not mounted behind the unit). The main electrical panel shall be labeled with the circuit for the new equipment. (CEC Articles 440.11, 440.14, and 408.4) Slab or platform - The condenser unit shall be located and secured to a minimum 3 inch thick slab or approved platform. Condensate Drainage - The condensate line shall drain to a landscaped area or to the sanitary sewer line. (CMC 1106.10 and SMC 16.24.040) Receptacle - Provide a 15 or 20 amp receptacle at an accessible location within 25 feet of the condenser unit. If located outside, the receptacle shall be GFI protected and in a weatherproof cover (bubble cover). (CEC 210.63, 210.8, and 406.8).

Insulation - Insulation on the suction line (cooling refrigerant line) shall be protected from physical damage or ultraviolet deterioration by an aluminum or metal shroud, paint, plastic cover, or ultraviolet resistant tape. Refrigerant Port Protection - The refrigerant circuit access port shall be protected from unauthorized access with a locking-type tamper resistant cap. Clearance to Clothes Dryer Vent - When located outdoors, the condensing unit shall be a minimum of five feet from the termination of a clothes dryer vent. The Air Conditioning Permit is NOT available on-line if you are: Not installing the condenser unit outside on the ground. If the property is part of a Homeowner's Association (HOA). If any of the above conditions apply, the permit shall be issued at the One-Stop Permit Center, City Hall, 456 W Olive Avenue. is available at the Building Division web site. A final inspection should be scheduled after all work is complete.

conditioner gauges is chamber device that is design to control the flows ofIt holds both compound and high pressure. refrigeration manifold gauges look like: manifold gauges set have the three chambers: the low pressure chamber (left side), utility chamber (middle), and the high pressure chamber (right side). connect the HVAC manifold gauge to the air conditioner units, he connects the low pressure side of air conditioner unit to low pressure gauge side. to read the pressure in discharge line he connects the high pressure gauge hose to the air conditioner high pressure side. utility port (the middle chamber) is a place where we connect the hose to vacuum pump, recovery units or the port to add or remove refrigerant from ACAir conditioning gauges is used to measure air conditioner units pressure within closed-system to evaluate or troubleshoot theGauges manifold set is the most frequently used item when it comes to refrigerant or pressure.

conditioning gauge set allows the HVAC technician to check central air conditioning unit operating pressures, transfer Ac refrigerant, pressure test system, purge the system with nitrogen, and perform other gauges manifold set includes the hoses, the manifold, the valves, the compound gauge (low pressure gauges) and high pressure gauge. learn how air conditioning gauges work from two-valve gauges (like the AC gauge picture above) and from a R-22 manifold gauge set. air conditioner gauges work is by open and closing the hand valve. can see in AC gauge assembly above, it has needle and small port to the utility chamber from both high and low pressure chamber. needle and small port allow the refrigerant to flow from low pressure chamber to utility chamber or across from low pressure chamber to high pressure the low pressure hand valves, we have to turn it counterclockwise. is the low pressure port to the utility chamber and to close the low pressure
