What Does an AC Starter Actually Do
When an air conditioner compressor begins, it requires 3 to 7 times its regular running current to accelerate the motor from zero to operational speed. For a 1.5-ton split AC, that equates to a starting surge of 15 to 25 amps on a circuit rated for 8 to 10 amps of running current. Without proper management, this surge can trip the MCB, cause voltage dips that affect other appliances on the same circuit, and degrade the compressor motor’s insulation after repeated start-stop cycles.
An AC starter solves this difficulty at the electrical level. It sequences the starting current, lowers the voltage during start-up until the motor approaches running speed, and then returns to full voltage operation. Some starters provide continuous protection against overloads, phase failures (in three-phase systems), and short circuits.
To put it simply, an air conditioner’s compressor is its heart. The starter is the pacemaker that ensures the heartbeat is correct every time it starts.
Types of AC Starters — What a Manufacturing Unit Can Produce
The AC starter market in India includes a variety of product categories, each serving a distinct part of the air conditioning and motor protection industry. A well-organized manufacturing unit can create numerous varieties using the same fundamental electrical assembly setup:
- DOL Starter (Direct On-Line): The most basic version, which connects the motor directly to the power source and provides overload safety. Used for small single-phase and three-phase compressor motors up to 5 HP that can tolerate a starting current surge. The most common starter type for window air conditioners, compact split air conditioners, and single-phase refrigeration compressors. The highest volume corresponds to the lowest unit value.
- Star-Delta Starter: For three-phase induction motor compressors over 5 HP, it connects the motor in star configuration during startup (lowering beginning voltage and current by 1/√3) and transitions to delta mode at running speed. It is used in big central air conditioning systems, chillers, and industrial refrigeration. The unit value is significantly higher than DOL.
- Soft Starter: Uses thyristors (SCRs) to gradually increase the voltage to the motor, eliminating the rapid current surge totally. Offers the smoothest start and the finest motor protection. Used in high-end split air conditioners, VRF systems, and commercial air conditioning. Growing segment as energy efficiency requirements tighten.
- Capacitor Start Relay: Used in single-phase compressor motors, a start capacitor provides the phase change required to generate beginning torque. When the capacitor reaches running speed, the start relay disconnects it. Used in nearly all window air conditioners, refrigerators, and tiny split air conditioners. The residential appliance market has the highest volume per unit count.
- Electronic Motor Protector: Not a starter, but a companion protection device that monitors voltage, current, phase sequence, and temperature to safeguard the compressor. Commercial HVAC installations are becoming increasingly mandatory. A growing segment.
AC Starter Manufacturing Market Opportunity
India accomplished a historic milestone in 2023, when air conditioner penetration in urban households surpassed 20% for the first time. It sounds little, but consider what it means for the remaining 80% of urban households and the entire rural market, which has only recently begun. By 2030, India’s air conditioning market is expected to rise from 1.5 crore to 4 crore units per year. Each unit requires a starter. Every older unit’s starter will ultimately need to be replaced.
The replacement market is especially valuable to a manufacturer. A compressor starter has a typical service life of 5 to 8 years under normal use. India has around 10 crore installed air conditioning systems, which means that 1 to 2 crore starters need to be replaced each year due to natural wear. This replacement demand is unaffected by economic slowdowns or new AC sales data. It flows regardless.
Commercial HVAC represents a distinct and expanding demand source. Hotels, hospitals, office complexes, malls, and industrial facilities employ three-phase compressor starters (star-delta and soft starts) with much higher unit values than residential DOL starters. India’s infrastructural expansion is constantly filling up this commercial inventory.
The Make in India initiative has also provided an opportunity. A significant majority of India’s AC starting components, particularly soft starter PCBs and thyristor modules, are currently imported from China. Domestic producers who can create dependable alternatives are attracting institutional purchasers prepared to pay a small premium for supply chain assurance.

Manufacturing Process — From Components to Finished Starter
AC starter production is essentially an electrical assembly and testing activity; unlike metal fabrication or machining, electronic and electromechanical components are constructed, connected, and tested. This is important for the project report since the bank’s technical appraiser must grasp what “manufacturing” entails for this product.
- Enclosure fabrication: The starter’s metal housing (enclosure) is made of mild steel sheet that has been cut, bent, and drilled before being painted or powder-coated. Standard enclosures with moisture protection ratings of IP54 or IP65. Smaller operations outsource enclosures to sheet metal fabricators, while bigger units manufacture them in-house.
- Component sourcing and quality control: Contactors, thermal overload relays, capacitor start relays, thyristors, PCBs, terminal blocks, and wiring are obtained from suppliers. Before assembly, each batch is tested to ensure that it meets standards.
- PCB assembly (for soft starts and electronic starters): Thyristors, gate trigger circuits, zero-crossing detectors, and protective circuits are soldered onto PCBs, either manually or with a wave soldering machine for larger quantities.
- Wiring and assembly: Contactors, relays, and protective devices are wired inside the enclosure according to the wiring diagram. Connections are terminated on DIN rail-mounted terminal blocks for field wiring.
- Testing: Every finished starter is tested — overload trip current is checked, the starting sequence is tested with a test motor load, and the protective function is verified. Only tested units are packaged and shipped.
- Marking and certification: BEE (Bureau of Energy Efficiency) and BIS marking standards for energy-efficient starters must be met in some product categories. These compliance costs are detailed in the project report.

Frequently Asked Questions
During the startup and operation of an air conditioning system, an AC starter controls and protects the compressor motor. Without a starter, the compressor draws 3 to 7 times its usual running current during startup, tripping circuit breakers and damaging motor insulation over time. The starter regulates starting current, protects against overload, and, in sophisticated models, monitors for phase failure and voltage irregularities.
Yes. Electrical components and control panel production are eligible for PMEGP. Projects up to ₹50 lakh are eligible for 15-35% capital subsidy. CA-certified KVIC-format project report with employment generating section required. Sharda Associates offers PMEGP project reports beginning from ₹2,999.
A DOL (Direct On-Line) starter links the motor directly to the supply — the cheapest and simplest choice, but it applies full power immediately, resulting in a current surge. A soft starter employs thyristors to gently increase the voltage, removing the surge, minimizing mechanical stress on the compressor, and increasing motor life. Soft starts are three to five times more expensive than DOL, but they are increasingly used in commercial and high-end residential air conditioning installations.
DOL and star-delta starters require contactors (AC3 rated for motor loads), thermal overload relays, push buttons and indication lamps, terminal blocks, wiring, and MS sheet metal enclosures. Additional components for soft starts include thyristors (SCR modules), heat sinks, gate trigger PCBs, voltage and current measuring circuits, and digital displays. Contactors and relays are available from distributors in Pune (Chakan), Faridabad, and Mumbai. Thyristor modules are either domestically sourced or imported.
Three distinct buyer channels exist: OEM supply to AC manufacturers (Voltas, Daikin, Blue Star, Carrier, Mitsubishi — who source starters for their assembled units), aftermarket replacement through AC service technicians and electrical component distributors (the largest volume channel by unit count), and project supply to commercial HVAC contractors installing central air conditioning systems in hotels, hospitals, offices, and factories.
Single-phase capacitor start relay (for 1-1.5 ton split AC) costs ₹350-600. DOL starter (three-phase, 5 HP) costs ₹1,200-2,500. Star-delta starter (three-phase, 10-15 HP) costs ₹4,000-9,000. Electronic soft starter (three-phase, 15 HP) costs between ₹8,000-18,000. Prices vary depending on brand, contactor grade, and protection features. Aftermarket channels charge 20-40% more than OEM prices for the identical goods.
BIS certification under IS 13947 is applicable to motor starters in India. BEE (Bureau of Energy Efficiency) energy efficiency branding is needed for starters that come with energy-rated products. For export to European markets, CE marking under the Low Voltage Directive is required. Certification and testing fees must be included in the project's pre-operative expenses.
Rising temperatures, lowering AC prices, and increased middle-class purchasing power are expected to drive India's air conditioning market from 1.5 crore units per year to 4 crore units by 2030. Every new air conditioning unit requires a starter. The replacement market for the 10 crore+ existing installed units adds 1 to 2 crore starter replacements every year. The commercial HVAC segment is growing at a rate of 15% or more as infrastructure expands. The market for air conditioner starters is projected to be around ₹3,000-4,500 crore per year.
Yes, in the aftermarket replacement industry. The aftermarket buyer – an AC repair technician replacing a faulty starter — values availability, affordability, and compatibility over brand. Electrical component distributors will find eager clients for a locally manufactured starter that meets electrical criteria while costing 15-25% less than branded versions. The OEM channel requires lengthier connections and quality certifications to penetrate, whereas the aftermarket is immediately available.
