TRADEPRO TP-5 Hard Start Kit - 1/3 HP to 2 HP HVAC Compressor Booster

The TRADEPRO TP-5 is a high-performance hard start kit engineered to provide an essential electrical torque boost to residential and light commercial HVAC compressors. By significantly increasing the starting torque, this component helps the compressor overcome high head pressure and internal mechanical friction, ensuring a rapid and reliable start every time the thermostat calls for cooling.

Technical Performance

Designed for systems ranging from 1/3 HP to 2 HP, the TP-5 utilizes a specialized "Two-Wire" configuration that allows for a non-polarized, direct connection to the existing run capacitor. As a Genuine TRADEPRO performance upgrade, it features a high-capacity start capacitor paired with a solid-state relay. This relay precisely senses the motor's speed and automatically disconnects the start circuit once the compressor is running, protecting the sensitive internal windings from electrical stress and overheating.

Key Features and Function

Feature 1: 300% Start Torque Increase – Reduces the duration of high-amperage "locked rotor" starts, significantly extending the life of the compressor motor.
Feature 2: Universal Two-Wire Installation – Simplifies service calls with a fast, two-lead connection; no additional wiring or mounting brackets are required.
Feature 3: Solid-State Cutout Technology – Integrated sensing ensures the capacitor is only active for the exact millisecond needed to initiate rotation.
Feature 4: Low-Voltage System Support – Ideal for units operating on long wire runs or in areas prone to summer voltage drops (brown-outs).

🛠️ HVAC Depot Pro Tip: The "Small System" Specialist

While the TP-6 is for larger units, the TP-5 is perfectly tuned for 1-ton and 1.5-ton systems, as well as many large reach-in coolers. Using a "too powerful" hard start on a small compressor can actually stress the bearings, so the TP-5 is the professional choice for smaller residential split systems and heat pumps.

Cross-Reference & Compatibility

The TP-5 is a universal service component and a direct alternative for:

OEM Numbers: TP5, TP-HS5, HS5
Industry Alternatives: Supco HS5, SPP5, DiversiTech HS5, Mars 32701
Applications: Compatible with Reciprocating and Scroll compressors found in 12,000 to 24,000 BTU systems.

Extensive Model Compatibility List

1.0 Ton Units: Fits all major brands including Trane, Carrier, and Goodman.
1.5 Ton Units: Ideal for residential condensers and heat pump sections.
2.0 Ton Units: Max capacity for the TP-5 (Use TP-6 for 2.5 to 3 Ton systems).
Refrigeration: Fits most commercial 1/3 HP to 1 HP reach-in compressor types.

Happy Shouts From Our Thrilled Customers

William Bartlett

Cecil really saved me with troubleshooting tips over the phone. Thought I was going to have to replace the blower motor and ended up only needing a motor run capcitor. Thank you and God bless!

Verified Buyer

Riley Connolly

Cecil and Fidel were absolutely amazing and so helpful. We were happy they were open on Sunday, but was impressed with their knowledge and willingness to make sure we had everything we needed. If you need parts or service or install, I would recommend.

Verified Buyer

Cole Meger

Our AC went out during the hottest stretch of summer, and with a one-year-old at home, we were desperate for a quick fix. These guys came through big time — not only did they source the part faster than anyone else in the area, they also walked me through DIY troubleshooting while I waited. Trustworthy, knowledgeable, and run by a solid local family. As someone who owns rental properties nearby, I’ll be sourcing all my HVAC parts from them moving forward. Highly recommend!

Verified Buyer

Carl T. Droste

Had a power outage last night and during the 100 degree heat today noticed that the AC was not blowing any cold air. Pulled the capacitors to have them checked and also took video of the relay making noise even with the breaker was off. The proprietor and her staff were very friendly and helpful. She had the video analyzed and confirmed something was wrong. She checked one of the capacitors was a little low. Capacitor replacement is the biggest ticket item for HVAC repair. It is hundreds of dollars with the a capacitor only about $20.

Fuzzy Wuzzy

Cecil and his family have been a life saver. I walked in with very little knowledge on parts let alone how to repair my unit. All I had was my brother in FL who knows more than I do and Cecil at HVAC Depot. With 2 young kids at home I couldn't afford to wait for a HVAC tech. Cecil walked me through what I needed to know, even after hours when the shop closed. I successfully repaired the fan motor and replaced the capacitor. Thank you HVAC team for being totally awesome. Prices were amazing and I'm forever going to support this small family business. You and your family are what Texas is all about!!!

Verified Buyer

Linda Robinson

I called HVAC Depot and was absolutely blown away by the fast, courteous and exceptional service. They were very knowledgeable about explaining what they were doing and what had happened to the ac system. If you ever need a HVAC team they are best and they won’t hesitate by coming out and they won’t leave until you are happy with the service. Thank you so much for your excellent service. Kudos to you Michelle for your amazing customer service.

My AC went out in our home on Friday night. I went out and got the capacitor details and took them here first thing Saturday morning. Lady at the counter was friendly and had the capacitor I needed! When I got home, I installed the capacitor and AC is all good!!
