Contactor: HVAC Tools & Prices

HVAC tools for the work in front of you.
Compare listed refrigerant prices, find suppliers and keep your field information together in Contactor.

CALCULATE WITH CLEAR INPUTS
Open calculators for superheat, subcooling, airflow, static pressure, electrical values and unit conversions. See the inputs, units and results so you can review each calculation in context. Check assumptions and follow the equipment documentation for the job.

FIND SUPPLIERS AND LISTED PRICES
Browse nearby supplier information and compare published R-22 and R-410A quotes. Supplier coverage varies by location; listed prices and availability depend on the information provided and may change. Pickup requests are available only with participating suppliers that support bookings. Confirm details directly with the supplier.

LEARN AND FIND REFERENCE MATERIAL
School brings guided HVAC lessons, explanatory quizzes and EPA Section 608 practice questions. EPA material focuses on United States requirements; practice does not issue certification or replace an approved exam. The manual library shows model, region and revision details with source links; check that a document applies to your equipment.

KEEP FIELD WORK ORGANIZED
Use equipment records, visit drafts, readings, checklists and service notes in Field desk. Prepared offline copies require setup beforehand. Keep the details you need for a later visit together instead of relying on memory.

ASK AND DISCUSS
Optional AI Support can help structure a question about symptoms, models and readings. It requires a connection, relevant access and consent; answers can be wrong. The forum provides a place for questions and field discussions.
