HVAC Systems
NAD Toseeh Paydar supplies HVAC equipment for commercial, industrial and residential projects across Iran and international markets, including chillers, VRF systems, air handling units, rooftop packages and ducted split systems. As a chiller supplier and VRF system distributor working directly with contractors and engineering firms, we match equipment to confirmed load calculations rather than pushing a fixed catalog. Every system is reviewed against the project's actual cooling and heating requirements, refrigerant specification, and installation constraints before a quotation is issued. We coordinate supply timing with contractor schedules and provide technical documentation needed for procurement approval. Use our HVAC load calculator to narrow down system type before requesting a quote, or contact our team directly with your project's specifications for a structured proposal covering equipment, delivery, and installation coordination.
Enter your space's details to get a preliminary load estimate and a matching system-type recommendation, then request a consultation.

Frequently asked questions
Which HVAC system suits my building?
It depends on size, number of zones, installation space and budget: ducted splits for small to medium spaces, VRF for many zones, rooftop packages for large open plans, and a chiller with AHUs or fan coils for large buildings. The site's load calculator gives a first estimate.
Do you also install?
Yes: consulting, sizing, supply, installation and commissioning. See examples on the installations page.
How do I get a quotation?
Fill in the quote form with the building type, area, city and approximate capacity. If you don't have these, start with the load calculator.
