HVAC

A furnace won't run without a filter, a duct system won't move air without the right fittings, and a thermostat that's wired wrong won't call for heat or cool at all. Coburn Supply stocks HVAC supplies for jobs at every stage: new installs, mid-life repairs, and the routine parts that keep a system running between service calls. Contractors working residential jobs will find filters, line sets, and HVAC accessories for units already in the wall or attic. Property managers overseeing multi-unit buildings or mechanical rooms will find commercial HVAC equipment sized for larger loads.

HVAC

System Equipment & Core Assemblies 

Furnaces, air handlers, condensers, mini-splits, and duct components make up the core HVAC equipment and supplies in this section, covering residential split systems, packaged units, and commercial setups for properties of different layouts. 

  • Single Parts or Package Orders 
    Replace a single failed capacitor or group of matching condensers, furnaces, and indoor coils together for a full system replacement; ask your Coburn rep about total package availability. 
  • Fits Tight and Small Spaces 
    Compact ductless air handlers and low-profile furnace cabinets fit attics, historic homes, and narrow utility closets where standard air handlers will not clear. 
  • System-Matched Connections 
    Both single-stage and variable-speed systems are stocked, so you can match new HVAC accessories to your building's existing high-voltage or low-voltage connections. 
  • Parts for Existing Systems 
    Replacement contactors, blower motors, fan blades, and control boards are available for units already installed, so a single electrical failure does not require a full replacement.

Products Grouped by System Application

  • Heating, Cooling & Temperature Control
    Gas furnaces, air conditioner condensers, heat pump units, ductless mini-splits, and commercial HVAC equipment.
  • Air Movement & Duct Network Parts
    Rigid sheet metal ducts, flexible insulated runs, supply registers, return grilles, and HVAC ductwork supplies.
  • Installation Components & System Maintenance
    Thermostats, condensate pumps, copper line sets, filter racks, and specialized HVAC installation accessories.

Key Field Specifications & Planning Steps

  • Physical Sizing & Access Clearances
    Measure equipment pad footprints, closet door frames, and duct opening dimensions precisely, allowing clearance for service panels and airflow.
  • Power Utility & Fuel Supply Specs
    Confirm whether your space uses 208/230V single-phase power, 460V three-phase service, natural gas supply, or liquid propane connections.
  • Airflow Capacity & Static Pressure Matching
    Match air handler CFM ratings and tonnage to your building's static duct pressure and regional heat load demands.
  • On-Site Prep & Mechanical Needs
    Check if your project requires line set brazing, electrical disconnect swaps, system vacuum purging, or crane service for rooftop placement.
