What You Need to Know About HVAC Supply Parts from Technical Hot and Cold Parts

When the temperature outside starts to fluctuate, it's crucial to rely on your heating and cooling systems. Nothing is worse than experiencing a breakdown during a heat wave or frigid temperatures. Technical Hot and Cold Parts understands the importance of keeping your system functioning optimally and offers a comprehensive range of OEM HVAC supply parts to maintain your system's performance throughout the year. Explore our extensive selection of HVAC supply parts and accessories, or contact our specialists to find out what you need to get your system working efficiently again.

 

Air Conditioner Replacement Parts and Accessories

Air conditioner parts are designed for longevity, but they can become damaged or worn and require replacement. Some common parts and accessories you may need for your air conditioner system include:

  • Air Conditioner Drain Products: Drain lines on your AC unit can become clogged and may need replacement or cleaning.
  • Plenums & Filter Boxes: Distribute fresh air into your home.
  • AC Evaporator Coils: Remove heat from the air using refrigerant.
  • Condenser Coils: Hold refrigerant in its liquid form.
  • Compressors: Circulate refrigerant through the system.
  • Refrigerant: Absorbs heat and provides cooled air.
  • Expansion Valves: Remove pressure from the liquid refrigerant, allowing it to turn back into a vapor.
  • Equipment Pads: Support the exterior unit of the system.
  • Dehumidifiers: Remove excess moisture from the air when humidity levels are high.

 

Furnace Repair Parts and Accessories

Many furnace parts work together to ensure proper and efficient operation. Commonly replaced furnace parts include:

  • Pilot Light: Burns constantly to ignite the gas when the furnace turns on.
  • Thermocouple: Detects if the pilot light is on and signals the gas valve to open.
  • Hot Surface Igniter: Replaces the pilot light in newer furnaces.
  • Flame Sensor: Ensures there is heat from the igniter, shutting off gas if not.
  • Gas Valve: Adjusts gas pressure entering the furnace.
  • Burners: Mix gas and air to create a flame.
  • Heat Exchanger: Holds gases when fuel is burned, transferring heat to the surrounding air.
  • Draft Inducer Motor: Expels toxic air formed during combustion.
  • Pressure Switch: Ensures the draft inducer motor is on; otherwise, it stops gas flow.
  • Blower Motor: Pushes warm air through the duct system.
  • Capacitor: Starts and keeps the blower motor running.
  • Vent Kits: Remove toxic gas from the system.
  • Gas Piping: Delivers natural gas to the furnace.
  • Zoning & Dampers: Control where the warm air travels.
  • Humidifiers: Add moisture to reduce dryness in the home.

 

HVAC Supply Parts Replacement and Accessories

HVAC systems utilize many of the same parts and accessories as air conditioner units and furnaces. Additionally, complete HVAC systems include parts such as:

  • Thermostats: Control home temperature by signaling the heat or cooling system.
  • Air Filters: Trap dirt, debris, and allergens, with HEPA filters also trapping bacteria and viruses.
  • Grille Covers: Cover HVAC system return vents.
  • Air Purifiers: Remove small particulates to improve indoor air quality.

 

Heat Pump Repair Parts and Accessories

Heat pumps share components with air conditioning systems and furnaces, such as compressors, condensers, expansion valves, evaporator coils, blower motors, and equipment pads. They also include:

  • Accumulator: Stores refrigerant to prevent imbalance.
  • Crankcase Heater: Prevents refrigerant migration and condensation.
  • Reversing Valve: Controls refrigerant flow direction.

 

Mini-Split Repair Parts and Accessories

Mini-split systems use the same coil parts, fans, and motors as other AC systems in their outdoor unit and also include:

  • Air Handlers: Indoor components delivering cooled or heated air.
  • Copper Tubing: Carries refrigerant from the outdoor unit to indoor handlers.
  • Remote: Controls each air handler.

 

Major Components of HVAC Systems

 

Heating System Components

Heat pumps provide both heating and cooling with three primary components: the condenser, compressor, and evaporator. In heating mode, refrigerant circulates to the heat source as gas, then transitions to liquid before returning to gas to distribute warmed air via the blower motor and ductwork.

 

Furnace Components

Furnaces produce warm air with components responsible for starting, heating, and distributing air. The thermostat signals the gas valve to open, allowing gas flow. The burner heats the heat exchanger, transferring heat to the air, which the blower motor circulates through the ductwork until the thermostat signals to stop.

 

Air Conditioning System Components

Four components work together to deliver cooled air: the evaporator coil absorbs heat and humidity, the compressor pressurizes refrigerant, the condenser coil releases heat, and the expansion valve turns refrigerant into a cold mist, restarting the cooling process.

 

Dual-Function Components

The heat exchanger transfers heat for both heating and cooling, turning heat into cool air for air conditioners and warming indoor air for furnaces.

 

Key HVAC System Parts

HVAC systems combine heating, ventilation, and air conditioning. A complete system includes:

  • Heating System: Natural gas furnace, boiler, or propane system, connected to the water system.
  • Ventilation System: Air handler and ducts carrying air.
  • Cooling System: Air conditioner providing cool air and reducing humidity.

 

Efficiency Ratings and Common HVAC Problems

 

SEER Rating

The Seasonal Energy Efficiency Ratio (SEER) measures an air conditioning system's efficiency, comparing cooling output to energy usage.

 

Common HVAC Issues

  • Dirty Filters: Restrict airflow, straining the system.
  • Pilot/Ignition Problems: Cause delayed ignition or short-cycling.
  • Thermostat Malfunctions: Lead to system start failures.
  • Worn Belts and Bearings: Cause airflow issues.
  • Unusual Noises: Indicate bad bearings or failing motors.
  • Dirty Coils: Reduce efficiency.
  • Blower Problems: Indicate relay or circuit board issues.
  • Leaks: Result from clogged drain lines.

 

Comparing Air Conditioners and Heat Pumps

While both cool homes, only heat pumps can reverse to heat a home by absorbing outside heat and transferring it inside. Air conditioners require a furnace for heating.

 

Common Heating and Cooling Systems

  • Split Systems: Separate heating (furnace) and cooling (AC) units controlled by one thermostat.
  • Packaged Systems: Combined heating and cooling components in one unit, suitable for small spaces.
  • Zoned Systems: Control temperature in different areas with automatic dampers.
  • Ductless Mini-Splits: Exterior system with indoor handlers, requiring no ductwork.
