Air conditioner replacement parts and accessories

While air conditioner parts are designed for longevity, they can become damaged or worn and need replacement. Some of the most common parts and accessories you may need for your air conditioner system include:

• Air conditioner drain products: drain lines on your AC unit can be clogged and may need replacement or a drain cleaner.

• Plenums & filter boxes: help to distribute fresh air into your home

• AC Evaporator coils: remove heat from the air through the use of refrigerant

• Condenser coils: hold the refrigerant in their liquid form

• Compressors: circulate the refrigerant through the system\

• Refrigerant: absorbs heat and provides cooled air.

• Expansion valves: remove pressure from the liquid refrigerant so it can turn back from a liquid to a vapor

• Equipment pads: hold 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 that your furnace works properly and efficiently. Some of the most commonly replaced furnace parts include:

• Pilot light: a flame that burns constantly, so it is ready to ignite the gas when the furnace turns on

• Thermocouple: detects if the pilot light is on and will signal the gas valve that it can open

• Hot surface igniter: works in place of the pilot light on newer furnaces

• Flame sensor: a safety device that ensures there is heat from the hot surface igniter, or it will shut the gas off

• Gas valve: adjusts the pressure of the gas coming into the furnace system

• Burners: make a flame by mixing gas and air

• Heat exchanger: holds gases when the fuel is burned and gives off heat to the surrounding air

• Draft inducer motor: pushes the toxic air formed during combustion out of the home

• Pressure switch: makes sure that the draft inducer motor is on; otherwise, it will not allow gas to come into the furnace

• Blower motor: pushes warm air through the duct system

• Capacitor: starts the blower motor and keeps it running

• Vent kits: where toxic gas from the system is removed

• Gas piping: delivers natural gas to the furnace system

• Zoning & dampers: can be added to a system to control where the warm air travels

• Humidifiers: add moisture to the air to reduce dryness in the home

HVAC supply parts replacement parts and accessories

HVAC Equipment utilizes many of the same parts and accessories as air conditioner units and furnaces as they are two primary components of an HVAC system. Additionally, when you have a complete HVAC system, you will have parts such as:

• Thermostats: control the temperature in your home by signaling the heat or cooling system to start

• Air filters: help trap dirt, debris, and allergens so they don't circulate in your home's air. HEPA-type filters can also trap bacteria and viruses.

• Grille covers: cover the HVAC systems return vents

• Air purifiers: trap small particulates and remove them from the air to improve your home's indoor air quality. 

Heat pump repair parts and accessories

Heat pumps will have many of the same components as air conditioning systems and furnaces, such as a compressor, condenser, expansion valve, evaporator coil, blower motors, and an equipment pad. In addition to these parts, they also have:

• Accumulator: stores refrigerant when needed to prevent an imbalance

• Crankcase heater: prevents refrigerant migration and condensation

• Reversing valve: controls the direction of the refrigerants' flow

Mini-split repair parts and accessories

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

• Air handlers: the primary indoor components of the system which deliver cooled or heated air into each room or space

• Copper tubing: carries refrigerant from the outdoor unit to each indoor handler

• Remote: controls each air handler

What are the major components of a heating system pump?

Heat pumps provide both heating and cooling for your home. They consist of three primary components; the condenser, the compressor, and the evaporator. When the heat pump is in heat mode, the refrigerant will be sent through the system to the heat source. At this point, it will remain gas before moving outside, where it turns into liquid again before going through the valve. At this valve, the liquid will change back to gas, and the warmed air will be distributed by your split HVAC system's blower motor and ductwork.

In summer, the system will work in reverse as an air conditioning system, where it removes the warmth from the outside air before transferring it inside.

What are the major components of a furnace?

Multiple components work together to help your furnace produce warm air through your home. These components are responsible for starting the system up, heating the air, and pushing it through the vents in your home.

The thermostat is the start of your furnace's function as it will send a signal to the system that it needs to start when the temperature drops below the set level. The signal is first sent to the gas valve, which will open up to let gas in and control the amount that flows into your furnace.

Now that there is fuel in the system, the burner component will heat up the heat exchanger. The heat will circulate through the exchanger tubes to transfer heat to the air. The blower motor will move the heat through the plenum and then out through the ductwork until your thermostat sends a signal to shut it off.

What are the major components of an air conditioning system?

Four components work together for a central air conditioner system to deliver cooled air into your home. The evaporator coil, located in the air handler, absorbs heat and humidity as the refrigerant passes through it. After the air passes through the evaporator coils, the cool, dry air is fed back through your home's ductwork. Contact Superior Home Supplies today for any of your major HVAC supply part needs.

The compressor also helps during the cooling process. The compressor is located in the outdoor unit, where it compresses the warm vapor from the refrigerant and makes it denser. The refrigerant is then pressurized and pushed through the condenser coil, which releases the heat into the outdoor air. The expansion valve will then turn the liquid refrigerant back into a cold mist to go back to the evaporator coil and start the cooling process again.

Which component can be used for both heating and cooling?

The heat exchanger is responsible for transferring heat, which means it simply moves heat from one place to another. Therefore, it can be used in both heating and cooling. In an air conditioner, it turns heat into cool air, and in a furnace, the exchanger warms the indoor air.

What are the three main parts of the entire HVAC system?

HVAC stands for heating, ventilation, and air conditioning, and those three components are necessary for a complete HVAC system. When the three components are together correctly, you can enjoy an energy-efficiency system that can help keep your home at a comfortable temperature all year round.

The heating component of an HVAC system can consist of a natural gas furnace, boiler, or propane heating system. This system will be connected to the water system, which will also provide your home with hot water.

The ventilation system often involves an air handler and ducts that carry the warmed and cooled air throughout your home.

The cooling component is an air conditioner which will help provide cool air in the summer and reduce humidity in the home.

What does the "SEER" rating stand for?

It is essential to find out the SEER rating of your air conditioning system when making a purchasing decision. SEER stands for Seasonal Energy Efficiency Ratio and is the ratio of the cooling output of your AC unit during the warm season divided by the energy it uses. This can help you determine how efficient your system is compared to other units.

What are the most common HVAC problems?

Staying on top of HVAC problems can mean the difference between a minor repair and a major repair. Watching out for common HVAC problems can also help you ensure that your system is operating at its highest energy efficiency, so you can enjoy lower energy bills. Below are some common problems you may have with your HVAC system.

• Dirty filters: While an AC filter may seem like a simple piece of your system, it plays a vital function. If it is not regularly changed and gets dirty, it can restrict your system's air flow and significantly strain your system.

• Pilot/ignition problems: Dirty pilots, burners, or flame sensors can cause delayed ignition, short-cycling, and heavy wear and tear on the system.

• Thermostat problems: All types of thermostats can suffer from malfunctions. Some can be simple as a battery replacement, while others may have electrical issues. When your thermostat is malfunctioning, it may fail to start your system.

• Worn belts and bearings: Belts and bearings need proper lubrication to stay in good shape. When they become worn or damaged, it can lead to airflow issues or irregular heating.

• Unusual noises: Loud or unusual noises coming from your HVAC system often indicate a problem with your HVAC parts. Squealing can be a sign of bad bearing or a failing motor. Rattling noises can be signs of loose or broken parts or components that should be replaced.

• Dirty coils: Dirt and debris can get into the evaporator or condenser coils and cause them to work harder and less efficiently.

• Blower problems: A constantly running furnace blower, when the thermostat is not set with the fan in the on position, could mean a problem with a stuck relay or a bad circuit board.

• Leaks: High-efficiency furnaces and air conditioners produce condensate, which will need to drain out of the system. You may find water around your system if the drain line is clogged.

What is the difference between an air conditioner and a heat pump?

While an air conditioner and heat pump work similarly when they are cooling a house, only a heat pump can be reversed to heat a home. In the winter, a heat pump will absorb the heat energy from the outside air and transfer it into the house. An air conditioner system will have to be paired with a furnace to have both heating and cooling in your home.

What are the most common types of heating and cooling systems?

While there is a wide range of heating and cooling supply options on the market, there are some more common heating and cooling systems you are most likely to find in homes.

• Split systems: An HVAC split system is one of the most common systems used for heating and cooling. It consists of one system for heating, usually a furnace, and one for cooling, usually an AC unit. One thermostat will control both these systems. The heating system is often located indoors in a basement or utility closet, while the cooling system will be outdoors.

• Packaged systems: Packaged AC systems are less common than split systems, but they are a good option when you have a small space. These systems have heating and cooling components in one cabinet, typically on the roof, in the attic, or outside the home. They will connect to your home's ductwork through a hole in the wall.

• Zoned system: Zoning systems can allow you to control the temperature in different areas of your home by putting in automatic dampers that will enable and restrict airflow to specific areas of the house as needed.

• Ductless mini-splits: Mini-splits are electric systems with an exterior system and one or more indoor handlers connected through copper tubing through the walls. No ductwork is needed, and the system allows you to heat or cool rooms only when needed.
