BLOWER MOTOR RELAY

There are two main types of blower motors.
1. Single-speed units operate on an on/off switch. These motors operate at a consistent speed until the desired temperature is achieved.
2. Multi-speed models allow variable fan speeds, which can help alleviate cold spots and make other temperature adjustments. Variable speed motors are also more energy efficient; since they can control small temperature shifts, multi-speed units don’t use as much fuel to heat up larger spaces.
How to Identify a Failing Blower Motor Relay
In a blower motor, the relay supplies the power that allows the fans to circulate warmed air. Essentially an on/off switch, the blower motor relay’s reactions start and end the heating process in HVAC systems by controlling the flow of current between the power source and the motor.
Blower motor relays tend to wear out over time from the stress of constantly flicking back-and-forth.
These signs indicate a possible issue with the blower motor relay.
• When the blower motor does not respond at all, it may not be due to mechanical failure within the motor itself. Since the relay supplies the current that makes the motor move, a nonresponsive motor may be the result of a worn-out relay.
• The blower motor relay does more than channel electrical current. Relays are a vital protection against electrical surges. When the relay receives a jolt of strong current or simply cannot manage and distribute its load, it will send excess current into the fuse. This forces a shutdown which protects the entire system from electrical damage. Thus, blown fuses could be a sign of relay issues.
• Blower motor relays handle a large amount of current. Malfunctioning relays aren’t able to distribute their load properly. This can cause the relay to retain excess heat and become warm to the touch. If left unaddressed, the heat from a compromised relay can melt away the plastic casing and components around it. In extreme cases, the panel or fuse box can sustain damage as well.
A malfunctioning relay means the HVAC system can’t distribute the treated air until the problem is corrected.

BLOWER MOTORS

A blower motor is the component within a home’s HVAC system. The motor blows heated air through vents when the heating system is in use. Conversely, some blower motors blow cold air when the air conditioning system is in use. There are two main types of blower motors: single-speed motors and variable-speed motors.

CAPACITOR

An HVAC capacitor is a device that stores electrical charge and is used in heating, ventilation, and air conditioning units. There are two types of capacitors found in HVAC units: start capacitors and run capacitors. Some HVAC units will only have a run capacitor.

DRAFT INDUCER ASEMBLY

Furnace draft inducer assembly. The draft inducer motor draws air into the burner and exhausts it out the flue. If the draft inducer motor is defective, the furnace may not heat.

ELECTROCSTATIC AIR FILTERS

Your air conditioner gives you cool, clean and fresh indoor air during the hot summer days. Thanks to air filters. Air filters play an integral role in keeping the air in your home clean and healthy. Here are the different types of air filters to choose from.
Fiberglass Air Filters
Disposable, most affordable yet with the lowest straining ability of all the types are fiberglass air filters. They work better in protecting your air conditioning system than screening dust and pollutants in the air. If you are using this type of air filter, you might still be prone to respiratory problems.
Pleated filters
Made of polyester fabrics or cotton folds, pleated air filters are effective in filtering dust and other pollutants. Choose those with more pleats because they offer better filtering performance.
Washable Air Filters
Washable air filters cost bigger than disposable types but save you big time in the long run. They can be removed and cleaned, so you don’t need to constantly replace them. Read the manufacturer’s specs on how to maintain filters of this type. Make sure to schedule cleaning ahead of the time. Let it dry completely because using it dump will cause mold growth and bacteria buildup.
Electrostatic Air Filters
Electrostatic air filters use an electrostatic charge to magnet dust and airborne particles then prevent them from being distributed in your home. Some filters of this type are washable while there are also those that aren’t.
HEPA Filters
High-efficiency particulate air filters are best for people with allergies and prone to respiratory difficulties. They are effective in screening contaminants up to 99.97% — a reason why the US Department of Energy recommends this type.
UV Filters
This type of filter uses ultraviolet lights to kill bacteria and viruses in your home. Although less efficient in screening dust and other pollutants, they are good at combatting microorganisms which are also dangerous to your health.
The variation of air filters provides choices for home and business owners in terms of efficiency, health benefits, costs, and maintenance. Call an HVAC professional at A/C ADVICE OF SOUTH CAROLINA for suggestions as to which type of air filter fits your home and comfort needs.

FLAME SENSOR

Furnace flame sensor. The flame sensor monitors the burner to detect whether or not a flame is present. If the flame sensor is defective, the furnace may not heat.

FURNACE CIRCUIT OR CONTROL BOARD

Furnaces use a circuit or control board to perform any number of activities from simply igniting your furnace to alerting you to problems within your unit. This “brain” within the furnace initiates and ends the heating operation, monitors the temperature and watches your furnace for signs of problems.
Types of Control Boards
For a basic furnace, your control board will drive the operation of your ignitor, gas valve and flame sensor. These “simple ignition controls” are most common on older, less efficient units.
Integrated furnace controls, common on many high-efficiency furnaces today, lead the operation of many more activities. These might include the workings of the furnace blowers, as well as the onboard diagnostic system that provides you with troubleshooting information.
Control Board Operation
Typically, your control board kicks on the furnace ignition system (either a spark generator, glow coil or pilot light) after receiving a single from your thermostat that the temperature is too low. Once your ignitor is running hot, the control board gets gas flowing through the burners where that is ignited to start heating your home. Your control board then oversees the furnace’s operation until it receives another signal from your thermostat that your home has reached the appropriate temperature.

Furnace Heat Exchanger

The heat exchanger in a furnace separates the combustion process from your breathing air. It is a combination metal chamber and passageway that starts at the burner assembly and ends approximately where the chimney vent connects to the furnace. Air is heated as it is blown across the hot metal surface of the heat exchanger. The heated air is then distributed through the house to warm the house.
The heat exchanger must have an air (and gas) tight seal to separate the gasses in the flue products inside the heat exchanger from the breathing air passing over the outside surface. This is because the flue gasses can be poisonous – such as deadly carbon monoxide – and contamination of the breathing air by these gasses pose a health risk and can be fatal
All heat exchangers fail eventually. This is because of metal fatigue. Metal when it is heated up expands, and when it is cooled off contracts. This expansion/contraction cycle is part of the normal furnace heating process. Over time this constant expansion and contraction have the same effect on a heat exchanger that bending a paperclip back and forth: it breaks. And when that happens contamination occurs and it is no longer safe.
While heat exchangers are typically manufactured to last between 10 – 20 years, many factors can accelerate the process of heat exchanger failure. These factors usually fall under the categories of poor maintenance, poor initial system design, and installation, or poor equipment design by the manufacturer. Anyone or a combination of these factors can result in a heat exchanger failing in a few short years.

PRESSURE SWITCHES

A furnace pressure switch is an automatic safety feature located near the motor. It shuts the furnace down if it senses negative pressure created by the draft inducer motor. This protects your home from dangerous backdrafting, which is when exhaust fumes are reintroduced into the system. The pressure switch also guards against gas leaks and prevents the furnace from cycling if there’s a mechanical failure.
Types of Pressure Switches
The design and number of pressure switches your furnace has depends on whether it uses conventional or condensing technology:
A single-stage conventional furnace has one hose leading from the draft inducer fan to the pressure switch.
A single-stage condensing furnace has two hoses on the pressure switch, one to sense pressure at the draft inducer and another for sensing venting pressure at the condensate collector box.
A two-stage furnace may have two pressure switches.
A modulating furnace may have three pressure switches.
