Compressor

Your HVAC system’s compressor is one of the most important components and without it, you won’t be enjoying cold or warm air during different times of year. The compressor pumps the unit’s refrigerant gas to a high pressure and temperature and uses the condensing coil, expansion valve, and evaporator coil to adjust air temperatures.

Composite Fan Blades

Composite fan blades are extremely reliable for starting and keeping your HVAC running. Fan blades are angled at specific degrees to improve how the air conditioning and heat pump units operate. Composite fan blades can running longer and more efficiently than standard HVAC fan blades, but at a higher cost to replace. [the_ad id=”4195″]

Combined Annual Efficiency (CAE)

Have you heard the term ‘combined annual efficiency’ but are unsure what exactly it’s in reference to? If so, CAE is a measurement of the amount of heat produced in regards to each dollar spent on fuel that is used to heat the air and water. CAE takes AFUE into consideration, which the federal minimum is 80 percent. [the_ad id=”4195″]

Central Air Conditioning

Central air is one of several popular types of air conditioning for your home. These types of systems move cold air through the supply and return vents. As the cold air is pushed throughout the house, it gets warmer and by sending it back to the air conditioner it can continuously be cooled.

Carbon Monoxide (CO)

Carbon monoxide is a colorless, tasteless, odorless gas that forms when fuels incompletely combust. Fuels include natural gas, diesel, wood, gas, and coal to name a few. A home’s heating system can represent as much as five percent of potential sources. CO can become deadly if exposed to it for extended periods of time. [the_ad id=”4195″]

British Thermal Unit (BTU)

You’ve probably heard the term ‘BTU’ in the past but have you ever wondered what the acronym stands for? If so, it’s British thermal unit. This measurement is in reference to the amount of heat that’s needed to raise one pound of water at maximum density through one degree (Fahrenheit). [the_ad id=”4195″]

Blower Wheel

The blower wheel is a component of the blower motor and its job is to move large volumes of air through the duct system. If the blower wheel get dirt or grease built up, it can slow down the wheels rotation and reduce the amount of air your blower motor is capable of moving through your home.

Blower Motor

Your HVAC unit’s blower motor is a key component of the system as a whole. The blower motor is designed to blow hot air through the air ducts during winter and cold air during summer. The two main types of blower motors are (i) single-speed – blows air throughout the house at one speed and (ii) variable-speed – blows air

Annualized Fuel Utilization Efficiency (AFUE)

The thermal efficiency measurement of combustion equipment, such as your furnace or water heater, is referred to as annual fuel utilization efficiency (AFUE). Pronounced ‘A’-‘Few’ is different than the true thermal efficiency as it is a measurement of season-long, average efficiency as opposed to a steady-state, peak measurement. [the_ad id=”4195″]

Air Handler

An air handler, sometimes called an air handling unit (AHU), is the part of your HVAC system that both regulates and circulates air throughout your ductwork. The air handler is your HVAC unit’s large metal box and it contains heating and cooling elements, the blower, filter racks, and dampers. [the_ad id=”4195″]
