The Basics – Heating Systems and Their Components

  1. Furnace: A furnace is a central heating system that uses natural gas, oil, or electricity to heat the air, which is then blown through the ductwork to distribute heat throughout your home.
  2. Boiler: A boiler is a heating system that uses hot water or steam to circulate heat through radiators or radiant floor systems.
  3. Heat Pump: A heat pump is an energy-efficient heating and cooling system that transfers heat from one space to another. It extracts heat from the outdoor air or ground and transfers it inside during colder months and vice versa during warmer seasons.
  4. Air Handler: The air handler contains the fan and heating or cooling coils within a central heating and cooling system, managing the flow and distribution of conditioned air through the ductwork.
  5. Ductwork: The ductwork refers to an interconnected network of metal or flexible tubes that channel air from the heating or cooling system throughout your home. Properly sealed and insulated ducts are crucial for maintaining energy-efficiency.

Essential Heating Maintenance Terms

  1. Air Filter: Air filters are reusable or replaceable components that help remove airborne particles, including dust and debris, from the air moving through your HVAC system. Regularly changing or cleaning air filters is crucial for maintaining good indoor air quality and system efficiency.
  2. Annual Fuel Utilization Efficiency (AFUE): AFUE is a measure of a furnace or boiler’s energy efficiency, expressed as a percentage. This rating demonstrates the proportion of fuel consumed during heating, with higher percentages indicating greater efficiency. The United States Department of Energy (DOE) requires new furnaces to have a minimum AFUE of 81%.
  3. Combustion Chamber: The combustion chamber is where the fuel (natural gas, oil, or propane) is burned to create heat in furnaces and boilers.
  4. Heat Exchanger: The heat exchanger transfers heat generated in the combustion chamber to the air or water circulating in the heating system without mixing the two substances.
  5. Seasonal Energy Efficiency Ratio (SEER): SEER is a measure of the cooling efficiency of air conditioners and heat pumps and indicates the ratio of cooling output to the energy consumed during a typical cooling season. Higher SEER ratings represent greater energy efficiency.

HVAC Diagnostic Terminology

  1. Airflow: Airflow refers to the movement of air through your HVAC system and ductwork. Inadequate airflow can result in uneven heating or cooling, decreased efficiency, and potential damage to the system’s components.
  2. Delta T: Delta T is the difference in temperature between the air entering and leaving your HVAC system’s indoor unit. Knowing the Delta T can help HVAC technicians evaluate system performance and identify potential issues.
  3. Draft Inducer Motor: The draft inducer motor helps ensure the proper exhaust of flue gases by creating a draft within your heating system, mitigating the chance of carbon monoxide buildup in your home.
  4. Pilot Light/Ignition System: In gas-powered furnaces and boilers, the pilot light or ignition system is responsible for igniting the main burner. Ageing systems might feature a standing pilot light that stays lit continuously, while newer models utilize an electronic ignition system.
  5. Static Pressure: Static pressure refers to the resistance air faces while moving through the HVAC system and ductwork. An accurate understanding of static pressure can help diagnose airflow issues and identify necessary ductwork modifications.

HVAC Ratings and Certifications

  1. ENERGY STAR: ENERGY STAR is a U.S. Environmental Protection Agency (EPA) program that identifies and promotes energy-efficient products, including HVAC systems. Rest assured that any HVAC system featuring the ENERGY STAR label meets or exceeds the standards for energy efficiency.
  2. Heating Seasonal Performance Factor (HSPF): HSPF is a measure of a heat pump’s heating efficiency over an entire heating season. A higher HSPF rating signifies better energy efficiency. The minimum HSPF required by the DOE for split-system heat pumps is 8.8.
  3. North American Technician Excellence (NATE): NATE certifies HVAC professionals, ensuring that they possess the knowledge and expertise to perform efficient installations, maintenance, and repairs for residential and commercial heating and cooling systems.
  4. Manual J (ACCAs Manual J): Manual J is a methodology from the Air Conditioning Contractors of America that ensures professional HVAC technicians accurately measure and size the equipment to meet your home’s specific heating and cooling needs.
