When you work in a certain career, you pick up colloquialisms that make sense to the people you work with, but not with your friends at home. What makes sense to heating and air conditioning technicians might go over your head. At Bigham’s One Hour Heating & Air Conditioning, we understand that you want to know what our technicians fixed and what you can do if this problem arises again, but you might not have understood why they performed the repairs they did. That’s why we’ve created an HVAC Glossary of Terms to help you make sense of your repairs.

Trust Bigham’s One Hour Heating & Air Conditioning to fix your HVAC system when you need it the most. It’s always good to know how these systems work so you can diagnose and describe your problems to a professional technician.

Understanding Heat Pumps

This part of our HVAC Glossary Of Terms pertains to your heat pump and the different types of heat pumps that are available. Different heat pumps use different sources of energy to heat your home.

  • Heat Pump functions as both a heating and cooling system. Heat pumps are popular in moderate climates that are found in California.
  • Air-Source Heat Pump – transfers air between your house and the outdoors. It’s powered by electricity.
  • Geothermal Heat Pump – transfers heat between your house and the ground or a nearby water source.
  • Absorption Heat Pump – works like an air-source pump, but is powered by natural gas, propane, solar-heated water, or geothermal-heated water

Understanding Common HVAC Parts

HVAC parts and equipment do tend to break down over time. If you have regular maintenance performed on your system, it will last longer and fewer parts will need to be replaced. This section will help you understand what your technician replaced and why.

  • Air Handler – a unit that has a variable-speed fan, built-in evaporator coil, and electrical controls. The air handler is the indoor component of your air conditioning system. It consists of an air filter, coil, and blower, and its job is to circulate air throughout your home.
  • Evaporator Coil – is a device that cools the refrigerant so it can absorb the heat.
  • Refrigerant – a substance that produces a refrigerating effect while expanding or vaporizing. As the refrigerant cycles through your AC system, it changes from a liquid to a gas, while absorbing and releasing heat throughout the process.
  • Check Valve – a valve designed to permit flow in one direction only.
  • HVAC Air Filter – a replaceable unit that traps dust, impurities, and allergens to improve indoor air quality. You should replace your filter every 90 days on average.

Understanding Air Conditioner Parts

This portion of the HVAC Glossary of Terms applies to your air conditioner, which is a part of your HVAC system. Even if you don’t have central air, your HVAC system relies on a source of outside air. For many people, this outside source comes from the air conditioner.

  • Air Conditioner Monitors and regulates air through a thermostat. Air Conditioners cool your home by drawing heat out of the house and transferring it to the outdoors. The system replaces the hot air with cooler air.
  • Condenser – Facilitates heat transfer.
  • Expansion Valve – Regulates refrigerant flow into the evaporator.
  • Compressor – The part of a refrigeration system where the compression and condensation of refrigerant is accomplished.
