Understanding HVAC Terminology: Your Homeowner's Guide
Your home's heating, ventilation, and air conditioning (HVAC) system is complex, keeping your indoor environment comfortable year-round. Encountering technical terms when discussing maintenance, repairs, or new installations can sometimes feel overwhelming. At Unlimited Heating & Refrigeration Inc, we believe that informed homeowners make the best decisions. This guide is designed to help you understand common HVAC terminology so you can better communicate with technicians, understand your system's needs, and feel confident about your home comfort.
Let's break down some of the terms you might hear:
Air Conditioner (AC): A system or unit that cools air by removing heat and moisture. It's a key part of your Air Conditioning system, especially vital during Moscow, ID summers.
Air Handler: The indoor part of a split system that contains the fan, cooling coil (or evaporator coil), and often the heating coil or electric heating elements. It circulates conditioned air throughout your home via the ductwork.
AFUE (Annual Fuel Utilization Efficiency): A rating that measures how efficiently a furnace converts fuel into heat over an entire heating season. A higher AFUE percentage means the furnace is more efficient, potentially saving you money on Heating Service and energy bills. This is a crucial factor when considering Furnace Replacement.
BTU (British Thermal Unit): A unit of heat measurement. In HVAC, it's often used to describe the heating or cooling capacity of a system. A higher BTU rating means a system can heat or cool a larger space. Correct BTU sizing is essential during AC Installation or Furnace Installation.
Compressor: Often called the "heart" of an AC or heat pump, this component is located in the outdoor unit. It pumps refrigerant, moving heat between the indoor and outdoor units. Issues with the compressor often require AC Repair or Heat Pump Installation.
Condenser Coil: Located in the outdoor unit of an AC or heat pump, this coil releases heat from the refrigerant into the outside air during the cooling process.
Ductwork: The system of channels or tubes (usually made of sheet metal, fiberglass, or flexible material) that distributes heated or cooled air from the HVAC unit throughout your home. Leaks or blockages in ductwork can impact efficiency and Indoor Air Quality.
Evaporator Coil: Located in the indoor unit (air handler) of an AC or heat pump, this coil absorbs heat and moisture from the indoor air as the refrigerant evaporates within it.
Filter (Air Filter): A critical component, usually located near the air handler or return air vent, that captures dust, pollen, pet dander, and other particles from the air before it circulates through your system and home. Regularly changing your filter is a key part of AC Maintenance and Furnace Maintenance and impacts Indoor Air Quality. Filters have MERV ratings (Minimum Efficiency Reporting Value) which indicate their ability to capture smaller particles – a higher MERV rating means better filtration.
Furnace: The indoor unit of a heating system that burns fuel (like natural gas or propane) or uses electric resistance to heat air. This is a core component of your Heating system. Common issues may require Furnace Repair.
Heat Exchanger: Found in a furnace, this component transfers heat generated by burning fuel to the circulating air without mixing the combustion byproducts into the air stream. Cracks in the heat exchanger are serious and can necessitate Furnace Replacement.
Heat Pump: A system that can provide both heating and cooling. It works by transferring heat: from inside to outside for cooling, and from outside to inside for heating. Heat pumps are an energy-efficient option for Heating Replacement or AC Replacement in areas like Moscow.
HSPF (Heating Seasonal Performance Factor): A measure of the efficiency of heat pumps during the heating season. A higher HSPF indicates greater heating efficiency. Important to consider for Heat Pump Installation.
HVAC: Stands for Heating, Ventilation, and Air Conditioning. This is the broad term for the systems that control the climate and air quality in your home. Unlimited Heating & Refrigeration Inc specializes in all aspects of [HVAC]().
Mini-Split System: A type of HVAC system that allows for zoning (controlling temperatures in individual rooms or areas). It consists of an outdoor unit connected to one or more indoor units via a small conduit. Ideal for additions, garages, or rooms without existing ductwork. Learn more about Mini-Split options, including Mini Split AC Installation and Mini Split AC Replacement.
Refrigerant: A substance (like Freon, though newer, environmentally friendlier refrigerants are common now) that circulates through an AC or heat pump system, absorbing and releasing heat to provide cooling or heating. Low refrigerant levels often indicate a leak, requiring professional AC Repair.
SEER (Seasonal Energy Efficiency Ratio): A rating that measures the energy efficiency of air conditioners over a typical cooling season. A higher SEER rating means the unit is more efficient and uses less electricity to cool your home. This is a key consideration for AC Replacement.
Thermostat: Your home's control center for the HVAC system. It allows you to set desired temperatures and often program schedules. Modern thermostats offer advanced features for comfort and energy savings.
Ton: A unit of measurement used to describe the cooling capacity of an air conditioner (one ton equals 12,000 BTU per hour).
Zoning: An HVAC system setup that allows you to control temperatures independently in different areas or "zones" of your home, offering customized comfort and potentially saving energy.
Understanding these basic terms can help you feel more confident when discussing your heating and cooling needs. Whether you're dealing with an unexpected issue, considering a system upgrade, or signing up for a maintenance plan, knowing the language empowers you.
Our friendly, knowledgeable technicians are always happy to explain what's happening with your system in plain language. We're here to ensure your comfort and keep your system running efficiently.

Outstanding customer service!! I was blown away by the help, clear communication, and expertise of this company. My parents were experiencing plumbing problems and Amanda not only took my call after hours but had someone to their house early the next morning and the problem solved in an hour. I would highly recommend this company for any plumbing needs and won’t hesitate to use them again! Very happy with the experience.
Fast scheduling for my new Bosch dishwasher installation. The technician was on time, friendly and very experienced. The whole process was under 2 hours. Great work.
Furnace and AC installation: Exceptional responsiveness, quality professional installation (incl some deduct work revision in attic & coordination with electrician). All personnel were congenial and clearly presented info and answered all questions clearly. While a big job, we hardly knew they were here: quiet, efficient and cleaned up very well daily.Great people, Great service! Absolutely would call them for other service! Highly Recommend!!
