At James River Air Conditioning, we now HVAC terms can sometimes sound like a different language. Whether you’re discussing a new system installation, understanding your repair options, or just curious about how everything works, it helps to be familiar with the lingo.
That’s why we’ve created this HVAC Glossary of Terms — a simple guide designed to help you better understand the heating, cooling, and air quality systems that keep your home comfortable year-round.Â
From AFUE to Zoning, this glossary covers the essential terms our team uses every day.Â
AFUE (Annual Fuel Utilization Efficiency)
AFUE measures how efficiently your furnace converts fuel into heating energy. The higher the percentage
Airflow
The movement or distribution of air within the duct system. Proper airflow is essential for even cooling and heating throughout the home.
BTU (British Thermal Unit)
A unit of heat. One BTU is the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit. The highest the BTU rating, the greater the heating or cooling capacity of your system.
BTUH (British Thermal Units per Hour)
The measurement of heat energy a system can produce or absorb in one hour.
Carbon Monoxide
A colorless, odorless, and toxic gas produced by burning fuel. It’s crucial to ensure your heating systems are properly maintained to avoid leaks.
Central Air Conditioning System
A system that cools air at a central location and distributes it throughout the home using ducts and fans.
Damper
A movable plate within ductwork that helps regulate airflow. It’s used in zoning systems to direct air to the areas that need it the most.
Energy Star®
An EPA (Environmental Protection Agency) certification that indicates a product meets strict energy efficiency guidelines, helping you save on energy costs.
Evaporator Coil
Part of your air conditioning system, this coil absorbs heat from the air inside your home. It is typically located inside the air handler or attached to your furnace.
Heat Pump
An HVAC system that heats and cools by moving heat between your home and the outside air. In the winter, it draws heat from outside and pumps it indoors. In the summer, it reverses the process, removing heat from your home.
HSPF (Heating Seasonal Performance Factor)
A rating that measures the efficiency of a heat pump during heating mode. The higher the number, the more efficient the system.
Indoor Coil
The component within your air handler or furnace that absorbs heat from the indoor air, helping to cool or heat the home as needed.
MERV Rating
The MERV (Minimum Efficiency Reporting Value) rating of a filter describes the size of the holes in the filter that allow air to pass through. The higher the MERV rating, the smaller the holes in the filter, the higher the efficiency.
Outdoor Coil
Part of your air conditioning or heat pump system that either releases or collects heat, depending on whether you’re heating or cooling your home.
Odors/Chemicals
Airborne contaminants in the form of gases that can affect your indoor air quality.
Programmable Thermostat
A thermostat that allows you to set different temperatures based on the time of day. This helps reduce energy consumption and maintain comfort.
R-410A Refrigerant
R-410A is a high-efficiency, chlorine-free refrigerant commonly used in residential and commercial air conditioning systems. It replaced older refrigerants like R-22 due to it’s ozone-friendly properties. However, R-410A has high Global Warming Potential (GWP) and is currently being phased out in favor of lower-GWP alternatives like R-32 and R454B, in alignment with new environmental regulations.Â
R-32 Refrigerant
R-32 is a next-generation refrigerant used in air conditioning systems. It has a lower Global Warming Potential (GWP) than older refrigerants like R-410A and offers better energy efficiency.Â
R-454B RefrigerantÂ
R-454B is an environmentally friendly refrigerant designed to replace R-410A in residential and commercial HVAC systems. It has a significantly lower GWP and similar performance, making it a key player in the industry’s move towards more sustainable solutions.Â

SEER (Seasonal Energy Efficiency Ratio)
A measure of the cooling efficiency of air conditioners. The higher the SEER rating, the more energy-efficient the unit, meaning lower energy bills and better environmental performance.Â
Thermostat
A device that controls the temperature of your home’s HVAC system, allowing you to adjust settings for comfort and energy savings.
Variable Speed Motor
A motor that adjust its speed to match the heating or cooling needs of your home, offering enhanced comfort and efficiency.Â
Zoning
A system that divides your home into separate areas or “zones,” each with its own temperature control. This system improves comfort and energy efficiency by directing airflow where it’s needed most.Â

We have some exiting news for those who may not be aware of a unique benefit related to air conditioning—reimbursements through your Health Savings Account (HSA). Yep, you heard that right! In some circumstances, you may be eligible for this reimbursement by leveraging a Letter of Medical Necessity (LMN). Continue reading to discover how your air conditioning expenses may qualify for this unexpected advantage.
According to Treasury Regulation ‘1.213-1(e)(1)(iii), Private Letter Ruling 8009080, air conditioning reimbursement can be possible with a Health Savings Account (HAS), Flexible Spending Account (FSA), or Health Reimbursement Arrangement (HRA), given the submission of a Letter of Medical Necessity. It is crucial to note that reimbursement is not applicable for limited-purpose flexible spending accounts (LPFSA) or dependent care flexible spending accounts (DCFSA). The key is understanding when air conditioning becomes more than a cooling solution – it becomes a medical necessity.
To quality for reimbursement, the primary purpose of your air conditioner must be to treat or alleviate a medical condition. A Letter of Medical Necessity is required to show that the expense is primarily used for medical care. For more personalized information, we recommend speaking with your FSA, HAS, or HRA benefits administrator.

If you’re wondering how you can show your home comfort system love on this Valentine’s Day, here are my top 5 tips. A happy home comfort system = a happy and comfortable homeowner.
Nobody wants to breathe dirty, dusty air. Not even me! It makes it harder for me to pump air. Not to mention the air I'm putting out is dirty!
One of the hardest things for me to do is work efficiently while being covered in grime, dust, leaves, etc. Sometimes critters can create habitats in my area. Gross! Build up around my unit can create less airflow which makes it harder for me to work! Though you and I both don’t like it, I have to use more electricity to be efficient which raises your electricity bill! Sorry I know we both don’t want this, so it’s a good idea to check outside of my unit to make sure everything is clean and running smoothly.
Before we all start suffering from allergies, install an air purification system. With this installed, I can help get rid of any allergens, germs or mold that is in the air.
An easy way to show me love today is by keeping the vents open your house. Even in unused rooms! When you close your vents, it’s messed with my balance and pressure. It’s making it harder for me to heat your home.

Do you notice any of the following unusual sights or smells emanating from your home’s crawl space? (i.e. the narrow, unfinished area that resides under the base of your house)
If you notice any of the above unusual sights or smells, these are all warning signs your crawl space may be compromised.Â
________________________________________________________________________________________________________________________
As we head into the damp spring season, and as more homes change hands in a fast-moving housing market, James River Air Conditioning, has advice on how to secure your crawl space – whether you’ve been in your home for years, or you have a new-to-you home. Many homeowners likely never think about the crawl space, but it can be a major contributor to poor air quality and overall home energy efficiency. Nearly 50% of the air you breathe in your home originates from your crawl space.Â
The crawl space is the home’s foundation. It’s where electrical conduit, water lines, and other utilities are housed. Traditional crawl spaces are a leading source of high humidity, and thus, mold, and microbiological growth, which causes poor air quality and can be linked to asthma, allergies, and other health issues. On the energy side, homeowners can reduce energy bills by up to 15% by controlling air leakage in crawl spaces, allowing HVAC systems and ducts to perform more efficiency.

James River Air’s 5 LOW- or NO-COST Things You Can Do Now To Increase HVAC Efficiency And Save Money Later.
More Than Half of Household Energy Use Comes from Heating and Cooling.Â
Around this time of year, many of us take a look at our energy bill and ask: Why is it SO high? What can I do to lower my bill and improve home energy efficiency without sacrificing comfort?
Per the U.S. Energy Information Administration’s Winter Fuels Outlook 2021 report, U.S. households that primarily heat with electricity can expect to spend 6% more than they spent last winter, on average.
