Living in Washington or Montana State means you’re no stranger to hot summers and the need for a good AC unit. But have you ever wondered what sets an AC apart from an HVAC system? These terms are often used interchangeably, but they’re not the same thing.
In places like Washington state, full HVAC systems are common because the weather fluctuates a lot between warm and cold. But what is better for the region, an HVAC or just AC? In this post, we`ll take a closer look at it.
So, What Exactly Is an AC Unit?
An AC unit, short for air conditioner, cools down and removes humidity from the air in your home. It works by pulling in warm air, cooling it with a refrigerant system, and pushing the cooler air back inside while sending the heat outdoors.
Here’s how it works, in simple terms:
- Compressor: squeezes the refrigerant gas
- Condenser: gets rid of heat and turns gas into liquid
- Evaporator: soaks up heat from the indoor air
- Expansion valve: keeps the temperature just right
AC units come in different shapes and sizes. The most common types are:
- Window units: These are great for cooling a single room. They’re affordable and easy to install, but not the most efficient.
- Central AC systems: These cool the entire home through ductwork. They cost more upfront and need professional installation, but they’re more efficient and long-lasting.
If you’re in Washington, having a central AC system isn’t just about staying cool. It also helps filter out dust, allergens, and pollutants to keep your air clean. When shopping for a unit, think about how much space you want to cool, what type of system fits your needs, and how much installation will cost. If you’re unsure, CasPro is always here to help.
What Does an HVAC System Do?
An HVAC system goes a step further. It stands for Heating, Ventilation, and Air Conditioning, and keeps your home comfortable no matter the season.
It includes:
- Furnace: heats the air using gas, oil, or electricity
- Air conditioner: cools the air (same as a regular AC unit)
- Heat pump: handles both heating and cooling
- Evaporator coil and blower fan: help move air through your home
- Ductwork: delivers warm or cool air to each room
Heat pumps are great for mild climates and can be more energy-efficient since they handle both heating and cooling. The whole system works together to manage temperature, air quality, and humidity inside your home.
Just like any major home system, HVAC units need regular maintenance. It’s a good idea to have a professional technician check things out now and then to make sure everything is running smoothly. If you’re thinking about installing or upgrading your HVAC system, CasPro can walk you through the process and answer any questions.
HVAC or AC: What’s the Difference?
To make things easier, here’s a quick side-by-side comparison of the two systems:
| Feature | AC System | HVAC System |
| Full Name | Air Conditioning | Heating, Ventilation, and Air Conditioning |
| Purpose | Cools and dehumidifies | Heats, cools, and controls air flow |
| Ideal For | Warm or hot climates | All-season climate control |
| Key Components | Compressor, condenser, evaporator | Furnace, AC, heat pump, ductwork |
| Energy Efficiency | Efficient for cooling only | Can save energy year-round with heat pump |
| Installation Cost | Lower upfront cost | Higher initial cost, more long-term value |
| Common in WA? | Yes | Yes, often includes heat kits |
