HVAC is a term that is commonly used by everybody, most of them have a general picture of what the term is referring to. However, what does it actually mean? Moreover, how does an HVAC system apply to your home? Other than our wonderful services of HVAC solutions, we can help you break down the term and know more about it.

1. Brief information about HVAC system

Firstly, the word HVAC stands for heating, ventilation, and air conditioning. The system is responsible for heating and cooling residential and commercial buildings. In other words, HVAC will help you control the building’s temperature and refill oxygen. It also has a ventilating source which allows moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide, and other gasses to escape. Keeping your house and office with fresh air and comfort. HVAC can easily be found from single-family homes, offices, schools, to even aircraft and submarines. The system is getting more popular among new constructions.

What is an HVAC system

A lot will wonder what differentiate between HVAC systems and Air Conditioning. Although the two terms are often used interchangeably. HVAC and AC are actually two different terms. While AC is just a system that controls the air inside your building to keep it cool, the HVAC system does more than that. It consists of many parts that work together to not only regulate the temperature but also ventilation. The system can include a furnace, ductwork, air cleaner, smart thermostat, and even air conditioner as well. Expressly, most air conditioners may be subsumed under HVAC systems, but not all HVAC systems have an air conditioner.

2. Type of HVAC System

Now the definition of HVAC is cleared. Nevertheless, how many types of HVAC systems are there? There are a number of HVAC systems, each system changes depending on a home’s heating and cooling requirements, location, age, existing ductwork, and many other considerations. As a result, an HVAC can come in a variety of shapes and sizes. HVAC technician will assist you in determining which of the options below best matches your requirements.

2.1 Split System

Often known as a forced-air system, an HVAC split system includes one unit inside the residence and one outside. A furnace and air conditioner, an air handler and heat pump, or a furnace and heat pump can all be used in this configuration. Which layout is optimal for your home is primarily determined by your location. In really cold climates, for example, the furnace and heat pump combination works best.

2.2 Hybrid Heat Pump

The central heating system in this scenario contains an electric heat pump that works in tandem with a furnace. The heat pump heats the house during the warmer months of the year, such as spring and fall. When the weather is too cold for a heat pump to function properly, the furnace takes over. This HVAC hybrid system, also known as a dual-fuel system, saves money by using a heat pump instead of a furnace to heat your home.

2.3 Ductless Mini-Split

According to the Air Conditioning, Heating & Refrigeration Institute, an HVAC ductless mini-split system has an exterior unit with the compressor and condenser and an indoor air handler positioned in the room that blows the cooled air directly into the room. This type of ductless system is ideal for compact rooms without the need for a standard split system, such as garages and workshops. They aren’t suitable for usage throughout the house. These systems are typically simple enough for homeowners to install themselves.

2.4 Ducted Mini-Split

To transfer air into a room from an external compressor and condenser, a ducted mini-split system employs tubes rather than bigger ducts. This method is ideal for homes with limited space for standard ductwork. HVAC ducted mini-split systems have the advantage of improved air circulation over ductless mini-split systems.

2.5 Packaged System

The traditional components of a split system are included in an HVAC packaged system. All of the units, however, are located outside. This approach is suitable for households that don’t have enough space inside for a heating unit. Even if you have the space for a split system, a packaged system may be preferable because it is quieter (everything is located outside the home) and requires less installation (there is only one unit to install).

3. Where to install HVAC System

After picking up the most suitable HVAC system for your building. Installing is another conundrum. Let’s look into the tips for an HVAC installation that maximize its value. 

3.1 Install outdoor HVAC unit

The outdoor HVAC unit includes the condenser coil and compressor pump. Its primary function is to draw in fresh air from outside and bring it into the house. When determining where to put your outside HVAC unit, there are several factors to consider, including the amount of sunlight, flora, and more.

3.2 Shady Space

Keeping your air conditioner in the shade will help it stay cool. The HVAC unit does not have to work as hard to lower the temperature of the air when the air surrounding it is colder and clean of debris which will extend its life and save you money.

During the hottest portion of the day, look for spots that are shaded by trees or roofing. Consider putting an awning on the side of your house or growing trees if you don’t have any trees or brush to give shade. Try the north side of the house, this will most likely be the spot with the least amount of sunlight.

Not Visible

The HVAC unit is quite big in all considerations. So make sure to find a place that is well hidden to avoid injuries while having some quality time outdoors, and keep your building visually appealing.

3.3 Install outdoor HVAC unit

The blower and evaporator coils are located in the indoor unit. Its main function is to cool air coming in from the outside, remove any moisture, and distribute the cooled air throughout the house. Location, temperature, and safety are all key factors to consider when determining where to put the indoor unit.

3.4 Center of Home

If at all possible, install the indoor unit in the heart of your home. This reduces the amount of ducting required, as well as the amount of labor required of your unit. As a result, you’ll save money on your energy bill and repairs will be easier and cheaper. Utility closets and pantries are two excellent places that are typically close to the home’s center. 

Unlike the outdoor unit, an HVAC indoor unit will be more beneficial if installed as visible as possible. Maintenance, repairs and changing filters will be easily accessed.

Placing an HVAC unit in the attic or garage makes it work harder. Because those areas can get very hot, your HVAC system will have to work extra hard to stay  cool, increasing your bill.
