What Does HVAC Stand For?


Heating, ventilation, and air conditioning--otherwise known as HVAC to many people in the residential and commercial Real estate industry--refers to the systems that regulate airflow throughout a building. By bringing in fresh air and using a mechanical ventilation system, these systems can heat or cool indoor spaces to maintain the desired temperature. There may be various types of HVAC systems available on the market today, but they all operate under this same basic premise.


HVAC units provide many benefits, such as controlling humidity and improving air quality. These units come with air cleaners that can remove bacteria, spores, and virus-sized particles from the air. If you're interested in determining which system is best for your home, an HVAC technician will visit your house for a pre-installation evaluation.



How Does an HVAC System Work?


HVAC systems move air to heat or cool an indoor space. Typically, these systems have three parts: a heating unit, a cooling unit, and ductwork. Bright Hub Engineering says that HVAC systems usually start with ventilation, which draws fresh air. Natural ventilation pulls in outdoor air through windows, doors, or cracks and then relies on pressure differences to push the air throughout a building. However, tight seals on today's homes and offices require fans, blowers, or other mechanical means to circulate air.



Heating Air Conditioning Systems


Most homes and buildings maintain comfortable indoor temperatures using heating and air conditioning systems that work in tandem. These systems usually rely on a forced-air delivery system, which uses ducts to spread conditioned air around the building.


The standard heating process usually starts with a furnace. This uses fuel sources like natural gas, oil, or electricity to create heat. The heat is then sent through the building using a blower or fan.


The heating air conditioning process works by removing heat and humidity from the air, which is then circulated throughout the building using a fan. This is usually done by using a refrigerant to cool the air.

Heat Pumps Belling Wa

Heat Pumps Bellingham Wa


A heat pump cools your home in the same way a central air conditioner does by taking advantage of the fact that heat flows from warmer to cooler temperatures. In order to expel hot air from your building and produce cool air, a heat pump flips this process around so that it draws cold outside air over the even harder refrigerant. The desired temperature is reached and blown into your home by heating up the coils with this process.

Furnaces Bellingham Wa


An HVAC system runs a gas furnace by pulling air into the ducts and forcing it into the furnace. The combustion chamber heats up to the designed temperature while the furnace runs. Then, the air is pushed through a heat exchanger, which becomes heated before being blown by a motor back through the ducts and into your home. We offer furnace repair, replacement, and installation services.

Types of HVAC Systems


An HVAC system's form varies depending on a combination of factors, including the climate where the home is located, how old the house is, and its existing ductwork. Other considerations are the heating and cooling needs of the home. With so many potential variations, your best bet is to consult with an HVAC technician who can help you figure out which option will work best for you.



HVAC systems are not one size fits all - each is individually customized to the home it will be installed in, considering various conditions such as climate, ductwork, as well as other heating and air conditioning needs.

By installing an air purifier, humidifier, or dehumidifier in your home, you can improve indoor air quality while also saving money on energy costs by using a standard or smart thermostat. A Wi-Fi-enabled smart thermostat is especially beneficial because it allows you to make hourly adjustments that conserve energy.



Split System


A split system, also called a forced-air system, has one unit inside and another outside. The configuration you'll need will depend on where you live and the climate there. For example, it's best to have a furnace and heat pump setup if you live in an area that has a really cold climate.


Hybrid Heat Pump


Did you know that, in some cases, it's cheaper to heat your home with a hybrid system than just a furnace? A dual-fuel or 'hybrid' system includes an electric heat pump that works with a furnace. In colder weather, the furnace does most of the work, but in milder temperatures like spring and fall, the heat pump can take over and use less energy.


Packaged System


A packaged system contains the same components as a split system, but all units are stored externally. This is the best option if you don't have space for a heating unit inside your home or want a quieter solution. Additionally, installation costs are lower because there's only one unit rather than multiple units.


A good HVAC system doesn't just regulate the temperature--it can also improve the air quality in your home. Ventilation systems help get rid of stuffy air, while humidifiers and dehumidifiers ensure there's neither too much nor too little moisture in the air. Air purifiers remove spores, bacteria, viruses, and other tiny particles from circulating through your home. Talk to an HVAC professional to see which add-ons suit you and your family.



Ductless Mini-Split

Ductless Mini-Split


According to the Air Conditioning, Heating & Refrigeration Institute, a ductless mini-split system has an outdoor unit that contains the compressor and condenser. Additionally, an indoor air handler mounted in the room blows cooled air directly into said room. This type of ductless system is well suited for just about any space like garages or workshops that don't require a traditional split system; they are also meant for whole-house applications, they are very versatile.


Ducted Mini-Split


A ducted mini-split system uses small tubes to relay air from an outdoor compressor and condenser into a room, which is preferable for homes that don't have much space for regular ductwork. Ducted mini-splits also provide better circulation than ductless systems.

  • Why is new HVAC so expensive?

    New HVAC systems are expensive due to several factors:


    Complexity and Technology: Modern HVAC systems are designed with advanced technology to improve efficiency, reduce energy consumption, and provide better indoor air quality. This technology comes at a cost.


    Materials: High-quality HVAC systems are made with durable materials that can withstand the elements and last for years.


    Labor: Installing an HVAC system requires skilled technicians who have undergone extensive training. Their expertise ensures the system is installed correctly, which is crucial for its performance and longevity.


    Regulations and Standards: Over the years, energy efficiency standards have become stricter. To meet these standards, manufacturers invest in research and development, which can increase costs.


    Warranty: Many HVAC systems come with extended warranties, which can add to the initial cost but provide peace of mind for homeowners.

  • Why are HVAC repairs so expensive?

      HVAC repairs can be costly due to:


    Specialized Skills: HVAC technicians undergo rigorous training and certification processes. Their specialized skills come at a premium.


    Parts and Equipment: Some HVAC parts can be expensive, especially if they are brand-specific or for a high-efficiency unit.


    Urgency: Emergency repairs, especially those outside of regular business hours, can come with added costs.


    Diagnostic Tools: Technicians use advanced diagnostic tools to identify issues, and the cost of these tools is factored into repair prices.

  • What is the best time of year to buy a new HVAC system?

    The best time of year to buy a new HVAC system is typically during the off-seasons—spring and fall. During these times:


    Demand is Lower: Since it's neither too hot nor too cold, there's less demand, which can lead to better deals and promotions.


    Scheduling is Easier: With fewer emergency calls, HVAC companies might have more flexible scheduling options.


    Preparation: Buying in the off-season allows homeowners to be prepared for the extreme temperatures of summer or winter.
