HVAC (heating, ventilation and air-conditioning) systems provide thermal comfort by supplying clean, fresh, heated or cooled air. They do this by absorbing, transporting and releasing heat, removing humidity, distributing the air throughout the building and controlling ventilation rates.

Air conditioning is a critical part of most people’s homes. It keeps them cool and comfortable throughout the year, especially when it’s hot. It also helps filter out allergens like mold and dander from the air, which can cause asthma or allergies to flare up. However, many people don’t know what HVAC system is right for their home. That’s why it’s important to understand how these systems work, and what their key features are, before making any purchases or hiring an HVAC professional.
There are a number of different HVAC systems available on the market, but they all function slightly differently. Some are all-in-one solutions, while others have a separate component for each task. For example, heat pumps can both heat and cool a space by reversing the refrigerant flow. Furnaces, on the other hand, burn fossil fuels to create thermal energy. This heat is then distributed throughout the house through ductwork, and cooling is achieved by a separate unit, called an air handler.
The best air conditioner for your home will depend on the size of the space, as well as your price range and home comfort preferences. For instance, do you want a system that’s energy efficient, quiet or able to monitor humidity levels? The answers to these questions will help you narrow down your options and find the perfect air conditioning system.
Other factors that might influence your decision include the number of cooling stages the system offers. This refers to the amount of control over the system’s temperature settings, and a higher number usually means more precise and efficient heating.
A good HVAC contractor will also be able to help you decide whether a traditional duct system or a ductless mini-split is right for your home. Ductless systems are more flexible, and can give you pinpointed control over specific spaces in your home, such as your home office or the master bedroom.
Once you’ve selected the right HVAC system, it’s important to keep up with regular maintenance. This will help ensure the system continues to function efficiently and reduce energy costs. A certified HVAC technician will be able to identify any issues with your system, and perform the necessary repairs or replacements.
Heating
The heating component of an HVAC system is responsible for the temperature regulation in buildings and homes. This is accomplished through a heat exchanger, blower fan and ductwork. Its main purpose is to provide a comfortable indoor environment by controlling the temperature, humidity and air quality.
Unlike an air conditioner, which cools the air and pushes it out through vents, a furnace warms and distributes it throughout the house via ductwork. A furnace can be powered by natural gas, oil or electricity. Most modern furnaces have different settings, allowing them to run at full power when needed or at reduced capacity to save energy.
Heating is a vital part of your home’s comfort and can affect the health, well-being and productivity of those living in it. Poorly functioning or outdated systems can lead to uncomfortable rooms, excess humidity and higher energy bills. To ensure that your heating system is functioning properly, it is important to schedule regular maintenance services.
Choosing the right HVAC system for your home depends on a number of factors and preferences. You may want a unit that is energy efficient, quiet or able to monitor and control humidity levels. The best way to find the perfect HVAC system is to consult with a Lennox dealer.
Some people get confused between HVAC and AC units because they both regulate the air inside of a building or home. However, an air conditioning unit only cools the air, while an HVAC system heats the air and pushes it through vents while also ventilating it.
Keeping up with your HVAC maintenance and cleaning can help you avoid the high cost of repairs, energy bills and premature replacement. A professional can perform a variety of tests to determine the condition of your system and recommend any necessary repairs. In addition, a licensed technician can install and replace your furnace and air conditioner. This service is often included in a preventive maintenance agreement. You can also opt to add a programmable thermostat and clean air filters to your system. This will enhance your system’s efficiency and help keep the air in your home healthier and cleaner.
Ventilation
Ventilation is the process of exchanging indoor and outdoor air to remove stale air, control humidity levels, and maintain a comfortable environment. It also helps to reduce the buildup of harmful pollutants and excessive moisture, which can cause damage to building materials and furnishings.
Ventilation systems are typically used in places where people live and work, such as homes, offices, hospitals, schools, factories and public buildings. They can also be found in confined spaces, including mines and containers. These systems bring in outdoor air, filter it and then distribute it throughout the occupied space or area. Ventilation can be accomplished by natural means, such as through open windows and doors or with fans. It can also be done with mechanical systems.
One of the main uses for ventilation is to provide fresh outdoor air to replace stale indoor air, but it can be used in other ways as well. The type of air that is brought in to a space depends on the needs of the occupants and can include both filtered and unfiltered outdoor air.
Another use for ventilation is to control the level of gases and volatile organic compounds in the air. These can be toxic and/or unpleasant to breathe, so filters that remove these substances from the air are often included in ventilation systems. Such filters are usually called gaseous removal, and they can include activated charcoal or permanganate oxidizers. These filters must be regularly replaced or regenerated in order to continue working effectively.
When you consider the amount of time that most people spend in their homes, it’s important to make sure that it is properly ventilated. Poor ventilation can result in a variety of problems, including the accumulation of harmful pollutants and excess moisture, which can lead to mold growth and damage to building materials and furnishings.
Proper ventilation can help to prevent these issues by keeping dust particles from lingering in the air, reducing the amount of cleaning chemicals needed and keeping the humidity levels at an acceptable level. However, it is important to remember that ventilation only works best if paired with other measures, such as keeping known sources of pollution, like secondhand smoke and diesel emissions, out of the home.
Air Filtration
While air filtering may seem like a small detail, it’s a critical part of your HVAC system that’s underrated for its impact on home health. Filters are a first line of defense that prevents expensive contamination buildup in the evaporator coils, heat exchangers and ductwork. It also cuts energy costs by reducing strain on the system, which can lead to premature breakdowns and costly repair bills.
There are many options for filtration, from low cost, general purpose filters to highly efficient MERV-13 or HEPA. Generally, the higher the MERV rating, the more efficient the filter.
The main function of an air filter is to trap dust, fluff and other particulates as they move through the HVAC system. This can include bacteria and viruses that may make people sick, as well as dust mites and pet dander that can trigger allergies. The filtered particles are then either passed back through the ventilation system and into the environment or sent to the recirculation system for another trip through the house.
Depending on the filter’s design, it can use different techniques to capture particulates. Standard home filters are typically made of a woven, pleated cellulose material with a MERV rating between 5 and 8. Some medium-rated filters use static electricity generated by the flow of air through the filter to create an electrical charge that attracts and holds on to the particulates. These are often washable and reusable, but need to be replaced frequently because the electric charge can fade over time.
High-efficiency filters, such as HEPA, use a netting of microscopic fibres to hold onto particulates. They can also incorporate a chemical coating that kills the microbes on contact. For very sensitive environments, such as a lab or art studio, there are specialized filters that can remove gases and volatile organic compounds from ventilation air.
The key to proper filtration is the right selection and installation, along with following maintenance guidelines. Filters must be the right size for your HVAC system so they don’t cause too much resistance, and they must be properly installed in the filter slot to prevent air bypass around them. A pressure gauge should be provided on the filter holder to indicate when the resistance becomes excessive, which is usually when the filter needs to be changed.
