An HVAC system is an installed unit in your home that provides heating, ventilation, and air conditioning. These systems are essential to ensuring your home remains at a comfortable temperature for you and your family all year round, regardless of where you live or what the weather is like outside. Using an innovative thermostat, homeowners can easily monitor and control their home’s indoor temperature with the click of a button. By doing so, your HVAC system will operate according to preset temperatures and schedules, so you do not have to worry about it during the day. 

At the same time, your HVAC system is also in charge of ventilating the air in your home to make sure you and your family do not breathe air contaminated with dust, dirt, hair, and other airborne debris. As a result, you are less likely to experience allergy and cold-like symptoms that can make your indoor environment uncomfortable. 

All in all, the job of our HVAC system is pretty straightforward. However, to work optimally, your HVAC system is made of numerous mechanisms and parts that work together to ensure you can control your home’s temperature quickly. Some of these critical mechanisms include: 

• A heat exchanger
• A blower motor
• Combustion chamber 
• Condenser coils or compressors 
• Evaporator coils 
• Refrigerant 
• Thermostats 
• Ductwork 

Furthermore, there are also different types of HVAC systems that can be categorized as ductless systems, split systems, or hybrid systems. On the other hand, subtypes of HVAC systems include: 

• Furnaces: Furnaces warm and circulate the warmed air across your air duct system that connects to each room of your home. These systems are powered by natural gas, propane, or electricity and generate heat before being transported across a heat exchanger and pushed through your home.  
• Water heaters: Water heaters deliver hot water to your home through water pipes. These heaters can also pump water under your flooring to heat it. 
• Humidifiers: Humidifiers generate a mist in your home to ensure enough moisture is in your air. It prevents your indoor air quality from becoming too dry while ensuring that it doesn’t encourage mold and mildew growth.    
• Heat pumps: Heat pumps use a thermal heat transfer to heat and cool your home throughout the year. It will either pull warm or cooled air from the exterior of your home into the unit before a compressor alters the temperature of the air. 
• Air conditioning: Air conditioners use refrigerant to cool heated air to keep your family cool by pushing chilled air throughout your home during warmer months of the year. 
• UV air purifiers: UV air purification units work to remove airborne bacteria, viruses, and other harmful airborne pollutants using a high-powered UV light. This unit will help prevent you and your family from getting sick. 
• Boilers: A boiler unit uses oil, gas, or electricity to create heat on a coil. The heat is utilized to boil water held within a boiler tank, which then transforms the heated water into steam. This steam is then pushed through your home’s ductwork to heat each room via an air vent.

When purchasing a new HVAC system for your home, homeowners may be surprised to find that there are numerous different styles, sizes, and brands of HVAC units available for them to purchase. For this reason, this process can become quite overwhelming –especially if you do not understand how HVAC systems work and what factors you should be looking for. Every home is different. Therefore, what works for one may not work for another. 

Essentially, the HVAC system you choose for your home will vary depending on the unique factors of your home, which will ultimately allow it to function optimally while remaining energy efficient throughout the year. Therefore, if you are beginning to look for a new HVAC system for your home, there are many factors that will influence your final purchase decision. With that said, here are some of the factors you can expect to consider when choosing your HVAC system for your home: 

• What your budget is for a new HVAC unit. 
• The approximate lifespan of a unit compared to other units available to you that are within your budget. 
• The HVAC unit’s Seasonal Energy Efficiency Ratio (SEER) which will directly influence how energy efficient your home remains throughout the year. 
• The type and size of the HVAC unit that is currently installed in your home and whether you want to remain with the same kind of unit or look for different options. 
• How much noise the HVAC unit makes when it is functioning.  
• The type of maintenance mandatory for your HVAC system to function optimally throughout the years. 
• The number of British Thermal Units (BTUs) the HVAC system uses. This will have a direct influence on the size of the HVAC unit you choose for your home, as each system has a different BTU rating.
