A Quick Guide to HVAC (Heating, Ventilation, and Air Conditioning)

What Does HVAC Stand For?

  • Heating 
  • Ventilation
  • Air 
  • Conditioning

HVAC is an abbreviation for heating, ventilation, and air conditioning. Heating and air conditioning refer to the temperature control of indoor spaces, and ventilation refers to the circulation of air through the home and indoor air quality. 

The HVAC industry has worked diligently to develop the efficient HVAC units found in modern homes. Heating, cooling, and ventilation are important parts of maintaining a healthy and comfortable home. In this blog post, HVAC experts share the basics that homeowners should know about heating, ventilation, and air conditioning units. 

How Does an HVAC System Work?

Homeowners should have a basic overview of how their HVAC system works. Most modern homes use a central air system, which distributes air to each room in the house through ductwork. HVAC systems include furnaces for heating and air conditioners for cooling the home. 

Modern home furnaces burn oil, gas, or propane to produce heat. Some heating systems use electricity or geothermal transfer to heat the home. Heat pump systems are extremely efficient for homes in moderate climates.

Ventilation is the part of the HVAC system that pushes the air throughout the home. The ventilation system includes components such as fans, vents, air filters, and ductwork. Ventilation is important for maintaining healthy indoor air quality and distributing air. 

Important Parts of the HVAC Systemcoil

  • Thermostat
  • Ductwork
  • Evaporator coil
  • Heat pump 
  • Furnace 
  • Air Filters

The thermostat controls the overall function of the HVAC system by turning on the heating or cooling to maintain the desired temperature. The furnace and air conditioner connect to ductwork that distributes the air through vents at the thermostat’s command. 

Most homes have both an indoor and outdoor component to their HVAC system. Air conditioners use evaporator coils containing refrigerant to cool the air, and then the heat and moisture are released via the outdoor unit. 

The ventilation of the HVAC system would not be complete without an air filter. An air filter is a mesh screen placed over the HVAC unit’s air intake to keep debris such as dust, dirt, and pet hair from getting sucked into the unit. Air filters are essential for protecting the indoor air quality inside the home. They should be replaced around every three months or more frequently, depending on the filter type or if allergy sufferers live in the house. 


What Is HVAC Maintenance?

One of the best things homeowners can do for their HVAC systems is schedule routine HVAC maintenance with a qualified expert. Homeowners should always have a trusted local HVAC company a phone call away in case of an HVAC emergency. 

HVAC maintenance appointments include cleaning the air conditioning coils, changing the air filters, cleaning the inside of the unit, and checking for broken parts. During maintenance appointments, the technician will have a chance to fix small problems early before they get out of hand. 

Most HVAC maintenance should be left up to a qualified HVAC technician, but homeowners can change their air filters themselves. Changing an air filter at homet can take less than ten minutes. Changing the air filter on time can improve the performance and longevity of the HVAC system.

Complete Guide to Improving Indoor Air Quality

Three Tips to Help You Breathe Easier This Spring

Spring is finally here, and along with warmer weather comes the influx of seasonal allergies from flowers and tree pollen. Spring cleaning can include the air too. The air we breathe is full of invisible floating particles of dust, dander, pollen, and other allergens. It can be hard to control the outdoor climate, but homeowners can take steps to improve air quality and breathe easier indoors. These three tips for improving indoor air quality can help homeowners achieve cleaner air and help prevent symptoms of seasonal allergies. 

Get More House Plantsplants

Studies have shown that having a multitude of houseplants indoors can help purify the air. Plants create energy through photosynthesis, drawing carbon dioxide from the air and turning it into oxygen. Humans exhale carbon dioxide and inhale oxygen, so having plants around is great for easier breathing. 

Having just one plant in the house does not make a difference in air quality, but having many houseplants will make an impact. Plants work as natural air purifiers, which is the perfect excuse to head to the store and invest in plants this spring. 





Air Purifiers and Air Filters

Houseplants can help a little bit to keep the air clean, but for homeowners who are looking for more effective solutions to improve indoor air quality, an air purifier or air scrubber may be the best option. Air purifiers circulate the air through a filtration system that filters out contaminants and particles in the air. Some air scrubbers use UV light to kill viruses and bacteria that could be airborne. 

All HVAC systems use air filters to remove contaminants such as dust, hair, and dirt from the air before it gets sucked into the system’s air intake. Some air filters are better than others at cleaning the air. The smaller particles are often the most dangerous, but many air filters only filter out larger airborne particles. Investing in high-quality air filters for the air conditioning unit and changing them out often will help to keep the air cleaner indoors. 

AC Maintenance Is Important 

It is recommended to service the home air conditioning unit bi-annually to keep the system working at optimal efficiency. During the AC maintenance appointment, the technician will clean out the inside of the unit and remove any contaminants like dust or grime that may be impacting air quality. 

When the AC unit does its job properly, it distributes clean, cool air around the house. Doing AC maintenance helps to keep the unit working smoothly, keeps utility bills low, and improves indoor air quality. A dirty or malfunctioning air conditioning unit negatively impacts air quality.
