HVAC stands for Heating, Ventilation, and Air Conditioning. It is a technology that provides thermal comfort and acceptable indoor air quality through a combination of processes, including heating, cooling, and the removal of moisture, smoke, odors, heat, dust, airborne bacteria, carbon dioxide, and other gases, as well as temperature control and oxygen replenishment.

It is recommended to replace or clean your Heating and Cooling filter every 30 to 90 days for standard fiberglass filters. However, more advanced filters, like HEPA filters, can last up to 6 to 12 months before needing replacement. The exact timeframe can vary based on factors like pet ownership, allergies among residents, and the specific manufacturer’s recommendation. This can help avoid the need for more expensive HVAC repair services in the future. 

The size of the Heating and Air Conditioning system you need depends on several factors, including the square footage of your home, the climate zone you live in, the age and construction of your home, the ceiling height, and the quality of insulation. Heating and Air professionals typically use the Manual J calculation to determine the best size for your specific needs.

It is advisable to have your HVAC system serviced at least once a year to ensure it operates efficiently. Typically, it’s best to service the air conditioning system in the spring and the heating system in the fall.

HVAC systems can produce various noises for several reasons. Common causes include loose or worn parts, debris in the system, issues with the ductwork, or a need for lubrication. If your system is making unusual sounds, it’s advisable to have it inspected by an HVAC repair professional.

You can improve the efficiency of your HVAC system by regularly changing or cleaning the air filters, ensuring your home is properly sealed and insulated, using a programmable thermostat, keeping vents unblocked, and scheduling regular maintenance checks.

A central air conditioner cools your home using a single unit that forces air through ducts, while a ductless mini-split system provides zoned air conditioning (and often heating) without the need for ductwork. Mini-split systems have an outdoor unit connected to one or more indoor units, allowing for more precise temperature control in individual rooms or areas.

The lifespan of an HVAC system depends on its type, brand, how well it has been maintained, and usage patterns. On average, a furnace can last 15-20 years, central air conditioners about 10-15 years, and heat pumps 10-15 years. Regular maintenance can help extend the life of your system and help you avoid expensive HVAC repair jobs. 

While it’s physically possible for a skilled DIYer to install an HVAC system, it’s generally not recommended due to the complexity of the installation, potential safety risks, and the possibility of voiding warranties. Professional installation ensures that your system is installed correctly, safely, and in compliance with local building codes and regulations.

SEER stands for Seasonal Energy Efficiency Ratio. It measures the efficiency of air conditioning systems in the United States. A higher SEER rating means greater energy efficiency and lower operating costs. As of 2023, the U.S. Department of Energy requires new air conditioners to have a minimum SEER rating of 13 to 14, depending on the region.
