HVAC Basics for New Homeowners

What is HVAC?

If you’re a new homeowner, you may already be aware of the necessity of updating your HVAC system. But what exactly is an HVAC system, and how does it operate?

Heating, ventilation, and air conditioning are also known as HVAC. HVAC systems use a variety of tools, including thermostats, ducting, furnaces, and air conditioners, to heat and cool the entire house.


Depending on the season and your particular comfort preferences, these systems function by circulating air between the inside and outside to keep you warm or cold. The following are some additional advantages of your HVAC system that are commonly overlooked:

  • Cleaning and filtration of indoor air
  • Keeping humidity levels constant
  • Energy efficiency

The Most Common HVAC Systems

Standard Split Systems
Both the outside and inside of the house have a part of these systems. Split systems are frequently the most cost-effective and provide a number of possibilities. A variety of alternative techniques may be used to divide the systems:

  • Air conditioner and furnace: The air conditioner unit is normally put outdoors, while the furnace component is typically positioned within your home. While an air conditioner pulls heat energy from the home and transfers it to the outside air, a furnace burns fuel and disperses it around the house.
  • Heat pump split system: This system, which is typical in milder areas without freezing temperatures, consists of an inside air handler and an outside condenser or compressor. Heat pumps transfer exterior heat into your home during the heating season, and during the cooling season, they remove heat from your home.
  • Furnace and heat pump: This hybrid heating system is a split heating system that uses two heat sources. The heat pump functions in fair weather and shifts to the furnace section when it gets too cold for the heat pump, as is common in colder areas.

Ductless Split Systems
Ductless split systems can be employed in structures without ductwork, in contrast to traditional split systems, which need it. One outside unit and one inside unit coupled by electrical wire and refrigerant tubing make up a ductless split system in its most basic configuration.

Packaged Systems
Packaged systems are totally placed outside, with each component housed in its own container and linked to the ducting via a hole in the exterior wall. Many varieties of packaged systems consist include:

  • Gas/Electric
  • Heat pump
  • Hybrid

Geothermal HVAC Systems
Traditional furnace operation is very unlike that of geothermal heating and cooling systems. Unlike a geothermal heat pump, which uses heat exchange to warm a home instead of burning fuel, a furnace generates heat by burning fuel. A geothermal cooling system uses the earth as a heat sink rather than releasing heat into the air like an air conditioner or air-source heat pump does. Despite being more expensive than conventional systems, these systems have outstanding energy efficiency.

How to Maintain Your HVAC System

In terms of HVAC fundamentals, it’s critical to regularly maintain your HVAC system. Ignoring HVAC maintenance might lead to expensive problems in the future.

The following are maintenance procedures for HVAC systems that all homes should follow:

  • Change Your Air Filter
    Your air filter should ideally be changed approximately every three months. This maintains the efficiency of your system and enhances the quality of the air within your house.
  • Clean Your Outdoor Condensing Unit
    Condensing unit debris should be removed before each new season, and water should be sprayed along the outside to eliminate any dirt or grime accumulation.
  • Clear Around Your Outdoor Unit
    To reduce interference, trim back any vegetation near your outside device. A minimum of two feet should be left between you and any shrubs or trees.
  • Check Your Air Conditioner’s Drain Line
    Remove any obstruction that may have accumulated in the drain pipe of your device. An obstruction in a drain pipe might result in a breakdown and internal leakage.
  • Get Regular Maintenance
    Bring in a reliable HVAC contractor in Princeton, NJ at least once each year to inspect your system. They’ll be able to conduct inspections and deal with any trouble spots. Your HVAC system’s lifespan will be extended and you can wind up spending less money overall if you repair it regularly.

The choice of whether to repair or replace your HVAC system ultimately depends on the circumstances. Think about how much a replacement would cost and find out from a HVAC contractor in Princeton, NJ how much a repair would cost. It can be difficult to choose, but with the appropriate information, you can choose the ideal HVAC for your house.
