New Home Central Heating & Air Conditioning System

When planning your HVAC system for a new home construction, you have a range of choices. It's essential to discuss these options with your home contractor before breaking ground and completing the foundation. Let's explore some of the most common types of systems and their costs.

Central AC & Furnace | $16,500 - $35,000

This is still the most common HVAC system type in the US, according to the National Association of Home Builders. It typically includes a gas furnace as the most common heating source, although oil furnaces are used mostly in the Northeast, and electric furnaces are more common in warm climates.

  • Cooling SEER2 range: 12 - 26
  • Furnace AFUE range: 80% and 90% to 99%

The components included in central AC and furnace systems are:

  • Outdoor condensing unit
  • Indoor gas, oil, or electric furnace that also acts as the air handler for air conditioning
  • Evaporator coil in or adjacent to the furnace
  • Supply ductwork to carry treated air to each room and return ductwork to carry it back to the furnace
  • Sheet metal connections
  • Thermostat
  • Gas line from the main to the furnace, electrical wiring, outdoor shutoff, and circuit breaker in the electrical panel
  • Zoning dampers - manual or electric - are extra

Heat Pump System | $17,600 - $32,600

Heat pumps are becoming popular in moderate and warm climates because they efficiently provide both heating and cooling.

Once the rough work passes inspection, the HVAC equipment is installed and inspected. However, the ductwork installation can occur simultaneously to either of these tasks, depending on the crew's size. Here's an estimate of the time crews will spend working in your home:

  • 1-2 Days: Rough wiring, electrical circuits, gas lines (if necessary)
  • 2-4 Days: Ductwork installation
  • 2-5 Days: Heating and air conditioning equipment installation

DIY or Hire a Pro

While most homeowners hire a licensed contractor to install their HVAC system, there are options for DIY. Currently, the only full DIY option available is a DIY mini-split system from MrCool or Klimaire. These systems come with full refrigerant charges, and homeowners can install them by following the provided instructions. However, other systems that require a refrigerant charge should be installed by a licensed technician. Some homeowners with electrical and gas line experience may choose to do some of the work themselves, but it's crucial to have a certified HVAC technician inspect the system to ensure it is done correctly.

Ductwork can also be a DIY project, but it's important to optimize the ductwork layout and ensure proper airflow and balanced temperatures throughout the home.

By considering these factors and consulting with a reputable HVAC company, you can determine the best HVAC system for your new home construction that fits your budget and meets your comfort needs. Remember to prioritize quality, efficiency, and the expertise of the professionals you hire for the installation process.
