Home Additions and Your HVAC System

A new home addition is more than adding extra space—it's an opportunity to create customized indoor comfort and energy efficiency for your entire home. Looking at the big picture means considering how upgrades and additions in one area might affect your whole home.

Evaluating your current HVAC System

 

Evaluating your current HVAC System

Start by ensuring your heating and cooling system is appropriately sized to fit a larger space. Whether you're building a new room, converting a garage, or expanding your living space, your current heating and cooling system may not be equipped to handle the added demand.

An appropriately sized system is necessary to operate at the designed efficiency and maintain consistent comfort levels throughout your home. Before construction begins, schedule a checkup with a Daikin Comfort Pro to evaluate your current system's capability and identify any additional heating and cooling needs.

Is it time for a whole-home HVAC upgrade?

While renovating your home, consider upgrading your heating and cooling system. Modern systems with inverter-driven heat pump technology offer multiple benefits, as they are designed to optimize energy consumption and provide consistent, energy-efficient indoor comfort.

A separate, dedicated HVAC system

If your current system is not sized to heat and cool your new, additional space, you may like the option of a separate HVAC system for your home addition. This can help maintain consistent comfort without overburdening your existing unit. A dedicated system also allows for tailored temperature control and a simple installation process—especially when ductwork extension is difficult or costly.

Three modern home HVAC solutions:

Single or multi-zone
ductless mini-split

Daikin AURORA

If you don’t have the space to run ductwork or don’t want major renovations, a high-performance ductless system provides both heating and cooling for individual or multi-room zones. It’s designed to maintain capacity for locations that experience −13°F (−25°C) to 115°F (46°C).

Proper sizing and installation of equipment is critical to achieve optimal performance. Split system air conditioners and heat pumps must be matched with appropriate coil components to meet ENERGY STAR criteria. Ask your contractor for details.

Daikin AURORA

For additions with multiple rooms, the Daikin AURORA multi-zone ductless system can connect up to four indoor units. The adaptive inverter technology minimizes temperature swings, providing consistent cooling and heating for a balanced indoor climate. The Daikin AURORA is compatible with various indoor units, including wall-mounts, ceiling cassettes, floor mounts, and even a ducted concealed unit.

Daikin OTERRA

For homeowners looking for a high-efficiency, single-zone ductless heat pump, the Daikin OTERRA is an excellent choice, offering up to 21 SEER2, 10.2 HSPF2, and 12.5 EER2. Its variable-speed inverter compressor allows for precise temperature control and is designed to provide energy efficiency by adjusting to your home’s real-time heating and cooling needs. The Daikin OTERRA 115V option includes the new Daikin SIGNA flareless adaptor, allowing for a quick, professional installation.

Daikin FIT

With a low-profile, space-saving design, the Daikin FIT heat pump is a quiet, smart, efficient HVAC unit for ducted homes. The outdoor unit looks different than traditional systems, because it is different. Its inverter technology provides efficient, consistent temperature control, precisely adjusting to meet the specific demands of your home and/or new addition.  Paired with the Daikin ONE+ Smart thermostat, which enables two-way communication with system components and online diagnostics for a seamless user experience, the Daikin FIT system allows precise control over your home’s climate, ensuring even temperature distribution and comfort throughout.

Assess your home's energy performance.

Before adding square footage, it makes sense to assess your home’s current energy efficiency performance. Key areas for a professional to evaluate include:

  • Insulation and Air Sealing
