TARGET HOT AND COLD SPOTS
Restore consistent comfort in your home
Temperature inconsistencies, such as hot and cold spots, are more than just minor annoyances. They can affect your comfort, impact the overall efficiency of your home’s heating and cooling system, and can ultimately increase your energy usage.
HOT AND COLD SPOTS
A variety of factors may contribute to hot and cold spots in your home, including leaky ductwork, inadequate insulation, blocked vents, improper thermostat placement, and even an incorrectly sized HVAC system.

Five reasons for hot and cold spots.
Here are some common causes for home heating and cooling inconsistencies:
Poor insulation
Without sufficient insulation, conditioned air may naturally escape your home. This makes it challenging for your HVAC system to maintain steady temperatures. During cold winter months precious warmth seeps out through attics and walls, while in summer, exterior heat invades your home. Upgrade your insulation, particularly in attics and exterior walls, to reduce the strain on your HVAC system and create more consistent comfort.
Leaky ductwork
Your central heating and cooling system relies on ductwork to deliver conditioned air throughout the home. Over time, ducts can develop cracks, gaps, and loose connections, letting air escape before reaching certain rooms. These areas may receive less heated or cooled air, causing uneven temperatures.
Leaky ductwork may also force the HVAC system to operate for extended periods of time to reach your set temperature, increasing energy consumption and costs. Hiring a professional to inspect ducts, seal gaps, and perform regular maintenance can help confirm that every room enjoys the proper airflow.
Blocked vents
Surprisingly, vents being obstructed by furniture, boxes, or curtains is more commonplace than you may think. When airflow is restricted, certain rooms may not receive enough conditioned air to maintain the desired temperature. Ensure your vents, both supply air and return air, are open, unobstructed, and free from dust and debris. This simple preventative measure, plus regular filter replacements, enhances air circulation and helps eliminate hot and cold spots.
Thermostat placement
The location of your HVAC system’s thermostat matters more than you might think. Placing it near a drafty window, exterior doorway, heat-generating appliance, or in direct sunlight can cause it to misread the home’s overall temperature. As a result, the HVAC system may shut off prematurely or continue running for too long. A professional should install your thermostat in a neutral, central location to help ensure accurate readings and balanced comfort throughout your home.
HVAC system size
Improperly sized systems can lead to temperature fluctuations. Undersized equipment can struggle to reach set temperatures, leaving certain areas feeling uncomfortable, while a system that’s too large may cycle too frequently, never running long enough to distribute air evenly. Your heating and cooling professional should assess the details of your home to ensure its HVAC system is sized properly.
FIND YOUR DAIKIN SOLUTION
Mini-Split, Central HVAC System or Both?
If you’ve had a professional investigate the insulation, ductwork, vents, and thermostat placement and still experience persistent hot or cold spots, it may be time to focus on your HVAC system.
When considering a Daikin solution to address hot or cold spot in your home, you have three main options:
1. Replace your current central HVAC systems
2. Install a mini-split system(s)
3. Use a combination of a central HVAC and mini-splits.
Upgrading to a modern, properly sized whole-home heat pump system, adding a mini-split to a specific room or rooms, or incorporating both can make a significant difference to address hot and cold spots.
Here are three scenarios that illustrate some of the issues homeowners face, along with targeted Daikin HVAC solutions
Challenges
Large, open-concept living area
Repurposed or renovated spaces 
Inconsistent Comfort
Modern homes often feature open-concept layouts, blending kitchens, dining areas, and living rooms into one spacious environment. While visually appealing, these spaces can experience uneven temperatures due to factors like abundant windows, high ceilings, and varying activities.
Multi-Zone Solution
A multi-zone, ductless mini-split configuration, such as the Daikin AURORA system, offers zoned comfort control, enabling you to create distinct climate zones. For example, you can keep the kitchen slightly cooler to offset heat from cooking appliances, while maintaining warmer conditions in the seating area.
Zoned comfort means you only use energy where it’s needed, reducing operational costs. The AURORA’s compatible indoor units offer quiet operation, keeping the open-concept area peaceful, and advanced filtration options for enhanced indoor air quality.
Benefits
Zoned Control
Let’s you set individual temperatures for up to 4 different areas with one outdoor unit, ensuring every space enjoys a personalized level of comfort.

Blend the indoor units seamlessly with your décor and layout ensuring comfort without compromising style. With over 1,000 possible combinations of interior equipment, you have options that include wall-mount units (such as the EMURA), slim ducted units, floor mounts, ceiling cassettes (such as the VISTA), or a combination.
Inverter-driven compressors
Outdoor and indoor heat-load conditions are constantly changing, affecting your HVAC system’s ability to maintain a comfortable indoor home environment. A variable-speed, inverter-driven compressor in a Daikin system can modulate its performance, like the cruise control on a car. This operation is designed to match the exact heating or cooling conditions to provide outstanding comfort control with smart energy usage, plus low utility costs. With up to 20 SEER2/9.7 HSPF2/12 EER2, the AURORA offers ultra-efficient cooling and heating operation.
Quiet Operation
A peaceful environment helps make it easy to relax, concentrate, or sleep without distraction.
All-Climate Comfort
Living in colder climates doesn’t mean a heat pump isn’t a viable option to heat your home. The outdoor unit of the multi-zone Daikin AURORA heat pump system has been designed to operate reliably in extreme weather conditions, even when it is down to -13°F WB (-25°C WB).
If you have hot or cold spots in an attic suite, a basement studio, or a living space above your garage, each of these spaces has unique heating and cooling demands that may not have been part of the original load calculations for your current system to operate effectively.
Single Room, Mini-Split Solution
Rather than dealing with the mess or cost of major renovations to update your current central HVAC system, a Daikin OTERRA single-zone mini-split offers independent climate control for a single space. The 115V model of the OTERRA is designed for quick installs without overloading the home’s electrical system.

INCONSISTENT INDOOR TEMPERATURES→
Benefits
Comfort in Every Corner
A central HVAC system is designed to handle the main living areas of the home, specifically the spaces with ductwork and that are regularly used. However, supplemental systems target hard-to-heat or cool areas (bonus rooms, sunrooms, basements, additions, or garages) or areas where customized temperatures are preferred, such as a bedroom or a baby’s nursery.
Independent Temperature Control
With a ductless system in a specific space, you can set a different temperature than in the rest of the house. This means you can set your bedroom’s mini-split temperature to be cooler at night or warm up a basement playroom for game night without affecting the rest of the house.
Energy Efficiency
By using an efficient ductless system to maintain comfort in the space that needs it, you avoid overworking the central system to compensate, which can be costly. This may also help avoid excessive wear on your HVAC system.
Adaptive inverter technology
The Daikin FIT central heating and air system, as well as the ENTRA mini split, are equipped with adaptive inverter technology, which adjusts the compressor speed in real-time as necessary to balance indoor comfort and system efficiency.
Quite Performance
No one wants a noisy HVAC system humming in the background or jolting you awake at night. DaikinFIT whole-home systems use smart inverter technology to keep sound to a minimum, especially quiet in ‘Quiet Mode’ with select models running as low as 45 dB(A). And for rooms that need customized temperatures and extra peace and quiet, like a home office, the Daikin ENTRA wall-mounted unit operates at just 23 dB(A), so quiet you’ll barely notice it’s on.
Flexibility
At less than 14” in width and needing only a 4” clearance from an outside wall, the Daikin FIT has a small footprint, making it ideal for spaces where outdoor unit space is limited. Its compact size allows for flexible installation options, including tight balconies or constrained outdoor areas. The ENTRA ductless mini-split is great for a room addition or finished attic or basement, as it eliminates the need for reworking ductwork. A supplemental system handles those areas without expensive remodeling.
