Our Ductless on Every Job campaign is in full swing, so we’re back to educate contractors on yet another solution where they could consider ductless as an answer to a sales call’s need. This week, we’re focusing on how ductless can solve the hot and cold spots dilemma.

Even with the doors and windows closed, the homeowners still feel drafts inside. They’re comfortable in one room, too hot in another and cold everywhere else in the house. Sound familiar? If your customer is describing these common annoyances, rest assured that although the cause of hot and cold spots may be difficult to identify, there is one easy and effective solution – installing a ductless system.

Uneven temperatures in a house mean one thing: the home’s HVAC system is not working properly. If left unaddressed, energy will undoubtedly be wasted and homeowners will end up spending way more than they should on their utility bills. So, to help your customers win the battle for comfort, here are the common sources of hot and cold spots and how to explain to homeowners that ductless technology can rid the home of them:

  • The HVAC system isn’t properly sized. Systems that are too small cannot provide sufficient amount of air to heat and cool the entire home, and bigger is not always better when it comes to an HVAC system. Short-cycling, shortened lifespan and higher energy and operational costs are all results of inappropriately sized systems. With Mitsubishi Electric’s ductless systems, however, homeowners don’t have to worry about running into these issues. We offer a wide range of capacities to match the specific room size and requirements of the home. With our advanced zoning technology, multiple indoor units can be installed and individually controlled, allowing homeowners to condition only the occupied spaces and not waste energy conditioning the vacant areas. Whereas traditional HVAC systems only operate at either zero percent or 100 percent, our ductless systems use INVERTER-driven compressors that ramp up quickly to provide the energy necessary to achieve the heating or cooling demand then varies its speed to maintain the desired comfort level. The i-see™ Sensor found on some indoor units scans the room’s ambient temperature readings, detects any disparities and then adjusts the airflow to provide uniform comfort throughout the room. With these advanced technologies, the HVAC system performs only at the minimum energy levels necessary. Because of this, energy is not wasted when partial-load conditions are present, which is occurs about 97 percent of the time.
  • Leaking or poorly insulated ducts. Research from the U.S. Department of Energy discovered that about 30 to 40 percent of the air traveling through ducts leaks, which negatively impacts both the system’s efficiency and the air quality it provides. Not to mention, holes in the ducts introduce dust, bugs, allergens and other particles so what should be clean, filtered air ends up dirty and unhealthy.
  • Obstructed air vents. Floor or wall air vents blocked by decorations and furniture could also cause temperature swings in a home. Our expansive offering of indoor unit styles and combinations provide the ultimate design flexibility. The system’s components are compact, lightweight and can be installed in small areas, providing more space for interior design by minimizing the unit’s visual and auditory impact. Wall-mounted, ceiling-recessed, horizontal-ducted and floor-mounted indoor unit installation options allow the homeowner to design their space how they want to and not how they have to.

It is no doubt that hot and cold spots are uncomfortable to live with and that is the opposite of what homeowners should feel when they’re in their home. Our ductless system is the one-stop-shop solution to eliminate uneven temperatures and provide the utmost, constant comfort.
