Ductless Split Systems Heat Pumps

Mini-Splits: Flexible Cooling & Heating Combo Anywhere You Need It

Do you need cooling or heating in a single zone of your house that's ductless or requires individual climate control? Space-saving, quiet & energy efficient, ductless mini-split systems are a great solution! Perfect for an addition, garage, or your entire home.

We're Stramowski Heating and Cooling, your guide to reliable cooling & heating solutions that offer cost savings and peace of mind. Explore the benefits, understand how they work, and uncover potential rebates that make a mini-split a smart solution.

What Is a Ductless Mini-Split?

A ductless mini-split is an extremely efficient cooling and heating system for any room in your home. Like a heat pump, instead of burning fuel, it absorbs heat from the surrounding air to cool / heat, using refrigerant, a condenser, and electricity only.


Picture of a home's mini-split system's components

A mini-split consists of an outdoor unit (heat pump condenser) and one or more indoor units in the room(s) being cooled or heated. The units are connected by pipes (lines) carrying refrigerant (coolant). In summer, the refrigerant absorbs indoor heat and releases it outside. In winter, the opposite occurs, warming your indoor space.

What Are the Benefits?

  • Can use in a ductless home for the whole home or just one zone (one or more rooms)
  • Can use in a ducted home in a zone (one or more rooms) with poor or no cooling / heating -- perfect for an addition or attic
  • Space-saving, since no bulky ductwork is required
  • Flexibility in placing the indoor unit on a wall or ceiling
  • Much quieter than traditional systems
  • Energy efficient, so may be more environmentally friendly compared to other climate systems
  • Remote controlled climate
  • Since it runs on electricity only, it may be a cost-friendly option, depending on your local electricity costs
  • There are federal and state offers rebates for energy efficiency upgrades
  • Improved air quality for some models that offer advanced filtration systems

Who Might Need a Mini-Split (Heat Pump)?

People who:

  • have additions, attics, or garages that have no ducts
  • want a zone that's cooled / heated separately from the rest of the house
  • have a zone with poor cooling or heating
  • have older homes with no ducts
  • want a new heat pump like cooling & heating system

How Efficient Are Mini-Splits?

Modern mini-splits are significantly more efficient than many traditional cooling & heating systems, which may translate into energy cost savings. Take a look:

Cooling Efficiency (higher Seasonal Energy Efficiency Ratio (SEER) means higher efficiency):

  • Typical range for modern mini-splits is 18-38 SEER
  • Window ACs are SEER 6-12 & central ACs are SEER 13-25

Heating Efficiency (higher Heating Seasonal Performance Factor (HSPF) means higher efficiency):

  • Typical range for modern mini-splits is 8-14 HSPF
  • Electric furnaces are HSPF 3 & gas furnaces are HSPF 7-9

Overall High Efficiency is due to several factors:

  • Inverter technology: Adjusts compressor speed to match demand, reducing waste
  • Variable refrigerant flow (VRF): Allows individual control of room temperatures
  • Ductless design: Eliminates duct losses, which can be significant in ducted systems
  • Maintenance: Regular maintenance ensures optimal performance and efficiency

Did you know that...

...keeping your mini-split's air filter(s) clean not only improves your air quality but can also improve the efficiency of the mini-split itself?

Keeping air filters clean results in:

  • Reduced pollutants: the filters trap airborne contaminants.
  • Odor control: the filters can help absorb unpleasant smells.
  • Improved system performance: airflow is optimized so the unit operates smoothly.
  • Extended equipment lifespan: a clean filter protects your HVAC system from build-up, preventing wear and tear, and extending its lifespan.
