What are Ductless Mini Split Systems?

A ductless mini-split system is a type of heating and cooling system that provides climate control to individual rooms or zones without using traditional ductwork. These systems are commonly used in homes, additions, garages, finished basements, older homes without ducts, and spaces where homeowners want more efficient temperature control. A typical ductless mini-split system has two main components:

 

  • An outdoor unit that contains the compressor and condenser
  • One or more indoor air handlers mounted on a wall, ceiling, or floor

 

The indoor and outdoor units are connected through a small conduit that carries refrigerant, power, and drainage lines.

Benefits of Mini-Splits

  • Efficiency: Mini-split air conditioners offer outstanding energy efficiency compared to forced-air systems, as they don’t lose energy through ductwork.
  • Zone control: Each mini-split you add to your home acts as a zoned cooling system for that area. This means you can get granular temperature control over different parts of your home.
  • Simple installation: Mini-splits are quick and simple to install, especially when compared to conventional air conditioners. This makes them a quick, easy addition to remodels, renovations, and new builds.
  • Advanced indoor air quality: New mini-splits feature advanced air filtration, helping improve indoor air quality (IAQ) and protect your respiratory health.
  • Quiet: Mini-splits run very quietly compared to central air conditioners.
  • Versatile heating and cooling: Many mini-splits are heat pumps, which means they can efficiently heat and cool depending on the mode they’re set to.

 

When to Repair vs Replace Mini Split Systems

We always advocate repairing systems when possible, as there’s no reason to replace a system that could last longer with basic servicing. However, mini-splits will eventually need to be replaced. Signs your system should be replaced include:

 

  • Mini-split is older than 10–15 years
  • Energy bills continue to rise despite no change in HVAC usage
  • Mini-split is frequently breaking down
  • Mini-split is performing poorly or unevenly
  • Mini-split is making loud noises while running

 

If you spot these signs, contact a mini-split professional. They’ll inspect the system and let you know whether it can be repaired or if it’s time to invest in a new system.

Ductless Mini Split AC vs Central AC

One question we often receive is whether a central AC or a ductless mini-split is the better choice. While central air conditioning offers cooling across a wider area and is controlled by a single thermostat, it also has downsides. Central systems require ductwork to function, which is a major expense if it’s not already in place or requires significant repairs. Central air conditioners also consume more energy, make more noise while running, and cost more.

 

Mini-splits are highly efficient and offer great zone control, but they can only cool a single room. If you want to ensure even cooling throughout your home, you would need multiple, individually controlled mini-splits. If you’re not sure which option is right for you, an HVAC technician can perform a home energy assessment and cooling evaluation to help you make the decision.

DIY Mini Split Repair vs Professional

Some mini-split maintenance and repair jobs, such as changing the air filter or cleaning the system housing, are safe and easy to do yourself. But for anything more advanced and involved, you should rely on professionals instead. This includes deep cleaning of the system, refrigerant checks, line repairs, and work on the system’s electrical components. Attempting to DIY these repairs without the right tools and knowledge can result in injury or damage to your unit.

DIY maintenance tips

A regular maintenance routine helps keep your mini split AC running smoothly. Try these easy DIY maintenance tips:


  • Clean mini split filters every two to four weeks by gently wiping them down with water, allowing them to dry, and replacing them inside the unit.
  • Wipe down the outside of the unit using a soft, dry cloth.
  • Remove debris, such as brush, leaves, and other vegetation, from around the exterior unit. 

 

When to call an AC pro

While DIY maintenance is a great way to support your ductless mini split, it’s always best to call a pro for annual maintenance and any repairs. Ductless mini split systems have many delicate interior components that can be easily damaged by DIY repairs, so if you have to unscrew anything to access a part, it’s best to leave it to a licensed technician.

 

Professional AC maintenance and repairs help prolong your system’s lifespan, ensure it meets safety standards, and keep your warranty valid so you can save on repair costs.

Mini Split Rebates for Marlborough Homeowners

As a Mass Save® Home Performance contractor, we can help you take advantage of energy rebates that help you save hundreds or even thousands of dollars when you install a new, energy-efficient HVAC system.

  • Poor airflow from the mini-split
  • Insufficient heating and cooling

If you spot any of these issues, contact a repair pro promptly. The sooner you get the system repaired, the less likely you’ll need a premature system replacement.

Arron came over a couple ago and after cleaning the mini split he suggested that the internal parts be washed out. He showed me the process and it looked quite intensive so I did. Today Arron and co-worker Mike and did the process. Below are the pictures that show how dirty these 3 year old units were and these great hard working, great personality guys worked. I am glad to be a customer of Endless Energy and these 2 great employees and the rest of the company.

Your guys were here yesterday to upgrade the insulation in my home. They did a great job, left the place cleaner than they found it, and even saved me some attic floor space that I expected to lose!
Response from the owner:Thank you so much for your wonderful review! We're thrilled to hear you had a great experience and appreciate your support. We look forward to welcoming you back soon!
Our experience working with Endless Energy was excellent from start to finish. They just installed two heat pumps in a non-profit conservation building in Plymouth. Our sales rep, Nate M., was knowledgeable, thoughtful and really listened to our questions. He responded quickly to email and voice mail. Our building is older and had some quirky additions. I had confidence that Nate's recommended equipment would meet our needs.

The installation team, led by Ethan J., was outstanding. Ethan had to remove an old oil burner that was full of soot - a messy, messy job. They did an excellent job removing the old and installing two new heat pumps - one for a main building and a smaller one for the addition. What impressed me was Endless Energy's depth of staffing - we had 3 installers, 2 electricians, 3 managers (install, QC, & service) on-site reviewing the work in progress.

Because of the soot from the old burner, the techs left footprints on some of the carpet before they put down dropcloths. The install manager saw them and told me Endless would arrange for carpet cleaning. I even received a call from the COO saying she was aware of the soiled carpet and would have someone contact me to set up a cleaning.

When the job was done, QC manager Jeff T. spent over an hour walking us through the operation and maintenance for each heat pump, including tips on how to run them most efficiently. We are thrilled with the new systems. I would recommend Endless Energy to anyone interested in upgrading to a heat pump. They really have their act together.
