What factors affect the cost of a ductless install?

The price of a ductless install varies based on three main factors: unit size, the number of temperature-controlled areas in the home and the efficiency of the selected system.

  • Size of the ductless system: The most important job of an Aiello comfort specialist is to find a ductless system that's sized correctly for your home. The size of the system will depend on a number of factors. But generally speaking, home size is at the top of the list.
  • Number of temperature controlled areas: Ductless systems rely on one or more air handlers to create temperature control zones in the home. The more air handlers a home requires, the higher the cost of the installation. An Aiello comfort specialist will help you find the exact number of air handlers you need, so you won’t have to worry about the comfort of your home.
  • Efficiency of the ductless system: The more efficient a ductless system is, the more you'll save on energy costs per month. That said, systems with higher efficiency ratings also cost more to purchase. Your comfort specialist will give you all the information you need to strike the perfect balance between efficiency and upfront cost.
  • The contractor you hire: Pricing for ductless installations varies from contractor to contractor. These rates are based on a contractor's experience, skill level, training and other factors. The EPA estimates that as many as half of all HVAC systems are installed incorrectly by inexperienced contractors. That's why going with a company you know will get the job done right is always the best choice.

Our 5-star ductless installation process

  1. We perform a free in-home estimate

    Every ductless mini-split installation begins with a free in-home estimate and load calculation. This guarantees the homeowner will not pay extra for a system that's not the right fit for their home. At Aiello, all of our comfort specialists are trained for this critically important job. Equally important, Aiello will text you the name of your comfort specialist along with a photo and a brief bio prior to their arrival. You can even follow your comfort specialist on their way to your home via an easy text link.

  2. We share a variety of replacement options

    Once the in-home assessment is complete, the next step is to share new ductless system options with our customers. Aiello has a selection of mini-split brands and models anywhere in Connecticut. More options mean more chances to identify a system that meets the comfort, convenience, and budget needs of our customers.

  3. We prepare for a successful mini-split installation

    Aiello will order your new system from the manufacturer and apply for any available rebates on your behalf, including Energy Star rebates. We can help you with a financing plan as well upon request. Typically, you'll only need to wait a few days before the system is loaded up on an Aiello truck and sent out to your home.

  4. We give you a 5-star installation experience

    Each installation team puts in a lot of prep work prior to installation day. For our customers, it means better installations completed in a faster time frame with no hassles or confusion. In addition to that, we go above and beyond to protect your property by wearing shoe covers while in your home, laying down drop cloths and completing a thorough clean up to ensure we leave your home as clean or cleaner than how we found it.

Your satisfaction means the world to us

Our goal is to give every Aiello customer a 5-star experience. That's why we ask if we delivered 5-star service at the end of every job. If not, we'll do everything we can to correct that issue before we leave.
