Ductless Mini Split Installation in New Hampshire

FAQs

• What Are the Benefits of Ductless Mini Split AC Systems?

  Easy Installation
  Mini split systems use less space to fit all of the necessary components of heating and cooling equipment without any ducts. Mini-split systems can be installed in any room as long as the outdoor unit is within a reasonable distance. Outdoor units can be installed on the ground, roof, or mounted to the wall.

  Cooling + Heating
  As a side benefit, all of Heritage’s ductless AC systems double as heat pumps during the colder months, providing heating to your home in outside temperatures as low as -13°F. Even if you already have a furnace or boiler, you’ll be able to heat your home with greater efficiency by using the heat pump instead.

  Zoning Capabilities
  Ductless mini splits can be set up to control the temperature in just one room (single-zone) or throughout your home (multi-zone). Single-zone systems are great for additional rooms or a single area that needs better temperature control. Multi-zone mini split systems are a whole-home alternative to central air conditioning, with the added benefit of room-to-room control and excellent energy efficiency. Zoning can meet everyone’s temperature preferences at once, meaning no more fighting over the thermostat!

  Energy Efficiency & Cost Savings
  Central air conditioning distributes air throughout the whole house, so you have to adjust the thermostat if just one room is too hot or cold. These systems have to work even harder if your ductwork has air leaks or was improperly installed. Mini split systems, in comparison, can reduce energy consumption by 30% simply because they don’t need ductwork.

  Quiet Operation
  Our Mitsubishi mini split systems are some of the quietest air conditioners available on the market. Their ability to operate without noise makes them perfect for bedrooms and other quiet spaces. Central and window AC units simply can’t compare!

  Available Upgrades and Add-ons
  Each indoor unit contains its own local temperature sensor and can be individually controlled from a remote control – or, with the correct upgrade package, your smartphone. If seasonal allergies are a concern, they can also be fitted with enzyme filters that eliminate allergens and irritants inside your home.

• The Mini Split Installation Process

  During your free initial consultation, one of our friendly HVAC experts will inspect your home and ask some questions about your comfort needs and preferences:

  • What is your current HVAC system? Will this be a replacement or a new installation?
  • Do you have existing ductwork?
  • How often do you use your HVAC system
  • One or multiple zones? How many indoor units?
  • How important is energy efficiency to you?
  • Are you interested in any smart home or indoor air quality add-ons?

  Based on these factors, we’ll recommend some options, answer any questions you have, and provide a quote. We can also help with the financing process and applying for tax credits you qualify for, if applicable.

  In most cases, we can schedule your mini split installation for the next day. Our HVAC team will update you on our arrival and show up on time in Heritage-branded vehicles. Once we get started, the installation process only takes a couple of hours. Multi-zone systems will take a little longer to install than a single mini split.

  When the installation is complete, we’ll clean up the work area and show you how to operate your new ductless mini split. If there are any problems after we leave, you can call the Heritage office, and we will do what it takes to make things right!

• How are Ductless Mini Splits Different From Other AC Options?

  Ductless mini split systems are configured with one or more indoor units (evaporators) powered by a single inverter-controlled, variable-speed outdoor compressor. The compressor delivers maximum comfort by speeding up or slowing down to meet your specific needs. By continuously working, the ductless AC unit doesn’t waste energy like other traditional HVAC systems. These systems are also known for being efficient because no energy is lost while transporting air through lengthy ductwork.

• Can You Have Both a Mini Split AC and a Central AC Installed?

  The short answer is yes! Even if you have a central cooling system, you can still benefit from a ductless system in areas of your home without existing ductwork such as a new addition, workshop, garage, or finished basement.

  Typically, existing ductwork is not designed to accommodate additions or renovations and therefore is only sized to meet the exact airflow requirements of your existing setup. This makes it either impossible or too costly to add a new “zone” to existing ductwork. In these cases, a mini-split solution may be a better option.

• Are Mini Splits Good for Heating?

  Yes! Most standard units are effective down to about 35 degrees, or you can upgrade to a Hyper Heat system so you can heat your home all year round, even down to -13°F. And depending on the layout and size of your system, ductless heat pumps can actually heat your home more efficiently than traditional fossil fuel systems like gas or oil, saving you money during the heating season.

• What Maintenance Do Ductless HVAC Systems Need?

  Ductless AC and heat pumps need annual maintenance just like any other HVAC system. These services give us the chance to clean your system, inspect all components, and make small repairs before they turn into big expensive problems, ensuring that your mini split continues to work throughout the year. HVAC systems that are routinely maintained operate more efficiently, need fewer repairs, and live longer than those that don’t get the same care.

• What is a ductless mini-split system and how does it work?

  A ductless mini-split consists of an outdoor compressor unit connected to one or more indoor air handlers, delivering heating and cooling without the need for ductwork. Each indoor unit is controlled independently, allowing you to set different temperatures in different rooms or zones.

• Why are ductless mini-splits a good choice for New Hampshire homes?

  Ductless mini-splits are ideal for New Hampshire because modern models provide efficient heating even in sub-zero temperatures, they eliminate energy losses from ductwork, and they are perfect for heating additions, garages, or older homes without existing ducts.

• How many indoor units do I need for my home?

  The number of indoor units depends on how many rooms or zones you want to heat and cool independently. Heritage performs a load calculation and discusses your comfort goals to recommend the right configuration, whether it is a single-zone system or a multi-zone setup.

• How long does a ductless mini-split installation take?

  A single-zone ductless mini-split installation typically takes one day, while multi-zone systems may take 1 to 2 days. The installation requires only a small 3-inch hole through the wall for the refrigerant line, making it far less invasive than installing traditional ductwork.

• Are there rebates for ductless mini-split installation in New Hampshire?

  Yes, ductless mini-split heat pumps often qualify for utility rebates, federal tax credits, and manufacturer promotions, especially high-efficiency cold-climate models. Heritage will help you identify and apply for all available incentives to lower your out-of-pocket cost.
