New England is known for their historic homes with over a century of stories to tell. But many of these spaces lack one key modern amenity: Central air conditioning to keep your home comfortable during the summer months.

For many years, the only solution to beat the heat were bulky and loud window-mounted AC units. While they were effective, they lacked efficiency. Thanks to modern technology, homeowners now have a new option for home cooling: Mini-split air conditioning systems.

Also known as “ductless” air conditioning units, mini split installation is a quiet and efficient way to provide homes with comfort throughout all the seasons. These systems can work in concert throughout your home to provide zone coverage where you spend the most time inside.

Heritage Home Service is the top mini-split installation company in Maine, and one of the few Mitsubishi Diamond Dealers in Southern Maine. If it’s time to upgrade your air conditioning system, call us today for a free consultation about how a mini split air conditioner and heat pump may be the best solution for your home.

FAQs

  • How Do Mini Split Installations Work?

    When you call Heritage to schedule your free consultation, our experienced technicians will inspect your current home in order to understand how a mini split system can work best for you. Some of the questions you can expect includes:

    • What are your current heating and air conditioning systems?
    • Is this replacing an old system or is this a new installation?
    • Is ductwork already installed in your home?
    • How regularly do you run your heating and air conditioning systems?
    • Are you considering a single-zone or multi-zone system?
    • How many indoor units do you anticipate needing?
    • Would you like to add smart home integrations or air quality upgrades?

    With this information, we can create a recommendation for your home, answer your questions, and provide an installation quote on the spot. We can also discuss cost, help you arrange for financing, or guide you through applying for tax credits you could qualify for.

    In many situations, we can schedule your mini split installation as soon as the next day! When you schedule your mini split installation, our team will call before we arrive in fully-stocked vehicles ready to get the job done. A single-zone mini split installation can take as little as two hours, while multi-zone systems may require a little more time.

    Once the installation is complete, we’ll do all the cleaning up and leave your home better than we found it. Our technicians will give you step-by-step instructions on how to use your new mini split system, and only leave once your questions are answered. Should you have any problems after installation, call us back – we’ll do what it takes to make it right!

  • Why Should I Consider a Ductless Mini Split AC System?

    No matter the age of your home, there are several reasons why you should consider upgrading to a mini split air conditioning system.

    Easy to Install
    A mini split system packs all the power of a traditional air conditioning system into a smaller package. Mini splits can be installed in any room of your home within a reasonable distance of the outside unit, creating zones to provide cooling in your common living spaces. Outdoor units can also be installed in many different configurations, including on the ground, on the roof, or mounted to a well.

    Provides Cooling and Heating
    While some mini split systems only provide air conditioning, our preferred units also work as heat pumps to keep your home warm during the cold winter months. Our systems can work at temperatures as low as -13°F, keeping your family safe and comfortable no matter what the weather brings. Mini split systems can also work alongside a furnace or boiler system, giving you more options and greater overall efficiency.

    Create Zones Throughout Your Home
    A ductless mini split system can be set up to run independently to heat and cool one room in a single-zone configuration, or alongside several other units in a multi-zone setup. If you are looking to provide climate control to only one room or an addition to your home, a single-zone setup can provide the right solution without a complicated installation. Should you need a whole-home heating and cooling solution, a multi-zone mini split installation gives you the benefits of room-to-room control and great energy efficiency.

    Cost Savings From Energy Efficiency
    Compared to traditional central air conditioning systems, mini split systems can reduce your energy consumption by up to 30%. A traditional air conditioner works to cool large areas of your home, and can hike your energy bills if there are issues with the unit or leaks in your existing ducts. Because a mini split system doesn’t rely on ducts, they don’t need as much power to keep your home comfortable.

    Quieter Than Window-Mounted Units
    Traditional window-mounted units are often loud, which can be unpleasant in the day and hard to live with at night. A Mitsubishi mini split system is among the quietest and most efficient available on the market today, keeping your family comfortable all season long without the unbearable noise.

    Easy Upgrades and Add-On Units
    Mini split systems are modular and can be upgraded or added to with little difficulty. Both single-zone and multi-zone systems are controllable with remote controls or smartphones, and can be fitted with enzyme filters to reduce allergens in your home. With one system, you can have full control over your comfort no matter where you are.

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

    Traditional air conditioning units use a single outdoor unit to cool air through a refrigerant chamber while removing moisture. The air is then distributed through a duct system to cool large areas of your home. These systems can work well, but can be inefficient due to duct leaks or outdoor unit breakdowns.

    A ductless mini split system utilizes one or more indoor evaporators to create comfort zones in your home, all powered by a single inverter-controlled, variable-speed outdoor compressor. Unlike a traditional HVAC system, the compressor only works when you turn on the different zones. By working continuously and only speeding up or slowing down when units are on, a mini split system saves you money through efficiency by blowing air directly where you need it without losing energy through the ductwork or other potential leak points.

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

    Yes – Many homeowners will use a mini split system alongside a central air conditioning system for the cost benefits and convenience. A single-zone mini split system can add heating and air conditioning to any part of your home. In areas of your home without existing ductwork, such as a garage or any home additions, a ductless system can provide climate comfort without extensive construction or high installation costs.

  • What Maintenance Do Ductless HVAC Systems Need?

    Like other heating and air conditioning systems, ductless mini split systems also need annual maintenance and inspection for repairs. Scheduling an annual service call allows a trained and licensed technician to clean your system, change any necessary filters, inspect the mechanical components, and go through small repairs before they turn into major problems. A well-maintained mini-split system can last 15 years or longer, helping you get the most out of your investment.

Gavin and Mohammed were exceptional in their customer service. Gavin explained my situation to me with excellence and his explanation was clear and well executed. I could tell he was well equipped with knowledge and was confident in his delivery of service which made me feel confident. Gavyn’s personaity made me feel comfortable and secure and was like a ball of sunshine on a cold rainy day.They both were gentlemen, professional and respectful. I’ve been living in my home for 34 years and have never been so impressed with the dynamic service that was provided to me by Gavin and Mohammed ( Haritage Home Service). The initial call process from Heritage was fast and well organized. My experience was nothing short of exceptional to the point where I never thought I’d be so excited to have new shiney, copper pipes! Don’t hesitate to call Heritage and change to them as your new home service company!
