For many homeowners, a mini-split heating and air conditioning system is a convenient way to keep your family comfortable without the need for major construction. Perfect for garages and home additions, these ductless systems only require wall space and an outdoor compressor unit to provide cool air all summer long. However, it doesn’t mean they don’t require maintenance. Neglecting to have simple tasks done – like cleaning drainage systems or replacing air filters – can lead to bigger and more expensive system breakdowns.

When you need mini-split repair in southern Maine, your first call should be to Heritage Home Service. Our trained experts understand how every make and model of mini-split systems work and can help you troubleshoot the root cause of your issues. When you schedule your service call, we’ll get the job done right the first time and bring your system back to running like new.

FAQs

  • Ductless Mini-Split Repair Services for Southern Maine

    Also known as a ductless air conditioner, mini-split air conditioners are great for rooms where you want better climate control and airflow, without the need to construct new ductwork. Great for home additions or garages, these units provide cold air with only an outdoor compressor attached to the unit. For that reason, they can stand alone anywhere in your home and are more energy efficient than adding central air ducts into the additional room.

    When it comes time to get your ductless mini-split system repaired, Heritage Home Service is the expert team you can trust to make it right. Our technicians continually train on the latest technologies, giving us the advantage in understanding what goes wrong and how to repair them efficiently. When you need to get your mini-split AC system back to brand-new condition, turn to our experts to get the job done right the first time.

  • What Are the Most Common Mini-Split Repair Issues?

    When working correctly, mini-split systems are a great addition to rooms that need airflow. When they are down, it can create major discomfort for everyone. Here are the most common repair issues we see:

    • Clogged condensate line: Your condensate drainage lines are designed to move moisture out of your unit to keep it working efficiently. If water is starting to build up around your mini-split unit, it may be time to get your condensate line cleaned of mold or other debris.
    • Strange noises from the indoor or outdoor unit: Mini-split systems are designed to operate smoothly and quietly all year long. If it starts making loud noises, it could be a sign that the plastic housing is wearing down, or the unit is continually running in de-icing mode.
    • Strange smells coming from the indoor unit: Foul odors coming from your mini-split unit – such as mildew, fishiness, or vinegar – could mean there’s one or more fluids leaking inside your system. Mold, mildew, coolant, or even electrical issues may be present and need immediate attention.
    • System not cooling or heating: If your mini-split system is running but not blowing conditioned air, there may be a broken internal mechanism to blame. Malfunctions could arise from a range of issues, such as a blocked filter or broken compressor.
    • System not keeping up with demand: If your mini-split AC system isn’t able to blow cold air when you need it, you could be facing a broken internal thermostat or compressor. Either situation will require professional repair to get your unit properly functioning again.
    • System not turning on: If your system is not turning on, it could be a simple problem to repair. Check your electrical panel to ensure no breakers are off, and ensure the batteries in your remote still have power. If you still can’t get it to work, it’s time to schedule a service call with Heritage Home Service to troubleshoot the issue.
  • How Often Should I Have My Mini-Split Serviced?

    Similar to your central air conditioner, your ductless mini-split system consists of mechanical parts that will wear down over time. As a condition of keeping your mini-split warranty active, most manufacturers require you to get professional maintenance done once per year. A service call during the spring or at least before the hot summer months can help keep your unit running cool and clean throughout the season and diagnose any small problems before they become expensive repairs.

  • Can I Maintain My Own Mini-Split System?

    There are some regular tasks any mini-split owner can do, like keeping the system clean of moisture and debris, along with maintaining the area around the outdoor unit. However, more complex maintenance tasks – like changing air filters, cleaning drainage lines, or replacing key parts – should always be left to the experts. The technicians of Heritage Home Service know mini-split systems inside and out, and can keep your system running strong with one service call.

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!
