FAQs

  • Ductless Mini-Split Repair Services for New Hampshire

    A mini-split air conditioner is also called a ductless air conditioner because it doesn’t require a connection to your central air system to operate. Instead of running through your home air conditioning unit, these stand-alone systems are installed on the wall and connected to an outdoor compressor, making them perfect for home additions or areas where it would be otherwise inefficient to provide regular air conditioning (such as a garage or large shed). These systems require less power to run, also making them energy-efficient for any room.

    With deep experience in installing and maintaining mini-split air conditioning units, Heritage Home Service is New Hampshire’s trusted team for all types of mini-split repairs. With regular training courses at our onsite academy, our technicians are knowledgeable on all the latest mini-split models and can troubleshoot most common problems with ease. When it’s time to get your mini-split system back online after a long winter, or you need a quick repair to stay cool in the summer months, turn to the experts at Heritage Home Service to get the job done right.

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

    Mini-split air conditioning systems are designed to run efficiently throughout the spring and summer months in rooms requiring additional airflow. But with regular use, parts can wear down or systems can get blocked, requiring professional repair. Here are the most common issues we see in mini-split systems:

    • Clogged condensate line: Condensate drainage lines whisk excess moisture to prevent water damage to your mini-split unit. If water is pooling near your unit, or there are visible leaks in the condensate line, it is time to get it cleaned out to stop mold or other debris blocking the water flow.
    • Strange noises from the indoor or outdoor unit: Your mini-split system is designed to work quieter than your central air units, making them nearly silent when working correctly. If your unit starts making noticeable noises, it could mean the plastic housing is wearing from expansion and contraction, or the de-icing mechanism needs to be repaired.
    • Strange smells coming from the indoor unit: If the air coming out of your mini-split air conditioner starts smelling odd, it’s a sign your system needs to be repaired. A rotting smell indicates mold or mildew issues, while a vinegary smell suggests there is a coolant leak. If there is a fishiness in the air, your system could need immediate electrical repairs.
    • System not cooling or heating: If the air coming out of your mini-split system isn’t cold, a blocked filter or broken compressor could be to blame. Our technicians can check all of your internal systems to determine where the problem is and can offer you the best options for repair.
    • System not keeping up with demand: If your mini-split AC system can’t consistently blow cold air, you could be dealing with a broken thermostat or compressor. These mechanical parts must be replaced by an expert technician.
    • System not turning on: If your system is not turning on, it could only need a simple fix, such as changing the battery in your remote control or ensuring breakers on your electrical panel are in the “On” position. If your system still refuses to turn on after checking everything, you should schedule a service call today.
  • How Often Should I Have My Mini-Split Serviced?

    Just like your home’s central air system, your mini-split system needs to be serviced on a regular basis. Most manufacturers require at least one annual maintenance call per year to keep the warranty active. Scheduling a service call at the beginning of the warm season – somewhere between mid-spring and early summer – can ensure your system works correctly throughout the year. But if your system breaks down, stop using the mini-split air conditioner until it can be serviced by a Heritage Home Service technician.

  • Can I Maintain My Own Mini-Split System?

    There are some easy maintenance tasks any owner can do. Keeping your mini-split unit clean and the outdoor compressor clear of any debris goes a long way to ensure your system keeps running strong. More complex maintenance tasks – like changing air filters, cleaning and repairing drainage lines, or replacing fans and compressors – should always be left to the experts. The friendly team at Heritage Home Service can help you diagnose any problems and provide the right fix in 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!
