Reliable Mini-Split Maintenance for Year-Round Home Cooling

Mini-splits deliver efficient, room-by-room cooling—but like any home investment, they work best with regular attention. At Moss Heating, Cooling & Plumbing, maintenance isn’t just about keeping equipment in shape—it’s about making the entire experience easier, clearer, and more reassuring for you. Our technicians take the time to inspect each component carefully, explain their findings, and make sure you feel confident in every step we take. We focus on preventing problems before they start, helping your unit last longer and perform consistently through the season. Every visit is completed with the care and respect your home deserves, because your experience matters just as much as the result. When you choose Moss, you’re choosing a team that listens, follows through, and always puts homeowners first.

Our Residential Mini-Split Maintenance Services

Routine care prevents performance drop-offs and helps avoid expensive repairs. Moss Heating, Cooling & Plumbing takes a detailed, room-by-room approach to ensure your unit is operating as efficiently and effectively as possible. We check airflow, address any signs of buildup, and look for early indicators of wear. Each tune-up is tailored to your home’s layout, giving us the chance to focus on the areas that matter most to you. Our goal is to help you maintain consistent indoor conditions while minimizing future disruptions.

  • Filter Cleaning and Inspection: Clean filters promote airflow and reduce system strain. We’ll clean or recommend replacements as needed to support overall system health.
  • Coil and Fan Cleaning: Dust buildup can limit performance and increase energy use. We remove debris to help restore smooth, efficient operation.
  • Performance Testing: Each indoor unit is checked to ensure it’s cooling properly and responding to settings. Our team makes adjustments as needed for consistent results.
  • Electrical Component Check: We inspect all wiring and electrical connections for signs of wear or loose fittings. Safe operation depends on secure and stable power flow.
  • Drain Line Flushing: Blocked drain lines can cause leaks or moisture issues. We flush the lines to prevent water buildup around the unit.
  • Sensor and Control Review: We test the unit’s sensors and thermostat connections. Accurate temperature readings are essential for efficient cooling.

Great company to deal with. Easy set up and the tech, Arturo was excellent. Did. It try to “sell” unnecessary repairs. He was polite, quick and a pleasure to do business with. The company has good communication and checks in with you for your next service. They have great promotions if you catch them early and are very reasonably priced. I highly recommend Moss Heating & Cooling

My unit had some blown fuses and Ethan came through and took care of everything and confirmed it wasn't the blower.
He even stayed longer after the system was turned back on. Glad I paid for the extended warranty.

Steve Moss is a good man. I had an urgent matter with my furnace. He was tied up in a meeting when I called but he promptly returned the call when I left a message. He then made it a priority to come out to house the same morning I called, fixed the problem in a jiffy for a fair price and was thoroughly courteous and professional all the way through. Top notch !
