Ductless Mini-Split Maintenance Tips

Our Northern Virginia HVAC Experts Will Keep Your System in Tip-Top Shape

To some, ductless cooling systems may seem like a new home-comfort technology, but these energy-saving solutions have been used worldwide for more than 30 years—and their popularity is growing. That’s because these systems offer homeowners a number of advantages with energy-efficiency at the top of the list. However, if you’re not scheduling routine ductless mini-split maintenance service from our Northern Virginia cooling experts at HVAC & Plumbing Unlimited, your unit’s performance—and your energy budget—will suffer. If you’re having problems with your ductless cooling system, contact us today by calling (703) 337-4892.

Why Ductless Mini-Split Maintenance Is Important

As with a traditional air conditioner or heat pump, ductless units require routine maintenance to ensure optimal performance. These systems should be checked in the spring, before the peak cooling season. Since ductless heat pumps cool and heat, they require a checkup in both the spring and the fall. When cared for properly, a ductless mini-split system can last 12-15 years. Additionally, proper routine maintenance can also boost your system’s performance as much as 10-15 percent compared to the performance of a neglected unit.

What You Can Do

One thing you can do is monitor the condition of your air filters. These must be replaced—or cleaned, if applicable—every one to three months depending on usage and local conditions. For example, if you have pets or allergy sufferers in the home, filter changes may need to be more frequent. Check the manufacturer’s specifications for your ductless system for recommendations. You can also keep the outdoor unit free of debris and overgrown vegetation. Ideally, the cabinet should have a clearance of four feet or more to ensure proper airflow. Without the free flow of air, the compressor can overheat and cause damage to the system. Debris buildup can also cause the coil to freeze, which prevents proper operation. These items would be checked during our routine maintenance inspection, but you can help out by trimming away growing plants and clearing away leaves.

Our Professional Ductless Mini-Split Maintenance Service

Do-it-yourself maintenance is not enough to ensure optimal long-term performance. If you want to enjoy the savings and comfort of a ductless system, scheduling routine maintenance is imperative. At HVAC & Plumbing Unlimited, our Northern Virginia ductless mini-split specialists will do the following to keep your unit in top operating condition:
  • Check, clean, or replace your air filters as necessary.

  • Clean your indoor and outdoor coils, if necessary, using specialized brushes and cleaning solutions.
  • Check your drainage lines for clogs.
  • Check your refrigerant lines for potential leaks.

  • Inspect your refrigerant line insulation.
  • Inspect your electrical terminals.
  • Tighten any necessary connections.
  • Apply a nonconductive coating, if necessary.
  • Lubricate your motor parts to prevent any unwanted friction.
  • Calibrate your thermostats for accuracy.
