Mini-Split Maintenance in San Gabriel Valley, CA

Is your ductless mini-split system struggling to keep your space comfortable? Call Cypress Air Conditioning at 626-963-9810 for expert mini-split maintenance in San Gabriel Valley and nearby service areas.

Mini-split systems are a smart, energy-efficient investment—but like any HVAC system, they require regular care to operate at peak performance. Without routine service, dust, debris, and wear can build up, causing your system to work harder, increasing energy use, and shortening its lifespan.

Semi-annual maintenance keeps your mini-split running smoothly, reduces the risk of costly repairs, and ensures consistent comfort all year long.

At Cypress Air Conditioning, we take a comprehensive approach to mini-split upkeep. Our skilled technicians follow a detailed checklist to ensure your system is clean, safe, and operating efficiently.

Here’s what you can expect during a mini-split maintenance visit:

  • Complete System Inspection – We check all indoor and outdoor units, electrical components, and refrigerant levels.
  • Electrical Safety Check – We detect and address any potential hazards to keep your system safe and reliable.
  • Filter, Coil & Component Cleaning – We clean air filters, evaporator and condenser coils, and fan blades to boost performance and airflow.
  • Thermostat Calibration – We ensure accurate temperature readings for better climate control.
  • Lubrication & Adjustment – Moving parts are tuned and lubricated to prevent wear and maintain smooth operation.

After your service, we provide a full maintenance report, including any recommendations for repairs, part replacements, or future service needs.

Keeping your mini-split system in top condition offers several long-term benefits. Here’s why scheduling routine maintenance is a smart investment:

  • Longer System Lifespan – Regular service reduces wear and tear, helping your mini-split last longer.
  • Improved Efficiency – A clean, well-maintained system runs more efficiently, lowering energy use.
  • Fewer Repairs – Preventative care reduces the chance of sudden breakdowns or expensive issues.
  • Thermostat Calibration – We ensure accurate temperature readings for better climate control.
  • Cost Savings – Maintenance helps you avoid surprise repairs and delays the need for system replacement.
  • Healthier indoor air – Clean filters and coils mean better air quality, reducing allergens and irritants.
  • Hassle-Free Service – Our technicians arrive on time and work efficiently to minimize disruptions.

Customer satisfaction is our top priority, and we stand behind the quality of our work. If any issues arise after your mini-split maintenance check-up, simply contact us. Our service manager will promptly address your concerns and resolve the issue to your satisfaction.

Customer Reviews

Our Customers Love Our Service . . Here’s Why

  • The job was promptly done

    Cypress Heating & Air texted that the technician was on his way, including a photo of him. Joshua arrived on time and replaced the filter for the furnace; necessary after the big Eaton fire. He inspected the system and used the blue booties over his shoes.
    MG in Pasadena, CA

  • Professional and on time

    Just had service from Joshua for my annual maintenance. He was very professional and did an excellent job. Would highly recommend him and Cypress. I have been a customer for over three years.
    Deborah in Glendora, CA

  • The technicians are great

    We have used Cypress for a few years now. We had an issue with our A/C and Joshua did a thorough inspection, was able to troubleshoot the issue and our A/C was up and going in no time. Great experience and service!
    James in Los Angeles, CA

  • Fast and efficient

    I had called the company that originally installed my mini-split system and they told me that I would have to wait for a month for an appointment. I called Cypress heating and they were here in two days. They took care of my issue and now I’m a loyal maintenance member.
    Luz in Arcadia

  • Made everything easy

    Got my second service from Cypress so they could check my heater as the winter cold sets in. Joshua did an excellent job. Came right in the time window agreed upon, gave me some good practical information on my unit, replaced the filter, and was able to make sure the system was running correctly.
    Pat in Monrovia, CA

  • Reliable and long-lasting

    Cypress Heating & Air has grown since I first meet Bob in 1994 and I see their trucks and vans everywhere. I still receive the same great service and look forward to continuing using Cypress Heating & Air for years to come.
