Fast AC Solutions
Expert Ductless AC Services – Repairs, Tune-Ups & More!
We perform detailed system diagnostics, checking compressor health, airflow blockages, refrigerant levels, and sensor calibrations to detect and fix issues before they impact performance.
Refrigerant Leak Detection & Recharge
Low refrigerant reduces cooling and strains the compressor. We use UV dye tests and electronic detectors to find leaks, repair damaged copper lines, and recharge refrigerant to factory specs.
Thermostat & Remote Control Troubleshooting
A miscalibrated thermostat or faulty remote disrupts cooling. We reset, recalibrate, or replace thermostats, troubleshoot IR sensors, receivers, and circuit boards for precise temperature control.
Electrical & Wiring Fixes
Loose wiring or failing capacitors can cause short circuits and system failure. We repair contactors, transformers, and circuit boards, ensuring safe and efficient electrical connections.
Blower & Evaporator Coil Cleaning
Dust buildup on blower fans and evaporator coils restricts airflow. We deep-clean fins, fan motors, and coil surfaces using coil-safe cleaners and air pressure tools for better performance.
Smart Control Setup
Upgrade your mini-split with Wi-Fi smart controls. We install and configure smart thermostats, zoning systems, mobile app integrations, and voice assistant compatibility for energy savings.
Coil Cleaning
Dirty evaporator and condenser coils lower cooling efficiency. We remove debris, apply coil cleaners, and straighten fins to restore optimal heat transfer and prevent overworking your system.
Condensate Drain Maintenance
Clogged drain lines cause water leaks and mold buildup. We flush blockages, inspect drain pans, and test float switches to prevent water damage and keep humidity levels balanced.
Electrical & Component Inspections
We check relays, capacitors, transformers, and voltage loads to ensure your system operates safely. Our inspection prevents power surges, system failures, and costly electrical issues.

Signs Your Ductless AC Needs Repair – Don’t Ignore These Clues!
Not Cooling Efficiently
Weak airflow or uneven cooling can result from clogged filters, low refrigerant, a failing compressor, or blocked evaporator coils. We diagnose and restore proper heat exchange for peak efficiency.
Strange Noises
Grinding, buzzing, or clicking sounds indicate worn-out bearings, loose fan blades, electrical issues, or compressor malfunctions. Ignoring these can lead to costly breakdowns or system failure.
Leaking or Excessive Moisture
Water pooling near your unit suggests clogged condensate drains, frozen coils, or refrigerant leaks. These issues can cause humidity imbalances, system inefficiency, and potential mold growth.
Unresponsive Remote Control
A faulty IR sensor, loose wiring, or thermostat miscalibration can prevent your remote from communicating with the unit. We troubleshoot and replace circuit boards, receivers, and faulty sensors.
Higher Energy Bills
Spikes in energy costs signal low refrigerant levels, compressor strain, dirty coils, or inefficient cycling. We fine-tune your system, optimize SEER ratings, and restore energy-efficient operation.
Cooling You Can Trust
Types of Ductless AC We Repair – Reliable Service for Every System
Single-Zone Mini-Split Systems
Designed for individual rooms, these units rely on a single air handler and condenser. We diagnose compressor issues, refrigerant leaks, fan motor failures, and thermostat malfunctions.
Multi-Zone Ductless AC Systems
Multi-zone systems use multiple indoor units linked to one condenser. We fix faulty expansion valves, refrigerant imbalances, airflow restrictions, and zoning control board issues.
Ceiling Cassette Ductless Units
Installed within ceilings, these units require clean condensate pumps, balanced fan speeds, and proper refrigerant flow. HVAC Group repair drainage issues, sensor faults, and air circulation problems.
Wall-Mounted Ductless ACs
The most common ductless AC, these units need clean evaporator coils, precise airflow calibration, and functional remote sensors. We repair blower motor failures, refrigerant leaks, and electrical faults.
Floor-Mounted Ductless ACs
Ideal for low-wall installation, these systems require efficient heat exchange and unrestricted airflow. We troubleshoot fan motor malfunctions, clogged filters, faulty dampers, and sensor errors.

Frequently Asked Questions
How often should ductless AC be serviced?
How much does ductless AC maintenance cost?
Routine ductless AC maintenance typically costs between $150 to $300, depending on services like coil cleaning, filter replacement, refrigerant checks, and thermostat calibration.
What is the average life of a ductless AC?
The average mini-split lifespan is 15 years, but with regular filter cleaning, refrigerant management, and proper electrical upkeep, some systems can last up to 20+ years.
How much does it cost to replace a split AC compressor?
A new split AC compressor costs $600 to $1,500, including parts and labor. The price varies based on brand, refrigerant type, and BTU capacity. Professional installation ensures system longevity.
Why is my ductless AC not cooling properly?
Poor cooling could be due to low refrigerant levels, clogged filters, faulty blower fans, or a malfunctioning thermostat. A professional diagnosis can pinpoint the issue and restore efficiency.
Can I clean my ductless AC filters myself?
Yes! Washable air filters should be cleaned every 2-4 weeks to maintain airflow. However, deep cleaning of evaporator coils, blower fans, and condensate drains should be done by a professional.
Do ductless AC units require refrigerant refills?
Yes, but only if there’s a leak or improper charge. A technician will check refrigerant levels, inspect for leaks, and recharge the system as needed to maintain cooling efficiency.
What brands of ductless ACs do you service?
We repair and maintain all major brands, including Mitsubishi, Daikin, Fujitsu, LG, Panasonic, Gree, and more. Our technicians handle single-zone and multi-zone mini-split systems.
When should I replace my ductless AC instead of repairing it?
If your unit is over 15 years old, requires frequent repairs, or has a failed compressor, replacement may be more cost-effective. A new high-SEER unit can improve efficiency and lower energy bills.
