Is your mini-split blowing warm air, dripping water, or flashing an error code? Omega Tech Service repairs and maintains ductless mini-split systems across San Diego County, from single-zone wall units to multi-zone systems with ceiling cassettes and ducted air handlers. We are a CA C-20 licensed HVAC contractor (#1149953), and our technicians work on mini-splits every day.

We find refrigerant leaks at flare connections, the line set, or a coil, repair them, pressure-test, evacuate, and recharge to the manufacturer's specification. We also clear blocked drain lines, replace failed condensate pumps, and clean coils that overflow the drain pan.
We read the system's diagnostics and test sensors and wiring before replacing any part. We repair control boards, indoor and outdoor fan motors, compressor start failures, communication errors between indoor and outdoor units, and remote or wall controller problems.
Dust, pet hair, and kitchen grease build up on the indoor coil and blower wheel faster than most people expect. Regular maintenance keeps efficiency up, prevents water leaks, and catches small problems before they become expensive.
A maintenance visit includes:
How often? We recommend at least once a year, and twice a year for homes near the coast, households with pets, or units in kitchens and bedrooms that run most of the day. Salt air near the ocean is especially hard on outdoor coils (read more: Common Ductless Mini-Split Problems Caused by San Diego’s Salt Air). Ask about our annual maintenance plan.
We repair and maintain all major mini-split brands, including Mitsubishi Electric, LG, Bryant, Carrier, Daikin, Fujitsu, Samsung, Gree, and others. Omega Air is a Mitsubishi Electric Diamond Contractor.
Most mini-split problems are worth repairing. If your system is older, uses R-22 refrigerant, or needs a compressor, we’ll give you both options honestly: the cost to repair versus the cost to replace, including any available rebates.
The most common causes are a dirty filter or coil, low refrigerant from a leak, or an outdoor unit that isn't running. Clean the filters first; if that doesn't help, it needs a diagnostic.
Usually a clogged condensate drain or a very dirty coil. Turn the unit off to prevent wall damage and call for service.
Yes, you can wash the filters yourself every few weeks. Deep cleaning the coil and blower wheel requires taking the unit apart and should be done by a technician.
Yes, single-zone and multi-zone systems, including ceiling cassettes, floor consoles, and ducted air handlers.
