Authorised Mitsubishi Electric & Daikin Installers — Greater Sydney
Mitsubishi Electric & Daikin installers. Sized correctly, installed cleanly, backed by warranty.
REPAIR HVAC SERVICES is run by the people who show up on the job. We're hands-on, transparent, and extremely honest — we don't push unnecessary upgrades or replacements. We provide clear options and let you choose what's right for you.
We install premium Mitsubishi Electric and Daikin systems for homes and businesses — sized correctly, installed cleanly, and backed by manufacturer warranty. Here's exactly what's covered.
We attend your property, assess the space, and recommend the correctly sized system for your needs — not oversized, not undersized.
We supply and install Mitsubishi Electric or Daikin systems — indoor head unit, outdoor condenser, refrigerant piping, drain, and interconnecting cables.
We take pride in clean installs. All pipework is neatly run and covered, penetrations are sealed, and your home is left exactly as we found it.
Once installed, we commission and test the system on full load — verifying correct refrigerant charge, airflow, and electrical connections before we leave.
As authorised installers, your new system comes with the full Mitsubishi Electric or Daikin manufacturer warranty — giving you long-term peace of mind.
We walk you through how to operate your system, set temperatures correctly, and remain available after installation for any questions or follow-up.
We're authorised installers for two of the most trusted names in air conditioning. Both brands are known for reliability, efficiency, and long-term performance.
Mitsubishi Electric air conditioning systems are renowned for their quiet operation, energy efficiency, and advanced inverter technology. Their split systems and ducted units deliver precise temperature control — making them a top choice for both residential and commercial properties across Sydney. As authorised installers, REPAIR HVAC Services ensures every Mitsubishi Electric system is installed to manufacturer specification, protecting your warranty from day one.
Daikin is one of the world's largest air conditioning manufacturers, trusted by homeowners and businesses for decades. Their systems are built for Australian conditions — handling Sydney's humidity and summer heat with ease. Daikin's range covers everything from compact split systems to full ducted solutions, with exceptional reliability and energy star ratings. REPAIR HVAC Services are authorised Daikin installers, ensuring every unit is commissioned correctly and your warranty remains intact.
A standard single split system installation typically takes 3–5 hours. This includes mounting the indoor head unit, positioning the outdoor condenser, running refrigerant piping and drain lines, making electrical connections, and commissioning the system. More complex installations — such as multi-split systems or longer pipe runs — may take a full day. We'll give you a realistic timeframe when we quote.
Sizing depends on several factors — room dimensions, ceiling height, insulation, window area, and sun exposure. As a rough guide, a standard bedroom might need a 2–2.5kW unit, a medium living area 3.5–5kW, and a large open-plan space 6–9kW or more. Undersized units run constantly and never reach temperature; oversized units short-cycle and waste energy. We always assess the space before recommending a system to ensure you get the right size for your needs.
