R.M. Mechanical is factory-certified to install and service LG equipment for homeowners and commercial clients across Tampa Bay. Florida license CAC1820870.
LG is what we install when there is no good way to run ductwork. Additions, converted garages, Florida rooms, and older homes where the duct system cannot be extended.
LG's inverter-driven mini-splits modulate rather than cycling on and off, which suits Florida's humidity load well. A multi-zone system runs several indoor heads from one outdoor unit, so zoning a whole house does not mean an outdoor unit for every room.
These are the failures we are called out to most often on LG equipment in this climate, rather than a general list of things that can break.
Wall-mounted heads drain by gravity through a small line. If that line was pitched wrong when it went in, or it blocks up, the first thing you see is water running down the wall. Most of these calls are installation faults, not broken equipment.
Mini-split refrigerant connections are flare fittings made on site, not factory-brazed. A flare that was not cut and seated properly will weep refrigerant slowly for months. Slow capacity loss on a fairly new mini-split usually points here.
Mini-split filters sit behind the front panel and are easy to forget because they are not in a return grille. A blocked filter on an inverter system shows up as reduced output long before it shows up as an obvious fault.
LG multi-zone systems solve problems in both settings. In houses they condition additions and converted spaces without new ductwork. In commercial settings they let you cool a handful of offices independently without running a central system for a single occupied room after hours.
LG mini-split installs are permitted and inspected under license CAC1820870. That matters more here than on other brands. LG warranty terms generally require a certified installer, so an uninspected job by an uncertified fitter can void the coverage.
Yes, and most of it is. Most LG mini-splits we are called to were installed by someone else, and a fair number of the faults trace back to that installation rather than the equipment. Line set flares, drainage pitch and refrigerant charge are the first three things we check on a system we did not put in.
Yes, R.M. Mechanical is factory-certified to install and service LG equipment for residential and commercial customers, under Florida contractor license CAC1820870. That covers installation, diagnostics, and warranty work on Art Cool mini-splits, Multi F and Multi F MAX multi-zone, LGRED heat systems.
Most LG mini-split warranties require installation by a certified installer. Worth checking before you buy a unit online and hire someone to fit it. We are certified, and we register the equipment we install.
Indoor head drainage. Wall-mounted heads drain by gravity through a small line. If that line was pitched wrong when it went in, or it blocks up, the first thing you see is water running down the wall. Most of these calls are installation faults, not broken equipment.
Rule out the cheap causes before assuming the compressor is gone. Mini-split refrigerant connections are flare fittings made on site, not factory-brazed. A flare that was not cut and seated properly will weep refrigerant slowly for months. Slow capacity loss on a fairly new mini-split usually points here.
We service LG equipment throughout our coverage area, including:
Same-day service is usually available. We quote the diagnostic fee before we dispatch.
