HVAC Installation in Los Angeles
A Century of Service, One Team for Plumbing & HVAC
Red Lilly Plumbing has served Los Angeles since 1924, and for four generations we’ve handled both plumbing and HVAC under one roof. That matters on an installation project. When a new furnace needs a gas line connection, or a heat pump installation involves condensate drainage, our team handles both without coordinating a second trade. One licensed crew, one point of contact, less disruption to your property.
How We Size & Install Your System
Before recommending any equipment, we perform a load calculation using modern tools to determine the right system size for your property. An undersized system won’t keep up on a hot July afternoon in the San Fernando Valley. An oversized one can short-cycle, wear out faster, and leave humidity uncontrolled. Proper sizing is the foundation of every installation we do.
Our installation services cover heaters, central air conditioners, heat pumps, ductless mini-splits, and air duct repair and installation. We tailor recommendations to the Los Angeles climate: hot, dry summers and mild, wet winters mean a heat pump often handles both seasons from a single system more efficiently than separate heating and cooling units.

Choosing the Right System for Your Los Angeles Property
Many homes in Los Angeles were built before central air conditioning was standard. If your home has existing ductwork in good condition, a central air conditioning system delivers even, consistent cooling throughout the space. If the ducts are undersized, leaking, or absent, installing or repairing them is part of the project, and we handle that work directly.
- Ductless Mini-Split Systems
For homes without ductwork, ductless mini-split systems offer flexible, room-by-room comfort without the cost of adding ducts. They’re also well-suited to additions, garages, and converted spaces where running new ductwork isn’t practical. - Heat Pumps
Heat pumps move heat rather than generate it, which makes them highly efficient in Los Angeles’s mild winter climate. A single system covers both heating and cooling, and current LADWP rebate programs make qualifying heat pump equipment worth evaluating based on cost as well as performance. - Packaged Systems
For properties with limited indoor mechanical space, packaged systems combine heating and cooling components into one outdoor unit. These are common in commercial settings and smaller residential properties where a split system isn’t practical.
Why Los Angeles Property Owners Choose Red Lilly Plumbing
Our technicians are licensed, bonded, and insured, and they participate in weekly OSHA training so installation work meets current safety and code requirements. We also have bilingual staff, which means communication stays clear throughout the project regardless of your preferred language.
We don’t sell equipment first and ask questions later. Every project starts with a transparent conversation about your property, your comfort goals, and your budget. Free, honest estimates are standard, and we take the time to explain what we’re recommending and why. Our work uses modern, eco-friendly equipment and sustainable practices that reflect both our values and the direction Los Angeles utilities are moving.

“When I bought my home the previous owners left out that the plumbing sucked! From the look of the house is was very nice on the outside, fresh paint, new kitchen counter tops and new flooring. Little did I know that 1 year after I purchased the home I would be hiring a plumber to fix the whole kitchen plumbing. He said the previous guys literally did quick fixes and nothing was by code. Red Lilly took a look at all the plumbing in my house and made everything work and up to code for a pretty good price. Thanks Red Lilly!”Sorenerca
