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.

“Red Lilly is so great!! Joey was the plumber that came and he was so helpful, competent and personable. My shower drain has been driving me crazy and my building won't fix it as they say plumbing it's the tenant's responsibility. So I had to call my own plumber and thank goodness I called Red Lilly - they took care if it quickly and affordably. They were also on time for the appointment which was a relief as I'm always so busy. I'd highly recommend them!”Chenoa M.

“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

“I cannot say enough about the owner and crew of Red Lilly. We had a sewer issue with a newer line that ended up becoming a major sewer redo for out entire system. Giovanni and Harry provided an excellent diagnosis and very creative rerouting of our entire system. They worked tirelessly for two weeks, rerouting the piping and putting in a sewer ejector pump to alleviate the problem. Hats off to the crew (Chris, Carlos, Juan, Edwin, Jose, and Hugo) who left the yards looking good, replanting plants and replacing pavers and gravel. More importantly, they were cheerful under long trying days. We also appreciated that only two times they had to cut the water usage for a couple of hours while they connected the sewer lines under the house. In addition, they installed a liner in the sewer pipe to the street to combat the tree roots that were destroying the 100-year-old pipe. Thanks so much for the top notch work, great communication, and follow up!!!”Peggy T.

“I notice a bad smell coming from under my house. I went out there and looked around with a flash light and found a big puddle of water under my house. I called red Lilly and they send Carlos. He crawled under the house he determined that there was a drain pipe broken. He took pictures and showed me what the problem was. Gave me a estimate to replace it. Which it was more then fair!! Took about 3 hours showed me some before and after pictures I paid him and he was on his way. No time wasted!! Told me what the problem was how to fix it and how much it would cost me.”Mr. S
