"My old HVAC system finally died, and in the middle of summer. I sent a request for quotes on Yelp and Lee's HVAC immediately responded and said they can send a tech the following day. They were super responsive and even followed up a couple of times when I forgot to respond."

Every room finally gets the airflow it was designed for — no more starved bedrooms.
Lower Energy Bills
Right-sized ductwork lets your HVAC run at peak efficiency instead of fighting restriction.

★ Real Reviews, Real Clients
225+ five-star reviews from Southern California homeowners.
"With summer approaching, we decided to conduct diagnostics on our HVAC units (rental and home) to ensure they were in good working order. Consequently, we contacted several vendors for assessments. The first two provided repair and cleaning estimates that seemed unreasonably high. We then reached out to Lee's HVAC, and Edaan conducted a thorough inspection of both units."
"We considered several quotes before deciding to go with Lee..out of everyone..he personally saw and gave his best price (worked with our budget and able to accommodate our requests)..his team is very responsive and good quality service..highly recommend using this company for your AC needs!"
"Lee & his team provided exceptional service! It was time to replace our old unit with a new one and I'm really happy with their work. They exceeded my expectations! Now my AC is working better than ever. I highly recommend this company."
"We just replaced our two old condensers with Lee's HVAC. Lee was great to communicate with, didn't try to upsell us on anything, and we felt he was very honest throughout the whole process. His pricing was great compared to all the other quotes that we received. His install team was professional, neat, and did a seamless swap. Lee recommended our new slimline high efficiency condensers and it's like night and day."
"My AC unit went out on the first day of a heat wave, naturally! Encino was 110 degrees. I called Lee's HVAC based on the reviews, and Lee personally answered the phone at 7 AM (well before business hours). He said they were nearby to Encino and had someone over within the hour. They diagnosed the issue and recommended a new 4 ton unit. A crane was needed to lift the unit onto my roof and the system is installed and working perfectly. You can tell it's a family-owned business by the way they treat you."
