Josh also went above and beyond by polishing the exterior of the hvac unit so
That it now looks like new. I’m very pleased.“

“Geovany and the Power Fusion Team, Rock! Had a hiccup with our Ring Camera (which they originally installed 5+ years ago!), it was not syncing with the software. As all the Crews were out in the field, Geovany came out personally to assist! That’s phenomenal Customer Service, right there! After a lengthy chat with Ring operations, the issue was resolved in real time. We’d highly recommend their services, There are no other electrician's at their level of expertise or Customer Satisfaction!“

“Jan was absolutely fantastic. He was super nice and knowledgable. He fixed our AC quickly and advised on the correct course of action.“

“Mario Garcia was great!! Initially, I requested 2 bathroom faucets replaced due to one with low water pressure and the other constant dripping only to learn that the pipes were crystalized/calcified/scaled by my salt water softener. Mario later checked the water pressure in the house and the main and all were good. He then recommended and installed the FLOW-TECH device to neutralize the harshness of “City” water that would preserve my pipes and tankless water heater. My deepest gratitude to Mario for saving me thousands of dollars in the future with
re-piping my entire house!!!“

“Justin is a hero! He spent 3 hours servicing my entire system for $70! Justin is communicative, honest, knowledgeable and hard working. He identified a potential issue with my blower which ended up being the result of a previous bad service. They tried to oil sealed beating which doesn't work. Justin let me blow and clean the blower mirror assembly which made it run like new. He also measured and identified an off limit capacitor which I replace myself from Amazon for $10. Justin also cleaned up my AC outside unit and checked the caps there. My system is now checked, cleaned and running like new thanks to these guys. I highly recommend them. Just make sure you do your homework and take your time to understand if there are truly any potential issues that need fixing especially if your units are on the older side. I opted out of the coil cleaning service as it is too expensive and not worth in my opinion. All and all, great guy.“

“I had a great experience working with Andy and his team at L & O. From the start, they were extremely responsive and easy to communicate with. Andy took the time to really walk me through my HVAC system, explaining everything in a way that actually made sense, which I really appreciated.

Their team showed up on time, worked efficiently, and were very professional the entire process. What stood out the most was how reliable they were no runaround, no delays, just solid, honest work.

On top of that, their pricing was very fair compared to others I looked into, especially for the quality of service they provide. You can tell they care about their customers and take pride in what they do.

If you’re looking for an HVAC company that’s knowledgeable, affordable, and dependable, I definitely recommend Andy and the L & O team. I’ll be using them again in the future.“

“My old air conditioner was dying. I called Keith and he gave it CPR for over an hour but it didn’t make it!!!
Well, everything passes in due time and is replaced by a new generation!! Keith was able to get a new unit and install it by the next morning …
So the story goes on… after a week , I could not get the thermostat to work ( it died too) so consequently ….. no air and of course, the first heat wave had hit Simi! I called late afternoon and Keith and Ayden were there the next morning with a brand new thermostat!
