Heating & Air Conditioning / HVAC near South El Monte

“Our heater required some maintenance and we got a new furnace installed as well. The team was not pre-emptive or pushy in explaining our choices. The installation was relatively easy and fast. The new system is excellent and it heats the house and makes it comfortable.“

“Alex was very helpful and communicative. He explained what’s was going on and was very pleasant.“

“We recently had our ducts cleaned, and William was great to work with. He helped set everything up quickly, worked around our schedule, and made sure it got done ASAP since we had just moved into the space.

He took the time to explain the process in a way that was easy to understand, and you can tell he really knows what he’s doing. Everything was handled smoothly and professionally, and we noticed a difference right away. Definitely recommend!“

“Air Comfort Experts ultimately delivered on a difficult, intermittent manufacturer-related HVAC issue, and I appreciate their commitment to resolving it.

ACE installed our rooftop Trane unit back in April, but unfortunately shortly afterward an intermittent problem with the unit began. Because it was inconsistent, it took time to diagnose and couldn’t really be reproduced during visits. Over roughly nine months, their team worked through multiple troubleshooting steps and escalated each step of the way appropriately, ultimately needing to coordinate directly with Trane where they determined the problem to be a manufacturer-related issue with the unit.

A few weeks ago, the unit's blower motor was replaced under warranty, and since then the system has been operating exactly as it should, with immediate fan starts on every call. While follow-up sometimes required persistence, they stood behind their work, completed a challenging rooftop install and repair, and saw the job through to a successful resolution.“

“Randy was very efficient, explained all the information that I would need to know and was very pleasant.“

“A/C was not cooling as it should I found Frank at Hybrid A/C and heating in Pico Rivera.
He listened to my concerns and set me up with an appt that afternoon, his associate showed up promptly at 1pm as scheduled and diagnosed the problem.
After discussing my options, Frank showed up shortly thereafter and fixed the issue.
If your looking for a good, reliable HVAC Tec that knows his business and will explain things clearly Frank at Hybrid A/C is your guy, quick and efficient, a true professional, thanks again Frank ?“

“David, the technician assigned to my service visit, was excellent and provided detailed information and instructions regarding maintenance and upkeep of my HVAC system. He provided before and after photos. Both he and his trainee, Daniel, were professional and personable.“

“Six years ago we learned that a local company, Comfort Climate Control, installed and maintained the Trane HVAC systems. We believe that we made the right decision to work with them for our HVAC needs. They continue to provide excellent customer service and professional, knowledgeable, and respectful field staff. You can count on Comfort Climate Control for a customer satisfaction experience!“

“We've been Air-Tro customers for over 20 years and the HVAC system they installed for us in 2005 is still going strong because of their excellent care and maintenance. This spring, Paul expertly diagnosed and fixed a leaky part, which should keep our unit running for the rest of its life. We are so grateful to Paul and the whole Air-Tro crew!“

“TL:DR - great customer service, friendly, and welcoming!I was looking for someone to fill my co2 tank and I feel lucky to have found Gilmore Liquid Air. It's close to me and I didn't have to swap tanks-- I could get my own canister filled by them. I definitely feel like a valued customer and welcomed when chatting with the employees here. More importantly, i learned so much. I was greeted by two gentlemen, 1 older and 1 younger. The young one looks like he can bench a cow. If I was to guess, the older gentleman was named Tom because he looks like a Tom. I came on 2 separate occasions. Both times I was greeted and welcomed. The first time I came I brought a used co2 canister. I've already read some stuff about co2 but there's so many components involved i figured I'd just wing it and see how it would go. Both of the gentlemen spoke with me and answered all my questions. They didn't try to push to sell anything instead, they taught me some stuff and recommended to do some things. So in my case, I wanted to inject co2 into an aquarium to help grow my plants. This steel canister I brought is prone to rusting and heavy. so they just mentioned it and mentioned that they can fill this one OR get an aluminum one which is much lighter. More importantly I had an unusual fitting "CGA 580" and he mentioned that the normal fitting is the "CGA 320" so now I was in over my head. Instead of going home and doing a bunch of research, I just asked them what would they do? They recommended the easy route which was to buy a new one on Amazon-- which I did. Easier, more cost efficient, and saved me a bunch of timeMy second visit was to bring the aluminum tank and fill it with co2. During this visit again I was greeted so warmly-- it really reinforced the family business vibe. They informed me that they usually fill tanks in the morning. So I dropped off my tank and came back the next day. Tank filled and they educated me on how to use the tank, rest time, proper handling, etc. I think the most important piece of information I got was to use the tank upright-- I had no idea that co2 was put in as a liquid format! I'm really happy that I was to find Gilmore Liquid Air. I feel I can trust them in their service and pricing. I'm excited to go back when my co2 runs out. Woo hoo! I'm a fan. Go Gilmore Liquid Air! More- I guess people usually come here for welding stuff. So I'm an oddball for wanting co2 for a planted tank. Tom gave me the rundown of all the supplies so I included them in the description. They also do other gases too!“

“Brandon is a great technician and went above and beyond helping us with a rodent problem he discovered while servicing our unit“

“We had them upgrade our intake to a larger size. They had it done super fast and they were clean and lovely guys. They even showed love to our little dogs.“

“Contacted Aire Serve via email on a Wednesday, they responded the next morning and had a tech available the same day. The tech (Bryan) was very professional. No hard sell, just advice and options. He did a thorough assessment, explained to me his recommendations, and gave me some tips for how I could improve the AC’s function separate from the unit itself. I am not sure what steps we will take, but going forward, I will use this company for any future AC/heating needs. I was pleasantly surprised at such high quality customer service in 2026! Highly recommend.“

“Thank you ray jr for job well done, jr came out to do preventive maintenance on our central air and found a part that was not working as it should and was able to replace it the same day this should hopefully extend the life of our system. THX JR“
