HVAC reviews in Downey, California

The technician showed up right on schedule. They gave our system a thorough look, suggested some fixes and carried out the work all with a friendly demeanor. We're very happy with how everything went.

This company stepped up when they realized they'd left a permit issue open from years ago. After our city notified us of the problem, Mayra got on top of it right away, reopened the permit, paid the necessary fees, and scheduled an inspection to close it out quickly. I was impressed that they took ownership of their mistake and fixed it fast. It's not often you see a company own up to errors like this and make things right so promptly. That kind of service warrants recommendation - I wouldn't hesitate to send them my friends' business.

We bought a wall heater in February 2025 and were extremely satisfied with our choice of Southwest HVAC for the installation. Their upfront pricing was unbeatable, but what really impressed us was their integrity and dedication to customers. They consistently deliver on their promise of prompt support, always showing up when needed. A huge thanks goes out to Fabian for his excellent service.

This technician, Fabian, was outstanding. Extremely professional, honest, and knowledgeable. He quickly identified the issue and fixed it efficiently. His exceptional work ethic and customer service skills make him a valuable asset to your team. I highly recommend this company.

I recently hired Southwest HVAC for three mini split installations in my two-bedroom condo. My neighbors, who had a similar experience, raved about their service and convinced me to choose them. The prices were fair, and the work exceeded expectations - they seamlessly integrated the units into the walls and drywall, even painting over the lines. I also had an old gas heater removed and reworked to fit in. Overall, I'm thrilled with my new air conditioning setup. Their professionalism and attention to detail made a big difference. I'd highly recommend them for any HVAC needs.

I've relied on Southwest HVAC for my home's heating and cooling needs with consistently positive results. This visit from Eduardo stood out - he was courteous, informed, and methodical during the maintenance check. His professionalism gave me confidence that my unit is well taken care of.

They followed through on their promises with the maintenance visit after installing three mini-splitters and a package unit. The techs were knowledgeable, responsive, and arrived quickly.

Southwest HVAC is fantastic. They do a great job efficiently and professionally. The staff is incredibly friendly and competent. Communication is excellent - they call to schedule maintenance, which is included in the warranty, making it a great value.

Blown a fuse on the Nest thermostat by accidentally touching two wires - called in Fabian who fixed it efficiently and explained what went wrong.

Eduardo performed exceptionally well during my annual home inspection. His focus on safety is impressive, as he uncovered two critical concerns that were promptly addressed. The annual contract provides valuable reassurance at a reasonable cost – I'm glad I invested in it.

I've been a loyal customer of Southwest for nearly a decade and I have no doubts about their quality workmanship. They've installed and maintained both my main house HVAC system and mini split with impeccable care. The entire team, from the office staff to the on-site technicians, consistently demonstrate professionalism, courtesy, and attention to detail. Their commitment to excellence has earned them my highest recommendation. Special kudos to Edwin for delivering outstanding service during my recent visit.

Fabian's service for our split unit AC was top-notch. On time, courteous, and expertly done - a great experience overall. Highly recommend Southwest HVAC; they deliver high-quality work without hassle.

Southwest HVAC has served my AC unit for over a decade, delivering exceptional work from the start. Regular maintenance visits have consistently yielded great results. My system continues to perform admirably, maintaining a comfortable subarctic temperature within my home. Notably, I've always received the same technician, which suggests a high level of employee satisfaction and professionalism. The company's approach is evident in Fabian's friendly demeanor and reliability – he remembers key details about me and my family, making each visit feel like an old friend dropping by.

We had a fantastic experience with SW HVAC. Dillon was an excellent point of contact, explaining everything from start to finish and helping us choose the right unit for our space. The installation team were incredibly considerate and respectful of our property, leaving it tidy afterwards. As long-time customers, we'll continue to rely on them for all our heating and cooling needs.

They've been reliable over the past year, consistently delivering top-notch service. When our old heater finally gave up after 24 years, they stepped in and replaced it. Given my house's compact space from the late 1940s, they had to make some custom adjustments. The job took around 14 hours with three technicians working together - no extra cost for the complexity. I highly endorse this company.

I bought my AC and heating unit from Southwest eight years ago and had a great experience with them back then. Recently, they helped me out when I needed assistance after my balcony repair work was done. They took it away, stored it for a few days while I got the repairs done, gave it a tune-up, and brought it back to me with the same excellent customer service I'd had before. Fabian was top-notch on-site; their in-house staff were also very helpful and pleasant. Overall, I highly recommend Southwest for all your home services needs.

I had a fantastic experience with Southwest HVAC. From start to finish, everything went smoothly. The initial diagnostic was done by Erick, who took the time to clearly explain the issues with my system. Luis followed up promptly with a quote for the work and even offered to install a portable AC unit on the same day to keep me cool while I waited.

The next day, I met Alex and Elmer, who worked tirelessly in scorching heat. By evening, they had installed a brand new system - what a relief! The team was meticulous, leaving everything spotless and following instructions for pipe connections.

But what really impressed me was the personal touch. Luis surprised my wife on her birthday with thoughtful gifts, including a personalized card from the entire office staff. He even brought pizza for lunch, which was incredibly sweet of him. It's clear that this team truly cares about their customers.

Overall, Southwest HVAC exceeded my expectations in every way. I have no hesitation recommending them to anyone - they'll deliver top-notch service and genuine kindness.

I hired Southwest for four HVAC maintenance visits and they've consistently delivered reliable service. They conducted a thorough inspection and cleaned my system. The only reason I don't give them five stars is that their pricing has increased to over $100 per visit, which is higher than other companies' monthly fees. Still, it's the more affordable option available.

"Top-notch HVAC work here. The crew was ultra-professional, communicated clearly and confidently, and delivered excellent customer care throughout. Post-installation follow-up was comprehensive and genuinely concerned. I highly endorse this local outfit - would definitely use them again."

I've had a great experience with Southwest HVAC from start to finish. From initial contact with Mayra Villa, who scheduled the appointment, to the technician Eduardo's visit, the professionalism has been top-notch. Eduardo explained every aspect of the work and parts needed to get my furnace fixed, including replacing a specific part required for the diagnosis. He promptly drove to the supply center to complete the job efficiently. I'd highly recommend this company if you need reliable quality service for your home.

Southwest HVAC did a great job on my AC service. The technician who came out, Eduardo, was extremely polite and efficient. He got the problem sorted out quickly and left me feeling satisfied. I'm glad I chose this company and would definitely hire them again; they've earned a customer for life!
