HVAC reviews in Signal Hill, California

Both the scheduler and the technician were great. Very helpful and communicative. Tom, the technician, explained not only what he was doing but also why. Great service.

These guys were great, highly recommend. They removed and replaced our HVAC system and all duct work and we couldn't be happier. Jason was the best onsite and so was the whole team and office staff.

Tom did an excellent job diagnosing my forced air heating unit issues and made the necessary repairs. Very knowledgeable and kind!! I highly recommend his company!!

Excellent service : AAA Calvert communication with the Dispatcher was excellent and Tom arrived on schedule and proceeded to take care of our furnace and thermostat issues in a courteous, patient and professional manner. Very reasonable cost for time and work done.
Thank you,

The team did a fantastic job today installing outlets in my garage/workspace. They were on time, knowledgeable, polite and communicated throughout with updates - providing solutions for any challenges that came up. AAA Calvert is now my go to electrician.

Antonio and his assistant were fantastic. The problem was diagnosed and quickly located and corrected. Tom Sullivan Senior wired this house. T.J. and his crew, led by Tom Garner replaced the Furnace and AC in 2019. AAA has serviced my church Community Grace Brethren Church for many years replacing roof top AC at the church as well as general maintenance. Both commercial and residential service has been exemplary. I would highly recommend AAA / Calvert.

AAA Calvert provided excellent service from beginning to end. It was easy to schedule service, they communicated well before the appointment, and the technician was friendly, professional, and competent. I will use them again.

It takes awhile to get an appointment, but I can say that this was an excellent visit. The tech was on time, well presented, communicated clearly, and was pleasant to deal with. He fixed my small problem, I am hoping that they can help me with our bigger estimate for major work as well.
Antonio was great and even my dog liked him!

Extremely pleased with the service and follow up service calls. Repairs to my air conditioner were done by a courteous, knowledgeable professional. Care taken for my floors. And excellent clean up offer.
Jason one of the owners did the follow up calls to assure the repairs and unit were running properly.
I highly recommend.

We decided to have 2 14-50 receptacles installed for EV car charging. We have 1 EV now, and thought we'd do 2 receptacles to be ready for the future. (We had a subpanel installed a while back in the garage when our solar panels were installed, for doing EV receptacles in the future.)

The electrician and apprentice were on-time and did very professional work. Everything was clean and they were careful not to have the wires stressed. Tested to see if the EV like them. Very happy with the work.

I have been using AAA Calvert for maybe 10 years. Tom was my first technician and later it was Jason. I have used them from for everything from standard maintenance and repairs to a complete unit replacement. They are always responsive, friendly and through. And their prices are very reasonable. It is always been a pleasure working with them and I recommend them to anyone needing HVAC care.

AAA Calvert was recommended by several people. The technician was very pleasant and answered all my questions. I will be using them for my HVAC needs in the future.
And today 2/18/26, AAACalvert put in my new HVAC. A crane was needed to change out the unit on my roof. The operator was very skillful as he had to go between 2 tall trees way up to the roof.
All the AAA guys were so friendly and introduced themselves to me. I am very pleased with my new HVAC and the expert service from AAA Calvert!

I really appreciate Jason working after hours to make sure he could get my thermostat working before the weekend. I thought wires had been chewed through by rodents, but he was able to determine that the thermostat itself had simply died. He gave me options for a new unit, clearly letting me know different price points and was able to get everything up & running quickly. My dog decided to supervise and he was very sweet with her.
I am very happy with my overall experience with AAA and will absolutely recommend them to anyone with electrical & HVAC issues.

I highly recommend AAA Calvert. Jason came to diagnose our heater because it wasn’t working and was able to repair it and save us thousands of dollars. From talking to the office and dealing with the technician, they were respectful of my home, worked efficiently, and made sure everything was running perfectly before leaving. I really appreciated their honesty and fair pricing no upselling. I will definitely be using their services from now.

Mario provides excellent 5-star service.

Long Beach Heating & Air Conditioning, Inc. is top-notch. I had a massive unit on an ancient house that needed replacing with barely any space for the crane. No fuss. They made necessary tweaks and got the job done without drama. The team is friendly and consistently courteous.

The technician visited my home to assess my HVAC system and offered suggestions for maintenance and installation of an air conditioning "cover". The service visit went smoothly, with no issues found with the heater. However, the A/C unit was serviced, the cover installed, and new registers placed. This simple addition made a noticeable difference in noise level - it's incredibly quiet now. Additionally, the new register placement ensures better airflow throughout the living room, making it feel more comfortable.

I've had my home serviced by this company for over two decades. The technician who helped me was exceptional - very knowledgeable and helpful. Each time I schedule a check-up, all of the employees have consistently demonstrated professionalism, promptness, and genuine care.

We've struggled with a finicky heating and air system in our home, constantly switching between service companies that failed to deliver on reliability. The unit's installation was riddled with problems from the start. After months of frustration, I stumbled upon Long Beach Heating and Air Conditioning and they've finally gotten both units working smoothly and consistently.

I'm thoroughly impressed with their service and would wholeheartedly recommend them to anyone in need of reliable heating and air solutions - current or future customers alike.

I recently had a new HVAC system installed by Chris, replacing my old 30-year unit. The result is nothing short of remarkable - the second floor is now cool for the first time in its history! Crystal regularly checks in to schedule maintenance calls and Abel's recent visit was spot on. Both are top-notch professionals. What impressed me most is Long Beach Heating & Air's commitment to customer satisfaction, going above and beyond my expectations. They truly deliver exceptional service - I wholeheartedly endorse them.

I'd been dealing with my heating system locking out randomly for an extended period, despite multiple attempts by three different companies to diagnose the issue. The representative assured me that her senior technician would send someone over to help. When Mario arrived, he quickly got to work and identified the problem - excessive 90-degree elbows in the exhaust system were trapping air and causing the heater to malfunction. He explained everything clearly, even taking photos of the installation. I was impressed with his professionalism and expertise.
