Robert from GAMA services is the best!!! They came to my house & fixed the air condition and I was extremely happy with their service. I highly recommend "GAMA" to anyone they definitely take care of their clients & work with your budget. read more

They were fast and very reasonable on price. Very happy with the service. I definitely recommend.

Our store AC started acting up, sometimes blow cold air normally and other time was not doing anything! So we Called GAMA and Eddy showed up in no time and diagnosed and fixed the issue and told us what to do so this won't happen again! I recommend this company for all of your air-conditioning and heating needs! Thank you read more

Great family-owned company they don't rip you off they fix only what you need fixed I highly recommend them for any of your AC needs we are so happy with their work and recommend them to anyone they will be our only AC company from now on read more

Robert your technician did a great job. He texted prior to arriving. He talked to me first to see what issues the unit was having. He thoroughly checked the coils/compressor,capacitor, and evap coils/unit blower. He was polite and honest in his evaluation of our system. Thank you for providing good honest service. Just to add the owner called me the day before to explain the service charge. I was ok with that because it was a total system check from a honest company that's not trying to upsell me on a new unit. Our system is old but working fine. Check your systems before any problems arise and you won't get sticker shock. Kinda like changing the oil in your car. If you don't do when your supposed to your buying a new engine. Thanks GAMMA Bob A read more

Roberto worked on unplugging my kitchen sink drain. Awesome job as usual. His crew worked on my AC unit these past few years, and have done an outstanding job as well. I highly recommend this company. read more

I first found Gama through the LADWP tube up program and found them to be prompt, reliable, fair priced, and trustworthy. They are now my go-to HVAC company. From the receptionist who worked with me to make an appointment happen very quickly to the tech who has since returned so I feel a consistency of service as well. Highly recommend! read more

Highly recommend this company we had heating and air installed very professional and cleaned up every day. Very hard workers and knowledgeable in installation. We are very happy with their work. read more

I've used Gamma for years. They have fixed the heating, fixed the AC drip pan that was incorrectly installed by someone else, replaced the water heater, and just had them out to replace the disposer in the kitchen. Everything they have done has been top notch with no issue or fuss. Fair prices. Good work. Clean workers. What's not to like? read more

Charges $125 just for diagnosing and didn't explain charges ahead of time until they show up at your door and then you are stuck with rude attitude and hurry they need to go mentally. On top of that, the quote is outrageously higher than other companies not to mention they will not fix electrical problems. Do not recommend. Same day in the afternoon. Another technician from another company came out and repaired both units for a fraction of the price. A fraction of the price. Literally! No insurance was involved. Wrong diagnoses and incompetence. read more

I tried to get service from this company. He charges $150 plus parts if it's something simple like changing the fuses. Higher than most, but he said he could come out same day. Cool. There was a misunderstanding about payment, and he goes bipolar on me. I told him never mind. He must believe he is the only AC guy in town. Poor customer service. read more

Had my LADWP AC Tune Up appointment rescheduled twice but didn't mind since it was a going to be a free service. Roberto and Eric arrived and were professional, informative, and courteous. They went inside and even inspected one of my vents because I mentioned hearing a rattling sound. Roberto reached in and pulled out some construction debris - problem solved. I would highly consider using them for any future AC needs. read more

The best AC/Heating company in the area; responsive, good communication, and down to business. Roberto and his crew are great, very experienced so they know what they are doing and reasonable prices. read more

*********************************Do NOT use Gama************************************ VERY UNRELIABLE & UNPROFESSIONAL!!!!! I manage many properties and needed a new A/C vendor. Definitely NOT recommending this place! Try calling them, they NEVER answer their phone. Don't waste your time with these guys... read more

Gama Central are true professionals. They came out to do a LADWP air conditioner service and were here for about 1 1/2 hours. Checked everything out, cleaned the a/c unit outside and ran diagnostics on the entire system. Then they installed a Nest thermostat and showed me how to use all the features it provides. Professional, knowledgeable and friendly folks who know what they're doing and are happy to be of service. In addition they found a heating issue that I paid another company to fix but was done incorrectly. They fixed it at no additional charge. Would recommend these guys to anyone looking for quality, competent and friendly service. read more

I used Gama for LADWP's free AC service and NEST thermostat program. If you're a DWP customer, take advantage of this! I called John at Gama, who got back to me promptly to schedule the service. They came out quickly, even in the heat of August, serviced my AC including new filters, gave me a free Nest thermostat and filled out all the necessary paperwork. I will definitely use Gama for future HVAC needs. I'm very happy! read more

I made an appointment because I really needed my AC fixed and they never showed. Never got a call back or any information to reschedule, extremely unprofessional. read more

Called at 9am to ask for service as my A/C isnt working. Roberto (owner) came out and fixed it by 3pm! He was very knowledgeable, polite and honest! I will use Gamma again and recommend this company to anyone who requires A/C repairs or service! 5 STARS! read more

Roberto and his staff are very professional and honest. I called for a problem with the AC unit and Roberto came the same day. He did a temporary fix and would not take money until he returns to diagnose the issue more accurately. As promised, his installers showed up and fixed the issue. They were also looking at the general condition of the AC unit without being asked to do so. The price paid was the same price quoted over the phone. Awesome service! read more

Gamma installed our system. I was satisfied with his service until now. My 84 year old mother called him to repair the air conditioning which was blowing very warm air. She waited all day and no one ever showed up or called. No one returned her messages. We waited an entire HOT holiday weekend. She had to call him the following Tuesday to schedule another appointment. No one showed AGAIN. He did not call or respond to my many calls or texts. I cannot believe that he would be so incredibly unprofessional. We will no longer use this company. read more

The people here are honest and fair. They do great work. I needed a new plumbing line installed in my house in Downey and they were able to replace it with a new one at a great price. Additionally any time my plumbing would get clogged they would be at my house in a couple of hours to fix the issue. Moreover, I dislike dealing with construction people because it feels like they're trying to swindle me. This isn't the case here with Mr. Gamma. read more

Had a great experience with Omar from Gama Central. He came out to give us A/C Service on our old Kenmore Central Air system through the LADWP Optimization Program. Had the old girl cooling down our house on a hot June Day. Wife is happy and Im happy. Thanks Omar. read more

Absolutely none better in the entire city of Los Angeles I trust this company Dann read more

Be advised. Gama won't service your ac unit through the LADWP program if your house is older than the year 2000

Love Gama Central Heating and Air. When I have a problem Robert sends someone out immediately. They are clean, courteous, professional and knowledgeable. Call them and you will be very glad you did. This group is as good as it gets. read more

Received free A/C tune up and Nest thermostat installation courtesy of LADWP program. Can't complain about that. The guys were pleasant and professional until both asked to use my bathroom. This is just bad form for installers but I guess I seemed cool. But really I'm not cool about strangers alone in my bathroom. Had a technical issue that I emailed about. First email was ignored but the 2nd one where I threatened the yelp bomb was responded to and a follow up visit was provided. I felt bad because shortly after they arrived I answered my own question online. But they didn't know either and hopefully all the techs now know moving forward. (The answer is: Nest won't let you run the fan on your central air without activating the thermostat. The work-around is to set the temp such that the ac/heat won't come on when you just want to run the fan. ) read more

Gamma Central is a professional and trust worthy company that has done several jobs for us. Their prices are very competitive and they have always helped to find the best solution for our projects. They warranty their products and services and have been great to manage their time to be available on urgent matters. read more

Gama does incredible work and is punctual, trustworthy and reasonably priced. Robert is excellent and consistently provides excellent care to his clients. I can't recommend them strongly enough! read more

Please be wary of this company! I was just quoted over $900 for a routine maintenance and minor repair and ended up paying $125 for the service call - all exorbitant amounts. Shop around as I should have - I am now finding well regarded companies are charging $45-65 for the service call and less than $150 for the maintenance! Buyer Beware!! read more

Very reliable, efficient and knowledgeable. Highly recommend!

Robert is a lifesaver, literally. Our AC unit stopped working during the heatwave days and requested service from another provider. This other provider came back with a crazy priced quote to replace a vital part in the unit he thought was the problem. Our AC unit being fairy new, we contacted Robert who found the problem in the fuse! For fracture of the previous quite, he was able to fix it immediately. Honest & reliable. read more

Thank God for Gamma, we came back home from two weeks vacation with a teething baby with high fever to a broken AC! I called over 20 companies to find anyone to come same day and was not successful. I called Gamma and Robert picked up the call right away and when I explained to him the situation, he said he will be there within the hour! He came on time, gave us a diagnosis, had all the parts with him in the truck, and fixed the AC in no time! There is no words to describe how thankful I am, I didn't want to take my sick baby out and it was impossible to stay in with a feverish baby in a 90 degrees home. Thank you Robert, from the heart! God bless you!! read more

Ac wasn't working, Robert quickly fixed it. We had a plumbing problem garage disposal needed to be replaced and corrosion in the pipes, Rob fixed it. What I can say Robert is professional and courteous. We will always call his company if we need plumbing or ac work. read more

Great job to Roberto and son they came quick to my house after they did a check up in less than a hour my AC was back in action!!! I highly recommend Gamma!!!! read more

These guys installed a new A/C unit in my parents home. The workers were very professional and overall nice guys. My dad gave them a little bit of a hard time in the beginning, and they kept their cool and were great. Great business, and good work done by Gamma. read more

I really had to post a review to let people know that Gama is just excellent! I have deal with numerous companies and Gama is by far the most knowledgeable and courteous i have ever dealt with. Had 2 big problems with my heating/AC unit and Robert promptly send somebody over. My place is in VENICE BEACH and they were right there!! The figured out right away what was wrong-managed to get the replacement parts in record time and even offered to install over the weekend. And all this at a very reasonable price. TRUST ME Do not bother looking elsewhere read more

Robert is a heating and air conditioning master! I've used their services many times over the years. They have always come to my rescue. The technicians are all very good and knowledgable. There is no problem they can't figure out. They're great at solving the issue masterfully and fast. Thank you guys! You're the best. read more

Great AC company. I use them for all my stores and my home. Never had a problem and the prices are very fair.

Gamma came to the rescue. It's been 90+ this past week, so I'm sure all AC service companies are super busy. Roberto came same day and tested, diagnosed, and replaced the faulty capacitor. Well worth the price for professional service! read more

GAMA did an excellent job evaluating my air conditioning units and servicing them with the DWP maintenance program (with no cost to me). But especially I want to give credit to Stephen Galvan who came out afterwards to give me advice on replacing my old unit. He was thorough and honest and essentially said not to spend the money now as it was working well enough. What a refreshing experience for me not to be sold something unnecessary. read more
