"I’ve had the pleasure of working with Bill and Cool Air Technologies on several occasions and they never disappoint. They’ve done a HVAC replacement as well as an entirely new HVAC system install with impeccable results. They were professional and communicative; answering all my questions and working through any issues promptly. I will look nowhere else for my HVAC needs and highly recommend them to anyone considering their services."

"We needed our 16-year-old HVAC unit replaced, so I narrowed my Angie's List search down to seven Heating & Air Conditioning companies. The ones I chose all had an "A" rating with good reviews. Of those companies, two of them never returned my call, and one didn't work in Los Angeles (it's in Burbank but doesn't work in LA--go figure!). When I called Air-Tech, Heather, the Administrative Assistant, answered the phone--very friendly--and scheduled an appointment. Alex Fish was the Comfort Specialist that came to our home. He was on time, and called me on the road to let me know exactly when he'd arrive. Alex is very knowledgeable; studied every room, looked in the attic where our furnace is located, and examined our condenser and its power supply. Then we sat down and he showed us an illustrated booklet of a house that describes just how an HVAC unit works in a typical home. He walked us through the different systems and gave my wife and me options. He called the office to see if we qualified for an LADWP rebate and a Lennox rebate. We did. None of the other companies we'd seen were this thorough. Before he left, he had written out a detailed proposal including model numbers, what they do, the all-new gas piping, and drain and refrigeration line specifics, etc. Alex was the only person we had seen that wrote a complete proposal before he left the premises. A few days later, I called Alex with additional questions, and he talked to me for 20 minutes answering every question and concern I had. The job took a week to complete, and Carlos and his team covered the work area each day, were very professional and cleaned up at the end of the day, like they had never been there. Many of the technicians have been with Air-Tech for years. To me, that really says something about the company. My wife and I decided to go the permit route. Air-Tech pulled the permits, scheduled the duct testing (we passed), and Heather informed me of what was required with respect to smoke detectors, carbon monoxide detectors and their proximity to any ceiling fans in our house. Because of her heads-up and the outstanding workmanship of the Air-Tech team, final inspection was a breeze. Two techs even came out to double-check everything before the inspector arrived. I can't say enough about Air-Tech. A company that is honest, professional, and does excellent work. For any heating or air conditioning needs, Air-Tech cannot be beat."

"This was absolutely the best service I could have imagined. My vents went from filthy to spotlessly clean. I feel as if I can breath again. The value for the services provides was excellent. The technician, Elie, was fantastic. He was so service oriented and treated my wife and I like his own family. He worked with us on pricing so it was affordable and he gave us a ten year "club membership" for only $999.00 which gives us ten years of maintenance, twice a year for the next ten years to keep our heating and cooling systems updated and clean. I strongly recommend The Right Choice Heating and Air. They are fantastic. Thank you, Elie, for everything and keeping my family healthy! You're the bomb!"

"This was by far the best experience I've had when it involves repairs. My heater had been broken for a year. Because I'm on a fixed income, I couldn't afford to replace it. Quotes from others all recommended replacement. HD Mechanical gave me an estimate for repair and it was fixed right away, an at a fair price. Brandon and Tim are the best and are professional and dedicated to getting the job done without trying to upsell to unnecessary replacement. It works fantastic. They also happened to fix my ac as well, with no cost to me. If you are a woman alone, hire this company. They're honest and fair, and provide great service"

"I needed my HVAC system urgently repaired, the technician arrived promptly to resolved the issue. They were professional and knowledgeable and gave me honest recommendations & also was very helpful. Highly recommend! Thank you!"

"I am very pleased with the quality of work Matthew, Shawn and their staff did with the Main Sewer check valve replacement and the Main Shutoff Valve replacement. The Main Shutoff valve replacement and the Hydro Jet cleaning of the Main Sewer line was not part of the initial job to be done. Matthew authorized the added job without additional charge to the original quote I was given. Matthew and Shawn has great knowledge and answered all my questions to my satisfaction. They gave me a fair price, they were very professional, thorough and polite, from beginning to end. Clear explanation of needed repairs, sound advice without any inkling of price gouging or questionable add-on expenses whatsoever. Respectable and conscientious, could not be happier. Even very neat and clean. The people that worked with Matthew and Shawn were also very professional and very thorough. I will recommend them to my friends who need a plumber and call them again when the time comes I need a plumber. I will rate the work they did with A+ and Excellent!!!"

"I can't possibly rate this company high enough. I am very pleased with the professionalism of the office staff and the professionalism and promptness of my service person, Chris. My preventive maintenance window was from 10:00 a.m. to 2:00 p.m. and Chris arrived at 10:00 a.m. He set about to check out my A/C system, added R22 (is it still called Freon?) coolant and cleaned my A/C unit. What was also refreshing is that I did not get a hard sell for any additional products, services or systems.  I am a new customer and will be a repeat customer. I asked if they also maintain and service heating units and received a yes answer. They will see me again for sure."

"Albert was very polite, helpful and showed me some easier ways to maintain my system. He also offered suggestions on how to best utilize the 2 systems we have to best advantage. I was notified when he would arrive (along with a photo), then an update (as he was early), and work was completed in a timely, efficient manner. I would definitely use Southland Heating again!"

"The team worked eight hours straight in the heat. Cool air at last. A pleasure to have a contractor who knows what to do and does it. Showed up on time, cleaned up the work site. I highly recommend this contractor."
