"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!"

"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."

"Perhaps the best thing about Morales Heating and Cooling was their responsiveness, via text and phone. Responded to my initial request first among several contractors. Was the only one willing to come out and give an estimate. Responded to follow up questions by text at all hours. Most of the contractors trying to contact me hadn't even bothered to read the description of the work I needed. Some even had a $3000 minimum. But Morales Heating and Cooling had a clear grasp of the scope of work. Scheduling the work was easy and convenient, and the work was done efficiently. Only a couple of minor issues - the estimate didn't have sufficient detail on the full scope of work and materials to be used, but that was cleared up via text; and I thought the cost estimate was higher than I expected. However, given that the other contractors weren't willing to provide an estimate or had outrageously high minimums, I felt fortunate to be able to get the work done so quickly. Already discussing have them come out for another project - A/C maintenance."

"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!"

"Mr Avery was extremely professional and very informative. He explained the price, which I felt was reasonable and fair. He explained the warranty process. Also informed me on how getting annual maintenance on hvac system extends life expectancy. Will have him out during the winter for a heating inspection"
