    I've go through many AC repair companies in LA area last 15 years. Eric's service & price is by far the best.

    We called Eric back on a Sunday afternoon and on Monday morning he came to inspect and diagnosed the problem.

PUNCTUALITY 7. THOROUGH EVALUATION We met with the following specialists: SEAN O'HARA (AC repair) - AC stopped emitting cool air. Fixed issue w/ filter repair. ALFRED BIRNHAUPL (AC leak repair) - Fixed pipe leak from AC and completed comprehensive assessment of our dysfunctional zoning system. DOMENICK ALONGE (project manager) - Reviewed findings from Alfred, provided detailed indication of issues and resolution options with several quotes. Here's why our experience has been superior to previous companies: All three specialists were not only punctual, friendly, and courteous, but they took their time to evaluate our issues in CLEAR layman terms corroborated by photos, and showing us exactly where the problems were in person. We previously obtained a quote from a large corporate company and was left feeling dumbfounded and stressed as they described the nature of our problem in engineering, technical jargon that made absolutely no sense, including astronomical quotes without explanation of the work entailed. We continued experiencing intermittent issues with our AC and heater so we called Friends & Family based on their excellent reviews. This time around, with Friends & Family, we left feeling knowledgeable and reassured, with reasonable quotes including various discount eligibility. We didn't feel pressured by them to choose one route vs. the other; rather, gained the information we needed to make an informed decision that would prevent such issues in the future. Overall, their attention to detail, ability to explain the issues and resolution routes in simple, concrete terms, were far superior than the preceding company. They exceeded our expectations and we much appreciated their patience and openness to answering all our questions. I also want to mention that I was gardening when SEAN was fixing our AC. He saw me struggling to dig a hole for my plant and volitionally offered to help me. He took the extra time to dig the hole for me, exemplifying his genuine kindness and generosity! Similarly, my kids were running amuck and screaming and shouting while I attempted to maintain a conversation with ALFRED. He was very understanding and continued to engage in conversation, appearing unbothered by the chaos with a pleasant disposition. Lastly, DOMENICK was appointed on the day of our son's birthday. He related to us interpersonally and even helped assemble my son's new Radio Flyer bike! I told him that Sean also helped me garden and we laughed about how Friends & Family is a "one-stop shop." Given everything I mentioned, we're excited to have our overdue AC/heater system fully repaired by Friends & Family. We can't wait for our longstanding issues to be behind us, and we anticipate leaving an updated review once the work is complete!

Mike came out and thoroughly evaluated my system (which is 20 years old). Even though there wasn't one obvious reason for the problem, he carefully checked every possibility. He found that the refrigerant was low and that the pressures weren't resetting as they should. He recharged the system, reconnected my electrostatic filter, and took the time to explain what might be causing the issue, as well as discuss possible future options. Mike was incredibly knowledgeable, professional, and personable. I felt confident in his assessment and appreciated that he never tried to pressure me into unnecessary repairs or a replacement. I feel very lucky that he was my technician. I highly recommend Diamond Air Services!

I spoke with Barbara and I let her know my situation that I had two mini split units that needed a deep cleaning ASAP because I noticed mold was inside the units. Barbara confirmed with the technician and was able to set up appointment for same day with a small waiting window from 2pm-4pm! Other companies were giving me long waiting windows on when they might show up. I also love that she was able to give me an upfront price on servicing my two units!! Daniel and Eric were the two technicians that came out to service my units. Daniel was very knowledgeable, helpful, and kind. I explained the situation with the units and he was confident that he would fix the situation. Before he started, he let me know what he was going to do to deep clean the units and remove the mold and gave me another option just in case it didn't work. His confidence put me at ease as I was stressing so much about this mold situation. Daniel and Eric were very professional and we were able to get the job done and had my units looking brand new! They made sure there was no mess left behind and the areas that they serviced were clean. They showed up on time and actually a couple minutes early, which was a great surprise. I appreciate that they wore shoe coverings when working inside my house. I didn't even have to tell them or ask them. They already had the coverings and put them on before they even walked in. Overall, it was a fantastic experience and would definitely recommend to anyone needing service! Thank you for all your help and taking care of this stressful situation!

American Home Shield sent us (Michael Tyrone Wolf/Wolfepack Co.) people who checked my unit in 5 minutes, proclaimed it was an electrical issue and left without checking anything else. Their boss even called me up the next day to raise his voice at me because I had the audacity to leave him a 1 star Yelp review. I'm so grateful I found Trevor's company online. I begged him to send someone out on a Saturday - so rare! But Eduardo came as promised, spent an hour thoroughly examining our unit, confirming there was no electrical issue, but gave us the honest diagnosis that as our unit was so old, it would be extremely difficult to source parts. He said he could put a bandaid on it and keep revisiting the issue or we could invest in a new unit and even lower our electricity bill that way. We took the second option - and we are glad we did! AJ, Pablo and Marco came bright and early on Monday to work on everything. As I worked from home, I did not hear a peep from them. They did everything quietly and were a well-oiled machine. They were so thorough and took the time to explain things to me and my husband. They were genuinely happy to do their jobs. The 3 of them did so much back-breaking work all the way till past 6pm. We were so grateful for their dedication. When they finished, we had beautiful cold air coming out of all our vents. They cared not just to do the job well, but to make sure they left us happy and satisfied. The company founder Tom, even came out the next day to check if everything was done correctly. It was so lovely meeting him. We are going to be lifelong customers and we are spreading the gospel about these folks. One thing you need to make sure in Southern CA is that you find honest, hardworking HVAC people because our summers can get brutal and we can't afford to let our ACs malfunction for long. I am so glad I found Trevor and ABC. I trust nobody else.
