We hired Diversified to do a much needed replacement on our outdated AC system. From start to finish it was all smooth and they were extremely professional. The craftsmanship and quality of work exceeded our expectations. They brought an entire crew over and did all our ductwork, removal of old system, installed new coil, relocated a condenser, and put in a new furnace. Very happy and would recommend them to anyone. Thank you guys again! read more

Gary and AK came out to install a mini split in our garage that we are finishing off and turning into an art studio. They were great and did a wonderful job. They walked me through any questions I had and were very professional. I would highly recommend Diversified. read more

Had my 3 mini splits serviced today by Pat...He was kind, polite, respectful and very thorough....quite knowledgeable! I really appreciated all the time and care he gave to servicing my 3 units and the compressor outside. I am impressed by the service i received today and will request Pat in the future, although Paul was always great too! read more

I called Diversified after my old AC company, while nice, just couldn't figure out the real problem. Diversified was super efficient and honest with their diagnosis, and they finally got it right. I've now used them twice for different units, and the experience has been just as great each time. Paul came out earlier this week on short notice and couldn't have been more awesome. He even went back to the house to follow up with the service. Couldn't be more satisfied. From now on, they'll be my go-to, and I'd happily recommend them to anyone. read more

One star is generous. I called diversified, to have my evaporative cooler summer ready; my husband used to take care of that-- he passed away. I assumed that the cooler might need freshing up, but the serviceman said, I only needed a belt. Next month it had stopped cooling; they replaced the pump. Next month, the house was like a furnace, they replaced the pads. This month, the cooler sounded like a cage full of turkeys screaming to get out; replaced the pulley, bearings, and another belt. read more

Great company and value! Fast and easy scheduling considering I'm a long-distance owner. Nick was awesome, explained everything on the phone, sent me videos. Solved the cooling problem - due to contractors running AC while grinding the floor. They will be my only contact for my AC in the future. read more

Paul came out from Diversified on Friday, June 13, 2025 for an A/C repair in Morongo Valley and quickly identified the problem, wires crossed and he fixed it, efficiently, at a low cost. He also made some recommendations to avoid costs in the future. He answered all our questions and is quite knowledgeable. I would highly recommend Diversified for A/C repair services read more

Dear Diversified, Thanks for coming out ASAP and fixing my leaking mini split without charging an 'emergency' fee for visiting the same afternoon. Thanks again for sending a knowledgeable employee to not only fix the issue but show us what it was and spend time helping us understand how to maintain our systems better. Really appreciated all the time and effort he put into getting us back up and running again, and would definitely use you in the future and recommend to others! Thanks again for everything, Liana read more

Diversified Heating and cooling in Yucca Valley is a Great Company. They service my air and heating unit ...Super Nice and Super knowable ...Last year they replaced my air ducts and the job was perfect along with their kindness. It was a pleasure doing business with them! read more

I recently had to replace my air conditioning. I contacted 3 places for a quote. The first place never showed up. The second wanted a 50% deposit which is actually against the law. And they did not have a license. I also contacted Diversified Heating & Cooling. Corey arrived on time to take a look and do the quote which he did while there. He did not try to push me into saying yes right away. A week later I let him know that I would like to go ahead. That was on a Friday. On Tuesday morning they arrived to do the work. All of the workers were friendly and hard working. The whole job was done in a day. They cleaned up everything and took away the old equipment. They all obviously knew what they were doing and we are very happy with the work they did. I would definitely recommend them. I did also check that they are fully licensed and insured. read more

If you want mini splits definitely give them a call ! Been wanting to get a mini split for my small home in the desert for a long time . Called around a few local companies to get estimates and decided to go with Diversified. Spoke with Robby several times , he came over to give me an estimate and answered all my questions he explained the different options so I was confident when I made my decision since it's not a cheap project, but definitely worth it . They were great to work with . Aiden and Akili came to my house to do the installation. Both were very knowledgeable, polite and professional . read more

Good people. I had to reschedule due to a change in my travel plan while I was overseas and Pam took care of it smoothly. Paul came and fixed a couple of leaks and he was very professional and friendly. read more

As a homeowner new to California, working with Diversified for years eliminates the guesswork from HVAC expertise! Recently, I found out Diversified Heating & Cooling could be the only technicians in Yucca Valley that offer their services to include dryer vent cleaning. The value-added servicing and working with Diversified is affordable peace of mind! But, you'll remember the crew who work with you maintaining your HVAC system and more! read more

They do good work but boy are they expensive! Had them over this month to locate and repair the coolant leak in my mini split system, charge it back up with refrigerant, tidy up the line sets and add metal covers over them. $2400 for one guy out there for 4 hours. Even with travel time and supplies that like more than lawyers make! Don't think I'll using them again unless I win the lottery. read more

These guys really are stellar. I had them come out to service my cooler on the roof. I usually do it myself, but I am unable to climb a ladder right now, and the weather is warming up. Now I am questioning why I never called them to do the annual service in the first place since they did install it quite a few years back. All of the grief and trips to home depot for parts, I am kicking myself for not calling them sooner. Paul was the tech. He was very friendly and courteous, and got the cooler ready for summer in a timely manner. He said the front media pads are close but they will definitely need to be replaced next year for sure. The honesty is greatly appreciated! I'm actually surprised they haven't had to be replaced yet. Thank you Diversified! See you next season for sure! read more

Called diversefield heating, and they were great, service technician Nick was not only courteous but was very knowledgeable and honest, also encountered pleasant conversation with customer service rep pam. All in all great company with geat pricing , company saved me a lots of money , when a different company was telling me lie's about my unit and asking for more money, diversefield said it was just a fuse and only charged me 65 dollars and that was just the service call. Thank you diversefield, you've definitely earned my trust and business! read more

I have used Diversified since they started. Their employees are knowledgeable, profession and courteous. They show up when scheduled and I trust them to do the job right. I wouldn't even consider calling another company. read more

Strike 3: Diversified cancelled an appointment they made for me on the morning they were scheduled to come out, *after* the service start time, and then offered me a replacement date -- in a month. At no point did the words "I'm sorry" come from the mouths of the two people I talked to. Strike 2: For an earlier service call, their front office had assured me that they had experience with my heat pump models. I checked and double-checked, and they rather dismissively assured me they had experience -- which was untrue. Strike 1: Last, for another call I had scheduled Paul for a tricky job, since he is an excellent, thoughtful technician with more the 35 years experience. They agreed, then swapped him for an inexperienced tech who had never seen 'anything like' the model I double-checked with their office. read more

AVOID!!! Back in October I checked my heater and it wasn't working. I had Diversified come and they diagnosed the problem and said they would arrange a time to come out and fix the problem. I waited and waited and finally one day out of the blue a different guy showed up. Ok. He asked me what had happened when the first guy showed up and what he had said and seemed completely confused about what was going on and why he was there. He got on the roof and did some stuff for about an hour and then told me that not only what they had diagnosed earlier was a problem but that I needed an entirely new thermostat system. Great. So, he said they will contact me as soon as the thermostat comes in. I waited a week and then called them to see what the problem was. They didn't know why it wasn't there but assured me that they would find out and get right back to me. They didn't. A couple days later I called again. Same routine. At that point I started calling about every few days. Each time I called, they seemed completely confused and acted as if it was my first time calling. They would say they would call me and never did. Another week and more of me calling them and the same clown routine. Yet another week and again the same clown routine. Finally, at the end of four weeks another guy randomly showed up at my house. Fine. I was used to their scatter brained service at that point. And again, it was the same ordeal. He was confused as to what he was supposed to do and what the people before him had done and the only person he could ask was me. What the hell do I know? I'm the customer! The guy finished and he said they will send me a bill. Not what I wanted and inconvenient but whatever. By this time it was early November. Come late December, the bill arrived in my mailbox. It's holidays, crunch time at work, and Christmas. December 28, I put the bill in the mail. That same day they called to tell me I have an overdue bill from November. I told them I got their invoice a week or so ago and the check is in the mail. She got upset and was concerned the check won't get to them before the end of the year and goes on to accuse me of not paying them when they sent me an email invoice. However, back here in reality, they never sent me an email which she discovered when she tried to make this my fault. She said they never got my email address. Not my fault. She continued to make this situation out to be my fault and even said that when I didn't receive a bill right away that I should have called them. Seriously? I let her know I didn't appreciate her trying to make this out to be my fault but she doubled down and continued to play it off as I had done something wrong. I asked if she was a professional or not and she responded with a threat that she'd put a lien against my home "because she's a professional." Obviously, she can't do shit and is trying to cover the moronic buffoonery over there. So, yeah, if you want a job to take a month, have guys show up at your house without calling first, ask you to tell them what they're doing there, have the inconvenience of not being able to pay right away, wait for over six weeks to receive your bill right before Christmas, and then be accused of wrongdoing and threatened for doing nothing more than putting a check in the mail, then these are your people! read more
