I have an HVAC system with 1990's Honeywall gas furnace and RHEEM electric AC unit and I had called…read morePIONEER HEATING & COOLING a few weeks ago because of their five star review. They send out a young guy who spent a few minutes in the attic and came out saying the furnace was too old, without a model name/number and it had to be completely replaced because they don't make parts anymore. I was a little taken aback because I thought they would still make parts. I walked into the attic and clearly saw the brand was Honeywell and took a pic/video for a 2nd opinion. Today I called DZO and spoke to Alex live and he said he had a technician, DENIS, that would know how to fix it and he would come by the same day. He came right on time and within five minutes he determined it was the circuit board. He was like McGuyver! Then he asked to check my AC which hasn't been checked for at least a decade and determined it needed some freon. He actually cared about getting everything working well-- I was VERY impressed. I will definitely be using them for any of my heating/cooling concerns and have already began recommending them to my friends. Thank you Alex and Denis for your commitment to caring and troubleshooting in a quick manner with reasonable rates (they don't charge to assess the situation).

The owner of this business, Matt Alba, is amazing! He's very knowledgeable and thorough when…read moreexplaining all the different options to fix your unit. I purchased a Cooper & Hunter 5-zone minisplit (ductless) system 11 months ago and had it installed by a guy who's now MIA. Fast forward 8 mos after install and the units aren't working right. My guy's phone number was disconnected but I got through to him by email and he came and allegedly fixed it. 3 mos later it's again not working right and my guy is again MIA and this time I can't reach him at all. Then comes the knight in shining armor... da, da, da, da... Matt/Dr. Ductless! I found him through Yelp. I reached out and he was a plethora of knowledge and eager to save the day, but, of course, since he didn't install my unit, this was going to be a big expense for something that should've been fixed under my labor warranty by the guy that installed it. But since my guy was MIA again, time to turn to the knight for assistance... Matt/Dr Ductless. Matt not only explained all the different possibilities to trouble shoot my system and all costs associated with each step but he went above and beyond and contacted my manufacturer of the units (Cooper & Hunter) to get feedback on what needed to be done. He also sketched out and measured the length from the compressor to each unit to calculate the total linear feet being used by the compressor and then spoke with the manufacturer to find out if I had too many linear feet which could be burdening the compressor. That wasn't the case but we did find out that one of the lines was too short so it needed to be replaced and coiled so the total minimum feet could be accomplished. He also saw that I had a lot of build up on the side vents of the compressor which he determined was because my laundry vent line was venting out of the house just a few feet away and the compressor was sucking the lint in and causing that build up (something no one else ever pointed out... and I did have one other guy come out to check the system and he didn't catch that either). I had to have my laundry lint line rerouted into the basement crawl space to resolve this issue (my contractor handled that). So, after much delimma over the cost (Matt was more expensive than the other guy I called out but you know the old adage, "you get what you pay for") and considering the first time around I picked the guy who was the CHEAPEST, I decided this time it was important to pick the guy who was the WISEST and that was Matt/Dr Ductless! His guys came out a few days ago and the 2 of them worked on my unit almost 5 hours. They found FOUR LEAKS where the units connected to the compressor (the same area my original installer who had come out 3 mos prior allegedly had "fixed"). Ends up my guy had tried a sealant glue on the copper lines instead of cutting, refluting and rewelding, like Matt's guys did. They also cleaned the vents on the side of the compressor thoroughly so no more caked up lint, and they replaced the short line with the new required 15 foot line. And lastly was the most important mission, the refrigerant. My guy had simply added more refrigerant the last time he came out. But, I found out that the manufacturer requires ALL refrigerant is VACCUUMED completely out of the system before replacing with new refrigerant, which required 11 lbs of refrigerant (and that stuff isn't cheap which is why the other guys only wanted to add more, not replace it). Of course Matt had his guys vacuum out all the old refrigerant and then replace it with 11 lbs of the new refrigerant (think of it like a car and the oil in your car, when you go for an oil change they don't just add more oil, they replace all the oil). So, obviously this was a very long story, but, the good news is, it seems to be DONE RIGHT this time! If you want YOUR JOB DONE RIGHT, don't hesitate to call the knight in shining armor, Matt/Dr. Ductless!!! My system now runs like a dream! Super quiet and ultra efficient! We hit 96 degrees only 2 days after they fixed it and my rooms now cool down in only a matter of a FEW MINUTES! Pics show before and after of the compressor being cleaned and refrigerant being readied. I didn't get any pics of the leaking lines but even I could tell they were leaking cuz they were covered in grease. IMHO, Dr. Ductless rocks!!!

Summary: - I paid…read moreDr. Ductless $189 for a diagnostic visit. - The visit lasted approximately 2 1/2 hours, including roughly two hours during which the onsite technician tried to reach a remote Fujitsu specialist. Once reached, the specialist participated for about two minutes. - The following day, my system displayed a new E99 fault for the first time and experienced materially worse cooling. - A CSR incorrectly dismissed E99 as "the same error." - The company explicitly refused to investigate the new fault or offer any response other than having me pay $2,200 for the proposed board replacement. - They denied any responsibility without returning, inspecting the new condition or performing the Fujitsu-prescribed E99 checks. - A promised supervisor callback never occurred, and my detailed email and E99 photograph received no reply. Before the visit, my Fujitsu multi-zone system had consistently experienced an intermittent E22 fault. Fujitsu's model-specific service manual indicates that, if the installed indoor-unit combination is valid, the outdoor main board is the likely cause. I therefore agree that the proposed board replacement is a reasonable diagnosis for the original E22 problem, and I was open to proceeding. After the visit, however, the system displayed E99 for the first time and cooling became materially worse. Fujitsu identifies E99 as a different fault--a 4-way-valve error--with a separate diagnostic procedure. For E99, Fujitsu directs the technician to check connectors and wiring, indoor thermistors, the valve solenoid coil, the mechanical valve and the board's valve output before blaming the main board. Some of those possibilities involve connections or components that could potentially be disturbed accidentally during inspection or testing. I am not claiming that the technician caused E99. I asked the company to investigate a new fault that appeared immediately after its visit before I paid $2,200 for a repair that might fix E22 while leaving E99 unresolved. Instead, the company expressly refused to perform any further investigation, denied responsibility without examining the new condition and continued insisting that the only option was the $2,200 board replacement. This conclusion was offered despite none of the separate Fujitsu E99 checks having been performed. The contrast in responsiveness was striking. When I emailed about paying the $189 invoice, the office responded within minutes. When I reported the new fault, supplied an uncropped photograph and requested technical follow-up, my email went unanswered and the promised supervisor never called. The business relationships were also unclear. My service was booked and branded as Dr. Ductless, but the service van was labeled Temp Air System, and the email with the estimate was from Temp Air (the PDF estimate was from Dr Ductless). Temp Air and Dr. Ductless publish the same Lawndale address, while Dr. Ductless's website also contains Southland Heating & Air material. Consumers should not assume these names represent completely independent service organizations; verify which legal company employs the technician and will be responsible for the work and follow-up.

He even told me that he would not charge if the fix didn't work. AND he had the part we needed with him in his truck. He got our A/C up and running in like, 20 minutes!

He discussed potential issues (our unit is very old) and provided honest feedback about what could potentially help, but making sure we understood that these fixes were not guaranteed to resolve the issue as essentially the unit needs to be replaced. Simon was very thoughtful and understand our situation, he offered solutions that might meet our needs, but did not pressure us into making a choice. While we have not hired anyone yet as we are figuring out if we should repair or replace, I appreciated the time and effort Simon put in, and he did not end up charging our service fee either. Definitely will consider them for the job if we proceed with it.

Anyways, fast forward and my A/C unit needed a deep clean last week and I couldn't find Anthony's information so I ended up calling another company for a deep clean quote. They said they can offer me a discounted $1,250 deep clean on my AC unit and the technician was pressuring me into this saying it was the best deal I could find. That seemed crazy, so I took a couple hours digging around receipts and old emails to see if I can find Anthony's info and so glad I did! Anthony sent a technician who did the deep clean AND put me on a maintenance plan for one more visit at $450. Way better deal and felt that they were honest and upfront. He probably could've upsold me but didn't, which I appreciate. Definitely recommend them for doing honest and good work which is rare these days.

I have relied on DNA Heating & Cooling for the past two years for emergency service, minor repairs, and annual maintenance. They consistently provide outstanding workmanship, expert knowledge, fair and transparent pricing, and exceptional customer service. Their response time is incredible--especially during periods of extreme heat--and every customer is treated with respect, appreciation, and genuine care. My most recent experience was this morning after my air conditioner completely stopped working late last night. My Nest thermostat displayed an E74 error code, and with the current summer temperatures, I was extremely concerned. As a single senior citizen living in a two-story condo, the upstairs living area heats up quickly. I've had my sun-facing windows professionally tinted, installed a UV sunshade on my balcony to reduce the heat coming through the large sliding glass doors, added ceiling fans throughout the home, and even installed Blackout EZ Window Covers in the master bedroom--yet without air conditioning, it still becomes unbearably hot. I contacted DNA Heating & Cooling last night, and they responded early this morning. Andrew arrived within 20 minutes, diagnosed the problem, explained everything in terms I could easily understand, and had my air conditioning running again in no time. He never tried to sell me anything I didn't need and made sure I understood exactly what the repair involved. He finished in less than 30-minutes. Finding a company that is honest, knowledgeable, dependable, and genuinely cares about its customers is rare these days. DNA Heating & Cooling has earned my trust, and they will always be my first call for HVAC service. I highly recommend them without hesitation to anyone looking for a company that truly stands behind its work. Thank you, Andrew and your entire team, for another outstanding experience!
