A colleague of mine recommended AD Mechanical as I needed some service on the gas furnace at my house in Redwood City. The heater is 25 years old and I was thinking I was going to be told I needed to fully replace it. Adlan showed up and connected a few sensors to the internal control board of the furnace. He said that whoever last worked on the furnace set the "inches water column" too high so he adjusted that down. Also my wife had a decorative cover over the air intake in the living room that was causing the blower to work too hard. These two issues together affected the performance of the gas furnace. Other than that he told me the furnace still seemed healthy! He didn't try to upsell me anything. Very friendly, prompt and professional. Absolutely recommend AD Mechanical for all things HVAC!

We are so grateful we found Adlan. Another HVAC technician had looked at the rust and water marks around our attic furnace and told us the furnace was failing and could eventually become a carbon monoxide risk. We were advised to replace the whole system with a heat pump, which could have cost us more than $15000. It was stressful because we had no idea whether the furnace was truly unsafe or whether we were being pushed toward a very expensive replacement.
Adlan took the time to inspect everything carefully instead of immediately trying to sell us a new system. He found that the furnace itself, blower, ductwork, and drain lines were still in good condition. The water problem was caused by a loose pipe connection that had not been clamped properly, along with a partially clogged drain. He tightened the connection with the correct tools, cleared the drain, and adjusted the gas pressure back to the manufacturer’s recommended level.
He explained everything in a calm and understandable way and showed us exactly what he found. After the repairs and maintenance, we felt much more confident about the condition of our system and avoided replacing equipment that did not actually need to be replaced.
Adlan never made us feel pressured. It is rare to find someone who focuses on solving the actual problem instead of selling the most expensive option. I would absolutely recommend AD Mechanical to anyone looking for an honest HVAC professional.

I had a wonderful experience with Adlan. Our 20 year old AC unit stopped working and he quickly diagnosed and fixed the issue on the spot without trying to upsell anything. Beyond the quick repair, he took the time to walk me through his process for diagnosing/assessing our AC system as well as the steps for a routine furnace maintenance - I learned a lot along the way. Highly recommend Adlan!

I had a great experience with Adlan from AD Mechanical. My 12 year old Payne AC suddenly stopped cooling, the outdoor fan was running, but the compressor would not start. Another company had already tried a capacitor and hard-start kit and concluded the compressor was locked, but the replacement estimate was much higher.

Adlan came out, did a careful diagnosis using professional tools, and clearly explained what he was checking. He confirmed the compressor failure, offered a very fair quote, and was able to replace it with a compatible and better than original (LG) Copeland compressor. He also replaced the capacitor because the old one did not match the new compressor spec, replaced the filter drier, cleaned/vacuumed the inside of the condenser, straightened some bent fins, and documented the process with lots of photos.

After the repair, he tested the system properly. He measured the return air and vent temperatures inside the house, return was around 71 and the supply vents were around 46 to 51, and the system was cooling well again. He wore shoe covers inside, was respectful of the house, communicated clearly, and was super courteous throughout the whole job. It was a great pleasure working with him. No attitudes, no drama, just down to earth hard and professional work, that's it.

What stood out most was that he stuck to the original quoted price even though he used a better but more expensive Copeland compressor and additionally replaced the capacitor, which exceeded original estimate scope. I even offered to increase the payment, but he politely refused.

Overall, Adlan was very professional, honest, skilled, and very fair on pricing. Based on my experience I would absolutely recommend him for HVAC repair.

Adlan is extremely professional. Great technician, on time, diagnosed well & fixed our washer issue quickly.
He also gave some tips for us to avoid running into similar issue. Loved working with the Adlan due to his genuineness and definitely calling him back for similar future issues.

Mr. Adlan did an outstanding job servicing our furnace and AC system. He was extremely thorough, carefully inspecting every component, taking precise measurements, and identifying and resolving an issue with the condensation drain. His professionalism and attention to detail truly stood out. It’s reassuring to know we can rely on him for future service needs.

I have worked with Adlan on two separate occassions. The first issue was quite challenging. The problem was quite intermittent and it does happen under certain weather conditions. He step-by-step emulated the problem and finally corrected it. This particular furnace issue required an expert and a geat engineer, such as Adlan. He never charged for each visit. Once he finished the job, he took the time and explained me what he did for my own understanding. I also called him for another AC job. He did a fantastic job and even located the PCB assembly less than 24 hours. Highly recommended.
