High quality service and workmanship. I put out a request for AC installation quotes on Yelp last week and Roman was one of the first to respond in detail. He paid me a visit about 12 hours after my initial outreach and was so frank in his assessment and pricing that I didn't feel the need to get another serious bid. That trust was well placed because he and his team (Miguel, Diego) executed flawlessly during their installation. Excellent communication throughout the entire process and mission completion one week after we first spoke. The Purified Air team takes pride in their work and business, and I can appreciate that as someone who wants to avoid these expensive endeavors as much as possible. read more

I hired Purified Air to run a maintenance cleaning on my old AC unit before the summer. They were quick to respond and schedule an appointment. I appreciated that they gave me a two hour window as opposed to your typical four or six hour windows given by other maintenance services. Came over and serviced my unit. He was communicative and clear. And the price was very competitive. I would hire them again. read more

**UPDATE** | want to update my original review by saying that Roman reached out after this was posted and acknowledged that the service that was provided was not up to his standards, and he graciously refunded me my service fee. We all have off days, and I really appreciate his candor and circling back to me. After we realized one of our rooms wasn't getting airflow from our AC unit, I searched in yelp to find someone to help us figure out the issue. This company popped up for me, and even though there was a $100 service fee, with all the positive reviews, I felt confident that this company could help with our issue. Roman came and looked at the vent from the room side, and then climbed a ladder to look into the attic where the AC ducting pipes are. However, he couldn't see the pipe from the ladder/attic opening and never checked where the faulty pipe was actually located, which would require him to climb into the small attic space. Despite not seeing or looking at the affected ducting pipe, he told us it would be $1200 to replace it and fix our issue. I didn't quite understand how he could come to this conclusion without actually seeing the pipe, and he insisted this was what needed to happen. This didn't make sense to me, and before I paid the $100 service fee, I called again, wondering if we could just have someone else come back and actually look at the pipe. He said when they come and do the $1200 job, they would. Disappointed, I reluctantly paid the $100 service fee, but didn't really feel like we got a real assessment. Fast forward to a week later, we had someone from another company come who immediately jumped into the attic to look at the AC ducting pipe without us even saying anything, and lo and behold, the pipe to that AC vent was just squished down, blocking the air flow from going to that room. I ended up with a bill of about $200 and our issue is completely fixed. read more

I needed a small job done (replacing my HVAC filter that is in a difficult spot) and messaged them on Yelp during the late morning. A few hours later Roman came out and quickly changed out my filter. He was kind, polite and I'd definitely call this company next time I need their services. Thank you! read more

Have nothing but good things to say about Roman. He was able to come out to my house same day and fix my broken central air conditioning. Not only did he get it back up and working for me quickly, he also spotted an unrelated maintenance / safety shutoff issue that I knew was a problem already (I just forgot about it). I really appreciated his attention to detail, his reasonable pricing, and his ability to help me out very quickly. Will definitely call him again next time my system goes down in this LA heat! One more thing to note is Roman was the second person I lined up to give me a quote. The first company wanted to do all of this unnecessary work replacing a circuit board I knew wasn't fried (my family is in HVAC business). I called Roman to get a second opinion. Glad I did. It was the issue I thought it was (fried contactor on the roof), which was the issue the first guy also found, but Roman did not include the extra 800 dollars worth of work the other guy tried to charge for parts that didn't need to be replaced. They also missed the issue Roman reminded me of. read more

My first experience with Purified was excellent. (The work was just completed today, so I can't speak from long-term experience with the repaired system.) I had a very small window of time before leaving town; Roman came out and assessed the situation the same day I called, and arranged for the work to be completed the following day. Roman supervised the whole process, he was professional in demeanor and an excellent communicator. Diego spent much of the day in my attic replacing ductwork--he was courteous, conscientious, and efficient (he actually showed up a few minutes before the appointment window began). Everything seems to be working very well, I would recommend them. read more

Purified Air Heating and Air Conditioning came through today (a Sat) when we really needed it. Roman texted me ahead of time with his photo and let me know he was on his way about 30 minutes before our 11am window started. He was thorough in his assessment, clearly explained the options, and handled the repair professionally and with a great attitude. Super friendly and is very knowledgeable. Everything happens for a reason...yesterday's disappointing experience with another company led me straight to Roman and Purified Air. Now we have a reliable go-to for all our HVAC needs in the future. Highly recommend! Thanks Roman! read more

Contacted this wonderful company and received a quick response. Roman came to inspect my quite old unit as I didn't know how or where to locate the filter. Roman immediately identified the unit. He inspected the unit both indoor and outdoor. He also provided information regarding correct filter and tools for future filter replacement. It was a pleasure to work with him and his knowledge inspired confidence in his service read more

Purified Air - Heating And Air Conditioning - Split unit in my garage - Heating & Air Conditioning/HVAC Near Me - Pasadena, California

Bottom Line Upfront: I had a great experience with Purified Air Heating and Air Conditioning and I wouldn't hesitate to contact them for my HVAC service needs moving forward. My air conditioning unit went out in May (2025). The weekend after, temps hit 95* over the course of several days. Per Yelp's project recommendation, I found Purified and I messaged them about servicing the system. Roman Z., from Purified, contacted me promptly and requested some additional information through the Youtube messenger and by phone. Shortly thereafter, Roman came out to look at the system. He was professional and patient in explaining the issues and viable options to resolve. I was able to research the options and I opted to trust Purified with the HVAC overhaul. On install day, Roman and the team were timely, professional, and cordial. The team removed the old AC and furnace and had the new functional system quicker than I expected. I was comfortable with every facet of this project after communicating with Roman and the team and the overall value, stemming from peace of mind and costs, was tremendous. I will keep Purified on dial for my HVAC service needs moving forward. read more

Roman was very friendly, courteous (wore covers for shoes), knowledgeable and efficient. Would definitely hire again for future work!

Roman, Miguel, and the whole crew were fantastic. The work was high quality, the attitudes were even better! They replaced our 21 year old HVAC and gas furnace with an electric split system and were able to get it done within a few days of the initial consult. Price was appropriate for the quality of work and equipment. They deserve your business and all the ice cold beverages/popsicles you can offer :) read more

Roman was extremely helpful and kind. Top notch service ! Would def recommend him and use him again !!

Roman was fantastic. Was able to service our AC unit for a business in a few hours after calling. We will definitely use his services in the future. read more

My air conditioning unit suddenly stopped working and Purified came out to do a diagnostic and give me a quote for repair. It was $95 for the diagnostic and he quoted me $1200-$1500 to repair the problem. I then got three different companies to come out so I could benchmark pricing. All three of them had totally different assessments of the problem, but the third company recommended to me by a friend told me it was a very simple problem that took one hour to repair and cost me $250. My AC is now repaired, working perfectly and immediately cooled the house. My point being I don't know anything about AC repairs, but definitely get second and even third opinions and don't just rely on yelp, but ask friends or neighbors for company recommendations. read more

Roman replied quickly and was able to get scheduled a day after. The repairs were quick and easy with an honest assessment of the situation. He wasn't pushy or try to sell more than I needed which i appreciate it. Will call back when needed. Thank you read more

I was quoted $2k by another supplier to replace the blower motor in our unit so I ended up calling Purified Air Heating and Air Conditioning to get a second opinion.

I highly recommend this company if you're having issues with your AC unit. read more
