I recently had a full HVAC replacement done and worked with Mark for the installation. The whole experience was excellent from start to finish. After getting a few estimates, I decided to move forward with Mark for the job. My old system had a refrigerant leak in the evaporator coil and it wasn't worth repairing anymore. Mark walked me through the the different options clearly and made recommendations. We decided to replace our system entirely with a Trane heat pump setup. He explained everything in a way that was easy to understand without any pressure. What really stood out is that he went above and beyond during the installation. He sealed the cavity below the indoor unit and installed insulated reflective panels around the area to improve efficiency and airflow. He also replaced the threshold in my utility closet with sheet metal to properly finish the space and make everything look clean and professional. Another thing I appreciated was how careful he was inside the house. He wore shoe covers while working indoors and laid out mats from our door to the work area and was very respectful of our home. The installation included the new outdoor heat pump, air handler, coil, electrical disconnect, and proper commissioning. He made sure the airflow was set correctly and scheduled a HERS verification so the system meets California energy standards. The system is running great and the house is comfortable again. It's clear Mark takes pride in doing things the right way and not cutting corners. I'd definitely recommend him to anyone looking for a knowledgeable and trustworthy HVAC pro. He's now my go to. read more

Mark showed up the same day we needed him...thank the Lord. Our AC went out, and he was there six hours later, exactly at the time he said he would be. He was extremely professional, explained everything clearly, and showed us what he was talking about whenever possible. I really appreciate the nononsense service he provides. I've had bad experiences with a couple of other HVAC companies, so finding one that's dependable and reasonably priced is worth its weight in gold! I highly recommend this company!!! read more

My AC broke down on Sunday afternoon, and we were having a hot day. I messaged Mark at Cityflow and he responded right away and we set up an appointment the next morning. Mark did an excellent job of getting my old HVAC system back up and running, and upgrading some of the components so that we will need fewer repairs in the future. He was clear and concise about what needed to be done to repair the unit. The bill made sense and was reasonable for the work. I was very impressed with his level of service. He also offers a maintenance plan. It far surpassed my expectations. I highly recommend Cityflow. read more

All around wonderful experience with Cityflow! Quick response time, easy to set up an appointment. Mark is honest, helpful, friendly, knowledgeable, and gives you thorough information. He fixed our AC quickly. I'm so grateful to find Mark and Cityflow! read more

Mark was very professional. We especially liked that he came in and put on shoe cover ups when he came inside our house. He was very knowledgeable and went above and beyond to explain what was wrong with our heater. He even sent notes when he discovered that the warranty for our heater had to be replaced by the original installer and didn't charge for the extra visit to bring a part to my home. Will definitely call him again to continue servicing our HVAC unit. read more

On Saturday, my heater was not working. I used Yelped "projects" to get quotes for someone to come out and fix the heater. Mark responded within a few minutes of me posting that I needed to fix my heater. He said he could come out on Sunday between 8 or 9AM to check it out for me. Mark showed up timely at 9AM and started to check out the heater. It needed a new filter and maintenance. Mark was very knowledgeable and explained to us what we could do to resolve the issue going forward. He also suggested that we replace the thermostat as it was the original one. If you need help with your air conditioning or central air, I highly recommend Mark and his crew. They will get the job done. read more

Our heater stopped working. After messaging this company for an estimate, they came out the very next day. Fixed and did maintenance on the furnace. Very knowledgeable and friendly. Reasonable pricing for the entire job. He will definitely be our go to person for any issues in the future. read more

We had a great experience with cityflow heating and air, specifically with Mark. He came out to help diagnose our heating issue and was prompt, helpful and friendly! Mark was able to fix our heating issue same day and was so kind to my toddler who wanted to help him do everything. I would call Mark with cityflow for any future heating and air needs again! read more

Mark is the best. I left a voicemail after hours and he called me back right away and helped me troubleshoot the problem. He also came first thing the following morning to follow up. Even though he had a flight to catch later that day! We unfortunately had to replace our old system but he was very straightforward with the pricing and got the work done quickly! read more

Mark saved us today by coming within an hour and taking thorough care of our issue to get our a/c back up and running on a 100+ degree day. Really appreciated him educating us along the way and wearing booties in the house as well. We will be using Cityflow for our systems moving forward! read more

I received an excellent service from Mark who efficiently diagnosed my HVAC Iissue and fixed it. I highly recommend this business.

Mark was recommended on a Facebook group to me. When our heater went out we called him up and he was able to come over shortly after same day to diagnose the issue. He located the part needed, ordered it, and promptly installed it the day it arrived. He was easy to communicate with, reasonably priced, and very professional. We would hire him back for our next HVAC repair need. read more

These guys are top notch! They came out the next day to fix the capacitor and got our AC up and running. This was two years ago. Now we had an issue with the blower. I sent them pictures to share what was going on that helped diagnose the issue and they helped me get it going again as it was just a dirty filter causing the coils to freeze. Saved me time and money by helping solve my stupidity for letting the filter get dirty without wasting his time coming out during a heatwave. Will be the first team I reach out to next time too. read more

Mark took care of our heater. Professional, great attitude. Definitely recommend! Thank you

I needed regular maintenance done on my hvac system, and a drain on the a/c needed to be unclogged. About 3 weeks ago, I happened to find a door hanger flyer from Cityflow on my porch. I checked Yelp and saw the good reviews. I called Mark, he came in 2 days. He replaced the filter, serviced my rooftop a/c and heating system, and he fixed the clogged drain, in almost 100 degree weather. He was friendly and courteous. He even wore shoe covers to protect my carpet when he came into my house. I would not hesitate to call Cityflow again for any hvac needs. Thanks Mark for your professional service. read more

Mark is really the wonderful. I had issues with my heating. It was a dual zone and would switch off. I was quoted by 2 different companies, one was $23 K, and the other $16 K. Mark came over and fixed the problem in minutes and did not charge me. Cityflow is super clean, very polite and extremely thorough. I have since seen him one more time and have already scheduled my maintenance for AC and heat. My sister and mother both use him as well. SO happy to have him be part of the reliable people I can call. BTW he does everything HVAC. read more

Mark was recommended to me by a friend when my HVAC system went out. Mark was professional and a great person from the initial start, and to be honest, felt like I was working with a close friend. He quoted the job fair, provided clear timelines, and the job was on budget and on time. Overall exceptional work and professionalism. I'll continue using him for future projects because of my experience. read more

Mark was efficient and honest. He completed the work we requested in a timely manner and with up front cost.

During smack dab summer, it's been a challenge to find a reliable HVAC company that would come out to do service for our business' AC systems, but the owner Mark at Cityflow was quick to respond with a set time and date along with a more than fair price. On the day of service, Mark was punctual, professional, and thorough with his work. He took the time to explain everything he was doing and why, and he made sure that I understood the problem with my HVAC system and the steps he was taking to fix it. I was very impressed with Mark's knowledge, skills, and professionalism. He made the entire process of scheduling and receiving service a seamless one. Mark will now be our go-to for all HVAC needs. read more

Great service. Mark went beyond making sure my air conditioning unit was top notch. I would recommend his company to anyone that wants great service at affordable price. read more

Excellent work,, very impressive, really happy with the system , Mark really knows what he is talking about, he did what other companies said it was not possible! Thank you very much Sir . read more

Mark is fantastic. My AC went out during the heat wave and he found a way to be at my house the same day I contacted him. I realize that is rare in his schedule so I was stoked it worked out. Mark guided me with options, and I felt like he was working with me to solve the problem rather than upsell me on unnecessary costs. Mark had my AC pumping cool Air in less than an hour from him being on site. Update: I made an error when installing a new thermostat two weeks after Mark came. I called Mark, and he helped me problem solve and explained I likely popped my fuse. Sure enough, he saved me a lot of money and recommended I head to Autozone for a $5 part. I highly recommend and he's earned a customer for life! read more

I've had CityFlow come out a few times to repair work from other companies, and each time they've done an amazing job. They can help identify problems quickly, get the repair taken care of, and let me know upgrades to help the system run efficiently (without pushing the upsell). I will continue to use their services to help maintain my system, thank you Mark! read more

I recently used Cityflow's ac service and had a fantastic experience. Mark was professional, and highly knowledgeable. He quickly diagnosed the problem, and explained everything clearly. I highly recommend their services for reliable and trustworthy AC repair. read more

Mark is an extremely honest and one of the most positively helpful contractors. He was readily available. He took my call and even FaceTimed to help me through the HVAC unit which needed to be unlocked. He shared a video and was incredibly patient. I genuinely appreciated his help and will utilize his services without batting an eyelid. I strongly recommend Mark. read more

Mark and his team were great. They were prompt, friendly and a hard working team. It only took 1-1/2 days to complete. I am forever greatful that I talked to my neighbor about a/c and heating. He gave me Mark's name. I called Mark and I had an estimate in two days. Mark was great to work with as was his team. It was extremely hot and not one of them complained. The quality of work from Cityflow A/C and Heating is a five star rating from me. If I had any questions Mark always got back to me. I highly recommend Cityflow to anyone who wants great service. Thank you Mark and team. You've made me a very Happy person. read more

Would highly recommend Mark/Cityflow for your HVAC needs. We had an old furnace that was no longer kicking on. We ended up getting a new furnace and AC system instead of repairing. Mark went above and beyond, even coming back a second time to explain the process and go over details with us and help us make a truly informed decision. We appreciated the excellent communication skills and timely schedule. They even took the time to do some extra work that we didn't initially anticipate like wiring, patching, painting, etc. without unexpected extra cost. And now we have a brand new system that works better than the old one ever did. read more

Mark was really quick to respond, I let him know the issue I was having and he was able to book me in at a reasonable time. He explained what he found, fixed the issue for me in a timely manner, and recommended maintenance on my AC. As a first time homeowner, I feel confident i made the right choice. I had other techs come out to help me with my AC in the past and none explained the work done as detailed as Mark did. read more

I had an issue with my AC that needed to be resolved quickly. I texted Mark in the afternoon and sent him a few images and he was able to get me a very competitive quote (I got 4) within 60 minutes. He came out the next morning on time and finished the job. Mark is very professional and it's clear he takes pride in his work. read more

I reached out to Mark early in the morning with an inquiry regarding my mini split unit. He promptly replied to every question and helped narrow down the problem even before coming to service the unit. He was honest and never tried to upsell something that wasn't necessary. He just advised Freon was needed and was able to add some to our unit. He doesn't overcharge or take advantage in anyway. Truly appreciate him coming within such short notice and really helping us out during a heat wave! We will be using him again whenever service may be needed. Thank you! read more

I want to give a Five star to Cityflow Heat and Air, Mark went above and beyond, not just saving the day but the night too. I have tenants in my house I rent, and the AC has not been working few days and we got this hot wave during the weekend, on a Sunday they reported to me about the problem , I call Mark on a Sunday afternoon really expecting to get some service at least by Tuesday... and I was just amazed he was on calls on a Sunday. he gave me a time to come by and check the unit later on the early evening, he showed up and Check, clean, replace and change parts on the unit . Mark responded all text and keep me on the loop during and after he was done My tenants where really happy and me too. I will keep recommending this company to friends and clients. Thank you Mark. read more

Mark was excellent to interact with. He was very professional and did the job well. He also discussed problematic issues and listened to my needs without being pushy or trying to sell me more services. I will definitely use his services in the future. Air duct cleaning read more

Mark was available to come out and look at my units the day after I called him. He was very knowledgeable and professional. He was able to solve the problem on one unit and for the other unit, he suggested we try something and if it didn't work he would credit me back for the part. He was extremely honest and didn't try to sell me extra expensive parts that I didn't need. read more

Got recommended to Cityflow through my co worker. Had to get a tech out to my parents house after their unit was acting up, wasn't really trying to deal with games or gimmicks like I have in the past with other hvac companies that come out and try and upsell you on everything under the sun. So being referred by somebody that I knew was already a plus and upon checking reviews after being recommended, I thought I would give Cityflow a call. Best decision, the owner Mark showed up and diagnosed the problem fairly quickly and got the job done & being that this was for my parents house and I can't always be there, I got the protection plan they offer as well so in the future my parents can just give him a ring. Definitely found our hvac guy. Thanks again. read more

Mark is a true HVAC professional who takes pride in his work. So much so, that he regularly shares his fixes on his social media because he's not hiding anything and not scared of showing his work (much like the kitchen and chefs being on display to patrons in a high-end restaurant). I'm very fortunate to have found him. I was looking for someone to tune up the old Rheem unit on the new (old) house we purchased. The unit has been working ok but from the looks of the system, it's old, dirty and like everything else in the house, not much was properly maintained before us. I'm not rolling in dough, so prolonging the life of my current old AC was my main objective. Mark cleaned out the condenser coil and found that the evaporator coil was an old z-type where the annual labor involved in cleaning it would be significant enough to merit looking into converting to a conventional A-type coil. The simplicity of the conventional design would mean reduced annual maintenance costs and would also make the system run more efficient (being a new coil, it'd also flow better). So glad we went this route because when he took the old coil out, it was corroded and had mold all over it - yikes. Mark also put on a hard-start kit on the condenser to smooth out the power draw when the system starts up and replaced the contactor. The lower the stress and run time on the AC system, the better my odds of squeezing a few more seasons. Mark did offer a few solutions but when I told him I wanted to take a few extra steps to increase the odds of making this 25+ year-old system last a few more years, these were his recommendations. I'm not a professional but I do have some general knowledge on how these things work and his recommendations made sense. All that being said, his prices were fair and the conversion and fixes he did looked very clean. I really enjoy when a professional shows me everything he did - it means there's nothing to hide and he stands by his work. He showed me some of the work he did on his social media and how he interacts with other HVAC pros - it's obvious that he takes great pride in his craft. If you're looking for the cheapest mickey-mouse solution to your HVAC problems or you're looking for the cheapest install on a new system, go somewhere else. But if you want something done right, whether you only have the funds to squeeze by for the season or you want a new system or somewhere between, Mark will find a solution for you and it will be a fair price. read more

Our heater has been acting funky, and with family coming in for the holidays we needed it fixed ASAP. I contacted Mark from Cityflow on Thursday night and he was at my house by Friday afternoon. Scheduling was super easy on yelp and he was super responsive and punctual, giving me updates on his ETA and arrived exactly within his scheduled window (rare these days!). Once here, he took a thorough look at my heating panel and told me it seemed like the heater wasn't communicating with the panel, and that it might be a matter of replacing it. However, he wanted to check one more thing just in case it was a simpler fix. Thank god he did because it turns out it was a simple matter of our heater's sensor being dirty. He cleaned it and it works like a charm now. Great guy, very knowledgable and doesn't try to rip you off. We have definitely found our HVAC guy! read more

Let me just start off by saying not only is Mark an amazing technition he is also a super nice a just plain solid dude. No B.S. No Upsell. No take it or leave it attitude like other techs. I have so many wonderful things to say about Mark I don't even know where to start. At the beginning I guess - I originally called Mark to help me work on an old central air system I have that was badly designed and installed. Something that already came with the house. Mark was really amazing in helping me try to find a good affordable way tweak the system and re-duct it to make it operate more efficiently. I had several techs at this point looking at the system and all just wanted to rip it out and put in a whole new system at a cost of over 15k. Mark was the only tech to actually try to figure out how to make what I have work better. Things like increasing the return size and changing some line layouts. Even the way he was suggesting to increase the return size was creative in a way no other tech was even willing to consider. If anyone has dealt with a lot of techs they know that even trying to suggest a different or creative approach with them is folly. Almost every single tech I've ever dealt with has an "I know everything" attitude and a "it has to done this way" response to any question about why a job is so complicated or expensive to just replace a ball valve? BUT Mark not only listened to my questions and ideas and didn't make me feel stupid for trying to find a way to save myelf money but he considered them and tried to find a way to make my ideas work. For me that's an unheard of quality in the trades of any sort. So after all that we came up with a plan but after crunching the numbers and considering alternate options it still just didn't make financial since for me as I could just put in a mini split system to solve my trouble areas. I had already considered that as an option so I already had a couple quotes but Mark still came in cheaper for the EXACT system I wanted. I had a couple other cheaper quotes but it was for a cheap Chinese knock-off system. Once again I told Mark the system I wanted and he didn't even flinch. He did offer some options but gave zero push back on getting the exact system I wanted. AGAIN - every other tech would say, "no you don't want that" or "that's not really a good system" and then only offered the system THEY wanted to sell. I'm no dummy. I research everything and don't ask a question or for a specific product unless I already know the answer or that it's top of the line. It helps me guage whether a tech is honest or not. Mark was straight with me every step of the way. Anyway to get on with it - Mark installed my minisplit system easy peasy. We had one technical hiccup of the line covers not fitting quite right. I wasn't happy with the fit and Mark came back immediately to redo them and order new larger parts for a better fit even though they weren't part of the original kit. He did this without charging for the parts. He just did it to get it right. For anyone thinking "yeah that should be the way it's done", you're right. But people seldom do the right thing anymore. I was pleasantly surprised to not get some lame excuse and a bill for additional parts. So all was well and my system has been functioning perfectly for the last year until yesterday ---- So seemingly by just random chance my system just died. In the middle of crazy of a heat wave. No power. It just died. After messing around with breakers and stuff I called Mark. At this point it was around 6pm but I got a call back immediately. I think he was still eating dinner but called me back anyway! He tried to help me trouble shoot it by facetime for a while but after a few minutes it was obvious I was in over my head. So he told me to just leave it be and he was coming right over. That Night.... NIGHT!!! Luckily he lives fairly close to me so I think that made it easier but still... The dude was practically still chewing his dinner when got to my place. It took him all of 5 minutes to figure it was just a blow fuse and replace it. NO CHARGE because I was still under warranty. Even with the warranty he didn't have to come over immediately but said he didn't want my wife and kids to suffer the heat the next day. Now that's the right way to treat a customer but seriously - how often do we say, "people just don't care anymore" or "what happened to customer service?" You just don't expect people to do the right thing anymore but apparently Mark didn't get that memo and just keeps on being a good guy. There is no one I could recommend more strongly than Mark at Cityflow. He's a solid dude and great tech. You won't regret calling him and you'll be hard pressed to keep from having the guy over for some beers afterward. Just a great guy. read more
