I can't speak for the other reviews but I recently had an amazing experience with SD Air I had been having problems with my furnace and overall home heating. I had a company come out, charge me $100 to give me their recommendation on what was wrong, and basically told me I needed a completely new system for $10k I wanted a second opinion and reached out to Mark with SD Air and he came out two hours later to look everything over- no charge He explained, in ways I could understand, everything that was wrong and repeated himself as often as I needed for me to fully get it. He had no problem with me asking a lot of questions. He showed me what he was doing along the way and showed me personally the problems as he was fixing them. He found a much better solution that would only cost me $2100! And it worked! The entire system has worked better than it ever has since being in this house. I only wish I had called them sooner He was also so patient and amazing with my very curious 17m old read more

We were glad to find Mark Slattery from SDAir, an HVAC company located in Pacific Beach, after our nightmare with Mauzy Heating and Air regarding our broken HVAC system (see my previous review about Mauzy). We communicated at length with Mark and informed him of the unfair situation Mauzy had placed us in regarding Mauzy's error that caused the warranty of our HVAC system (which was initially installed by Mauzy) to prematurely expire which then prevented us from getting our broken HVAC system repaired under warranty. We also informed Mark of Mauzy's steadfast unwillingness to right their wrong even though we've been a repeat customer of Mauzy, having spent over $19,000.00 with their company. Mark sounded knowledgeable, experienced, and he assured us that he could get our two broken Fujitsu mini split A/C & heater wall units covered under warranty (just the cost of the parts but understandably not the cost of labor) because we had evidence to prove that Mauzy was in the wrong and had filed the incorrect warranty start date of our HVAC system with the Fujitsu distributor. After having been burnt by Mauzy we were extra cautious but our communications with Mark, and subsequently meeting with him in person, left us with a good feeling so we gave his company a chance. Mark promptly gathered evidence to provide to Fujitsu, which demonstrated that Mauzy had in fact filed the incorrect warranty start date for our Fujitsu HVAC system with the distributor. Then he initiated contact with Fujitsu and after reviewing the evidence, Fujitsu agreed to cover the entire cost of the parts under warranty. The parts arrived in a timely manner and it took Mark and one of his staff an entire workday to complete the extensive repairs but we're happy to say that our two broken A/C & heater wall units are now in perfect working order. We appreciate that Mark and his staff were professional, efficient, and true to their word. Although we understandably had to pay for the cost of labor for the repairs, Mark's ability to get Fujitsu to completely cover the cost of the parts under warranty saved us $1,500.00 from what Mauzy wanted to charge us for the repairs. We highly recommend Mark from SDAir for HVAC needs and we wouldn't hesitate to use him again.

I recently had 2 HVAC companies come out to look at why my heater was tripping my breaker. Both companies informed me that I would need a new water chilled heater and would run $7000 for new unit and install. SD Air and Mark were my third call and so thankful. It turned out that my breaker wiring was old on the main reason why the heater was tripping it. He replaced what was needed, explained in detail, was responsive and I have now saved considerable amount of money. Highly recommended, I felt Mark was honest and that is hard to find.

All I can say is I'm so thankful about finding this company. Not only are they reliable and on time but they fixed our problem. A lot of companies downtown talk about knowing all about HVAC units, take your 99 bucks for a "diagnostic visit"and come up with no answers. If you live downtown, call them! The job will actually get done and you wont end up with a quote for new equipment instead of a repair job. read more

My home office heater would not fire up, the thermostat would click but nothing happened after that. Two other companies took a quick look at it and said to replace it with an expensive new unit. When I emailed Mark of SD Air, he said he had an opening the next day. He arrived right on time with his son, ran a number of tests, did some repair work on wires, etc, and now the wall heater is back and working great. Mark called in advance to let me know he was were on the way, and he and his son were great to work with. Total cost was about a tenth of what those other companies would have charged for a replacement! I would definitely recommend Mark and SD Air. read more

Mark did an excellent job installing my Trane Condenser for my condo today. My 13 year old compressor went out last year and I decided to swap out the entire condenser rather then fixing the faulty part since the price is roughly the same. Mark was able to offer me the best deal in town AND was able to install the very next day! I've spoken with many other HVAC companies but Mark really knew his stuff and took the time to explain everything to me along his diagnosis and installation. His soldering skills are amazing and I am sure my unit will last longer then my last Trane unit. Ignore those select few one star ratings, SDair was professional, arrived on time, installed my equipment quickly and safely along with setting a new standard in what I expect from any HVAC services in the future. I would highly recommend SDair to anyone looking for excellent service and the best deal in town. read more

Mark and his team are the best. Had a problem in my new home and he was able to diagnose the problem and get it fixed when other companies in the area couldn't even figure out the problem. Wouldn't call anyone else! My AC and heat team for life. read more

I've been using Mark Slattery and SDAir for several years now but unfortunately for Mark our relationship has come to an end. If you are reading this, you too, would be wise to look elsewhere for your heating and AC needs. Mark does good work and he is reasonably priced but he simply cannot be relied upon to turn up on time...if he turns up at all. I know at this time of year he is very busy and I understand that and I can work with that....I'm a reasonable guy. People have emergencies and there is more pressing work that needs to come before mine, I get it. What I struggle with, is that I'll make an appt a few days out and he still fails to show. I've planned my day around this appt and he DOESN'T even have the courtesy to let me know he's running late or unable to make the agreed time. He has my number and yet he FAILS to take the 15 seconds to send me a text message. What the heck is up with that? This is not a one time issue, this has happened with Mark MULTIPLE times. I have sent a LOT of business to Mark and SDAir over the years, but I have had enough. I no longer recommend Mark Slattery and SDAir and I will no longer refer my friends to him. read more

Mark and SDair are horrible! Mark confirmed an appointment, said he was getting parts, I follow up and he said "I'm on the way" and he NEVER showed up! EVER! And then didn't return phone calls. One star is too many for this company, From my opinion this is the kind of company that creates the bad reputation for small service businesses. They should be put out of business by the BBB or someone. DO NOT CALL THEM! Go elsewhere. The good people at Hi-Tech Air and ASI were much more helpful! read more

SD Air, What can be said about this company? Superb pricing, responsive and caring professional service, excellent responsiveness and timeliness, excellent products and results are a few adjectives that describe my experiences with them. Two years ago I had SD Air do an install for a furnace that needed to be replaced. They exceeded my expectations by providing a great recommendation for an efficient and well-priced furnace optimized for my home's square footage. They installed the unit in less than one day, while removing the old unit and cleaning up after the work was complete. I was extremely happy with the furnace install and pricing. Additionally they completed the job while I was away on business; this is a company you can trust! Two years later, I decided to add an air conditioning unit to my home. Before calling SD Air I received a few quotes from other air conditioning companies in the local area. My install was during summer peak season causing many air conditioning companies to be extremely busy; many had little time to even provide an estimate or accommodate my busy work schedule. Mark, the owner, and his team showed up the day after I called, flexing to my schedule, and provided a very reasonable estimate. After proceeding with the installation the estimate ended up being extremely accurate. When setting up the installation date, again SD Air was very flexible and worked around my schedule, which wasn't easy since I was in and out of the area around that time. During the install Mark and his team arrived promptly, and were very courteous while taking the time to explain the details of exactly how the install would proceed. I was impressed that they finished the entire install within a half day's time. Not only did they tackle the complexity of my small attic space with ease, they completed the entire install without a trace of mess, and took the time to examine the unit with detailed checks and explain the operation of the unit to me. The air conditioning unit they recommended works great, it is a very efficient model and is an excellent fit for the square footage of my home. With the multiple detailed conversations that Mark had with us I can tell he is very experienced in the field and would give great advice on air service for any install. I usually do not make Yelp reviews however, I felt compelled due to the professionalism, timeliness, reasonable pricing and overall knowledge displayed by SD Air during my two separate installations. I will highly recommend SD Air to anyone of my friends or colleges and I hope this review will help you consider this company for your install. read more

Mark is very skilled at his job and I would recommend him and sd air to anyone in need of repair, install etc. Keep up the great work! read more

Mark did an excellent job. He explained what he was going to do, why he was doing it, and what we could expect along with what those next steps would be. This made us feel apart of the repair, made us feel comfortable with his service. Another person had suggested replacing the entire hvac system which would have been a few thousand, but with Mark's knowledge, he reviewed the system, explained what he was going to do and how this would fix it. Said the system was in excellent shape, no need to replace. And in the end, he was right the entire time. If you need a system looked at, have Mark stop by, you won't be sorry. read more

It is important that I revise my February review and compliment Mark at SD AIR for going above and beyond what would be the normal service call, especially during this summer heat wave, and finding time to fit us into his busy schedule. Mark came with an open attitude and throughly inspected all the equipment which was working perfectly and afterwards confirmed that the temperature issue was directly related to the internal construction that was restricting the air flow to the upper floor. He even called the ac manufacturer to ensure that all updates were current. After the inspection, Mark sat with me and discussed possible options to improve air flow, again going beyond what was a normal service call. Thank You taking the time and effort it took out of your schedule to inspect and perform service, you truly deserve your 5 star rating for quality and service. Ray read more

DO NOT TRUST MARK! Asked him to come and check out m split AC unit. He came and immediately, without approval started to remove the refrigerant from my system and didn't inform me he was doing or asked for approval. Further, after working on the system he billed me for a "diagnostic charge" of $89 in addition to his "labor" to make some minor adjustments. When I started getting alarms that there was an issue with the system via the controller, he said he wasn't responsible for the controller despite it indicating there was an issue. More importantly, he informed us in writing that we would not have to pay him despite his promise, in writing, that if he didn't repair the system and return it to normal operation we wouldn't owe him anything. Based upon my experience, I would avoid SDAIR! There are far more reputable companies who are responsible and do as they contractually agree. read more

It was my lucky day when I met Mark and Mike of SDAIR. They were professional, helpful, and honest - three items it is hard to find out there in the repair world of furnaces and air conditioners. As a senior, it was s comforting to find someone who cared about our age and our financial situation. I would recommend them highly -particularly ifr you want service, honesty and good products. This is my first time to wrote an opinion on YELP, but simpy culd not let a chance go by to let others know how great SDAIR is and won't hesitate to call on them with any future needs.

He was 5 star at one time! I've had two jobs done by Mark. Both jobs were about $9,000 total. The second one involved a pump which was defective. He told me we were waiting for a new pump for over 2 months. I wouldn't care about waiting but the noise was horrific when it would turn on. Anyways I apparently sent him an email where he didn't like my "tone" and then he said he wouldn't work with me anymore. I think most people would be frustrated after 2 months of dealing with an issues that has nothing to do with me, you installed it and bought it and identified the product, you fix it. That's why I used you in the first place. HUGE LACK OF INTEGRITY. Now I wonder if the item was ever on back order or if he was just lying. If you own your own company and you give your word, you follow through on it and then you have customers for life. But since its summer and SDair is busy, fulfilling a commitment is apparently unimportant. Not to mention it violates your contractor's license and you would lose in court if I wanted to waste time pursuing this issues. I'll just find someone else and you can live knowing your company has lots of 1 star reviews. Update 10/2/2012 ... after some conversations and going back and forth we got the problem resolved. I have the LG higher end wall unit which might have been a bit difficult for them to work with (my guess) and now they installed a new more expensive pump and the problem has been completely fixed. Not a single peep can be heard ... nothing at all. They did have to come a couple times to make tweeks, but we're all good now. read more

DO NOT HIRE THESE GUYS. I'll give you three reasons: 1) They are not licensed contractors as they claim on their website (I know because I checked with the California Contractor's State Licensing Board to file a complaint and theirs is expired). https://www2.cslb.ca.gov/OnlineServices/CheckLicenseII/LicenseDetail.aspx?LicNum=916057 2) They are not bonded. Don't take a chance, if they injure themselves while working on your home, YOU can be sued. 3). If those two reasons don't stop you then I hope my story convinces you. A year ago in July 2012 I had hired sdair.com to find and fix a Freon leak that had been a recurring problem with my AC unit. My unit is about six years old (installed with the new home that was built). Called on a Friday, they were out to my house on Saturday. Mark, one of the co-owners came out looked at the welds outside and determined that the valve that was installed was the cause. He changed out the valve, filled up my AC unit with Freon, pressure tested it, and handed me a bill for close to $1,000. Mark went on to explain how knowledgeable he was and that no one else, even other technicians wouldn't have guessed that the valve was the problem. For the next few days the AC unit stayed cold, and the weather was cooler, so I didn't have to turn on my AC. Well about four months passed and we had a mini heat wave, so I turned on the AC. Nothing but warm air came out. Called sdair.com, scheduled an appointment, they never showed up, nor did they call. I had left various messages. A week passed called sdair again, Mike said he never got the messages. Scheduled another appointment, this time they came, topped off the Freon, said my filters were dirty and that was the cause. The AC blew cold so I was happy. I didn't need to turn on the AC because the weather had changed and it was cooler. Well two months ago we had another mini heat wave. Turned on the AC, blew warm. Called sdair again, this time Mark came out again. Filled it up with Freon, and he said he filled it up with AC seal that should take care of the problem. Well, last month as the heat wave started again called sdair with the same problem, scheduled another appointment for a Friday. I called on Friday morning to confirm and Mike said they will come out that afternoon. Day came and went, no call and no technician. I called them the next day. Mike said their guys got so busy and didn't have time to come out, so we scheduled another appointment for the past Friday, September 4th. I called that morning to confirm with Mike, and he said they are going to be there. Tech from sdair did come, verified I was out of Freon. Pressure checked the lines, no leak, couldn't find anything outside. Mike called and said they needed to go inside the house, but that they wouldn't do it that day, they will come out either Saturday or Monday. No call from Mike regarding Saturday, so I called them. He said they will come out Monday. I called Monday morning, and they said they couldn't come out because they have another install, but said Wednesday is open. I set the appointment for Wednesday. Nobody showed up, nor did they call. Oh did I tell you that I even offered Mike that I was willing to pay half the cost for them to come out and find and fix the leak like they should have done in the first place? I've given up. The only thing I can do is to spread the word through social media and sites like Yelp to prevent these guys from getting any more business. You can also find my complaint with the BBB. For those who gave these guys 4 or 5 stars I wonder if they are just family and friends. UPDATE: Mark immediately left a message on my cell phone after I posted this stating he does have a contractor's license and what I said was false. Okay great, well I will file a complaint with the state licensing board as well. Thanks Mark! Wow the guy is full of BS. My home was built brand new with a brand new HVAC system in 2007. Nor did he EVER show me the leak. He just went ahead and replaced the valve and charged me close to $1K for the work. Did I mention Mark NEVER entered my home to check for leaks using a CPC leak detector? He's more responsive now defending his company than actually doing real work. Check with the BBB, his rating is a dismal D-! I will be also filing a complaint with the California Licensing Board to make sure everyone is aware of sdair. My satisfaction is if I can convince 1 person to not hire him, I am a happy man. read more

Super responsive and efficient. While I had a fairly straightforward job the service I received was top notch. Made suggestions on future work and even told me to wait and do the work later when I would see more bang for the buck. read more

My A/C was repaired on 4/30/12 by http://SDAir.com. I have a Carrier unit that is installed thru the front wall of my condo. It wasn't putting out any cold air. http://SDAIR.com determined that the freon had leaked out of the unit. My unit was not manufactured with a valve that will allow freon to be loaded into it. Therefore, http://SDAIR.com welded on a service valve and loaded the unit with freon. It has been working great. That should be the end of an excellent review---right? Wrong. Over the past few weeks I've noticed that my air conditioner seems really loud from outside of my unit. When I'm inside it's not bad. I understand that big appliances can make a fair amount of noise. So my concern was that perhaps the valve was creating the vibrating noise I hear. Perhaps the valve is touching something. I really don't know. It's still putting out cold air, but it was still a concern. So I called http://SDAIR.com and left 3 messages over a period of a week. They never called me back. I then went on-line and left an email message thru their website. 20 back and forth emails later, the owner (Mark Slattery) refuses to send a tech to my house unless I pay him $79 for a service/diagnostic call. He flatly rejects any notion that the vibrating noise I've described has anything to do with the repairs he made in April. Further than that, he informed me that his company no longer services my particular type of equipment. This alarmed me because my repair came with a 1 year warranty on parts and labor. Of course I told him this and he said he would honor that warranty. I find that hard to believe when he won't even take a step toward my home without me agreeing to pay $79. Going one step further, I asked him this question.... If I agree to your fee and the tech determines that your work is sound but my unit requires some additional repairs/adjustments, will http://SDAIR.com perform the repairs? He said no. His techs don't have any parts for my unit in their trucks and apparently they won't order any. Now, why in the name of heaven does he think I would pay a diagnostic fee for repairs his company refuses to perform? I'm done with http://SDAIR.com. I strongly advise you to avoid http://SDAIR.com. read more

I was at my dads house over the weekend and his ac stopped working. These guys came out and didnt even charge us the emergency fee. They were fast, clean, really polite. It's hard to find a polite contractor. Normally, contractors act like know it alls. NOT these guys. A+ read more

Mark came out to assess and repair our wall heater (pilot wouldn't light) and said he would need to order a part so would be back the next day depending on when he received the part. He took a part from our heater with him to ensure he ordered the correct replacement part...and then never called or came back despite leaving him numerous vm messages. That was over a month ago. We finally called another company (Perry Plumbing and Heating) who came out, ordered the part, and got our heater working again in two days. I agree with the other reviews. Mark is an extremely nice guy but I can't understand taking a part from someone's heater and then never calling or returning to finish the job! read more

I never write reviews, but i had too. excellent, Excellent, EXCELLENT!! I plan on using them again. I called over two dozen other guys and had a 2-3 day out appointment. I needed it done that day by 3pm. I called Mark at 10:30 am. He was at my house by noon. I gave him a deadline because I had a guest. He was very professional. Explained all pricing. Drove miles to get the part I needed and was able to get the job done. No hidden fees, no up charge for my emergency!!! Prices are competitive. Mike his assistant was very nice too. After the job was done he stayed a while to answer additions question and check a few other things too. Great guy. Thanks again Mark. read more

Mark and his crew did a great job installing our new Trane furnace and AC. We talked to him on a Tuesday and were up and running by Thursday. We had gotten several estimates and SDAir was the best of all of them. I do want to mention that SDAir has been our "go to" company since 2012. read more

Great service. Super professional. Very fast service, they got back to me in less than 24 hours of putting in the trouble call. Showed up the next day and diagnosed the problem with my AC right away. Would definitely recommend them and use them again!! read more

Mark made an appointment with me to show two days hence. He called and said he'd be there in 20 minutes. He never called again. He just left his card in the door and left. We were upstairs because my wife is on hospice. This was an emergency condition, and he can't even call my cell? Lousy business sense and service that is self-serving only to him. read more

They failed to show up for two appointments in a row. The guy actually emailed me to say he was on his way to me, eta 30 mins, then nothing. Radio silence. Totally unprofessional and annoying to keep someone waiting around and then just flake. Don't waste your time with this bunch. read more

I had confirmed two different appointments for an estimate. Both times they failed to show up and did not call. I ended up using AirMakers for installation of a new heating and AC system. read more

Our initial experience with Mark was fine. He was quick to respond and really seemed to want our business. However, after he was paid in full and the A/C install was complete, he was unreliable and barely responsive. There were a couple of follow up items that he promised would be done (including the removal of the trash from the install and placing the registers & air filter for our new unit and ducting). It took him more than 2 weeks to come back and pick up the trash that was in our driveway (after he said he would return the following day to complete this task). Also, it has now been 2 months since the initial install and we still have not received the registers or the filter as promised. SD Air's follow up and post-consumer relationship is in need of a huge improvement! read more

One star is too good for these guys. They are unresponsive and irresponsible. They do not return calls or emails. They fail repeatedly to show for appointments that they make. Then when you call to try to confirm an appointment, they claim you are harassing them. They do not want to do any work - just charge for an estimate, the cost of which they claim will be credited against the repair. However, they then refuse to do the repair and you are out the estimate fee." F" rating with the BBB under a different name. Disciplinary action by Contractors State Licensing Board under different name. New name, same story . STAY FAR AWAY FROM THESE GUYS read more

I had a problem with our a/c unit at my restaurant in Point Loma. When I found Mark, he immediately called me back and after a phone consultation, he was at my restaurant fixing the a/c. I mean quickly. I was so impressed with him from the start. He immediately saw the problem of a someone putting on the thermostat incorrectly. When he fixed it, the unit turned on immediately. The next day the unit failed again, in the middle of a very busy dinner time for us, and again, Mark was there in minutes. I feel he is extremely trustworthy and very knowledgeable. most importantly, he really understands customer service. He is top notch. Cant recommend him enough. Go SDAIR! :-) read more

I'm an investor and developer here in san diego and have been dealing with MARK for about 2 years now... top notch service and quality.... its rare you meet someone in my field that does exactly what they say they are going to do and doesn't try to renegotiate a higher price somewhere along the way during the job... MARK has been giving me great prices and consistently, for the past 7 jobs I've used him for. he also is very prompt at returning phone calls or troubleshooting his work over the phone or in person even after his job has been completed. IF ANYONE EVER IS THE MARKET FOR HEATING AND AIR, SAVE YOUR YOURSELF TIME AND MONEY AND JUST CALL MARK. read more

Mark was very helpful and responsive. Helped me get the furnace working in no time.

I had a problem with billing. This company, once they got my money provided the worst customer service I have ever experienced. I would never do business with them again-what a mistake. read more

The a/c in my home stopped blowing cold air so I called Sdair; I was pleased with the service, and the promptness of the company. It was a really hot week last week and I am extremely appreciative my a/c was working :) read more

Don't waste your time with this company. first of all they don't keep apt thus missing work, secondly it seems like they don't know what they are doing. totally irresponsible and inefficient. they don't return calls. ONCE AGAIN DONT WASTE YOUR TIME! read more

We had a very poor experience with this company and do not recommend them at all. They were very responsive initially and seemed to want our business. That quickly changed to becoming unresponsive and they made installations to our heating system that resulted in problems for our tenants (problem wasn't solved). After weeks of unanswered calls and emails they promised to resolve the matter after we had to bring another vendor to cure some of the issues. The other vendor showed us where their installation was poor and not professional in quality. Mark came out to our site finally to inspect and promised a prompt resolution. After another period of weeks of him not providing what was promised, not returning calls or emails he finally responded to say he needed to go back to the site again to check for the very things he supposedly checked on the first visit. He has since fallen off the map. We are usually very accommodating and easy to work with, but this is mind blowing. It seems Mark could care less if his work is poor, if you or your tenants do not have proper heat service, and his customer service is awful. He was emphatic that whatever he did he needed to be paid for and seemed more concerned with making even more money from us than correcting his mistakes. I strongly recommend you avoid this company at all costs. Lessons learned! read more
