My AC stopped working on a hot Friday evening, and Santiago had it up and running by Saturday afternoon. He was so responsive and clear about repair vs. replace options for my older HVAC system. I'd definitely recommend him! read more

Santiago was great! I called when my A/C wasn't pumping out cold air and Santiago came out and inspected the unit the same day. The unit was obviously old and on its last leg and therefore, I needed to get a new unit. I received a reasonable quote and Santiago came out to install my new HVAC system while his partner came to remove the old system component. I am abs satisfied with their work and I would recommend A & K Heating and Air Conditioning to anyone that needs their system serviced! read more

Santiago was able to come out the very next day for our broke HVAC. He took his time diagnosing the problem, was able to locate a part no longer manufactured, and came back the following day to install it. Very easy communication and fair prices! read more

Our AC unit stopped blowing cold air. Had one company come out and tell me the unit was too old to be fixed since it was over 20 years old. I took his word and assumed we were just going to need a new one. I reached out to A&K, through yelp, to get a quote since you can't just have one. Santiago came out same day. He was thorough with his inspection, took his time to diagnose the problem and said he could fix it or give us a quote. We opted to get it fixed for a very reasonable price. He explained and walked us through everything that needed to be done on our unit. I realize we are probably on borrowed time, but my family and I are nice and cold while we make a decision on when to replace. I will definitely be calling him back when we need to. read more

OK seriously this guy is a magician with hot water heaters. Our ignition went down and we have a busy four person household so...we needed that hot water heater fixed pronto! Got a reply and same day visit. He didn't have the integrated igniter unit that our heater uses....so he built one out of the parts he did have! He was clipping metal, wiring, adding bits from the old one so it fit. Amazing. Then when he finished he got a funny look, took out his 'sniffer' for natural gas and found that the tie-in was done incorrectly years ago and was leaking gas. He re-cemented it and checked all over the area and the air unit to make sure it was safe. A truly conscientious person. Highly recommend. read more

A & K was awesome! Very responsive, professional, friendly, and fast. My AC stopped working on a very hot day and Santiago was able to come check it out and fixed it the next day. Very fair pricing too. I'll definitely be working with them again for all of my my future HVAC needs. read more

We had Santiago at A & K replace our HVAC system. He was beyond exceptional. He fit us in during a near-100 degree heatwave. His quote was thorough and competitive. He answered all of our questions. And then we he went above and beyond while doing the install. He even saw that we had some issues outside that could cause damage to our house and just quickly fixed them so we didn't have a problem. Most importantly, our new HVAC system works perfectly. The house is cool, there is no noise at all and the unit is working perfectly. Santiago and A & K are an absolute gem. I highly recommend them. read more

I cannot say enough positive things about Santiago and A&K Heating and Air Conditioning. I will definitely be using him going forward. I called Santiago on Friday about a leak I was experiencing with my air conditioner inside and he offered to come by the next day, on a Saturday morning, to take a look and fix it. The job ended up being more involved than originally expected because of the oddness of my particular HVAC system, but Santiago took it all in stride. I was really impressed by his depth of knowledge and the extent he went to, to make sure the issue was resolved. Whereas others might have just capped the leak and walked away, Santiago tested the system to make sure it wasn't still clogged and discovered that it was, and did some additional work to further ensure the system wasn't clogged so I wouldn't experience the leak again. He also was so mindful of not leaving a mess or having to open up my wall unnecessarily, which I really appreciated. I've had a few folks come out this summer to take a look at my A/C and even service it, and none pointed out the issues Santiago did. Even then, he didn't bad mouth those other companies, which just speaks so highly of his character. Ultimately, I'm a 100% satisfied customer. The time and effort he put into the job meant so much, and I felt the price was good and worth the service he provided. I can't thank him enough! read more

I called A&K Heating and Air Conditioning when my regular HVAC company could not come out to address a leak ... Santiago answered my call, showed genuine concern, and fit me into his schedule same-day ... I texted him details and he texted back right away to confirm. I was beyond grateful. Turns out my regular company was able to help me same-day after all, so I never had the opportunity to work with A&K ... but for sure I will call them again if I am ever in need of a new HVAC expert. Thank you Santiago!! read more

I not one to give 5 star ratings but I can't say enough about A & K Heating and Air Conditioning and Santiago! I requested a few quotes from various companies and A&K came in with a very good price for replacing my 55 year old air handler and thermostat. He came on a Friday for the measurements and on Saturday afternoon I had quote with what was to be included and what was not covered. (I had gotten a quote from another company for over $2000 more and it did not include any information.) On Monday Santiago came and reverified the measurements and by Tuesday evening I had a new air handler and thermostat. I would strongly recommend this company to anyone who wants fast, reliable, trustworthy, friendly service. read more

It was a Saturday afternoon when my AC drain line clogged up. Called about 10 different plumbers before finding A&K. Santiago made time to come right away. Cleared the drain and recommended adding a P-Trap. Great service and fair prices. I will use them again in the future! read more

I have lived in DC proper for over 10 years and have encountered a lot of sub-par service peeps. A & K Heating and Air Conditioning have restored my faith in humanity. They went above and beyond and I'll use them again for sure! Our heat pump went out and I called four companies for bids...one didn't service the area, one guy showed up with a flashlight, one guy told me to send him pictures and never showed, but Santiago from A & K showed up with a ladder and tools...clearly ready to work. He proposed several solutions ahead of replacement including a cleaning and explained in great detail why he reached his conclusions. After working their plan we ended up having to replace the heat pump and the compressor. They knocked it out in a day and while installing they also repaired a few issues from the original installation. Because of their extra attention to detail the temperature in the back of the house is better regulated. The new unit runs like a champ and is quiet. Two days before the install, we also suffered a huge plumbing issue...think a fountain out of your drain...Santiago's partner Ryan came through and fixed that and brought it up to code from the original install (which was not to code, because well the city is terrible). There's also more room under the sink now too. Quick sum...professional attitude, two down to earth easy to get along with dudes, patient and answered every question honestly with options and pros and cons, professional workmanship, pride in work. read more

Santiago just left my home and his service was wonderful. Very very professional courteous and friendly. He was efficient and prompt and let me know what was going on as he was doing each step. He advised me of some things that needed to be changed and I appreciate it as I had no idea. He was in and out within the hour. I would certainly recommend his business and look forward to using his services again in the future read more

Easy to schedule, came on time and was efficient in performing work, would recommend!

Professional and quick to answer any and all questions I had. The the thing that made Santiago exceptional was he answered questions that I wouldn't have known to ask. Reasonable fees, exceptional service he gave me hope in humanity again! Don't hesitate to call. He is honest and trustworthy and that's a difficult thing to find these days! read more

HIGHLY recommend. I recently purchased a new condo and only a few months after moving in my AC quit working. It went out on a Saturday afternoon. I messaged A&K on Saturday evening, Santiago was there on Sunday, and I had the entire unit replaced by end of day Monday. He was great at explaining everything at each step of the way and making sure I knew all the details of my new unit. Very grateful and overall can't recommend enough! read more

I got a number of quotes for A/C service a on Yelp, and A&K was one of them. I checked the ratings of each, and many had mixed reviews. Not A&K. Santiago, the owner, reached out to me, and I called him. I liked what I heard, and he was familiar with the unique HVAC system we have in my condo building. As I described it to him, he asked if I lived in a certain building. He was right. He'd done work here before. So I and a neighbor in my building booked him for the same day. It was only a few days from my contact with Santiago. He showed up, efficiently performed the work we needed, and took photos of before and after and texted them to us. The price was fair for good, honest work. I highly recommend this company. read more

WOW!!! I cannot say enough about A&K. Santiago was amazing from start to finish. We own a condo in DC and rent it out. I am in Texas and when the AC went out I had no idea who to call. Found A&K on yelp and because of all the amazing recs, I hired them. Turns out we needed a new AC unit (ouch). Santiago, knowing it was hot for my tenants, went WAY out of his way to get the new unit and install it the next day. I am so grateful I found A&K...Santiago - if ever you're in Texas, we will cook an amazing brisket!! read more

Santiago is fantastic because he explains everything which I really like. What the problem is and what the solution is. He told me how I could make my heat pump live its longest possible life and his fees are very reasonable. I will use his services for maintenance. He came on the same day I called him and is a very nice guy as well. read more

Our central AC unit stopped working in the middle of a heatwave, and we went through 4 days of contractors not being able to diagnose (no internal roof access), sometimes trying to charge without diagnosing, or, in one case, misdiagnosing a capacitor issue as a compressor issue which would mean long time to fix and thousands of dollars in costs. Needless to say, we were at our wits end. On Day 4, I contacted Santiago, who decided to come diagnose the issue himself, came early and found that the issue was a capacitor. He changed the capacitor and the issue was fixed immediately. This saved us weeks of waiting for compressor parts we did not need and thousands of dollars in costs. It is sometimes hard to find honest contractors but Santiago was one of them. He also explained all the issues well and took lots of pictures. Please give this company your business!! read more

A&K earned our business because they responded quickly using Yelp and text and got out to us the very next day. The reason our HVAC system went down ended up being a relatively easy fix and their price was reasonable. read more

Santiago did a great job for us back in November when our heating system failed. He did such a good job we decided to bring him in this spring for an air conditioner preseason tuneup. We have used other companies which promote "Spring tune-up special deals" for this task in the past and it was a waste of $ - all they did was quickly gloss over the equipment and say everything looks ok. Santiago took his time and was very detailed both with the inside unit and the compressor (which was filthy and in need of a thorough cleaning). Santiago did it all. Yeah, it was a bit more $$ than one of the "specials" but VERY worth it. He's also very prompt and courteous - a very nice guy! read more

Immediate service. Thorough, honest and personable. Reasonable price. Would use again. A real find!

Santiago came by to look at what we thought was only a blocked furnace exhaust. Long story short, Santiago identified a very serious issue with the unit that could have caused co2 and also a fire. We needed to have the unit replaced as it was badly damaged by water and also was 22 years old. Santiago arrived on time the next day and took care of the install. Throughout the entire process Santiago was the most polite and professional individual I have worked with in a long time. His experience and commitment to his profession show. I felt like I had a friend doing the work, not someone I just met. Whatever your HVAC needs give A and K a call. Professional, courteous and very thorough. I will definitely give them a call for any future needs. They are truly a 5 star business. read more

My hot water heater pilot light was not going on and Santiago did a wonderful job of making the repair and letting me know what was wrong. He was great to work with. Highly recommended. read more

I would strongly recommend Santiago. He is honest and very easy to work with. It is easy to schedule with him and he keeps his appointment times. He also does a great job of explaining the issues with your HVAC units and what needs to be done right away versus can wait - I appreciate that level of professionalism. read more

Santiago was great to work with, very professional and friendly. He was efficient and prompt and let me know what was going on as he was doing each step. Serviced and cleaned my HVAC system and took pictures before and after. Would hire again and recommended to anyone wanting their HVAC system inspected and cleaned. He also provides service for water heaters. read more

A & K Heating and Air is fantastic. After our AC went out last night, I contacted A & K this morning and Santiago got right back to me, and he was able to come same-day. He diagnosed what ended up being a tricky problem in our old DC row house, and he got the problem fixed quickly and for a very reasonable price. It's hard to find a good HVAC service person in this city--I've tried and tried for years. Santiago is legit and trustworthy. Highly, highly recommend. read more

I called Santiago about my old HVAC unit. After determining that the unit needed to be replaced, he planned out the project and did a great job with the prompt install. More importantly, we had two call-backs since the install and Santiago was a consummate professional. He found the cause of the issue, explained the problem and maintained a positive attitude throughout the interaction. If you live in the Gaithersburg/Rockville area and need help with HVAC, please give this man a call. 100% satisfied. read more

A&K Heating and Air Conditioning is nothing less then incredible! I called them out not to long ago because my furnace would turn on but will not fire to produce any heat.Unlike every other HVAC company you find on google that you're afraid to call to your home because of there ridiculous prices...these guys are the complete opposite...Your issue will be solved with the best customer service in town.Santiago does a great job communicating what's needed for your system to work now , near & far future.I still can't believe the deal and breaks I got on getting a whole new furnace and if I wasn't hard headed and listened to him last year when he first visited my house I would have saved so much l money on my utility bills.I'm telling you guys I can't stress it enough how good this company has been to me and I'm sure to others.Don't look any further! I am confident I have a permanent HVAC company as long as I'm a home owner. read more

A & K Heating and Air Conditioning - New Install - Heating & Air Conditioning/HVAC Near Me

We trust Santiago to take care of all our heating and air conditioning needs. He's super efficient, knowledgeable, friendly, and actually came on a Sunday to make sure our needs were taken care of! The last company that came to help us stayed about 10 minutes to check out our system. Santiago spent so much time cleaning our air conditioning unit and explaining everything he was doing and taking before, and after pictures to show us and giving us advice for potentially changing our set up in the basement. Money totally well spent! If there were more stars available. we would give him 10 stars! read more

When you need quality HVAC work from an honest company that stands behind their work, make sure you give A&K a call. My system was giving me major headaches and A&K was able to both troubleshoot and resolve my issue. I can't recommend them enough! read more

I live in Sarasota FL. My property manager for my rental in Washington DC arranged for the replacement of our boiler. She had very favorable comments about Santiago: "Santiago explains everything that needs to be done.  Shows up on time and is always concerned about safety and making sure everything is up to code." I spoke to Santiago a couple of times on the phone, and he sounds very knowledgeable and courteous. He promptly sent me photos of the finished job. We are pleased with the service and the quality of work, and would highly recommend him. - Sheila read more

Great service....very responsive and very reasonable price wise. Highly recommend!!!! Thanks Santiago!!!

100% satisfied. Outstanding customer service provided by Mr. Trejo. He gave me sound advice for preparing my home for an extended unoccupied duration. Friendly and knowledgeable. Absolutely recommend this company for your heating and AC requirements. I will definitely use his company again in the future. read more

Santiago is AMAZING! He replaced our AC in 24 hours during a heat wave. He responded to me immediately and was available to take a look at the problem the same day. He worked so hard to get this done for us and I can't express to you how rare it's been to find someone as old school and awesome like him. I called so many other businesses before I called Santiago and everyone turned me down. He was the only one who was able to help me out. He's experienced, fair and honest. I will always call him first and recommend him to all my friends! THANK YOU! read more

My AC cut off on Sunday morning; and my regular HVAC technician was out of town; he had A & K service my AC and the technician came out immediately in all the heat to take care of the problem with my air handler which was in the attic. We are talking about the one of the hottest days. He diligently worked on the problem and thank God, he was bale to get me air in my home. I truly appreciate his consistent and unwavering effort to see that I had coolness restored in my home,especially since I am a senior citizen. July 30,2020 Thank you Rosemary Latney read more
