So glad I called ACE Heating & Air-Conditioning! I called at 9 AM, Quenten was here by 1 PM, and I had cool air again by 2 PM. I was really happy to have my annual maintenance plan -- my repair was prioritized and I didn't have any out-of-pocket cost. Quenten was awesome: friendly, knowledgeable and he kept everything clean while he worked. Great service from a family-owned business. I highly recommend ACE! read more

In the last 5-7 years, we have had at least 5 new HVAC units installed by ACE. Of course, there have been bumps in the road - usually they did at least try to make it right. Not anymore and I strongly advise everyone to avoid them that (although I previously used to heavily recommend them) I will now be certain to use every platform available to share our experience. Throughout the summer, I called to schedule an appointment and was repeatedly told they were many weeks, if not months, backed up but I could call for cancellations. All this time, I let them know that the unit was dripping on the floor even though we had cleaned the condensation line. By September, it was dripping so much that it was damaging the hardwood floors. On September 19th, I finally got an appointment - in December (as they said they were booked up past Thanksgiving.) Waiting a week or two, or even three, is manageable. Waiting three months is unacceptable. Shortly after making that appointment, I called another company - and they came out within a week. We are now looking at needing a completely new system when we didn't even get 5 years out of this one. The new techs told us it was installed incorrectly - thus straining the system. I tried to give ACE the opportunity to make it right - at the very least, they could have apologized - if not given me a (small) discount on a new system. I understand people make mistakes and I wasn't looking for thousands of dollars. Instead, they blamed us for not getting routine maintenance - when the unit is managed by someone with a certification in property management and was routinely maintained... we had called them that time (as we had in the past) because it was a significant issue beyond routine care. They called me back to let me know they thought we should "kinda part ways." So, in addition to needing a new 11k system just 5 years after buying one from them, I now have 10k in hardwood floor damage as well. What they should have done from the start was told me it was best to "kinda part ways" when I initially called and was staying loyal while trying to get them to come out for most of the summer. Never again - I understand the system is no longer under warranty but it should have been installed correctly and it shouldn't take months to get a technician out in an emergency. read more

Ace Air Conditioning & Heating Service - Heating & Air Conditioning/HVAC Near Me - Chantilly, Virginia

I had a phenomenal experience with Ace, with Cory as the person who came to help! He was so incredibly knowledgeable (showing me step by step what he's working through) and courteous (ensuring my home stays clean by wearing protective covers), and he was able to get my system back up and running at an incredible value. Originally when my AC system started showing problems, I had gone with another company who sent a tech over and they spent maybe 30 minutes looking at my system and immediately told me that I needed a new HVAC for several thousands of dollars, and when that tech left, my home got exponentially hotter (mind you it was 98F degrees that day). I immediately called Ace for a second opinion after looking online for well-rated service providers, and Cory came by the same day, went through a thorough diagnostic review, and even discovered that the previous tech from the other company turned off my AC! (Benefit of the doubt: it could've been by accident and not malicious, but at best, it was negligent.) Cory was incredibly persistent in finding out what was wrong, and fixing up my home's system so that it's running like a dream. My whole experience was fantastic and I have highly recommended them to all my friends and family, and will continue to highly recommend Ace! read more

ACE is fantastic. The tech Quenten is a star. He always explains everything and is thorough and reliable. Quenten is 5*. Thank you ACE

Ricky came out by himself to diagnose my issue with the AC not working. He was thorough and did several tests. He asked a lot of pertinent questions to troubleshoot. He is clearly knowledgeable and also very personable. Highly recommended! Thank you, Ricky! You da man! read more

Ricky and Douglas were here today to install a new Lennox air conditioner and we couldn't be more satisfied with the job. We would recommend this company to anyone. Also very impressed with talking to Courtney and Jonathan in the office. Thanks for a job well done. read more

Ricky and John were terrific. They called ahead to say when they would be here, they were courteous and went right to work and were extremely efficient and knowledgeable. Absolutely recommend! read more

We have used Ace Air Conditioning & Heating Service for the past eight years and they have consistently been wonderful. Their office team is very helpful in scheduling appointments, sending reminders, and letting us know what time the technician(s) will be arriving. The technicians are great. We had a new HVAC unit installed in July and they provided an accurate estimate in advance and guided us through what the purchase elements were and how they sized the estimate. The new system is great (especially given the recent 90+ degree weather.) The entire Ace team is professional, courteous, and are just great people to work with. Highly recommend them!! read more

This was my wife's and my year to replace an AC compressor and yesterday a 12-year-old hot water heater. Needless to say: having ACE do the replacement of this equipment took the worry out of getting the job done right. If you are looking for an AC and Heating company to take care of those needs in your home; you can do no better than ACE. Don't forget those yearly contracts that ensure prompt service when you need it. John K Nusbaum Reston read more

Do not be fooled by this company! I rarely write a review let alone a bad one! Their tech came to diagnose why furnace wasn't working, he left a mess with wires out and hanging, did not put anything back in place. I had another guy looking at it for second opinion, the same part they said needs a replacement was quoted with $1000 price difference!! I talked to Jim, the manager, asked him about the mess his tech left and why such a big discrepancy, his response was he didn't know what I wanted him to do!! He wouldn't reveal who owns the company as well. He said everything is on him!!! Use another company! Update.. Jim left a message that they'd fix my furnace at no charge and he was very professional over the phone. Told him not too many businesses deal with complaints like this the way they handled my situation. and that I appreciated their professionalism. I am changing my 1 star to 5! read more

Looks like more problems came up while I was either away at work today or whilst I was out on holiday this past week. Outside condensing unit doesn't turn on yet inside air exchanger, that is set on ~74* has not stopped and the thermostat has not gone lower than 81*. The air exchanger has not turned off the last hour. Emailed ACE and hope to get an answer asap. read more

I used ACE to install a new Lennox HVAC unit in 2016 for our three level townhouse in Falls Church. It wasn't the most expensive unit, but it was a nice one that had some 'smart' innovative features. While it worked decently well for the first two years, we started having issues with the AC not cooling our home in 2019. We had ACE come out several times and seemed to fix the issues, but after a few days, it would go back to not cooling properly. Eventually I was running out of patients and tired of our home being 5-10 degrees warmer than the outside temp. As Spring transitioned to Summer this year (2020), I escalated my concerns and frustration to Neal in ACE's office. He reviewed my customer records and agreed that what we were experiencing was unacceptable. He committed to fixing the issues permanently at no cost to us. It took a couple of diagnostic and repair visits, but he followed through 100% with his commitment and didn't charge us a penny. Our home has never been this cool and comfortable during the summer, and it's been so nice given the 95-100 degree days we've had this year. It is wonderful to work with a company that stands behind their work. I ABSOLUTELY recommend ACE to anyone looking for help with their heating and air conditioning needs! read more

We had a great experience with ACE purchasing a new HVAC system recently. From their proposal & quote, to installation and then a follow up issue - all handled promptly, professionally & pleasantly. Kevin, Ricky and others worked hard to get our business and then handled all aspects - installation was impressive - along with our many questions. We have only good things to say about ACE - their quote was more attractive and detailed than several other firms. This was our second time using ACE. 14 years ago we used them for an AC purchase and were happy. After many years, our experience as a "new" customer this month was even better! read more

I had a full house plumbing inspection on March 10th, 2023 and I was so impressed with the technician and his concern and knowledge for my home system and my questions. Very through and professional! He even helped me with a personal problem I had that was most appreciated!! The technician's name was Anthony Burro. I would highly recommend him and ACE for your heating cooling plumbing needs! I had a new A/C heat pump package unit installed a year ago and it looks and works top-notch!! read more

This is company is amazing. We had a gas leak in our home, they arrived in minutes of my call! They are very reasonable priced, extremely clean, and very polite. Wonderful to work with. I highly recommend this company. read more

He came out to provide a quote on a new system (after our heat pump failed), and never actually sent it to me. It's been 2 weeks. EDIT: It was a simple misunderstanding, and I now have it. All is well. read more

Our A/C went out and ACE gave us a competitive quote. We went with them and are so glad we did! Technicians, Douglas and Ricky, were polite, friendly and professional. They maintained a clean work environment and answered any questions I had. They also helped identify a leak in my roof - beyond their focus in my attic - but so appreciated. Definitely request Douglas and Ricky at ACE if you are getting a new A/C!! read more

We just had our old system replaced after 18 years and we are very happy. The previous system was purchased through ACE 18 years ago and it ran well. But, after 18 years, it was time for a replacement. We have been with ACE since we bought our last system. The home's previous owner was also with ACE and she was very happy. During the past 18 years we have purchased their annual service contract. The great thing about this is that it puts you at the front of the line if there is a problem. They made it out to our house with in 24 hours both times we needed to use it during that 18 year period. I have always found ACE and all of its staff to be the consummate professionals. They make sure they keep the house clean, are very respectful and explain everything thoroughly so that we can understand everything that is going on. When we new we needed a new system we got three different quotes. ACE was very competitive and easy to work with to set everything up. The installation of my new system (which occurred this week), was no different than my other experiences with ACE . Jonathan and Ricky were our installers. Again, they were the consummate professionals I expect from ACE. The other thing about ACE is that they do not cut corners. They take their time and make sure everything is done to factory specs. After researching other companies, it has become clear not every company takes the time to do everything right. I would recommend ACE to anyone with an HVAC issue. They are competitive, reputable, reliable and most importantly--ethical! read more

My 15 year-old water heater broke and I got estimates from 4 contractors. Ace was the 2nd most competitive price. Kevin was very responsive over email answered all my questions. JR did the estimate. And Wilme and Michael did the installation. They were on-time and did good installation -- everything up to code including the drain pan and expansion tank which I didn't know about. I would use them again. read more

For routine spring tune up of a properly functioning system, they seemed competent (I've used them twice now). The technician seemed to think my system was in good shape and reassured me that it would last for a long time and be inexpensive to repair if it ever needs it. The technician told me his "life story" and mentioned his reliance on tips to make ends meet within a couple of minutes of entering my home, but mentioned it wasn't obligatory. Had he not gone there, he might have actually gotten a tip. Polite and pleasant enough guy but that approach was poorly executed. Ace's ability to predict what time they would come was poor. Initially they said after 1. I called around 12:30 to say I was home and get a better estimate, and I was told between 2-4. At 3:30 a technician called and said he would be there in an hour. At 4 the office called to say I was switched to a different tech and it would be after 5. Once I was actually the next stop, I got a text, an email and a call from the technician with an accurate ETA - great! However the technician finally showed up at 7:10. Not exactly between 2-4. read more

Ace just installed a new water heater for us today. I called yesterday in a panic because the unit was leaking on the floor and did not know how to stop the water. I actually called probably 8 times and talked to Sean, the office manager each time. He was not only so helpful each time but he was very patient with me. When I called him on Tuesday he said he could do an install on Friday and then when I called him back he said they had a cancellation and they installed the very next day, Wednesday! IT was a pretty labor intensive job with many pipes that had to be cut and it was a power vent install that added to the complexity and time. The two guys that came over worked very efficiently. They even did a Winter Inspection on my furnace! The only complaint (if I had to give a complaint) is that I told them to keep my laundry room door closed because we have so many chipmunks that hang out right at that door and they left it open when they were taking the old tank out. Oh one more minor complaint, when I went down to inspect the work, I asked for the manual so I could file it away and the worker said it is on the unit and if I needed it I could get it. I asked him to get it and he could not reach it because it was in the back of the unit in a tight space. Maybe it is just me, but I do like to keep all my owner manuals in a file if I need it. Sean is working on getting me a new AO Smith Owners Manual. I have been using ACE for the last maybe 11 years, they installed our furnace several years ago. Very very impressed with their service and would highly recommend them. read more

The technician who came to our house was friendly and efficient, and our humidifier now seems to be back in working order (all that it needed was an air filter swap - d'oh). That said, this review is mostly for the admin staff/logistics, which could use some improvement. I tried to call to make an appointment but there was no answer, so I used their online form instead. After emailing with them, I was told to call the company the next day to get a timeframe for when the technician would come. I wrote back and asked if they could please email or call me directly instead with that information (seemed a small thing to ask, I thought - I asked because I knew I'd be busy in the morning and not able to call). The woman said that was fine, and also asked I provide a phone number, which I did. The next morning, I never heard from them (email or phone), the technician showed up with no notice, and when he arrived, he said he had never been given my phone number. I was also disappointed because I asked the technician if he would take a quick glance at our furnace while looking at the humidifier, just to make sure it was okay (we aren't sure how old it is), and he said he didn't have time (his whole visit, which cost me $110 + $35 to replace the filter, took only 10 minutes... so it's not like he'd just spent hours looking at our humidifier). All this said, I would probably go with someone else next time. EDITED TO ADD: After seeing this review, the company reached out to me about having a complementary follow up check up service to make things right. I was impressed they made the effort and the technician who came was great - took his time explaining what he was doing and seemed very knowledgeable. Upgrading them from 3 to 4 stars. read more

This is a quick letter for Neal's recognition for excellent service. On 23 Jan, 2013, when temps were in the mid-teens to very low 20's as daily high temps, ACE was called for service to the installed Carrier unit that went out but went into a mode pumping low volume "heated air". The next day Neal happend to be the technician who installed this masterpiece that has served the home well. Due in entirety on the failure to maintain regular filter replacement, it was packed and gave the system more resistance than normal, setting the entire electronics in a fit. Neal was on his daily route PLUS emergency calls from 7AM and responded here at around 6:45PM and had more jobs after he left at about 8PM. The level of professional service he reflected on the company as well as his in-depth knowledge of the complicated system (to me) was evident in his quick diagnosics, probabilities of issues vs others and intelligently resolving the issue. I am very satisfied with Neal's professionalism, technical depth of knowledge and accurate resolution! He also recommended a whole house humidifier as he was alerted by the very low 17% humidity in the home, add the fire I had going, there was a dire need of this system to be put in place! An order was placed on the spot for a steam humidifier with out a second thought. Thank YOU Neal, keep up the good work. ACE is very FORTUNATE to have a professional as your self on staff!!! I will happily refer you to all in need. Regards, P. Himes read more

Last summer our A/C went kaput and the ACE techs were out in no time investigating the issue - they didn't try to sell me a new unit - they just saw it was a simple part and they replaced it rapidly at a low cost. Then our old furnace (15+ years) cracked this past winter and we had a quality replacement installed in no time by them as well. Their techs were fantastic and the customer service is top notch - we also got a new thermostat at their suggestion and it is on a completely different level than our old one - I highly recommend Ace for heating and A/C. read more

I have been using Ace Air Conditioning and Heating for the last 21 years for the installation of HVAC systems in several properties. Their product and service is excellent and I can highly recommend them. Kevin Cain has done the estimates/proposals for as long as I can remember and I would not use anyone else. read more

I had a great experience working with Walter from ACE. I called the emergency number and he came out over a holiday weekend after hours with no issues. When he arrived, he was able to fix the issue with no problem. I would use ACE again with no hesitation. read more

Our heating went out over night. So we called Ace for emergency service. We figured it would cost us a bunch, but what can you do. We do have a contract with Ace (which I recommend). Jeff came out shortly after the call and replaced a fuse. He quickly diagnosed the problem and was very helpful ans friendly. Thank goodness for Ace and Jeff! Money well spent for a contract. read more

We reviewed a number of companies to replace our whole H/Air. Ace came in at a fair price and were extremely through in their estimate. Kevin Cain and his team were polite and knowledgeable of what we required. They may not be the largest company in the area but they are one of the best if not the best. I would highly recommend this company and its staff. read more

Beware, this is a brief recap of the 4-year long nightmare we experienced with ACE Air Conditioning & Heating Service, Inc. In December 2015 we made the grievous mistake of hiring ACE to replace our gas-fired steam boiler only to find out they had no idea how to work with our gas-fired steam boiler. First, they replaced our boiler with the wrong boiler for our existing system. They had to completely remove the one they originally installed, and with a bit of advice from another heating company, they installed yet another system. However, that system sputtered hot water from the radiators all over my home and specifically over my office desk. This system simply never worked properly over both of the winters of 2016 and 2017. After a series of sporadic and bumbling service visits, ACE decided that they would no longer service our heater, leaving us with a non-functioning heating system. After many, unheeded, attempts to speak with the owner of ACE, we were left with no recourse but to find and hire a professional heating company to fix the mess ACE made of our system. Finally, in January 2019 Foley Mechanical, the knowledgable heating company, re-piped our system providing us a nice, warm winter. The owner and management of ACE continued to ignore our pleas to pay for the repair work, hence affording us no alternative but to take them to small claims court in Arlington, VA. There is a slightly humorous side to the end of this story; instead of the owner of ACE personally appearing at the court hearing, he sent an attorney who tried valiantly to pay the amount of the claim just prior to our time before the judge to avoid a court-ordered and duly recorded mandated payment. We chose to allow the court to hear the tale and to record their decision in our favor. Knowing that heating/air conditioning systems generally represent a substantial investment, we offer this review to give insight into the disreputable business practices we suffered by unwittingly choosing to do business with ACE Air Conditioning & Heating. read more

Purchased a new house in November so we did not have to use the AC until May. When we did, we quickly realized the top floor was not getting cooled adequately. The temp on the main floor would be 70 degrees and the top floor was about 85 degrees. We have a one year old and she would wake up numerous times in a pool of sweat. Ace had installed and done maintenance on the AC about 2 years prior. When I explained the situation to them, they told me it would be routine maintenance and the next appointment they had was over 2 months out. After reading these reviews on the Company and how quickly they responded to others here, I tried to call back. At first no answer. After multiple attempts I got someone who told me she would have to take my information and have someone call me back. She explained they were caught off guard by the number of requests. I am surprised they did not anticipate the number of requests increasing when the weather turned hot. Its now 24 hours later and no call back. I will be using someone else. read more

I rarely rate companies, but this is a real exception to the rule....Ace Air Conditioning & Heating Service is without a doubt, the best out there. No high pressure sales pitch or fancy jargon as to what the problem is but their service guys are so nice, polite and honest that I cannot hesitate to recommend this company. They are punctual or at least let you know if there's a delay and work miracles to make everything right and without depleting our retirement fund!! read more

ACE performed a condominium association required furnace inspection and cleaning. Stewart the technician was far and away the best I have encountered over the past twenty years at least. Cleaning a furnace is not rocket science, but he did a thorough job and was pleasant to work with. In past encounters with ACE personnel, I have overseen the installation of a new HVAC system, as well as maintenace thereof. I have always found their technicians to be competent and sincere. I can recommend this company without hesitation. read more

If you love excellent customer service, great communication, trustworthiness and a smooth process, hire Ace! I purchased my condo about 7 months ago and go figure, the heat stopped working the week the temperatures were dropping! While on Yelp and Angie's List, I read excellent reviews on ACE. I knew I had to call and see if they could quickly come out to give me a quote. When I explained my situation, Jamie told me she could send Kevin out later on that morning! I was not only relieved, but thankful. Kevin came right on time and was so nice. I explained what was going on with the current system and how I didn't want to pour money into something that wasn't worth it. He was understanding and then looked at the system I had and took measurements and photos. He told me he would be able to email me with a few options that afternoon. As he left, he thanked me for the opportunity to do business with me (I was really impressed). I was so thankful that Kevin was not only nice but was never pushy. I could tell he wasn't about making a sale and never pressured me to select ACE. As promised, I had the quote that afternoon! His quotes were excellent and competitive and even better then another I obtained. Before accepting the quote, I called and asked Kevin some questions which he was happy to answer. Seeing I didn't have heat, he assured me they could install the new system on Friday (today) which was only 2 days after I signed and accepted the quote. Well, the crew they sent was amazing! Matt and Carlos called when they were on the way and even arrived early. They got right to work but made sure to cover my carpet and floor with drop cloths. Matt was working on the inside unit so I got to talk to him a bit. Both Matt and Carlos were courteous, respectful professional and worked efficiently. Before Matt left, he made sure to show me how the system and new thermostat worked, cleaned up and made sure to answer any questions I had. ACE, thank you for the great customer service and experience. I am so glad I found your company and thankful to have heat before the snow comes! read more

I highly recommend ACE Air Conditioning and Heating!! We recently had our furnace and air conditioner replaced by ACE, and they made this historically painful and expensive process very simple and smooth. Stewart was outstanding!! He knows his stuff and communicates in a very trustworthy way, he's the reason we went with ACE. One of the best service reps that we have ever dealt with in any business! That was followed by a very professional installation job. Matt, Luis and Wilmer did a fantastic job on the installation. They treated our home like it was there own and I would highly recommend them as an installation team! Thanks ACE. read more

Called Ace when discovered hot water heater was leaking. Told me to send photo of the space where it was in the basement and Stuart would get right back with me. He never did! I HAD TO FIND a FAST responding company to do the job!! Boo to Ace! read more

Great service when my furnace quit on one of the coldest nights this year. There was an electrical issue that could have turned into a very bad, dangerous situation (house fire=bad) and fixed it right away at a very low price without suggesting a very expensive "lets replace the whole thing" upsell. They gained my trust and I will call again in the future! Very nice to deal with and reasonably priced. I highly recommend them if you need service! Thank you ACE!! :-) read more

Clark C arrived with a mask and his courteous attitude. He performed a thorough check of the heating system. Ace has always had excellent customer relations and service techs. read more

Ok...I'll try this again. Have a furnace down. Adrian from Ace showed up on time, was presentable, polite, reassuring, knowledgeable, fastidious and efficient. He went to great lengths to diagnose the problem, identified it and did his job to a most excellent standard. Hopefully, the balance of this job will come to a successful conclusion. Ace AC and Adrian delivered. read more

One of our gas furnaces failed - ACE diagnosed the problem and offered to repair it for a reasonable price under our maintenance plan for our systems. Since the systems were 17 years old we asked about the cost of replacing the systems. They offered a very good package to replace both A/C & heating systems during this COVID-19 crisis. They replaced both systems in 7 hours - start to finish - and that includes complete cleanup - with everything up and running. We are very pleased with their install. They wore masks and gloves during the installation - and this is the first time we didn't "look in" to see what they were doing! We highly recommend them. read more

I called Ace this morning because my furnace kept shutting off. The company was able to send a technician out today - YAY! I was told I would get a call when the technician was on his way. As promised, I received a call to let me know he was about ten minutes away. The technician, Stewart, was courteous and efficient. He did a very thorough inspection, advised us of some things to look out for and addressed our current issue. Because our problem was pretty minor we were only charged the service call rate, which was super reasonable. Very happy with the company's responsiveness, communication, service and price. read more
