I found ABC 24 Hours online, and I couldn’t be more pleased with the service I received from the technician, Mike. He came over on a Saturday as I was having issues with the air conditioner and diagnosed the problem right away, and informing me as he went along of what was going on. He was so knowledgeable, and happy to explain things to me, so that I actually learned a few things about my heating and cooling systems. He was extremely polite, friendly, and professional, exactly as I would hope a technician would be. He also told me about making sure to do maintenance checks regularly so that I wouldn’t have to pay more to replace broken parts or the whole unit. My air conditioner has been working perfectly since he came, and I would highly recommend ABC 24 Hours to all my friends and contacts! Customer service is what makes the biggest difference in any industry and why I will trust ABC with all my heating and cooling concerns from now on.

I’ve used ABC 24 Hours twice now, and both times were great.  I trust them to give honest assessments, which they do for free, including a cost estimate!  They don’t fix things that aren’t broken, so I know they are legitimate.  One of the times I needed my furnace repaired because it was making a funny noise, and they were able to diagnose the problem right away and suggested two ways I could get it fixed.  The second time I used them, it was to actually switch furnaces because I was planning on selling my house, and they had told me the first time that I should or could get a new furnace very soon, or else I might keep having to get different parts repaired, as it was ageing.  I figured the house would sell better with a new one, and they were so great at detailing all the options or types of furnaces I could get.  I didn’t feel rushed or pushed to buy a certain kind or brand, and I really appreciated that.  I felt taken care of both times, and that’s obviously their company standard!

Mike is the best!  Having a broken AC in this humidity makes anyone cranky, but Mike was so prompt, easy going, and friendly that we forgot about being cranky and were just excited to get the issue fixed.  Luckily he was able to figure out the problem right away and fix it on the spot that very day!  Whenever we do need a new unit or any new parts I plan to call ABC 24 hours!  I’m sitting in my nice and cool, air conditioned living room as I write this! Aah…

I recently used a coupon that I saw on ABC 24 Hours’ website for $65 off an all-season’s system check-up for my office’s HVAC unit.  I was nervous about what they would find or if they would tell me I had to change everything, but I wanted to be sure that it was all working properly since a hot summer was coming.  Turns out they just needed to update one part on the air conditioning unit, which was pretty inexpensive.  They showed me the part and described exactly why it needed to be replaced.  They seem to really go the extra mile when it comes to customer service, and made me feel at ease.  I was able to ask questions, and I plan to schedule a routine maintenance check up every season with ABC 24 Hours!  I’m glad to not worry about finding a reliable company every time I need something!

I own a dental practice in northern VA, and last year I bought a new building that we completely re-furbished.  We used ABC 24 Hours for our HVAC needs, and we had them install a rooftop commercial air conditioning unit.  I would highly recommend them to any business or company that is in the process of modernizing, fixing their HVACS units, or considering switching to a rooftop unit.  ABC 24 Hours came out to our property the next day that we called, and explained to us very clearly exactly what we would need and since then everything has been working very well and we’ve had no complaints!

I can finally sleep again!! I was having dry air issues and feeling like I had a super scratchy nose when I would wake up every morning.  A friend told me they had gotten a humidifier installed and it helped them so much! I bought a little one from a store, but it didn’t last very long or seem to work properly.  I looked on Google for more information or for someone who could install one permanently for me.  I came across ABC 24 Hours and found that they do humidifiers.  I wasn’t sure if they did small time ones for a single person like me, but they were very friendly over the phone and said they would send someone out right away to see my space and give me a price quote.  They actually brought a humidifier with them, based on what I said over the phone about the size of my place, and after giving me the price quote, I just told them to go ahead and install at the same time.  I was so impressed because I’ve had other repairs done and things installed, and I’ve always had to schedule so many appointments and wait so long for the job to be done.  With ABC 24 Hours, it was all done so quickly.  Hopefully it never breaks, but I know they will fix it for me promptly if it does!

They really are 24 hours!  I woke up in the middle of the night to hear a weird clanking noise coming from within the house.  It looked like my air conditioner, and when I turned it off the noise still continued, and it was blowing air out of only 2 rooms and not the other vents.  I found their number online, and I was surprised when someone actually answered the phone!  I said I didn’t think I would be able to sleep because it was not turning off and the noise was very loud.  Mike, the technician, actually came out to my house in only an hour!!  I was shocked, as I thought it would be a huge hassle to get this fixed quickly.  He managed to turn it off and stop the noise, and he said he would come again the very next day and bring the part that needed changing.  Mike even offered to me that I should use a coupon on their site, for $25 off repairs, which I wouldn’t have known on my own and would have paid the full price! Awesome company-definitely recommend.

Caring. Skilled. Trustworthy- my three words to describe ABC 24 Hours.

Going over the books for my small business, I was looking for ways to save money, and I thought that something necessary but simple was costing a lot-HVAC.  I decided it didn’t hurt to get an opinion on if there was a way to save, or change things so that it wasn’t costing me as much.  I saw that ABC 24 Hours gave free cost estimates, so I called them and a technician was dispatched to my store the very next business day.  Mike immediately said he could recommend me some different units that I could get installed, and he sat down with me to go over the numbers on how much I would end up saving in a year if I used the new systems instead of the old, noisy, clunky one I’d been using for far too long! I got all of that from a free cost estimate, which I don’t think most places would provide.  Now, I love my new units because they are so modern, don’t make much noise, and of course work way better, and it’s like an added bonus that I’m also saving money at the same time!
