Fast service. Very knowledgeable. Did work on a Sunday morning which wasn't expected but was great because our A/C compressor quit working in the middle of summer. read more

Bob did an amazing job troubleshooting my HVAC at a reasonable price with great customer service! HVAC was acting up. Ultimately, it needed a full replacement. It was not under warranty. Quotes were obtained via Yelp from several local HVAC vendors. Original in-person diagnostics was obtained from a large HVAC company, also. They were priced too high and lots of upselling. Bob had a great price and diagnostic service was prompt, which was far superior than the rest. He was swift in ordering the new HVAC unit. He even assisted with the home owners insurance process, as he's a subject matter expert. He personally installed the HVAC with one of his other assistants. It's running smoothly, as we checked heat and cooling. He gave pointers, as well. I highly recommend Bob. Support this small business. Best prices and superb service in the Arlington area. No price gouging here. Just honesty and reliability, at an awesome price. read more

NOT TO CODE! had him install a new hot water tank, furnace, and AC in 2022. Only the AC was installed to code according to the company I called in 2024 to fix the broken hot water tank. It will be cheaper to replace the entire brand new hot water tank than to bring the existing one up to code. read more

Was having an issue with our thermostat and called Bob. He was great and gave us a few tips before coming over. They resolved the issue and saved us $250 feet from other companies for just showing up. Highly recommend him! read more

DO NOT HIRE BOB. I was unlucky enough have him replace both my furnace and my heat pump. Neither work and he refuses to come back out to fix them. He ignores all my calls and texts. I am now out $10K because of this scammer. read more

I had the pleasure of having Bob from Allied Fast Services come to my house and installed a new 16-seer unit. And I must say, the experience was truly outstanding. In less than three hours, Bob efficiently completed the installation, demonstrating his exceptional skill and expertise. Not only did he ensure that everything was set up perfectly, but he also took the initiative to pull a permit, demonstrating his commitment to adhering to regulations and ensuring a job well done.He went out of his way to buy materials needed for my old house. Bob's professionalism and attention to detail were truly commendable. Throughout the entire process, he exhibited a thoroughness that instilled confidence in his work. From carefully inspecting the area before beginning the installation to meticulously checking every component and connection. He made several recommendation to change multiple items since my unit was 20 years old. Good luck getting an HVAC company in DC willing to pull a permit. Once you bring that word out, you will be having a rundown. Bob was the only HVAC Master in DC who didn't blink an eye when I requested a permit. Please do yourself a favor and call him, it will be the most pleasant experience you will ever have. read more

Bob is an incompetent crook who stole a part of my HVAC. When my air conditioning broke the night before July 4, I sent several requests on Yelp. Bob responded promptly and showed up the following morning. At the time, my system had started working again, but I thought someone should look at it. After viewing the condenser, Bob assured me that the issue was I needed a new "capacitor," which would be $200. I said ok, and he installed it. After he did, the air conditioning stopped working all together. When I asked him about error messages on my thermostat, he said he doesn't know anything about Carrier units (the top selling HVAC in the country!). After admitting he didn't fix it, Bob told me that he wouldn't charge me and that "at least I got a free capacitor." The next day a professional from a legitimate company came over. When I mentioned the new capacitor, he told me that the one Bob installed was used, broken, and rusted out. The issue was the motor, but now I needed to pay for a new motor AND a new capacitor. To add insult to injury, Bob got black soot all over my windowsill and door. DO NOT USE THIS GUY. Also note that some of his over-the-top five-star reviews are from people outside of the DC area, which is very suspicious. read more

Bob never showed up for our agreed appointment and never contacted me to explain his absence or to reschedule. Bob's voicemail prompt talks about the importance of your (missed) call, but it seems his customers are not important to him at all. Talk is cheap. Action is the best and most reliable measure of a company's principles and values. If a vendor can't manage to show up when promised, how can they be trusted to do the work? DO NOT TRUST ALLIED SERVICES. THERE ARE MANY OTHER HVAV COMPANIES, AND I STRONGLY ENCOURAGE YOU TO CALL SOMEONE ELSE... ANYONE ELSE. read more

Outstanding experience working with a company for installation of new A/C. It's not easy managing a home repair project from out of state, but Robert eased my concerns with back and forth dialog answering questions before beginning and providing updates with the project until complete. Job well done at fair price and delivered as promised. Could not ask for more. read more

Our furnace broke the day we left for vacation and Allied showed up the same day for an inspection and replacement. Bob was honest, prompt, and efficient. Our furnace has been pumping sweet heat ever since. read more

Bob was great to work with. My heat pump went shortly after I bought my condo and being a new homeowner, he was very helpful in explaining to me what my options were and how to best care for my new heat pump. In addition he made some tweaks to my thermostat the have helped my heating work perfectly ever since. He was able to have my new heat pump installed on the roof in under 24 hours from when it broke. Awesome service! read more

I highly recommend Bob at Allied Service Company for HVAC and plumbing needs. Between April 2020 and January 2023, Bob has replaced our AC Compressor, Air Handler, Dishwasher and Garbage Disposal.

Our gas furnace stopped working the day after xmas and the coldest day of the year. Bob came the next day, replaced the furnace in only a few hours, gave us a great price, and we were warm and toasty the same day! I would highly recommend Bob. read more

Bob is terrific. He's responsive, efficient and gets the job done quickly at a very fair price. He showed up for the appointment at my townhouse in Capitol Hill 10 minutes early and he replaced my furnace and AC unit for literally half of what Michael & Son's wanted to charge me. He also connected a Nest so I could control the temperature from my phone. Everything is working great. I am an attorney and always do my due diligence before hiring a contractor. I received multiple quotes, talked with multiple contractors and Bob was the best. Save yourself some time googling various companies and just hire Bob. He's absolutely no-nonsense. read more

In an attempt to be as unbiased as, possible, I will describe the events and then my take on them afterward so that you can make your own mind up. My ac unit stopped blowing air and as such called Bob to come and review the system. Bob came out and upon reviewing the unit told me there was a leak and that it would need to be refilled with freon and maybe even replaced. Bob also noted that there was a problem with the compressor. After returning the next day with freon, it cost a total of $600 dollars to refill. I noticed that the cool air was still not blowing out of the vents and asked Bob who said it might take up to 24 hours to work so after 24 hours I called Bob back who said that it must be the compressor and therefore the entire heat pump must be replaced because compressors are not easy to get and install and therefore the cost would be comparable to replacing the unit which he could do for $3,700-$4,000. Bob did mention that the cost of the freon could be taken off the cost of the new unit. This is where the problem starts. To ensure that the problem could not be fixed otherwise and to double check my warranty I called the manufacturer and had 2 other AC maintenance companies come by. Both immediately identified that it was in fact not low freon but instead due to the electricity not reaching the circuit board. After the circuit board was replaced, I asked for the compressor to also be checked (which according to both companies was considered fine), and I also mentioned the freon leak. To check they looked at the amount of pressure and found that the freon was WAY overcharged which can cause significant damage to the system. As such, this was making the system as a whole shut down the moment the AC started to protect the unit as it was way above the safety threshold. To fix the problem, the freon had to be redone. For clarity, my unit can hold a maximum amount of freon of 5.5 lbs according to the manufacturers and as listed directly on the unit. When the existing freon in the system was removed to be refilled a total of 15 lbs was taken out! I brought this to Bob's attention and asked him what he would like to do about it and if he wanted to make things right. At first, he denied overcharging the freon saying that the unit was definitely more than 5 lbs stating, and I quote "I did not overcharge your system I carry a maximum of 10 lb with me, and unless you have the smallest air conditioner in DC it runs on more than 5.3 lb." Then when I mentioned that the unit clearly said it was 5.5 lbs, he then changed tact and said that the manufacturers set up the unit with that much to begin with (which directly contradicts what the manufacturers have told me now). As a result, Bob has denied all responsibility and has stated that if I can get him the 15 lbs of freon (which in my opinion seems to be an admission that he overcharged it) he will refund my $600. He did not offer to remove it himself or do anything else to rectify the situation which I may remind you potentially caused serious damage to my unit given just how overcharged it was. My thoughts: I understand that the problem may be misidentified, and although I do find it odd that Bob was so quick to say it needed new freon, in an effort to be good faith I will chalk that up to a misdiagnosis. However, what is clearly negligence is not following the on-unit limits and overcharging. Furthermore when this was brought to his attention that the initial solution he went with did not solve the problem all that was suggested was replacing the entire heat pump unit because "compressors are not parts you can get easily and will cost almost as much as replacing the unit." Finally to not offer any assistance to remedy a mistake on his part (or even an apology for the potential damage caused by overcharging the unit), and instead try to deny any responsibility is just bad business practice. In my opinion, this entire situation can be understood in 1 of 2 ways: At best, this series of events is potentially one of negligence, lack of effort, and poor customer relations. At worse, this series of events is potentially one of shadiness, deliberate manufacturing of issues, and upselling. Neither of these conclusions represents a business I want to trust with my home appliances in the future. read more

If I could, I would give Bob and Allied a bonus star! I live some distance away from DC and support an aging parent from a distance. Imagine my panic and dread when I learned that the AC in our DC family home stopped working, during a heatwave no less. I contacted a few companies and Allied responded quickly (on a weekend) and had turned around a repair in less than a day. Bob was prompt, offered a fair price, and a clear explanation on the nature of our repair/replacement. Most importantly, Bob was patient as my family and I worked through details regarding onsite visit and payment. What could have been a stressful situation was handled efficiently, empathetically, and with the utmost professionalism. read more

My heat went out at the house and with a short request on Yelp I had a reply back from Allied in minutes. I was offered a reasonable rate and had a technician at my house within a couple hours. The technician, Bob (Robert), even actually arrived at the time proposed which is uncommon for just about any other service I've requested in DC. Luckily it turned out to be a simple problem that Bob was able to resolve, offer up some additional tips, and close on a more than competitive rate. If you live in the area, have a friend or relative, be sure to check out Allied for a reliable, trustworthy service and support a local business along the way! I'll be keeping Bob's contact readily available. read more

Quick honest resolution... Very reasonable... Showed up on time with free diagnostic...Will call again!

We've used Bob and Allied Service to replace our AC, furnace, and water heater. They always do great work and thoroughly explain issues and option. Most recently, we were having issues with our furnace and Bob came by and figured it out very quickly and had us back up and running. They have me as a customer for life, can't recommend them enough. read more

So happy I found Bob through Yelp! Our A/C decided to crap out, during the HOTTEST week of the year, and we immediately panicked. Called several places but they weren't available quickly enough (and one just flat out didn't show). Once I got in touch with Bob, he was able to come out immediately and diagnose the issue. Not only that, but he had the new part we needed (a fan motor) in his shop - and he came back just an hour later to install it! Now our A/C is working perfectly for a very reasonable price. Bob was quick, efficient, and knowledgeable. I also asked him about getting a new water heater, and he assessed and discussed our options for replacement, which was great. He will definitely be our guy for this stuff going forward! read more

Quick and efficient, no BS. Showed up when he promised, told me the truth, and will be called again when I have HVAC needs.

Bob and his team are gems. He was responsive, flexible, and made every effort to meet our needs throughout the entire process. He handled our insurance company so we didn't have to, completed installation of a brand new AC system on time, and was a delight to work with. We've had some miserable run ins with contractors in the area but our interactions with Bob were the cure to what ails us! Hire him immediately for any heating or cooling need. read more
