HVAC reviews in Fairfax, Virginia

I was impressed with the communication from the company concerning my appointment time. My technician was polite and answered all my questions. I appreciated his honesty about the cost of repair vs buying a new washing machine and we had a good discussion about brands. I would highly recommend to others.

As a contractor who has relied on Argent Heating and Cooling for countless projects over the past decade, I regret to share my recent disappointing experience with their services. The company, now under new ownership (Rachel and Robin), has failed to uphold the standards of customer care and service reliability that was once its hallmark.
Recently, I encountered an issue with a system they installed just three months prior. Expecting the responsive service and support I had become accustomed to, I was dismayed when my request for service was outright refused. This lack of accountability and support is unacceptable, especially considering the short time frame since installation.
The refusal to service recent work not only undermines my trust in Argent Heating and Cooling but also leaves me questioning the quality of their installations as a whole. As a result, I am compelled to seek other providers for future projects and can no longer recommend Argent to my peers in the construction industry.
I hope this feedback serves as a constructive critique, prompting Argent Heating and Cooling to revisit their customer service policies and honor their commitments. Until then, I will be taking my business elsewhere.

NOTE: In the past week, we have observed a series of unwarranted one-star reviews on our Google profile. These reviews were posted by Rachel and Robin, the new proprietors of Argent Heating and Cooling, as well as two of their employees. We want to make it clear that these reviews do not reflect the true nature of our services or the satisfaction of our genuine clientele.

The individuals from Argent were never clients of Steadfast; rather, we utilized their services. We believe these negative reviews are a direct response to our critique of Argent for failing to honor their warranty. This appears to be a deliberate attempt to tarnish our well-deserved reputation on Google. Consequently, we have terminated our business relationship with Argent due to the unprofessionalism exhibited by the new management.

Moreover, conversations with a former long-standing employee of Argent have revealed that the work environment under Rachel and Robin’s leadership became untenable and toxic, leading to his resignation.

We are currently in discussions with Google to address these false reviews and are exploring all avenues to protect our standing. Our commitment to providing exceptional service and craftsmanship remains unwavering, and we are taking proactive steps to ensure our reputation is accurately represented.

Very incompetent, unprofessional, and unreliable service. Showed up late the first day, wouldn't work unless we said, verbally, they weren't liable if they break anything, many calls unanswered, didn't show up the next day they said they would come, man used our restroom and left the toliet seat up, left a huge mess, and guess our appliance was not fixable so its still broken. Will not use them again. Two stars because they did come the morning I called.

Tamika - the Argent technician was very thorough, took many pictures of our system, and explained in detail what were the problems.

After working with a few HVAC service providers in NoVA, I settled on Argent (and became a member) as they have fantastic service and are always available within 48 hours.

I had a fantastic experience with my hvac maintenance and my plumbing inspection. Thank you Argent.

Cameron Colt was very nice and fast to solve my problems. Highly recommend!!

They use to be good, but now use lower paid trainees. Trainees need to FaceTime headquarters to try to diagnose a problem and fumble through it. In my situation they got it wrong several times and a misdiagnosis cost me $1200+ dollars and 3 repeat visits all charged at full price. I had an “annual contract” with them, so you might expect that e got the best available service they have now. When questioned about the fact that heater would not turn off and the temperature in the house was 85+ degrees and we had to open the windows in winter to cool down the house, tech said “that was normal.” After many visits at full price and a second diagnosis that cost $500+, we’ll see if it is even fixed. If not, I will go somewhere else. I would highly recommend that you find someone else.

BUYER BEWARE!! Technically incompetent, shady business, and unresponsive customer service.

Argent installed my new heating/cooling unit. Days after moving into my new build (with the new heating/cooling unit), insulation from my heat melted all throughout my heating/cooling closet releasing terrible fumes and nearly causing a fire.

Fast forward a year and a half later -- my auxiliary heat (from my 1.5 year old HVAC unit) burnt out. Keep in mind, most HVAC systems have 10 - 20 year warranties. Argent sent someone out, said it needed to be replaced, and then I had to follow-up via phone 2 weeks later to get a status update. Darnella informed me the part was ordered and would be here in 4 weeks. During this time it was sub-30 degrees more than half of the time, with no heat.

4 weeks later, I called and was told the part had not been ordered. It would take another 4 weeks. Then Robyn took my call and said it had been ordered, but it would still take another 4 weeks *headscratch*.. really?

Robyn informed me she would try to get the manufacturer and the distributer to cover the costs.

4 weeks later, I had to call again (because Argent doesn't know how to update their customers apparently), and was told it would be another two weeks at least. Robyn informed me the manufacturer, distributer, nor Argent would cover the parts or labor for the piece.

All to say, I've wasted my time dealing with this incompetent company. There hasn't been one bright spot: their units, the installation, and the people are all faulty, incompetent, and rude at best.

Don't waste your time! Seek HVAC services elsewhere!

If I could give zero stars, I would.

The customer service has been appalling. I spoke with Christina at the call center, who said she was putting me on hold—but then hung up. When I called back, she sent me straight to voicemail multiple times. Out of curiosity, I called from my wife's phone—she picked up immediately, but once she realized it was me again, she hung up.

No managers are ever available, and despite being told I’d get a call back, it’s now been four days and I’ve heard nothing from Manager Philip. It’s clear from other recent reviews that this company is more interested in collecting payments than in actually resolving issues.

There are plenty of reputable home service providers in the area—avoid this one and take your business elsewhere.

We have been long term customers of Argent Heating and Cooling. Today, we had no heat on a somewhat chilly spring day. We were able to get techs Melo and Santiago here within a couple of hours. They diagnosed the problem, repaired and replaced the bad valve, and suggested remedies to prevent further issues. We recommend this duo, as well as our normal tech, William. Shout out to Jessica for her prompt response this morning!

They replaced our system, went over all our options and gave us a solution that fit our budget. Work was completed quickly and cleanly, the installers were courteous and professional. Would highly recommend them!

The two technicians from Argent Heating and Cooling were professional, efficient, and thorough. I was very impressed with them. I wish all service people were this good.

I had Argent to my home in Summer of 2024 to do a leak check on my AC unit. They performed the check and did not find any leaks. They refilled my AC unit with refrigerant and let me know there was no leaks. Spring of 2025, my AC was not working again. A leak was found in the line leading to my outdoor HVAC unit. I then contacted Argent in Spring of 2025 to request an estimate on replacing the line with the leak. They wanted to charge me again for another service call and leak inspection. Overall service did not fix my issue and wanted to double charge me for work they did not fix the first time. They were responsive and polite, but I would not use Argent again. Their work was insufficient.

Contacted Rachel and her team to see if they could help a client with a leaking hot water heater, being an HVAC company I had no idea if this was something they did, to my surprise it was absolutely something they could help with! They sent a technician out the next day to help identify the issue and noted a new tank would be required. They identified the best product for replacement and ordered it same day and came back a few days later to install. Not only were they responsive but their whole team was professional and knowledgeable from start to finish. I highly recommend them.

I called Argent when needing help with my AC (the VA weather has been an emotional roller coaster)! I spoke with one of the wonderful ladies in the office and then received a call from their sales guy, Ron, to come on out and look at my system. Ron was amazing and gave me a quote I could not resist (cheaper than other companies with better efficiency.). Ron then scheduled his guys to come on out and Keith and his team did great. My AC has had no issues and any questions I have are answered in a timely manner. The service techs are knowledgeable and are some of the kindest young people I’ve ever come in contact with.

I would highly recommend Argent for all your AC/Heating needs. The team will take care of you from start to finish! Whatever you may not understand regarding your system can be answered by the team!

Ron, Keith, Techs, and Wonderful office staff you guys weee incredible! Thank you.

A technician was sent to my house to take a look at my spa and they charged me no minimum fee to come out and assess the work. And gave me a reasonable estimate.

Do not use. Shoddy service. Neglect warrantied items. Poor advice. Just everything is bad. This company should be put out of business since its sale to corporate years ago. You will be sorry using this company.

Outstanding support and professionalism. Mike was my service tech and is such a knowledgeable and engaging teammate to represent Argent!

Robert’s Heating and Air in Arlington was able to diagnose and fix the problem. Added refrigerant to heat pump. Felt kind of pricey, though.

I recently had an awesome experience with Argent Heating and Cooling for my HVAC needs. Their customer service was super friendly and quick to help. When technician Alex showed up, I was really impressed! He was professional, knowledgeable, and took the time to explain everything in a way that made sense.

Alex didn’t just fix the issue; he also gave me great tips on keeping my system running smoothly. I couldn’t be happier with the service, and I highly recommend Argent Heating and Cooling—especially if you get Alex as your technician!. But I have had others and they have been great too!
