Had BL James install a pressure reducing valve on our water line after a home inspection showed the supply pressure over 100psi. The lower pressure solved problems we were having with a shower valve and our ice maker. Easy to schedule the work, final bill came in line with the initial quote despite the plumbers running into some unexpected challenges. Not cheap, but reasonable price and work well done - would use again.

I had them replace my HVAC system. They offered me a competitive price, were very communicative and had great service. Not to mention, all their staff are super friendly!

Once again, I had a wonderful experience with BL James and Son. Bilingual Technician, Mauricio, showed up at his appointed window time and in 20 minutes replaced my AC’s capacitor, thus returning my home air temperature to my desired coolness. He was prompt, courteous, knowledgeable and shared with me about the service he was performing. I will always return to BL James and Sons for my HVAC needs. Thanks again to your expert crew.

B.L. James & Sons exceeded my expectations from start to finish. The entire team was professional, courteous, and clearly knew exactly what they were doing. They showed up on time, worked efficiently, and completed my new heat pump installation in a single day without cutting corners.What really stood out was how well they communicated throughout the process. After the installation was complete, they took the time to walk me through the entire system, explained how everything worked, and made sure I was comfortable using the new thermostat before they left. They answered all of my questions patiently and made the transition to the new system incredibly easy.It's refreshing to work with a company that truly understands the assignment—deliver quality work, treat customers with respect, and stand behind their craftsmanship. If you're looking for a reliable HVAC company that values professionalism, speed, and customer service, I highly recommend B.L. James & Sons.

BL James was super easy to deal with, were very responsive, and were very fairly priced. I received 3 proposals for my heat pump replacement and there's was the strongest both in terms of cost and value. Also, they focus on Daikin products and my deep research on Daikin strongly supported it was the best bang for the buck, especially when considering their 12 year warranty.The install was scheduled within only a couple of days after i signed the contract and the install team was very efficient, respectful, and was not disruptive. Gustavo and Eduardo were a pleasure to deal with and explained everything. They also came in the 1-hour window they said they would, which i dont take for granted.Ill be using them for my other HVAC needs.

Luis and Israel worked to replace our old water tank with brand new tankless system today and they did excellent job!! Kudos B.L James!!

I got BL James&Sons from Checkbook because a toilet leaked into the condo below. They arrived on time, were familiar with the bldg and where to park. Re-seated the toilet and waited till building maintenance confirmed the leak was fixed. I am impressed.

I live in a condo building with PTAC wall-style airconditioning/heating. BL James provided excellent service in the installation of a new PTAC unit. It was installed 4 business days from acceptance of their quote. I'm very appreciative.

2026-07-12T19:07:13.884Z

Prompt, helpful. Repaired both a split vac and a home HVAC

2026-07-10T00:29:32.315Z

I called BL James & Son to diagnosis an HVAC unit that stopped working in the middle of a heat wave. The technician Mauricio came on time and he was great with my tenants. He was able to diagnose the issue and fixed it on the spot. He even took a look at the other HVAC units in the house to make sure they are working as intended. I appreciate the professionalism of this company, their skilled technicians, and top notch communication through out. This is my second time getting great service from this company, and I keep coming back to them with full trust.

2026-07-09T18:29:20.217Z

I called them Fri 6pm on July 3 with a broken whole house A/C and they had someone to my house within an hour who fixed it. Great service and reasonable cost for after hours on a holiday weekend.

2026-07-03T14:10:13.853Z

Thank you so much for scheduling me so quickly. Jose was great, and I really appreciate you having come out before it got so hot. Happy Fourth of July to all of you!

2026-06-30T20:31:36.070Z

BL James & Son recently replaced the split-system air conditioning in my older home. Their technicians were prompt, knowledgeable, courteous and left the job site immaculate.

2026-06-26T20:42:56.101Z

BL James and Son are PHENOMENAL!!! First of all, they are TRUSTWORTHY. Exceptional customer service. They can fix anything. They have been maintaining my Arlington house since 2003. Last week, I had an emergency AC weekend after hours issue that they fixed in an hour. This week, I had a gas leak. They came out for an emergency visit during a winter snowstorm to fix the job. They do the same with heating, AC, plumbing, electrical. There are benefits to being a longtime customer during a time when other contractors can be a real drag, these guys are the very best. On time, professional, smart, common sense, family business, ethical.

I had a leaking bathtub that was coming through the ceiling. I had tried to unclog it myself and in the process had somehow loosened the nut. George came on time and promptly fixed the nut and didn't charge us for it since it took him seconds. I remembered that the pressure release valve on the water heater was leaking water occasionally. I showed it to George and was informed that it was a potentially catastrophic problem. I had to go to work so I showed George where the water cut off was in the basement and went to work. When I returned, my wife told me that he had fixed the problem and given us a very fair bill. I'll be using BL James for my HVAC and plumbing needs from now on. Other companies would have probably charged me for the bathroom leak. I was also informed by Aaron that he had a person that could repair the drywall damage on the ceiling.My outside AC unit was screaming this morning so I turned it off and called BL James again. Chris had a guy coming between 3 and 5. Mauricio was here at 3 and diagnosed the problem. The motor was completely shot. He gave me a quote, got the part, cleaned the unit and competed the repair by 5:30! Their service is the best in NOVA. I'm attaching pics of before and after shots of the coil and Mauricio showing off his work.

Both my daughter and I have hadBL James come out for a number of repairs and every time their work has been exceptional.I have often been surprised that they are able to find a way to fix the problem that is less costly than I anticipated.For example, another Company estimated a project at over $800 and they were able to do the same project for under $300.I have found this company to be honest, always on time and with good communication. I wouldn’t want to hire any other company in the future.

2026-06-20T14:32:06.871Z

Excellent service. Successfully repaired water heater. Knowledge, articulate, professional technicians. Highest recommendation!

2026-06-19T18:51:15.092Z

Mauricio did a fine job of diagnosing the problem and taking care of it. We will be following his recommendations. Thanks, You

2026-06-15T13:16:47.858Z

The semi-annual HVAC service provided by the Mark, the Tech on June 5, 2026, was excellent. He kept me informed of what he was doing while he was checking my two (2) units and changing the filters. He was honest and trustworthy. I recommend B.L James & Son without hesitation or reservation.In addition, on June 12, 2026, Mauricio, the Tech came to replace the capacitor on my unit. He did an excellent job. He kept me informed along the way. I also recommend him and BL James without hesitation. for this type of work.

2026-06-11T14:26:17.085Z

Just WOW. I just recently became a home owner in Arlington and I needed to find a good HVAC company to service my system twice a year. I found BL James & Son through a personal connection and I can assure you they have almost 5 stars on here for a reason - they simply are the BEST! They told me they would be here between 8:30am - 9:30am..and Jose arrived promptly at 8:31am. Jose was extremely professional and kind. Jose walked me through what he was doing and treated me as if I was his family. I feel like I have a trusted advisor and partnership with this company and I feel like I am in great hands. You can’t buy peace of mind. So thankful to you Jose!! I would 10/10 recommend BL James & Son to any and everyone in the area.

2026-06-09T20:46:43.903Z

Prompt, professional, and trustworthy. Mauricio got us up and running quickly and I feel confident we are going to stay cool this summer.

2026-06-08T18:36:35.214Z

We needed a new A/C system on short notice, and B.L. James & Son took care of us at a reasonable price.

2026-06-06T20:01:40.411Z

Service was courageous and professional.

2026-06-03T00:00:27.387Z

I had a major failure of my hot water heater and BL James & Son did a great job taking care of everything. They responded right away, because they have an actual person answering the phone, which is somewhat rare these days. Their supervisor did a site visit the next business day and I got a quote within hours. The work was scheduled for the next business day after I approved the quote and the crew did a great job.

2026-05-29T20:56:41.020Z

2026-05-29T20:34:51.620Z

Quick, polite, and explained everything clearly. Very professional.

2026-05-28T03:20:41.002Z

B.L. James & Son technician Israel arrived at 8:41am for his 8:30-9:30 window. He performed three services for me today. He installed a new drain line in my first floor bathroom, replaced a cartridge in my kitchen secondary sink, and replaced a bathroom toilet valve and toilet hardware in my basement bathroom. He was communicative, timely, and bilingual throughout the process. I couldn’t be more pleased with the service he provided.

2026-05-23T17:10:02.044Z

Mark from B.L.James was fantastic. Solved our HVAC problem within minutes, then spent much time and energy making sure it was operating as it should. I couldn’t recommend this company more highly!

2026-05-17T14:56:16.305Z

Really professional and helpful service - very pleased we chose B.L. James over a few others. Great experience this past week when they replaced our aging HVAC system with a new Heat Pump/Furnace hybrid combo. Aaron made two visits to go over options and setup, and the four-man crew was exceptionally strong. Explained what they were doing, answered questions, clearly trained and knowledgeable, and left the site spotless. They day before we also had B.L. James fix a toilet leak and Luis was just as helpful and professional as the HVAC crew. Again, an excellent experience across the board and would definitely recommend to others.

2026-05-14T16:26:48.034Z

Very thorough, reasonably priced, and attentive to taking care of my home. Technician even cleaned my intake vent so my electric bill would stay lower. Used them for HVAC services and plan to use BL James & Son for plumbing as well. So glad I found this company after my other firm closed.
