Alex and his team are the best! Alex came to my house to do an assessment on our broken HVAC. He sold me a water heat tank and Carrier system that is more than $2000 less than the quote Home Depot and Costco offered. His Techs came in on the day of installation on time, with tarps and did an awesome job! Everyones responsive and answered all of my question. I will definitely recommend L&B Universal to my friends and family. read more

Because of its lack of honesty and accountability, I do not recommend L&B. I paid L&B to install a Bradford White hot water heater and Amtrol ST-5 expansion tank in 2021. I noticed a leak from the ST-5 a few weeks ago. Judging from the water stain on the floor, it had been leaking for a while. Contacted L&B & explained what happened, identified the tank model (ST-5), plus photos of the items. Mike from L&B stated that it only had a 1-yr warranty. I mentioned to him that on the receipt, it says parts are warranted 6 years and that on Amtrol's website, it states that the tank has a 7-year warranty. To which, he simply replied that they don't cover the expansion tank. So, I contacted Amtrol for warranty coverage and was politely told to go through L&B and that they'll put this in as a warranty claim. I relayed that to Mike who said ,"No. We have to get it and the return the old one for warranty." He also said that it'll cost $300 to replace it. That's absurd. All reputable companies would only try to verify you as a valid customer with a receipt, get your current contact information, plus photos of the items, to honor the warranty. For example, I bought an Esprit ET-488 treadmill back in 2010. Its 2.5-hp motor went bad in 2022. I contacted Esprit about it. Without hesitation, the it sent me an updated 3-hp motor that's worth around $300. Other than that, I'd also had great experience with the Moen company in obtaining free replacement cartridges for my faucets on several occasions in the past. Bottom line: We as paying customers all want reliable parts and services. Do some thorough research and find a company that you can count on for descent service and for peace of mind that the parts will last for a while or be covered by warranty, especially when it comes to major household items, such as the furnace, AC, or hot water heater and accessories. read more

L&B responded Very quickly. They were very knowledgeable, and the price and workmanship were great!

we have contracted with L&B for over 15 years and remain thankful for their responsive customer service, technical competence, and fair market pricing. read more

Mid February, 2025, in the coldest weather, our heat pump was dead after 17 years. After 4-5 estimates, we chose L&B Universal not only because their price was several thousand dollars lower than others, but also because Mr. Lee, President of L&B Universal, carefully examined the heating ducts and vents and suggested to redo them with unbelievably low costs. Also, he explained the pros and cons of several different systems in detail for us to choose the right one. Mr Lee had the system installed next day for us to have heating as soon as possible because the weather would continue to be cold for a while. The new heating system works great! L&B Universal's cost was not only the lowest, but their services couldn't be better. A few days after the installation, Mr Lee called us to make sure it works fine. He is genuinely interested in helping his customers. No Heating and Air Conditioning company could be better than L&B Universal!!! read more

Excellent job! Reasonable price, on-time arrival, and job done with high standard/expertise!

We had our ac and furnace replaced. Removal and installation was quick and very professionally done as promised.

Stay far away from this company! We had them install an HVAC unit in our house in 2017, and have nothing but problems since day 1. When they installed the HVAC, they also installed an Ecobee thermostat as well (which later failed, and they then told me the Ecobee was not compatible with the Trane...utter BS!). Every Spring and Fall when the weather changes, we have to have the unit serviced because it will not switch over from heating to cooling, and vice versa. The company that we are using now noticed that L&B Universal had re-wired the unit, and removed the low pressure switch, so the unit will just keep running, and never shut off if there is a problem. This company should be ashamed for this type of work. I advise anyone to stay away from this dishonest company, and I completely regret ever dealing with them. read more

They were very professional from start to finished. L&B Universal do truly cared about their client's! Thanks, Young Song read more

L&B Universal installed a new HVAC system at my home (Dec 2022) and a new water heater (Jan 2023). Mike and the staff at L&B were very helpful/courteous and followed up right away on scheduling all of the planned work. My technicians Johnnie and Sam did an outstanding job on the installation of all of the new equipment. They arrived on time for our appointments and they were very strategic, organized and worked diligently in completing the work. Johnnie and Sam answered any questions that we had and were very professional and polite to work with and explained both projects along the way. They also provided instructions and information about the new equipment after the installation was complete. Great care was taken and the work areas were left absolutely spotless. Outstanding communication, service and workmanship by L&B Universal. Thank you very much! read more

From Customer-Centric Company to Profit-Gouging Customer Nightmare in Three Years I bought a new Carrier HVAC system from L&B Universal in in 2014, under a 10-year parts warranty. All went well for the first three years and I received good customer service. Then something changed dramatically for the worse. In January 2018, after the usual periodic maintenance services had been performed by L&B Universal in the fall of 2017, and while I was on vacation, the unit blew its fuses, causing it to shut down and the water lines throughout my house to freeze and burst. This led to total Inundation of the living level and lower level of my home, making it uninhabitable for 2 weeks and resulting in over $25,000 of property damage. While L&B Universal never admitted this, according to the general contractor hired to restore my home, the blown heating system fuses were most likely caused by a failed blower motor or other maintenance issue leading to overheating. In the fall of 2020, only two years after the home had finally been repaired and the Carrier unit had again been serviced by L&B Universal and was still under the parts warranty, but after the labor warranty had expired, I paid about $150 for replacing a capacitor. Then, on 11/22/2021, during scheduled maintenance service, for which I was charged $90.00, the technician determined that the fan motor on the outside unit needed to be replaced and I was charged the outrageous amount of $500.00 for the replacement, which took 15-30 minutes to install. I had the technician call his supervisor to tell him that I was paying the $500.00 only under duress because I could not afford another flooded house as in January 2018. While in my home, the technician also, for unknown reasons, moved my washer, which contained a full load of wet laundry, and my dryer, out about 1 foot from the wall against which they had been installed. This caused the washer spin cycle to stop working. I reported this to the L&B sales manager, who claimed that the technician denied having moved the washer or dryer. I invited him to come out to verify what I had reported, but he failed to respond to the invitation. The sales manager also refused to refer my complaint about the outrageous labor charge of $500.00 for 15-30 minutes of work to the L&B project manager/general manger or president/VP, but instead offered me first a $50.00, then a $100.00 rebate, both of which I turned down. The going rate for HVAC work in my area is $75.00 -$150.00 per hour. My advice: Hire L&B Universal only if you want to have questionable and/or useless "maintenance" work done, to be ripped off for the "privilege," and then wish to risk a catastrophic system failure on top of it all. I was lucky that I had home owner's insurance when I had my HVAC nightmare in 2018. read more

I struggle before leaving a one star review on any organizations page. I have given this a lot of thought and I do feel that this review is justified and fair. You have a lot of choices out there when deciding on an AC repair vendor. I urge you to look elsewhere before hiring this business. The communication and excuses made by the "project manager" were terrible. After multiple failed attempts to fix my issue, I ended up having to hire a different company to fix my AC. I spent over a month going back and forth with L&B listening to multiple excuses. I would have had so much respect for them if they would have just declined my job because clearly it was something that they are not skilled at repairing. Please save yourself multiple headaches and just go elsewhere. read more

I was told by my neighbor about L&B and call them for service/ estimate on full system. This is by far the best HVAC company in northern VA And MD. There price is very reasonable and they know there stuff! Had an issue with my AC and they came out that day and tried to fix it but it was not worth it for me to fix the 20yrs old unit so I decided to replace it. I got few estimates just incase but L&B price was the best with best warranty. If your in NOVA or MD area don't even waste your time and go with L&B. Thank you guys! read more

Mike and his crew was awesome. Came on time and was wearing the mask due to Covid 19. They were professional and completed the job safely.

Outstanding! My AC went out on a hot August day. Michael K. provided a same day quote $4000 less than competitors. He advised me that it could be 1-2 weeks before they could get the HVAC system due to COVID supply chain limitations. Within days they located a unit and drove 2+ hours round trip to pick it up. Young, Johnnie, and Choi arrived on time, wearing masks and did a fantastic job installing the HVAC system and a hot water heater. All around, a great experience -- my choice of Lennox or Carrier system, no up-selling, under-promised and over-delivered on schedule, and professional install all at price that couldn't be beat. Highly recommend! read more

L&B Universal just installed a replacement HVAC system for my condo located in Bethesda, Maryland. Just wanted to say Jake with L&B Universal gave my the confidence that this was the right company to go with and quickly got an estimate together since the weather was getting hot fast. The pricing was reasonable and was able to find the replacement system QUICKLY and within a few days my unit was installed in a very professional manner. Thanks L&B Universal for a job well done! read more

I had a complete HVAC Lennox system replacement by L&B this week after researching systems and vendors for 2 weeks. I received 8 quotes during this time. Although I had lower-priced quotes from other local vendors, none would compete with L&B in expertise, flexibility and taking the time to educate me on the options. Jake patiently explained each option, provided pros and cons, compared different systems and continued to answer trail of questions during my research. This was my second purchase of a complete system from L&B so I had a high expectations and they did not disappointed. I am grateful for the AC/heating system I now have, the craftsmanship and professionalism of L&B crew from research to completion. read more

L&B continues to give 5 Star level service as they provide routine FREE service for two years following the installation. My highest AC/electric bill last Summer was $101 in August 2014. read more

I got quote from 3-4 guys. Jake/L&B gave a competitive quote for my HVAC installation. They did a great job installing and clean up after that. read more

We have done a significant amount of research on home central HVAC systems and experiences from home owners who had their HVAC replaced by going on-line as well as contact many of our neighbors who have got their HVAC systems replaced. We received multiple quotes from some of the highly rated HVAC contractors as well as the recommended HVAC contractors from our neighbors. L & B Universal is by far the lowest price contractor with exceptional service and response time as compare to ALL of others contractors that we get quotes from. Our sales person, Enrique is very pleasant, knowledgeable and patience in working with us in selecting our HVAC system and related HVAC options. We asked many questions that we learned from on-line, working with other HVAC contractor and our cooling preferences based on our house as well as all of the electronics that we run in the house. Other contractors were at least $1500-$3000 more than L & B Universal. L & B Universal service include a two years maintenance and five years labor which others do not provide. The installation of both HVAC units were extremely fast with a crew of four, each working one unit. Three trucks came to do the installations and it took about 6-7 hours. Everything was cleaned up after the work is done. Everything was done very smoothly as though they were not there. HVAC systems registrations and most of the paperwork are completed by L & B Universal. The technician provided maintenance training, manuals and all paperwork. Easy and pleasant experience. Invoicing was also an easy process where everything is done and we opt to receive them via email. Some extras that we selected based on recommendations. The inside evaporator coil (inside) is sized a little larger than the condenser coil (outside) and provided a little more efficiently and cooling for us. The basement/first floor gas heater was sized a little bigger than the attic unit since heat rises and more heating is needed on the lower levels. Our outside refrigerant line set had many transitions, bends and is old so L & B Universal replaced them from the outside units to our wall. Our thermostats used to take batteries now power off the HVAC systems really saving our concern about replacing thermostats batteries. We looked at some of neighbors that had their HVAC systems replaced and noticed that they paid more and did not get some of the quality work that is done by L &B Universal such as new line set due to transitions and 2 years maintenance. These neighbors are paying higher premium with no added values. A few contractors even said that there must be something that we will be billed during the installation process since the price is low, but everything was very smooth. We highly recommend L &B Universal for their pre-sales process, workmanship, price and friendly staff. read more

This company provides very competitive HVAC pricing. I had a Carrier furnace & AC replaced. The crew of 5 guys were professional, efficient, and seamlessly coordinated the attic furnace install with the outside compressor install. They started at 8 am and finished by 1 pm. I was very impressed and would highly recommend! read more

This is the worst company. Alex told me a part would be in the next day and it took 4 weeks. Then Alex cancelled 4 days in a row. I would never recommend this company. read more

Not a good company to deal with! L&B provided me with a defective HeatPump system on a $6k investment...They did not do a QA check on the system before it was installed with bent fins and defective coil. Kim Sandy is a very very rude person to deal with and there are several 5 star rated reliable HVAC companies in Northern VA area unlike L&B if you need to buy or service your HVAC system - I have given this a lot of thought and I do feel that this review is justified and fair..L&B does not deserve even a star!! read more

I usually don't write reviews either, unless it was a bad experience...but L&B Universal knocked a home run out of the park w/ their service! All the other posters are correct here....Alex and his team are awesome! I got a same day estimate and Alex gave off a very favorable impression. Not pushy at all in terms of salesmanship and also very informative by providing different options. We had a few other quotes and it's pretty crazy how some people can charge so much more for the same exact unit....I took a chance here based on the positive feedback and my overall first impression feeling. Also the pricing was the best that we received on the same unit. Upon doing the work, a whole crew showed up on time and went right to work. The people that come into the house wear the booties to not dirty the carpet and also lay down painter's plastic, tarps and painter's cloth. All the interior is protected....no kidding, at the end of the day, I didn't even know they came through the house for such a major project. We had a heat pump outdoor replaced and the furnace in the attic replaced. Due to the size of the opening, many pieces had to be disassembled and reassembled, but everything went flawlessly to my knowledge! The unit works well thus far (knock on wood)....but L&B offers a very nice warranty package included, so at least I'm protected....also they take care of ALL the required paperwork and I must say, communication via email w/ Sandy, was amazing. I was informed of EVERYTHING that got filed and was forwarded on the confirmation letters. I felt compelled to write this review because: 1. I was so impressed by the service received from L&B Universal. 2. I also want others out there reading the very little reviews on L&B, to have faith in this company and that they will do you right. The price, service, professionalism is TOP NOTCH! I will not go into details of pricing, but if you get a few quotes, make sure you include L&B as part of your free estimates.....you won't be sorry if you go with them. Now we are considering changing out the other AC unit as well sometime w/ L&B again....Thanks Alex and crew!!!! read more

We have worked with Alex and his team for more than 3 years. We replaced the HVAC and water heater with their company. Their price is reasonable. They came on time, and worked very professional. Really recommend this company! read more

The process of choosing the right contractor was long and tedious. My wife and I have evaluated (9) quotes for this job (Big business, Small business, local, and outside the area)....we selected L&M Universal, Inc. for this job. The hard work in evaluation quotes paid off as L&B Universal turned to be an excellent choice. At the beginning we thought L&B were the best contract based on cost alone (lowest quote), but quickly realized during installation and afterward that we have chosen the best contractor not only based on value alone but also on performance, maintenance, and "overall" value. Our Carrier Infinity 2 stage 19 SEER heat pump system cost less than $8K ($2K to $3K Savings) when compared with the next closest quote (Cost), installation went perfect, on time arrival, an army of professionals arrive to prep. the area and watching the team at work left me with the impression that they are true dedicated experienced professionals, and at the end I was surprised that QA and final check list was performed by the company's owner "Bruce" (performance), also we were given two years maintenance and service free of charge and in conjunction with manufacturer warranty we were given three years labor warranty (maintenance & value). I certainly will recommend L&B Universal, Inc. to all my relatives, friends, and co-workers. L&B thanks for a great job, you guys are the best! read more

We hired them to put the HVAC in our addition and everything was not smooth. First, getting them to show up on time or on the date they said was always an issue. Secondly, they would often say they were coming and then change when that was. The day they put the heat pump in they chain smoked all around the house while doing it and I was left with 7 cigarette butts in my yard and one in the addition (!) and a pack of cigarettes lying out front that my 3 year old later found. :( In general, they did not do a good job of cleaning up after themselves. They also delayed the home inspection process by not doing something that any HVAC company should have known was necessary which is to put in access to the unit in the ceiling with a pull down step. Finally, communication is not their strong suit. It was often like a whose on first episode until the bill was due...then they were seemingly on top of things! I would not use them again. There are a lot of HVAC places in northern VA, and this isn't one I would suggest. read more

L&B did a fantastic job installing a Trane heat pump for us. We have used three other highly rated HVAC contractors in the past 2 years and L&B was by far the best in terms of quality of work done, equipment selection, price and no-hassle factor. The installation couldn't have gone better, and L&B took care of warranty registration and rebate application for us. Their price was also significantly better than the other four bids we received on this project. Highly recommend. read more
