Recommended Customer Reviews
Terri B.Highly recommend them! Heat went out and they came within 2 hours..they saved our bacon from a cold night!! Very nice, professional and reasonable!! Would definitely call them again if needed! Thanks guys!
Was referred by a friend. I called Tyson and he had me check a couple things. Wasnt an emergency. He called me Monday morning and scheduled an appointment that day. John and Rey showed up on time and handled the problem efficiently and very professionally. They were great!! I will definitely use them again!
I have used Duvalls in both a rental property I own and my home as well. Every time they come out I am impressed. They are respectful of my home and honest! I had a leak in my water heater in the rental property and I assumed I would be told I need a new one as it was quite old, but they told me they could fix it with a part that cost $1.00. We did go over what was starting to go wrong and that I should think about replacing it, but it didnt need to be done immediately. Needless to say, when the tenant moved out and the unit was empty, I decided to replace the water heater with Duvalls. Its very refreshing to not feel ""pressured"" into spending tons of money. I had a clogged kitchen sink at my home and again Tyson (who is great) discussed the problem and did what he could to save money. If you need any plumbing, I would definitely reccommed Duvalls as they are professional and honest!
I switched over to Duvall years ago when my AC went out during the hottest time of the year.
Instead of proposing I get a whole new system, the advised to replace the condenser, which saved me a ton of money and heartache. Ever since then I have called them in for plumbing and gotten very fair treatment/pricing. Their guys are really good at what they do and will even give you advice. I have referred them to other friends of mine and they are happy too!
Courtney W.I have used Duvall's now at 2 different homes. As a female, I love that I can trust knowing they are telling me an honest review of what is going on with my HVAC and a good price. Most recently, I had 5 different companies come out to review my Heat Pump, every single company told me completely different stories of what I needed, what was wrong, how much freon I needed to replacing the entire unit. I knew I should have just initially called Duvall. They came out right away, told me exactly what was going on, replaced the parts at a great price.
I had an EXTREMELY difficult to reach cast iron sewage pipe that needed replacement. Over two years, I'd had 3 different companies send out techs. Each one was a horror story of estimates and in one case (i won't mention them here) outright incompetence. But we couldn't put it off anymore and I tried Duvall.
The previous guys pretty much told me we had to rip down walls and one guy said we had to tear up our floors as well. So when Tyson said he could get to it without destroying my house, I was ecstatic. He was able to replace the leaking cast iron as well as old drainage copper with PVC for much MUCH less than the other guys. Probably because he wasn't trying to basically ask me to renovate my house to fix a leak. They did a great job, did it in one day, and after 4 months it's still holding up aces.
I'm trying to attach a photo of the pipe that got replaced.
Jason D.I live in Manassas and I had a pipe that was leaking slowly from a soldered joint behind my shower. I have never had to call a plumber before so I turned to yelp and this company had great reviews so I decided to give them a try. I called on a Wednesday afternoon and spoke to a very friendly receptionist who made the first avaiable appointment for Friday afternoon between Noon and 4pm. Tyson and James called me around 1pm on Friday and to tell me they were about 20 to 30 mins away from place. When they arrived they were very friendly and got right to work and made fixing my leak look easy. (See the before and after pictures I posted.) They charged me what I thought was a reasonable price and told me they guaranteed their work for a year.
I'm always weary when I have to call on someone for service. Many times they don't show up on time, try to up sell, or charge you for more than what you need. This was a very positive experience because these guys showed up right when they said they would and didn't try to sell me on things I didn't need to have done. They also gave me some free advice on a couple other plumbing issues I had questions about around my home. It is very likely I will call these guys again when I decide to get these things fixed.
Katy R.We've had Duvall out for all our plumbing issues and can't recommend them enough. Most recently Tyson was out to assess a leaky spigot outside. It definitely needed replacing, which he recommended and while cutting an access out of the basement drywall had me come down and explain/show me what he was doing. Knowing our house was going on the market, he showed me some places the siding could be sealed to prevent water intrusion since there was some dampness in the wall where the spigot was replaced. He let me know this wasn't work Duvall did, but just to inform me. Great guys to work with - I would definitely recommend.
I needed to replace a heat pump, an A/C and a furnace. I called Duvall's and spoke to the owner Mr. Duvall. I asked him several questions and he gave me the feeling that he ran a business that would serve me well. The next day, Jay came to the house and assessed the situation and provided me an email the next day with an estimate. I also called the company that i had been doing business for the last ten years and asked them for an estimate. This is a National Company. A spoke to a person on the phone who was inexperienced and misinterpreted my request....she was going to send not an estimator, but a technician the next day to service my equipment. I again told her I wanted an estimator and she set it up the next day. Well the next day, no one showed. So I called the office and spoke to their Service Manager and he admitted someone dropped the ball. So the next day, they did send an estimator. Well he was supposed to be an estimator but he was really a huckster. Before he left my house he said the cost would be 25% more than the cost Jay quoted me. Then he said he would give me 10% off because I was a veteran. Then he would take another 10% off because my wife was a teacher. Then he would take another 10% off because I was retired. I said.....just send me a written estimate. Then he says.....let me come by tomorrow with a contract for you to sign, I said.....just send me an email with an estimate. After 10 days or so, I never did get an estimate and I called Duvall's and told them they had the job. A few days later Jay came out and installed the systems in two days. The price was about where the national company ended up after giving me 10% off a few times. Could I have negotiated with Jay to have a few hundred dollars knocked off?......maybe.......but I was more than satisfied that I had found someone who was not out to screw me. Jay did most of the work himself, he was efficient and clean, he kept me informed where there was something i should know as the homeowner, he always arrived when he said he would and I am confident I made the right choice.
Our water heater started leaking on Sunday AM (we knew it would need to be replaced, as it was installed 17 years ago).
Searched on YELP for a plumber, and determined to go with a local-owned company. Liked what I read for Duvall's, and called their number.
I spoke with the agent, told them what we had, and figured out that we could be okay with current unit until Monday, so we didn't have an emergency fee (although they had techs ready to come if we wanted).
Called Monday AM and scheduled appointment for 9:45. They arrived (John, the owner, was the lead tech) with replacement unit on the truck, was quoted a reasonable price, and they got down to it. New water heater was installed by 11:00!
This was one of the best plumbing interactions I have ever had! I will not go anywhere else for any plumbing/heating/AC work in the future!
