    It is not the easiest unit to access and service, but I usually go up there and Haile shows me what is wrong.

    Best service! Found them on https://dmvprofile.com/ -- fast and professional.best serviceread more

    I read the reviews and saw the pics and was feeling good vibes regarding this company. Let me start…read moreby saying that I was so excited when Earl informed me that I could receive same day service. I sent pictures, discussed the process, pricing, and even what to expect and how others prepare once the water was turned off. The men arrived on time, they were greeted and then proceeded to tackle the four hour project. After removing my system, I was presented with price gouging ...$350!! I was informed that the pipes would have to be replaced because my system was corroded! During this conversation, I noticed that the *meter was still in place!! Earl informed me that the *meter would be removed and reinstalled in order to get to the water heater out of the space; I was remembering that it wasn't removed with the prior installation. After sending multiple pictures, giving the year that my home was built, and believing I was dealing with exceptional professionals, I was not expecting any surprises. After being presented with an unexpected fee, I called Earl and he didn't take responsibility for not informing me that there could be a chance that the condition of my pipes could be an issue ... at this point I'm remembering to breath and just asking Jesus to take the wheel!! "Supply and install new manufacture required expansion tank and relief valve vent tube" was included in the initial proposal. Looking at the before and after pics, the condition of my pipes was not an oversight! Please be careful and request an itemized statement with the proposal b/c Earl informed me that b.c the *meter was not removed, I received a credit and only owed an additional $100 ...what a shame. Thank you to the men who did the work and left my home spotless!! Blessings.

    I was in need of second-opinion and consultation regarding a leaking HVAC unit. I wanted to make…read moresure the leak was difficult and too costly to repair, and whether a new installation is advised. We discussed on the phone for a long time what the issues were with the hvac unit. He listened carefully to the whole saga of the hvac unit and laid out the various options he thinks I have--all this before being asked to work on anything. He went over the details of the tests he could run and answered every one of my dozens of questions. He answered my texts throughout the day and night. He made time in his busy schedule (squeezed in my appointment late in the day and had to work late) to run another leak test that I asked him for. He gave me the assurance I needed, not to mention a very fair pricing for the urgent leak test. Carlos is the most trustworthy contractor I've ever worked with. I appreciate his time and caring through the process. I can't recommend him enough. I figured this is the least I could do in return for his help.

    I have used C and V Home Services since 2022 and will keep coming back when something goes wrong…read more First let me say I am a client that don't do the preventative maintenance (LOL). Carlos is straight forward with information and offer fair pricing. C and V Home Services stand behind their work with warranties and quality installations. I am in the process of getting an HVAC upgrade and C and V Home Services will be contacted for the installation. I told Carlos about my project and he explained how the HVAC part would be assembled and the various options I have to choose from. If you are looking for value, honesty, and quality work then look no further!

    I posted this on Friday but it's miraculously disappeared…read more Spartan is, out of 40 years of homeownership, by far the worst one I ever worked with. All of the negative things other reviews mentioned are true, and then some. I won't even get into all of it because I will probably just keep posting this as it may mysteriously disappear again. Let me just say: they don't know what they're doing. I needed a sewer line blockage removed; they suggested replacing the entire sewer line to street. I could see it was corroded but as I saw the lack of progress and hopelessness of ability, I told them just fix the blockage in one pipe and that's it. (I leave aside the first 2 guys jackhammered in the wrong place to begin with. They work 4 hour days, including a break and lunch and arrive anywhere from 9:30 to !0:30 or 11. After, the basement was a disaster; they didn't clean up the sewage around the drain, sort of mopped the floor, ruining the mop, but because they'd left all the debris over the weekend the floor was quickly filthy again. And, the simple thing unclogging the line out of the laundry tub wasn't done, though they told me it was. Bossman called me in the afternoon after they'd been here 3 days (around 12 hours total) to tell me they were going to charge me for part of what they didn't do "because I changed my mind." I protested and he literally shouted and shouted and shouted until I simply hung up. As I said in the disappeared review: stay away. There are good plumbers out there. "Spartan" is not even close. See how long it takes for this to disappear.

    I am writing this review after our 3rd canceled appointment. We have a leak, had them come out and…read morediagnose the problem. After the initial appointment they scheduled the repair. Then ghosted us. Then we rescheduled, then they ghosted a 2nd time. So I called and confirmed a time when they could finish the job, but again, they cant make it. We paid: 08/29/2024 SPARTAN PLUMBING HEATIBRENTWOOD MD USA $444.00 for holes in the drywall, no fix, scheduling hassles, and it's still leaking causing damage. I will request a refund
