    Ricardo patiently explained what the problem was, why I wouldn't have working AC after he would leave, and what my options were.

    We hired TNT plumbing to address a leak on a vent pipe that appeared beneath our master bathroom…read more He canceled the first day and charged us $175 (this price includes a $20 discount since he had to cancel). He mentioned they may only be able to do the consultation since they had another job, so from the very start I felt like we were receiving rushed service. Dan and his apprentice spent a little less than an hour knocking holes in our drywall (in one closet he just started hitting the wall with a hammer) only to make his way up to the attic to tell me we had a roof leak. As I had mentioned in my original consultation, this was in fact a vent pipe leak that I would have been happy to pay to have addressed. Instead, we went through two roof consultations before I crawled up in the attic and fixed the vent pipe myself. I tried to reach out to Dan to let him know this was actually a plumbing issue and received no response. We found TNT through one of the Yelp project requests and I deeply regret choosing them as opposed to some of our other options. Between the price paid, the lazy investigation of the pipe, and the lack of response when I reached out to have the situation rectified, I am seriously disappointed with their service.

    Dan was really responsive and explained what he was going to do. He showed up on time and finished…read morethe work in less than 2 hours. Before leaving, Dan made sure that I knew where all of the shutoff valves were located and made sure that I could adjust them, as needed.

    I reached out to Yelp in February due to the safety overflow valve on my water heater leaking. I…read morereceived an immediate reply from khuma with Ebenezer Plumbing and Drainage, who offered to come that evening to deliver a free estimate or the next day if it was more convenient. We set up a time to meet the following day. The next day Khuma texted me when he was in route and arrived on time with his assistant, They both put on shoe coverings before entering my home. After taking a look at the heater he assured me he could check several systems to find the culprit and gave me an estimate. The work was completed in about an hour. He then showed me the various systems he had checked as well as the results. He ended up placing a new valve on the overflow system. He cleaned up the work area when he was done. He also took $50.00 off the quoted estimate and charged me $200.00. I found Khuma to be polite, and concerned. The quality of the work and the knowledge he demonstrated in the type of water heater system was impressive. He even quoted the amount to replace the entire system. I placed his name in my call list under plumbers in case I would need future help. I would definitely recommend him for anyone needing help with a plumbing issue. LB Feb, 2026

    Saved by Ehrhardt Brothers Quality Plumbing! (West of Baltimore, a.k.a ColumbiaPlumber)…read more Sunday evening, our water felt less hot than usual. Monday, it was only as warm as we keep the house, and only as much water as there is in the pipes! Our gas water-heater failed! Bad timing, too. Last week was what Chicago calls Fools'-Spring ... around 70°. But this week was back to Second-Winter, 30° (Mar 2026). And the next warm days, which Chicago calls the "Spring-of-Deception", is still ten days away. There was water leaking from the heater. This is considered the calm before the 50-gallon tsunami. If this is home-remedy advice, First call a friend who has successfully navigated this problem. Next shut off the gas and then the pilot. Next shut off the water inlet. Your friend will have at least one plumber to recommend. (They will enjoy that...) If your garden hose isn't frozen to the spigot, drain the water tank. If frozen, spend a sleepless night with the 24/7 plumber's number on speed-dial. We chose #2.  We made it through the night. Two of our friend's recommendations were small-businesses, our preference, and we asked all three for quotes and availability. Ehrhardt was ready to offer a price based on our descriptions and photos, of course with caveats for anything unexpected. I considered their bid to be a pretty-penny, but I'll say it was less than our friend's expectation, and more than our friend in Cleveland expected. A fair price. They came the next morning, and it might have been sooner if we had called right away. We cleared a path for them through the house, and they had the water heater replaced in 90min. Impressive. We went out for St. Pat's. But what we should have done was what they told us: check the pilot light for about 30min, and test the hot water after 60 to 90min. We came home to cold water. I'll admit some grumpiness. We called in the morning, and they came back in a jiffy (our apologies to everyone else who had appointments that day). In 30min, they figured it out: a faulty pilot in the new, just-unboxed water heater. They had a replacement part over-nighted. The next morning, in 30min, done. This time we did as told: checked the pilot after 20min (and nervously, an extra time again after that). Still lit! The second time we checked, the hot water outlet was noticeable warm. By 60min, hot water from the faucets! By 90min, much to relief of nearly everyone i know, a piping hot shower. AAAAAHHH :-) Ok, so how does three visits equal 5-stars! The hardest question answered first: Because the problem was the manufacturer's fault, and Ehrhardt handled it flawlessly: Excellent communication by Ehrhardt, priority attention to our problem, no excuses, just fast resolution. Great service staff, from the office to my house. Fair price. I admit that I'm writing this in the after-glow of that hot shower. This could be the start of a beautiful situationship.

    One of my two AC condenser units that cooled our bedrooms and loft stopped working last night in…read morethe midst of a heat wave right before the July 4th holidays. Thankfully our other AC kept working so we all slept in the living room while we waited for the morning to come to call around for HVAC companies that could come ASAP. HVAC Direct was the first company I contacted and Scott came within an hour of the call and got to work right away. And within an hour he diagnosed and fixed the problem (luckily just a shot capacitor) at what I thought was a reasonable price. Scott was super professional and friendly without being pushy with any additional products to sell. He also checked our other working unit just about of precaution. So grateful he was able to come and fix things so fast on the eve before a long weekend in the midst of a heatwave. Would def recommend HVAC Direct again to anyone and would use their business again!

    My husband contacted HVAC Direct Heating & Cooling after normal business hours concerning our A/C…read moreunit at our personal residence was ONLY blowing warm air!! Now the previous evening, my husband contacted a large local competitor to check our HVAC system. Technician from local competitor came out and looked out HVAC system, didn't test any components and stated "our compressor was locked & leaking refrigerant and quoted my husband $6k to replace it or we can purchase a brand new HVAC system for $25k!!!" (NOT TRUE!!!). The tech even left our outside power switch unplugged so we couldn't test the system!! SMH!!! We won't contact them for any service ever again nor recommend them to any neighbors, friends and family!!! Joe K, Service Technician at HVAC Direct Heating & Cooling contacted my husband within 20 minutes of him contacting the office the next business day and scheduled a visit that evening. He came out to the house, checked the compressor and quickly diagnosed the capacitor as the problem & replaced it. And Joe K. even showed my husband how he diagnosed the capacitor as the issue NOT the compressor leaking refrigerant as stated by local competitor!! No refrigerant leaking at all!! Compressor in good condition!! In addition, Joe K., checked the wiring, fan, all associated parts and cleaned our a/c unit. No issues at all!! Just some cleaning needed!!! HVAC in excellent working condition AGAIN!!! In addition, he checked our furnace, cleaned some our internal components and showed my husband some DIY things to do to maintain our HVAC system throughout the year!! Amazing work & Professionalism by Joe K!!!! I returned home from business travel to a COOL & COMFORTABLE HOUSE!!! ALL Work completed in an HOUR!!! (less time than the large local competitor spending 2 1/2 hours trying to sell my husband a new HVAC system)!! Joe K. was amazing, excellent communicator, knowledgeable and very professional!! Highly recommend HVAC Direct Heating and Cooling!! Great Pricing for Service Plans & Parts, Excellent Technicians!! You can't go wrong with Joe K. & Scott at HVAC Direct Heating & Cooling!! 5 Stars*****!!!
