Owner & Management were very helpful in redesigning our Hydronic Boiler/Heating system. Bids came in promptly as promised. Installing techs were prompt, profesional and informative. Highly recommend ASP based on this and past experieces. read more

We had a problem with our AC. It took several weeks to get to us and then they said it was a bad compressor (on a 1 1/2 year old Amana AC [done buy Amana]). They ordered the parts and it took weeks to get the parts and do the repairs. About a week later it sounded like it was going to blowup. They came back out, said the coolant was not vaporizing and the filter was to thick. Stuck a filter in that they had on the truck and said they would figure out what needed to be done and come back and to put in the correct filter. That was almost a month ago and it still isn't fixed and they keep putting us off. read more

After 5 weeks of calling me and cancelling each day to do my two ceiling fans, they finally left a message that they do NOT service my area. What a rotten company. Jean SS ZERO STARS read more

I had an appointment for service on my air conditioner on Tuesday and waited all afternoon for someone to com. It was about 4 pm and I had plans for the evening and no one could tell me if they were coming so I rescheduled for Thursday afternoon. Same thing, its 4 pm and no indication anyone is coming. They use AI to text updates. So I called and not sure if I talked to a human or AI. Someone was supposed to call me. At that point, I felt like no one was coming and was going to cancel. Then AI text came at 4:30 pm that someone was on their way. Meanwhile, someone called from their office that my monthly payments were not going through. Instead of paying cash once a year, you now have to subscribe for their services. I checked my credit card and charges had been posted and paid to them. This place is all screwed up. A technician finally arrived at 5:30 pm. He was friendly and knowledgeable. I had no issues with him. Sadly, this long time customer has had enough. Very poor customer service with no human interaction to resolve scheduling and financial issues. read more

Called to request a service mid-day and ASP was here before dinner time! They assessed the issue, gave me multiple solutions and recommended a small piece be fixed as preventative maintenance. That small fix could have prevented big problems for us in the future. The gentlemen were kind, fast working and so kind to my kids. I would recommend ASP to anyone in the Duluth area in need of repairs in a speedy timeframe! read more

This is the second time we have used ASP so I called them again for a different issue. In the morning, I noticed our toilet was not flushing properly. We suspected it was the septic system. I called ASP and spoke with Barb. She was very friendly and very helpful. She said she would call one of her drivers and called me back. Barb stated Zack was working the area and would be there in a couple of hours. Zack arrived with his truck. Zack was very knowledgeable and friendly. He inspected our septic and found a filter not in place. Not only did he clean out the septic system, he repaired the filter. We appreciate the professionalism and speedy service of ASP. We will use them again. read more

ASP was hired to cap a refrigerator water line ON THE SECOND FLOOR OF MY HOME.. An hour after the plumber left I found water coming downstairs. I called the after-hours emergency number and was told to wait until the next morning. The next morning the water filled my kitchen ceiling. An emergency water service company removed part of the water-damaged sheetrock ceiling and cleaned up the water damage. ASP wanted me to pay the emergency water repair company instead of taking responsibility for the damage left by their plumber's failed work and failure to come back the same day to fully shut off the water supply to the refrigerator. Management was extremely difficult to work with. Sakouna from Duluth read more

We are very pleased with the staff, service and prompt response to any issue we have in our home. We have hired ASP for multiple projects since renovating our home 2 years ago - plumbing issues, HVAC projects and last fall a new mini split system install. They always do great work, show up when they say they will be there and have the most friendly and knowledgeable staff from scheduling to field techs. we highly recommend ASP. read more

Wade, the plumber ASP sent out is the only reason I am giving this business 3 stars. Otherwise, I would give them less. Wade was personable and did a good job fixing a busted water pipe and extending our outside water hose closer to the garden. The office and dispatch were horrible and deserve zero stars. Everything began on Friday with the plumber scheduled to be here between one and four. He didn't have the part he needed, and it was too late for him to get it and come back. Dispatch scheduled a technician to come out on Monday between 8am and 1pm. No one showed up. when we called, the woman in the office said he would be here "soon". When we called again, the woman said he can't make it today. He was supposed to return Tuesday. Another no-show. We called several times Tuesday and were pretty fed up by then. Her response was "sometimes its just the luck of the draw," which is not the way to run a business or create loyal customers. We insisted he come Wednesday morning, which he did, and he did a good job. The woman in the office and the dispatchers lied to us several times over several days. So frustrating . read more

Incredible service! Joe and Trevor were a delight and they switched out my kitchen sink and faucet with new I had purchased. these are professionals you can count on! read more

Terrible to work with. Used them for a simple service on furnace and water heater. After the work I have water left on my basement floor. Next morning more water. Did did come out again but want to replace my heater for $2000. Not willing to take any responsibility. I did visit them at the office and asked for a compromise, no help. I will look for some legal help today. read more

Excellent service fast and professional but a bit spendy. We had a single pex pipe replaced (maybe 4 feet) and the job took 30 minutes. I don't know if Yelp filters out $$$ but the bill was between four and five hundred dollars. Seems like a tad much. read more

I have been using ASP for over a decade now -- they were recommended to me by my real estate agent. I have nothing to say but good things about the organization - helpful, friendly, reasonable prices, and PERFECT work done. They suggested solutions and options to fit my budget. Now we've signed up with their annual 'check up' service which comes with a lot of cost saving incentives; like plumbing insurance! Love it -- and love ASP! read more

I am now a super fan of ASP. Smart, fast, and modern outfit. I specifically worked with Caleb across a range of projects. ASP was busy but were able to manage their team effectively to get to my projects in a way that felt well managed and considered my situation. The work was professional, detailed, and thoughtful. It was easy to understand options and costs, and they have online estimate approvals and payments that makes managing all of that easy. Great communication all the way through. I have worked with many contractors and will hire ASP every time I have a need for plumbing, HVAC, etc as it is a well run business that does excellent work, and the crew was full of very nice people that are fun to work with which is always a bonus. read more

I give three stars because of how quick you responded, how friendly you were, and for leaving us with 4 space heaters for a couple days. Other than that, because I'm a female you tried telling me I had 2 options one being buy a new furnace or the second being replacing the part for a few hundred less than a new furnace. It's the landlords decision not mine, and he Still just wanted just the part ordered and ASP was supposed to be at my house the next day at 8am installing it. A little after 8, we get a call telling us to drop everything we are doing if we care about our house and buy a new furnace now. Then continued to say they misdiagnosed it, etc, etc. I felt not only they were unsure of the diagnosis but also felt preyed on. With how pushy he was being about financing a new furnace made my landlord and I feel so uncomfortable that we asked another company for a second opinion. The second company showed up an hr later quoted around $500 and fixed it on the spot!! Left extra filters and it was something to do with the blower!! No one likes feeling taken advantage of and it's to bad because you've already got our business twice now. We thought you were an honest and nice company. Won't make this mistake again! read more

I had no hot water for a week without turning my heat on high, in 85 to 90 degree heat outside. Made the call to ASP and they came in 2 days. Reid the tech was the first person to look at my system and not be totally confused. He explained how my system works what probably is the problem (and it was the problem), how it was supposed to work , what it would cost and how long it would take to repair. Perfect and than made some suggestions and adjustments as well. Couldn't be more satisfied. REID is his name. read more

Edit 2- About 2 months after their mistake, they rectified it. I received multiple calls from the president of ASP apologizing and explaining how they would make it right. I received a refund, and a complimentary heating tune up. From my perspective, they fully corrected their mistake, and that's all you can ask for. CHOOSE A DIFFERENT COMPANY! TLDR: They knocked out my heat in the middle of winter and charged me $200 to turn it back on. I hired a plumber to verify that the tankless boiler in our new construction house was converted properly to use propane. The plumber left without turning the gas back on, which caused the unit to get an error code and stop working. This knocked out our hot water and our heat. I didn't notice immediately that the heat was knocked out because it's radiant in-floor heat, which takes a very long time to cool down/heat up. I spent 30 minutes or so on the phone with the plumber to clear an error code (004) on the unit, which was caused by it trying to start with no gas supply (recall he left the gas off when he left the job!). Finally, after clearing the error code, we have residential hot water- little did I know that the code also had to be cleared on the radiant side of the unit, so my heat was still out. I became certain that my heat was not working about 36 hours after the plumber knocked it out. They sent a different person, an HVAC guy, out to see what the problem was and determine if it was their fault. Even though he had to clear the exact same error code (004) on the radiant side of the unit, he said it was not their fault, he cleaned an ignitor, and had to charge me $200. I paid him after a little bit of arguing because I realized I shouldn't waste his time with it. I called the office to explain the situation to them. The office lady insisted it was not their fault, she could not refund my money, but I would receive a call from the department manager. It has now been 3 weeks and I have not received a call. This whole fiasco was created by a plumber not verifying his work- he left without turning the gas back on! So he obviously could not have verified the system was working when he left. Making mistakes is fine- everyone makes mistakes. But to charge your customer $200 to fix your company's mistake? Despicable! read more

Called for a laundry basin installation and was told they could have it all done Friday morning. On Friday, I got a call informing me that they could only do an inspection and estimate that day, but they would make an appointment for 9am the following Wednesday (today). The plumber didn't show up and I called the office at 9:30, only to be told there was no appointment. These guys need to get their acts together and get a new secretary! I have too much to do to have my time wasted like that. read more

We had Summit Mechanical come to our home in the beginning of May to give us an estimate regarding the installation of a semi-split air conditioning system. The sales person said they would send us quote by the end of the week. On the Monday following, this was the email I received: "Thank for having Summit out to look at you A/C project at this time Summit will not be providing an estimate." That's it. When I responded and stated that I had never heard of such a thing and asked why - no reply. Their email was incredibly unprofessional. I will never do business with Summit Mechanical company and cannot and will not recommend them to our friends. We had Carlson Duluth instead. Two days, beautiful job, wonderful people, highly recommend Carlson Duluth. read more

ASP came to Dallas Texas after our winter storm to help with plumbing issues caused by the storm. I scheduled an afternoon appointment, no one showed up or called. At 6 pm I called them not to come that evening because I had to go to work, I called them back in 2 days to reschedule my appointment. I scheduled for Saturday 2/27/21 at 4:30. Rory text message me AT 2:26 wanting to come at 3:00 pm. I did not see message until almost 5:30 pm. By that time I had spoken to Trevor who stated that Rory had told him it was a bad neighborhood and he was afraid to get out of their car. I informed Trevor nobody had been here. Trevor said he would ask another tech to come on Sunday or Monday or he himself would come. On Monday my calls went to voice message without a return call. Monday around 10:20 I called Rory, again he repeated he did not feel safe. After talking to him I got a text message from him saying he could not talk because he had just had oral surgery. Dallas Texas beware if you do not live in a rich white area of Dallas ASP will not do the plumbing work for you. read more

Quoted about $400 initially for sewer tank pumping. After the office conferred with Zack the price jumped to $560! Insisting I had a septic system. Business demeanor is unprofessional... I did have a local reputable contractor pump my holding tank for $175! Don't get ripped off. read more

I had a leaking pipe that created a big mess. I called this company and they were here in 10 minutes, fixed the system to stop the leak and came back the next day to replace the pipe. They checked all of the pipes, found another leak and saved me from another disaster happening. I would highly recommend this company. They were amazing! They really are as good as it gets! read more

So, after having them in to diagnosis the problem we were told that it was our pressure tank. After replacing the pressure tank the issue that we were having was still there. We then had to call a well company that knew within 10 minutes of being here what the problem was. Within 30 minutes had the issue resolved and was back out the door. To say the least it has been 2 months since this happened and I finally received the bill. After talking to the manager about the misdiagnosis they were not willing to do anything to help compensate the bill or pay for the price of the pressure tank that we replaced on their advice. I would not suggest this company to anyone. read more

My contractor brought in ASP Plumbing to rough plumb a new kitchen, laundry, and bathroom for a small addition to my home. It thought these guys were great. They came in and immediately started by reviewing the work scope with me. Then they got right to work, with no fooling around, and were completely done in just a day and a half. The plumbers were kind and respectful and did good clean work. These are the guys I'll be calling in the future when I need a plumber. read more

They responded promptly to our need for a waster heater, gave us different options and quotes and performed the needed service all within 24 hours. We would definitely recommend their friendly, competent service. read more

the tech was respectful but was unable to fix the problem since he didn't have the equipment on his truck to fix the problem, for 350 dollars for just to come out and look at the furnace really should have the right gear on truck specially for winter times. read more

I used ASP for a new house build. Numerous mistakes (toilet plumbing placed in the garage instead of the bathroom). Leaking toilet connection (of brand new toilet install) flooded the bathroom and ran under the wall into the adjacent room ruining all the new flooring. Water lines ran outside the studs. When management questioned they stated it was hard to find good help. WOW- really? $15,000 for plumbing and I had to pay another contractor to fix the mistakes. read more

A year later and still having issues with the work they "completed" after their poor workmanship, lack of communication, slow efforts, and hack job ok heating. I honestly can't believe the horrible job that was done by this company and the lack of communication received. Do NOT use this company! Hire at your own risk! If you feel like babysitting adults you're paying to do work, then this is the company for you... read more

I originally called another plumber who clearly didn't want the job. These guys showed up on time and got twice the amount done at the same price the original plumber quoted me. They worked quick and did the job right. Great work ! read more
