"Fast response and excellent service! Our central A/C was fixed the very same day, and the technician clearly knew what they were doing. We were so impressed that we hired them again for a water heater installation?and they delivered the same level of high-quality, tidy work."

"Almost 2 years ago, Lee's installed a new heat pump in my house. The techs were great, and the installation experience was smooth. Unforunately, within a month, it broke down. During a hot summer in 2024, I went over a month without A/C while Lee's fixed it temporarily, only to have to break again. And again. Eventually, they pulled the new heat pump out and installed a NEW new heat pump. Again, the actual people coming to my house were great. The communication between the office, the techs, and the customer was shaky, however. It took repeated calls to get someone to come out to do repairs once they'd gotten paid for the system and were now just covering the warranty. It is now April 2026. In March, I came home to find water dripping from my ceiling vents and the heat pump malfunctioning. When I called Lee's, the rep on the phone tried to tell me "that is normal when the A/C is turned back on." Nope. I have been waiting over a month for the right part Lee's says is needed to fix i"

"We had a sudden spike in water usage two weekends ago. It was clearly from the water pipe attached to the sprinkler system manifold. I attempted to repair it myself, but the fix didn't take. I called Armstrong based on their reviews on this site. We set up an appointment for the morning (8-12) on the 26th; there was no rush for the fix as we wouldn't need to use the sprinklers for a while and shutting off the water to the sprinkler system stopped the flow. I received a text message on the 25th confirming my appointment for 8am-12pm on the 26th. At 11:55 on the 26th, I called for a status check on the technician. They had me on their schedule for the afternoon. It was confirmed that the text message I was sent confirmed the earlier time frame. They had no explanation for the error. Still not a major issue, but now my entire day was shot. The technician arrived within the time frame. He assessed the issue. It required a simply re-cementing of the fittings, but he wasn't sure it would work (outside temperatures, the PVC pipe itself, etc). He also didn't have the zip ties he wanted that would help secure the pipes while the cement was curing; I didn't have any, either, but I did come with an alternative that he found acceptable. He completed the work, and basically said that we'll have to see if it worked. The good news is that we have some time before I have to turn the water on again which will give the cement time to set. He did offer a quote for replacement of the entire sprinkler manifold as a permanent solution. Although I recognize there are variables in repairs and that it may truly need additional work, I was underwhelmed by the service received."

"Domco was amazing from beginning to end. It all started with Clarence who gave us the estimate. He was very professional. The team that worked on our pipes were Sean, Jody, Alfredo and Daniel. They were professional, courteous, friendly, and extremely hardworking. We had to have all our pipes replaced to due a leak and faulty pipes that were installed when the house was built. The team had to endure hours of working in our attic during the hot July days. They remained positive and helpful the whole time. This team and all the people we dealt with at Domco was very knowledgeable. They kept us informed and explained each step along the way to us. Dom leads by example he was very professional, honest, and fair. He inspected the job before and after it was done. To me that displayed his level of commitment to quality. I do not think I could recommend any company more than I recommend Domco. If you are looking for an awesome company for any of your plumbing needs do yourself a favor and call Domco."

"Excellent job! by Lorenzo, Service Technician"

"Office was very responsive. On the day of the appointment the plumber checked to see if he could come early... which was great! He determined what what kind of valves were needed and quickly purchased parts. He completed the work efficiently and was very helpful. Great results. Would hire again."
