My water tank sprung a leak and I had water in my basement. I knew that I needed a new water tank. I contacted Mulco and they immediately sent over someone to assess what needed to be done. The next day four men came to start the process, starting early in the morning as they promised. Two of them left after the new water heater tank was in place and the other two remained until it was functional and tested. In total, it was 7 1/2 hours of work. I had not used Mulco before, but I will certainly use them again, as I know I have upcoming projects relating to replacing a toilet and a faucet. I recommend them totally.

Mulco has serviced our second home plumbing needs with excellent reliable, fair priced service for several years. But, recently-one of their workers did something wrong accidentally-costing us replacement money that we only realized seven months later. They checked the damage and immediately accepted full Responsibility and made a 100% fix of the problem. What a reaffirming pleasure it is to see such honesty, integrity and responsibility in todays world. Many of our neighbors use them and we will now tell everybody- Please use these people who have such old fashioned pride and upstanding character in their work and service. Fred G.

Thank you so much, Fred, for your incredibly kind words and continued trust in Mulco over the years. While we never like to hear that an issue occurred, we firmly believe that standing behind our work and taking responsibility when something goes wrong is simply the right thing to do. We truly appreciate your understanding and the opportunity to make it right. As a family-owned company celebrating 50 years of servicing the East End of Long Island, honesty, integrity, and pride in our work are values we work hard to uphold every single day. Hearing that reflected back from a longtime customer means more to us than you know. Thank you again for your support, your recommendation to your neighbors, and for allowing us to continue servicing your home. We sincerely appreciate you! – The Mulco Team

Overpriced | $1,000+ Hired them to replace 4 Google nest thermostats with ecobee that I supplied. Claimed it took 3 hrs + a $250 service fee. One of them wasn't working called them back the next day. Apparently the tech wired it wrong also told me I needed a new damper. Mine was only 7 years old. Asked him the cost he said a couple a hundred dollars. He game back installed the damper then with ever seeing a bill charged my credit card $1864.00. After I complained he removed the $250 service charge for coming back to repair the thermostat that tgey didnt wire properly. He said saw no problem and it was fair to charge me $800 to install 4 thermostats that I supplied and already had wiring. BEWARE if you use them expect to be considerably overcharged!!!!!

1/7/26: The customer contacted us to replace 4 Nest thermostats with homeowner-supplied Ecobee thermostats. During this visit, the customer also reported that the upstairs was getting excessively hot. Our technician connected the Ecobee thermostats to the existing wiring; however, the living room zone required a complete rewire. (These thermostats are not plug-and-play devices.) Once wired, all 4 thermostats required configuration and testing. This visit took approximately three hours, which is verified by GPS tracking on our service vehicles. There was no $250 service fee charged for this visit. The total charge for this call was $800. The following day, the customer called to report that the master bedroom was not meeting the set temperature and had dropped to 58 degrees. We returned promptly and found that the thermostat needed to be reprogrammed. It was not wired incorrectly. During this visit, the customer again reported that the upstairs was very hot. Our technician determined that the second-floor damper motor had failed, causing it to remain open and continuously deliver hot air. A replacement damper was ordered. While you state the damper was seven years old, zone damper motors typically last between 5 and 15 years, with 5–7 years being common for systems that are frequently used. Our technicians do not quote pricing in the field and are not authorized to do so. On 1/14/26, we returned to replace the damper. The material cost was $360, and the visit took approximately 1.5 hours, again verified by GPS. This invoice mistakenly included a $225 service call charge for the previous visit, which should not have been applied. When this was brought to our attention, we immediately advised that the charge would be removed. The corrected balance for that visit was $687.02, including tax. Our credit card policy is clearly stated on all invoices, “All Open Balances Over 15 Days Will Have the Credit Card Automatically Charged." In this case, the card was charged after 9 days, and 1 of the 2 invoices was not received by the customer. We acknowledge these errors and appreciate them being brought to our attention so they could be addressed. To account for these issues and the inconvenience caused, we issued a $664 credit, reducing the total charges from $1,864 to $1,200. This adjustment reflects the removal of the second service call charge and a reduction to the overall cost of work performed. We value all of our customers and appreciate the opportunity to address concerns and make corrections when needed.

I would like to amend my previous review. After several conversations with Mulco, we were able to arrive at a mutually agreeable solution. Mulco reordered my HVAC compressor and repaired the system satisfactorily. I am appreciative of their services. I look forward to working with them in the future.

Mulco is fast, honest, knowledgeable, professional and polite. They did great work on two different plumbing projects for me. On both occasions, I was out of town and they met my brother at the house in a timely manner and solved our issues. I highly recommend to all.

Mulco's office staff has always been prompt in handling my calls, promised call backs and follow ups. The service men have been thorough, knowledgeable, and pleasant to have in our house. The company also was very kind when I requested help with a friend who is on social services. They couldn't have been kinder.

Terrible experience with this company. They installed a new air conditioning and heating unit in my co-op last August. When I turned on the heat over the winter it was not blowing hot air. When they came to check it they said I need a new coil. This is a brand new unit so they said I need a bigger coil. I have since called them several times to talk to someone to see what I need to do only to be told someone would call me back within a day or two. I have not heard back from them as of yet. I would never recommend this company. Negative Responsiveness, Professionalism, Value
