Founded by Archie and Elizabeth McLay, McLay Services began when they moved to the U.S. from Scotland, bringing with them a dedication to integrity and a desire to assist the community. Initially, Archie Sr. worked for a company servicing HUD homes, which allowed him to gain extensive knowledge of the plumbing field. Eventually, he ventured out on his own, with his core values shaping the plumbing and HVAC business he built. His son proudly entered the family business early on, gaining a solid work ethic and the necessary skills to continue delivering the exceptional service customers valued. In 1999, Archie Jr. took the reins and upheld the integrity established by his father. Currently, every technician on our team is NATE-certified, has passed extensive background checks, and has undergone comprehensive training. We ensure our technicians do not earn commissions, focusing solely on your needs. We strive to be your reliable advisor for every plumbing and HVAC need.

Recommended Customer Reviews

I have used McLays Services on a number of occasions and have found them to be the best plumbing company around.
They have replaced my water softener, installed a tank less water heater, repaired a broken drain line under my living rooms concrete slab and on a few occasions cleared pipes that were slow.
Each time I called them they were professional and responsive. Arrival times were prompt and accurate. The quotes were competitive and inclusive of all itemized repairs. The company operates clean vehicles and use updated equipment, the techs are well trained and I can tell that McLays only hires the best and most knowledgeable people that they employ. Chad has been amazing with his knowledge and attention to detail. Truly a top notch organization that will not disappoint if you decide to utilize their services!

We had a major leak in a pipe leading to our kitchen sink. After doing the best I could to trouble shoot, I realized this was above my level of expertise. We called McClay and from the first moment they were professional and responsive. They set us up with a two hour window (10:00- 12:00) and arrived at about 10:05.
Roger was a great technician. Friendly, knowledgeable and professional. He diagnosed the issue, went to work and fixed our problem right away.
I would recommend these folks to family and friends in a heartbeat.
Thanks McClay and job well done Roger.

Excellent customer service, which is very important to me. There are companies that do not provide great customer service and they did! They also are very competitive in their prices. Overall, I highly recommend them.

First time using McLay and they did not disappoint. They had great reviews so I figured I could not go wrong. I called Maclay services due to water in smoke alarm. They came out the very same day and arrived as scheduled. Miguel was able to diagnose and repair my AC unit in a timely manner as well as explain the how the problem occurred. Will definitely call again for maintenance and repairs

Great response time and excellent service. I highly recommend this company for ac work.

I have found my to go to business with McLay! Our AC went out over the weekend and after much research I learned that not only does this business have good reviews on YELP, the next door app wrote recommendations for this business. Mike came out and explained everything and fixed our AC! I was happy with their services and reasonable prices! Thank you for your honesty and reasonable pricing.

My husband Tommy has known the owner Archie for 40 years. They went to high school together. Your never find a more honest, hard working guy than Archie. His work ethic shines through in his employee's. We had Chad out to fix our water heater. Chad does great work, he's also very knowledgeable. We are having him come back to do some work for our upcoming kitchen remodel. All and all we highly recommend Mclay's!!

I have known Archie McLay the owner professionally for over 20 years. He is very knowledgeable in his field, honest and trustworthy. Recently I had McLay Services replace the ducting of my HVAC system. The two men that did the work in my home did an excellent job. The air flow coming out of my vents has increased dramatically. I recommend McLay Services with no reservation. The only reason I gave 4 stars instead of 5 is because the technicians arrived approximately 1 hour late of the arrival window I was given.

We had a new water heater installed in our previous home maybe 15 years ago, and were very pleased.
We had a new water heater installed when we bought our current home 4 years ago, and again, excellent product and service.
Today they sent ""Scott"" to install an earthquake emergency gas shut-off device, and they continued their tradition of excellence and professionalism. What's better for a contractor than being on time, completing the work carefully and in a timely way, and representing your company with pride and class?
For a homeowner it's great to have a reliable plumber to call on, especially if an emergency arises.

We have used McLay for over 20 years and have had nothing but good service from them. They are honest, reasonably priced, and best of all they are excellent on making both proactive recommendations and repairs.
We have had problems occur while we were out of town, and McLay's stepped up and fixed everything while we were gone. They were more worried about getting the problem fixed than about getting their money.
We give them our highest recommendation and encourage everyone to give them a chance to show how great they are.
