Description of Work: I needed my water softener repaired

It went wonderful as usual. Chad is the wonderful and I can always count on McLay Services. They are just the best. I also use them for my heater and A/C and they are excellent and very fair. I highly recommend them.

Just had my home AC repaired by Alan. This guy is really good! He immediately identified the issue (burned out capacitor) and went back to his shop to get the part. Once fixed, he then checked out the entire systems health and noticed our filter was super filthy. He replaced my filter and checked temperature levels – ok! Thanks, Alan! I will definitely be calling you back when needed!

Showed up when they sar, diagnosed the problem quickly. As we have a heat pump we have had many issues with repairs, even with the company that installed it!
