"Found me the right size water heater, a few days before Thanksgiving and had it installed within 2 hours. Clean and efficient and Bradford White gas water heaters are American made. Built to last. Daniel Westereng did a great job with the install. Clean, fast, thorough and polite."

"McLay Services did an excellent job on the preventative maintenance for my A/C system. Dylan was professional, courteous, and thorough throughout the visit. He replaced two air filters, cleaned the coils, and checked all electrical components to make sure everything was running safely and efficiently. My unit is now healthy and fully operational. I really appreciate the quality of work and attention to detail — I'd definitely recommend McLay Services to my friends and family!"

"Very nice and pleasant service guys came to install a new water heater and took the old one out. Very knowledgeable and helpful. People on the phone are really nice as well. These guys showed up a couple days before Christmas and was able to install the same day they came to inspect. They went out of their way to find the special size I needed so that I would not go without hot water during the holidays! I live in the mountains and there was snow and they had to crawl through a small opening to get the water heater out and put the new one in. I will definitely use these guys again for any future plumbing needs!"
