"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!"

"Rafael came and was able to get our water heater pilot working quickly in a very professional manner. He the took extra time to go over its operation. There was no push to replace the heater which is eight years old, if I have more serious plumbing issues in the future, I will definitely call Diamond first."
