"Came right on time. Installers were friendly and professional."

"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!"

"After recovering from a horrendous experience with Service Champions (NEVER EVER call them), I got several other quotes to completely replace my old AC system. Brandon and HD had the most competitive quote, great reviews and were very personable and professional. They installed entire new system and did a great job in a timely manner. I highly recommend!"

"I Called to get an in person quote for a tankless water heater flush and left this job with a whole house filter and a fridge connection. When Michael first arrived we inspected the tankless unit and tested the water to conclude flushing was not my best option. He then walked me through my options for home filters and we decided on a Halo system. Michael was very well educated on the subject and gave me the best value filter for my needs. He installed the unit the next day in less than a few hours and left me with a flawless work of art. I couldn't be more impressed with the professionalism he brings to this trade! I also requested to hook up a fridge and he did that in what seemed like 30 minutes. He will be the only plumber I call from now on!! Thank you Michael!!!"

"Installation went smoothly with great clean-up and follow-through. He had the metal shop make a protective cover for the air scrubber as it is mounted on the outside of the HVAC unit."

"Initially I considered having to pay $8000-ish for a replacement unit. Robert Alfonso saved the day, however. Well trained by LA Tech, and professional from start to finish, Robert diagnosed and resolved my wiring and capacitor issue quickly. The fix was $485 not $8000 to replace the unit. These guys are legit. Great result. Robert "Doctor" Alfonso rocked it."

"Technician checked ducts for leaks and water condensation tray and compressor and coolant levels and more. All was good except he found a relay that was all corroded and suggested replacement, which I did. I feel that I'm in good hands and they know what they are doing and I will use them again."

"Very happy with their installation of a solar attic fan. Also work was completed in less then estimated time."

"My A/C unit quit cooling after 16 years of flawless performance, I received quotes on the replacement and I chose RKM for their excellent reviews, the pricing they offered and the warranties. They scheduled the replacement in less than a week and completed their work in one day. Everyone I dealt with from the initial assessment to the installation crew were friendly, knowledgeable and respectful of our house. There was no sales pressure and all my questions were answered to my satisfaction. Matthew and Jason provided the utmost customer service as well as the other crew members. RKM exceeded my expectations."
