Nelson (a McKinley technician) performed a furnace tune up and humidifier check-up and he found two major issues upon his inspection. I was also having some issues with my hot water heater and Nelson took a look at it as well. Nelson provided some options (along with pros and cons associated with each option) as to how to deal with all of these issues. I decided that replacing both the hot water tank and furnace were the best and most economical options. Nelson was honest and very thorough and neat when he performed the tune ups. Rhonda (Residential Sales Consultant) helped me to select the best furnace and hot water tank based on my needs and budget. Rhonda was also awesome in finding some carbon monoxide alarms for me as I did not have any and with my work schedule it was a bit difficult to go out to shop for them. Fredie and Melchor installed the new furnace and hot water tank and they did an excellent job. Fredie and Melchor arrived on time and worked steadily throughout the day. Not only did they have to replace the furnace, but they also had to reconfigure the furnace duct work so that it was up to code. These fellows were thorough, very organized and polite, a real pleasure to deal with. Everyone that I dealt with at McKinley's was excellent; they were helpful, patient, thorough and thoughtful and it was a real pleasure doing business with them. My experience with McKinley Heating, Air Conditioning and Plumbing was very positive and I would highly recommend them to anyone in need of their services!
