Nevada Residential Services are Awesome! I just bought an older home built in 1976 and right away knew I needed help with the HVAC system! There were no filters to be found and the furnace would run non stop. I call Nevada Residential Services and they responded immediately sending someone out to take a look. Vardan was our tech and he really knows his stuff!! He knew the system and let me know right away where the filters should go and got the unit running normal. As a new homeowner I really appreciated the time they took to explain my system and maintenance requirements. This business has excellent customer service, they were very professional, prompt and I will definitely add them to my home maintenance contact list. I have already passed on their business info to all my friends that own houses. Yes, they are that good!!
