It all started with a Groupon to check why our furnace wasn't blowing hot air and to perform a tune up on our lagging AC unit. It ended with the recommendation of replacing our entire 30 year old HVAC system. We didn't anticipate the full enchilada being necessary but it made sense to upgrade and get a fully functioning and much more efficient system. Carlos was extremely communicative and professional, as were his assistants. He worked with us on price and brand we desired, and even had his crew start at 6am on installation day to get the job done in a timely fashion and that worked better for our schedules. Talk about commitment to the customer! While we haven't had the chance to use the AC yet, we've been happy with the furnace during this recent "California cold snap". Thank you Carlos for your professionalism and workmanship. Will be recommending 5 Diamond to friends and will be back ourselves for our heating and cooling needs!
