Customer Reviews from the Castle Rock Area:


“BEN was fantastic. Very knowledgeable and explained every step of the process in complete detail. Within 5 mins of a seeing the unit he knew exactly what the problem was and how to fix it. Ben listened to our concerns and gave us better options for optimal performance of our system and also recommendations for this problem . Eliminating reoccurrence and the appropriate maintenance schedule recommended for our unit. With his wealth of knowledge and approach NOW is very lucky to have BEN on their team.”

– Louella N. – Castle Rock, CO

“Very kind people both at the office and in the field. They were able to accommodate our dryer vent emergency (major blockage, exhaust backing up into the laundry room — thanks previous homeowner) within the hour, and their price is quite reasonable, no gouging or high-pressure sales tactics. Will definitely be using them again!”

– Eva C. – Castle Rock, CO


“This is the second time we have used Now Heating and Air. We needed our AC looked at because it stopped cooling. Fast response and the office sent Zack out to do a check. Zack did a great job, but it turned out we needed a whole new unit. WE picked a Lennox system. The tech showed up on time and surprise surprise it was Johnny. He installed our unit 18 years ago. Well, of course everything went great. His helper, Eddie was great. Thanks guys!!”
