We offer 24 hour emergency service of equipment installed by us and to any current customers.  Unfortunately, we are unable to accept any new service customers at this time! 

EnergyStar recommends that you change your air filter regularly and we agree!


Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.

"Repaired the AC quickly on a very hot day. Mike responded to our request to fix our AC the same day we called. He was courteous, explained what he was doing and identified and fixed the problem promptly."


"we've had Card HVAC service our gas furnace two years running now and don't have plans to do business with anyone else for our heating & cooling needs!  They have prompt, courteous and thorough technicians who take the time to explain any concerns with our heating system.  Twice now we have had small parts keep the furnace from operating properly and they came out to get it up and running quickly.  Mike, his crew and Lori go out of their way to make sure to leave a positive impression on their customers and they are so pleasant all the time.
