Phil at Custom climate tuned up my furnace and as always did an excellent job, in past visits he found and repaired poor work done by previous contractors. Have always appreciated Custom climate for all my HVAC work

Trevor from Custom Climates was on time, professional, and answered any questions I had about my older furnace. I definitely recommend giving them a call to schedule your annual maintenance - you won't be disappointed!

Maintenance for our AC - needed to check out a rattling and whirring sound. Called on a Saturday and they were here on Monday. Person was professional and was very thorough on checking the system out to correct the problem. He took the time to listen to us and had the issue resolved in a very short time. We have this company service our AC and heating system yearly. They have been great at all times. I would recommend them to my friends and family.
