We have the Gold Service Plan from MoreVent and it has been worth every penny. As a plan member you receive free regular maintenance for your HVAC system, which essentially makes the cost of the monthly plan a wash. Then on top of that you receive free service calls for any issues. They always get a technician to us the same day. They are courteous and clean up after themselves. In this case we needed a new circuit board, the plan covered repairs up to $1000, in this case it all came out to $1001 with tax and so a costly fix was completely covered by the plan. I would highly recommend MoreVent to any homeowner.
