We have 2 units in my home and the upstairs unit was not getting it done - we had 5 companies visit with us and while Griffin wasn't the cheapest, they were by far the most thorough and offered the most amazing guarantee on their product and the labor....UPDATE this work was performed June 2018 and we be happier, our utility bill has decreased dramatically and our home is more comfortable than ever. We recommend Griffin Service to everyone we know.
