I need a recommendation for a heating/cooling company. Right now for cooling. A company or person that doesn't charge a service fee to "fix" the problem (that isn't really the problem) then charge another service fee to "fix" the problem...repeat repeat. Or is that how it works with heating/cooling? We replaced an entire unit last year after multiple service fees of "fixing" things only to have it not working again this year. Just looking to find someone to stand by their work. Thanks.
