Honest Air comes through for me again. Went downstairs last night to get some TP and found water around the base of our furnace. Called them after hours, they answered the phone and advised me on what to do. They were out here this AM and repaired the problem (which had nothing to do with the install they did last year) and fixed the problem and at a very reasonable price. Highly recommended Honest Air and a service contract with them.
