We purchased a new furnace from Service Experts (formerly Knochelmann's Service Experts). It took over two years for it to be inspected and pass.
The drain hose leaked water into the room and damaged our property. They are self-insured and the third party adjuster refuses to pay us a reasonable amount for the damage done to our property. He suggested we claim it against our home owner's policy.
This company has cost us a lot more money than just what we paid for a new furnace. They have been a headache and we sincerely regret getting involved with Service Experts.
