Business ProfileforHetter Heating & Cooling Inc

I have an annual service contract with Hetter Heating & Cooling for the AC/Heating unit at my house 1*** ******** ** *****. Last July, I scheduled the summer service for the unit and the company rep came and conducted the service that including adding more cooling agent and thawing the pipes. The company sent me a bill for $717.27, which a thought was very high and included excessive charges. I called them to complain about the charges, indicating that the charges are too high and paid the full amount of $717.27 for the annual contract plus the charges. In mid-November, I called Hetter H&C to schedule the winter service for the heating unit, as the cold weather is getting worse. Their reservation secretary first told me that I have no contract for service, but after I gave the amount and date of payment she reluctantly agreed to schedule my house service for the last week of Jan 2022. I told her this date unreasonable and seems to me like a retaliation against me for complaining about your the high charges for the summer services. I asked her to schedule me for a more reasonable schedule and the week of January is too far in the cold weather for our house to remain without servicing the heating unit. I would like Hetter H&C company to re-schedule the service to our house for more reasonable and timely manner.
