S. Martin in Waterloo

Delta staff and trades people were very professional. Ryan inspected our furnace and suggested we have the furnace coil cleaned while he was already at our home. This avoided the extra cost of a second service call. On the morning the furnace was installed Rachel (Delta Customer Service) called ahead of her arrival to ask if we wanted a coffee. She arrived a few minutes later with coffee for furnace installers Shawn and Brian. Shawn and Brian explained every step of their work, they worked clean and quietly. Everyone involved phoned before arriving at our home. Everything was in writing, estimates adhered to, they handled all paperwork, and repaired the wall where the old thermostat was removed. Rachel returned to our home the following week for a follow-up to see if we had any questions about the work Delta had completed. My husband and I are pleased to recommend Delta Air Systems very highly.
