AmeriServe did a great job repairing our nearly 20 year old oil furnace. Scott and Guy listened to my questions and concerns then thoroughly diagnosed the problems with the furnace. They did an oil tune-up and safety inspection, replaced the capacitor then came back the next day to replace the primary oil control and the wire for the thermostat. Our furnace now works fine. It's a relief to have piece of mind about our heating this winter! I highly recommend AmeriServe and would hire them again.
