Do you offer furnace service in South Portland, ME?
Yes. South Portland is part of our Cumberland County service area, and J&R Mechanical Services handles furnace service for homes throughout the area. Call (207) 902-8899 or book online to schedule.
How often should I change the furnace filter?
Every one to three months during heating season — monthly if you have pets or a dusty environment. A clogged filter is one of the most common causes of no-heat calls.
Is a heat pump better than a new furnace?
For many homes with ductwork, a ducted cold-climate heat pump can heat efficiently and adds air conditioning. Natural-gas customers often keep a furnace or pair one with a heat pump. We give you both options and the operating-cost comparison.
