Mark highlights that "lack of maintenance, pilot light issues, fuel supply problems, and electrical faults" are common reasons for furnace failures. He advises checking pilot lights, fuel supply, and electrical panels. If issues persist, consider the furnace's age and potential replacement. Newer models offer reliability and cost-efficiency, with installation costs ranging from $4,000 to $7,000.

Mark highlights that lack of maintenance often leads to furnace issues. For gas furnaces, check the pilot light; for electric, inspect fuses and breakers. Fuel supply issues can affect oil and gas furnaces. Mark advises, "Consider replacing old units for efficiency." Costs range from $4,000 to $7,000, influenced by size, efficiency, and location.

Mark advises, “Cover AC units in fall to prevent debris and salt damage.” He warns against full coverage due to critter risks. Use OEM covers or waterproof tarps. Perform maintenance in spring, including filter changes and clearing debris. Avoid using salt near the unit to prevent corrosion.
