Heating Oil questions, answered by experts

You need to service an HVAC system about twice per year, with a service including an inspection and basic maintenance. It’s best to schedule maintenance in the spring (after the furnace has been running and before the AC kicks on) and in the fall (after the AC worked hard all summer and before winter’s first chill arrives).

Regular HVAC services will keep the system working as efficiently as possible, saving you money on utilities and larger repairs. HVAC maintenance costs around $250 per visit, while bigger repairs from forgotten upkeep could cost thousands.

Leaks, poor airflow, reduced efficiency, and loop blockages are common problems requiring service.

Service costs range from $200 to $1,500, depending on maintenance needs, system age, and labor.

Most maintenance checks take 2-5 hours, though extensive repairs may take longer.

For most systems, an annual HVAC system service is more than enough. Some homeowners prefer a twice-a-year visit to ensure the system is ready for the upcoming summer and winter seasons. If you need to call an HVAC pro more often than this, it may be time to check if your system is getting old enough for a replacement.
