Heating Oil questions, answered by experts

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

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

NATE-certified technicians may charge slightly higher service fees compared to non-certified technicians. This is because NATE certification signifies a higher level of expertise and professionalism, often leading to more efficient and effective HVAC repairs and installations. While the upfront cost may be marginally higher, NATE-certified technicians can potentially save you money in the long run by reducing energy consumption, preventing frequent breakdowns, and extending the life span of your HVAC system. When looking for a local HVAC company to hire, it never hurts to ask about NATE certifications.

A geothermal heat pump system will take about 10 years to pay for itself, and it has a life span of anywhere from about 25 to 50 years. Installing a geothermal heat pump will cost about $14,250 upfront, but it can reduce your energy bills by around 65% when compared to a conventional HVAC system.

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.
