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.

Yes, geothermal heat pumps are worth the money. You can save about 70% on heating costs in the winter and around 50% on cooling costs in the summer with a geothermal heat pump compared to a traditional HVAC system. Over time, your savings on monthly utilities will pay for the cost of the geothermal heat pump installation. If you have an incredibly small yard, however, you may not have enough space for this type of system.

There are three main types of heat pumps. An air-source heat pump system is the most common and has two parts—an indoor air handler unit and an outdoor heat pump unit. A ductless heat pump system functions similarly to an air-source heat pump system but doesn’t need ductwork to distribute the air. A geothermal heat pump system pulls heat from the ground to help heat your home.

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