Heating Oil questions, answered by experts

If a geothermal heat pump is installed correctly, then you shouldn’t have to worry about having a backup heat source such as a furnace or oil boiler. However, there are geothermal systems installed that include a backup in case the heat pump fails due to extreme cold. This is simply a backup heat pump you’ll likely never need and not an alternative heat source.

The most obvious downside is the high upfront cost of buying and installing one of these systems. Additionally, sometimes the system can take a longer time to heat than alternatives like a boiler. Also, if something goes wrong with the geothermal pump, repairs are often significantly more expensive than repairing traditional, above-ground heat pumps.

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.

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.

Yes, technicians check refrigerant levels, loop performance, and system calibration for peak efficiency.
