Heating Oil questions, answered by experts

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.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

Geothermal systems provide energy efficiency, lower utility bills, and long-term sustainability with minimal environmental impact.

Your HVAC manufacturer will give you instructions on how often you should service your system. Have your unit professionally serviced at least once a year when in doubt. 

Heat pump systems are different because they provide heating and cooling solutions for your home. In this case, you should have it serviced at least twice a year.

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.
