Heating Oil questions, answered by experts

Costs depend on system age, type, labor, and whether part replacements are necessary.

DIY maintenance like filter cleaning is possible, but professional servicing ensures proper pressure, refrigerant levels, and loop performance.

Yes, many providers offer organic or eco-friendly treatments. Confirm availability with your contractor.

You can expect a geothermal system to last for years. According to the Department of Energy, the underground infrastructure for the heat pumps lasts about 25 to 50 years, which includes the pipes buried in the soil. The actual heat pump itself has a life span of around 25 years.

Most HVAC companies charge a flat service call fee of between $75 and $150, which includes traveling to your home and inspecting your system to find the underlying problem. Keep in mind that these prices only include diagnostics and the actual repairs will usually be billed separately. If you’re calling for routine service, the service call will be included in your inspection and tune-up, with the total sitting around $150. Your prices could be a little higher if you have a very large home with multiple condensers and air handlers, as inspections and servicing take longer.
