Geothermal Maintenance Plan FAQs
How much does geothermal maintenance cost?
Our geothermal maintenance plans start at $90 per year for the Comfort Plan and go up to $215 per year for our most comprehensive coverage. Costs vary based on plan tier and number of units.
What’s included in a geothermal maintenance visit?
Each visit may include air filter replacement, system performance diagnostics, refrigerant checks, coil cleaning, thermostat calibration, fluid loop analysis, carbon monoxide testing, and more — depending on the plan selected.
Do I really need geothermal maintenance every year?
Yes. Even though geothermal systems are low-maintenance, they still require routine service to maintain peak efficiency, extend system life, and protect your investment. Regular service also helps detect small issues before they become expensive repairs.
How often are maintenance visits scheduled?
All Comfortworks maintenance plans include two service visits per year — one for heating season and one for cooling season. We’ll remind you when it’s time to schedule.
Can geothermal systems lose efficiency without maintenance?
Absolutely. Dust buildup, loop fluid issues, or incorrect refrigerant pressure can cause your system to consume more energy than necessary, raising your utility bills and reducing comfort.
Do maintenance plans include emergency service or repairs?
Plans include priority scheduling and discounts on diagnostic trips or unplanned service calls, but emergency repairs are billed separately unless otherwise noted.
Can I sign up for a Comfortworks service plan even if you didn’t install my system?
Yes! Comfortworks services all makes and models of geothermal and conventional HVAC systems — even if we didn’t install it.
What happens if I skip maintenance for a year?
Skipping maintenance may void manufacturer warranties and increase your risk of system failure. Just one missed visit can lead to avoidable wear on components and lower system performance.
What’s the best geothermal maintenance plan for older systems?
We recommend our Performance Plan or Works Plan for older or high-mileage systems. These provide deeper inspections and catch issues that may arise as the equipment ages.
Can I change plans later if my needs change?
Yes — you can upgrade or adjust your plan at any time. Our team will work with you to make sure you’re covered based on your system’s condition and your comfort goals.
Do geothermal maintenance plans save me money in the long run?
Yes. Preventative service reduces the risk of costly repairs, improves efficiency, and helps avoid emergency calls. Many homeowners see hundreds in energy savings annually when their system runs at peak performance.
