FHP Geothermal Heat Pumps: Review & Models

FHP (Florida Heat Pump) is one of the oldest and most established manufacturers of geothermal heat pump systems in the United States. With over 50 years of experience in the heating and cooling industry, FHP has built a solid reputation among homeowners and contractors seeking reliable, efficient ground source heat pump solutions. If you're researching FHP geothermal systems for your home, this guide will help you understand their product lineup, efficiency ratings, and whether they're the right choice for your installation.

FHP Company History & Background

FHP was founded in the 1970s and has remained a privately held company dedicated to manufacturing heat pump equipment. The company specializes in both air-source and ground-source heat pump technology, with a particular focus on geothermal systems. FHP units are manufactured in the United States and sold through a network of licensed HVAC distributors and contractors across the country.

The brand is known for engineering equipment that performs well in extreme climates—particularly in Florida and the Southeast, where the company originated. However, FHP geothermal systems are installed nationwide and have earned respect for their durability and efficiency in residential applications.

FHP Geothermal Heat Pump Product Lines

FHP offers several geothermal heat pump models designed for different home sizes and installation types. Their product range includes both vertical ground loop and horizontal loop configurations, as well as options for closed-loop and open-loop (ground water) systems.

FHP's Main Geothermal Series

Ultra Series: FHP's premium geothermal line, designed for maximum efficiency and quiet operation. These units feature advanced refrigerant management and are suitable for both new construction and retrofits.
ClassicComfort Series: Mid-range geothermal models offering solid efficiency ratings and reliable performance for residential applications. These are popular with contractors installing standard ground loop systems.
Compact Series: Space-saving geothermal units for homes with limited indoor space for mechanical equipment. These maintain good efficiency while reducing footprint.

Efficiency Ratings & Performance

FHP geothermal systems are rated using two primary efficiency metrics: Coefficient of Performance (COP) and Heating Seasonal Performance Factor (HSPF). Modern FHP geothermal units typically achieve COPs between 3.5 and 4.5, meaning they deliver 3.5 to 4.5 units of heating or cooling for every unit of electricity consumed.

For heating applications, FHP's current geothermal models range from HSPF ratings of 7.5 to 10+, depending on the specific model and installation configuration. These ratings place FHP systems in the high-efficiency category, comparable to other leading geothermal manufacturers. Keep in mind that actual performance depends heavily on proper system design, loop installation, and maintenance.

FHP geothermal equipment qualifies for the federal tax credit, which currently allows homeowners to claim 30% of the total system cost (including installation) on their federal taxes. Check the federal tax credit calculator to estimate your potential savings.

FHP Geothermal System Costs

The total cost of an FHP geothermal system installation typically ranges from $25,000 to $45,000 for a residential home, depending on your location, home size, and ground loop type. The equipment itself (the heat pump unit) usually represents 30-40% of the total project cost, with the remaining expense going to drilling, piping, labor, and design work.

Cons of FHP Geothermal Systems

Not the most cutting-edge: While reliable, FHP doesn't always lead the market in the newest efficiency innovations compared to some competitors.
Limited marketing: Less consumer brand recognition than some larger HVAC manufacturers.
Parts availability: Availability may vary by region; best availability in the Southeast where the company is based.
High upfront cost: Like all geothermal systems, total installation cost is significant, though long-term savings typically offset this.

FHP vs. Other Geothermal Brands

FHP competes with major manufacturers like Carrier, Trane, Lenox, and WaterFurnace in the geothermal market. While all these brands offer high-efficiency systems, FHP's strength lies in its specialized focus on geothermal technology and strong contractor relationships. Performance differences between top brands are usually minimal when systems are properly installed and maintained.

Installation & Maintenance

FHP geothermal systems require installation by certified HVAC contractors experienced in ground source heat pump work. To find qualified installers in your area, use our find a geothermal contractor tool. We recommend working with IGSHPA certified contractors, who have demonstrated expertise in geothermal system design and installation.
