How WaterFurnace Geothermal Systems Work

WaterFurnace geothermal systems provide efficient, all-in-one heating, cooling, and hot water by leveraging the earth’s constant underground temperature (around 55°F in Ohio). Here’s a simple breakdown:

A network of buried pipes, called a ground loop, circulates a water-based fluid that absorbs heat from the earth in winter (for heating your home) or releases excess heat into the ground in summer (for cooling). The geothermal heat pump inside your home transfers this energy to your forced air system, radiant floors, or hot water tank.

Compared to traditional furnaces or air conditioners, geothermal offers more even temperatures, quieter operation (no noisy outdoor units), and lower maintenance since the system isn’t exposed to outdoor elements. It’s perfect for residential applications in Northwest Ohio, where it can integrate with existing ductwork or radiant heating for whole-home comfort.

Key Features and Technologies

WaterFurnace leads the industry with innovative technologies designed for residential efficiency and comfort:

Variable and Dual-Capacity Compressors

Adjust output for precise temperature control, maximizing energy savings and minimizing wear.

OptiHeat Vapor Injection

Delivers high-temperature water (up to 150°F) for radiant floor heating or hot water, even in cold Ohio winters.

ENERGY STAR Certification

Questions About Our Service?

1. Will installing a geothermal ruin my lawn and landscaping?

The reality is, any disruption can often be restored by the dealer after the install, leaving no lasting impact on your yard.
In fact, some loop types greatly minimize the area affected.

Directional bore (horizontal) – The least impactful and disruption is negligible.
Vertical loop (closed or open) – Next best option for disruption. If your home has a well, you already have an open loop in place – saving not only disruption, but thousands of dollars!
Pond loop – A great option with disruption usually limited to a single trench line from the pond to the home.
Horizontal loop (trench) – The most invasive but also usually the lowest cost. Disruption can be repaired by reseeding.

2. Do you need a large yard for a geothermal installation?

If you have a lawn big enough to mow, you have enough space to implement geo thanks to new options for modest yards! Today, a traditional vertical loop can be installed in as little as 15×15 ft.

3. Will indoor geothermal units generate more noise than traditional HVAC systems?

Actually, WaterFurnace systems are among the quietest on the market.

Their units feature a fully insulated cabinet and advanced vibration isolation technology, allowing them to operate quietly, even at full capacity.

The WaterFurnace 7 Series takes it a step further with variable speed technology that precisely controls output and airflow making it THE quietest system that we have to offer.

4. Are geothermal systems more expensive to maintain?

Actually, WaterFurnace units need LESS maintenance than ordinary HVAC systems. That’s because they are situated inside the home (with loops buried safely beneath the ground), meaning they experience less exposure to the elements, far less wear, and last 40% longer than a traditional HVAC system.

And since there’s no combustion or open flames, you avoid the added risks and upkeep that come with fuel-burning equipment.

5. Are geothermal systems only for new homes?

While new builds are a natural fit, Waterfurnace offers a range of system configurations that make it easy to install geothermal in existing homes. In fact, many homeowners are surprised by how seamlessly geo can be integrated into older homes.

Geothermal systems can be installed in small yards with vertical loops as well as larger lots. They can also tie into most existing ductwork in your home and the equipment has a similar footprint in your basement as your current furnace.

6. What are the benefits of choosing a geothermal over traditional HVAC systems?

WaterFurnace offers up to 70% energy savings, quieter operation, better indoor air quality, and a smaller environmental footprint compared to conventional furnaces or air conditioners. They eliminate the need for outdoor units, reducing exposure to weather damage. For Northwest Ohio homeowners, this means reliable performance in extreme temperatures. M&M Heating and Cooling recommends WaterFurnace for its durability and efficiency, backed by our expert service.

7. How much does a Waterfurnace system installation cost?

Installation costs vary widely depending home size and installation type. Expect 5-10 year payback through lower utility bills, up to 70% savings on heating and cooling. At M&M, we provide free estimates and financing options through Wells Fargo to make it affordable for Northwest Ohio families.
