Geothermal HVAC Services in Granbury, TX
Most homeowners don’t think about geothermal heating and cooling until their energy bills get bad enough to start asking whether there’s a better option. There is, and the technology has been around longer than most people realize.
Daffan Cooling & Heating installs, maintains, and repairs geothermal systems in Granbury, Weatherford, Stephenville, and throughout Hood County. This page covers how the system works, what it typically costs, and how to know whether your property is a good candidate.

Why Granbury Homeowners Switch to Geothermal
Running central AC from May through September in Granbury adds up. If your system is aging, inefficient, or constantly needs service, geothermal is worth understanding before your next major replacement.
- Lower energy bills: Geothermal systems typically cut heating and cooling costs by 40 to 60 percent compared to conventional HVAC, because the ground temperature is far more stable than the air.
- More consistent temperatures: Conventional systems cycle on and off and can leave rooms at varying temperatures. Geothermal maintains much more even conditions throughout the home.
- Quiet operation: There’s no outdoor condenser unit running in your yard all summer. The main components are underground and inside the home.
- Long equipment life: The indoor heat pump unit typically lasts 20 to 25 years. The ground loop, properly installed, can last 50 years or more.
- Lower long-term maintenance: Fewer components exposed to the elements means less wear over time.

Our Geothermal HVAC Services in Granbury:
Geothermal Installation
Full-service installation from site evaluation through system commissioning. We handle the ground loop design, indoor equipment selection and installation, and connection to your existing ductwork.
Geothermal Repair
If an existing geothermal system isn’t holding temperature, is short-cycling, or is consuming more energy than it should, we diagnose the actual cause rather than guessing. Problems can originate in the heat pump, the ground loop, or the controls, and we have the training to distinguish between them.
Geothermal Maintenance
Annual maintenance keeps the heat exchanger clean, confirms refrigerant levels and flow rates, and catches developing issues early. The ground loop requires very little attention once it’s installed, but the indoor equipment benefits from regular service like any mechanical system. Ask us about available maintenance plan options.
Geothermal vs. Air-Source Heat Pumps
Air-source heat pumps have become more common in recent years and are worth understanding in comparison. Both are heat pumps, but they work against very different conditions.
An air-source heat pump exchanges heat with outdoor air. When temperatures hit triple digits in August, the system is trying to dump your home’s heat into air that’s already extremely hot. Efficiency drops significantly under those conditions.
A geothermal system exchanges heat with the ground, which in the Granbury area stays in the 60s regardless of what’s happening above the surface. On the hottest days of summer, the system has a much easier job. That stable ground temperature is the core of geothermal’s efficiency advantage.
Is Geothermal a Good Fit for Your Granbury Home?
Geothermal works well in North Texas, but a few things determine whether a given property is a good candidate:
- Lot size and layout: Horizontal loops are buried in trenches and need more surface area, roughly half an acre of clear yard for a typical home. Vertical loops go several hundred feet straight down and require less surface area. Both approaches work in Hood County.
- Soil conditions: The clay-heavy soils common in this area transfer heat reasonably well, which actually favors geothermal performance here.
- Home size and existing ductwork: Most homes in the 1,500 to 3,000 square foot range need a 3 to 5 ton system. Geothermal heat pumps work with standard forced-air ductwork, so most existing homes don’t require major modifications.
- Your timeline: The upfront cost is higher than a conventional system. The longer you plan to stay in your home, the more the operating savings offset that difference.
Don’t Let the Timing Hold You Back
A new system is a significant expense, and it doesn’t always line up with a convenient moment in your budget. We offer financing through First Financial Bank with a simple application and fast credit decisions, so you’re not stuck waiting to get your home back to comfortable.

What a Geothermal Project Looks Like
For homeowners who haven’t been through this process before, here’s what to expect:
- Site evaluation: We assess your property first. Soil conditions, lot size, and your home’s actual heating and cooling load all feed into the system design. An improperly sized ground loop will underperform regardless of equipment quality.
- System design: Based on the evaluation, we determine the right loop configuration and size the heat pump to match your home’s needs.
- Installation: This involves excavation or drilling on your property depending on the loop type. We’ll walk you through exactly what to expect for your specific site before any work begins.
- Commissioning: Once everything is connected, we run the system through a full performance check to confirm it’s operating correctly before we consider the job complete.

Geothermal HVAC FAQ’s
Is geothermal actually proven technology?
Yes. Ground-source heat pumps have been used in residential and commercial applications for decades. They’re well-understood systems installed in hundreds of thousands of homes across the country, including many in Texas.
How long does a geothermal system last?
The indoor heat pump unit typically lasts 20 to 25 years, which is considerably longer than most conventional HVAC equipment. The ground loop, when properly installed, can last 50 years or more.
How often does a geothermal system need to be serviced?
Annual maintenance is the standard recommendation, similar to any heat pump. The ground loop itself requires very little attention once it’s in the ground.
Will installation tear up my yard?
There will be some disruption depending on whether your site calls for horizontal trenching or vertical drilling. We’ll explain exactly what to expect before any work starts, so there are no surprises.
Does geothermal work in Texas heat?
It actually performs particularly well in hot climates. Because the ground stays cool relative to summer air temperatures, the system works against a much smaller temperature difference than a conventional AC. Granbury summers are precisely where the efficiency advantage shows up most clearly.
What does a geothermal project cost?
Upfront costs are higher than a conventional system, but operating savings over time typically make the investment worthwhile for homeowners planning to stay in their home for ten or more years. We provide free estimates and can walk you through financing options during your consultation.
Can geothermal help with hot water costs?
Many geothermal systems can be configured to assist with domestic hot water as a secondary function. It doesn’t fully replace your water heater, but it can offset a meaningful portion of those costs over the course of a year.
Curious Whether Geothermal Makes Sense for Your Home?
The best way to find out is a site evaluation and a straightforward conversation. There’s no pressure and no obligation. Daffan will look at your property, run the numbers, and give you an honest answer on whether it’s a good fit.
