Where Do Wells Go in a Geothermal System?
In a geothermal system, wells are drilled vertically or horizontally underground. Vertical wells go deep into the earth, while horizontal loops are buried in trenches. The location depends on your property size, soil conditions, and system design. FYI in New England 95% are vertical wells
We also have open loops where water is drawn from a large pond or lake. The drawback is that contaminates can enter the pipe and clog the system
How Does Geothermal Energy Work?
Geothermal systems use the stable temperature below the earth’s surface to heat and cool your home. A ground loop circulates fluid that absorbs or releases heat, which is then transferred indoors through a heat pump. Learn more here!
How Much Am I Going to Save Higher Efficiency Equipment A Month?
When considering upgrading to a more efficient HVAC system, one of the most common questions is how much you can save on your monthly bills. The answer depends on several factors, including the size of your home, the efficiency rating of the new system (such as SEER for cooling or AFUE and COP for heating), your current energy costs (which vary by location), and the insulation quality of your home.
Factors Influencing Savings
HVAC System Size and Efficiency
A higher SEER or AFUE rating means the system is more efficient. For example, upgrading from a 10 SEER to a 15 SEER can lead to significant annual savings on cooling costs.
Energy Costs
The cost of electricity, gas, or oil varies by region and can impact your savings. For instance, if you live in an area with high electricity costs, switching to a more efficient system can result in substantial savings.
Home Insulation
Well-insulated homes require less energy to heat and cool, maximizing the benefits of a more efficient HVAC system.
Local Climate
In regions with extreme temperatures, the savings can be more pronounced due to increased system usage.
Estimating Savings
To give a more precise estimate, you can use an HVAC energy savings calculator, which takes into account your current system’s efficiency, the new system’s efficiency, your location, and energy costs. These tools can provide a detailed breakdown of potential monthly savings based on your specific situation.
Real-Life Examples
- Upgrading from a traditional air conditioner with a SEER rating of 9 to one with a SEER rating of 13 can result in approximately 30% savings in energy costs.
- Installing a high-efficiency HVAC system can reduce utility bills by up to 20%, potentially saving over $1,000 annually.
What Is Better: Ductless Mini-Splits or Central Heat Pumps?
Ductless Mini-Splits offer several advantages:
Energy Efficiency
They avoid energy losses associated with ductwork, which can account for up to 30% of energy consumption in traditional systems. Mini-splits use inverter-driven compressors that adjust speed based on demand, providing high SEER ratings.
Flexibility and Zoning
Each room can be controlled independently, allowing for targeted heating and cooling only where needed.
Easy Installation
No ductwork is required, making them ideal for homes without existing ducts or for room additions.
Limited Cooling and Heating Capacity
Mini-splits may not be suitable for larger areas or very small areas and may require multiple units to achieve desired temperatures. This can increase costs and complexity.
Humidity Control
Mini-splits typically do not manage humidity levels well, which may require additional equipment like dehumidifiers or humidifiers.
Refrigerant Leak Issues
With multiple indoor units, identifying refrigerant leaks can be challenging and time-consuming.
Central Heat Pumps also have their benefits:
Whole-Home Coverage
They are well-suited for larger homes where consistent heating and cooling are needed throughout.
Cost-Effectiveness
While the initial cost of a heat pump might be lower, ductless systems can save more on utility bills over time due to their efficiency.
Environmental Benefits
Heat pumps can significantly reduce carbon emissions compared to traditional heating systems.
Year-Round Comfort
Central heat pumps provide both heating and cooling, making them versatile for year-round comfort. They can reverse operation to heat your home in winter and cool it in summer.
Ultimately, the choice between ductless mini-splits and central heat pumps depends on your specific needs, such as the size of your home, existing infrastructure, and personal preferences.
What is a heat pump?
A heat pump is an energy-efficient HVAC system that provides both heating and cooling for a home by transferring heat rather than generating it. It works by moving heat from one place to another, depending on the
How Does a Heat Pump Work?
Cooling Mode (Summer)
In warm weather, a heat pump acts like an air conditioner. It extracts heat from inside your home and releases it outdoors, leaving the indoor space cooler.
Heating Mode (Winter)
In cold weather, the process is reversed. The heat pump extracts heat from the outside air (even in cold temperatures) and transfers it indoors to warm your home.

What Are the Different Types of Heat Pumps?
Air-Source Heat Pumps
These are the most common type and transfer heat between your home and the outside air.
Geothermal (Ground-Source) Heat Pumps
These systems transfer heat between your home and the ground, using underground pipes to access the earth’s stable temperatures.
Water-Source Heat Pumps
These use a nearby water source, such as a lake or pond, for heat exchange.
What Are the Benefits of a Heat Pump?
Energy Efficiency
Heat pumps are highly efficient because they move heat rather than generating it, which can save money on energy bills compared to traditional heating systems.
Year-Round Comfort
They provide both heating and cooling in one system, eliminating the need for separate units.
Environmentally Friendly
By relying on electricity and avoiding fossil fuels, heat pumps reduce carbon emissions.
Versatility
Heat pumps can work in various climates, though their efficiency may decrease in extremely cold temperatures unless paired with supplemental heating.
When to Replace HVAC?
When homeowners ask if their HVAC unit is “good” and whether it will last, they’re often seeking reassurance about the system’s reliability and longevity–wondering when they may need to replace their system. Evaluating an HVAC unit involves considering several key factors, including the brand and model, installation quality, maintenance routine, usage patterns, and environmental conditions.
A well-known brand with a history of producing energy-efficient models tends to have a longer lifespan. Proper installation by certified professionals is crucial for optimal performance and longevity. Regular maintenance, such as changing filters and cleaning coils, is essential for extending the life of the system. The frequency and duration of HVAC usage, along with local climate conditions, also impact its lifespan.
A “good” HVAC unit is one that is well-maintained, properly installed, and suitable for your home’s needs, providing reliable service for many years. Regular maintenance and inspections can help identify potential issues early, ensuring the system operates efficiently and lasts longer.
How Can I Make My Older HVAC System More Efficient?
It’s extremely important to have regular maintenance on older HVAC units. Regular maintenance helps maintain the system’s efficiency, which can decline over time due to wear and tear. Cleaning filters, checking refrigerant levels, and ensuring proper airflow can prevent energy losses, keep your utility bills lower, and improve air quality. Overall, proper maintenance of your HVAC system will extend its lifespan so it can continue to keep you comfortable for years to come.

HVAC Facts & Common Misconceptions
Propane Costs the Same as Natural Gas
Many people struggle to understand how the type of fuel used in their HVAC system affects their monthly energy bills. For example, a 85% efficient unit will have different operating costs depending on whether it uses propane or natural gas or oil even though the efficiency is the same.
Fun Fact!
By installing energy-efficient windows, adding insulation, using spray foam in the sill plate, reducing air leakage, and strategically planting trees to block solar gain, homeowners can significantly reduce the size of the HVAC unit needed to cool their house. This results in substantial energy savings.
