Wait, Do Geothermal Systems Work in the Summer Too?

Monday, August 5th, 2019

Why, yes! They do! But, we understand why you might’ve believed otherwise — c’mon, the word “thermal” is right there in the name!

Geothermal systems, like all heat pumps, come equipped with a reversing valve, which allows for both home heating and cooling. That way, you can enjoy year-round comfort with just the flip of a switch. But even still, geothermal systems are different than their forced-air counterparts, and many homeowners don’t quite understand how they work.

So below, we’ve decided to explain the science of it all. Just keep reading below to find out more! (And of course, remember to schedule your HVAC services in Andover, MN with our team!)

Do Geothermal Systems Require Frequent Repair?

Thursday, December 4th, 2014

There can be some concern in regard to repairing geothermal systems because of how the system is set up. As such, one of the main concerns is how frequently do geothermal systems need repair? The answer is: very infrequently. Not only are geothermal systems made to be durable, their operation is very different from more traditional systems, so the risk of malfunction is far less. Understanding how geothermal systems work helps explain why geothermal systems do not have the same frequency of breakdowns as other systems, so let’s take a look at how a geothermal system works.

Geothermal Operation

A geothermal system takes advantage of the steady temperature of the ground below the frost line to heat your home. It does this via a ground loop filled with a solution (typically anti-freeze) that absorbs the latent heat and transfers this heat to the ground-source heat pump. The heat pump concentrates the heat, then distributes it to your living spaces.

What About Repairs?

The ground loop is a simple component that does not have mechanical parts; in fact, the main mechanical component in a geothermal system is the heat pump. Furnaces and boilers are mechanical devices with moving parts, which makes them more prone to developing problems; a geothermal system does not have multiple moving parts. Additionally, unlike traditional combustion heating systems, geothermal systems do not generate heat; instead, they transfer heat. This, too, helps the system to be more stable. None of the geothermal components are exposed to the outdoors, which helps protect the parts from corrosion and damage. Lastly, the average lifespan of the equipment is some of the longest around: ground loops have an average lifespan of 25-50 years and the heat pumps have an average lifespan of 20-25 years.

Geothermal systems are the most energy efficient heating and cooling system available, so don’t let the possibility of geothermal repair in Lino Lakes keep you from considering a geothermal system for your home.

The Different Types of Geothermal Loop Systems

Tuesday, August 12th, 2014

Geothermal energy for home heating and cooling is a rapidly growing industry that is available to more homes now than ever before. One of the reasons that an increasing number of homeowners are opting for the geothermal heat pumps—aside from their advantages in reliability, longevity, and energy efficiency—is that the variety of different geothermal systems professionals can install means even more homes can take advantage of geothermal energy.

At Air Mechanical, Inc., we can handle installation of many types of geothermal loop systems in Oak Grove, MN. There are four basic systems available; contact our experience geothermal team to find out which type will work best for your home.

at Air Mechanical, Inc. our experts will survey your property to determine the geothermal installation that will deliver you all the benefits you expect.

The four different loop systems

  1. Horizontal loops: This is the most common type of loop system, and if a home has sufficient space and the right weather conditions, horizontal loops are usually the number one choice for geothermal installation. They are highly efficient and also easy to repair. The installers dig trenches 4–10 feet deep across the property, then lay the loops flat along the bottom of the trenches and fill them in.
  2. Vertical loops: When there is less space available for the loops, or when the loops need to be buried deeper to access a stable underground temperature, a vertical loop configuration may be the best option. The installers drill holes between 100 and 400 feet into the ground, and pipes connected with a U-joint are lowered into them, which are then joined to a horizontal pipe that runs to the heat pump.
  3. Pond or lake loops: Even though it goes against the name “geothermal,” water can also be used as a heat exchange medium for a geothermal system. If a home has a body of water close enough, the loops can be placed at least eight feet below the water surface to take advantage of the stable temperatures (and to avoid freezing during winter).
  4. Open loops: All the above systems are closed loop, which means they circulate an antifreeze refrigerant through them. With an open loop system, water is used as the refrigerant, and once it is used it returns to the ground. An open loop system connects to the fresh water supply to the house so it always has water available.

Which loop system will work best for my home?

To find this out, contact Air Mechanical, Inc. and arrange for an appointment. We will bring our years of experience to the task of determining which of the various geothermal loop systems in Oak Grove, MN will provide your home with year-round comfort and energy savings.

How Geothermal Cooling Systems Work

Friday, May 30th, 2014

Most people understand the basics of geothermal power: the planet Earth generates heat from its core, which then radiates outward toward the surface. Only about 10 feet below the ground, the Earth’s temperature starts to rise. Anyone who has gone into an underground cavern for any distance during cold weather will attest to the increase in temperature down below the surface. Systems that harness this heat are accessing a natural, clean, and renewable source of energy.

But how does this relate to cooling down a home? A geothermal heat pump can both warm up and cool down a home, and we’ll explain how this works.

To find out the necessary information to see if geothermal cooling in Andover, MN is appropriate for your household, call up the geothermal experts at Air Mechanical, Inc. today. Since 1985, we’ve cooled and heated the 7-county Metro Area.

The operation of a ground-source heat pump in cooling mode

A geothermal heat pump works much the same way that a standard air-source heat pump does: to cool your home, it removes heat from your indoor air and deposits it in the air outside. The process reverses for heating. The difference is that a ground-source heat pump (i.e. a geothermal heat pump) uses the ground for half of the exchange: it removes heat from the earth and moves it indoors for heating, and when you switch the system over to cooling, it removes the heat from indoors and puts it in the ground.

Because the temperature in the ground remains at a steady level that is hardly affected by the fluctuations of surface weather, the geothermal heat pump always has a heat supply for the exchange: at around 55°F, it works ideally to remove and deposit heat. The ground loops that carry out the exchange run water through them to move the heat from one place to the other, and without causing any damage to the soil. Ground-source heat pumps are both reliable and clean, with few emissions that might endanger the environment.

But will a geothermal heat pump work for my home?

That’s a good question. It isn’t one we can answer here: every house and property is different. Limitations on space and differences in the soil can make a geothermal system impractical in some locations. However, our specialists at Air Mechanical, Inc. will find the best way to either apply a geothermal configuration for what you have available, or suggest an alternative for heating and cooling that will bring you comfort and energy savings.

We are strong advocates of geothermal energy for homes, and we want you to take them into serious consideration.

At Air Mechanical we do our best to see that you have excellent geothermal cooling in Andover, MN if it is the finest option for your home.

Geothermal Tip: Saving Energy with Geothermal

Monday, January 7th, 2013

Keeping your home comfortable should be a top priority for any homeowner. The high costs of energy, though, can dissuade many people from keeping their homes as comfortable as they would like. With the installation of a geothermal heating and cooling system in Ham Lake you can greatly reduce the amount of energy you consume while still keeping your home effectively heated and cooled. If you would like to learn more about Ham Lake geothermal heating and air conditioning systems, contact Air Mechanical today. We have some information for you about how you can start saving energy with geothermal technology.

One important factor to keep in mind in order to maintain high efficiency heating and cooling output from your geothermal system is to know precisely where your geothermal loop system is installed. If you have any work done on your home you need to keep the digging away from this loop system. The geothermal loop system is responsible for drawing heat from the ground surrounding your property for use in your home. If this loop system is compromised or damaged your geothermal heating and cooling system will not operate efficiently.

You may also want to consider using your geothermal system to heat the water you need for showering and cleaning around the house. During operation in the cooling season your geothermal system will dump excess heat right back into the ground. You can use this heat to heat water that can be used in your home. Why pay for hot water service when you are just putting heat back into the ground anyway?

Be sure to fully understand the temperature controls of your geothermal heating and cooling system as well. A lot of inefficiency stems from simple human error. Get to know your thermostat or zone control systems in order to get the most out of these devices. This will allow you to use them, and your system as a whole, more efficiently.

If you have any questions about how you can get a more efficient performance out of your geothermal heating and cooling system in Ham Lake, call Air Mechanical. We have all the answers you need. Let us help you save money by reducing the amounts of energy you use.
