Is it possible to keep your house cool this summer without paying an arm and a leg to your utility company?

Absolutely it is. But it takes a little work on your part.

There’s nothing worse than feeling like you’re living in a pressure cooker, so we tend to crank up the AC when the weather gets hot outside. According to the U.S. Energy Information Administration, American households can expect to spend $422, or $141 per month, on electricity bills in June-August. In some parts of the country where summers get extremely hot, it’s common to see utility bills easily over a few hundred dollars per month.

So how can you keep your AC bill down this summer? There are some ways to save money on air conditioning, specifically helping your AC unit run more efficiently, which will help you save some summer cash. Follow these helpful ways to reduce your AC costs during the summer heat.

What Is Geothermal HVAC?

When it comes to environmentally friendly HVAC systems, geothermal heat pumps are a promising and increasingly popular option. Baby boomer customers are attracted to the energy savings geothermal HVAC systems offer. Millennials consider going geothermal because it’s better for the planet. In fact, geothermal is expected to supply 10 to 20 percent of the world’s energy by 2050. Geothermal HVAC and power systems use Earth temperature for heat exchange. While some areas of the country experiences extreme climates, temperatures underground remain constant.

Geothermal heat pumps are considered a form of high efficiency heat pump. These systems rely on heat transfers between the air and the ground to provide heating and cooling to homes and buildings. Two other forms of geothermal systems are direct use geothermal and deep and enhanced geothermal. Direct use geothermal systems are common in regions with volcanic or tectonic activity that results in naturally heated groundwater. In these systems, hot water is pumped to use in its current state or in heat exchangers to condition the air in the building.

Deep and enhanced geothermal systems are generally used to create electricity for large commercial, agricultural, and industrial applications. They rely on steam located far below the Earth’s surface that is accessed by drilling.

How Do Geothermal HVAC Systems Work?

Geothermal HVAC systems use the same science of refrigeration that other HVAC/R equipment relies on. Under the Second Law of Thermodynamics, heat naturally travels from hot or warm locations to cold ones. In a geothermal HVAC system, an electrically powered heat pump cycles fluid, usually water or refrigerant, through long loops of underground pipes. It is through this process that heat is transferred from ambient air in the building to the ground and vice versa.

During the winter, the heat pump sends fluid through the pipes where the warmer rock, soil, or water underground increases the temperature of the fluid. The warm fluid is then pumped back to the building. A heat exchanger can then transfer the heat from the fluid to the building’s heating system to warm the air. A desuperheater can be used to increase the temperature of water for use in the building. The process is then repeated, with the cooler fluid being pumped back into the ground to be warmed and then returned to the building for heating.

In the summer, the same process occurs, but this time the fluid absorbs heat in the air and disperses it into the ground. The cycle works to continually remove heat from the air in the building, thereby cooling it.

What Are the Advantages and Disadvantages of Geothermal?

Home and building owners will usually recoup the upfront cost of these systems through energy savings, as they can cut utility bills by 30 to 70 percent. Studies have shown that customers see a return on their investment in seven to eight years on average. Also, there is the benefit to the environment. The reduction in greenhouse gas emissions of installing a geothermal HVAC system is equivalent to removing two vehicles from the road or planting 750 trees.

Repairing Versus Replacing Your Old Air Conditioning Unit

When your air conditioning breaks down, the first thought that probably runs through your mind is: Will I be able to get it fixed, or will I have to purchase a new system?

It is usually less expensive to repair the unit than replace it. However, there are a few factors to consider before deciding whether to repair or replace. For example: the age of your air conditioning system. Remember that your air conditioning unit has an estimated service life of 10 to 15 years. Fixing an air conditioning unit that should otherwise be replaced, may just be a temporary solution and can cost you more money in the end.

Here are several factors to consider before making a decision: Continue reading
