Residential Geothermal Heating and Cooling Earth River Geothermal Maryland

he economic benefit of harnessing geothermal energy is clear. A ground source geothermal heat pump is the most energy efficient heating and cooling technology available and it can cut your energy bills in half. Learn more about geothermal heating and cooling costs versus conventional HVAC systems.

Under current federal law there is a 30% federal geothermal tax credit for residential geothermal installations with no upper limit. The State of Maryland provides Maryland geothermal heat pump grants of up to $3,000 for residential geothermal heat pumps and up to $7,000 for commercial geothermal systems. What’s more, there are new local incentives such as Anne Arundel County’s geothermal property tax credit of up to $2,500. When these geothermal energy tax credits and grants are coupled with the most energy efficient heating and cooling system on the market, your renewable energy investment can pay dividends with a payback period of as little as 5 years, depending on the type of HVAC system being replaced.

Geothermal Heating and Air Conditioning in Maryland

Read this great article about Geothermal Heating and Cooling in Maryland. It also chronicles Earth River Geothermal’s installation of the Martin family’s geothermal HVAC system in Annapolis, Maryland.

Why should I choose a geothermal heat pump system in Maryland?

  • The subterranean geothermal temperature in Maryland is a steady 57° Fahrenheit, 365 days per year. This baseline temperature is ideal for both geothermal heating and geothermal cooling.
  • Geothermal pumps return up to $5 worth of heat for every $1 spent on electricity.

Why should I make the switch to geothermal sooner than later?

  • Energy prices are rising and heating and cooling costs account for up to two-thirds of a household’s energy bill; geothermal systems can help cut your energy bill in half.
  • Generous federal, state and local geothermal tax credits and grants enacted under the American Recovery and Reinvestment Act of 2009 are set to expire in 2016.

Geothermal Heat Pump Lifespan

Geothermal systems can have a payback period of as little as 5 years. On average, modern geothermal heating and cooling systems have a lifespan of 24 years. Furthermore, geothermal ground loop piping is warranted by the manufacturer for 50 years and is essentially an energy legacy for the property. The efficiency of the equipment installed by Earth River Geothermal is certified under the Environmental Protection Agency and the Department of Energy’s Energy Star® program. With a long system life and less maintenance, overall life cycle costs are much lower with geothermal systems.

Geothermal System Benefits

Lower Operating Cost – Seventy-five percent of the energy produced by geothermal systems comes from the ground beneath your property, which has a stable temperature of 57° Fahrenheit. Taking full advantage of this clean energy source makes sense. The cost of a geothermal heating and cooling system is generally recovered in energy savings within a few years. Enhanced Comfort – Geothermal Systems deliver consistent temperatures that are much warmer in the winter than conventional air-source heat pumps. When cooling, a geothermal unit delivers cool, dehumidified air. Quiet – Unlike ordinary air conditioners and heat pumps, there is no noisy outdoor unit. Geothermal heat pumps are designed for quiet operation similar to your refrigerator.

“I thought Earth River Geothermal did an excellent job! We had a vertical heat pump put in by them replaces a two heat pump system in our house. They were professional and efficient in getting the job done, and everything has been working great. They also were very helpful in getting all the paper work done for the grants/tax rebates.”
Jenny Z.
“BOTTOM LINE: Very Happy! Its been 1 year since my Earth River Geothermal system was install and replaced my 45 year old oil furnace and my 11 year old heat pump with a clean, quiet, energy efficient geothermal system. My total cost for the system after more then $10,000 in fed, state, county rebates was about $13,000. My fuel oil alone was costing $3,000 annually (based on 2012 pricing). My annual electric bill actually decreased. I no longer have a 275 gallon fuel oil tank in my basement and the associated odor, noise and carbon monoxide hazard from burning oil. Also gone is the noisy outside heat pump unit. What’s not to like!”
“I engaged Mark Schultz and his team to install a Geothermal HVAC system in my home in Annapolis. The process from start to finish was made easy by their level of expertise. I had, two years earlier, done the same, in a home in Rehoboth Beach using a different company and although that system works great the process and follow up needed was painful. Not with Mark and the folks at Earth River, first class owner and team who do first class work. The savings are what was projected and help with the paperwork to get the rebates was appreciated. Money well spent.”
James A.
“Earth River Geothermal with Bair Necessities and Winslow Well drilling did a great job … I highly recommend Mark Schultz.”
Ed J.
“Installing a Geothermal system from Earth River Geothermal was one of the best decisions I ever made. Being an Engineer myself, I really appreciated Mark Schultz’s knowledge on everything. If you want someone who will spec out a system to fit your needs exactly, Mark is the one. Combined with the installation by Bair Necessities, the system came together flawlessly. We have had our system for about 3 years now, and have saved 70% on our heating and cooling costs, which works out to $2,000 saved each year. Geothermal is a great investment, and I HIGHLY recommend Mark Schultz and Earth River Geothermal and the contractors that he uses.”
Craig C.
“Mark Schultz and team (Bair/Winslow) installed our geothermal system in July 2010 replacing the original (1978) oil furnace. All of the folks involved were very conscientious and easy to work with. I can’t say enough about Mark’s patience as I asked an awful lot of questions given the size of the investment. The various tax credits made it an easy decision financially. The green nature of the project is all icing on the cake! Our unit has performed flawlessly and we are very pleased with the ongoing cost. In Maryland, I think the bigger savings comes from the summer when we have a much more comfortable house at half the old cost for AC.”
Skip N.
“I could not be happier with the entire process of having a Geothermal HVAC system installed in my home, replacing my oil furnace. The idea of geothermal was intriguing to me; Mark Schultz was very helpful in answering my many questions. Earth River geothermal worked seamlessly with Bair necessities and Winslow well and pump, planning and installing the system, from permits to operation, as well as walking me through the paperwork necessary to obtain the over $10,000 in rebates from B.G.E., AA County, Md, and the Feds. Geothermal is the way to go, and I highly recommend Mark Schultz and Earth River Geothermal.”
William L.
“We are delighted with the new system. The house is more comfortable than ever before, and the system is completely unobtrusive. It’s so quiet I can’t tell when the blower is on.”
J. Carley
“We’ve been very pleased over the last few days with the system. Between the geothermal and zoning, our house has never been more comfortable.”
B. Wuerdemann
“Great service and good quality. Mark initially spoke as knowledgeable of both the mechanics and the geology that this type of job [entails]. He also stepped up immediately to tackle concerns that I had and was very responsive. [The geothermal heating and cooling system] performed as expected saving a fair amount of money on electricity while increasing overall comfort.”
R. B.
“Our energy costs are about 1/3 less … We are keeping the house several degrees warmer this winter than before, and the temperature during winter months has averaged a couple of degrees colder. So the comparison is even better!”
H. G.
“We think ERG is superb… Our energy costs are lower after the retrofit. We would recommend Earth River Geothermal to a neighbor or friend any time it comes up. Plus we’ll take reference calls from your prospects. It’s not a big deal if they come out of the blue; just send me a quick email [before they call].”
K. Avery
“We are very happy, satisfied and pleased with our system, the service and the company Earth River. I have already spoken to several of your potential customers and would be happy to continue doing that for you…We are very happy for your help in getting us a better grant from MES than we were originally told we would get. Mark is great about communication on all these things. Thanks again!”
D. S.
“Mark has been great at responding to all my questions; that, and the ability to have one contract, sold me on Earth River.”
B. D.
“Geothermal heating is a ‘no brainer’… We can continue to enjoy the house, be more energy efficient, and have a greener planet. We’re trying to make a little bit of [a] difference.”Your Content Goes Here
J. M.
“We were pleased with the year to year comparison this first [full post-install] month. Even after accounting for a three degree higher than average temperature. 11 therms versus 134 therms is rather compelling. Our bill was $263 lower despite what I’d imagine are equal or higher per-therm prices year over year… The incalculable soft benefit was that this year we maintained a comfortable 70°F whereas last year we did the typical thermostat gymnastics and would allow it to get a bit chilly at times. Pun definitely intended, we’re rubbing our hands together anticipating a cold month’s savings!”
D. P.
“We decided to use Earth River because of Mark: his integrity, other values and technical smarts. His responsiveness to my multitude of technical questions.. plus, his pricing beat the pants off of [the competition].”
B. D.
“All has been good. I would be happy to serve as a reference.”
