With the escalating price of natural gas and other fuels, geothermal heating and cooling has become an increasingly popular alternative for residential and commercial applications. Where conventional methods burn fossil fuels to create heat, the geothermal process simply harnesses the existing energy of the earth. A mixture of water and non-toxic antifreeze is constantly circulated through a closed loop of pipe buried in the ground in vertical or horizontal bore holes. In winter, the earth’s heat is absorbed by the circulating liquid. Ground source heat pumps transfer this heat to the building; in summer, the process is reversed, thereby dissipating the heat from inside the building into the ground.
Bertram Drilling Corp., and it’s sister company, Bertram Drilling Inc., of Billings, Montana, have been involved in the drilling of bore holes and installation of closed loops and geothermal equipment for many years.
- Efficient, cost effective
- Quick recovery of initial investment
Lowering your monthly utility bills has never been easier with Bosch’s Energy Star rated geothermal heat pumps. A Geothermal Heat pump use the relatively constant temperature of the earth to provide heating, air conditioning and hot water.
Kent Penning is a Renaissance man who loves what he does—helping to multiply an increasing number of satisfied customers from the work of Cold Craft, his company in the southwestern San Francisco Bay Area, established in 1991. Aside from enhancing Cold Craft’s reach, his interests range from martial arts to motorcycling, to teaching HVAC for San Jose City College, and enjoying fine wines. Always striving to learn about business operations himself, Kent is active in a local entrepreneurs organization. (Motorcycles and fine wines?) Like we said, a Renaissance man!
NATE Diamond-Certified status since 2002 has been maintained by Kent, and every technician at the company. The company carries California contractor licenses C20, C38, B, and C36. There is nothing in HVAC mechanical that Cold Craft can’t handle, and they are proud to be specialists in geothermal heat pump applications. Kent came up from the field as an HVAC technician before starting his company, and CaliforniaGeo is pleased to have Cold Craft as a member.

Martin Energetics is the dba of a consultancy that first operated as a residential design and solar thermal sales and installation effort in the early 1980s that included contract training for residential energy auditors and Title-24 workshops for California SMACNA. Its Principal was a full-time college instructor at the time and his remote location in the northern Sierra Nevada did not support this side business.
When Bill’s retirement from 35 years of teaching came in 2006 and plans for his “last house” were being finalized with geothermal in mind, the Martin Energetics moniker was revived. Within a three year period, a frenzy of activity ensued. Bill designed and built that house as the general contractor and electrician, and designed the geothermal system it carries today. He also was project coordinator on a 7-ton, two heat pump system in the same community. He went to Stillwater, Oklahoma for his installer certification, joined CaliforniaGeo, and became emphatic about carbonless Zero Net Energy.
His all-electric home completed its first year as a solar NEM customer of PG&E in November, 2015 and demonstrated Zero Net Energy positive performance by exporting 1,500 Kwh more to the utility than was used. Bill serves as CaliforniaGeo’s President.

Precision Directional Boring specializes in Horizontal Directional Drilling. This is a trenchless method of placing utility lines without the need to disturb much of the existing surface.
At Precision Directional Boring we do it all Safe, Fast and Neat. Our team of professionals works with existing utilities and the knowledge of underground structures to place your utility needs without costly down time or major surface restoration. We have all the latest technology and state of the art equipment. Our highly trained personnel can get your job done at a competitive cost and in a timely fashion. Our services are scalable so no matter what type or size project you have, we can handle a particular component of the project or if you like, we can turnkey the entire project for you.
Precision Directional Boring offers complete turnkey underground construction solutions for its customers. Precision Directional Boring also offers additional services such as build trench/bore logs, red-lined prints and on-going infield evaluations and suggestions.
DRY & WET UTILITIES: Precision Directional Boring, Inc. provides horizontal directional drilling services to steer over, under, or around buried utilities. We can curve the bore path to go around buildings or even drill under buildings if necessary. The electronics inside our drilling tools allow our operators to locate the drillhead with precision, ensuring that utilities already in place are not damaged.
When the drill has navigated past the obstructions and exited at the desired spot, we can pull back the conduits you need. These conduits can be used for gas, electric, telecommunications, or virtually any other use. We can pull back almost any material you need.
REMEDIATION WELLS: A horizontal soil vapor extraction system has a longer interval of screen in contact with the contaminated zone and provides a greater recovery in the vertical dimension, creating a much greater zone of influence than typically can be achieved with vertical wells. Horizontally drilled extraction wells are therefore more efficient and are also less likely to short-circuit to the atmosphere than those installed by trenching, since the soil column is not disturbed during the installation process.
In a horizontal system, the line acts as both the recovery and the conveyance lines. The same pipe provides both the screened section to extract vapors and a blank section to carry the vapors back to the surface. A single pipe can thereby replace both a series of vertical wells and the near-surface trenched conveyance lines required to transport the extracted vapor to the treatment system. We have installed these horizontal soil vapor extraction systems at dozens of sites where there was no disruption of normal site activities.
ROCK DRILLING: Precision Directional Boring uses Ditchwitchs’ All Terrain technology drill & steer in the rockiest of conditions. This system can steer, drill and backream in just about any type of soil—even solid rock—up to 1600 feet.
ON-GRADE SEWER: Precision Directional Boring utilizes AT technology along with a laser guidance system to achieve on-grade pipeline installation that can accurately install to within 1% of fall.
VACUUM EXCAVATION: Vacuum excavation is the latest technology using kinetic energy in a high velocity air stream to penetrate, expand, and break up soil. When compared to water or other excavation methods, air accomplishes difficult excavating tasks with speed and efficiency. The result is increased production and reduced cost. In addition, there are added safety benefits for both the operator and utilities. Vacuum excavation is the clear choice for safe and efficient locating of underground utilities.
TRENCHING: Our experience ranges from mass excavations and deep trenching in complex urban environments to long-haul trenching projects in rural communities.
