Geothermal Design & Installation
from Buchanan & Hall
The Smartest Way to Heat & Cool
Geothermal systems — also known as ground source heat pumps — heat and cool your home or building by using the stable temperature underground. Unlike traditional HVAC systems that burn fuel, geothermal systems transfer heat to and from the earth, making them one of the most energy-efficient and reliable ways to stay comfortable all year. Whether you’ve heard it called geo heating and cooling, geo-thermal heating and cooling, or even an underground heating and cooling system, it’s the same smart, sustainable solution.
At Buchanan & Hall, we design and install custom geothermal heating and cooling systems for homes, farms, and businesses across Ontario. If you’re looking for a geothermal heating and cooling contractor near you, look no further. Our expert team has over 40 years of experience delivering systems that are built to last.

Types of Geothermal Ground Loops

Horizontal Trench Loops
- Land size dependant based on design
- Trenches range from 100 – 300 ft long
- Polyethylene pipes inserted into trench (approx. depth 5 ft)
- Trenches dug & backfilled using excavator
- Typical home requires ¼ to ¾ of an acre for trenches

Directionally Drilled (Horizontal Bore) Loops
- Land size dependant
- Ground Loop can avoid disrupting surface & subsurface obstructions on site
- Double pipe connected by U-bend inserted inside horizontally bored holes
- Depth of holes dependant on soil conditions & system size
- Digging only required for header trench where pipes join
- B&H is the only contractor in Ontario with their own directional drilling equipment

Vertically Drilled Loops
- Useful where space is limited
- Requires drilling rig for multiple holes
- Double pipe connected by U-bend inserted down multiple drill sites
- Depth of holes dependant on soil/rock condition & system size
- Only digging required is for header trench where pipes join

Open Loop (Water Well) System
- Requires abundant supply of well water
- Discharge well such as a stream or pond required
- Potentially the most cost-effective option up front, if well equipment requirements are met.

Customer Testimonials
Buchanan & Hall are the local leaders in geothermal energy. Their knowledge and guidance was valuable in providing sustainable, low-impact, and efficient energy to our guests, and their willingness to collaborate with us to balance aesthetics, design, and functionality was impressive.
Project Lead at The Penrose Suites - St. Marys, ON
I would recommend Buchanan & Hall because of the people. Without a doubt, you can be assured that the culture at Buchanan and Hall will mean everyone from the company makes sure you get what you need, and have it done professionally.
The next home I build will include Buchanan and Hall from the beginning for sure. The crew were respectful and kind. The house was left clean and all garbage removed by the crew. Everyone was polite and they didn't mind working around my large pets.Geothermal Customer - Mitchell, ON
This company is amazing to deal with. I made an inquiry by phone. The lady I spoke to was so courteous and efficient, taking time to gather detailed information on what was required, and advising she would call us back with pricing and dates. She was true to her word and called back very promptly answering all our questions and a service date was scheduled. The service did not stop there - the service tech. was also courteous, efficient and knowledgeable. After changing filters and checking the Hepa system, he also checked the HRV system. As we are fairly new to this home and did not know much about the HRV system, this gentleman took time to explain settings and how to make it work more efficiently for us. We already feel the benefit of fresher, cleaner and more breathable air due to the invaluable information he provided. In this day and age where it seems difficult to get good service, this company excels at it and made us feel valued. We would highly recommend them and will definitely use them again when service is next required.

Geothermal Customer - Puslinch, ON
I would like to thank you and all of your employees involved in my geothermal experience. Every aspect, from the initial consultation to B&H participation in the open house, was professional, friendly, honest, courteous and of course, knowledgeable.
Geothermal Customer - Mitchell, ON
We chose Buchanan & Hall to install new refrigeration units. We also had them install new fans, a condenser system, line the butcher shop walls with insulation and install a coil, plus upgrade the walk-in refrigerators and freezer. Excellent service, workmanship and company integrity as they helped remove the old units, ran new water and drainage lines, and made sure everything worked perfectly once the new units were installed.
Owner, Paisley Freshmart - Paisley, ON
My geothermal system just keeps on working year after year.
Geothermal Customer - Stratford, ON

Geothermal Customer - Lakeside, ON
Thanks again for staying very on late on a Friday evening to repair our WaterFurnace. Without your determination and stamina, we might still be dealing with our unrepaired unit. The unit is working very well again. Take care and best regards.
Geothermal Customer - Kirkton, ON
I appreciated how super polite the guys were. Andrew, Jason and Jesse represented Buchanan & Hall very well.

Thanks for dealing with my heat pump before the warm summer. And thanks to Patrick and Dylan for installing it. I’m glad to know that when hot days arrive, I’ll be ready.
