C2G Environmental Consultants, LLC specializes in underground storage tank removals and abandonments, above ground storage tank removals and installations, remediation of contaminated soil, groundwater investigations, and emergency spill response. By choosing C2G Environmental, you can be assured that your environmental project will be handled with the utmost care and professionalism. C2G Environmental is a full service environmental company. What sets us apart from other companies is our highly trained staff of professional geologists and hydrologists, as well as technicians. We do not use sub-contractors or rental equipment. We are authorized by New York, Connecticut, and New Jersey to remove and haul contaminated material. Our Services: Tank Removals, Abandonments & Installations, 24 Hour Emergency Spill Response, Ground Penetrating Radar (GPR), Geoprobe & Vac Truck Services, Water, Soil, Air Testing/Monitoring , Liquid/Soil Transportation & Disposal, Petroleum Facility Compliance Audits (Class A/B Operator), Phase I & II Environmental Site Assessment, and more.

"This review was 5 stars until about a week ago. I needed a new oil tank installed last year. C2G came out and performed the task. They were the most cost effective option so I went with them. The install was a success and the tank looks great. However, a couple weeks after I had to have them back out again to fix the leaking oil filter. They came out, tightened it, and it stopped leaking... for that period of time. Fast forward to this year and getting ready for the colder months. I noticed a small puddle underneath the filter, again. This would be the 3rd time I would have needed them to come out to repair it. At that point I question if it was installed correctly or not. I called them asking if they could come out, they said with a fee and showed opposition in understanding where I was coming from, saying I was outside of their 45 day guarentee. The lady I spoke with said she would speak to her supervisor and follow up with me. That never happened. I had to have a plumber over to my house, and luckily he was able to repair the leak. The rubber gasket was malformed inside, causing the slow leak. Despite a smooth install, I was really disappointed with how they treated a previous customer. They really didn't care that their work was sub-par. A newly installed oil tank should not be leaking a year later. I will not use this company again."

FAQs for geothermal heating or cooling system installation projects in Cornwall-bridge, CT

Homeowners should consider several factors before investing in a geothermal system. If the upfront costs are in your budget and you plan to stay in your home long-term, you’ll likely get a better return on investment. New home construction is also ideal for geothermal heat pumps because these installations often cost less than retrofitting.

The total time it takes to recoup your costs depends on your upfront investment, energy savings, local climate, utility rates, and other factors. Most heat pumps pay for themselves within 10 years, but it can take up to 15 years.

Geothermal installation takes one to six weeks, depending on the system type, site conditions, and installation complexity. This process includes excavation or drilling, connecting piping, and configuring the system, so your contractor may leave heavy machinery and other equipment on site until it’s no longer needed. Assessments for your system may occur several months before the installation.
