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 window a/c unit installation projects in Montville, CT

Window AC units can use a significant amount of energy. These units use about 12 to 17 kilowatt-hours per day, significantly more than a refrigerator's one to 1.5 kilowatt-hours per day. To keep your energy costs down, run your window AC only when necessary, keep doors closed to contain the cool air, regularly clean filters and coils, and seal any gaps around the unit to prevent cold air from escaping.

Inexpensive air conditioner units are often not worth it. Low-cost products from popular brands like General Electric, LG, Whirlpool, or Frigidaire may be a reasonable investment. However, putting a small, budget-friendly unit in a large room wastes energy and shortens the life span of the AC since it has to draw more power and work much harder to cool the space. The unit will consume more energy and stress the motor and other internal parts, resulting in early breakdown and costly repairs.

The best deals on window AC units come during the fall when businesses slash prices to clear out old inventory. You can also speak with your local AC installer, who may get you a good deal on a window AC unit since they have access to trade pricing. You can also watch for discontinued products and flash sales in your area.

Window AC repair costs between $110 and $390, with most people paying around $250. Parts cost between $2 and $150, with the rest going toward labor, at around $30 per hour. The occasional one-off repair or a routine AC tuneup cost $75 to $200. Servicing can keep your AC running in good condition for several more years before you need to pay for a replacement unit.

Window AC units last eight to 10 years when installed and maintained correctly. High-quality models last up to 20 years with proper care and routine maintenance. The unit’s longevity depends on its construction quality, regular cleaning, and electrical safety inspections. Keeping the filters and coils clean and addressing minor repairs promptly extends its effective performance and ensures reliable cooling.
