19 Years of Excellence in Heating and Cooling Services

Since 1991, Custom Mechanical Services has grown to become a leading, full service, “Green” HVAC and Plumbing company. We’re available to both home owners and commercial industries statewide in Connecticut, providing top-notch heating and cooling solutions.

Your home or building is a valuable investment- take care of it and make it more comfortable and energy efficient. Custom Mechanical Services is licensed in CT to perform repairs, maintenance, retrofits and new installation on all types of heating and cooling systems including geothermal heat pumps.

Moving Forward with Green HVAC Technology

Our philosophy is that preserving the environment should not come at the cost of anyone’s personal comfort. That is why we fully stand behind the quality of WaterFurnace Geothermal systems, which have the highest energy efficiency ratings in the industry.

As a leader in “Green” installations we also service and install solar hot water systems from Oventrop. Let us show you how the investment in a solar hot water system will help to lower your utility or oil bills.

We also deal in the highest quality, energy efficient heating and cooling systems from TRANE.

We are an IGSHPA Accredited Installer. The International Ground Source Heat Pump Association (IGSHPA) is a non-profit, member driven organization established in 1987 to advance geothermal heat pump (GHP) technology on local, state, national and international levels.
