Pelletier Mechanical Services, LLC was founded in 2004 and has provided the Greater Waterbury area with quality HVAC services for 20 years.

In 2025, to reflect our brand’s values and purpose, we rebranded as Perfect Timing Heating & Cooling! Throughout our 20 years we've maintained a reputation for excellence and held ourselves to the highest of standards. Don’t worry, Gary is still the owner and president of Perfect Timing!

You can count on Perfect Timing Heating & Cooling to always be available when you need us. Unlike other contractors, we guarantee our work, all of our installers are licensed, and we guarantee your satisfaction with a 2-year warranty for all residential installations! 

We also believe that it is very important to give back to the community. Therefore we have consistently made an effort to stay involved. Some parts of the community we're involved with include:

• Local Rotary Club

• Thomaston Little League

• Local New Beginnings Program

• Thomaston Food Bank

• Thomaston Cub Scouts
