About Effectiv

Who We Are

EffectivEnergy Solutions is a full service HVAC engineering and energy efficiency consulting firm with expertise in HVAC efficiency, energy conservation and simplified operations. We help large facilities to maximize their energy savings and minimize their carbon footprint through innovative and cost-effective designs.


We take a strategic approach to every energy consulting project; first getting to know the client's needs and each building's unique energy profile and then presenting a customized, long term Master Energy Plan. 

Effectiv was founded by Bob McGreevy, a Professional Engineer with over 40 years of experience in HVAC engineering and design. Bob is the acting President of the firm and has an undeniable passion for energy conservation and developing sustainable communities.

We primarily serve the Mid Atlantic and North East regions out of our offices in West Chester, PA and Princeton, NJ.

“I have found the Effectiv team to be innovative and open minded, designing their solutions specifically to meet the unique needs of each situation. They are very team oriented, taking input from our team and incorporating our suggestions in the design rather than take a one size fits all approach.”
- Facilities Manager, PA School District

The energy conservation measures we recommend are not only cost-effective, but make a positive impact on our environment. We work to save the planet, one building at a time.

Serve Others

Effectiv is built on the lasting values of respect, accountability and responsibility. We uphold these values with our customers, our employees and our fellow people.

When you work with us, you help to improve lives in rural Haiti

Over the past four years, we have joined a partnership between Americans and rural Haitians, to support high school education and tree planting initiatives.
