Why Choose McCormack For Your Contracting Services?

The simple answer is our history of quality execution. McCormack provides the following energy-saving contracting services in bundled programs and on a stand-alone basis.


Upgrade your HVAC unit to reduce ongoing maintenance and energy costs.  HVAC systems can be included and financed with our comprehensive energy packages.

Even if your air conditioner is only 10 years old, we can help you save 20% to 40% on your cooling energy costs by replacing you existing unit with a newer, more efficient model.

We offer air conditioning and heating systems from manufacturers such as Trane, York, Lennox, Carrier, AC Pro and Maytag. We also offer Quiet Cool Whole House Fans which can reduce your air conditioning usage by 30-50%.

Attic Insulation

By adding attic insulation and sealing air leaks, we can help you cut heating and cooling energy bills by up to 20%.

The performance of a new roof goes a lot deeper than new shingles. Did you know up to 40% of a home’s conditioned air escapes through the attic? Our trained crews can install your added insulation in usually a few hours. Care is taken to install barriers around and protect any potential hazards such as lights, heaters etc.  The benefits of additional insulation are reflected immediately in reduced energy bills, making the payback on one of our combination solar roof installations even quicker.

Windows & Doors

Refresh the exterior and interior of your property by installing new energy efficiency windows and doors

We can install Energy Star windows to help you save on utility costs throughout the year.  Energy Star studies show that replacing single pane windows with double pane can save between 21% and 31% off of heating and cooling costs.

Exterior Painting

Refresh the exterior of your property and reduce energy demand at the same time. Our painting services include expert preparation, caulking, sealing, sanding, treating of dry rot, wood replacement and more.

We can paint the exterior of your property with an aesthetically pleasing color of your choice containing solar reflective particles.  This type of paint (or coating) can reduce your cooling cost.  Based on an analysis of more than 100,000 building simulations, scientists at Lawrence Berkeley National Laboratory found that in the West Coast climate zones, “cool walls” can lead to annual HVAC energy costs savings of up to 8.3% for single-family homes and 4.6% for medium-sized office buildings.

LED Lighting

Improve the color tones of your lighting and dramatically cut your energy demand.

We can replace your Fluorescent Tubes, compact florescent bulbs and incandescent bulbs, with state-of-the-art LED lighting as part of our energy upgrade packages.
