Stay Green, Save Energy

Going Green: Saving resources and saving you money!

In 2008, Controlled Release Technologies embarked on a massive research program to reformulate their entire product line to conform with today’s Green standards.

The effort continues to be time-consuming, but two of their many products that are independently-certified as green as of this writing. These products are PanGuard® and First Strike MicroCoat®.

Pancrete by CRT

HVAC equipment represent an expensive and required addition to commercial and industrial buildings. After ten or more years of operation, systems become corroded shortening their usable lifespan. This premature replacement strains budgets.

Pancrete stops corrosion and adds years of additional equipment life.

Change your air filter regularly

Check your filter every month, especially during heavy use months (winter and summer). If the filter looks dirty after a month, change it. At a minimum, change the filter every 3 months. A dirty filter will slow down air flow and make the system work harder to keep you warm or cool — wasting energy. A clean filter will also prevent dust and dirt from building up in the system — leading to expensive maintenance and/or early system failure.

Q: How often should I recharge my air conditioner with new freon?

A: Contrary to popular belief, air conditioners do not consume refrigerant (freon) as a car consumes oil, so under ideal conditions it would never need changing or filling. Therefore, a low freon level indicates a leak which should be repaired before adding more. While most new system connections are welded to minimize leaks, many older units (8+ years) were connected with mechanical flared fittings which can vibrate loose over the years, causing leaks.
