Commercial & Industrial Buildings Are Our Specialty

With over 28 years of experience in commercial HVAC installation, renovation, and repair we know how to clean your commercial systems.  No matter what kind of system you have, we have the expertise to clean it.  We’ve run across many issues in the commercial market.  Each building has its own story.

  • One corporation hadn’t cleaned their cooling tower in two years and had 3 inches of sludge on the bottom.  Not a problem.boiler cleanout small
  • Another customer had a confirmed case of legionnaires’ disease and needed their HVAC system sterilized.  Not a problem.
  • One customer had a fresh air intake close to the ground that had been sucking up dirt for 20 years.  Their entire HVAC system was contaminated so badly that balls of dust were blowing out of the registers onto people’s desks and into their coffee in the morning.  Once again, not a problem.

What you can’t see can hurt you

A building’s air duct network acts as its respiratory system. Dirt, dust, debris, and microbial growth accumulate inside of air ducts hidden from view “congest” the system and make it difficult for the building to “breathe” properly and function efficiently. In fact, a 1987 ASHRAE study concluded that maintaining system cleanliness would reduce average operating costs by 10 to 25%.

More than 70% of all IAQ problems involve the HVAC system. Dirty air ducts are an ideal breeding ground for mold spores, mildew, bacteria (including Legionella) and other health-threatening microbial growth. Dirty ducts can also result in higher utility bills, reduced air supply and premature failure of expensive HVAC components.

What does ASHRAE Say?

ASHRAE Standard 180 put out in 2012 recommends inspecting the duct annually or more depending on the activities in the building and cleaning as needed.  How old is your building?  When was the last time you had your HVAC system inspected for cleanliness?  Do you know if it needs cleaning?  Let Pur-Vent handle that for you.  We’ll inspect your system and provide a final report with pictures and lab tests of any possible mold found.  This confidential report would be delivered to your maintenance supervisor so that administration can decide how to proceed.  If no cleaning is necessary then that’s great for you!  If the system is contaminated then we can move onto the next step of getting it clean.  Once again You win!

The Solution: Clean air ducts for cleaner air.

So what does this mean to your bottom line? Studies have shown that a regular cleaning of the HVAC system can save around 25% on heating and cooling costs. Furthermore making the indoor air healthier will cut down on distractions due to allergies in the workplace and contribute to employee morale. This will decrease losses due to sick days and make your bottom line look better.
