How the Increased Use of HVAC In Winter Creates More Allergen Buildup

Facility HVAC Management in Winter - AllergenThe results are in and according to groundhog legend, we’re in for a few more weeks of winter. That’s not welcomed news for some in this country as snowstorms have already extended into regions of the country rarely experiencing anything but the odd flurry. Hazardous weather keeps many people indoors for days and sometimes weeks, without any fresh air. This means HVAC systems and furnaces must work overtime to keep the air warm while maintaining indoor air quality.

With more people indoors, more allergens such as dust, pet dander, and pollen that clings to clothes are created or trapped, then recirculated through the air. Most systems have at least one filter to remove large particulates from re-circulating through the air, but this becomes more difficult in winter when less fresh air is circulated. Recycled air from indoors picks up particles from humans and things like furnishings and fireplaces. If filters are not changed frequently, or incorrect filters used, these trapped particles can build upon system components and cycle through a unit. As the heat continues to cycle on to counter the extreme temperatures outside, the allergens flying around inside will start to cause respiratory complications for those with asthma and allergies.

The inside of a unit, specifically the coils and ductwork,  can become clogged with dust and dirt as filters become clogged and begin to allow particulates through. If this happens, the buildup will also cause efficiency problems for your unit. If left for too long, dirty components can malfunction and even cause a system failure. On heat pumps specifically, this can be catastrophic. Which is why in addition to changing filters regularly in the winter, regular HVAC maintenance should be done prior to the winter, and not just the spring. This includes checking for a clean interior prior to and after winter months, cleaning coils (where needed) and making sure filters are changed. In a heat pump or split system especially owners will want to make sure seasonal maintenance is conducted before switching from heating to cooling.

After the long months of winter use, vacuuming and cleaning out the interior ductwork of your system will keep it running efficiently. Additionally, cooling and heating coils can also become clogged with dust and dirt, and should also be inspected and cleaned at the change of the season with a specialized coil cleaning system. Goodway has cleaning systems for any type of HVAC unit. They also have an onsite engineering department that can advise on products and proper maintenance and usage techniques. If you’re concerned about the indoor air quality of your facility during the long winter months, give them a call to find the right cleaning solution for you.

Why Disinfecting Schools May Require Industrial Grade Disinfectants

This flu season is one of the worst in over a decade, and our schools have seen the worst of it. Unlike previous seasons, the current strains of influenza are affecting seemingly healthy young people, even those that have had a flu shot. At least 9 schools in Texas have closed for at least one day due to the number of students absent with flu. Experts say cases likely ramped up in January due to children returning to school and estimate we have several weeks left in this flu season to go.

The Importance of Duct Cleaning for Indoor Air Quality

This winter could break temperature and snowfall records across the country. For most of us, staying inside is the only defense. Avoiding the outdoors may keep us safe from dangerous weather, but we face another danger from the inside. The air quality inside a building begins to worsen when there are less fresh outdoor air and an increase in people and animals. Poor air quality is not only uncomfortable but can be bad for your health.

Facility Manager Talent Gap Brings New Initiatives in 2018

The facility management field will continue to grow in 2018 while the talent pool shrinks. Historically there has been no linear path to a career as a facility manager. Generally, experienced trade professionals are promoted to facility management based on knowledge and experience. But now as many seasoned facility managers hit retirement age and building management becomes more automated, fewer knowledgeable and experienced candidates can fill the growing number of facility management positions.
