Can Air Conditioning Spread Covid?

The Covid-19 crisis required us to rethink how we protect our health at work, how we can prevent the transmission of pathogens through ventilation and air conditioning, but also the importance of correct sizing of fresh air flows in the room.

Given the airborne mode of SARS-CoV-2 virus transmission, HVAC systems can contribute to the spread of the virus. Paradoxically, it may also contribute to the reduction of the transmission rate. Small particles can be transmitted through ventilation systems, as has been shown in tuberculosis, measles, influenza and typhoid fever. Therefore, a prerequisite for any protection strategy in buildings is that the HVAC system is well designed, executed, put into operation and routinely maintained.

Here are the recommendations from a trusted heating and cooling Denver company for the operation of building installations:

  • Increase the inlet/ outlet air flows in the ventilation systems. Intensifying the ventilation rate with fresh air from outside is useful, as it helps to dilute the concentration of virus particles in the building and even on surfaces.
  • Use heat recovery systems with caution. Under certain conditions, virus particles from the extracted air can re-enter the building. Heat recovery systems can carry the virus attached to the particles from the exhaust air to the inlet, through leaks/ infiltration.
  • Air re-circulation modes must not be used.

Considering the Composition and Make Up of Common HVAC Filters: Are HVAC Filters Recyclable?

Image
As the consistent effort of trying to recycle every type of material and product that we own continues, there are worries that some products simply cannot be recycled. That is the case for HVAC filters, but if you ask an actual HVAC contractor, they can tell you that there is a lot more to the story than just that. The problem starts when we evaluate the chemical composition of the filters. Most HVAC filters are designed to use various types of woven fibers to keep unwanted allergens and dust particles away from your home. This means that most of them can’t be recycled from the start, as the polyester and fiberglass compounds are not recyclable at all. Another issue has to do with the actual harmful compounds that the filter often captures in its fibers. The general consensus of licensed furnace service Denver contractors is that, in order to avoid spreading these compounds, dust particles and possibly even viruses, you have to dispose of the filter in a plastic bag that you seal c...

What Should You Try When Your Heating or Cooling System Doesn’t Turn Off?

Image
When the AC or heating unit doesn’t turn off, it’s usually a problem with the thermostat. As it gets older, for example, an AC/furnace unit still relies on relay switches to maintain the communication between the thermostat and the fan. As time goes by, these switches may become damaged or even unusable, in which case they will prevent that communication entirely. If that happens while the fan is on, then it’s possible for it to stay on, as it no longer receives the command to stop when you turn it off. There are other considerations as well. In case only your AC unit doesn’t turn off, there may be an issue with its condenser coils. Since the AC system relies on the use of a condenser to remove heat from the air, it’s possible that hot air is no longer removed from the air, so the AC becomes stuck in an endless loop  trying to keep seeping away heat until it gets confirmation from the thermostat that the target temperature has been reached. It’s also important to check the fan l...

Are A/C Warranties a Good Deal?

Image
For air conditioners there are two types of warranties: factory warranty covering the equipment and spare parts installation warranty from the installer, which refers to repairs related to installation, refrigerant route or electrical connections For your protection, air conditioning repair Denver technicians suggest that you insist on receiving a written warranty for both equipment and installation. Warranties are important because they cover all defects of mechanical or electrical nature, under the conditions described in the warranty certificates issued by the manufacturer. The warranty refers only to the air conditioner for which it was purchased, and which can be identified based on its serial number, the manufacturer’s warranty certificate and the purchase invoice. The product must also be in its original configuration and have not been damaged or subject to unauthorized interventions. An air conditioner covered by a warranty benefits from an intervention period. If the...
