FAQs
What is BTU for air conditioners?

A British thermal unit, or BTU, is a unit of measurement that calculates the energy needed per hour for an air conditioner to remove heat from the area. It is recommended to have an air conditioner that uses 20 BTUs for each square foot of space in order to have proper cooling.

How often should commercial HVAC filters be changed?

In an indoor environment that is controlled, it’s best to change filters three to four times a year. For harsher outdoor environments or locations that have highly active HVAC systems, filters should be replaced more frequently.

Do air conditioners emit carbon monoxide?

No, your ac unit cannot emit carbon monoxide because it is not burning fuel to create harmful gases. However, heating equipment can produce carbon monoxide, so it is important to install professional ducting systems to keep your crew safe.
