How much do HVAC companies charge?

• <div><p>HVAC technicians charge around <b>$175 per hour</b>, but anywhere between <b>$100 and $250 per hour</b> isn’t uncommon. The total cost of your HVAC service depends on the type of work, the type of system, and more. Here are some important cost factors to consider to get accurate pricing:</p><ul><li><p>Time of year</p></li><li><p>Urgency of your repair or service</p></li><li><p>Type of system </p></li><li><p>Type of repair you need</p></li><li><p>Whether or not you have a service contract</p></li><li><p>Size of your HVAC system</p></li><li><p>Brand of HVAC equipment </p></li></ul><p></p></div>

Can I close vents to deflect air?

• <div><p>No, because closing air vents could damage your HVAC system. Closing a vent will only keep the air in the duct, not redirect it to a room or zone where you’d prefer it to be. That air will become trapped within your ductwork, creating a buildup of pressure that can damage the ducts and cause leaks. </p></div>

Q: Who sets the guidelines for air changes per hour?

• <div><p>The American Society of Heating, Refrigerating, and Air-Conditioning Engineers, or ASHRAE, sets the standard guidelines for air changes per hour in homes and businesses. The International Residential Code, or IRC, also sets ACH requirements for residences and bases those requirements off of ASHRAE standards plus climate specifics related to your location. </p></div>

Q: How do you fix a weak AC airflow?

• <div><p>Dirty filters are almost always the cause of poor airflow, so they should be regularly cleaned and then replaced as needed. The fan blades can also get dirty, so they should be cleaned when the unit is turned off. Make sure that the outdoor area around the back of the unit is unobstructed. Trees, shrubs, trash, and other objects could be too close to your unit.</p></div>

Q: What is a healthy air change per hour?

• <div><p>Healthy air change per hour, or ACH, rates vary by room, usage, average occupancy, and volume. The minimum ACH that's considered healthy averaged throughout the home is 0.35. However, in rooms where humidity is an issue, such as bathrooms and kitchens, healthy ACH levels are between eight and 15. </p></div>
