The Pros and Cons of Constantly Running Your HVAC Fan

Running Your HVAC Fan

Some people are big fans of running an HVAC fan continuously, especially to reduce indoor allergens. Should you? Here are the pros and cons:

Pros:

• Less start/stop stress on the fan.
• Consistently cleaner air because of constant filtration.
• Keeps the ambient air at a more even temperature.

Plus, learn these 21 air conditioner maintenance and home cooling tips.

Cons:

• Higher cost. With a 500-watt motor, this can be significant!
• Shorter furnace filter life.
• In summer, the continuous running may mean circulation of air that is warmer than the ambient air, causing the A/C to kick on more often.
• In winter, the air being circulated may feel colder when the furnace isn’t running.

Why old homes can save big money with an HVAC update.

Some newer thermostats have a “circulate” function, which runs the blower at a slower speed, reducing wear and tear and limiting the cost of running the fan full-tilt 24/7.

When your air conditioning, heating or ventilation systems go on the fritz, it can seem like you’ll have to put the handyman tools away and call in the professionals. But sometimes the problems with HVAC systems can be repaired on your own! Here are 12 HVAC troubleshooting tips to consider before you call an HVAC tech.
