Why industrial duct cleaning is worth it

Reduces electricity costs

When you regularly maintain your HVAC system, you save money on electricity bills. Our technicians can clean the dust from the inside of components during a tune-up.

Improves comfort indoors

We inspect the thermostat feature during maintenance visits to make sure your device is reading temperatures correctly and reacting properly.

Lower the risk of repairs

Every part of your HVAC unit will be carefully inspected by our service technicians. We’ll take care of any pending issues right away, rather than waiting.

Extend equipment longevity

Arranging for a cooling tune-up in the spring can help you get the most out of your air conditioner and furnace before the summer heat sets in.

Frequently Asked Questions

Vacuuming is a pretty common way to clean things, but there are several reasons why this isn’t a good idea. First of all, vacuuming is not going to remove all of the dirt and debris that has accumulated in your system.

Second, vacuuming can actually end up making the problem worse, as the dirt and debris gets stirred up and can end up recirculating through your air ducts. Finally, vacuuming won’t be as effective as an expert commercial air duct cleaning. Professionals have the tools and expertise to remove all of the dirt and debris from the system and leave it clean and free of potential problems.

Mold can be difficult to spot and can cause serious health problems if not addressed. There are a few things that can cause mold to grow in air ducts, such as:

  • Leaky pipes
  • Condensation
  • Damp insulation
  • Poor ventilation

If you suspect that you have mold in your air ducts, it’s vital to contact our technicians to perform a thorough analysis and conduct a commercial AC duct cleaning as soon as possible. This will help to prevent the spread of mold throughout your property and also help to improve the quality of the air you breathe.

There are a number of benefits that come from having a clean HVAC system. When airflow is restricted, it can cause the system to work harder to maintain the temperature inside the building. This can lead to higher energy bills and increased wear and tear. Regular commercial air duct cleaning can help to prevent these problems and keep energy costs down.

In addition to improved airflow and energy efficiency, it can also improve indoor air quality. Air ducts that are full of dust and debris can release those particles into the air, causing them to be breathed in by occupants. This can lead to a number of health problems, including allergies, asthma, and respiratory infections. Keeping the air ducts clean can help to reduce these risks and provide a healthier environment for everyone in the building.
