Image for Maintain a Healthy Indoor Air Environment With Aeroseal to Prevent Mold

Mold is a fungus that harms any indoor environment, including homes and commercial buildings. Microscopic mold spores build up in a warm, dark, humid environment. Homes and commercial buildings throughout the south, from Florida to Virginia, are perfect breeding grounds for mold, mildew, and other microscopic pathogens that can enter through cracks and tears in your ductwork. They blow into rooms through the return air ducts in the HVAC system, compromising a healthy indoor air environment.

There are more than 30 species of mold and mildew. These particulates, dust, and pollen are not always trapped in the filter systems.

You can breathe mold spores, dust, and other pathogens without being aware of the damage this irritant is causing in your body until you experience symptoms.  Some reactions to mold inhalation are similar to dust and pollen allergies.

  • sneezing
  • coughing
  • asthma attacks
  • chest congestion
  • difficulty inhaling
  • eye irritation
  • skin rashes

In addition, you can often smell the musty mold. You can see slimy black mold growing on walls in rooms where it has not been prevented.

Kitchens, bathrooms, and other rooms with a high moisture content are subject to mold growth. This includes basements, and garages as well as interior walls. Be vigilant in many areas of your home to prevent mold growth. It is easier to control if your HVAC system has sealed air ducts.

Mold Prevention

Aeroseal seals air ducts with precision in residential and commercial heating ventilation and air conditioning (HVAC) systems to maintain a healthy indoor air environment. This prevents mold spores and other pathogens in the air, along with excessive moisture, from entering the ductwork. Aeroseal seals the tiniest tears in ducts that can allow moisture and spores to penetrate. It can reach even inaccessible sections of the ducts.

The science behind Aeroseal’s efficiency is based on fluid dynamics. Pressurized airflow propels the aerosolized sealant particles through all ducts. The sealant automatically fills in any tears or breaks in the duct surface. The sprayed sealant also provides a moisture barrier in the ducts, as it closes off these areas.

Protection for HVAC systems

Sealing ductwork protects the HVAC system from deterioration, as well. Invasive humid air that supports mold growth on the walls of ducts can ruin them, and they have to be replaced. In addition, the system with mold buildup in ducts must work harder to heat or cool rooms. This consumes more energy.

Ducts in commercial buildings are much larger than home HVAC systems. A small leak in one area of the ducts can cause mold, dust, and other particulates to spread throughout a building, compromising a healthy indoor air environment. It is often difficult to locate the source of the leak.

Keep drip pans in commercial air conditioning systems clean to prevent mold from growing in this damp area. Mold spores spread through an HVAC system with cracked or torn ducts can find a comfortable place to grow in a room, especially a damp basement, with a drip pan.

Mold can spread quickly in a damp environment to ruin walls and floors. Professional mold remediation is necessary to clean this area before the mold is carried back into the HVAC system, where it can spread to different rooms. Trained mold removal professionals wear hazmat suits to clean extensive mold from walls and floors!

Keep Ductwork Sealed

Aeroseal is a sustainable way to keep your HVAC ductwork sealed and clean in both commercial and residential buildings. Take a proactive approach to prevent mold and moisture buildup.

Contact us to find the HVAC service company near you to apply Aeroseal to your ducts. A healthy indoor air environment is necessary for good health.

Paul is hands-down the best AC technician I’ve ever dealt with! He’s incredibly honest, super knowledgeable, and genuinely looks out for his customers. When my unit started acting up, he took the time to explain everything clearly, showed me exactly what needed to be done (and what could wait), and didn’t try to upsell me on anything unnecessary. His prices are fair, he shows up on time, and the work is top-notch. It’s obvious he takes pride in what he does and truly cares about keeping his customers comfortable without breaking the bank. If you need AC maintenance or repair, call Paul—you won’t regret it! Highly, highly recommend.

We loved Air Boca so we were thrilled when they joined forces with another company and became Aztil Air! Our technician was Paul and he was great! Good with the dog, made solid recommendations around what needed to be done, tip-toed around the house when we got on our conference calls. We are very happy with our service!
I’ve been a customer on their maintenance plan for probably 7 years. Always been a positive experience.

My old HVAC system finally died so I called Aztil to give me a quote on a new system. The salesman recommended a system I’d never heard of called Daikin. He promised it would cut my electrical bill in half. He was right. However, there was an unforeseen side effect with the Daikin. Simply put, the system is not suitable for the humidity we have in South Florida. It became a mold manufacturing machine, both in the unit itself, and throughout all my ductwork.

Working with a manager, Sabrina Cordetti. We attempted all sorts of solutions, but nothing stopped the continuous mold production.

Ultimately, Aztil did something that knocked my socks off. Jack, the service manager and Sabrina called me to tell me they were going to replace my system at no charge with whatever system I wanted!

I sent them the specs from the original system which had done an amazing job keeping my unit as cool as I wanted it to be during the heat of summer and they agreed to install the same unit but the new version.

The total bill came to over $15,000 and no charge to me!

Can you beat that kind of integrity and customer service? It really is unheard of in this day and age.

The culture at Aztil is clearly to take care of their customers, to well train their technicians, and to maintain the highest level of integrity and customer service.

A++++++

I had an AC issue the day before Thanksgiving but Ramon was able to come the night before and get me up and running again. He was incredibly professional and personable. He let me know I desperately needed the UV light installed in my system. We went ahead and scheduled everything for a Friday install. My technician, Alex, came out earlier than expected (not complaining at all) and got everything cleaned and installed in no time. Professional and efficient. Both guys were amazing. A big thank you to both Ramon and Alex.
