"They were able to clean some of the ducts, but explained some ducts needed completely replaced due to the mice. Replacement was not a service they did, but they did supply the name of a company to contact for replacement. They were very honest, only charged for the services they provided. I would recommend them again and will use them again myself."

"It went very well. I met with Sergio and he explained everything very well. He went into attic to inspect and found asbestos. He sent someone out to remove it. I was glad he pointed it out to me because I found it can cause cancer. He assigned someone from the office and she scheduled all the appointments including the inspection that was done today. They cleaned up every time they left my house and it looked like they were never here. They were really professional and always on time. They were just a great company overfall."

"When Mary Poppins needed a Chimney sweep she called her guy. When I needed one I called Chimney Sweep Masterâ s, Jonathan! He was fast to respond, schedule and show up for the job. To avoid being late by way of an employee that was understandably behind do to a rain storm he showed up hisself! He did an inspection, a sweep and a sprucing up of the fire place with a fresh coat of paint all in two hours!!! He even checked my drier vents as he is â full serviceâ !!!! And just like thatâ ¦. I am ready for winter!!"

Air Duct Cleaning FAQs, answered by experts

If you don't clean your air ducts, contaminants like dust, allergens, and mold can accumulate, reducing your home's indoor air quality. Your HVAC system will circulate this dirty air, which can affect your health. Trapped moisture can also lead to mildew and mold growth, especially in humid climates. Additionally, clogged ducts can strain your HVAC system, causing it to run inefficiently, which increases energy costs and can potentially lead to a complete system breakdown.

HVAC companies may charge an hourly rate or a flat fee. Hourly rates typically range from $100 to $250 per hour, with an average around $175. Some contractors charge a flat fee for specific services, such as an inspection, which can cost between $150 and $500. The total cost of an HVAC service is influenced by several factors, including: the urgency of the service (emergency repairs after hours or on holidays cost more), the time of year, the type, size, and brand of your HVAC system, the specific repair needed, and whether you have a service contract.

Musty smells often indicate the presence of mold, which can lead to various health risks. Inhalation of mold spores may trigger allergic reactions, causing sneezing, a runny or stuffy nose, and itchy or watery eyes. People who suffer from mold allergies or asthma may experience more severe respiratory problems. Certain types of mold, like black mold, can lead to mycotoxicosis, a condition associated with serious health effects like respiratory problems, fatigue, headaches, and skin irritation if exposure continues for an extended period. Those with weakened immune systems, respiratory problems, or allergies may be more vulnerable to the health risks that come with musty smells. Therefore, it is crucial to address and eliminate the source of the odor promptly.

A mild skunk smell in your house can last up to three weeks, dissipating over time with proper ventilation. However, if you leave stronger smells untreated, they can last for months or years, becoming more difficult to remove the longer they sit. This is especially true of odors that have seeped into fabrics such as clothing or furniture or those in your pets’ fur.

Mold in your air conditioner isn't a good thing, as it can be harmful to your health. If the mold travels through the ductwork or is blown out of the A/C, you and your family can inhale mold spores and develop respiratory illnesses and other problems. Preventing mold from growing in the air conditioner will help protect your health.
