"They did not have to dig a trench around my house. They used a machine to inject chemical into soil.

I use this company for my Qtrly pest control also."

Air Duct Cleaning questions, answered by experts
Several factors contribute to the persistent growth of mold in vents, with excess moisture being the most common culprit. Consistent mold formation in vents indicates an ongoing moisture problem within the HVAC system or its surroundings, likely caused by condensation on cool surfaces in areas with high humidity. Moisture accumulation can also result from leaks in ductwork, inadequate ventilation, or insufficient insulation, creating an environment favorable for mold growth. Regular inspections, addressing potential sources of moisture, maintaining proper ventilation, and routine HVAC maintenance can help prevent the recurrence of mold in vents. If the issue persists, seek professional assistance to identify and rectify the underlying problems.
Yes, professionals clean ducts and exhaust fans to ensure complete system efficiency and compliance with safety codes.
Any unexplained smell in your house should be investigated. However, some home odors are "red flag" worrisome because they pose immediate health and safety risks. Odors should be taken seriously when accompanied by headaches, nausea, or lightheadedness. If you smell an egg-like aroma, this is probably natural gas. You should leave the home immediately, and contact your gas company.
If you have a forced-air heating system, it’s important to have it professionally inspected at least once per year. During one of these visits, your contractor will look at all of the components of your HVAC system, including your furnace or heat pump, air conditioner, and ducts. On average, an HVAC inspection costs $300. It’s also important to perform basic maintenance between inspections, such as changing your filters and cleaning dust from around your vents.
If a professional does ductwork cleaning correctly, your home should not be dusty. However, inexperienced cleaners, including DIYers, may dislodge debris without properly containing it. Ensure any pro you hire is certified and has the correct equipment to capture debris instead of just stirring it up.
