"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
If your AC runs constantly, it could be due to a number of things, including a faulty thermostat, incorrect temperature settings, or broken equipment. Alternatively, you might have an airflow problem (for example, blocked vents or leaky ductwork). Either way, an HVAC pro can identify the specific problem and fix it for you.
The time it takes to clean your AC unit depends on factors such as its size, the level of dirt buildup, and the thoroughness of the cleaning process. A basic cleaning can take anywhere from 30 minutes to an hour, while a more detailed cleaning involving disassembly and deep cleaning may take a few hours. Make sure you allocate enough time to ensure all components are properly cleaned for optimal efficiency and longevity of your AC unit.
Yes. Your air supply should be balanced. The return and supply ducts need to maintain that balance, and this only occurs because an equal amount of air should be entering and leaving your HVAC system. Changes in pressure, extreme weather, and blocking vents with furniture or your stuff can make the air supply unbalanced and cause your home to get too cold or hot.
After you clean mildew or mold that appears in your home, you expect the nasty odor to disappear, too. Sometimes, though, the odor can linger after cleaning. To get rid of a mold smell, you may need to clean the area every few days for a few weeks. Use a dehumidifier or fans to try to remove moisture from the area. If the odor remains after a few weeks, you may still have mold or mildew in the area. Call a mold testing professional for another inspection.
Duct sealing is essential for most homes, but urgency can vary depending on factors like the age and condition of your ductwork. In older homes, ducts have probably developed leaks and gaps over time, making sealing crucial for energy efficiency and indoor air quality. Even in newer homes, sealing can help to prevent potential issues down the road and improve your HVAC system’s overall performance.
