Q: Does cleaning air ducts really make a difference?

• <div><p>Clean air ducts ensure proper airflow throughout your household. They can also remove any built-up dust particles and make the air in your home that much cleaner. Lastly, cleaning your air ducts will help your overall energy cost and ensure your HVAC system works for years to come.</p></div>

Q: Why does my whole house smell like cat pee?

• <div><p>Cat pee has a strong ammonia-like smell, so if you smell cat pee but don&rsquo;t have a cat or don&rsquo;t suspect your cat has any accidents, there could be other issues at hand. Aside from pet urine, your house may smell like cat pee from leaking freon from an old fridge, mold, spilled cleaning supplies, or even outside odors from nearby farms. </p></div>

Q: Is duct sealing necessary for all homes?

• <div><p>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&rsquo;s overall performance. </p></div>

Q: Why do my floors get dirty so quickly?

• <div><p>Your floor sees a lot of action: foot traffic bringing in dirt from outside, pets with muddy paws, kids dropping food crumbs, and more. All of this makes your floors dirty, and if you don&rsquo;t keep up with cleaning them, staying on top of the dirt will become more challenging.</p></div>
