The history and path to our company began approximately 25 years ago. My background started in construction and painting, and with more experience throughout the years I began running all aspects of construction. Over the course of the last 10 years because of the economic situation, I expanded my experience into the fields of restoration, such as smoke, fire, water, and mold remediation, and not to mention meth lab remediation. Through all of this time I also ran side jobs, all the while successfully running and maintaining other companies. With all of the aforementioned experience that I have obtained, I eventually decided to start my full service company which is A1 Environmental Restoration. Our goal is that you as a customer can experience the small business sincerely wanting your business attitude, that we also offer with big business experience. We will never lose site of this goal, no matter how much we grow. Sincerely, Andrew J.C. Gray

Air Duct Cleaning questions, answered by experts

It isn’t a good idea to never clean your ducts. Most appliances have filters for a reason—to clean the air—and over time, they lose their effectiveness. They may eventually become so clogged that your HVAC system will stop functioning correctly or shut down altogether. Cleaning your air ducts is also a requirement if you want clean air in your house. Thorough cleaning checks are recommended to make sure the air is safe from any toxic or harmful contaminants.

You will know if your furnace needs cleaning if your furnace seems to be working less efficiently than normal. You may notice your bedroom is chilly, but the living room is extremely warm, or perhaps the furnace isn’t heating the house properly at all. The furnace may also make weird noises, like bangs or whistles, or emit a rubbery or smoky smell when it is dirty. Of course, these symptoms could also be signs of other issues, so call in an HVAC pro to take a look as soon as possible.

You should not spray pesticides of any kind into your air vents. The spray won’t reach far into the vent, minimizing its effectiveness in killing roaches, but more importantly, it’s dangerous for people and pets to inhale these chemicals. Roach spray is not a natural roach repellent, and it’s not safe to spray into air vents.

The number of return air vents a house should have depends on its overall square footage. You'll need one supply vent and one return vent for every 100 to 150 square feet of living space. This means that, ideally, there should be at least one return air vent in every room. However, if the room is 100 square feet or larger, it's better to have two or three. A 2,000-square-foot home should have between 13 and 20 return air vents, in total.

Yes, professionals clean ducts and exhaust fans to ensure complete system efficiency and compliance with safety codes.
