### What You Should Know About Your Home’s Air Quality.
#### The air inside your home is often up to five times more polluted than the air outside your home.\*
Today’s homes are built to keep in heated and cooled air and improve energy efficiency. But that also means that more contaminants like mold spores, bacteria, viruses, dust and allergens are trapped inside as well.
#### One cubic foot of air can contain more than 30 million pollutants.\*
These pollutants can cause health problems and aggravate conditions like asthma and allergies.
#### Most standard HVAC system filters do not adequately remove harmful contaminants.†
Standard filters trap only the largest particles, allowing millions of microscopic contaminants to continue travelling throughout your home. Basically, with a standard filter, you’re recycling and recirculating the same polluted air, over and over again.
#### On average, we spend more than 60% of our lives indoors, at home.\*
Without an effective air quality solution, you may spend the majority of your life breathing contaminated air, which can reduce your comfort and potentially lead to health issues. This is especially true during our cold Long Island winters, when we spend even more time inside.
## Breathe Easier with T.F. O’Brien Air Quality Solutions.
With an efficient, effective air quality solution for your home, you’ll:\*
* **Reduce the chances of illnesses** caused by airborne pollutants like bacteria and viruses.
* **Relieve allergies** caused by irritants like pollen, mold spores, dust and pet dander.
* **Enjoy better sleep** since fewer allergy complications can mean more restful nights.
* **Prevent pests** that thrive in dusty, dirty, moldy environments.
* **Improve your home’s energy efficiency** with effective humidity management that can make you more comfortable and help reduce heating and cooling costs.
* **You may also Increase your home’s value** by reducing the possibility of damage caused by pests and improper humidity levels. And since decreasing dust and other pollutants makes homes easier to clean, you may find that you get more free time to enjoy your home.
## The T.F. O’Brien Approach to Air Quality
**While the process we use and the equipment we recommend depends on your heating and cooling system and can vary from one home to another, generally we take a three-step approach.**
We filter the air by installing a highly efficient air cleaner. This is a much more effective solution than standard filters.
We install a photocatalytic oxidizing air purifier to chemically treat the air to remove volatile organic compounds (VOCs), which are the byproducts of common household materials like paint, carpet, vinyl flooring, air fresheners, cleaning products, and more, as well as other pollutants.
We install ultraviolet germicidal lights that kill up to 99% of airborne contaminants like mold, bacteria and viruses.
We may also recommend equipment to regulate your humidity levels.
## Lets get Started.
If you’re ready for a whole-house air quality solution that will ensure a safe, healthy environment your family and guests can truly enjoy, call us. No two homes are the same, and we’ll be happy to send one of our Home Comfort Advisors to meet with you at your convenience to evaluate your unique situation, make recommendations, and give you the confidence to say “come inside for a breath of fresh air!”

Professionalism, Quality, Responsiveness
I'm very happy with the installation of our oil to gas conversion. Matt was extremely diligent in making sure everything was working properly, stayed late, and returned the next day promptly after the installation to resolve a minor issue he identified. Took pride and ownership of his work. I was impressed and would recommend these guys to anyone. The sales experience with Brendan was a good one too. He explained everything thoroughly and made a number of sensible recommendations. No high pressure sales tactics. Accessible and responsive.

We Were Pleasantly Surprised
Last year our central air system went down and were having horrible summer, we ended up calling lots of vendors to come give us quotes. We were pleasantly surprised when one of the owners Chris came himself to evaluate our issues and guiding us on what system we should replace it with. Hence we decided to go with them and we were glad we did. The installer and customer service were beyond friendly and Uber professional. Highly recommended.
**- Amita D.**
I Would Definitely Recommend this Company!
My brother was impressed by their local advertisement. So I called. From the first person to the last person I communicated with, in the company, were kind & warm. Let’s not forget about their expertise & responsiveness. They explained my choices, the cost & the process in a manner I understood without dimming down the info. We ultimately chose to install two new heating units. I would definitely recommend this company!
