Did you know that air quality in your home is 2-5 times worse than outside air? Bad air quality in homes is very common and can lead to some serious medical conditions if untreated. From dirty carpets to chemicals in your cleaning solutions, there are a myriad of ways for your home air quality to become unsafe. Here are some of the warning signs of bad air quality in your home.

Common Airborne Contaminants

Improving bad air quality starts with identifying the individual elements that cause the contamination. Here are some of the more common airborne contaminants in the average home.

  • Dust Mites
  • Pollen
  • Pet Dander
  • Chemicals in Cleaning Supplies
  • Smoke from Burned Food and Tobacco-Based Products
  • Mold
  • Mildew
  • Pesticides
  • Formaldehyde (found in adhesives used to build furniture, carpets and paneling)
  • Polybrominated biphenyl (PBB) & Polychlorinated biphenyl (PCB) (found in many plastics, TVs and computer monitors to prevent them from catching fire)
  • Polyurethane (a respiratory toxin found in many consumer products including sealants for floors and furniture and is also in some mattresses)

Warning Signs of Bad Air Quality

House Guests Are Always Coughing or Sneezing

Have you noticed that when you have house guests, they always seem to be sneezing, coughing or experiencing other symptoms related to congestion and allergies? Do you feel more congested at home than your work or when you are on vacation? If so, that may mean that your home air is not safe for you.

Beware the Aftermath of Home Renovation

If you have recently renovated areas of your home, there are multiple bad air quality factors at play. If you are pulling up carpeting and breaking down cabinets, you are likely unearthing a host of contaminants that have been hidden over the years. Once more, the fumes that are emitted from paint, carpeting adhesive and other renovation products are making your home air more toxic. Be sure to wear a mask and open some windows and doors to keep the fresh air flowing.

Dust Buildup is More Frequent

Have you noticed that dust seems to pile up very quickly in your home? Those in more rural or industrial areas typically see a lot more dust. If you are dusting too frequently, it might be a sign that you need to fit your air conditioning system with stronger filters or UV light. You also may want to consider an air purifier.

How to Improve Bad Air Quality?

There are many tactics that help you toward the goal of having clean, healthy home air including:

  • Change Your Air Filters Regularly
  • Choose Hardwood or Tile Flooring Instead of Carpet, Laminates or Vinyl
  • Purchase an Air Purifier
  • Consider a Ventilator
  • Install a UV Lamp into Your AC System
  • Open Windows When Weather Permits for an Influx of Fresh Air
  • Clean Air Intake Vents Regularly

Oh my god what an amazing company! I literally called one hour ago and said that my thermostat wasn’t working and there was a knock on my door within the hour! They told us what to do to fix it therefore saving us a $600 bill. They came right away, none of that we can see you in 48 hour junk. Amazing.

They were able to provide me with same day service, friendly and very responsive. Also, I got 2 other quotes and the pricing was the most competitive.
So thankful and impressed! My dad returned home after having open heart surgery to a completely dead HVAC system in the middle of summer. Definitely not ideal. The repair was going to be pricey so he opted for a new unit. A crew came out on a Saturday and did a very clean and efficient install. Highly recommend this company!!!

Very professional, work very neat and cleaned up and removed stuff. Very impressed with all of the staff and the company.
Our AC decided to quit during one of the hottest heatwaves in years. We called Scott's and someone was at the house to give us a quote in 30 min. From the moment they answered our first phone call through the install everyone was amazing, professional and provided a quality product and excellent service. Craig, Jose, Dexter were awesome! One of the new guys brought us a portable unit at 9:30 PM on a Friday so we could sleep. We missed his name, but shout out to him as well (he likes to give high fives). Thanks Scott and team for everything. We highly recommend!!!

For the past week I've worked with Craig on getting estimates for a new A/C unit, and he has been great at answering my questions and addressing any concerns. Very responsive and knowledgeable, straight shooter and direct! I didn't have to deal with any up-selling like working with a used car salesman (I experienced that with other bigger local A/C companies providing quotes). For these qualities alone I would recommend Scott's A/C, even though I will disclose that we ultimately went with another quote from a family referral of an A/C company. Had that family referral not been apart of our consideration, we would definitely choose and recommend Scott's for new A/C installs and service!
Dan in sales, outstanding jobgoing over equipment and helping us make what was the best decisions for us on purchasing new a/cinstall, plus scheduling the next day!Boris and Justin were excellent with communications while install and after! very clean, professional taking old out and installing new!ty
We can't thank Scott's enough. We came home to a air conditioner barely limping along. I called Scott's first thing in the morning and they had a technician out that day. Unfortunately our system could not be saved. The salesman Craig came out that day as well and quoted a new system. Since it was a Friday we could not get the system installed until Tuesday. Scott's provided us with a portable system which definitely helped during the grueling heat wave in Central Florida. Tuesday came, the installers showed up on time and did an awesome installation job. Cleaned everything up and went on their way. Everyone was pleasant, professional and great to work with! Thank You Scott's Heating & Cooling!

Always happy with their response time. Issue started last night causing our A/C unit to shut down. Made a call to Scott's Heating and Air in the morning and a tech was here by 10:45am. Tyrie, the tech, is awesome. He quickly took care of the problem and had us up and running in no time at all. He is knowledgeable and professional and did a great job.
Perfect company to do business with. Professional and courteous in all phases of project.

Excellent response and service. After 25 years of being serviced by a competitor I decided to change companies. AC was out and in need of replacement. Within 24 hours we had the sales rep here and new unit going in for a reasonable expense. No upselling, phony money savings, or timeshare presentations- just a new system without being targeted and pressured into pricey newer technology that will also become obsolete and non reparable every system cycle. I’m recommending to everyone looking for a new provider
