Our Indoor Air Quality Services

The A+ Derr team offers various indoor air quality services to accommodate any family’s needs. We proudly install and service:

  • Air purifiers: These remove odorous and harmful gases such as cooking odors, bacteria, and viruses from the air, so you’re left with healthier, fresher air year-round.
  • High Efficiency Air Cleaners: Air scrubbers remove dirt, dander, pollen, bacteria, and more from your air while purifying and disinfecting, leaving you with distinctly cleaner, healthier air free of harmful pollutants.
  • Humidifiers: Humidifiers help maintain a healthy humidity level, preventing problems such as dry skin, nose and eye irritation, and higher chances of getting sick. 
  • Dehumidifiers: Dehumidifiers also help maintain ideal humidity by keeping the air from getting too humid, leading to mold, mildew growth, and overall discomfort. Dehumidifiers are also crucial for keeping basements dry.
  • Duct cleaning: Dust, allergens, and debris in your home’s ductwork can negatively affect your indoor air quality. Duct cleaning solutions from A+ Derr can improve indoor air quality, ensuring that you and your family breathe easier.

How to Tell if You Have Poor Indoor Air Quality

You may worry about whether your town’s air is polluted, but you should know that the air in your home can be up to five times more polluted than outdoor air.

Here’s how to tell if you have poor indoor air quality:

  • You wake up with a dry throat every morning: Frequent dry or itchy eyes, dry throat, nose bleeds, and sneezing are all signs that your air is too dry. Dry air also increases your risk of catching airborne illnesses.
  • The air feels muggy or sticky: If it always feels humid and sticky in your house, you likely need a whole-home dehumidifier. Aside from discomfort, excess humidity also encourages mold and mildew growth.
  • Someone has a respiratory condition: If someone in your home has a respiratory condition, their symptoms are likely worse in a house with polluted air. 
  • Your air never smells fresh: Cooking, pet odors, cleaning chemicals, mold and mildew, smoking, and more can cause unpleasant and unhealthy odors that can’t be removed by cleaning or opening a window.

Indoor Air Quality FAQs

Here are some things you can do regularly to keep your home’s air fresher and healthier year-round: 

  • Clean or replace the filter in your HVAC system at least every three months, and more often if you have pets or someone smokes in the house.
  • When the weather permits, open windows to circulate fresh air.
  • Always use the vent fan over your stove when cooking to reduce humidity from steam.
  • Vacuum once a week if you have two or more pets that shed fur. 

Indoor air is polluted by particles, germs, and chemicals. All three can cause respiratory problems, fatigue, and an increased risk of getting sick. They can also reduce the service life of your HVAC equipment and lead to more frequent repair needs.

The need for indoor air quality systems is obvious, such as a dehumidifier if your air is too humid or you notice mold or mildew growth. Other issues don’t have an obvious solution, so our experts can assess your home’s air and make a professional recommendation.

Jake came and did my spring service yesterday. Their service is very professional, they are always out to get the best deals for anything I may need. I purchased new units from them a couple years ago, and the savings has been so noticeable.
