Central Islip Indoor Air Quality Services
Suffolk Counties' Choice for Indoor Air Solutions
The quality of your indoor air may not be something you think about often, and yet it is extremely important. This is especially true if you suffer from allergies or asthma. There are numerous contaminants that may be floating around your home, including dirt, dander, pollen, dust, bacteria, viruses, mold, mildew, and chemicals. Such pollutants can not only trigger allergic and asthmatic reactions but can also lead to itchy eyes, runny noses, sore throats, stuffiness, headaches, dizziness, or even serious respiratory issues.

Whole-Home Air Cleaners
Of all the types of air purification systems on the market today, whole-home air cleaners provide the most comprehensive solution. This type of air cleaner is installed as part of your home’s central HVAC system. Every time your furnace or air conditioner runs, the whole-home air cleaner works to remove potentially harmful contaminants from your air. After the air is cleaned, it is then distributed to every room of your home through your HVAC system’s ductwork. These units are simple to maintain and require significantly less attention than portable units or standard filters. Call GMG HVAC Inc. to turn your HVAC system into a powerful whole-home air cleaner.
Duct Cleaning Services
Although duct cleaning is an essential aspect of maintaining good indoor air quality, it can often be overlooked. Over time, dust, bacteria, mold, and other indoor pollutants can accumulate in your ductwork. If your home’s ductwork has never been cleaned, it may even contain debris leftover from when it was built. Such buildup not only impacts the quality of your indoor air but also decreases an HVAC system’s efficiency and longevity. Cleaning your air ducts is a great way to ensure the health, safety, and well-being of you, your family, and your HVAC equipment. Get in touch with our expert technicians now to get your duct cleaning underway.
Air Filter Changing
GMG HVAC Inc. has helped hundreds of homeowners replace air filters to improve both air quality and overall airflow. As a filter gets full, it loses its ability to trap harmful contaminants that are in your indoor air. A dirty air filter will also make your heating and cooling system work harder, which leads to higher energy bills and premature replacement. Our Central Islip indoor air quality specialists can help you change your air filters quickly and effectively.
