According to the Environmental Protection Agency, the air inside your home can be dirtier than the air outside. This is the result of a combination of normal, every day sources in your home such as pet dander, cleaning products, building materials, radon, tobacco smoke and even cooking residue. Vector Air Systems technicians can help determine which IAQ products are the right fit for your home. Poor air quality indoors can worsen health conditions such as allergies and asthma, and adversely affect children, the elderly, pregnant women or anyone with chronic respiratory issues. Your home's indoor air quality (IAQ) is made up of six different factors: particle allergens, volatile organic compounds, temperature, carbon dioxide, relative humidity and carbon monoxide. By improving the quality of the air inside your home, you can help keep dry skin and cracked wood furniture at bay, decrease the viruses and bacteria that can circulate throughout your home and enjoy more customized home comfort.

“It was our first experience with the A/C going out in the middle of an excessive heat warning.. 1st time this year that the temps reached 100 and of course my A/C went out.. Called a few companies and some service prices were just out of control and others told me tues?! Luckily George from Vector Air Conditioning was out to my house within an hour!! He diagnosed the problem and was able to fix the unit within an hour.. I never knew how much I appreciated my A/C working properly!! Thank You Vector A/C for saving us from this excessive heat!!!!! George was very friendly and got the job done!”
