Indoor air quality (IAQ) refers to the thermal conditions and concentration of pollutants inside a building. It affects the comfort, health, and productivity of the occupants in any home or office. Daily exposure to poor IAQ has significant effects over the long run, which is why professional installation is crucial to a healthy indoor environment.
At Positive Plumbing, Heating & Air Conditioning we offer a comprehensive range of indoor air quality solutions. If you own a residential or commercial property in Irvine, CA, we can help improve your indoor air quality.
We offer upfront pricing on all service repairs, and helping you provide a safe home or workplace is our priority.
Signs that you need professional indoor air quality solutions
Low indoor air quality is detrimental to health in many ways, especially when you are spending hours inside. Common symptoms of poor air quality include:
- Irritation of the nose, eyes, throat, and skin
- Asthma, shortness of breath, or other respiratory conditions
- Dizziness and headache
- Fatigue and low energy levels
- Nausea
- Sneezing and coughing
- Allergies
- Hypersensitivity
Linking these conditions to poor IAQ can be difficult, but there are several guidelines to consider before calling in our professionals. For example, you should schedule our indoor air quality assessment if you normally feel better after leaving a building or if the symptoms disappear on vacation or when you leave home for the weekend.
Factors that affect indoor air quality
Sources of indoor contaminants and pollutants include:
- Housekeeping activities, including the use of cleaning chemicals and dusting
- Occupant behavior, such as smoking
- Routine maintenance activities, like pest control and remodeling
- Emissions from office equipment
- Dust in the HVAC ductwork
- Insufficient distribution of clean air via the ventilation system
- Microbial growth in HVAC filters and ducts
- The inflow of contaminated outdoor air
If you notice poor indoor air quality and think your cooling system may be to blame, be sure to call our professionals to schedule an A/C maintenance service.

UV Light Sanitizers
Contaminants indoors lead to sneezing, nasal and eye irritation, among other problems. Our team at Positive Plumbing, Heating & Air Conditioning can eliminate these issues within your home or workplace with air-cleaning UV lights installation in Irvine, CA.
We have whole-home UV air sanitizers that work with your central HVAC unit as well as efficient standalone systems. The best system for you will depend on your budget, air cleanliness goals, and other preferences.
How do UV air sanitizers work?
UV lights for air cleaning are powerful—they eliminate over 90% of the bacteria, viruses, and other harmful microorganisms in the atmosphere with your home or business. The system uses ultraviolet light, specifically UVC light, to destroy contaminants by damaging their molecular structure (germs with compromised molecular structures can’t perform the processes needed to survive and spread).
Our team can provide you with UV lights that kill mold spores, allergens, and other organisms that negatively affect your indoor air quality. The system is also quiet enough to avoid distractions within your space and requires minimal maintenance, ensuring you can enjoy it for long periods without repair issues.
On the downside, UV air sanitizers are not as effective as other air cleaners for eliminating dust, pet dander, and inorganic pollutants. If you want the best of both products, we advise pairing a sanitizer with an air purifier for optimal air cleanliness in your home or office.
UV Lights in Irvine
If you are not sure whether you need UV lights in Irvine, ask yourself these questions:
- Do the people in this home or office frequently suffer from allergies?
- Are flu or other respiratory infections common in this building?

If you answered yes to any of these questions, you would benefit greatly from our UV light installation services.
Our experienced professionals only install UV air cleaners from reputable brands, ensuring lasting and satisfying results. The products we supply are powerful enough to eradicate over 50% of indoor pollutants within an hour of switching on the unit.

The best air purification in Irvine
After inspecting your property, our technicians will recommend a personalized solution that satisfies your unique needs and fits your budget. You can choose from a whole-house air purification system that works with your central HVAC unit or a less expensive standalone portable air cleaning system.
Our professionals pride themselves on the quality of the installation, using only products from leading brands that:
- Kill and filter bacteria, allergens, other contaminants
- Improve air circulation within your space
Air Purifier or Sanitizer: Which Option Is Better?
Both air purifiers and sanitizers improve indoor air quality, but the processes are vastly different. For example, some air sanitizers use ultraviolet (UV) light to kill viruses, bacteria, and allergens. The system is so effective that it can kill 50% of airborne bacteria within an hour of turning on the device.
Other sanitizers use germicidal irradiation to clean the air and destroy pollutants. While air sanitizer systems kill airborne germs and other harmful microorganisms, these systems are not as efficient at eliminating dust, pet dander, and similar pollutants as an air purifier.
Air purifiers rely on various types of filters to extract and trap smoke, dirt, odors, and other pollutants and remove these contaminants from the indoor air. The contaminants remain trapped in the filter until you clean or replace it.
An air purifier may use a carbon, HEPA, or ionic filter, or a combination of these choices.
Since air purifiers aren’t as effective at eliminating germs, we recommend installing a unit alongside an air sanitizer for the best indoor air quality.
