Indoor Air Quality

Orange County Indoor Air Quality

High Quality Products for Healthier Air

Indoor air quality in homes and commercial buildings has a significant impact on health, comfort, productivity, sleep patterns, and even the integrity of the structure. Unfortunately, the indoor air is often up to five times dirtier than outside, according to the EPA. John StevensonPlumbing, Heating & Air offers solutions to improve indoor air quality in Orange County.

Our Orange County indoor air quality experts can assess your air quality, listen to your concerns, and provide the information you need about various products to help you choose the right equipment for your residential or commercial property. Our factory trained, NATE certified technicians are well-qualified to handle the installation.

The Effects of Poor Air Quality

The indoor air quality in residential and commercial buildings can be contaminated with a wide range of particulates and pollutants. This can result in triggering allergy and asthma symptoms, spread illness, and cause other respiratory health problems.

Indoor air may be contaminated by:

  • Dust
  • Allergens, such as pollen and pet dander
  • Household or industrial chemicals
  • Tobacco smoke
  • Pesticides
  • Radon
  • Formaldehyde
  • Mold spores
  • Volatile organic compounds (VOCs)
  • Biological contaminants

The problem is intensified by the airtight nature of modern homes and commercial buildings. Better insulation, windows, and doors have created a building envelope that keeps the polluted air trapped inside. While this is excellent for the efficiency of heating and air conditioning systems, the lack of air exchange from indoors to outside has made indoor air quality even worse.

Methods for Improving Air Quality

A variety of equipment is available for improving indoor air quality in Orange County. The best solution for your air depends on the quality of the air and the specific contaminants that need to be targeted.

We install equipment to improve air quality, such as:

  • Humidifiers – When the humidity is too low, it can cause a variety of problems, such as drying out your skin and hair, creating sinus pressure and dryness, causing wood flooring or furnishings to crack or split, and reducing the efficiency of heating equipment. Installing a humidifier can help you keep the humidity at optimal levels for health and comfort.
  • Dehumidifiers – High humidity levels create an entirely different set of problems. A humid house is uncomfortable and the moisture can result in additional problems, such as mold growth and insect infestations. Installing a dehumidifier helps lower the humidity levels to prevent mold growth, create a more comfortable indoor environment, and the lower humidity allows you to raise the temperature which saves money.
  • Air purifiers – An air purifier can filter out particulates in the air, which helps to reduce asthma and allergy symptoms, eliminate harmful chemicals, and leave the air fresher and smelling better. You may find that you are breathing easier and sleeping better when the air is cleaner.
  • Ventilators – The V in HVAC stands for ventilation. Properly ventilated buildings have fewer impurities and harmful pollutants in the air. Ventilators help reduce moisture, improves energy efficiency, and creates a safe and healthy indoor atmosphere for your family or employees.
  • UV lamps – Ultraviolet lights are effective for destroying airborne organisms, such as bacteria and mold. The lamps are installed in the HVAC system and purify the air as it passes through.
  • Duct Cleaning – Ducts can accumulate a number of contaminants that can impact the quality of your indoor air, including dust, mold, smoke, pet dander, and even bacteria. Regular duct cleaning can keep your air fresher, not to mention its great for boosting the efficiency of your HVAC system!

Frequently Asked Questions
  • Should I replace or repair my AC unit?

    Many customers ask if they should repair a broken air conditioning unit versus a full replacement. Often, a well-maintained and newer AC unit will be able to be repaired depending on the issue. If it is a part under warranty, replacement of the part is a simple fix. However, if the AC is more than 10 years old, has not been regularly serviced, or is in need of a major repair, replacement is the best option. Our team will provide all available options for homeowners to consider.

  • What's a Pre-Installation Evaluation? Does My New A/C Need One?

    In short, yes. A first step is conducting an energy audit to determine the energy load for your home. Calculating the load tells the experts at John Stevenson Plumbing, Heating & Air how much heat your house gains throughout the day & what size air conditioner will work best to keep it cool. This is critical as most A/C installation issues stem from an improperly-sized air conditioning unit.

  • Is Your Home's Ductwork & Design Able to Handle a New A/C System?

    Often your old, existing ducts can’t handle the airflow of a newly installed air conditioner. Any upgrades to accommodate a new system will likely increase the cost to install an A/C unit, but will ultimately help you avoid costly, high energy bills & hot rooms in the future.

  • What Type of Central A/C Unit Should I Install?

    Here’s where the load calculation comes into play, as you want to pick the right size A/C unit to install – either too big or too small of an A/C unit can lead to costly repair or replacement down the road. Call the HVAC professionals at John Stevenson Plumbing, Heating & Air, they’ll know which A/C unit is perfect to install in your home at the lowest price.
