At JW East Mechanical, we are committed to enhancing the indoor air quality (IAQ) for our clients, ensuring they breathe cleaner, healthier air. Recently, we undertook a project to assess and improve the air quality in a Houston home, focusing on two critical areas—the primary bedroom and family room.
Understanding the Need for Air Quality Improvement
Our client wanted to improve the air quality in their home to benefit their overall health and comfort. One family member, who uses a CPAP machine at night, had expressed concerns about the air quality in the bedroom. And because the family spends a large amount of time in the family room in the evenings, it was the second room chosen.
The Testing Process: Particle Count and Mass Concentration
To address these concerns, we performed a detailed assessment using two specialized instruments:
- Primary Bedroom Testing: We placed a large particle counter on the bed in the primary bedroom. This location was chosen because it is where the CPAP user spends several hours each night. The focus was on measuring both the particle count and mass concentration over a 30-minute period. This duration was enough to gather representative data for an accurate air quality report.
- Family Room Testing: In the family room, a small meter equipped with a high-limit alarm was used. This device ran concurrently for 30 minutes, capturing data on particulate matter. The high-limit alarm helped us identify any significant spikes in particle levels during the testing time period.
Analyzing the Results
Once the testing was complete, we were able to collect the data and created a comprehensive air quality report. This report provided insights into the levels of particulates present in both rooms, necessary for developing an effective air quality management strategy. Also, the report was shared with the client’s pulmonary physician to help them understand the potential impact of the home environment on their respiratory condition.
Recommendations for Improving Air Quality
Based on the findings of our tests, we proposed several measures to reduce the concentration of particulates in the home:
- Enhanced Filtration Systems: Installing advanced HVAC filters to trap smaller particles that standard filters might miss.
- Air Purification: Adding air purifiers in key areas to actively reduce contaminants and improve air freshness.
- Regular Maintenance: Encouraging routine HVAC maintenance to ensure systems are operating efficiently and effectively.
- Ventilation Improvements: Suggesting enhancements to the home’s ventilation, such as adding exhaust fans or using air exchangers, to allow for better air circulation.
At JW East Mechanical, our goal is to ensure that the systems we install and maintain contribute to a healthier living environment. This case study highlights our commitment to thorough testing and tailored recommendations that meet the unique needs of every client.

We often think of air pollution as an outdoor problem, but the air inside our homes can be just as concerning. In fact, the air we breathe indoors can significantly impact our health, especially when it comes to tiny particles known as PM2.5 and PM10. Let’s dive into what these elements mean and why they are important to the health of your family.
PM2.5 – The Invisible Threat
PM2.5 refers to fine particles that are 2.5 micrometers or smaller. These particles are so tiny that they can penetrate deep into our lungs and even enter our bloodstream. Here is how to interpret PM2.5 readings:
- Excellent: 0-5 ug/m3
- Good/Normal: 5-12 ug/m3
- Moderate: 12-35 ug/m3
- Poor: 35+ ug/m3
PM10 – The Visible Culprits
PM10 particles are larger, measuring up to 10 micrometers. These are tiny particles you might see floating in a beam of light, like dust or pollen. PM10 particles are classified as:
- Good: <50 ug/m3
- Moderate: 50-100 ug/m3
- High: 100+ ug/m3
What your AIr Quality results mean
Understanding your air quality readings is crucial for maintaining a healthy home environment. If your PM2.5 levels are consistently under 15, congratulations – your air quality is great! However, if you are seeing readings between 20-30+ PM2.5 for extended periods, your air quality could use some improvement. More concerning are readings of 40-100+ PM2.5, which likely indicate an active source of pollution that needs to be identified and corrected immediately. These higher levels can pose significant health risks and should not be ignored. Because prolonged exposure of PM2.5 can lead to serious health issues:
Heart and Blood Vessel Problems
- Increased risk of heart attack and stroke
- High blood pressure
- Hardening of the arteries
- Irregular heart rhythms
- Higher risk of heart failure
Lung and Breathing Issues
- Reduced lung function
- Worsened asthma and COPD
- Increased chronic bronchitis
- Higher susceptibility to respiratory infections
- Elevated lung cancer risk – even for non-smokers
Brain and Nervous System Effects
- Accelerated cognitive decline
- Increased risk of dementia and alzheimer’s
- Memory and concentration problems
Metabolic Impacts
- Higher risk of type 3 diabetes
- Worsened blood sugar control
- Increased inflammation
Cancer Risks
- Stronger link to lung cancer
- Possible connection to bladder and other cancers with long-term exposure
It’s important to note that PM2.5 is classified as a Group 1 carcinogen by the International Agency for Research on Cancer (part of the World Health Organization) – the same classification as tobacco smoke.
Protecting your Family and Pets
The elderly, young children, and pets are particularly vulnerable to the effects of poor indoor air quality. By not actively treating the air inside your home, you are leaving the task of filtering these harmful particles to your family’s lungs.
“We take indoor air quality very seriously at JW East. The main thing to remember here is that we need to be aware of the air that we breathe,” said Jim East, President of JW East Mechanical. “If you are not filtering your indoor air, your lungs will have to do all the work and that causes negative side effects. Your air duct system should be considered the respiratory system of the home, not just a way to move air. And like our lungs, the respiratory system in our home needs to be properly taken care of.”
Take Action for Cleaner Air
- Regularly maintain and clean your HVAC system
- Use high-quality air filters and change them as recommended
- Consider adding air purifiers to key areas of your home
- Ventilate your home regularly, especially when cooking or using cleaning products
- Keep indoor plants that can help purify your indoor air naturally
Remember, the air you breathe at home directly impacts your and your family’s health. By understanding and improving your indoor air quality, you are taking a big step towards a healthier and happier home. And don’t forget that we are here to help! Call us today to schedule an indoor air quality inspection. We will find the perfect solution for your home that fits your budget.

On the jobsite, we’re often asked about ideal thermostat settings. That is why we are dedicating this blog post to the thermostat, focusing on minimum cooling settings and the crucial role of dew point in your home’s air quality and your overall comfort.
Understanding Dew Point and Its Impact
Dew point is a critical factor in Houston’s humid climate. It’s defined as “the temperature at which air must be cooled to reach saturation and for condensation to form.” For optimal indoor air quality and comfort, the ideal dew point in your home should be between 40 and 60 degrees.
Minimum Cooling Settings: A Delicate Balance
- At-Home Settings: Never set your thermostat below the outdoor dew point when you’re at home. Why? When indoor air temperature drops below the dew point, it can cause your home’s structure to “sweat,” increasing condensation and potentially leading to microbial growth.
- Away Settings: When you’re away, don’t set the thermostat more than 10% above the outdoor dew point.
Real-World Example: In August 2025, Houston’s average dew point was 73.7 degrees. Based on this:
- At-home setting should not be below 73 degrees
- Away setting should not be higher than 80 degrees
Summer vs. Winter
Ever wonder why you’re comfortable at 70 degrees in summer but feel chilly at the same temperature in winter? The answer lies in humidity levels. In winter, with the furnace running, the air is drier, making a slightly higher temperature feel more comfortable.
The Importance of Proper HVAC System Design
If your system struggles to control latent heat removal (the process of removing water vapor) between these set points, it may need to be checked for proper sizing. In some cases, adding a whole-house dehumidifier might be necessary.
In our mostly swamp-like conditions, controlling dew point should be a fundamental aspect of every HVAC system design. It’s crucial for both comfort and indoor air quality, as it helps prevent the growth of molds and bacteria.
Understanding the relationship between temperature, humidity, and dew point is key to maintaining a comfortable and healthy home environment in Houston. At JW East Mechanical, we’re committed to helping you achieve the perfect balance in your home’s climate control.

If you were to ask Jim East, the owner of JW East Mechanical, what issue homeowners should be most concerned with when it comes to their HVAC system, he will tell you indoor air quality. While the HVAC system is primarily known for regulating temperature, its role in maintaining clean, breathable air is equally critical. Poor indoor air quality can lead to allergies, respiratory issues, and general discomfort, especially in Houston, where humidity promotes mold growth and allergens thrive. Prioritizing indoor air quality within your HVAC system ensures that the air you breathe is not only temperature-controlled but also free from pollutants, mold, and excess moisture—making it the most essential aspect of your HVAC setup for health.
“In recent years, I have spent a lot of my off season time in workshops, webinars, and hands-on classes on the subject of creating a “Healthy Home” indoor environment for my clients,” said East. “This takes the HVAC system to another level of comfort, and creates a healthier environment to live in and raise a family. Treating air is not limited to just removing or adding moisture or heating and cooling it. There is so much more. Treating the air should also include treating for gases, odors, microbials, and particles. In an enclosed environment, if you do not take these under consideration, that means that human lungs become the only device keeping them from entering the body. The lungs become filters and will break down at some point having to filter out extra contaminants from your system. We cannot control the air outside our home, but we can inside.”
Because of East’s passion for indoor air quality, he was recently invited to join IAQA, the Indoor Air Quality Association, which supports professionals worldwide in creating healthier indoor environments.
According to IAQA, “Our multi-disciplinary members include IAQ inspectors, consultants, remediators, contractors, facility maintenance professionals, researchers, educators, industry vendors, school officials, and government representatives. These experts identify and help solve conditions leading to compromised air quality such as mold, moisture, ventilation, asbestos, lead paint, formaldehyde, water damage, and air contaminants.”
East was recommended by another HVAC contractor who came to him for advice on solving an indoor air quality issue.
“A couple of my contractor peers asked me to help them with problem solving a client’s issue about their contaminated indoor air quality,” said East. “I was able to recommend step by step instructions on how to correct the issues. Once they performed the plan I laid out for them, it corrected the problem. These peers were the ones that recommended me to this association, which I was extremely happy to accept.”
If your home is experiencing any issues with indoor air quality, please call the experts at JW East Mechanical. We will not stop until the issue is resolved.
