Houston Homes: Cheap AC Inflaming Senior Lungs?
By Franklin Everett ShawThe air in Houston can be thick enough to cut with a knife, especially during the summer. But what if the very system designed to offer relief – your air conditioner – is actually making things worse, particularly for our senior citizens? It’s a harsh reality that many older, poorly maintained AC units are silent culprits, exacerbating respiratory issues and diminishing the quality of life for those most vulnerable.
This isn’t just about comfort; it’s about health and well-being. Let’s dive into how your aging AC could be harming you, and, more importantly, what you can do about it, right here in Houston.
Older AC units, especially those on a fixed income budget, often suffer from neglect. This neglect translates directly into poor air quality. The primary issue? Inadequate filtration.
Most older units come equipped with basic fiberglass filters. These filters are designed to catch large debris like dust bunnies, but they are woefully ineffective at trapping smaller particles like pollen, mold spores, and pet dander – all common allergens in Houston. These microscopic irritants circulate freely, triggering asthma, allergies, and other respiratory problems.
Think about the oak pollen that blankets everything in the spring, or the mold that thrives in Houston’s humid climate. These allergens are easily drawn into your AC system and then redistributed throughout your home.
Furthermore, a dirty AC unit is a breeding ground for mold and bacteria. The cool, damp environment inside the unit provides the perfect conditions for these organisms to flourish. These contaminants are then blown into your living space, further compromising air quality.
Regular maintenance is crucial, but often overlooked. A neglected AC unit not only performs poorly but also consumes more energy, leading to higher electricity bills. This is a double whammy for seniors on a fixed income.
So, what can you do to combat these issues and breathe easier? The good news is that there are several actionable steps you can take, ranging from simple DIY solutions to more comprehensive professional services.
First, let’s talk about filter upgrades. Ditch the cheap fiberglass filters and invest in higher-quality pleated filters. Look for filters with a MERV (Minimum Efficiency Reporting Value) rating of 8 or higher. These filters are significantly better at trapping smaller particles.
For example, a MERV 11 filter will capture a much higher percentage of pollen, mold spores, and pet dander than a MERV 4 filter. While higher MERV ratings offer better filtration, they can also restrict airflow, potentially straining your AC unit. A MERV 8 or 11 is generally a good balance between filtration and airflow for older units.
Changing your filter regularly is just as important as using a good one. In Houston’s dusty environment, you should aim to change your filter every 30-60 days, or even more frequently if you have pets or allergies. Set a reminder on your phone or calendar to ensure you don’t forget.
Next, consider a DIY coil cleaning. Over time, the evaporator and condenser coils in your AC unit can become coated with dust and grime, reducing their efficiency and contributing to poor air quality. You can clean these coils yourself using a fin comb and a specialized coil cleaner, available at most hardware stores.
Be sure to turn off the power to your AC unit before attempting any cleaning. Follow the instructions on the coil cleaner carefully, and wear gloves and eye protection. This simple task can significantly improve your AC’s performance and air quality.
However, DIY solutions have their limits. For a truly deep clean and inspection, consider hiring a professional AC servicing company. A qualified technician can thoroughly clean the coils, check for leaks, and ensure that all components are functioning properly.
Many local Houston companies offer affordable servicing options, and some even provide discounts for seniors. Don’t hesitate to call around and compare prices. A well-maintained AC unit will not only improve your air quality but also save you money on energy bills in the long run.
Now, let’s talk about AC replacement. While it may seem like a daunting expense, replacing an old, inefficient AC unit with a newer, energy-efficient model can be a worthwhile investment, especially for seniors.
Newer AC units are not only more energy-efficient but also come equipped with advanced filtration systems. Many models feature HEPA filters, which are capable of trapping even the smallest particles, including viruses and bacteria.
Furthermore, there are several senior-specific energy efficiency programs in Houston that can help offset the cost of AC replacement. CenterPoint Energy, for example, offers rebates and incentives for upgrading to energy-efficient appliances.
The City of Houston also has programs that provide assistance to low-income residents, including seniors, for home repairs and energy efficiency upgrades. Contact the city’s Housing and Community Development Department to learn more about these programs.
When choosing a new AC unit, consider models that are specifically designed for the Houston climate. Look for units with a high SEER (Seasonal Energy Efficiency Ratio) rating, which indicates their energy efficiency. A SEER rating of 14 or higher is generally recommended for Houston’s hot and humid climate.
Also, consider models with features like variable-speed compressors and smart thermostats, which can further improve energy efficiency and comfort. Some popular and reliable brands for Houston include Trane, Carrier, and Lennox.
Specifically, for Houston allergens, consider units with enhanced filtration systems designed to capture common irritants like oak pollen, ragweed, and mold spores. Look for models with allergen-reduction filters or UV-C light technology, which can kill mold and bacteria.
One common mistake developers face is neglecting the ductwork. Even with a brand new AC unit, leaky or dirty ductwork can negate the benefits of improved filtration. Have your ductwork inspected and sealed to ensure that clean air is being delivered to all areas of your home.
Another pitfall is oversizing the AC unit. A unit that is too large will cool your home too quickly, leading to short cycling and poor dehumidification. This can actually increase humidity levels and create a more favorable environment for mold growth. Consult with a qualified HVAC technician to determine the appropriate size AC unit for your home.
Finally, remember that maintaining good indoor air quality is a holistic approach. In addition to addressing your AC system, consider other factors like ventilation, humidity control, and regular cleaning.
Open windows and doors periodically to ventilate your home, especially during cooler hours. Use dehumidifiers to control humidity levels, particularly in bathrooms and kitchens. And vacuum regularly with a HEPA filter vacuum cleaner to remove dust and allergens from your carpets and upholstery.
Taking these steps can significantly improve your indoor air quality and create a healthier living environment for you and your loved ones. Don’t let your aging AC unit compromise your health and well-being. Take action today to breathe easier and enjoy a more comfortable life in Houston.
