While summer is nearing its end, cooling season isn’t quite over just yet. Many homeowners are still struggling to stay comfortable with the high humidity levels we’ve been seeing in Marin, Contra Costa, and Alameda counties recently. While your humid home is certainly an inconvenience, it can also cause problems for your indoor air quality as well. 

The EPA recommends that indoor humidity levels stay within a 30-50% range to keep your home protected from mold growth and damage. Luckily, the team at Hassler can provide several solutions to reducing your indoor humidity level, improving your air quality, and keeping you comfortable so you can enjoy the last days of summer. 

Start With a Home Energy Audit

When you’re experiencing comfort issues in your home, it’s important to understand exactly what’s causing them—and an Full energy assessment from Hassler can do just that! Also referred to as an energy audit, these diagnostic tests can help pinpoint why your home is so humid and stuffy, whether it’s a malfunctioning air conditioner, an under-insulated attic, a moist crawlspace, or inadequate ventilation.

Using specialized tools like an infrared camera and blower door test we’ll analyze your home’s insulation and discover any significant air leaks that are allowing moisture to infiltrate your living spaces. 

A home energy audit can be a valuable tool in identifying and addressing high humidity issues in a home. Excessive humidity can lead to various problems, including discomfort, mold growth, and increased energy costs. Here are some examples of how a home energy audit can help solve the problem of high humidity in a home:

  1. Identification of Moisture Sources: During a home energy audit, a professional auditor will thoroughly inspect your home to identify potential sources of moisture. This can include leaky pipes, roof leaks, improper ventilation, or water infiltration through the foundation. Identifying and addressing these sources can help reduce indoor humidity.

  2. Assessment of Insulation and Air Sealing: Poor insulation and inadequate air sealing can contribute to humidity problems. An energy auditor will evaluate your home's insulation levels and check for air leaks that may allow warm, moist outdoor air to infiltrate your home. Addressing insulation and air sealing issues can help maintain consistent indoor humidity levels.

  3. HVAC System Evaluation: The heating, ventilation, and air conditioning (HVAC) system plays a crucial role in controlling indoor humidity. An energy audit will assess the performance of your HVAC system, including the sizing and efficiency of your air conditioner and dehumidification capabilities. If your system is improperly sized or inefficient, it can lead to humidity problems.

  4. Ventilation Assessment: Proper ventilation is essential for maintaining healthy indoor air quality and controlling humidity. An energy auditor will check the functionality of exhaust fans in areas like the kitchen and bathroom and assess the effectiveness of your home's overall ventilation strategy. Improving ventilation can help remove excess moisture from the air.

  5. Recommendations for Improvements: Based on the findings of the energy audit, you will receive recommendations for improvements. These may include sealing air leaks, upgrading insulation, repairing leaks, installing a dehumidification system, or upgrading your HVAC equipment to better control humidity.
