As homeowners are looking for ways to combat the ever-rising cost of energy, many are choosing to install a heat pump. However, if your home isn’t properly insulated and has significant air leakage, upgrading your heating and cooling system will only provide minimal savings.

At Hassler Heating & Air, we take a whole-home approach to improving the efficiency of homes throughout Marin, Contra Costa, and Alameda counties to ensure maximum savings. As a team of building scientists, we understand the importance of home performance upgrades like insulation and air sealing, not only to reduce your energy consumption and save money, but to improve your comfort and indoor air quality as well.

Why Insulation & Air Sealing Matter

Insulation and air sealing work together to create a barrier between your home’s living spaces and the outside elements. By preventing both heat transfer and airflow in and out of your home, these fundamental upgrades reduce energy loss and unnecessary wear and tear on your HVAC system. In fact, without a properly protected home, high-efficiency heating and cooling systems won’t reach their full potential, leaving you with comfort issues and high energy bills. If you don’t make insulation upgrades, you may even end up installing an oversized HVAC system, which will be more expensive than it needs to be and won’t perform optimally.

Hassler Heating & Air can help you optimize your home performance with our building envelope and air sealing services. In addition to their energy saving benefits, insulation and air sealing can:

Enhance your home comfort - The added layer or protections helps to eliminate drafty or stuffy rooms while making it easier for your home to maintain stable and consistent temperatures any time of the year.

Provide moisture control - Combining insulation and air sealing prevents moisture intrusion, which results in a reduced risk of mold growth, high humidity levels, and other risks.

Improve indoor air quality - By cutting off the point of entry for common pollutants like dust, pollen, and pests, you can create cleaner indoor air for your family so you can breathe easier.

Expert HVAC Installation with a Whole-Home Approach

At Hassler Heating & Air, we see your home as an interconnected system, with each component playing a crucial role in its performance. When you work with us to install a new HVAC system, we’ll make sure that it will seamlessly integrate with your home for optimal efficiency and comfort benefits. For example, making insulation and air sealing improvements before installing a new HVAC system can reduce the heating and cooling load requirements, meaning that it won’t require as much energy and you may even be able to install a smaller unit without sacrificing your comfort.

We offer a wide variety of high-efficiency heating and cooling systems, including:

Get Started with an Energy Assessment

The best way to determine where your home is losing energy through heat loss or air movement is with an energy assessment with our professional team. Using specialized tools and our building science knowledge, we’ll be able to accurately pinpoint where your home could benefit from insulation and air sealing upgrades. Our software allows us to model your home with the air sealing and insulation upgrades which typically allows us to downsize the capacity of your new equipment to improve equipment life, in-home comfort and reduced sound levels compared in and outside the home. From there, we’ll provide a customized plan of action for your specific needs and even help you find eligible rebates and incentives to make your home performance and HVAC upgrades more affordable.
