Home Performance Upgrades in Oakland

California’s energy costs are surging with no end or slowdown in sight. That means the cost of living is constantly going up, especially for those whose homes are older or are getting gradually less and less efficient. As HVAC equipment ages, it slowly begins to lose performance, and that means it consumes more energy to provide the same level of comfort it once did. Combined with other parts of your home’s HVAC system and air control wearing out, you may be paying substantially more for your heating and cooling than you need to.

This is where our home performance experts at Hassler Heating and Air Conditioning can help. We offer full energy assessments to see where you’re losing the most energy and determine what upgrades will have the greatest impact. If you want to improve your home comfort and efficiency but don’t know where to begin, our expert team can make recommendations tailored to your goals and to where your home’s greatest weaknesses are. We are also local experts on improving indoor air quality, meaning we can help you remove airborne particles and contaminants from the air you breathe so that you can enjoy a cleaner, healthier home. 

Take Advantage of PACE Financing

We believe that investing in your HVAC system and your home’s energy efficiency is a great decision for all Californians, and we believe that this investment should be affordable, no matter your budget. We are proud to offer great financing, rebates, and other incentives, including Property Assessed Clean Energy (PACE) financing. This option allows our local government to provide efficiency-centric home improvement financing through incremental increases in property taxes. This program is an excellent option for homeowners who want to enhance their home’s performance but don’t have the upfront cash to do so. Our team can work with you to help you better understand this program and determine if it's an option the services you need!
