Hassler provides a wide range of HVAC and home performance services, from maintenance, repairs and complete system replacements to energy efficiency upgrades such as air draft sealing, crawlspace moisture treatment systems and insulation installation. Hassler is a participating contractor in PG&E’s Energy Upgrade California Advanced Home Upgrade program, which offers homeowners up to $6,500 rebates for home efficiency improvements. Hassler takes a scientific, “whole house” approach to improve its customers’ indoor health, energy efficiency and home comfort.
CFO Tim Hassler says Hassler’s ability to act as both a full-service HVAC contractor and a home performance company has been a crucial aspect of its success. “It’s rare to find a contractor that handles both sides. Our clients call us and refer us to others because they know we’re passionate about helping people optimize their energy efficiency and improve their home comfort and health. We offer the highest value in the industry because we’re able to adapt our services to each unique situation.”
Hassler’s experienced installation and service technicians are continually trained on how to educate clients about their homes. “Many homes in the Bay Area are not as healthy as they should be,” says Mr. Hassler. “One common problem is poor attic and crawlspace ventilation, which can be easily fixed or mitigated in most cases with proper diagnoses and implementation.”
“Our goal is to strive to make an impact on our clients’ daily lives by improving their home comfort, energy efficiency and indoor health while helping the State of California meet its energy reduction goals one home at a time.”
