HighSeer Energy exists for one reason: to make San Diego homes cost dramatically less to heat and cool. For ten years we've specialized in high-efficiency upgrades, heat pump conversions, and the energy audits and rebate work that make them pay off.

The Rebates Alone Are Worth the Call
SDG&E, the state of California, and federal programs offer thousands in rebates and tax credits on high-efficiency systems and heat pumps — but the paperwork stops most homeowners cold. We find an average of $3,200 per home and handle every form for you.
Stack the rebates with up to 40% lower bills and financing, and a high-efficiency upgrade often costs far less than people expect — and pays itself back faster than they think.

Energy Efficiency FAQs
How much can a high-efficiency upgrade really save?
Often a lot — replacing an old low-SEER system with a high-SEER2 unit or heat pump, plus sealing ducts, commonly cuts cooling bills up to 40%. The exact savings depend on your home and current system, which is what our free energy audit measures precisely.
What rebates are available?
SDG&E, California state programs, and federal tax credits all offer incentives on qualifying high-efficiency systems and heat pumps — we find an average of $3,200 per home. The catch is the paperwork, which we handle entirely for you.
What is a home energy audit?
It's a data-driven assessment of where your home wastes energy — leaky ducts, an oversized or aging system, envelope issues. We use real instruments, not guesswork, so the upgrade we recommend targets your actual waste and delivers real savings.
Should I convert to a heat pump?
In San Diego's mild climate, very often yes. Replacing separate gas heating and AC with one high-efficiency heat pump can dramatically cut energy use and qualifies for the biggest rebates. We'll show you the payback math for your specific home.
Will you show me the payback before I commit?
Always. We show you the projected savings, the rebates, the financing, and the honest payback period up front — before you spend a dime. Efficiency is a numbers game, and we put the numbers in front of you.
Do you offer financing?
Yes. Between rebates, financing, and up to 40% lower bills, a high-efficiency upgrade often costs far less out of pocket than homeowners expect — and starts paying itself back right away.
