San Diego born and raised. Decades of experience. Family owned. At Legacy Home Energy, we’re committed to delivering exceptional service to the San Diego community and beyond.
About Us
Background of Legacy
Legacy Home Energy was born out of decades of experience helping San Diego homeowners with heating, air conditioning, energy solutions and beyond.
Cody Mauzy started the company, taking everything he learned from years in the industry working for his family’s business, and doing it his own way with a special touch — more personal, more honest, and more focused on the long-term needs of local families.
At Legacy, we are family-owned, San Diego born and raised, and our local connection to the community drives how we treat our customers and stand behind our work.
Our Company Values
We value transparency, integrity, and craftsmanship. Our goal is to give San Diego homeowners peace of mind— not just during the initial installation, but for years to come. We do not cut corners and we only recommend what we’d do in our own homes.
What Sets Legacy Apart
When it comes to choosing the right contractor for your home improvement energy upgrades, you want to be sure your contractor is experienced, well-versed, and provides excellent customer service. At Legacy, we do it all – and better. When you partner with us, you reap the benefits of a one-stop-shop for energy upgrades handling everything soup-to-nuts as well as:
- Local, family-owned roots (not a corporate chain)
- One-on-one customer relationships from start to finish
- Deep experience with HVAC, solar, home batteries and roofing— a rare combo in the market
- High-quality installs backed by strong warranties and personal accountability
OUR GUARANTEES
At Legacy, we understand that home improvement upgrades are an investment. That’s why we offer the following guarantees to ease your mind when you partner with us
Extended Workmanship Guarantee
Home energy improvement upgrades are an investment. We are confident our products are installed by certified experts and built to last. With our Extended Workmanship Guarantee, we offer long-term coverage for any installation and construction defects.
Satisfaction Guarantee
At Legacy, your satisfaction is our commitment. We guarantee you’ll be 100% satisfied with our products. If for any reason you are not satisfied, we will remove the products and refund your money.
Prompt Service Guarantee
When you need service on your heating, air conditioning or solar system, you need a dependable contractor who can deliver swift service. We promise prompt service within 24 hours. If we fail to deliver on our promise, we’ll waive your service fee.
Total Replacement Guarantee
Our high quality products are built to last. We are confident you will enjoy your system for years to come. In the rare chance you receive a faulty product with multiple failures in the initial years of installation, we will provide a total replacement.
Maintenance-Linked Warranty
Manufacturers require you to have annual maintenance on your system to ensure it runs safely and efficiently. With our detailed, documented maintenance services, rest assured your system is protected and maintains its warranties.
Comprehensive Protection Plans
We are not only confident in our products but our expert installations, too. Our comprehensive protection plans provide you with coverage on parts and labor, including major components such as compressors and heat exchangers.
Warranties for Your Protection
We believe in consumer protection and long-term relationships. In addition to our guarantees, we offer the following warranties on heating, air conditioning, solar, and roofing projects. At Legacy, we stand behind our work and offer service support long after your installation is complete.
- HVAC: 10-year parts and labor warranty on most installs
- Solar: 25-year product warranties (panel and inverter dependent) + workmanship guarantee
- Batteries: 10-year product warranty (varies slightly by brand—e.g., Enphase, Tesla Powerwall, etc.)
- Roofs: Roof replacements tied to solar installations come with 30–50 year material warranties, depending on the roofing system used

Lin M.
Extremely happy with this company! Highly recommend as you won’t be disappointed. Cody installed our Nest Thermostat and explained how to use it - made it super easy and user friendly for us. Professional and friendly- I’d give more stars if I could!
Cindy P.
This company was recommended to me by a friend. I am so glad I called them. They really took the time to understand my problem and find the best solution for me. While others were quoting me very expensive replacement units, they offered me easy fixes that were in line with my budget and future plans. I could not recommend them high enough and will be saving there contact info for future projects.

If you want quality , honesty , commitment and dedicated service look nowhere else. Cody with Legacy Energy went far and beyond to get our family set up with solar. His vast experience and knowledge really surprised us. Quality of work and efficiency was outstanding ! My family is extremely happy we made the right choice with hiring Legacy. Thank you Cody !!

I had a lot of questions and concerns going into our HVAC project, but Cody made the whole thing easy. He explained everything clearly, showed up on time, and treated our home with respect. Super friendly and trustworthy—exactly the kind of company you want working in your home.
