We hired Romano Builders for a complete exterior upgrade—solar installation, new roofing, and energy-efficient windows and doors. From the very first meeting, Eli was attentive and professional, offering smart solutions for everything we needed. The entire team was organized, punctual, and detailed throughout the process. They even helped us visualize the design and layout with helpful suggestions along the way. We’re already seeing the benefits in energy savings and curb appeal. Huge thanks to Eli, Lori, and the whole crew—we’re thrilled with the results and will definitely work with them again!

WHAT DO YOU NEED FOR A HOME HVAC INSTALLATION IN CALIFORNIA?
Every home is different — that’s why we don’t do one-size-fits-all HVAC. Our process begins with a full assessment of your home’s square footage, existing ductwork, insulation, and climate preferences.
Based on this, we recommend systems that meet your comfort goals while maximizing energy efficiency. We install trusted brands known for durability and performance and help you choose energy-efficient models that qualify for rebates and incentives.
From permits to setup — we manage everything so your HVAC upgrade is stress-free.
WHAT HAPPENS DURING AN HVAC INSTALLATION?
Our process starts with system design and layout planning based on your home’s needs. Once approved, we obtain all necessary permits and schedule the installation.
The installation itself includes placing indoor/outdoor units, connecting ductwork or refrigerant lines, wiring the thermostat, and testing the entire system for airflow and temperature control.
We ensure full compliance with California building codes and test every unit before final handoff. We’ll also teach you how to use your new system efficiently — so you stay comfortable and save money from day one.
HOW MUCH DOES AN HVAC SYSTEM COST IN CALIFORNIA?
Costs vary based on system type, home size, and features — but we’ll help you find a solution that fits your budget and lifestyle.
Thanks to energy-efficiency rebates, state incentives, and flexible financing options, installing a new HVAC system is more affordable than ever. Romano Builders offers transparent pricing, zero-down options, and expert guidance on financing plans.

I couldn’t be happier with the work Romano Builders did for our home! What started as an electrical upgrade turned into a full exterior refresh, including converting an old window into a beautiful sliding glass door and upgrading to an energy-efficient HVAC system. Shay, Eli, and the entire crew were incredibly professional and thorough. They truly care about the work they do and it shows in every detail. Shay’s experience was invaluable—he offered guidance and smart suggestions that made a real difference. I’m excited to team up with them again for future projects!
We hired Eli from Romano Builders to install a custom-designed front door, and the experience was outstanding. He paid close attention to every detail and made sure the job was done with precision and care. Eli showed up exactly when he said he would and ensured everything was perfect from start to finish. Highly recommend Eli and his team for anyone looking for quality windows and doors installation!
