Rooftop package units and split gas furnacesLoad calcs before we quote, not afterPermits pulled, inspections handledLicensed & insured (CA #1116121)Flat quotes with financing optionsA commercial furnace install is a decade-plus decision. Downtime costs money, and an oversized unit costs money every month it runs. We measure the building, price it straight, and get it in with the least disruption to your day.
We run a commercial load calc that looks at square footage, ceiling height, insulation, and how the space actually gets used. A retail floor and a mechanic's bay need different systems, even at the same square footage.

Equipment, curb adapter, crane, gas line, electrical, permits, and startup — one written price. Anything extra gets approved by you in writing before we do it.
Proper flashing, sealed penetrations, gas and condensate run to code, new economizer where it makes sense. When we leave, the roof looks better than when we got there.
Equipment financing and lease-to-own through real commercial lenders. You'll see the monthly payment on the quote, so cash flow stays predictable.
Manufacturer parts warranty plus our labor warranty, on paper, before the crane rolls up. If it acts up in the first year, we come back and fix it.
The person who quotes the job runs the install. No account manager handoff, no different crew showing up on day one. You always know who to call.
"I don't usually leave reviews but I received some of the best customer service in a long time. My AC was over 25 years old and Legendary Air got me approved for a brand new unit for less than 100 a month."
"Their tech support is fabulous. They assist not only residential customers but also other HVAC companies, like mine, by providing industry support. Thank you very much, and I hope you have continued success."
"Incredible. Their tech Rudy came out and inspected everything, and did fabulous work on our house's two units. He was kind and professional, thorough, honest, and spent the time to explain everything he found."
"My experience with Legendary Air was 5 star. I really recommend this company. They are super professional, know how to communicate properly, and most importantly are honest about their work."
"Rudy is professional and does great work. He did maintenance and a tune up on my AC unit and also serviced my family's unit. Prices are very reasonable. Great guy."
"So glad our Legendary Air tech Rudy came by. Did a great job fixing our older unit. An honest company that will not leave you stranded in the heat or cold. Very friendly and professional."
A commercial furnace install isn't a bigger version of a house swap. The unit is heavier, the ductwork is bigger, the gas line is bigger, and one bad decision on sizing costs you every month for the next fifteen years. In Hemet and San Jacinto, most commercial buildings run rooftop package units that heat and cool together, so replacing the heat side usually means touching the whole cabinet.
The first thing we do is walk the roof and the space. We check the existing curb, the gas line size, the electrical, and how the ductwork is laid out. A 25-year-old strip mall in Menifee might have ducts that were sized for a smaller unit, and simply dropping in a bigger furnace will starve half the building. We measure static pressure and airflow before we quote, so the number you see is a number that actually works.
On sizing, we run a commercial load calc. A retail floor with big glass storefront needs more heat than a warehouse with the same footprint. A restaurant with a make-up air system is a different calc again. We size for how the space is used today, not for whatever the last contractor put up there.
Install day for a rooftop package unit usually needs a crane. We coordinate the lift with your schedule so it happens before you open or after you close. We set the new curb adapter if needed, land the unit, tie in gas and electrical, run new condensate, and cycle the equipment through heat, cool, and safety checks before we hand it off. Most single-unit rooftop swaps are done in one day.
For closet or utility-room furnaces in office and medical buildings, the work is quieter but the details still matter. Proper venting, sealed transitions, a fresh thermostat and control wiring, and a filter cabinet that your team can actually change without a screwdriver and a prayer.
