We fix what's broken, fast, and we don't disappear after the invoice. Same-day appointments available across Santa Rosa and the surrounding zip codes.

No automated menus for emergencies — a real person handles the call.
Ask as many questions as you want; we'd rather over-explain than leave you unsure.
Warranty details are explained clearly so you know exactly what's covered going forward.
Leonard HVAC didn't start as a franchise chasing volume. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.
We're not interested in being the cheapest quote on the page — we're the company that tells you what actually needs fixing instead of what pads the ticket. Licensing and insurance aren't optional line items for us, and we keep that documentation available on request for every job, residential or commercial.
We know which neighborhoods run on older ductwork and which subdivisions were built with newer high-efficiency systems. That local knowledge shapes the parts we stock on the truck — it's the difference between a tech who's guessing and a tech who's seen your exact situation a hundred times before.
Trust in this industry gets eroded fast, and it takes real consistency to earn it back. That's the gap we built Leonard HVAC to close. We track arrival windows, callback rates, and repeat-issue complaints internally so problems get caught before they become patterns, because a customer who trusts us once tends to call us again — and Santa Rosa is a small enough community that reputation travels fast.
Our office team is based locally too, not routed through an out-of-state call center that's never seen a Santa Rosa rooftop unit. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.
We cover the full range of heating, cooling, and air quality work Santa Rosa properties actually need.
Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Santa Rosa dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.
Once a technician is on-site, the goal is always a same-visit repair — most emergency calls in Santa Rosa get resolved in a single trip, not a multi-day back-and-forth.

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Santa Rosa homeowners through load calculations so the new system is sized correctly for the actual square footage before a single piece of equipment gets ordered.
We protect floors and entryways during the install and haul away the old equipment so you're not left dealing with disposal.

A retail floor, a restaurant kitchen, or an office suite can't run without stable climate control. Our commercial division services rooftop units and package systems across Santa Rosa, with after-hours work to avoid disrupting business.
Property managers working with multiple Santa Rosa locations can set up a standing account so every site gets consistent service history and pricing.

Most emergency breakdowns start as a small, ignorable warning sign months earlier. Beyond standard tune-ups, we also handle humidifier, dehumidifier, and air purifier installation for Santa Rosa households that want more than just temperature control.
Maintenance plan members in Santa Rosa get scheduling reminders automatically, so tune-ups don't fall through the cracks during a busy season.

Guarantees only mean something if a company actually honors them, so here's exactly what ours covers.
Details vary by job type and are always shared upfront, never buried in fine print.
We quote a flat rate before work begins and that number doesn't change once you approve it.
If anything feels off after we leave, one call gets a tech back to your Santa Rosa address.
Most breakdowns don't happen without warning — they announce themselves for weeks before the system actually quits.
A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.
Weak airflow from the vents often traces back to a clogged filter, a failing blower motor, or leaking ductwork.
A tune-up often identifies exactly what's driving the extra energy use.
A system that won't hold a steady cycle is often fighting a sizing issue, a thermostat problem, or a refrigerant imbalance.
A burning smell should never be ignored — it can indicate an electrical issue that needs immediate attention.
We'll always tell you honestly when a repair is the better call versus when it isn't.
You'll know the cost before a wrench touches your system.
Dispatchers give you a realistic arrival window instead of a vague "sometime today".
Parts and labor are backed by warranty terms explained in plain language.
We run background checks because you're letting someone into your home.
We explain what failed, why it failed, and what the options are.
We'll walk you through what's actually available before you decide.
Every review below reflects an actual service call in the Santa Rosa area.
"I called three other companies first and this was the only one that actually picked up. Fixed on the first visit and explained everything in terms I could actually understand."
"Scheduled a fall tune-up and they caught a cracked part before it became a real problem. Techs are always polite, always on time, and clean up after themselves."
"Had a full system replacement done and it was the smoothest home project I've had in years. Would recommend to anyone in Santa Rosa needing a real replacement, not a patch job."
"Our restaurant's rooftop unit went down on a Friday night and they had someone out fast. Documentation for our records was thorough and easy to file."
"I appreciated that they didn't try to sell me a bigger unit than I needed. My energy bill dropped noticeably the first month with the new system."
"Diagnosed a failed capacitor and had it swapped within the hour. No overnight surcharge shock — the price matched what dispatch quoted me on the phone."
After thousands of service calls across Santa Rosa, a handful of causes show up again and again.
Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.
Clearing debris, leaves, and overgrown landscaping away from an outdoor condenser unit gives it room to breathe and keeps it running efficiently. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.
Whether your Santa Rosa home has a traditional split system, a ductless mini-split, a heat pump, or a hybrid dual-fuel setup, our crews are equipped to diagnose and repair it. If your system was installed by a different company entirely, that's not a problem — we service equipment regardless of who originally put it in, and we'll pull the model and serial information to confirm parts compatibility before any repair begins.
Every tech on our Santa Rosa roster goes through background checks, licensing verification, and ongoing manufacturer training.

We cover Santa Rosa and the surrounding communities, including the zip codes listed in our coverage section below.
Our commercial team handles rooftop units, multi-zone systems, and facility contracts alongside our standard residential repair work.
Our technicians are trained across the major residential and commercial equipment lines, not limited to a single manufacturer.
Ask about financing during your in-home estimate to see what fits your situation.
Systems that run harder due to heavy year-round use may benefit from more frequent check-ins.
Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.
Our pricing is explained clearly before dispatch, and any after-hours consideration is communicated upfront — never as a surprise on the final invoice.
More involved repairs, like a coil replacement or a refrigerant leak repair, take longer and the tech will give you a realistic estimate before starting.
For commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.
Our technicians are familiar with both, which means less time spent figuring out your specific setup and more time actually fixing the problem.
We also work regularly with homeowners associations, property management companies, and multi-unit buildings throughout Santa Rosa.
We accept standard payment methods for repairs and smaller jobs, and we'll always tell you upfront what a given service is likely to cost so there's no last-minute scramble to figure out payment. If a rebate or local incentive program applies to your Santa Rosa installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
