About Leonard HVAC

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC grew one honest service call at a time in communities like Greenbrae. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Greenbrae, CA.

We're not the biggest name in Greenbrae — 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.

Being local matters more than most companies let on. That local knowledge shapes the maintenance schedules we recommend — it's the difference between a tech who's guessing and a tech who's seen your exact situation a hundred times before.

Too many homeowners in Greenbrae have a story about a tech who showed up late, quoted one price, and charged another. 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 Greenbrae 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 Greenbrae rooftop unit. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

What We Handle

From Emergency Repairs To Full Installs

We cover the full range of heating, cooling, and air quality work Greenbrae properties actually need.

Priority

Same-Day Emergency Dispatch

When your Furnace Repair system fails without warning, waiting days for an appointment isn't an option. Our Greenbrae dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.

  • No-heat and no-cool emergency response
  • Refrigerant leak detection and repair
  • Temporary fixes when parts require special order

Once a technician is on-site, the goal is always a same-visit repair — most emergency calls in Greenbrae get resolved in a single trip, not a multi-day back-and-forth.

Residential

Home Heating & Cooling System Upgrades

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Greenbrae homeowners through financing and rebate options where available before a single piece of equipment gets ordered.

  • Heat pump and hybrid system installs
  • Manual J load calculations, not rough guesses
  • Post-install performance testing

We protect floors and entryways during the install and haul away the old equipment so you're not left dealing with disposal.

Commercial

Commercial Furnace Repair Service

Commercial equipment operates differently than a residential unit, and it needs technicians who actually understand rooftop packages and multi-zone systems. Our commercial division services rooftop units and package systems across Greenbrae, with service agreements built around your operating hours.

  • Rooftop unit repair and replacement
  • Energy efficiency assessments for older buildings
  • Single point of contact for multi-location businesses

Property managers working with multiple Greenbrae locations can set up a standing account so every site gets consistent service history and pricing.

Maintenance

Seasonal Tune-Ups & Indoor Air Quality

A seasonal tune-up catches the kind of wear that turns into a mid-summer no-cool call. Beyond standard tune-ups, we also handle duct cleaning and sealing to stop conditioned air from leaking into attics and crawlspaces for Greenbrae households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • Duct sealing and cleaning
  • Discounted repair rates for plan members

A tune-up typically takes under an hour and covers the checkpoints most likely to catch a problem before it becomes a breakdown.

Our Guarantee

What Happens If Something's Not Right

Guarantees only mean something if a company actually honors them, so here's exactly what ours covers.

Labor Backed In Writing

Details vary by job type and are always shared upfront, never buried in fine print.

No Inflated Emergency Rates

If a competitor's written quote for the same scope of work is genuinely lower, ask us about it.

We Check Back

If anything feels off after we leave, one call gets a tech back to your Greenbrae address.

Don't Wait Until It Fails

How To Tell If Your System Is About To Fail

Most breakdowns don't happen without warning — they announce themselves for weeks before the system actually quits.

Unusual Noises

A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.

Airflow That's Dropped Off

If some rooms stay hot or cold no matter what the thermostat says, the system may be struggling to distribute air evenly.

Energy Costs Climbing With No Explanation

Gradual efficiency loss is easy to miss month to month, but it adds up fast over a season.

Frequent On-Off Cycling

This is one of the warning signs we recommend not waiting on.

Strange Odors

A burning smell should never be ignored — it can indicate an electrical issue that needs immediate attention.

You've Called For The Same Issue Twice

If you're calling about the same problem every few months, the underlying cause likely hasn't been fully addressed.

What Sets Us Apart

The Difference Between A Repair That Sticks And One That Doesn't

Real Customer Feedback

What Our Customers Are Saying

We don't write these — our customers do.

★★★★★

"I called three other companies first and this was the only one that actually picked up. No pressure to buy a whole new system when a repair was all we needed."

James H.
Greenbrae resident

★★★★★

"Scheduled a fall tune-up and they caught a cracked part before it became a real problem. Never once felt like I was being upsold on something I didn't need."

Robert K.
Greenbrae resident

★★★★★

"Explained the sizing calculation so I understood why they weren't just installing the same unit again. Would recommend to anyone in Greenbrae needing a real replacement, not a patch job."

Karen L.
Homeowner in Greenbrae

★★★★★

"As a property manager, having a company that actually answers after-hours calls is rare. Documentation for our records was thorough and easy to file."

Tony's Kitchen
Commercial client

★★★★★

"The estimate matched the final invoice exactly, down to the dollar. Installation crew was in and out in a day and left the space cleaner than they found it."

Dennis W.
Greenbrae, CA

★★★★★

"Called at 11pm during a heat wave and honestly didn't expect anyone to pick up, let alone show up. No overnight surcharge shock — the price matched what dispatch quoted me on the phone."

Why Systems Fail

The Most Common Causes Behind Our Service Calls

Understanding what typically fails helps homeowners know what to watch for and when a repair call is worth making before things get worse.

Airflow RestrictionThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Slow Leaks Over TimeLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Worn Start ComponentsCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

Getting Your System Ready For The Season Ahead

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. Before the heaviest cooling months hit, it's worth having the refrigerant charge checked, the condenser coils cleaned, and the filter replaced — all of which directly affect how hard the compressor has to work.

Setting a programmable or smart thermostat to a consistent schedule reduces the number of times the system has to work hard to catch up to a big temperature swing. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

Equipment We Service

Whether your Greenbrae 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.
