How It Works

What To Expect When You Call +1-866-805-8548

1. Tell Us What's Happening

Our Greenbrae dispatcher asks a few quick questions to gauge urgency and get you the fastest available window.

2. We Inspect And Explain

A licensed technician arrives, runs a full diagnostic, and explains exactly what's wrong in plain language.

3. Repair & Follow-Up

Warranty details are explained clearly so you know exactly what's covered going forward.

Local & Licensed

A Local Hvac Crew Built for Greenbrae's Climate

Leonard HVAC didn't start as a franchise chasing volume. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

You won't find us buried under layers of call-center scripts — we're the company that tells you what actually needs fixing instead of what pads the ticket. We carry the credentials Greenbrae inspectors and property managers expect to see, 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 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.

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. Every dispatcher, every technician, and every follow-up call is held to the same standard, 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. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

Hvac in Greenbrae — Done Right, Not Just Done Fast

Every service below is backed by the same licensing, warranty, and upfront pricing you get on any job we run.

Emergency

Emergency Hvac Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Greenbrae dispatch team moves emergency tickets to the front of the schedule so a technician is diagnosing your system as fast as physically possible.

  • No-heat and no-cool emergency response
  • Electrical and control board diagnostics
  • Temporary fixes when parts require special order

If a specialty part genuinely does need to be ordered, we'll set up a safe temporary fix and give you a real timeline instead of leaving you guessing.

Residential

New System Installs & Full Replacements

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Greenbrae homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.

  • Heat pump and hybrid system installs
  • Proper ductwork sizing and sealing
  • Manufacturer warranty registration handled for you

Every install ends with a performance test, confirming airflow, temperature split, and refrigerant charge are all where they should be before we consider the job finished.

Business

Commercial Hvac Service

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 Greenbrae, with after-hours work to avoid disrupting business.

  • Multi-zone building system service
  • Scheduled after-hours service windows
  • Detailed service reporting and documentation

We understand that a commercial call isn't just about comfort, it's about keeping a business open.

Specialized

Maintenance Plans & Specialty Repairs

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.

  • Multi-point safety and efficiency inspections
  • Duct sealing and cleaning
  • Discounted repair rates for plan members

We'll show you photos of anything concerning we find, along with a plain-language explanation of what it means and whether it's urgent.

What We Promise

What Happens If Something's Not Right

This is the standard every Greenbrae technician on our team is held to.

Repairs That Are Guaranteed

If the same issue returns within the warranty period, we come back and fix it at no additional labor cost.

No Inflated Emergency Rates

We quote a flat rate before work begins and that number doesn't change once you approve it.

Not Finished Until You Say So

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

Warning Signs

Signs Your Hvac System Needs Attention Now

Catching these signs early usually means a same-day repair instead of an emergency call at the worst possible moment.

Unusual Noises

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

Weak or Uneven Airflow

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

A system working harder than it should to hit the same temperature shows up directly on your utility bill.

Short Cycling

Short cycling puts extra wear on the compressor and shortens the system's overall lifespan.

Musty, Burning, or Chemical Smells

A musty smell often points to mold or moisture buildup somewhere in the ductwork.

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.

Common Causes

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
Refrigerant LeaksA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Motor StrainUsually a quick, affordable fix once diagnosed correctly
Wiring IssuesSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Keeping Your System Healthy Year-Round

Seasonal Hvac Tips for Greenbrae Homeowners

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

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

Not Limited To One Manufacturer

Our technicians train across the major residential and commercial equipment lines, so you're not limited to a single brand's service network. 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.

Common Questions

Frequently Asked Questions About Hvac in Greenbrae

What's your typical response time in Greenbrae?

Because our trucks are staged near Greenbrae, average arrival windows run faster than what national chains typically offer.

Will I know the cost before you begin the repair?

Our policy is simple: you approve the number before we touch the system.

Do you offer 24/7 emergency repair?

We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.

Do you carry insurance for work done in my home?

Every technician we send is licensed in accordance with Greenbrae, CA requirements and carries full liability coverage.

Is it worth fixing my old system or should I replace it?

Our technicians walk you through the actual numbers — repair cost versus remaining system life versus new equipment efficiency — before making a recommendation.

What does your maintenance plan include?

Ask your technician about current plan pricing during any service call.

What areas around Greenbrae do you serve?

We cover Greenbrae and the surrounding communities, including the zip codes listed in our coverage section below.

Do you work on business HVAC systems too?

Our commercial team handles rooftop units, multi-zone systems, and facility contracts alongside our standard residential repair work.

What brands and system types do you work on?

If parts require special ordering for a less common brand, we'll communicate that timeline upfront.

What if I can't pay for a new system all at once?

Ask about financing during your in-home estimate to see what fits your situation.

How many times a year should my system be serviced?

Systems that run harder due to heavy year-round use may benefit from more frequent check-ins.

How do I stay safe until the tech gets here?

Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.

Is there an overnight or weekend surcharge?

We'd rather quote it honestly on the phone than have you feel ambushed by the bill.

How long should I expect the visit to take?

Most standard repairs are completed in under two hours once the technician has diagnosed the issue and you've approved the quote.

Is my presence required during the appointment?

For most residential visits, yes, an adult should be present to grant access and approve any quoted work.
