About Leonard HVAC

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC didn't start as a franchise chasing volume. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout San Lorenzo, CA.

We're not the biggest name in San Lorenzo — 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, routine or emergency.

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.

Too many homeowners in San Lorenzo 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 San Lorenzo is a small enough community that reputation travels fast.

That local context saves time on every call, because we're not starting from zero on basic questions about your neighborhood or your system. We keep parts inventory stocked based on what actually fails most often on San Lorenzo's housing stock.

  • No-heat and no-cool emergency response

Installation

Residential Hvac Installation Installation & Replacement

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk San Lorenzo homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Smart thermostat setup and integration
  • Clean, respectful installation crews

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.

Commercial

Commercial Hvac Installation 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 light industrial and warehouse ventilation across San Lorenzo, with service agreements built around your operating hours.

  • Multi-zone building system service
  • Preventive maintenance contracts for property managers
  • Priority response tiers for commercial accounts

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

Maintenance

Preventive Maintenance & Specialized Solutions

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 San Lorenzo households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • Indoor air quality testing and upgrades
  • Reminder scheduling so nothing gets missed

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

The Leonard HVAC Guarantee

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

What To Watch For

Signs Your Hvac Installation System Needs Attention Now

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

New Sounds From The Unit

Rattling during startup often means a component has worked itself loose and needs tightening before it causes real damage.

Weak or Uneven Airflow

This is one of the most common complaints we hear on service calls across San Lorenzo.

Bills Creeping Up Month Over Month

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

System Turns On and Off Repeatedly

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

Musty, Burning, or Chemical Smells

Chemical odors may signal a refrigerant leak, which requires a licensed technician to handle safely.

You've Called For The Same Issue Twice

We'll always tell you honestly when a repair is the better call versus when it isn't.

Real Customer Feedback

Real Reviews From Real San Lorenzo Customers

★★★★★

"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.
San Lorenzo, CA

★★★★★

"Signed up for the annual plan after our first repair and it's paid for itself already. Techs are always polite, always on time, and clean up after themselves."

Robert K.
Homeowner in San Lorenzo

★★★★★

Karen L.
San Lorenzo resident

Tony's Kitchen
Commercial client

★★★★★

Common Causes

What's Usually Behind A Breakdown

After thousands of service calls across San Lorenzo, a handful of causes show up again and again.

Dirty or Clogged FiltersWe check this first on nearly every service call
Slow Leaks Over TimeRequires a licensed technician to locate, repair, and properly recharge
Worn Start ComponentsUsually a quick, affordable fix once diagnosed correctly
Miscalibrated ControlsSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Keeping Your System Healthy Year-Round

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 coldest stretch of the year, a heating system benefits from a full safety inspection, checking the heat exchanger, ignition system, and airflow to catch any issue that could turn into a no-heat emergency.

Simple habits between professional visits also matter. 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

Whether your San Lorenzo 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.

Our Team

Licensed Techs, Not Anonymous Contractors

Every tech on our San Lorenzo roster goes through background checks, licensing verification, and ongoing manufacturer training.

Do you carry insurance for work done in my home?

How do I know if I need a repair or a full replacement?

Do you offer maintenance plans in San Lorenzo?

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

How far do your technicians travel?

Can you service both residential and commercial systems?

Do you offer financing for new system installations?

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

What's a normal tune-up schedule?

Twice-yearly maintenance is the standard we recommend given the temperature swings the area sees.

How do I stay safe until the tech gets here?

Check that the thermostat has power and the batteries aren't dead, and check your breaker panel for a tripped switch before calling.

Do you charge extra for after-hours or weekend calls in San Lorenzo?

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?

Straightforward fixes like a capacitor swap or a thermostat replacement are often finished in well under an hour.

Can someone else let the technician in?

Let dispatch know ahead of time if access will be handled differently than a standard homeowner visit.

Close To Home

Serving Every Corner of San Lorenzo

Housing stock varies a lot across San Lorenzo — older homes often still run original ductwork that needs different care than the sealed, high-efficiency systems going into newer builds.

If you manage several units or a shared system across a San Lorenzo property, ask about setting up a standing service account so every request gets handled under one consistent agreement.

Financing

Spreading Out The Cost Of A New System

Qualifying installations can be financed through options we'll walk you through during your in-home estimate, with terms explained clearly before you commit to anything. If a rebate or local incentive program applies to your San Lorenzo installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
