How It Works

Three Steps From Broken To Fixed

1. Talk To Our Dispatch Team

Call +1-866-805-8548 and describe what your system is doing — the symptoms help us send a tech prepared with the right parts.

2. Get A Clear Number Before Anything Starts

You'll get a flat-rate quote before any repair work begins — no guessing what the final bill will look like.

3. We Fix It And Confirm It's Right

Most repairs are completed same-visit, and we test the system before we leave to confirm it's actually holding.

Who We Are

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC grew one honest service call at a time in communities like Cotati. 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 crew that answers the phone at 2am when your furnace quits in the middle of a cold snap. Every job we run is backed by full liability coverage and current state licensing, and we keep that documentation available on request for every job, routine or emergency.

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 Cotati 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'd rather lose a job to a lower bid than win one by cutting corners on the diagnosis, because a customer who trusts us once tends to call us again — and Cotati is a small enough community that reputation travels fast.

When you call +1-866-805-8548, you're talking to someone who understands the local permitting process, the common equipment brands installed in Cotati homes, and realistic scheduling given local demand. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

What We Handle

Complete Ductwork Repair Coverage for Cotati Homes & Businesses

Priority

Same-Day Emergency Dispatch

When your Ductwork Repair system fails without warning, waiting days for an appointment isn't an option. Our Cotati 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

Installation

Residential Ductwork Repair Installation & Replacement

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Cotati homeowners through load calculations so the new system is sized correctly for the actual square footage 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

Most installs in Cotati are completed in a single day, and we walk you through the new thermostat and any app controls before we leave.

Commercial

Business & Facility Heating and Cooling

Downtime in a commercial space costs money every hour a system is offline. Our commercial division services rooftop units and package systems across Cotati, with priority response for facilities that can't afford downtime.

  • Rooftop unit repair and replacement
  • Energy efficiency assessments for older buildings
  • Priority response tiers for commercial accounts

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

Maintenance

Maintenance Plans & Specialty Repairs

Most emergency breakdowns start as a small, ignorable warning sign months earlier. Beyond standard tune-ups, we also handle indoor air quality upgrades for homes with allergy or asthma concerns for Cotati households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • Indoor air quality testing and upgrades
  • 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.

Our Guarantee

A Promise We Actually Stand Behind

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

Labor Backed In Writing

Every repair comes with a workmanship warranty explained in plain terms before we leave.

No Inflated Emergency Rates

Emergency dispatch never comes with a hidden surcharge sprung on you after the fact.

Satisfaction Follow-Up

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

Warning Signs

Signs Your Ductwork Repair System Needs Attention Now

A little attention to how your system is running can save you a lot of money and discomfort.

Unusual Noises

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

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

A tune-up often identifies exactly what's driving the extra energy use.

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.

Frequent Repairs

Repeated repairs on an aging system are usually the clearest sign that replacement will save more money than another patch job.

Why Systems Fail

What's Usually Behind A Breakdown

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

Airflow RestrictionA filter left too long forces the system to work harder and shortens component lifespan
Slow Leaks Over TimeRequires a licensed technician to locate, repair, and properly recharge
Worn Start ComponentsUsually a quick, affordable fix once diagnosed correctly
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Local Climate Considerations

Getting Your System Ready For The Season Ahead

Cotati's seasonal swings put real stress on a system that isn't maintained regularly. 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.

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.

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.
