Who We Are

The Hvac Team Cotati Homeowners Actually Trust

Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Cotati, CA.

You won't find us buried under layers of call-center scripts — 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, big or small.

Cotati's climate swings hard, and generic national playbooks don't always fit. 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.

Our office team is based locally too, not routed through an out-of-state call center that's never seen a Cotati rooftop unit. 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

Hvac in Cotati — Done Right, Not Just Done Fast

Whether it's a mid-summer breakdown or a planned system replacement, our Cotati techs handle it with the same level of care.

Priority

Same-Day Emergency Dispatch

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

  • After-hours and weekend dispatch
  • Fully stocked trucks for common failures
  • Safety shutoffs when a system poses a hazard

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

Home Comfort

Home Heating & Cooling System Upgrades

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Cotati homeowners through financing and rebate options where available before a single piece of equipment gets ordered.

  • Full system replacements, furnace to condenser
  • Proper ductwork sizing and sealing
  • 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.

Maintenance

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 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
  • UV light and filtration system installs
  • Reminder scheduling so nothing gets missed

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

A Promise We Actually Stand Behind

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

Labor Backed In Writing

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

Price Match Commitment

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

Not Finished Until You Say So

A technician doesn't consider the job done until the system is tested and performing correctly.

What To Watch For

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.

New Sounds From The Unit

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

Airflow That's Dropped Off

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

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.

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.

Frequent Repairs

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

Common Causes

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 RestrictionThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Slow Leaks Over TimeA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Worn Start ComponentsOften shows up as clicking sounds or a system that hums but doesn't turn on
Miscalibrated ControlsA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Keeping Your System Healthy Year-Round

What Cotati Weather Does To Your Equipment

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. 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

Not Limited To One Manufacturer

Whether your Cotati 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.

What emergency Hvac services are available in Cotati?

When does a repair stop making sense?

Do you offer financing for new system installations?

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.

Is there anything I can check myself before you arrive?

If you smell gas or burning, shut off the system at the breaker and step outside, then call us immediately.

Will an emergency call cost more?

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

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

Can someone else let the technician in?

For commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.
