Who We Are

A Local Furnace Repair Crew Built for Berkeley's Climate

Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. 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 team that shows up in the truck, not a subcontractor we've never met. We carry the credentials Berkeley 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 how we diagnose problems — 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 Berkeley 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 Berkeley 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 Berkeley's housing stock.

Emergency Furnace Repair Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Berkeley dispatch team prioritizes no-heat and no-cooling calls 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

We keep the truck stocked with the parts that fail most often on the equipment common to Berkeley homes, which is exactly why most repairs don't require a return visit.

New System Installs & Full Replacements

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

  • Full system replacements, furnace to condenser
  • Smart thermostat setup and integration
  • Manufacturer warranty registration handled for you

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

  • Single point of contact for multi-location businesses

  • Seasonal tune-ups, spring and fall
  • UV light and filtration system installs
  • Reminder scheduling so nothing gets missed

Maintenance plan members in Berkeley get scheduling reminders automatically, so tune-ups don't fall through the cracks during a busy season.

What To Watch For

How To Tell If Your System Is About To Fail

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.

Some Rooms Never Get Comfortable

Weak airflow from the vents often traces back to a clogged filter, a failing blower motor, or leaking ductwork.

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.

System Turns On and Off Repeatedly

A system that won't hold a steady cycle is often fighting a sizing issue, a thermostat problem, or a refrigerant imbalance.

Musty, Burning, or Chemical Smells

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

Repeat Breakdowns On The Same System

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

Why Systems Fail

What's Usually Behind A Breakdown

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

Airflow RestrictionThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Low Refrigerant ChargeA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Electrical & Capacitor FailuresUsually a quick, affordable fix once diagnosed correctly
Wiring IssuesSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Local Climate Considerations

Seasonal Furnace Repair Tips for Berkeley 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.

Keeping vents unblocked by furniture and rugs helps maintain even airflow throughout the home. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

Equipment We Service

We Service Every Major System Type

We also service package units common on manufactured and modular homes throughout the Berkeley area. 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.

Before You Call

What You Should Know Before You Book

How quickly can someone get to my house?

Because our trucks are staged near Berkeley, 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.

Can you come out at night or on weekends?

Yes, no-heat and no-cool situations are treated as priority calls regardless of the hour.

Are your technicians licensed and insured?

We maintain current credentials because it protects both our customers and our team.

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

As a general guideline, if a system is past 12-15 years old and facing a costly repair, replacement often makes more financial sense.

Do you offer maintenance plans in Berkeley?

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

What areas around Berkeley do you serve?

Our dispatch area extends throughout the greater Berkeley region and nearby towns within Berkeley, CA.

Can you service both residential and commercial systems?

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

Can you work on a system installed by another company?

Yes, we service systems regardless of who originally installed them.

Do you offer financing for new system installations?

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

How often should I schedule maintenance in Berkeley?

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?

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?

Ask about current after-hours rates when you call +1-866-805-8548.

What's the average time on-site for a service call?

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?

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