Who We Are

A Local Furnace Repair Crew Built for San Bruno's Climate

Leonard HVAC didn't start as a franchise chasing volume. We invest in ongoing training so our techs recognize a failing capacitor, a cracked heat exchanger, or a refrigerant leak before it turns into an emergency.

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, residential or commercial.

Being local matters more than most companies let on. 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.

Ask around San Bruno and you'll hear the same complaint about a lot of HVAC companies. 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 San Bruno 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. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

Emergency

Emergency Furnace Repair Repair

When your Furnace Repair system fails without warning, waiting days for an appointment isn't an option. Our San Bruno 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
  • Refrigerant leak detection and repair
  • Temporary fixes when parts require special order

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

Home Comfort

Residential Furnace Repair Installation & Replacement

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk San Bruno homeowners through financing and rebate options where available 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 San Bruno 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

A retail floor, a restaurant kitchen, or an office suite can't run without stable climate control. Our commercial division services multi-zone commercial buildouts across San Bruno, with service agreements built around your operating hours.

  • Commercial refrigeration-adjacent HVAC support
  • Energy efficiency assessments for older buildings
  • Priority response tiers for commercial accounts

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

Maintenance

Seasonal Tune-Ups & Indoor Air Quality

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 San Bruno households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • Indoor air quality testing and upgrades
  • Annual maintenance plans with priority scheduling

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

Backed By Us, Not Just Words

The Leonard HVAC Guarantee

We'd rather set clear expectations upfront than make vague promises we can't back up.

Labor Backed In Writing

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.

Satisfaction Follow-Up

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

What To Watch For

Signs Your Furnace 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.

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.

Bills Creeping Up Month Over Month

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

Short Cycling

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

Strange Odors

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

Frequent Repairs

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

Common Causes

What's Usually Behind A Breakdown

None of these are unusual or embarrassing — they're just the normal wear and tear that comes with running a system through San Bruno's seasonal swings.

Neglected Filter ChangesWe check this first on nearly every service call
Slow Leaks Over TimeA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Worn Start ComponentsCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

What San Bruno Weather Does To Your Equipment

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.

Do you provide upfront pricing before starting work?

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

What emergency Furnace Repair services are available in San Bruno?

Our emergency line runs 24 hours a day, including nights, weekends, and holidays.

Do you carry insurance for work done in my home?

Yes — licensing and insurance documentation is available on request for any job, residential or commercial.

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 San Bruno do you serve?

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

Are you equipped for commercial rooftop units?

Yes, we run separate residential and commercial divisions, both fully licensed and equipped for their respective equipment.

Can you work on a system installed by another company?

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 often should I schedule maintenance in San Bruno?

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?

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?

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

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

More involved repairs, like a coil replacement or a refrigerant leak repair, take longer and the tech will give you a realistic estimate before starting.

Do I need to be home for a maintenance visit or repair in San Bruno?

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