If anything feels off after we leave, a follow-up call gets a technician back out to make it right.

About Leonard HVAC

The Furnace Repair Team Calistoga Homeowners Actually Trust

Leonard HVAC didn't start as a franchise chasing volume. 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. We carry the credentials Calistoga inspectors and property managers expect to see, 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 Calistoga 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 Calistoga 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 Calistoga homes, and realistic scheduling given local demand. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

Priority

24/7 Emergency Heating & Cooling Repair

  • No-heat and no-cool emergency response
  • Fully stocked trucks for common failures
  • Transparent emergency pricing before work begins

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

New System Installs & Full Replacements

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Calistoga homeowners through load calculations so the new system is sized correctly for the actual square footage before a single piece of equipment gets ordered.

  • Full system replacements, furnace to condenser
  • Manual J load calculations, not rough guesses
  • 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.

Maintenance Plans & Specialty Repairs

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 Calistoga households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • Duct sealing and cleaning
  • 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.

Our Guarantee

The Leonard HVAC Guarantee

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

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

If a competitor's written quote for the same scope of work is genuinely lower, ask us about it.

We Check Back

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

What To Watch For

What Calistoga Homeowners Should Watch For

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

Banging, Clicking, or Grinding Sounds

Ignoring new noises is one of the fastest ways to turn a small repair into a major one.

Some Rooms Never Get Comfortable

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

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.

Frequent On-Off Cycling

Short cycling puts extra wear on the compressor and shortens the system's overall lifespan.

Odors Coming From The Vents

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

Repeat Breakdowns On The Same System

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

Danielle R.
Homeowner in Calistoga

★★★★★

Angela M.
Calistoga resident

★★★★★

"Explained the sizing calculation so I understood why they weren't just installing the same unit again. Followed up a week later just to check everything was still running fine."

Michael D.
Calistoga resident

★★★★★

"As a property manager, having a company that actually answers after-hours calls is rare. Documentation for our records was thorough and easy to file."

Tony's Kitchen
Calistoga business

★★★★★

"Got quotes from four different companies for a replacement and this was the only one that actually walked me through the load calculation. Installation crew was in and out in a day and left the space cleaner than they found it."

Dennis W.

"Called at 11pm during a heat wave and honestly didn't expect anyone to pick up, let alone show up. This is the company I'm saving in my phone now."

Common Causes

What's Usually Behind A Breakdown

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

Neglected Filter ChangesThe 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
Electrical & Capacitor FailuresUsually a quick, affordable fix once diagnosed correctly
Miscalibrated ControlsWe test the thermostat early in every diagnostic to rule this out
Keeping Your System Healthy Year-Round

What Calistoga 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.

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.

Common Questions

Questions Calistoga Customers Ask Us Most

How fast can a Furnace Repair technician arrive in Calistoga, CA?

Because our trucks are staged near Calistoga, average arrival windows run faster than what national chains typically offer.

Do you provide upfront pricing before starting work?

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

Can you come out at night or on weekends?

We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.

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?

We never push a replacement when a straightforward repair will genuinely solve the problem.

What does your maintenance plan include?

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

Do you service the zip codes near Calistoga?

We cover Calistoga 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.

Do you service all HVAC brands or only certain ones?

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?

We understand a full system replacement is a significant expense, which is why flexible payment options exist.

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.

How do I stay safe until the tech gets here?

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?

Our pricing is explained clearly before dispatch, and any after-hours consideration is communicated upfront — never as a surprise on the final invoice.

How long should I expect the visit to take?

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

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

For most residential visits, yes, an adult should be present to grant access and approve any quoted work.

Neighborhoods We Serve

We accept standard payment methods for repairs and smaller jobs, and we'll always tell you upfront what a given service is likely to cost so there's no last-minute scramble to figure out payment. If a rebate or local incentive program applies to your Calistoga installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
