Three Steps From Broken To Fixed

1. Call & Describe The Problem

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. We Inspect And Explain

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

The Hvac Team Janesville Homeowners Actually Trust

Leonard HVAC didn't start as a franchise chasing volume. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Janesville, IA.

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, 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 the parts we stock on the truck — 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 Janesville 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. Every dispatcher, every technician, and every follow-up call is held to the same standard, because a customer who trusts us once tends to call us again — and Janesville 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.

Complete Hvac Coverage for Janesville Homes & Businesses

Whether it's a mid-summer breakdown or a planned system replacement, our Janesville 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 Janesville dispatch team prioritizes no-heat and no-cooling calls so a technician is diagnosing your system as fast as physically possible.

  • After-hours and weekend dispatch
  • Refrigerant leak detection and repair
  • Transparent emergency pricing before work begins

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

Installation

New System Installs & Full Replacements

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Janesville 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
  • Proper ductwork sizing and sealing
  • Post-install performance testing

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

Commercial

Commercial Climate Control Solutions

Commercial equipment operates differently than a residential unit, and it needs technicians who actually understand rooftop packages and multi-zone systems. Our commercial division services rooftop units and package systems across Janesville, with after-hours work to avoid disrupting business.

  • Rooftop unit repair and replacement
  • Scheduled after-hours service windows
  • Priority response tiers for commercial accounts

We understand that a commercial call isn't just about comfort, it's about keeping a business open.

Specialized

Preventive Maintenance & Specialized Solutions

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 Janesville 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

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

What Happens If Something's Not Right

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

Workmanship Warranty

Details vary by job type and are always shared upfront, never buried in fine print.

Price Match Commitment

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

Not Finished Until You Say So

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

What To Watch For

What Janesville 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

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

Airflow That's Dropped Off

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

Rising Utility Bills

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

System Turns On and Off Repeatedly

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

Musty, Burning, or Chemical Smells

A burning smell should never be ignored — it can indicate an electrical issue that needs immediate attention.

Frequent Repairs

If you're calling about the same problem every few months, the underlying cause likely hasn't been fully addressed.

What Actually Breaks Down

The Most Common Causes Behind Our Service Calls

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

Neglected Filter ChangesWe check this first on nearly every service call
Refrigerant LeaksLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Motor StrainCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Thermostat MalfunctionsSmart thermostat installs sometimes surface wiring incompatibilities that need professional correction
Seasonal Tips

Seasonal Hvac Tips for Janesville Homeowners

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Before the coldest stretch of the year, a heating system benefits from a full safety inspection, checking the heat exchanger, ignition system, and airflow to catch any issue that could turn into a no-heat emergency.

Simple habits between professional visits also matter. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

No Brand Restrictions

We Service Every Major System Type

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

Do you provide upfront pricing before starting work?

We explain the diagnostic fee upfront and provide a flat-rate repair quote once the issue is identified.

Do you offer 24/7 emergency repair?

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

Are your technicians licensed and insured?

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

When does a repair stop making sense?

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?

Yes, our maintenance plans include seasonal tune-ups, priority scheduling, and discounted repair rates for members.

Do you service the zip codes near Janesville?

If you're unsure whether your address falls in our service area, a quick call to +1-866-805-8548 will confirm it.

Do you work on business HVAC systems too?

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?

Financing options are available for qualifying replacement installations, and our team can walk you through what's currently offered.

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?

Check that the thermostat has power and the batteries aren't dead, and check your breaker panel for a tripped switch before calling.

Will an emergency call cost more?

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

How long does a typical repair take once the tech arrives in Janesville?

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.

Can someone else let the technician in?

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