Who We Are

A Local Hvac Crew Built for Gillespie'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.

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.

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

Trust in this industry gets eroded fast, and it takes real consistency to earn it back. 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 Gillespie 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 Gillespie homes, and realistic scheduling given local demand. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

Our Services

Complete Hvac Coverage for Gillespie Homes & Businesses

We cover the full range of heating, cooling, and air quality work Gillespie properties actually need.

Emergency

24/7 Emergency Heating & Cooling Repair

When your Hvac system fails without warning, waiting days for an appointment isn't an option. Our Gillespie dispatch team moves emergency tickets to the front of the schedule so a technician is diagnosing your system as fast as physically possible.

  • No-heat and no-cool emergency response
  • 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 Gillespie get resolved in a single trip, not a multi-day back-and-forth.

Installation

Residential Hvac Installation & Replacement

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Gillespie homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.

  • Heat pump and hybrid system installs
  • Manual J load calculations, not rough guesses
  • Post-install performance testing

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.

Business

Commercial Hvac Service

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 multi-zone commercial buildouts across Gillespie, with after-hours work to avoid disrupting business.

  • Commercial refrigeration-adjacent HVAC support
  • Scheduled after-hours service windows
  • Single point of contact for multi-location businesses

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

Air Quality

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 duct cleaning and sealing to stop conditioned air from leaking into attics and crawlspaces for Gillespie households that want more than just temperature control.

  • Multi-point safety and efficiency inspections
  • Duct sealing and cleaning
  • Annual maintenance plans with priority scheduling

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

Our Guarantee

The Leonard HVAC Guarantee

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.

No Inflated Emergency Rates

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

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.

Some Rooms Never Get Comfortable

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

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.

Short Cycling

This is one of the warning signs we recommend not waiting on.

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

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

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 Gillespie's seasonal swings.

Dirty or Clogged FiltersThe 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
Motor StrainOften 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
Local Climate Considerations

What Gillespie 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.

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.

Brands & System Types

Not Limited To One Manufacturer

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

FAQ

What You Should Know Before You Book

How fast can a Hvac technician arrive in Gillespie, IL?

For emergency no-heat or no-cool calls, we prioritize dispatch and aim to have a technician on-site the same day, often within a couple of hours.

How does your pricing work?

Yes — every job gets a clear quote before any repair work begins, so there are no surprise line items on the invoice.

Do you offer 24/7 emergency repair?

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

Is Leonard HVAC a licensed HVAC contractor?

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

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 Gillespie?

Plan members typically see fewer surprise breakdowns because small issues get caught during routine visits.

What areas around Gillespie do you serve?

Our dispatch area extends throughout the greater Gillespie region and nearby towns within Gillespie, IL.

Can you service both residential and commercial systems?

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?

Most Gillespie homes benefit from two tune-ups a year — one before cooling season and one before heating season.

What should I do while I'm waiting for a technician during an emergency?

Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.

Do you charge extra for after-hours or weekend calls in Gillespie?

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

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.
