About Leonard HVAC

The Hvac Installation Team Granville Homeowners Actually Trust

Leonard HVAC grew one honest service call at a time in communities like Granville. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

We're not the biggest name in Granville — 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, big or small.

Being local matters more than most companies let on. 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. 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 Granville 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 Granville's housing stock.

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

Emergency

24/7 Emergency Heating & Cooling Repair

A dead system in the middle of a heat wave or a cold snap isn't just inconvenient — it can be a real safety issue for kids, pets, and older residents. Our Granville dispatch team prioritizes no-heat and no-cooling calls so a technician is diagnosing your system as fast as physically possible.

  • Same-day diagnostic and repair
  • Electrical and control board diagnostics
  • Temporary fixes when parts require special order

If a specialty part genuinely does need to be ordered, we'll set up a safe temporary fix and give you a real timeline instead of leaving you guessing.

24/7 Emergency Hvac Installation experts in Granville, IL
Residential

Residential Hvac Installation Installation & Replacement

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Granville homeowners through load calculations so the new system is sized correctly for the actual square footage before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Proper ductwork sizing and sealing
  • 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.

  • Multi-point safety and efficiency inspections
  • UV light and filtration system installs
  • Reminder scheduling so nothing gets missed

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

What We Promise

A Promise We Actually Stand Behind

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

Workmanship Warranty

Every repair comes with a workmanship warranty explained in plain terms before we leave.

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

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

Don't Wait Until It Fails

What Granville Homeowners Should Watch For

Catching these signs early usually means a same-day repair instead of an emergency call at the worst possible moment.

Unusual Noises

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

Airflow That's Dropped Off

If some rooms stay hot or cold no matter what the thermostat says, the system may be struggling to distribute air evenly.

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

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

Strange Odors

Chemical odors may signal a refrigerant leak, which requires a licensed technician to handle safely.

You've Called For The Same Issue Twice

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

Common Causes

The Most Common Causes Behind Our Service Calls

Understanding what typically fails helps homeowners know what to watch for and when a repair call is worth making before things get worse.

Neglected Filter ChangesThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Slow Leaks Over TimeLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Electrical & Capacitor FailuresCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Miscalibrated ControlsWe test the thermostat early in every diagnostic to rule this out
Keeping Your System Healthy Year-Round

Seasonal Hvac Installation Tips for Granville Homeowners

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. 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.

Equipment We Service

Not Limited To One Manufacturer

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

What's your typical response time in Granville?

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?

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

Do you offer 24/7 emergency repair?

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

Do you carry insurance for work done in my home?

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

Is it worth fixing my old system or should I replace it?

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 Granville?

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

How far do your technicians travel?

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

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.

Do you service all HVAC brands or only certain ones?

Our technicians are trained across the major residential and commercial equipment lines, not limited to a single manufacturer.

Can I finance a full HVAC replacement?

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

What's a normal tune-up schedule?

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.

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 Granville?

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.
