How It Works

What To Expect When You Call +1-866-805-8548

1. Tell Us What's Happening

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. Diagnosis & Upfront Quote

A licensed technician arrives, runs a full diagnostic, and explains exactly what's wrong in plain language.

3. Repair & Follow-Up

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

Who We Are

The Hvac Maintenance Team Notre Dame Homeowners Actually Trust

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.

We're not the biggest name in Notre Dame — 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 Notre Dame inspectors and property managers expect to see, and we keep that documentation available on request for every job, big or small.

Notre Dame'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.

Too many homeowners in Notre Dame 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 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 Notre Dame 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 Notre Dame 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.

Hvac Maintenance in Notre Dame — Done Right, Not Just Done Fast

Every service below is backed by the same licensing, warranty, and upfront pricing you get on any job we run.

Emergency

24/7 Emergency Heating & Cooling Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Notre Dame 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
  • Refrigerant leak detection and repair
  • Safety shutoffs when a system poses a hazard

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

Residential

Home Heating & Cooling System Upgrades

An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Notre Dame homeowners through financing and rebate options where available before a single piece of equipment gets ordered.

  • Heat pump and hybrid system installs
  • Manual J load calculations, not rough guesses
  • Manufacturer warranty registration handled for you

Most installs in Notre Dame are completed in a single day, and we walk you through the new thermostat and any app controls before we leave.

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 light industrial and warehouse ventilation across Notre Dame, with after-hours work to avoid disrupting business.

  • Multi-zone building system service
  • Energy efficiency assessments for older buildings
  • Priority response tiers for commercial accounts

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

Specialized

Seasonal Tune-Ups & Indoor Air Quality

Preventive maintenance is the cheapest repair you'll ever pay for, because it's the one that prevents the bigger bill. Beyond standard tune-ups, we also handle duct cleaning and sealing to stop conditioned air from leaking into attics and crawlspaces for Notre Dame households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • UV light and filtration system installs
  • Discounted repair rates for plan members

We'll show you photos of anything concerning we find, along with a plain-language explanation of what it means and whether it's urgent.

What We Promise

A Promise We Actually Stand Behind

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

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

Our office follows up after major repairs and installs to confirm everything is holding.

Warning Signs

How To Tell If Your System Is About To Fail

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

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

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

Energy Costs Climbing With No Explanation

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

System Turns On and Off Repeatedly

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

Musty, Burning, or Chemical Smells

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

Frequent Repairs

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

Why Systems Fail

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.

Dirty or Clogged FiltersWe check this first on nearly every service call
Refrigerant LeaksRequires a licensed technician to locate, repair, and properly recharge
Motor StrainUsually a quick, affordable fix once diagnosed correctly
Miscalibrated ControlsA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Local Climate Considerations

What Notre Dame Weather Does To Your Equipment

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

Keeping vents unblocked by furniture and rugs helps maintain even airflow throughout the home. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

Equipment We Service

Brands & Equipment We Work On in Notre Dame

Our technicians train across the major residential and commercial equipment lines, so you're not limited to a single brand's service network. 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.

Before You Call

What You Should Know Before You Book

How quickly can someone get to my house?

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

Will I know the cost before you begin the repair?

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

What emergency Hvac Maintenance services are available in Notre Dame?

Yes, no-heat and no-cool situations are treated as priority calls regardless of the hour.

Do you carry insurance for work done in my home?

Every technician we send is licensed in accordance with Notre Dame, IN requirements and carries full liability coverage.

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.

What does your maintenance plan include?

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

What areas around Notre Dame do you serve?

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

Can you service both residential and commercial systems?

Property managers and business owners can request a dedicated point of contact for ongoing service.

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.

Do you offer financing for new system installations?

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 Notre Dame 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?

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

Is there an overnight or weekend surcharge?

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

How long should I expect the visit to take?

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 commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.

Local Coverage

Serving Every Corner of Notre Dame

Housing stock varies a lot across Notre Dame — older homes often still run original ductwork that needs different care than the sealed, high-efficiency systems going into newer builds.

Larger properties get the same upfront pricing and licensed technicians as a single-family service call, just coordinated at scale.

Payment Options

Payment Flexibility When You Need It

Qualifying installations can be financed through options we'll walk you through during your in-home estimate, with terms explained clearly before you commit to anything. If a rebate or local incentive program applies to your Notre Dame installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
