Local & Licensed

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC didn't start as a franchise chasing volume. We invest in ongoing training so our techs recognize a failing capacitor, a cracked heat exchanger, or a refrigerant leak before it turns into an emergency.

We're not the biggest name in De Graff — 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 De Graff inspectors and property managers expect to see, and we keep that documentation available on request for every job, residential or commercial.

De Graff's climate swings hard, and generic national playbooks don't always fit. That local knowledge shapes how we diagnose problems — 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'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 De Graff is a small enough community that reputation travels fast.

Our office team is based locally too, not routed through an out-of-state call center that's never seen a De Graff rooftop unit. We keep parts inventory stocked based on what actually fails most often on De Graff's housing stock.

Our Services

From Emergency Repairs To Full Installs

Whether it's a mid-summer breakdown or a planned system replacement, our De Graff techs handle it with the same level of care.

24/7

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 De Graff dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.

  • Same-day diagnostic and repair
  • Fully stocked trucks for common failures
  • Transparent emergency pricing before work begins

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

Residential Hvac Repair Installation & Replacement

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk De Graff homeowners through load calculations so the new system is sized correctly for the actual square footage 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

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

Facilities

Commercial Hvac Repair 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 light industrial and warehouse ventilation across De Graff, with after-hours work to avoid disrupting business.

  • Rooftop unit repair and replacement
  • Scheduled after-hours service windows
  • Single point of contact for multi-location businesses

Our commercial techs are trained to work around your customers and staff, scheduling noisy or disruptive work outside peak hours whenever possible.

Maintenance

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 humidifier, dehumidifier, and air purifier installation for De Graff households that want more than just temperature control.

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

A tune-up typically takes under an hour and covers the checkpoints most likely to catch a problem before it becomes a breakdown.

Warning Signs

Signs Your Hvac Repair System Needs Attention Now

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.

Weak or Uneven Airflow

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 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

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

Priya S.

What Actually Breaks Down

The Most Common Causes Behind Our Service Calls

None of these are unusual or embarrassing — they're just the normal wear and tear that comes with running a system through De Graff's seasonal swings.

Neglected Filter ChangesA filter left too long forces the system to work harder and shortens component lifespan
Low Refrigerant ChargeLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
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

Getting Your System Ready For The Season Ahead

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

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.

Equipment We Service

We Service Every Major System Type

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.

Local Coverage

Wherever You Are In De Graff, We're Close By

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

If you manage several units or a shared system across a De Graff property, ask about setting up a standing service account so every request gets handled under one consistent agreement.

Financing

Payment Flexibility When You Need It

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 De Graff installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
