Three Steps From Broken To Fixed

1. Tell Us What's Happening

Our Lilburn dispatcher asks a few quick questions to gauge urgency and get you the fastest available window.

2. Get A Clear Number Before Anything Starts

Ask as many questions as you want; we'd rather over-explain than leave you unsure.

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.

Local & Licensed

A Local Hvac Crew Built for Lilburn's Climate

Leonard HVAC grew one honest service call at a time in communities like Lilburn. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Lilburn, GA.

We're not the biggest name in Lilburn — we're the company that tells you what actually needs fixing instead of what pads the ticket. Licensing and insurance aren't optional line items for us, 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 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.

Ask around Lilburn and you'll hear the same complaint about a lot of HVAC companies. 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 Lilburn 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 Lilburn homes, and realistic scheduling given local demand. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

What We Handle

Hvac in Lilburn — Done Right, Not Just Done Fast

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

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 Lilburn dispatch team moves emergency tickets to the front of the schedule so a technician is diagnosing your system as fast as physically possible.

  • Same-day diagnostic and repair
  • Refrigerant leak detection and repair
  • Transparent emergency pricing before work begins

Once a technician is on-site, the goal is always a same-visit repair — most emergency calls in Lilburn get resolved in a single trip, not a multi-day back-and-forth.

Home Comfort

Residential Hvac Installation & Replacement

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Lilburn homeowners through financing and rebate options where available before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Proper ductwork sizing and sealing
  • Manufacturer warranty registration handled for you

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

Facilities

Business & Facility Heating and Cooling

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 Lilburn, with service agreements built around your operating hours.

  • Multi-zone building system service
  • 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

Seasonal Tune-Ups & Indoor Air Quality

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 Lilburn households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • Indoor air quality testing and upgrades
  • Reminder scheduling so nothing gets missed

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

What Happens If Something's Not Right

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

Repairs That Are Guaranteed

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

No Inflated Emergency Rates

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

Satisfaction Follow-Up

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

A little attention to how your system is running can save you a lot of money and discomfort.

Unusual Noises

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.

Bills Creeping Up Month Over Month

Gradual efficiency loss is easy to miss month to month, but it adds up fast over a season.

Frequent On-Off Cycling

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

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.

Reviews

Reviews From Around Lilburn

We don't write these — our customers do.

★★★★★

"The furnace stopped working overnight and someone was at our door before 9am. No pressure to buy a whole new system when a repair was all we needed."

Marcus T.
Lilburn resident

★★★★★

"We've used them for our maintenance plan for two years now and never had a surprise breakdown. Never once felt like I was being upsold on something I didn't need."

Angela M.
Homeowner in Lilburn

★★★★★

"Explained the sizing calculation so I understood why they weren't just installing the same unit again. Followed up a week later just to check everything was still running fine."

Michael D.
Lilburn resident

★★★★★

"As a property manager, having a company that actually answers after-hours calls is rare. Kept our kitchen running through the weekend rush."

Tony's Kitchen
Lilburn business

★★★★★

"Got quotes from four different companies for a replacement and this was the only one that actually walked me through the load calculation. My energy bill dropped noticeably the first month with the new system."

Dennis W.
Lilburn resident

★★★★★

"Called at 11pm during a heat wave and honestly didn't expect anyone to pick up, let alone show up. Genuinely relieved to have found a crew that answers when it matters."

Common Causes

Why Hvac Systems Fail in Lilburn Homes

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

Neglected Filter ChangesA filter left too long forces the system to work harder and shortens component lifespan
Slow Leaks Over TimeRequires a licensed technician to locate, repair, and properly recharge
Electrical & Capacitor FailuresCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Thermostat MalfunctionsA 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. 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.

No Brand Restrictions

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.

How quickly can someone get to my house?

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.

What emergency Hvac services are available in Lilburn?

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

Is Leonard HVAC a licensed HVAC contractor?

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

How do I know if I need a repair or a full replacement?

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 Lilburn?

Our dispatch area extends throughout the greater Lilburn region and nearby towns within Lilburn, GA.

Are you equipped for commercial rooftop units?

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?

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

Do you offer financing for new system installations?

Ask about financing during your in-home estimate to see what fits your situation.

How often should I schedule maintenance in Lilburn?

Twice-yearly maintenance is the standard we recommend given the temperature swings the area sees.

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.

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

We'd rather quote it honestly on the phone than have you feel ambushed by the bill.

What's the average time on-site for a service call?

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.

Is my presence required during the appointment?

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

Neighborhoods We Serve
