No overselling, no guesswork — just a Air Conditioning Repair crew that diagnoses it right the first time. Emergency dispatch available across Lilburn and the surrounding zip codes.
No automated menus for emergencies — a real person handles the call.
You'll get a flat-rate quote before any repair work begins — no guessing what the final bill will look like.
If anything feels off after we leave, a follow-up call gets a technician back out to make it right.
Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. 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.
You won't find us buried under layers of call-center scripts — we're the company that tells you what actually needs fixing instead of what pads the ticket. We carry the credentials Lilburn inspectors and property managers expect to see, and we keep that documentation available on request for every job, routine or emergency.
Being local matters more than most companies let on. That local knowledge shapes the maintenance schedules we recommend — 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 Lilburn 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'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 Lilburn 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 Lilburn rooftop unit. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.
Whether it's a mid-summer breakdown or a planned system replacement, our Lilburn techs handle it with the same level of care.
When your Air Conditioning Repair system fails without warning, waiting days for an appointment isn't an option. Our Lilburn dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.
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.
If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Lilburn homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.
We protect floors and entryways during the install and haul away the old equipment so you're not left dealing with disposal.
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 Lilburn, with after-hours work to avoid disrupting business.
We understand that a commercial call isn't just about comfort, it's about keeping a business open.
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 Lilburn households that want more than just temperature control.
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.
We'd rather set clear expectations upfront than make vague promises we can't back up.
If the same issue returns within the warranty period, we come back and fix it at no additional labor cost.
We quote a flat rate before work begins and that number doesn't change once you approve it.
A technician doesn't consider the job done until the system is tested and performing correctly.
Most breakdowns don't happen without warning — they announce themselves for weeks before the system actually quits.
A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.
This is one of the most common complaints we hear on service calls across Lilburn.
A tune-up often identifies exactly what's driving the extra energy use.
A system that won't hold a steady cycle is often fighting a sizing issue, a thermostat problem, or a refrigerant imbalance.
A musty smell often points to mold or moisture buildup somewhere in the ductwork.
We'll always tell you honestly when a repair is the better call versus when it isn't.
We explain diagnostic fees and repair estimates before authorizing work.
Dispatchers give you a realistic arrival window instead of a vague "sometime today".
If something isn't right after we leave, we come back and make it right.
Every technician carries current state licensing and manufacturer training.
We explain what failed, why it failed, and what the options are.
Replacement systems don't have to be paid in one lump sum.
We don't write these — our customers do.
"I called three other companies first and this was the only one that actually picked up. The pricing was exactly what they quoted over the phone."
"Signed up for the annual plan after our first repair and it's paid for itself already. You can tell these guys actually know what they're doing."
"They handled the whole install in a single day, exactly like they said they would. Would recommend to anyone in Lilburn needing a real replacement, not a patch job."
"Our restaurant's rooftop unit went down on a Friday night and they had someone out fast. Kept our kitchen running through the weekend rush."
"Got quotes from four different companies for a replacement and this was the only one that actually walked me through the load calculation. Installation crew was in and out in a day and left the space cleaner than they found it."
"Diagnosed a failed capacitor and had it swapped within the hour. This is the company I'm saving in my phone now."
Understanding what typically fails helps homeowners know what to watch for and when a repair call is worth making before things get worse.
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.
Setting a programmable or smart thermostat to a consistent schedule reduces the number of times the system has to work hard to catch up to a big temperature swing. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.
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.
Every tech on our Lilburn roster goes through background checks, licensing verification, and ongoing manufacturer training.
Manufacturer-certified across multiple major residential equipment lines.
Keeps the emergency truck stocked based on what actually fails most often locally.
Experienced with the light industrial and retail equipment common across the area.
Standard appointments are usually scheduled within 24-48 hours, while true emergencies jump the queue.
We explain the diagnostic fee upfront and provide a flat-rate repair quote once the issue is identified.
We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.
We maintain current credentials because it protects both our customers and our team.
As a general guideline, if a system is past 12-15 years old and facing a costly repair, replacement often makes more financial sense.
Ask your technician about current plan pricing during any service call.
We cover Lilburn and the surrounding communities, including the zip codes listed in our coverage section below.
Yes, we run separate residential and commercial divisions, both fully licensed and equipped for their respective equipment.
Yes, we service systems regardless of who originally installed them.
Ask about financing during your in-home estimate to see what fits your situation.
Twice-yearly maintenance is the standard we recommend given the temperature swings the area sees.
Check that the thermostat has power and the batteries aren't dead, and check your breaker panel for a tripped switch before calling.
We'd rather quote it honestly on the phone than have you feel ambushed by the bill.
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.
For commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.
Housing stock varies a lot across Lilburn — 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 Lilburn property, ask about setting up a standing service account so every request gets handled under one consistent agreement.
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 Lilburn installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
We dispatch throughout Lilburn and the neighboring communities, keeping response times tight because our trucks stay close to home.
Coverage isn't limited to a single neighborhood or subdivision — our Lilburn dispatch zone stretches across the metro area and into the surrounding suburbs and unincorporated communities.
