Call +1-866-805-8548 and describe what your system is doing — the symptoms help us send a tech prepared with the right parts.
You'll get a flat-rate quote before any repair work begins — no guessing what the final bill will look like.
Most repairs are completed same-visit, and we test the system before we leave to confirm it's actually holding.
Leonard HVAC was built by technicians who got tired of watching homeowners get oversold. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Graniteville, SC.
We're not the biggest name in Graniteville — we're the crew that answers the phone at 2am when your furnace quits in the middle of a cold snap. Licensing and insurance aren't optional line items for us, and we keep that documentation available on request for every job, residential or commercial.
Graniteville's climate swings hard, and generic national playbooks don't always fit. 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.
Ask around Graniteville 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 Graniteville 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 Graniteville homes, and realistic scheduling given local demand. We keep parts inventory stocked based on what actually fails most often on Graniteville's housing stock.
Every service below is backed by the same licensing, warranty, and upfront pricing you get on any job we run.
When your Hvac system fails without warning, waiting days for an appointment isn't an option. Our Graniteville dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.
Once a technician is on-site, the goal is always a same-visit repair — most emergency calls in Graniteville get resolved in a single trip, not a multi-day back-and-forth.
If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Graniteville homeowners through financing and rebate options where available before a single piece of equipment gets ordered.
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.
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 Graniteville, with service agreements built around your operating hours.
Property managers working with multiple Graniteville locations can set up a standing account so every site gets consistent service history and pricing.
Most emergency breakdowns start as a small, ignorable warning sign months earlier. Beyond standard tune-ups, we also handle humidifier, dehumidifier, and air purifier installation for Graniteville households that want more than just temperature control.
A tune-up typically takes under an hour and covers the checkpoints most likely to catch a problem before it becomes a breakdown.
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.
If a competitor's written quote for the same scope of work is genuinely lower, ask us about it.
A technician doesn't consider the job done until the system is tested and performing correctly.
Catching these signs early usually means a same-day repair instead of an emergency call at the worst possible moment.
A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.
Weak airflow from the vents often traces back to a clogged filter, a failing blower motor, or leaking ductwork.
A tune-up often identifies exactly what's driving the extra energy use.
This is one of the warning signs we recommend not waiting on.
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".
Parts and labor are backed by warranty terms explained in plain language.
Our techs recognize brand-specific quirks instead of learning your system on the job.
Photos and plain-language notes accompany every diagnostic.
Maintenance plan members get priority scheduling and discounted rates.
A snapshot of the feedback that keeps us accountable.
"Our AC quit on the hottest weekend of the year and they had a tech out within a couple of hours. No pressure to buy a whole new system when a repair was all we needed."
"We've used them for our maintenance plan for two years now and never had a surprise breakdown. Techs are always polite, always on time, and clean up after themselves."
"Had a full system replacement done and it was the smoothest home project I've had in years. Followed up a week later just to check everything was still running fine."
"Commercial dispatch was quick and the tech understood our system without needing to be walked through it. Documentation for our records was thorough and easy to file."
"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."
"The tech walked me through what he was checking as he went, which I really appreciated. No overnight surcharge shock — the price matched what dispatch quoted me on the phone."
None of these are unusual or embarrassing — they're just the normal wear and tear that comes with running a system through Graniteville's seasonal swings.
Graniteville's seasonal swings put real stress on a system that isn't maintained regularly. 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.
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 Graniteville roster goes through background checks, licensing verification, and ongoing manufacturer training.
Handles the majority of Graniteville installs and specializes in properly sizing equipment for older housing stock.

If you smell gas or burning, shut off the system at the breaker and step outside, then call us immediately.
We'd rather quote it honestly on the phone than have you feel ambushed by the bill.
Most standard repairs are completed in under two hours once the technician has diagnosed the issue and you've approved the quote.
For commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.
Our technicians are familiar with both, which means less time spent figuring out your specific setup and more time actually fixing the problem.
If you manage several units or a shared system across a Graniteville property, ask about setting up a standing service account so every request gets handled under one consistent agreement.
A full system replacement is one of the bigger home expenses most people face, and we don't expect everyone to pay it in a single lump sum. If a rebate or local incentive program applies to your Graniteville installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
We dispatch throughout Graniteville and the neighboring communities, keeping response times tight because our trucks stay close to home.
Property managers with multiple Graniteville addresses can consolidate everything under one account for simpler scheduling and consistent pricing across every location.
