Our Madison-based crews carry the parts and the know-how to get your air moving again today. Same-day appointments available across Madison and the surrounding zip codes.
No automated menus for emergencies — a real person handles the call.
A licensed technician arrives, runs a full diagnostic, and explains exactly what's wrong in plain language.
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.
We're not the biggest name in Madison — we're the company that tells you what actually needs fixing instead of what pads the ticket. Every job we run is backed by full liability coverage and current state licensing, and we keep that documentation available on request for every job, big or small.
Being local matters more than most companies let on. 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.
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 Madison 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 Madison rooftop unit. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.
We cover the full range of heating, cooling, and air quality work Madison properties actually need.
Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Madison dispatch team moves emergency tickets to the front of the schedule 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 Madison get resolved in a single trip, not a multi-day back-and-forth.
An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Madison homeowners through load calculations so the new system is sized correctly for the actual square footage 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.
Downtime in a commercial space costs money every hour a system is offline. Our commercial division services rooftop units and package systems across Madison, with after-hours work to avoid disrupting business.
Our commercial techs are trained to work around your customers and staff, scheduling noisy or disruptive work outside peak hours whenever possible.
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 indoor air quality upgrades for homes with allergy or asthma concerns for Madison households that want more than just temperature control.
Maintenance plan members in Madison get scheduling reminders automatically, so tune-ups don't fall through the cracks during a busy season.
Guarantees only mean something if a company actually honors them, so here's exactly what ours covers.
Details vary by job type and are always shared upfront, never buried in fine print.
Emergency dispatch never comes with a hidden surcharge sprung on you after the fact.
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.
This is one of the most common complaints we hear on service calls across Madison.
A tune-up often identifies exactly what's driving the extra energy use.
Short cycling puts extra wear on the compressor and shortens the system's overall lifespan.
Chemical odors may signal a refrigerant leak, which requires a licensed technician to handle safely.
If you're calling about the same problem every few months, the underlying cause likely hasn't been fully addressed.
You'll know the cost before a wrench touches your system.
Emergency calls get moved to the front of the line automatically.
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.
We explain what failed, why it failed, and what the options are.
Maintenance plan members get priority scheduling and discounted rates.
A snapshot of the feedback that keeps us accountable.
"The furnace stopped working overnight and someone was at our door before 9am. Fixed on the first visit and explained everything in terms I could actually understand."
"Signed up for the annual plan after our first repair and it's paid for itself already. Techs are always polite, always on time, and clean up after themselves."
"Explained the sizing calculation so I understood why they weren't just installing the same unit again. Would recommend to anyone in Madison needing a real replacement, not a patch job."
"Commercial dispatch was quick and the tech understood our system without needing to be walked through it. Now our go-to for every property in the portfolio."
"I appreciated that they didn't try to sell me a bigger unit than I needed. 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.
Madison's seasonal swings put real stress on a system that isn't maintained regularly. 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.
We also service package units common on manufactured and modular homes throughout the Madison area. 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.
We don't outsource dispatch to a call center that's never met our technicians.
Over a decade in residential heating and cooling, with a focus on load calculations and full system replacements.
Keeps the emergency truck stocked based on what actually fails most often locally.
Focuses on commercial rooftop units, multi-zone systems, and facility maintenance contracts.

If you're unsure whether your address falls in our service area, a quick call to +1-866-805-8548 will confirm it.
Our commercial team handles rooftop units, multi-zone systems, and facility contracts alongside our standard residential repair work.
Our technicians are trained across the major residential and commercial equipment lines, not limited to a single manufacturer.
Ask about financing during your in-home estimate to see what fits your situation.
Most Madison homes benefit from two tune-ups a year — one before cooling season and one before heating season.
Check that the thermostat has power and the batteries aren't dead, and check your breaker panel for a tripped switch before calling.
Ask about current after-hours rates when you call +1-866-805-8548.
Most standard repairs are completed in under two hours once the technician has diagnosed the issue and you've approved the quote.
Let dispatch know ahead of time if access will be handled differently than a standard homeowner visit.
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 Madison 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 Madison installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
We dispatch throughout Madison and the neighboring communities, keeping response times tight because our trucks stay close to home.
If you're on the edge of our listed zip codes, it's still worth a call, since routes and coverage get adjusted as demand shifts.
