Leonard HVAC grew one honest service call at a time in communities like Delafield. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.
You won't find us buried under layers of call-center scripts — 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 Delafield inspectors and property managers expect to see, and we keep that documentation available on request for every job, residential or commercial.
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 Delafield is a small enough community that reputation travels fast.
That local context saves time on every call, because we're not starting from zero on basic questions about your neighborhood or your system. 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 Delafield properties actually need.
A dead system in the middle of a heat wave or a cold snap isn't just inconvenient — it can be a real safety issue for kids, pets, and older residents. Our Delafield dispatch team prioritizes no-heat and no-cooling calls 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 Delafield 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 Delafield homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.
Most installs in Delafield are completed in a single day, and we walk you through the new thermostat and any app controls before we leave.
A retail floor, a restaurant kitchen, or an office suite can't run without stable climate control. Our commercial division services rooftop units and package systems across Delafield, 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 duct cleaning and sealing to stop conditioned air from leaking into attics and crawlspaces for Delafield 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.
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.
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.
Rattling during startup often means a component has worked itself loose and needs tightening before it causes real damage.
This is one of the most common complaints we hear on service calls across Delafield.
Gradual efficiency loss is easy to miss month to month, but it adds up fast over a season.
Short cycling puts extra wear on the compressor and shortens the system's overall lifespan.
A burning smell should never be ignored — it can indicate an electrical issue that needs immediate attention.
If you're calling about the same problem every few months, the underlying cause likely hasn't been fully addressed.
No inflated "emergency surcharge" games — the number we quote is the number you pay.
Because our trucks are stationed near Delafield, we're rarely far from your address.
Parts and labor are backed by warranty terms explained in plain language.
Every technician carries current state licensing and manufacturer training.
You make the final call — we just make sure you have the full picture.
We'll walk you through what's actually available before you decide.
We don't write these — our customers do.
"The furnace stopped working overnight and someone was at our door before 9am. The pricing was exactly what they quoted over the phone."
"Scheduled a fall tune-up and they caught a cracked part before it became a real problem. 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 Delafield needing a real replacement, not a patch job."
"As a property manager, having a company that actually answers after-hours calls is rare. 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. Would use them again without hesitation."
"The tech walked me through what he was checking as he went, which I really appreciated. 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.
The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. 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.
Whether your Delafield home has a traditional split system, a ductless mini-split, a heat pump, or a hybrid dual-fuel setup, our crews are equipped to diagnose and repair it. 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 Delafield roster goes through background checks, licensing verification, and ongoing manufacturer training.
Manufacturer-certified across multiple major residential equipment lines.
Known for fast, accurate diagnostics on no-heat and no-cool breakdowns.
Experienced with the light industrial and retail equipment common across the area.
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.
Our policy is simple: you approve the number before we touch the system.
Our emergency line runs 24 hours a day, including nights, weekends, and holidays.
Yes — licensing and insurance documentation is available on request for any job, residential or commercial.
We never push a replacement when a straightforward repair will genuinely solve the problem.
Yes, our maintenance plans include seasonal tune-ups, priority scheduling, and discounted repair rates for members.
We cover Delafield and the surrounding communities, including the zip codes listed in our coverage section below.
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.
We understand a full system replacement is a significant expense, which is why flexible payment options exist.
Twice-yearly maintenance is the standard we recommend given the temperature swings the area sees.
Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.
Our pricing is explained clearly before dispatch, and any after-hours consideration is communicated upfront — never as a surprise on the final invoice.
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 Delafield — 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 Delafield 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 Delafield installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
We dispatch throughout Delafield and the neighboring communities, keeping response times tight because our trucks stay close to home.
Property managers with multiple Delafield addresses can consolidate everything under one account for simpler scheduling and consistent pricing across every location.
