We fix what's broken, fast, and we don't disappear after the invoice. Same-day appointments available across Platteville and the surrounding zip codes.
Our Platteville dispatcher asks a few quick questions to gauge urgency and get you the fastest available window.
A licensed technician arrives, runs a full diagnostic, and explains exactly what's wrong in plain language.
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 Platteville, CO.
We're not interested in being the cheapest quote on the page — we're the team that shows up in the truck, not a subcontractor we've never met. Licensing and insurance aren't optional line items for us, 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 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 Platteville and you'll hear the same complaint about a lot of HVAC companies. 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 Platteville 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 Platteville rooftop unit. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.
Whether it's a mid-summer breakdown or a planned system replacement, our Platteville techs handle it with the same level of care.
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 Platteville dispatch team prioritizes no-heat and no-cooling calls 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.
An aging system that's constantly breaking down usually costs more to keep patching than to replace. We walk Platteville 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.
Downtime in a commercial space costs money every hour a system is offline. Our commercial division services multi-zone commercial buildouts across Platteville, with priority response for facilities that can't afford downtime.
Property managers working with multiple Platteville locations can set up a standing account so every site gets consistent service history and pricing.
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 indoor air quality upgrades for homes with allergy or asthma concerns for Platteville 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.
This is the standard every Platteville technician on our team is held to.
If the same issue returns within the warranty period, we come back and fix it at no additional labor cost.
Emergency dispatch never comes with a hidden surcharge sprung on you after the fact.
Our office follows up after major repairs and installs to confirm everything is holding.
Catching these signs early usually means a same-day repair instead of an emergency call at the worst possible moment.
Rattling during startup often means a component has worked itself loose and needs tightening before it causes real damage.
If some rooms stay hot or cold no matter what the thermostat says, the system may be struggling to distribute air evenly.
A system working harder than it should to hit the same temperature shows up directly on your utility bill.
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.
Repeated repairs on an aging system are usually the clearest sign that replacement will save more money than another patch job.
You'll know the cost before a wrench touches your system.
Emergency calls get moved to the front of the line automatically.
We don't consider a job finished until the system is actually performing correctly.
Our techs recognize brand-specific quirks instead of learning your system on the job.
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. No pressure to buy a whole new system when a repair was all we needed."
"Scheduled a fall tune-up and they caught a cracked part before it became a real problem. Never once felt like I was being upsold on something I didn't need."
"Explained the sizing calculation so I understood why they weren't just installing the same unit again. Would recommend to anyone in Platteville needing a real replacement, not a patch job."

After thousands of service calls across Platteville, a handful of causes show up again and again.
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.
We also service package units common on manufactured and modular homes throughout the Platteville 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.
Every tech on our Platteville roster goes through background checks, licensing verification, and ongoing manufacturer training.
Manufacturer-certified across multiple major residential equipment lines.

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.
If you're unsure whether your address falls in our service area, a quick call to +1-866-805-8548 will confirm it.
Yes, we run separate residential and commercial divisions, both fully licensed and equipped for their respective equipment.
If parts require special ordering for a less common brand, we'll communicate that timeline upfront.
We understand a full system replacement is a significant expense, which is why flexible payment options exist.
Systems that run harder due to heavy year-round use may benefit from more frequent check-ins.
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.
Most standard repairs are completed in under two hours once the technician has diagnosed the issue and you've approved the quote.
For most residential visits, yes, an adult should be present to grant access and approve any quoted work.
Our technicians are familiar with both, which means less time spent figuring out your specific setup and more time actually fixing the problem.
We also work regularly with homeowners associations, property management companies, and multi-unit buildings throughout Platteville.
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 Platteville installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
We dispatch throughout Platteville and the neighboring communities, keeping response times tight because our trucks stay close to home.
