We fix what's broken, fast, and we don't disappear after the invoice. Same-day appointments available across New Canaan and the surrounding zip codes.
Our New Canaan 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.
Warranty details are explained clearly so you know exactly what's covered going forward.
Leonard HVAC didn't start as a franchise chasing volume. 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 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.
New Canaan's climate swings hard, and generic national playbooks don't always fit. 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.
Ask around New Canaan 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 New Canaan 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. 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 New Canaan techs handle it with the same level of care.
Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our New Canaan dispatch team moves emergency tickets to the front of the schedule so a technician is diagnosing your system as fast as physically possible.
We keep the truck stocked with the parts that fail most often on the equipment common to New Canaan homes, which is exactly why most repairs don't require a return visit.
Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk New Canaan homeowners through financing and rebate options where available before a single piece of equipment gets ordered.
Most installs in New Canaan are completed in a single day, and we walk you through the new thermostat and any app controls before we leave.
Downtime in a commercial space costs money every hour a system is offline. Our commercial division services rooftop units and package systems across New Canaan, 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 New Canaan 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.
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.
If anything feels off after we leave, one call gets a tech back to your New Canaan address.
A little attention to how your system is running can save you a lot of money and discomfort.
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 New Canaan.
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.
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.
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.
We run background checks because you're letting someone into your home.
We explain what failed, why it failed, and what the options are.
Maintenance plan members get priority scheduling and discounted rates.
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."
"We've used them for our maintenance plan for two years now and never had a surprise breakdown. You can tell these guys actually know what they're doing."
"Explained the sizing calculation so I understood why they weren't just installing the same unit again. Would recommend to anyone in New Canaan 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."
"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."
"Called at 11pm during a heat wave and honestly didn't expect anyone to pick up, let alone show up. This is the company I'm saving in my phone now."
None of these are unusual or embarrassing — they're just the normal wear and tear that comes with running a system through New Canaan's seasonal swings.
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.
Clearing debris, leaves, and overgrown landscaping away from an outdoor condenser unit gives it room to breathe and keeps it running efficiently. 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 New Canaan roster goes through background checks, licensing verification, and ongoing manufacturer training.
Manufacturer-certified across multiple major residential equipment lines.
Runs point on overnight and weekend emergency calls throughout New Canaan.
Works directly with New Canaan property managers to schedule around business hours.
Standard appointments are usually scheduled within 24-48 hours, while true emergencies jump the queue.
Our policy is simple: you approve the number before we touch the system.
We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.
Every technician we send is licensed in accordance with New Canaan, CT requirements and carries full liability coverage.
We never push a replacement when a straightforward repair will genuinely solve the problem.
Ask your technician about current plan pricing during any service call.
Our dispatch area extends throughout the greater New Canaan region and nearby towns within New Canaan, CT.
Our commercial team handles rooftop units, multi-zone systems, and facility contracts alongside our standard residential repair work.
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.
Most New Canaan homes benefit from two tune-ups a year — one before cooling season and one before heating season.
Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.
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.
Our technicians are familiar with both, which means less time spent figuring out your specific setup and more time actually fixing the problem.
Larger properties get the same upfront pricing and licensed technicians as a single-family service call, just coordinated at scale.
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 New Canaan installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
Coverage extends across New Canaan proper and into the nearby zip codes listed below.
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.
