We fix what's broken, fast, and we don't disappear after the invoice. Same-day appointments available across Sunnyside and the surrounding zip codes.

Our Sunnyside dispatcher asks a few quick questions to gauge urgency and get you the fastest available window.
Ask as many questions as you want; we'd rather over-explain than leave you unsure.
Warranty details are explained clearly so you know exactly what's covered going forward.
Leonard HVAC grew one honest service call at a time in communities like Sunnyside. 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. Licensing and insurance aren't optional line items for us, and we keep that documentation available on request for every job, routine or emergency.
Being local matters more than most companies let on. 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.
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. 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 Sunnyside 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 Sunnyside techs handle it with the same level of care.
When your Heat Pump Repair system fails without warning, waiting days for an appointment isn't an option. Our Sunnyside 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 Sunnyside 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 Sunnyside homeowners through efficiency ratings and how they translate into real monthly savings 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 multi-zone commercial buildouts across Sunnyside, with priority response for facilities that can't afford downtime.
Property managers working with multiple Sunnyside 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 duct cleaning and sealing to stop conditioned air from leaking into attics and crawlspaces for Sunnyside 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.

Guarantees only mean something if a company actually honors them, so here's exactly what ours covers.
Every repair comes with a workmanship warranty explained in plain terms before we leave.
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.
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.
Weak airflow from the vents often traces back to a clogged filter, a failing blower motor, or leaking ductwork.
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.
No inflated "emergency surcharge" games — the number we quote is the number you pay.
Dispatchers give you a realistic arrival window instead of a vague "sometime today".
We don't consider a job finished until the system is actually performing correctly.
Every technician carries current state licensing and manufacturer training.
Photos and plain-language notes accompany every diagnostic.
We'll walk you through what's actually available before you decide.
Every review below reflects an actual service call in the Sunnyside area.
"Our AC quit on the hottest weekend of the year and they had a tech out within a couple of hours. 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. Never once felt like I was being upsold on something I didn't need."
"Had a full system replacement done and it was the smoothest home project I've had in years. New system is noticeably quieter and our energy bill actually dropped."
"Our restaurant's rooftop unit went down on a Friday night and they had someone out fast. 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. Would use them again without hesitation."
"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.
Sunnyside'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.
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 Sunnyside 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 Sunnyside roster goes through background checks, licensing verification, and ongoing manufacturer training.

Handles the majority of Sunnyside installs and specializes in properly sizing equipment for older housing stock.

Known for fast, accurate diagnostics on no-heat and no-cool breakdowns.

Focuses on commercial rooftop units, multi-zone systems, and facility maintenance contracts.
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.
We maintain current credentials because it protects both our customers and our team.
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.
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.
Our technicians are trained across the major residential and commercial equipment lines, not limited to a single manufacturer.
Financing options are available for qualifying replacement installations, and our team can walk you through what's currently offered.
Systems that run harder due to heavy year-round use may benefit from more frequent check-ins.
Check that the thermostat has power and the batteries aren't dead, and check your breaker panel for a tripped switch before calling.
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.
Let dispatch know ahead of time if access will be handled differently than a standard homeowner visit.
From the older, established streets near the center of Sunnyside to the newer developments on the outskirts, our trucks cover the full footprint of the city.
If you manage several units or a shared system across a Sunnyside 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 Sunnyside installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
Coverage extends across Sunnyside 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.
