Warranty details are explained clearly so you know exactly what's covered going forward.

Local & Licensed

Straight Answers. Certified Techs. Real Availability.

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.

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. We carry the credentials Dunbar inspectors and property managers expect to see, and we keep that documentation available on request for every job, residential or commercial.

Dunbar's climate swings hard, and generic national playbooks don't always fit. 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.

Too many homeowners in Dunbar have a story about a tech who showed up late, quoted one price, and charged another. That's the gap we built Leonard HVAC to close. We track arrival windows, callback rates, and repeat-issue complaints internally so problems get caught before they become patterns, because a customer who trusts us once tends to call us again — and Dunbar 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 Dunbar rooftop unit. Our warranty and service history records stay attached to your address, so any future technician who visits already has the full picture.

Our Services

From Emergency Repairs To Full Installs

Every service below is backed by the same licensing, warranty, and upfront pricing you get on any job we run.

Emergency

Emergency Emergency Hvac Repair

When your Emergency Hvac system fails without warning, waiting days for an appointment isn't an option. Our Dunbar dispatch team prioritizes no-heat and no-cooling calls so a technician is diagnosing your system as fast as physically possible.

  • After-hours and weekend dispatch
  • Fully stocked trucks for common failures
  • Safety shutoffs when a system poses a hazard

Once a technician is on-site, the goal is always a same-visit repair — most emergency calls in Dunbar get resolved in a single trip, not a multi-day back-and-forth.

Installation

Residential Emergency Hvac Installation & Replacement

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Dunbar homeowners through efficiency ratings and how they translate into real monthly savings before a single piece of equipment gets ordered.

  • Ductless mini-split installation
  • Smart thermostat setup and integration
  • Manufacturer warranty registration handled for you

We protect floors and entryways during the install and haul away the old equipment so you're not left dealing with disposal.

Commercial Climate Control Solutions

Downtime in a commercial space costs money every hour a system is offline. Our commercial division services multi-zone commercial buildouts across Dunbar, with after-hours work to avoid disrupting business.

  • Commercial refrigeration-adjacent HVAC support
  • Energy efficiency assessments for older buildings
  • Single point of contact for multi-location businesses

We understand that a commercial call isn't just about comfort, it's about keeping a business open.

Maintenance

Seasonal Tune-Ups & Indoor Air Quality

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 Dunbar households that want more than just temperature control.

  • Seasonal tune-ups, spring and fall
  • UV light and filtration system installs
  • Annual maintenance plans with priority scheduling

A tune-up typically takes under an hour and covers the checkpoints most likely to catch a problem before it becomes a breakdown.

What We Promise

What Happens If Something's Not Right

This is the standard every Dunbar technician on our team is held to.

Labor Backed In Writing

Every repair comes with a workmanship warranty explained in plain terms before we leave.

Price Match Commitment

We quote a flat rate before work begins and that number doesn't change once you approve it.

Not Finished Until You Say So

A technician doesn't consider the job done until the system is tested and performing correctly.

What To Watch For

Signs Your Emergency Hvac System Needs Attention Now

Catching these signs early usually means a same-day repair instead of an emergency call at the worst possible moment.

New Sounds From The Unit

A healthy system runs with a consistent, low hum — banging, screeching, or grinding usually points to a loose part or failing motor.

Some Rooms Never Get Comfortable

If some rooms stay hot or cold no matter what the thermostat says, the system may be struggling to distribute air evenly.

Bills Creeping Up Month Over Month

Gradual efficiency loss is easy to miss month to month, but it adds up fast over a season.

Frequent On-Off Cycling

This is one of the warning signs we recommend not waiting on.

Musty, Burning, or Chemical Smells

A musty smell often points to mold or moisture buildup somewhere in the ductwork.

Repeat Breakdowns On The Same System

If you're calling about the same problem every few months, the underlying cause likely hasn't been fully addressed.

What Actually Breaks Down

What's Usually Behind A Breakdown

None of these are unusual or embarrassing — they're just the normal wear and tear that comes with running a system through Dunbar's seasonal swings.

Dirty or Clogged FiltersWe check this first on nearly every service call
Low Refrigerant ChargeA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Motor StrainUsually a quick, affordable fix once diagnosed correctly
Wiring IssuesWe test the thermostat early in every diagnostic to rule this out
Local Climate Considerations

Getting Your System Ready For The Season Ahead

Dunbar'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.

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.

No Brand Restrictions

We Service Every Major System Type

We also service package units common on manufactured and modular homes throughout the Dunbar 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.

Before You Call

What You Should Know Before You Book

What's your typical response time in Dunbar?

Standard appointments are usually scheduled within 24-48 hours, while true emergencies jump the queue.

Will I know the cost before you begin the repair?

We explain the diagnostic fee upfront and provide a flat-rate repair quote once the issue is identified.

Can you come out at night or on weekends?

We staff after-hours dispatch specifically because HVAC failures rarely happen on a convenient schedule.

Is Leonard HVAC a licensed HVAC contractor?

We maintain current credentials because it protects both our customers and our team.

How do I know if I need a repair or a full replacement?

Our technicians walk you through the actual numbers — repair cost versus remaining system life versus new equipment efficiency — before making a recommendation.

Do you offer maintenance plans in Dunbar?

Plan members typically see fewer surprise breakdowns because small issues get caught during routine visits.

Do you service the zip codes near Dunbar?

We cover Dunbar and the surrounding communities, including the zip codes listed in our coverage section below.

Are you equipped for commercial rooftop units?

Property managers and business owners can request a dedicated point of contact for ongoing service.

Can you work on a system installed by another company?

If parts require special ordering for a less common brand, we'll communicate that timeline upfront.

Can I finance a full HVAC replacement?

Ask about financing during your in-home estimate to see what fits your situation.

How often should I schedule maintenance in Dunbar?

Systems that run harder due to heavy year-round use may benefit from more frequent check-ins.

What should I do while I'm waiting for a technician during an emergency?

Beyond basic safety checks, it's best to leave diagnosis to a licensed technician rather than attempting a repair yourself.

Will an emergency call cost more?

Ask about current after-hours rates when you call +1-866-805-8548.

How long does a typical repair take once the tech arrives in Dunbar?

Straightforward fixes like a capacitor swap or a thermostat replacement are often finished in well under an hour.

Do I need to be home for a maintenance visit or repair in Dunbar?

Let dispatch know ahead of time if access will be handled differently than a standard homeowner visit.

Close To Home

Serving Every Corner of Dunbar

Housing stock varies a lot across Dunbar — older homes often still run original ductwork that needs different care than the sealed, high-efficiency systems going into newer builds.

Larger properties get the same upfront pricing and licensed technicians as a single-family service call, just coordinated at scale.

Payment Options

Spreading Out The Cost Of A New System

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 Dunbar installation, our technicians will flag it during the estimate rather than leaving you to track it down after the fact.
