About Leonard HVAC

A Local Furnace Repair Crew Built for Union's Climate

Leonard HVAC didn't start as a franchise chasing volume. Every technician we send to your door is background-checked, factory-trained, and licensed to work on the systems installed throughout Union, OH.

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.

Too many homeowners in Union 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. 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 Union 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 Union rooftop unit. We keep parts inventory stocked based on what actually fails most often on Union's housing stock.

From Emergency Repairs To Full Installs

Whether it's a mid-summer breakdown or a planned system replacement, our Union techs handle it with the same level of care.

Emergency

Emergency Furnace Repair Repair

Breakdowns rarely happen at a convenient time, which is exactly why our emergency line runs 24 hours a day. Our Union dispatch team prioritizes no-heat and no-cooling calls so a technician is diagnosing your system as fast as physically possible.

  • No-heat and no-cool emergency response
  • Electrical and control board diagnostics
  • Safety shutoffs when a system poses a hazard

We keep the truck stocked with the parts that fail most often on the equipment common to Union homes, which is exactly why most repairs don't require a return visit.

Residential

Residential Furnace Repair Installation & Replacement

Not every repair call ends in a repair — sometimes the honest recommendation is a properly sized replacement. We walk Union homeowners through load calculations so the new system is sized correctly for the actual square footage before a single piece of equipment gets ordered.

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

Most installs in Union are completed in a single day, and we walk you through the new thermostat and any app controls before we leave.

Commercial

Commercial Furnace Repair Service

Commercial equipment operates differently than a residential unit, and it needs technicians who actually understand rooftop packages and multi-zone systems. Our commercial division services light industrial and warehouse ventilation across Union, with service agreements built around your operating hours.

  • Commercial refrigeration-adjacent HVAC support
  • Preventive maintenance contracts for property managers
  • Detailed service reporting and documentation

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

  • Multi-point safety and efficiency inspections
  • Duct sealing and cleaning
  • Discounted repair rates for plan members

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.

The Leonard HVAC Guarantee

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

Don't Wait Until It Fails

What Union Homeowners Should Watch For

A little attention to how your system is running can save you a lot of money and discomfort.

Banging, Clicking, or Grinding Sounds

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

Airflow That's Dropped Off

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

Rising Utility Bills

A tune-up often identifies exactly what's driving the extra energy use.

System Turns On and Off Repeatedly

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

Strange Odors

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

Repeat Breakdowns On The Same System

We'll always tell you honestly when a repair is the better call versus when it isn't.

Ways To Spread Out The Cost

Replacement systems don't have to be paid in one lump sum.

Common Causes

What's Usually Behind A Breakdown

Understanding what typically fails helps homeowners know what to watch for and when a repair call is worth making before things get worse.

Airflow RestrictionThe single most common cause of reduced airflow and frozen coils, and the easiest to prevent
Low Refrigerant ChargeA system low on refrigerant loses cooling capacity and puts extra strain on the compressor
Worn Start ComponentsOften shows up as clicking sounds or a system that hums but doesn't turn on
Miscalibrated ControlsA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Keeping Your System Healthy Year-Round

Getting Your System Ready For The Season Ahead

Homeowners who schedule a tune-up ahead of each season tend to call us far less often for emergency repairs. Filters should be checked monthly during heavy-use seasons and replaced roughly every 60-90 days depending on your household and any pets.

Keeping vents unblocked by furniture and rugs helps maintain even airflow throughout the home. None of this replaces a professional tune-up, but it does reduce the wear that leads to premature breakdowns between visits.

Brands & System Types

Not Limited To One Manufacturer

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.

FAQ

Questions Union Customers Ask Us Most

How fast can a Furnace Repair technician arrive in Union, OH?

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.

Do you provide upfront pricing before starting work?

Our policy is simple: you approve the number before we touch the system.

What emergency Furnace Repair services are available in Union?

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

Do you carry insurance for work done in my home?

Yes — licensing and insurance documentation is available on request for any job, residential or commercial.

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 Union?

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

How far do your technicians travel?

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

Can you service both residential and commercial systems?

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

What brands and system types do you work on?

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

Can I finance a full HVAC replacement?

We understand a full system replacement is a significant expense, which is why flexible payment options exist.

What's a normal tune-up schedule?

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

Is there anything I can check myself before you arrive?

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

Is there an overnight or weekend surcharge?

We'd rather quote it honestly on the phone than have you feel ambushed by the bill.

What's the average time on-site for a service call?

Most standard repairs are completed in under two hours once the technician has diagnosed the issue and you've approved the quote.

Is my presence required during the appointment?

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

Neighborhoods We Serve

Wherever You Are In Union, We're Close By

Our technicians are familiar with both, which means less time spent figuring out your specific setup and more time actually fixing the problem.

If you manage several units or a shared system across a Union property, ask about setting up a standing service account so every request gets handled under one consistent agreement.

Making A Replacement Affordable

Payment Flexibility When You Need It

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