How It Works

What To Expect When You Call +1-866-805-8548

1. Tell Us What's Happening

Call +1-866-805-8548 and describe what your system is doing — the symptoms help us send a tech prepared with the right parts.

2. Diagnosis & Upfront Quote

A licensed technician arrives, runs a full diagnostic, and explains exactly what's wrong in plain language.

3. Job Finished, Then Checked Again

Most repairs are completed same-visit, and we test the system before we leave to confirm it's actually holding.

Who We Are

A Local Hvac Crew Built for Union Furnace's Climate

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 team that shows up in the truck, not a subcontractor we've never met. We carry the credentials Union Furnace inspectors and property managers expect to see, 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 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 Union Furnace and you'll hear the same complaint about a lot of HVAC companies. 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 Furnace 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 Furnace 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.

Priority

24/7 Emergency Heating & Cooling Repair

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 Union Furnace 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

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

Residential

New System Installs & Full Replacements

If your unit is past its expected service life, running loud, or spiking your utility bill, a replacement conversation is worth having. We walk Union Furnace homeowners through load calculations so the new system is sized correctly for the actual square footage before a single piece of equipment gets ordered.

  • Heat pump and hybrid system installs
  • Manual J load calculations, not rough guesses
  • Post-install performance testing

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.

  • Filter, coil, and refrigerant level checks
  • Indoor air quality testing and upgrades
  • Discounted repair rates for plan members

Maintenance plan members in Union Furnace get scheduling reminders automatically, so tune-ups don't fall through the cracks during a busy season.

What We Promise

What Happens If Something's Not Right

Guarantees only mean something if a company actually honors them, so here's exactly what ours covers.

Repairs That Are Guaranteed

Details vary by job type and are always shared upfront, never buried in fine print.

Fair Pricing, Verified

If a competitor's written quote for the same scope of work is genuinely lower, ask us about it.

Satisfaction Follow-Up

If anything feels off after we leave, one call gets a tech back to your Union Furnace address.

Don't Wait Until It Fails

How To Tell If Your System Is About To Fail

Most breakdowns don't happen without warning — they announce themselves for weeks before the system actually quits.

Unusual Noises

Rattling during startup often means a component has worked itself loose and needs tightening before it causes real damage.

Weak or Uneven Airflow

Weak airflow from the vents often traces back to a clogged filter, a failing blower motor, or leaking ductwork.

Energy Costs Climbing With No Explanation

A system working harder than it should to hit the same temperature shows up directly on your utility bill.

Short Cycling

A system that won't hold a steady cycle is often fighting a sizing issue, a thermostat problem, or a refrigerant imbalance.

Odors Coming From The Vents

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 Sets Us Apart

Quoted Before We Start

We explain diagnostic fees and repair estimates before authorizing work.

Common Causes

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 Union Furnace's seasonal swings.

Dirty or Clogged FiltersWe check this first on nearly every service call
Low Refrigerant ChargeLeaks often develop slowly at joints or coils and go unnoticed until performance drops noticeably
Worn Start ComponentsUsually a quick, affordable fix once diagnosed correctly
Wiring IssuesA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Keeping Your System Healthy Year-Round

Seasonal Hvac Tips for Union Furnace Homeowners

Union Furnace'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.

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.

Before You Call

What You Should Know Before You Book

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

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?

Yes — every job gets a clear quote before any repair work begins, so there are no surprise line items on the invoice.

What emergency Hvac services are available in Union Furnace?

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

Are your technicians licensed and insured?

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.

Is a service agreement worth it?

Ask your technician about current plan pricing during any service call.

How far do your technicians travel?

If you're unsure whether your address falls in our service area, a quick call to +1-866-805-8548 will confirm it.

Can you service both residential and commercial systems?

Yes, we run separate residential and commercial divisions, both fully licensed and equipped for their respective equipment.

Do you service all HVAC brands or only certain ones?

Our technicians are trained across the major residential and commercial equipment lines, not limited to a single manufacturer.

What if I can't pay for a new system all at once?

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

How many times a year should my system be serviced?

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

How do I stay safe until the tech gets here?

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?

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

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

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.

Is my presence required during the appointment?

For most residential visits, yes, an adult should be present to grant access and approve any quoted work.

Close To Home

Serving Every Corner of Union Furnace

Housing stock varies a lot across Union Furnace — 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.

Making A Replacement Affordable

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