What Happens After You Call

You'll get a flat-rate quote before any repair work begins — no guessing what the final bill will look like.

About Leonard HVAC

Straight Answers. Certified Techs. Real Availability.

Leonard HVAC grew one honest service call at a time in communities like Union. 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. 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.

We know which neighborhoods run on older ductwork and which subdivisions were built with newer high-efficiency systems. That local knowledge shapes how we diagnose problems — 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. 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 Union 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. It also means faster escalation when something's urgent — a local dispatcher can reroute the nearest truck in minutes, not hours.

What We Handle

Hvac in Union — Done Right, Not Just Done Fast

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

Priority

Emergency Hvac 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
  • Fully stocked trucks for common failures
  • Safety shutoffs when a system poses a hazard

If a specialty part genuinely does need to be ordered, we'll set up a safe temporary fix and give you a real timeline instead of leaving you guessing.

Installation

Residential Hvac Installation & Replacement

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 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

Business & Facility Heating and Cooling

Downtime in a commercial space costs money every hour a system is offline. Our commercial division services rooftop units and package systems across Union, with priority response for facilities that can't afford downtime.

  • Rooftop unit repair and replacement
  • Scheduled after-hours service windows
  • Detailed service reporting and documentation

Property managers working with multiple Union locations can set up a standing account so every site gets consistent service history and pricing.

Air Quality

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 Union households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • Duct sealing and cleaning
  • Reminder scheduling so nothing gets missed

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

Our Guarantee

A Promise We Actually Stand Behind

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

Labor Backed In Writing

If the same issue returns within the warranty period, we come back and fix it at no additional labor cost.

No Inflated Emergency Rates

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.

Don't Wait Until It Fails

How To Tell If Your System Is About To Fail

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

Banging, Clicking, or Grinding Sounds

Ignoring new noises is one of the fastest ways to turn a small repair into a major one.

Airflow That's Dropped Off

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

Bills Creeping Up Month Over Month

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

System Turns On and Off Repeatedly

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

Odors Coming From The Vents

A burning smell should never be ignored — it can indicate an electrical issue that needs immediate attention.

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.

Why Systems Fail

Why Hvac Systems Fail in Union Homes

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

Dirty or Clogged FiltersA filter left too long forces the system to work harder and shortens component lifespan
Slow Leaks Over TimeRequires a licensed technician to locate, repair, and properly recharge
Worn Start ComponentsOften shows up as clicking sounds or a system that hums but doesn't turn on
Thermostat MalfunctionsWe test the thermostat early in every diagnostic to rule this out
Seasonal Tips

Seasonal Hvac Tips for Union Homeowners

The shift between peak heating and peak cooling demand is exactly when older or neglected equipment tends to fail. Before the heaviest cooling months hit, it's worth having the refrigerant charge checked, the condenser coils cleaned, and the filter replaced — all of which directly affect how hard the compressor has to work.

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.

Common Questions

Questions Union Customers Ask Us Most

How quickly can someone get to my house?

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?

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

Do you offer 24/7 emergency repair?

Yes, no-heat and no-cool situations are treated as priority calls regardless of the hour.

Is Leonard HVAC a licensed HVAC contractor?

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

When does a repair stop making sense?

As a general guideline, if a system is past 12-15 years old and facing a costly repair, replacement often makes more financial sense.

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?

Our commercial team handles rooftop units, multi-zone systems, and facility contracts alongside our standard residential repair work.

Do you service all HVAC brands or only certain ones?

Yes, we service systems regardless of who originally installed them.

Do you offer financing for new system installations?

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

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.

Will an emergency call cost more?

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

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

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

Can someone else let the technician in?

For commercial accounts or rental properties, a designated point of contact or property manager can coordinate access instead.

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.

Financing

Financing Options for Union Homeowners

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.

Coverage includes these zip codes near Union: 29379
Both the city of Union and Union County received their names from the old Union Church that stood a short distance from the Monarch Mill. When it was first founded, the city of Union was known as Unionville; later the name was shortened to Union. The county's first white settlers came from Virginia in 1749. Union County's population grew the fastest between 1762 and the start of the Revolutionary War. Settlers built log cabins and cultivated tobacco, flax, corn and wheat. Union was one of the first towns settled in the area and was untouched during the Civil War because the Broad River flooded and turned Sherman’s troops away from the town.
