How It Works

Three Steps From Broken To Fixed

1. Tell Us What's Happening

Our Union dispatcher asks a few quick questions to gauge urgency and get you the fastest available window.

2. We Inspect And Explain

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

3. Repair & Follow-Up

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

Local & Licensed

The Ductwork Repair Team Union Homeowners Actually Trust

Leonard HVAC didn't start as a franchise chasing volume. Our crews carry manufacturer certifications across the major residential and commercial equipment lines.

We're not the biggest name in Union — we're the team that shows up in the truck, not a subcontractor we've never met. We carry the credentials Union inspectors and property managers expect to see, and we keep that documentation available on request for every job, residential or commercial.

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.

Ask around Union and you'll hear the same complaint about a lot of HVAC companies. 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 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.

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 Ductwork Repair Repair

When your Ductwork Repair system fails without warning, waiting days for an appointment isn't an option. Our Union dispatch team sends the closest available truck first so a technician is diagnosing your system as fast as physically possible.

  • No-heat and no-cool emergency response
  • Refrigerant leak detection and repair
  • Temporary fixes when parts require special order

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

Installation

New System Installs & Full Replacements

An aging system that's constantly breaking down usually costs more to keep patching than to replace. 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.

  • Heat pump and hybrid system installs
  • Manual J load calculations, not rough guesses
  • Clean, respectful installation crews

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.

Facilities

Commercial Climate Control Solutions

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 rooftop units and package systems 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

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

Maintenance Plans & Specialty Repairs

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 indoor air quality upgrades for homes with allergy or asthma concerns for Union households that want more than just temperature control.

  • Filter, coil, and refrigerant level checks
  • UV light and filtration system installs
  • Reminder scheduling so nothing gets missed

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

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.

Unusual Noises

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

Some Rooms Never Get Comfortable

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

Rising Utility Bills

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

Frequent On-Off Cycling

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

Musty, Burning, or Chemical Smells

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

Repeat Breakdowns On The Same System

Repeated repairs on an aging system are usually the clearest sign that replacement will save more money than another patch job.

What Actually Breaks Down

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
Slow Leaks Over TimeRequires a licensed technician to locate, repair, and properly recharge
Electrical & Capacitor FailuresCapacitors and contactors wear out from routine cycling and are a frequent cause of a system that won't start
Wiring IssuesA thermostat that's lost calibration or has a wiring fault can make an otherwise healthy system seem broken
Seasonal Tips

Seasonal Ductwork Repair Tips for Union Homeowners

Union's seasonal swings put real stress on a system that isn't maintained regularly. 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.

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.

No Brand Restrictions

Not Limited To One Manufacturer

Whether your Union home has a traditional split system, a ductless mini-split, a heat pump, or a hybrid dual-fuel setup, our crews are equipped to diagnose and repair it. 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 quickly can someone get to my house?

Because our trucks are staged near Union, average arrival windows run faster than what national chains typically offer.

Do you provide upfront pricing before starting work?

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

Do you offer 24/7 emergency repair?

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

Are your technicians licensed and insured?

Every technician we send is licensed in accordance with Union, SC requirements and carries full liability coverage.

Is it worth fixing my old system or should I replace it?

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

Is a service agreement worth it?

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?

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.

Do you offer financing for new system installations?

Financing options are available for qualifying replacement installations, and our team can walk you through what's currently offered.

How many times a year should my system be serviced?

Twice-yearly maintenance is the standard we recommend given the temperature swings the area sees.

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

If you smell gas or burning, shut off the system at the breaker and step outside, then call us immediately.

Will an emergency call cost more?

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

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

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

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

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

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.
